Objective To investigate the relationship between ovary excision and serum levels of TNF ?, TGF ? 1. Methods Serum levels of TNF ? and TGF ? 1 in ovariectomized rats were measured by ELISA. Results The serum levels of TNF ? were increased〔(53 88?16 35)ng/L〕, but the TGF ? 1 were decreased 〔(6 78?0 75)?g/L〕 in ovariectomized rats when E 2 decreased compared with those of the Sham group( P

Objective　To study the distribution of insulin-like Growth Factors (IGFs) in liver、 spleen、kidney、thymus and supraadrenal glands of fetus from 16 to 24 weeks.Method　Using ABC immunohistochemistry. Results　 IGF-I positive cells were found in these organs during this period of fetal life, but the differences of number and reaction intensity of IGF-I positive cells appeared in different organs and individuals.Conclusion　These organs tissues can express IGF-I during fetal development and play paracrine and/or autocrine role in cellular proliferation and differentiation of these fetal tissue.

Polyunsaturated fatty acids (PUFA) was a functional component extracted from fish oil. The experiment results indicate that PUFA might inhibit platelet agglomeration induced by Adenosine diphosphate (ADP) in rabbit and rat. The results also suggested that PUFA has extent effect of anti-coagulation in mice. These effects are related with dosage of giving drug.

At present, the formal bariatric surgery approved by the American Society for Metabolic and Bariatric Surgery (ASMBS) includes adjustable gastric banding (AGB), sleeve gastrectomy (Sleeve gastrectomy, SG). ), Roux-en-Y gastric bypass (Roux-en-Y gastric bypass, RYGB), biliopancreatic diversion with duodenal switch (BPD-DS), mini gastric bypass (Mini-gastric bypass, MGB), single anastomosis gastric bypass (OAGB) and partial endoscopic surgery. According to the Chinese Society for Metabolic and Bariatric Surgery (CSMBS), the Chinese Obesity and Metabolic Surgery Database (COMES Database), and the Chinese Obesity and Metabolic Surgery Database (COMES Database), the Chinese Society for Metabolic and Bariatric Surgery (CSMBS) Chinese Obesity and Metabolic Surgery Collaborative, COMES Collaborative), Shanghai Weight Loss and Diabetes Surgery Data Management System, Shandong Province Weight Loss and Metabolic Surgery Case Registration System, Jiangsu Province Weight Loss and Metabolic Surgery Data Registration System, Great North China Weight Loss and Metabolic Surgery Statistics from the clinical data database and the Greater China Weight Loss and Metabolic Surgery Database. The domestically developed and approved bariatric surgery methods include RYGB, SG, MGB, OAGB, BPD-DS, AGB, combined sleeve gastrectomy (SG Plus), Jejunoileal Bypass (Jejunoileal Bypass, JJB), single stoma duodenal transposition (SADI-S), intragastric balloon (Balloon). However, there are still some irregular bariatric surgeries in China, which will cause some uncommon complications and bring great pain to patients. At the same time, it is also a huge challenge for regular bariatric surgeons who perform corrective surgeries. This article will review the revision surgery after bariatric surgery in China in the past 20 years, discusses a series of problems caused by non-standard bariatric surgery and the development of regular bariatric surgery.

In this paper, a carbon dioxide trans-critical refrigerating system which is different from a conventional subcritical refrigerating cycle was studied. The trans-critical carbon dioxide refrigerating systems are based on the Gustav Lorntzen cycle. Emphasis was focused on how to determine the optimal discharge pressure of compressor in CO2 trans-critical cycle. The factors related with the optimal discharge pressure were analyzed. A formula was developed based on cycle simulation, which could be used to predict the optimal discharge pressure of a basic CO2 trans-critical cycle. After further studies on CO2 trans-critical cycles with a regenerator or expander, two more formulas were also developed. These formulas could provide an access to improve the COP of CO2 trans-critical cycle.

Objective To observe multiple metabolic changes within one year after Roux-en-Y gastric bypass (RYGB) surgery in obese patients with type 2 diabetes mellitus, and to evaluate the index of the gastric bypass surgery and the determination of applicable population. Methods The clinical and laboratory data before and after surgery in 112 patients diagnosed as type 2 diabetes mellitus by RYGB were included in this study. According to BMI, these patients were divided into two groups: normal group (≤ 25kg/m2), and the overweight group (> 25 kg/m2). The physiologic and biochemical indexes of the patients were followed up at 1, 3, 6, 12 months, respectively. The statistical analysis was performed by SPSS17.0 software. Results Compared with the preoperative period, the levels of HbA1c and HOMA-IR in the postoperative period were significantly increased in the two groups. Principal component analysis showed that the postoperatively contributions of BMI and HbA1c in 6 months was bigger than that of the other indexes, while HOMA-β, HOMA-IR had larger contributions after 6-month postoperative period. Conclusion Various metabolic indexes in patients with type 2 diabetes improve significantly within one year after surgery, and the complete remission rate is gradually increased. The indexes including weight, blood glucose, serum lipids, HOMA-βand HOMA-IR in overweight and obese group have more significant improvements than those in normal group. Obese patients are more appropriate for the surgical treatment. The indexes, such as BMI, HbA1c,HOMA-βand HOMA-IR, should help to evaluate the operating effectiveness and preoperative indications.

Objective To study the concentration of anti-cyclic citrullinated peptide antibody (CCP),rheumatoid factor (RF),immunoglobulin (Ig) in synovial fluid and serum of patients with rheumatoid arthritis (RA),and the positive rate of anti-keratin antibodies (AKA) and anti-perinuclear factor (APF) were also measured.The aim was to explore the diagnostic value of these antibodies in synovial fluid for RA.Methods Thirty RA patients were collected,synovial fluid were withdrawn from the inflamed joints and peripheral blood were collected at the same time.Anti-CCP antibody,AKA,APF and RF were measured.The cut-off value of CCP in synovial fluid was determined through operating characteristic curve (ROC curves) analysis.The antibody levels in serum and synovial fluid were compared.Statistical analyses were performed using t test,and Pearson's correlation test.Results The cutoff value of CCP in RA synovial was higher,which was 29.00 U/ml,with the sensitivity of 87.00％ and specificity of 94.10％.There were significant differences in the concentration among anti-CCP antibody [(326±313) U/ml,(496±454) U/ml,t=-2.399,P＜0.05],IgG [(57±39) mg/L,(173±86) mg/L,t=-7.4792,P＜0.05),RF [(53±36) U/ml,(149±104) U/ml,t=-2.402,P＜0.05] in synovial and blood serum respectively in RA patients.Conchsion The diagnosis of RA is enhanced if anti-CCP antibodies,RF and IgG in synovial fluid are examined.They are supplementary to RA diagnosis and are helpful for clinical practice,especially for patient with very recent-onset RA.
