This article analysed the clinical manifestations and endocrinological changes after pituitary apoplexy in 8 fulminant acromegalic patients. Their secretory functions of pituitary hGH after pituitary apoplexy could be divided into two groups: 1) those with decrease of the reserve of pituitary hGH secretion; 2) those with decrease of pituitary hypersecretion of hGH, but still having pituitary reserve. In the former group, with almost full destruction of the pituitary tumors, basal serum hGH levels decreased to normal and showed no response to stimulation; and the functions of other pituitary-target axes were also influenced; as a result, obvious metabolic changes were noted and replacement therapy was needed. In the latter group, because of partial destruction of the pituitary tumors, the decreased serum hGH levels were not suppressed to normal, but showed response to stimulus; most of the functions of other pituitary-target axes were normal; thus these patients should be followed up carefully to see if they would relapse.Meanwhile, there were 10 cases of typical acromegaly with normal serum hGH levels, though they had not received any kind of therapy before. These patients might be considered as the silent type of pituitary apoplexy. In this series, the incidence is 2.4% for the fulminant type and 3.0% for the silent type.

The response of serum hGH to TRH stimulation was studied in 33 normal adults and 35 patients with pituitary GH-secreting adenoma before and after treatment. The results showed that a net increment of serum hGH level of mor than 6.0 ng / ml together with an increment of serum hGH over basal level by more than 50% should be taken as a positive response.After treatment with bromocriptine over 5 weeks, most of the response of serum hGH to TRH remained unchanged regardless of whether the basal hGH level bad decreased or not. The disease was remittent or cured in those whose TRH response became negative after pituitary surgery and / or pituitary radiotherapy. A persistent positive or possibly positive response after treatment suggested that the disease remained active. Tne results indicated that this test could be used as a tumor marker.The possible mechanisms responsible for the positive TRH test in acromegaly were discussed.

The secretory profile of GH was generated by 15-30 minutes sampling in 10 normal adults and 4 acromegalic patients. The 15-and 20-min sampling revealed more GH pulses than 30-min sampling, but the average amplitude of GH pulses and the amount of GH secreted were of the same. The normal females had more GH pulses in morning after waking and in the postabsorptive period after dinner., All .4 acromegalic patients had no big GH peak after the first deep wave sieep. In 2 acromegalic patients who had a 24-hour GH profile measurement, the male patient with normal blood sugar level had more GH pulses, but the female patient with diabetes mellitus had only a few GH pulses. Our results showed that the autonomous GH-secreting tumor remains under hypothalamic control to some extent.

It takes 10 years for the pubertal development to be completed, which is the essential period for the normal growth of children. It is necessary to further study how the release of inhibion upstream of gonadotropin-releasing hormone (GnRH) neuron takes place and what the molecular nature of GnRH pulse generators is. Clinically, longitudinal surveys of clinical signs in large population as well as determinations of the ranges of normal and abnormal hormone values in both sexes during pubertal development are also mandatory, which will be helpful to the physicians in early treating pubertal disorders.

Cause-effect deduction is the basis of both natural and social sciences. Both wealthy knowledge and logical design are essential in obtaining the true causality among medical studies. Though association analysis provides important information for cause-effect deduction, it does not mean causality itself. Before the existence of the causality between two variables being identified, rigorous criteria must be followed. A number of indexes, such as the significance and the degree of the association, the dose-response relationship, the biology-based possibility, as well as the consistency and specificity, all should be examined very carefully. Clear verifiable hypotheses, rational selection of subjects, reliable experimental methods, appropriate statistical analysis and correct logical deductions, all are the integral parts that finally constitute a faithful deduction.

Journal of Clinical Endocrinology and Metabolism (JCEM), sponsored by U.S. Endocrine Society, is particularly appreciated by clinical endocrine doctors worldwide. It is intimately related to clinical practice while still catching up state of art research methods and recent discoveries and its creativity, novelty, scientific reliability, feasibility and readability are highly appraised. Compared to JCEM, our Chinese Journal of Endocrinology and Metabolism seems to be inadequate in certain aspects and needs to be improved in the future.

To study the effects of growth hormone on function of T lymphocytes. Methods: Tne expression plasmid PcDNA-GHcDNA was constructed,then the plasmids were transfected into Jurkat cells,on the other hand,Jurkat cells were treated with different doses ofrhGH, to investigate the effect of overexpression GH and rhGH on function of T lymphocytes. Results: Overexpression GH could increase the ex-pression of IL-2R(140％) and secretion of IL-2(160％) and IFN-γ( 198% ) in Jurkat cells after PHA activation,but these data were broughtdown by the treatment of GH antibody. rhGH could also enhancer the function of T lymphocytes after PHA activation. Conclusion: These resultssupport the idea that GH is an autocrine and paracrine factor, and can regulate the function of T lymphocytes.

This article reports the development of hyperosmolar hypernatremic hyperchloremic coma and acute renal failure in a male diabetic patient after recovery from hyperosmolar hypergly-cemic nonketonic coma, of which the cause is fluid retention in excess of urinary output due to the obstruction of lower urethra by diabetic neurogenic urinary bladder and hyper-plasia of prostate gland.By our experience each old diabetic man should be examined to confirm if he has neuro-genic urinary bladder and/or hyperplasia of prostate gland. Care should be taken to keep the balance of fluid intake and output provided that both of these conditions are present. The acute obstructive nephropathy can quickly ameliorate with release of the obstruction.

Objective:To study the effects of hormones on expression of GH gene in T lymphocyte.Methods:PGL2 GH Lucaluciferase reporter gene expression plasmid with hGH gene promotor was constructed and was transfected into Jurkat cells,Hormones were put into the medium of cell culture.Results:The expression of luciferase in Jurkat cells could be inhibited by different doses of hGH and GHRH (P

Objective To analyze the effect of traditional Chinese combined with Western medicine on the treatment of supracondylar fracture of humerus, and provide reference for clinical treatment.Methods122 patients with supracondylar fracture of humerus in hospital the affiliated hospital of traditional Chinese and western medicine;Zhejiang Chinese Medicine University from January 2015 to March 2016 were randomly divided into the observation group and the control group.The control group were given conventional fracture reduction, the observation group were given a new therapy of integrated traditional and western.Treatment outcome, quality of life changes and prognosis in the two groups were compared.ResultsThe excellent rate in the observation group (91.8%) was significantly higher than that in the control group (72.1%) (P<0.05).The fracture healing time in the observation group (4.1±1.1)months was significantly shorter than that in the control group (6.6±2.3) months (P<0.05).Before treatment, there was no significant difference in quality of life scores between the two groups;after treatment the overall health in the observation group (75.69±4.61), physiological function (77.62±4.19), pain (74.63±4.96), social function (76.84±4.28), mental health (76.12±4.18) scores were significantly higher than those overall health(62.74±4.36) in the control group, physiological function (64.51±4.12), pain (67.26±4.25), social function(68.72±4.13), mental health (65.97±4.23) (P<0.05).There were 2 cases with cubitus varus in the observation group, while 3 cases with elbow inversion in the control group.All patients were followed up for more than 6 months.There was no serious infection and abnormal bone development in the two groups.ConclusionIt can improve the treatment effect, reduce the pain of patients, promote the rapid recovery of the disease, improve the quality of life and prognosis, which traditional Chinese medicine combined with Western medicine was used in the treatment of humeral supracondylar fracture, it has the value of use.
