Objective · To explore the relationship of adipose chemerin and its receptor chemerinR gene expression to obesity and type 2 diabetes mellitus. Methods · Twenty-four patients undergoing elective abdominal surgery were enrolled, and were divided into normal glucose regulation-normal weight group (NGR-NW), normal glucose regulation-overweight/obesity group (NGR-OW/OB), and type 2 diabetic overweight/obesity group (T2DMOW/OB) according to the body mass index (BMI). The levels of chemerin and chemerinR mRNA were detected by reverse transcription PCR (RT-PCR).Results · Compare to the NGR-NW group, the chemerin mRNA levels of abdominal subcutaneous and omental fat were significantly increased in the NGR-OW/OB and T2DM-OW/OB group (P<0.05). Correlation analysis showed that the chemerin mRNA levels of abdominal omental fat were positively correlated with BMI, fasting insulin (FINS), triglyceride and serum chemerin (r=0.577, r=0.561, r=0.472, r=0.623, P<0.05 for all). The chemerin mRNA levels of abdominal subcutaneous fat showed significant positive correlation with BMI, FINS and serum chemerin (r=0.692, r=0.513, r=0.497, P<0.05 for all). Conclusion · The chemerin mRNA levels of abdominal subcutaneous and omental fat were positively correlated with BMI, FINS and serum chemerin, suggesting that the chemerin gene may play a crucial role in the pathophysiological mechanism of obesity and type 2 diabetes.

Objective To study the therapeutic effect of combined antihuman IgG antibody with mitomycin(MMC) on human bladder cancer ceils and the primary mechanism. Methods In vitro an-tiproliferation effects of goat antihuman IgG antibody(Ab) with MMC, alone or together, on human bladder cancer cell line T24 were tested by MTT assay. Flow cytometer(FCM) was used to detect T24 cell apoptosis. Detections of activated caspase-3 and PARP[poly(ADP-ribose) polymerase] were carried out by Western blot analysis. In vivo antitumor effects of Ab of anti-human IgG with MMC were assessed using T24 xenograft in BALB/c nude mice model. Results The inhibitory rates of tumor growth of Ab, M MC and Ab+ MMC on T24 cell were (25.02±6.71)%, (32.31±6.46)% and (73.66±5.81)%, respectively. The rates of apoptotic cell of PBS, normal goat IgG, Ab, MMC, MMC±normal goat IgG, and MMC+Ab were 1.7%, 2.3%, 20.7%, 22.4%, 28.3% and 53.8%, respectively. Western blot shows Caspase-3 and PARP were cleaved in T24 cell during the course of apoptosis induced by Ab and MMC, and indicated that cell apoptosis was associated with caspase-3 and PARP activation. Under the treatment of normal goat IgG, Ab, MMC, and MMC+Ab, the in-hibitory rates of T24 xenografts in BALB/c nude mice were 2.31%, 12.73%, 36. 81%, and 50.51%, respectively. Histological examination demonstrated significant necrosis and apoptosis in the mice treated with alone MMC or Ab but no control goat IgG or PBS, in addition, HE displayed more extensive necrosis and apoptosis in the mice with MMC+Ab.Conclusion Antihuman IgG Ab with MMC has in vitro and in vivo inhibitory effects of human bladder cancer T24 , which are related to in-ducing cell apoptosis.

