OBJECTIVE: To investigate the effect of combined treatment of recombinant human growth hormone (rhGH) and insulin-like growth factor-1 (IGF-1) on wound healing and protein catabolism in burned rats. METHODS: Forty Wistar rats with deep II degree scald injury were divided randomly into four groups and received rhGH (0.1 U/kg.d), rhGH (0.1 U/kg.d) plus IGF-1 (2.0 mg/kg.d), IGF-1 (2.0 mg/kg.d) and Ringer’s solution (2 ml/kg.d, as control group) respectively. The wound healing time and protein catabolism levels of every groups were compared after 2 weeks. RESULTS: Total body weight began to increase after 2 weeks in rhGH group and rhGH plus IGF-1 group, but in control group, it was occurred after 4-5 weeks. The body weight of rhGH plus IGF-1 group was 1.65 times than that of rhGH group. The wound healing time in rhGH plus IGF-1 group (17.1 +/- 4.4) days was significantly lower than that of rhGH (20.5 +/- 4.8) days and control group (29.7 +/- 6.3) days. The protein level of rhGH plus IGF-1 group was significantly higher than that of control group and rhGH group. CONCLUSION: It suggests that rhGH plus IGF-1 with synergism is more effective in promoting wound healing and increasing the protein catabolism.
To study the effects of human growth hormone on protein catabolic state of gastric and colonic cancer patients after surgical intervention and whether it can improve the postoperative host immune function and reduce the postoperative fatigue syndrome (POF) by using rhGH. Thirtyeight gastric and colonic cancer patients (21 cases of gastric cancer; 17 cases of colonic cancer) were diveided into control group (n＝18) and rhGHtreated group (n＝20). All the patients were performed resection and treated by early postoperative intraperitoneal thermochemotherapy (EPIC) and total parenteral nutrition (TPN). Subcutaneous injections of 8 U rhGH at 9∶30 am was administered to the rhGHtreated group (six days) at the same time. Results: In the control group, a significant decrease in serum levels of albumin, prealbumin, transferri, IgG, IgA, IgM and CD＋３, CD＋4, CD＋8 were observed after operation (Ｐ＜0.01). In the rhGHtreated group, CD＋３, CD＋4 and CD＋8 raised significantly and the other did not change significantly. The postoperative vigour state of the patient was better than that in the control group. In the control group, pronouced weight loss of 3-5 kg, was detected on the 10th pastoperative day, while the weight loss was 1-2 kg in the rhGHtreated group (Ｐ＜0.01). Conclusion: The treatment with rhGH together with TPN and EPIC not only overcomes the protein catabolism of the cancer patient after operation by increasing protein synthesis, but also improves postoperative host immune function, reduces POF, and can raise the killing effect of chemotherapy on cancer cells, enhances the tolerance to chemotherapy.

ObjectiveTo investigate the role of recombinant human growth hormone (rhGH) in the treatment of patients with multiple organ dysfunction syndrome (MODS). MethodsThirty-eight patients with MODS routinely treated with antibiotics and nutrition support were divided into two groups: the rhGH group and control group. The rhGH group was treated by subcutaneous injection of 5 U rhGH for two weeks. ResultsOn the 7th day of treatment, the score of APACHE Ⅱ in the rhGH group was much higher than the control group, the levels of ALT, AST, BUN and Cre did not change much compared with the control group. The level of albumin in the rhGH group increased (P＜0.05). The stay in ICU, time of mechanical ventilation and hospital stay decreased compared with the control group (P＜0.05). ConclusionrhGH can effectively improve the pathophysiology of critically ill patients and has no side effects on the function of liver and kidney, meanwhile it can shorten hospital stay and decrease mortality.
