ObjectiveTo explore whether the growth hormone receptor (GHR) is present in human hepatocellular carcinoma (HCC). MethodsThe GHR were measured in samples of human HCC (50 cases), the liver tissues adjacent to hepatocellular carcinoma (49 cases), cirrhotic liver tissues (30 cases) and control liver tissues (30 cases) by immunohistochemistry technique. ResultsThe GHR positive expression rate was 42.0% in samples of human hepatocellular carcinoma, and 95.9% in adjacent tissue of HCC, 96.7% in cirrhotic liver tissues, and 93.3% in normal liver tissues; the significance of the differences in the GHR positive expression rate was seen between HCC and the compared groups.ConclusionThe lower expression of GHR in HCC is present. The growth hormone administration can be used in patients of HCC with radical resection or GHR negative expression patient.
【Abstract】 Objective To discuss the mechanism of growth hormone (GH) in infection and its safety. Methods Advances in the application of GH in infection of recent years were reviewed. Results In infectious patients, GH may promote protein synthesis, strengthen the immunity of body, and protect the integrity of intestinal barrier function. But some patients present GH resistance. The safety of GH for infectious patients needs further evaluation. Conclusion GH may play a supplementary role in infection therapy, but further research is needed.

ObjectiveTo investigate effect of small interfering RNA (siRNA) targeting inhibition of growth hormone receptor (GHR) on proliferation and invasion of human liver cancer line SMMC-7721. MethodsSMMC-7721 cells were transfected with siRNA targeting human GHR by GenMuteTM transfection regent.The cells were divided into three groups:blank control group (non-transfected siRNA),negative control group (transfected with non-specific siRNA),and specificity transfected group (transfected with expression specifically interfere by GHR siRNA).the relative expression of GHR mRNA was detected by using real-time PCR.the expression of GHR protein was detected by using Western blot.The cell proliferation was assessed by CCK-8 assay.And the ability of invasion was examined by Transwell assay. ResultsThe expressions of GHR mRNA and GHR protein in the specificity transfected group were significantly lower than those in the blank control group (P<0.05) and the negative control group (P<0.05).Compared with the blank control group and the negative control group,the absorbance value and the number of migrating cells of SMMC-7721 cells were decreased obviously (P<0.05) in the specificity transfected group. ConclusionsiRNA targeting human GHR could reduce capability of proliferation migration and invasion of SMMC-7721 cells.
Objective To explore the effects of recombinant human growth hormone （rhGH） on senile patients after pancreaticoduodenectomy. MethodsFortysix patients were divided into the therapeutic group (rhGH, n=17) and control group (n=29). Both were treated with parenteral nutrition. In the therapeutic group, rhGH (8 u/d) was given hypodermically for 7 days. After operation the levels of albumin, prealbumin, transferrin, and immunoglobulin were measured. Postoperative fatigue syndrome and the average length of stay in hospital were observed too. ResultsAfter operation the levels of albumin, prealbumin, transferrin, and immunoglobulin in the therapeutic group were significantly higher than those of control group. The degree of postoperative fatigue syndrome in the therapeutic group was less than that of control group. The average length of stay in hospital was significantly shortened. Conclusion The early application of rhGH in senile patients after pancreaticoduodenectomy can enhance immune function, reduce the incidence of infection, promote the postoperative recovery, shorten the average length of stay in hospital,decrease the mortality, increase the safety of operation and improve the postoperative life quality of senile patients.
ObjectiveTo explore a surgery of effective weight loss concentrating on gut hormone release. MethodsWistar rats were fed with high-fat diet for inducing obesity and which randomly divided into sleeve gastrectomy plus decent jejunoileal bypass (SJB) group (n=12), sleeve gastrectomy (SG) group (n=12), and sham operation (SO) group (n=11), the body weight reduction, food intake, plasma ghrelin level, and glucagon like peptide-1 (GLP-1) level were compared among three groups. ResultsThere were no differences of the body weight and food intake before operation among three groups (Pgt;0.05). Compared with the SO group, the body weight descended and the food intake decreased obviously on 1-8 weeks after operation in the SJB group (Plt;0.05), the body weight of rats on 1-8 weeks after operation in the SJB group significantly descended as compared with the SG group (Plt;0.05), and the food intake of rats on week 3, 6, 7, and 8 in the SJB group signicantly decreased as compared with the SG group (Plt;0.05). There were no differences of the levels of the plasma ghrelin and GLP-1 before operation among three groups (Pgt;0.05). Compared with SO group, the plasma ghrelin level decreased and the GLP-1 level increased in the SJB group and the SG group, meanwhile the SJB group significantly decreased level of plasma ghrelin and elevated level of plasma GLP-1 as compared with the SG group on week 8 after operation(Plt;0.05). ConclusionThe data demonstrate that SJB could represent an effective way of losing weight by interfering with food intake and obesity related hormone levels.
