Drug addiction has been one of the serious social problems. The peripheral phlebitis caused by drug injection is common, but the occurrence of pseudoaneurysm with infection of femoral artery from injection injury was rarely reported in China. From January 1995 to March 1996, six cases of injury of femoral artery with infection from heroine injection were admitted. The characteristics of the injury were described. The therapeutic measures and details of attention to be needed were discussed. It was concluded that this type of injury was different from the injury caused in agricultural, industrial or traffic accidents. The treatment of choice depended upon the type of injury.
Objective To explore the potential mechanism of Shuganning injection for non-alcoholic fatty liver disease (NAFLD) through network pharmacology and molecular docking techniques. Methods Information on the active compounds of Shuganning injection and their target proteins, as well as disease-related targets of NAFLD, were collected from multiple public databases from May 23rd to 28th, 2024, for protein interaction network analysis and pathway enrichment analysis. A multi-level network of “herb-compound-target-disease” of Shuganning injection for NAFLD was constructed. Molecular docking was performed on the top 5 key active compounds ranked in the degree centrality of the “core target-active compound” network and the core action targets. Results Finally, 140 active compounds of Shuganning injection and 486 potential targets, 1058 NAFLD-related targets, 154 common targets for NAFLD and Shuganning injection were obtained. Topological analysis of the common target protein interaction network identified 16 key target proteins of protein kinase B1, peroxisome proliferator-activated receptor alpha, peroxisome proliferator-activated receptor gamma, sterol regulatory element-binding protein 1, interleukin-6, and matrix metalloproteinase-9, etc. The gene ontology enrichment analysis showed that their genes were involved in 179 biological processes, 13 cellular components, and 48 molecular functions. The Kyoto Encyclopedia of Genes and Genomes enrichment analysis showed that their genes were involved in 99 pathways of cancer, lipid and atherosclerosis, NAFLD and insulin resistance, etc. The constructed multi-level network of “herb-compound-target-disease” consisted of 102 nodes and 208 edges. The molecular docking results showed that the 5 key active compounds of baicalin, acacetin, sitosterol, β-sitosterol, and ganoderic acid A had high affinity for the core target proteins. Conclusion Shuganning injection may exert therapeutic effects on NAFLD through active compounds like baicalin, acacetin, sitosterol, β-sitosterol and ganoderic acid A, acting on key target proteins such as protein kinase B1, peroxisome proliferator-activated receptor alpha, peroxisome proliferator-activated receptor gamma, sterol regulatory element-binding protein 1, interleukin-6, and matrix metalloproteinase-9, regulating pathways related to lipids and atherosclerosis, NAFLD, and insulin resistance.
OBJECTIVE To investigate the effects of intra-articular injection of sodium hyaluronate in post-operation treatment of the knee. METHODS From January 1998 to February 2001, 4 ml of sodium hyaluronate injection was injected into the knee joint of the 134 cases at the end of arthroscope operation, or the 91 cases undergoing open operation of the knee at the time when the drain tube was removed (treatment group). Five days after operation, the hydrarthrosis was removed and 2 ml of sodium hyaluronate was injected into the knee joint. According to the patient’s condition, injection of sodium hyaluronate was performed once a week for several weeks. Clinical evaluation was made by evaluating pain visual analog scale (VAS) and painless range of movement (ROM) of the joint at every definite point of time. The 85 patients in control group used nothing at the same time. RESULTS The VAS score of patients in the treatment group was significant lower than that of the control group. The period to the maximal painless ROM of the joint was 6 days in the treatment group after open operation, while 9 days in the control group. CONCLUSION Sodium hyaluronate appears effective in relieving post-operation pain of the knee joint.
ObjectiveTo systematically review the efficacy of Chinese medicine injection (CMI) for treating heart failure (HF).MethodsCNKI, WanFang Data, VIP, The Cochrane Library, PubMed, and EMbase databases were electronically searched from inception to January 2021 to identify randomized controlled trials (RCTs) on CMI for treating HF. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of included studies. Network meta-analysis was then performed by RevMan 5.2 software and Stata 16.0 software.ResultsA total of 47 studies were included involving 4 902 patients and 5 types of CMIs, including Shenmai, Shenfu, Yiqi Fumai (lyophilized), Shengmai, and Danhong injections. The results of network meta-analysis showed that the efficacy of combined CMIs was superior to conventional Western medicine alone. For the main efficacy, Shenmai, Shengmai, and Shenfu injections had significant advantages in improving the total clinical effectiveness. Shengmai, Shenmai, and Yiqi Fumai (lyophilized) injections were significantly more effective for reducing NT pro-BNP levels than other injections. Shenfu and Shengmai injections were significantly more effective for reducing BNP levels than other injections. Shenmai, Danhong and Shengmai injections were significantly more effective for improving the left ventricular ejection fraction than the other injections. These CMIs showed similar advantages for secondary efficacy indicators as for main efficacy indicators.ConclusionsThe combined 5 types of CMIs for treating HF can improve the clinical efficacy when compared with conventional Western medicine treatment. Shenmai injection, Yiqi Fumai injection (lyophilized), and Shengmai injection, which is part of Sheng Mai San, have clear advantages in terms of the overall curative effect or on individual indices.