Objective To analyze the risk factors of retinopathy and nephropathy in hospitalized patients with type 2 diabetics. Methods 24 h-urinary albumin was measured in 2 338 patients with type 2 diabetic hospitalized from July, 2002 to Sep, 2008 in our hospital. All the subjects were divided into normalbuminuria group (NA) and diabetic nephropathy group (DN), the latter consisted of microalbuminuria group (MAU) and macroalbuminuria group (CAU). All the patients were divided into normal retina group (NR) and diabetic retinopathy group (DR), the latter consisted of background diabetic retinopathy group (BDR) and proliferative diabetic retinopathy group (PDR) according to fundus photography. Results (1) The percentages of DR and DN of this cohort were 28.8% and 28.7%, respectively.The percentage of DR and DN had no statistical difference between male and female (27.8% vs 30.0%;29.6% vs 27.6%, P>0.05). (2) The percentage of DR was 23.1%, 37.7% and 56.6% in NA, MAU and CAU group, respectively. There was significant difference among different albuminuria group (P<0.01). (3) The percentage of DN was 23.1%, 41.1% and 59.3% in NR, BDR and PDR group, respectively. There was significant difference among different DR group (P<0.01). (4) Combined with DN, diabetes duration, systolic pressure, hemoglobin A1C, triglyceride were independently associated with DR by Logistic regression analysis. Meanwhile, combined with DR, systolic pressure, hemoglobin A1C, and triglyceride were all independently associated with DN. Conclusions The onset and progression of microvascular complications in type 2 diabetic patiens are correlated with hemoglobin A1C and systolic pressure. Diabetic retinopathy is closely correlated with diabetic nephropathy.

Objective:To study the efficacy of transurethral plasmakinetic enucleation and resection of the prostate (TUERP) in the treatment of patients with small and medium-sized benign prostatic hyperplasia (BPH) (<60 ml).Methods:102 clinical cases of BPH (volume <60 ml) in Renmin Hospital of Wuhan University from October 2018 to July 2020 were retrospectively analyzed. All cases were treated with TUERP. The International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), postvoid residual volume (PVR) and prostate specific antigen (PSA) were compared before and after operation. Then the operation efficiency, intraoperative blood loss and postoperative complications incidence rate were analyzed.Results:102 patients with BPH successfully completed the operation. The operation time was 34-69(52.8±8.1)min. The change of hemoglobin concentration during the operation was (10.0±4.9)g/L. The volume of prostate resection was 16.5-42(27.8±5.9)g. The postoperative pathology showed that the prostate was nodular hyperplasia. Among 102 patients, 5 patients had transient stress urinary incontinence (4.90%), 4 patients had capsule perforation (3.93%), and 2 patients had urethral stricture (1.96%). There were significant differences in IPSS, Qmax, PVR and PSA with the comparison of preoperation and postoperation (six months) (all P<0.01). Conclusions:Transurethral plasmakinetic enucleation and resection of the prostate is safe and effective in the treatment of patients with small and medium-sized benign prostatic hyperplasia (<60 ml). It has the characteristics of high resection efficiency, less bleeding, low incidence of complications and exact curative effect.

OBJECTIVETo study the effects of astragalus membranaceus injection on sperm abnormality in Cd-induced rats.

METHODSThirty adult male Sprague-Dawley rats were divided into 5 groups: low concentration abstragalus membranaceus group(A1), high concentration astragalus membranaceus group(A2), cyclophosphamide group (CP), cadmium chloride group (Cd) and control group (C). Astragalus membranaceus injections 5 g/(kg.d) or 10 g/(kg.d) were given intraperitoneally to the rats of the A1, A2, CP and Cd groups. After 7 days, cadmium chloride(0.2 mg Cd/kg body weight) was administrated by intraperitoneal injection stimultaneously to the A1, A2 and Cd group rats. At 22 d after cadmium chloride induction, the rats were sacrificed and the testis coefficient, testicular sperm count, daily sperm production, epididymal sperm count and percentage of sperm abnorality were observed, and the testes and epididymides were studied pathologically.

RESULTSTestis coefficient, testicular sperm count, daily sperm production and epididymal sperm count in the A2 group [(5.68 +/- 1.19), (49.01 +/- 8.78) x 10(6)/g, (10.25 +/- 2.30) x 10(6)/(g.d), (47.51 +/- 22.51) x 10(6)/ml] increased significantly compared with those of the Cd group [(3.11 +/- 0.16), (37.59 +/- 10.63) x 10(6)/g, (5.31 +/- 0.32) x 10(6)/(g.d), (10.89 +/- 2.45) x 10(6)/ml] (P < 0.05 or P < 0.01). The percentage of sperm abnormality in the A2 group [(7.04 +/- 0.12)%] decreased significantly compared with that of the Cd group [(17.81 +/- 1.55)%] (P < 0.01).