Objective To assess the effectiveness and the safety of clinical use of growth hormone (GH) in burn patients. Method Search were applied to the following electronic databases: Chinese Bio-medicine Database (CBM), MEDLINE, EMBASE and Cochrane Library. Language was restricted in Chinese and English. Data were extracted and evaluated by the two reviewers independently of each other. Applied RevMan 4.1 for statistical analyse. Results Nine trials involving 732 patients were included. The combined results showed that GH can shorten wound healing time [weighted mean difference (WMD) = -11.25, 95%CI (-14.84 to -7.66), Plt;0.000 01], donor site healing times [WMD= -1.87, 95%CI (-2.28 to -1.47), P＜0.000 01), and length of hospital stay [WMD= -8.10, 95%CI (-10.40 to -5.79), P＜0.000 01]. There was no statistical significance on resting energy expenditure [WMD= -0.04, 95%CI ( -0.08 to 0.00), P=0.06], mortality [odds ratio (OR) =1.15, 95%CI (0.15 to 8.53), P=0.9], sepsis [OR=1.08, 95%CI (0.50 to 2.34), P=0.8] and ventilatory support required [OR=1.51, 95%CI (0.72 to 3.16), P=0.3]. Nevertheless, the plasma levels of glucose [standardized mean difference (SMD) =0.98, 95%CI (0.54 to1.42), P＜0.000 01] and insulin [SMD=0.86, 95%CI (0.43 to1.30), P=0.000 1] were increased in GH groups. Conclusions GH for burn patients is effective and safe if blood glucose can be controlled well.
【Abstract】ObjectiveTo explore the mechanisms of anabolism intensified by recombination human growth hormone (GH) on the basis of total parenteral nutrition (TPN) during postoperative in gastrointestinal carcinoma patients. MethodsNinety-four gastrointestinal carcinoma patients undergone operation were randomly divided into TPN group and TPN+GH group. The levels of TNF-α, IL-1, IL-6 and CRP were detected in the first, third, seventh postoperative day. ResultsThe levels of TNF-α, IL-1, IL-6 and CRP were significantly lower in TPN+GH group than those in the TPN group at the first, third, seventh postoperative day （P＜0.01）. The levels of TNF-α, IL-1, IL-6 and CRP were significantly higher at the indicated time of postoperative days than the pre-operative days in the two groups (P＜0.01）. ConclusionBy inhibiting TNF-α, IL-1, IL-6 and CRP production in gastrointestinal carcinoma patients undergone operation and blocking high catabolism induced by inflammatory cytokines, GH promotes the synthesis of anabolism.
Objective To investigate the expression of growth hormone receptor (GHR) in human gastric cancer tissue. Methods The GHR was detected in samples of the human gastric cancer (57 cases) and the distal normal tissues (57 cases) by immunohistochemistry technique. Results The GHR expression positive rate was 80.7%(46/57) in the human gastric cancer tissues and 70.2%(40/57) in the distal normal tissues. There was no statistic difference between the human gastric cancer tissues and the distal normal tissues (Pgt;0.05). There were also no statistic differences among the gastric cancer tissues of different differentiation, different tissue type, different gender and different age ranges (Pgt;0.05). Conclusion It is similar that the expression of GHR between the human gastric cancer tissues and the distal normal tissues.
ObjectivesTo systematically review the efficacy of adjuvant growth hormone (GH) in IVF protocols.MethodsCBM, WanFang Data, CNKI, VIP, PubMed, EMbase, Web of Science and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of adjuvant GH in IVF protocols from inception to October 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, the meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 RCTs involving 691 infertile females were included. Results of meta-analysis demonstrated that adjuvant GH in IVF protocols could increase collected oocytes number (MD=1.58, 95%CI 1.29 to 1.87, P<0.000 01), MⅡ stage oocytes number (MD=2.26, 95%CI 1.77 to 2.74, P<0.000 01), implantation rate (RR=1.20, 95%CI 1.02 to 1.40, P=0.03), clinical pregnancy rate (RR=1.46, 95%CI 1.08 to 1.98, P=0.01) and live birth rate (RR=1.62, 95%CI 1.05 to 2.51, P=0.03). However, there was no difference in fertilization rate (RR=1.06, 95%CI 0.97 to 1.16, P<0.18), miscarriage rate (RR=1.44, 95%CI 0.65 to 3.17, P=0.37) and adverse reactions between two groups.ConclusionsCurrent evidence shows that GH can improve the fertility outcomes of IVF cycles in patients with POR, elderly or previous IVF failures. But due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