A total of 109 varieties of Chinese medicine injections have been approved by the State Food and Drug Administration of China, all of which have the potential to induce adverse drug reactions (ADRs). Major ADRs include systemic anaphylaxis, anaphylactic shock, acute intravascular hemolysis, hepatorenal damage, skin lesion, cardiac damage, respiratory system injury, and gastrointestinal disorders. Contributing factors of ADRs include healthcare workers’ inadequate attention to ADRs of Chinese medicine injections, complex ingredients, allergic uncertainties, and inappropriate drug use in children and the aged. To decrease ADRs resulting from Chinese medicine injections, it is essential to improve the selection of drug indications, delivery of proper dosage regimens, compliance with drug instructions, and selection of solvents for the drugs.
OBJECTIVE: To investigate the ability of repairing bone defect with the compound of coralline hydroxyapatite porous (CHAP), fibrin sealant(FS) and staphylococcus aureus injection (SAI), and the feasibility to use the compounds as bone substitute material. METHODS: The animal model of bone defect was made on the bilateral radius of 54 New Zealand white rabbits, which were randomly divided into the experimental group(the defect was repaired with CHAP-FS-SAI), control group(with autograft) and blank control group(the defect was left unrepaired) with 18 rabbits in each group. The ability of bone defect repair was evaluated by gross observation, histopathological study, X-ray and biomechanical analysis 2, 4, 8 and 12 weeks after repair. RESULTS: (1) In the 2nd week, tight fibro-connection could be found between the implant and fracture site and there were many fibroblasts and capillary proliferation with many chondrocytes around CHAP in the experimental group, while only a few callus formed, and chondrocytes, osteoblast and osteoclast existed in the control group. (2) In experimental group and control group, a large quantity of callus was found 4 and 8 weeks; ossification of chondrocytes with weave bone formation were found 4 weeks and many osteocytes and weave bones and laminar bones were found 8 weeks. (3) In the 12th week, the complete ossification of implant with well bone remodeling, a large number of mature osteocytes and laminar were found in experimental group and control group, and CHAP still existed in the experimental group; the defect area filled with fibro-scar tissue and only many fibroblasts could be seen in blank control group. (4) X-ray findings were the following: In experimental and control groups, callus formation could be seen 2 weeks postoperatively, more callus formed 4 weeks, the bone defect area disappeared and CHAP scattered in the callus 8 weeks; the fracture line disappeared and medullary cavity became united (in control group); and in the 12th week, the cortex became continuous, the medullary cavity became united, and remodeling completed, while bone defect was not still united in blank control group. The maximal torque and torsional stiffness in the experimental group is higher than those in the control group 2 weeks (P lt; 0.05), but there was no significant difference (P gt; 0.05) between the two groups 4, 8, 12 weeks after repair. CONCLUSION: The compound of CHAP-FS-SAI has good biological compatibility, and it can be used for one kind of bone substitute material to repair the bone defect.
ObjectiveTo explore the clinical efficacy and safety of ultrasound-guided intra-articular injection of platelet-rich plasma (PRP) in the treatment of avascular necrosis of the femoral head.MethodsWe retrospectively collected and analyzed the clinical characteristics, imaging data, and clinical outcomes of patients with femoral head necrosis who received ultrasound-guided intra-articular PRP injection in the Department of Rehabilitation Medicine of Sun Yat-sen Memorial Hospital, Sun Yat-sen University between June 2019 and June 2020. All the patients received 4 injections at one-week intervals. The Visual Analogue Scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Harris Hip Joint Function Scale (HHS) were evaluated before treatment and 1 month, 3 months, and 6 months after the first injections. Adverse events were recorded. The normally distributed data were presented as mean±standard deviation, and analyzed by one-way repeated measures analysis of variance; the non-normally distributed data were presented as median (lower quartile, upper quartile), and analyzed by Friedman test.ResultsA total of 29 patients were included. According to the Association Research Circulation Osseous classification standard, 2 patients were classified as stageⅠ, 11 as stageⅡ, 11 as stage Ⅲ, and 5 as stage Ⅳ. Before treatment and 1 month, 3 months, and 6 months after treatment, the VAS scores were 7.0 (5.5, 8.0), 4.0 (3.0, 5.0), 3.0 (2.0, 3.0), and 3.0 (2.0, 5.0), respectively, the WOMAC scores were 39.27±11.70, 28.34±8.08, 22.82±6.09, and 24.13±7.55, respectively, and the HHS were 46.0 (40.0, 64.0), 71.0 (57.5, 75.0), 78.0 (68.0, 80.5), and 78.0 (64.0, 80.0), respectively. The time effects in VAS (χ2=65.423, P<0.001), WOMAC (F=46.710, P<0.001), and HHS (χ2=66.347, P<0.001) were all statistically significant. There were significant differences in each index between the values 1 month, 3 months, and 6 months after treatment and those before treatment respectively, and there was also a significant difference in each index between the value 1 month after treatment and that 3 months after treatment (P<0.05). There was no significant difference in any indicator between the value 6 months after treatment and that 3 months after treatment (P>0.05). Significant difference was shown between the value 6 months after treatment and that 1 month after treatment in WOMAC (P=0.016), but not in VAS or HHS (P>0.05). No obvious adverse event was reported during the follow-up period.ConclusionsUltrasound-guided intra-articular PRP injection can effectively alleviate the pain and improve the hip joint function of patients with femoral head necrosis for at least 6 months. However, randomized controlled studies with a larger sample size and longer-term follow-up are needed in the future to confirm the efficacy and safety of PRP injection in femoral head necrosis.