Objective To study the effect of recombinant growth hormone (rhGH) on improvement of liver function and liver regeneration in animal and patients after hepatectomy. Methods The liver cirrhosis model of SD species mouse was set up, then the mouse were randomly divided into experiment group and control group, then 30%-40% liver of all the models were resected, rhGH was used by hypodermic injection (0.2-0.4ml/100g) in experimental group, and the equal dose of N.S. were given in control group every day. Then liver function, arterial blood ketone body ratio(AKBR), and the regenerated liver/body weight ratio (RL/W) were determined, histopathology of the cirrhosis with microscope and electron microscope and the mitotic index (MI) of liver cell on 7, 14 and 28th day after operation were observed. Clinically,39 hepatectomized patients were randomly divided into experiment group and control group, liver function, PA， Glu, RI and AKBR were measured preoperatively and on 1, 7,14th day after operation. Postoperative clinical course were also compared between the two groups. Results In the animal experiment group, as compared with the control group, AKBR was obviously higher (P＜0.01), seruim level of total protein and PA were increased faster (P＜0.05), and RL/W was higher. The mitotic index of liver cell was increased faster on 14th day, the numbers of regenerated liver cell with double nucleus and rough endoplasmic reticulum were higher in 14 and 28th day. In the clinical experiment group, as compared with the control group, serum total bilirubin, alanine aminotransferase and aspartate aminotransferase were lower on 7 and 14th postoperative day (P＜0.05). Serum albumin, PA, Glu, RI and AKBR were higher on 7, 14th postoperative day (P＜0.05). Conclusion Both experimental and clinical study show that the rhGH can promote liver regeneration and improve liver function after hepatectomy.

Methods A total of 22 children with TS were selected in the outpatients department of West China Second Hospital between January 2005 and June 2009. Twelve children with TS the average age of (13.58±2.23) years received rhGH [0.15 U/(kg•d)] every night before sleep for 4-24 months . Sixteen children with TS (age≥14 years old, bone age≥11 years old) underwent estrogen and progestogen (E/P) treatment for 3-30 months. Results The height and height standard deviation score increased significantly in children with rhGH therapy (Plt;0.01). The height velocity was (9.33±2.39) cm/year after the treatment. The treatment of estrogen and progestogen could promote the development of breast and establish menstrual cycle in children with TS. Conclusion rhGH and E/P can play a significant role in treatment of TS in children.
Objective To observe therapeutical effect of recombinant human growth hormone (rhGH) on postoperative obstructive jaundice. Methods Fourtyeight patients were divided into two groups randomly: control group with 30 patients and rhGH group with 18 patients. After operation, subcutaneous injection of rhGH was administered 8 U/d for a week. At the same time, parenteral nutrition was given to both groups until the patients could eat and drink. Biochemistry examination, endotoxin, tumor necrosis factor, sIL-2R and nutritional status were all measured at following states: before operation 1, 7 and 14 days after operation. Results Body weights of rhGH group on the fourth day after operation and that of control group on the seventh day after operation increased, but the increasing tendency of rhGH group was more prominent than the control group. For blood sugar 7 days after operation, the level of rhGH group was higher than that of control group (P＜0.05). The level of serum albumin, transferrin, prealbumin in rhGH group was higher than that of control goup （P＜0.05）. Blood serum total bile acid,total cholesterol, low density lipoprotein,glutamicoxal acetic transaminase, transglutaminase, total bilirubin, endotoxin, tumor necrosis factor and sIL-2R were all decreased compared with control group (P＜0.01). However, no significant difference was observed in renal function and electrolute between the two groups.Conclusion An improvement of nutrition status and immunologic function can be observed in obstructive jaundice patients after the postoperative administration of rhGH.
To evaluate effect of recombinant human growth hormone (rhGH) on immunologic function in patients with gastrointestinal malignant tumor (GIMT). Before and 3 weeks after surgical treatment and administration of rhGH, the amount of T lymphocyte subset (T-LS) and soluble interleukin 2 receptor (sIL-2R) level were measured in 12 patients with GIMT, which were compared with 20 cases of normal control and 18 cases of GIMT treated by surgery alone. Result: ①In all GIMT patients, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 were lower than normal control and the sIL2R level was much higher; ②After operation, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 of all patients increased, the serum sIL2R level decreased; ③In patients recieved rhGH, the serum CD＋3, CD＋4 level and the ratio of CD＋4/CD＋8 were much more increased and the serum sIL-2R level much more decreased than those of surgery alone group. Conclusion: rhGH can enhance the immunologic function of patients with GIMT.
