1.THE ACTION OF INSULIN-COUNTER HORMONES IN THE PATHOGENESIS OF DIABETES KETOACIDOSIS
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
Diabetic Ketoacidosis (DKA) is a condition biochemically characterized by the combination of hyperglycemia, hyperketonemia and acidemia. The extracellular concentration of glucose and ketone bodies in human body can respectively increase 5 and 20 times as more as usual, and the pH of arterial blood can decrease below 7.0. Accumulation of gluccse, ketone bodies and hydrogen must be due to the imbalance of the rate of production, ulilization, and excretion of these substance. In DKA, the metabolism of several hormones and substances is probably involved in the initiation and maintenance of ketone body over-production. At present, 14 patients with DKA have been investigated and it has been found that relative insulin deficiency appears to be necessary, and the excess production of growth hormone, glucagon and catecholamincs (the urine adrenaline and noradrenaline were measured) may be also important in the pathogenesis of DKA.
2.Influence of body mass index on function outcome after total knee replacement
Chinese Journal of Tissue Engineering Research 2010;14(26):4924-4928
BACKGROUND: Some studies have considered the influence of body mass index (BMI) on the function following total knee replacement (TKR), but the cases were few and follow-up time is short in most of them.OBJECTIVE: To analyze the function outcome influenced by BMI after TKR. METHODS: A total of 320 osteoarthritis patients who were admitted in Department of Bone and Joint at Peking University People's Hospital, were involved in this study. They all received primary knee joint patellar resurfacing, including both knees replacement in 200 case of 520 knees, left 219 and right 301. The involved 320 patients underwent primary TKR performed by a single surgeon with the same type of prosthesis (Scorpio posterior stable prosthesis). The patients were divided into four groups based on obesity (overweight group, BMI 25.1-27.0 kg/m2; obese group, BMI 27.1-30.0 kg/m2; morbidly obese group, BMI > 30 kg/m2; control group, BMI < 25 kg/m2). According to the Hospital for Special Surgery (HSS) rating scale, their knee score and functional scores were recorded before replacement and at follow-ups, as well as maximal range of flexion and extension, complications. Preoperative and postoperative assessment was based on the HSS score. RESULTS AND CONCLUSION: A total of 320 patients received clinical recheck at 28.3 months (range 12-46 months). Compared with control group, patients in overweight, obese and morbidly obese groups had lower preoperative functional score (P < 0.05), but knee scores were not significantly different for any patient group. The postoperative mean HSS score of all the groups rose significantly at the last follow-up. These differences were not statistically significant among groups (P > 0.05). The rate of perioperative complications was significantly higher in the obese and morbidly obese patients (P < 0.05). Of the 181 knees in obese and morbidly obese patients, 14 knees (9.2%) had a wound complication, 1 knee (0.5%) had an infection, and 2 knees (1.3%) had an avulsion of the medial collateral ligament. The infected case developed within ten weeks after the operation, and was associated with a wound complication. Among 266 knees in the overweight patients, 6 knees (2.3%) had a wound complication. There was 1 knee (1%) of the 81 knees in the control group had a wound complication. No death or pulmonary embolism cases were observed in perioperative period. It is suggested that BMI has no obvious influence on the functional outcome following TKR in the short-term.