Objective To investigate the mechanism of radix salviae miltiorrhizae (RSM) injection in treatment of pancreatitis through observing the changes of activity of nuclear factor-kappa B (NF-κB) in pancreas of rats with severe acute pancreatitis (SAP) and the influence of RSM injection upon NF-κB in pancreas tissue. Methods Seventy-five rats were randomly divided into 3 groups: normal control group, SAP group and RSM treatment group, which were injected with normal saline, normal saline or RSM in the peritoneal cavity, respectively. The model of SAP rats was made by injecting L-arginine into peritoneal cavity and by subcutaneous injection at the same time. The concentrations of amylase in plasma and in ascites were measured respectively, and the expression of NF-κB in pancreas tissues was determined by immunohistochemistry. Results The levels of amylase in plasm and ascites in SAP group and RSM treatment group increased significantly with the increased expression of NF-κB in pancreas tissue, but it was also found that both the level of amylase and the expression of NF-κB in RSM treatment group were significantly lower compared with those in SAP group, and the survival time of RSM treatment group was longer than SAP group with less pathological injury in the pancreas tissues. Conclusion RSM may be effective for the treatment of pancreatitis by degrading the expression of NF-κB.
Objective To evaluate the therapeutic results of percutaneous injection of autogeous bone marrow for simple bone cyst and to analyze the prognostic factors of the treatment. Methods From March 2000 to June 2005, 31 patients with simple bone cysts were treated by percutaneous injection of autogeous bone marrow. Of 31 patients, there were 18 males and 13 females, aged 5 years and 7 months to 15 years. The locations were proximal humerus in 18 cases ,proximal femur in 7 cases and other sites in 6 cases. Two cases were treated with repeated injections. The operative process included percutaneous aspiration of fluid in the bone cysts and injection of autogenous bone marrow aspirated fromposterior superior iliac spine. The mean volume of marrow injected was 40 ml(30-70 ml).Results No complications were noted during treatment. Thirty patients were followed for an average of 2.2 years(1.5 years) with 2 cases out of follow-up. After one injection of bone marrow, 9 cysts(29.0%) were healed up completely, 7 cysts(226%)basically healed up,13 cysts (41.9%)healed up partially and 2 (6.5%) had no response.The satisfactory and effective rates were 67.7% and 93.5% respectively. There was significant difference between active stagegroup and resting stage group(P＜0.05). There were no statistically significant difference in therapeutic results between groups of different ages, lesion sites or bone marrow hyperplasia(Pgt;0.05). Conclusion Percutaneous injection of autogeous bone marrow is a safe and effective method to treat simple bone cyst, but repeated injections is necessary for some patients. The therapeutic results are better in cysts at resting stage than those at active stage.
Objective To explore the serious situation of injection abuse, and its influence to average prescription fee. Methods The subjects of this study were health service settings in rural area of 9 provinces/cities in Midwest of China. The treatment prescription indicators of county and village health service settings were calculated. Results Prescription injection rates of health care facility in rural area of Midwest provinces/cities of China (25.8% to 62.2%,mean: 45.1%) were higher than the standard of WHO (13.4% to 24.1%), and the injection abuse situation was serious. Injection bause caused the increase of prescription fee. Excess usage of injection in health service settings was related to the economic level of the on-site county or village, and also related to the size and load of health service facilities. Conclusion Suggestions are proposed to the government health agency according to the results of the study: enhancing the lawmaking, establishing the related policy and effective measure, training the medical personnel, promoting the mass health education, investigating the effective injection management model in rural area, and reducing the rate of injection.