Objective To evaluate long-term effectiveness of recombinant human growth hormone (rhGH) for children with idiopathic short stature (ISS). Methods The randomized controlled trials (RCTs) about rhGH in treating ISS published from 1985 to 2010 were searched in PubMed, ScienceDirect, EBSCOHost, EMbase, The Cochrane Library, CBM, CNKI and VIP. According to the Cochrane Handbook, two reviewers independently screened literature, extracted data, assessed methodological quality, and conducted meta-analysis using RevMan 5.0 software. Results A total of 11 RCTs involving 607 ISS children were included. The results of meta-analysis showed that, compared with the blank/placebo control group after 1-year treatment, the rhGH group resulted in a significant increase in height standard deviation score (SDS) (MD=0.29, 95%CI 0.03 to 0.54, P=0.03), growth velocity (MD=2.68 cm/year, 95%CI 1.70 to 3.65, Plt;0.000 01), and adult SDS (MD=0.46, 95%CI 0.29 to 0.63, Plt;0.000 01). Conclusion rhGH can effectively promote the growth of ISS children. But due to the limitation of quality and small sample size of the included studies, its effectiveness still needs to be further proved by more high quality RCTs.
ObjectiveThe growth potential of children with short stature in middle and late adolescence may be limited by the effect of estrogen on epiphyseal closure. In recent years, the third generation of non-steroidal aromatase inhibitors (AIs) have been used in the treatment of short stature but with off-label. This study aimed to systematically review the efficacy and safety of the third-generation non-steroidal AIs in the treatment of children with short stature, and to provide evidences for rational drug use in clinical practice. MethodsWe searched PubMed, Embase, Cochrane Library, CNKI, WanFang Data, VIP and CBM from inception to December 28, 2022. Relevant studies on the treatment for children with short stature using the recombinant human growth hormone (rhGH) combined with or without the third-generation non-steroidal AIs were collected. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 18 articles were finally included, involving 9 randomized controlled trials and 9 cohort studies, with a total of 1 053 patients. The Meta-analysis showed that: (1) in terms of efficacy, the final adult height (MD=2.48, 95%CI 2.02 to 2.94, P<0.01), predicted adult height (MD=4.27, 95%CI 2.71 to 5.83, P<0.01), predicted adult height difference (MD=4.26, 95%CI 3.23 to 5.28, P<0.01), bone age (MD=−0.62, 95%CI −0.89 to −0.36, P<0.01), bone age difference/actual age difference (MD=−0.47, 95%CI −0.56 to −0.37, P<0.01), and growth velocity (MD=1.34, 95%CI 0.89 to 1.78, P<0.01) at the end of treatment in the experimental group were better than those in the control group, but there was no statistical difference in the height at the end of treatment between the two groups (MD=4.03, 95%CI −0.01 to 8.06, P=0.05). (2) in terms of safety, the total incidence of adverse events in the experimental group (RR=2.10, 95%CI 1.48 to 2.99, P<0.01) was higher than that in the control group, among which the incidence of adverse events in the endocrine system and skin and subcutaneous tissue system was statistically different between the two groups (P<0.05), and the incidence of adverse events in the hepatobiliary system, kidney and urinary system, metabolism and nutrition, gastrointestinal system, musculoskeletal system, blood and lymph system, vascular and lymphatic system, and neuropsychiatric system was not statistically different between the two groups (P>0.05). ConclusionCurrent evidence shows that the third-generation non-steroidal AIs combined with rhGH can effectively improve the final height of children with short stature, but it may increase the incidence of adverse drug events. Limited by the quality and the follow-up period of the included studies, high-quality studies are still needed to demonstrate the above conclusions and further evaluate the long-term safety of AIs in children with short stature.