6.A Study on the Treatment of Ketoacidosis in Diabetes Mellitus-Analysis of 100 Cases
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
Of 807 Cases of Diabetes mellitus, 100 were ketoacidosis with or with-ot coma(40 Cases among them with coma), 55 were males, 45 females. Therange of age was 5 to 76 years. There were 39 cases of ketonemia with ju-venile diabetes, and the incidence was 29. 5 per cent of 137 cases. 61 werefound to have ketonemia with adult dialetes, the incidence being 10. 2 percent of 594 cases. Blood glucose level was 166. 7 to 1000mg/dl. The mostcommon precipitating causcs of ketonemia were infection and the dis-continue of insulin treatment(58 per cent). According to the dosage of insu-lin, our patients were divided into two groups. One was a small dosagegroup(the total mean dose 25. 5 ? 3. 1 u), the other was a large dosage group(the first 8 hours' mean dose 121. 67 ? 102u, the fitst 24 hours' mean dose206. 62 ? 18. 01) There were on death and severe complications of insulintherapy in the small dosage group, but 13 (16 per cent) were died in thelarge dosage group, in which there took place such complications as hypo-kele mia(11 per cent), hypoglycemia (26 per cent) and encephaledema (3. 8per cent). Also, the negative acetone bodies occured faster in the smalldosage group. For this reason, we consider the effect of the treatment inthe small dosage group was better. Recently, we have controlled alkelidosage more strictly than before. 100-200ml of 4% Bicarbonate was givento the patient if the blood CO_2 combinedpower was lower than 20 Vol pe,

The sensitivity of ABC-ELISA is compared with that of standard ELISA; Its reliability is proven by the methods of detecting TSAb with FRTL-5. TRAb is detected by ABC-ELISA in 91% of untreated Graves'. TRAb is detected by Standard ELISA in 70% of untreated Graves'. The results of ABC-ELISA in 26 untreated Graves' are equal to that of the method of detecting TSAb with FRTL-5. Therefore, we consider that ABC-ELISA is a sensitive, reproducible, convenient method applicable to clinical practice.
8.THE CLINICAL OBSERVATION OF THE PATHOGENITIC FACTORS OF HYPERTENSION IN PATIENTS WITH NIDDM
Journal of Xi'an Jiaotong University(Medical Sciences) 1981;0(03):-
A part of pathogenetic factors of hypertensionin twenty--seven patients with hypertensive NIDDM (group 1) were observed. The control groupsincluded non-hypertensive NIDDM (group 2, n=46 ), primary hypertension (group 3, n= 15) andhealthy persons (group 4, n= 15). The oral glu-cose tolerance test (OGTT), insulin releasing test(IRT ), atrial natriuretic peptide (ANP), an-giotensin I (ATI), aldosterone (ALD), wholeblood volume and urine protein were measured.The results showed that the plasma insulin andsodium levels and the whole blood volume weresignificantly higher in group 1 than those in con-trol group 2, the ANP level was rather lower than that in control group 4. Although the results werecorresponded with the theory that the circulatinghyperinsulinemia may lead to sodium retention andinhibited an adequate ANP stimulation by sodiumchallenge which turn to hypertension, nonhyper-tensive NIDDM patients (group 2) also have thesame findinge. So the retention of sodium and wa-ter can't be used to explain the mechanism of hy-pertension in NIDDM patients, the other patho-genetic factors especialy the factors related to thehyperinsulinemia such as PGE and PGI need to beinvestigated futher.
9.Molecular mechanisms and biology significance of polysaccharide recognition by the immune system
Chinese Journal of Immunology 1985;0(01):-
As monosaccharide polymers,polysaccharides are widely distributed in nature,they are found in microorganisms,plants and animal cells and tissues.Glycosylation is of importance to maintain the structural stability and biological activity of protein molecules in eukaryotic cells.Polysaccharides represent the most important antigens recognized by immune system.The innate immune system senses invading microbes via their pathogen-associated molecular patterns,using pattern-recognition receptors on the surface of innate immune cells,many of which are polysaccharides uniquely expressed in certain microorganisms.Polysaccharides can also be processed intracellularly and presented to ??-T cells by MHC molecules.Polysaccharides can activate B lymphocytes,with or without T cell help,and induce production of specific antibodies.Amongst the polysaccharide-specific antibodies in human sera,some are products of adaptive humoral responses against microbial infection and others autoantibodies to glycan epitopes of host cells.Patients with autoimmune disorders tend to have higher titers of antibodies against various glycans.Immune clearance of senescence cells depends on the recognition of altered glycan epitopes on cell surface.Modification of glycan epitopes on tumour cell surface is at least partially responsible for activating antitumor immunity.Specific recognition of polysaccharides by the immune system is of importance to immunological defence,autoimmunity,anti-tumour immunity and immunological homeostasis,it will be the new focus of immunology research in the near future.
