OBJECTIVETo study the expression of the receptor for advanced glycation end products (RAGE) and the inhibitory effect of advanced glycation end products (AGEs) on testosterone production in rat Leydig cells.

METHODSRat Leydig cells were primarily cultured and the expression of RAGE in the Leydig cells was detected by RT-PCR and immunofluorescence staining. The Leydig cells were treated with AGEs at the concentrations of 25, 50, 100 and 200 microg/ml, respectively, and the testosterone content was determined by ELISA.

RESULTSRT-PCR and immunofluorescence staining exhibited the expression of RAGE in the rat Leydig cells. AGEs remarkably suppressed hCG-induced testosterone production in the Leydig cells in a concentration-dependent manner in the 50, 100 and 200 microg/ml groups as compared with the control (P < 0.01).

CONCLUSIONRAGE exists in rat Leydig cells and AGEs can significantly inhibit the secretion of testosterone in primarily cultured rat Leydig cells.

Objective To explore the clinical efficacy of laparoscopic transabdominal preperitoneal (TAPP) hernia repair and risk factors affecting postoperative complications.Methods The retrospective casecontrol study was conducted.The clinical data of 595 patients who received laparoscopic TAPP hernia repair in the First Affiliated Hospital of Soochow University from February 2008 to August 2016 was collected.Operations were performed by the same doctors' team.Observation indicators:(1) surgical situations;(2) postoperative situations;(3) follow-up situations;(4) risk factors affecting complications after laparoscopic TAPP hernia repair.Follow-up using outpatient examination and telephone interview was performed to detect the recovery time of non-restricted activity,postoperative complications and hernia recurrence up to February 2017.Measurement data with normal distribution were represented as (x)±s.The univariate analysis and multivariate analysis were done using the chi-square test and Logistic regression model.Results (1) Surgical situations:595 patients underwent laparoscopic TAPP hernia repair using the heavy meshes.Overall operation time and overall volume of blood loss were (55±25) minutes and (7±5)mL,including operation time of (50±20)minutes in 502 unilateral hernias and operation time of (81 ± 29)minutes in 93 bilateral hernias.Of 595 patients,34 had incarcerated hernia,the contents of hernia:greater omentum,small intestine and sigmoid colon were detected in 21,11 and 2 patients,respectively,with an incarcerated time of 2-21 hours;4 with incarcerated hernia induced small intestinal necrosis received laparoscopy-assisted small intestinal resection ± anastomosis,1 with sigmoid colon necrosis received necrotic sigmoid canal resection ± sigmoidostomy and 29 received repair after the contents restoration of hernia.Operation time and volume of intraoperative blood loss in 34 patients with incarcerated hernia were (84 ± 39)minutes and (12±6) mL.Thirteen of 595 patients (10 with indirect hernia and 3 with direct hernia) had recurrent hernia,and operation time and volume of intraoperative blood loss were (75±-26)minutes and (10± 5)mL.(2) Postoperative situations:time to initial exsufflation of 595 patients was (19± 12)hours.Of 595 patients,590 took fluid diet at 6 hours postoperatively and 5 undergoing enterectomy took fluid diet at 24 hours postoperatively.The pain score at 1 day postoperatively and duration of hospital stay were respectively 2.5± 1.4 and (2.1± 1.9)days.(3) Follow-up situations:of 595 patients,593 recovered non-restricted activity at 2 weeks postoperatively and 2 didn't recover non-restricted activity at 2 weeks postoperatively.Of 595 patients,542 were followed up for 6-60 months,with a median time of 31 months.Fifty-seven,25,13 and 1 patients were respectively complicated with seroma,surgical pain,urinary retention and enteroparalysis,they were improved by symptomatic treatment,and the same patient can have multiple complications.There were no severe complications which needed surgical intervention,such as vascular injury,damnify of intestinal canal and poke hole hernia.Of 2 patients with recurrence of hernia,1 with right indirect hernia had recurrence of direct hernia and then received Lichtenstein tension-free hernia repair,and 1 received treatment in other hospital.(4) Risk factors affecting complications after laparoscopic TAPP hernia repair:results of univariate analysis showed that age,diameter of hernia sac,incarcerated hernia,recurrent hernia,operation time and volume of intraoperative blood loss were related factors affecting complications after laparoscopic TAPP hernia repair (x2 =6.657,55.296,44.305,5.253,117.461,100.722,P＜0.05).Results of multivariate analysis showed that diameter of hernia sac ≥ 4 cm,incarcerated hernia,operation time ≥ 100 minutes and volume of intraoperative blood loss ≥ 10 mL were independent risk factors affecting complications after laparoscopic TAPP hernia repair (OR =3.610,11.315,12.401,7.346,95％ confidence interval:2.009-6.486,3.579-35.772,5.408-28.437,3.739-14.434,P＜ 0.05).Conclusion Laparoscopic TAPP approach for inguinal hernia is safe and effective,and diameter of hernia sac ≥4 cm,incarcerated hernia,operation time ≥ 100 minutes and volume of intraoperative blood loss ≥ 10 mL are independent risk factors affecting complications after laparoscopic TAPP hernia repair.

Objective:To investigate the syndromes distribution in patients with dysfunctional uterine bleeding(DUB) related to kidney deficiency, and to provide the basis for standardizing the DUB syndrome differentiation of kidney deficiency. Methods: DUB Patients with kidney deficiency were chosen and accepted epidemical survey through the questionnaire, then the frequency and constituent ratio of each syndrome were calculated. Results: In 612 cases of DUB patients with kidney deficiency, there were 102 patients with simple syndromes covered 16.67%, and 510 patients with compound syndromes covered 83.33%. In patients with simple syndromes, the common syndromes were kidney-yin deficiency(45,44.12%) and kidney-qi deficiency(45,41.18%). And the syndromes of kidney-qi deficiency and kidney-yin deficiency were often respctively complicated with liver stagnation(68,11.09%; 113,18.43%), blood defi ciency(57,9.30%; 99,16.15%) and blood stasis(57,9.30%; 99,16.15%), the syndrome of kidney-yang deficiency usually complicated with spleen-qi deficiency(75,12.23%). The syndrome of kidney-qi deficiency(186,57.23%) was commonly-seen in the patients with ovular DUB, while the syndromes of kidney-qi(146,50.69%) and kidney-yin deficiency(111,38.54%) were frequently-seen in the patients with anovular DUB. Conclusion: In clinic, the compound syndromes were commonly seen in patients with DUB due to kidney deficiency, the complicated syndromes of kidney deficiency were liver stagnation, spleen-qi deficiency, blood deficiency and blood stasis..

OBJECTIVE: To examine the value of self-treatment for Posterior canal benign paroxysmal positional vertigo (PC-BPPV). The treatment effect was compared between patients treated with modified Epley in outpatient clinic combined with self treatment at home and patients treated by modified Epley alone. METHOD: A randomized controlled trial were carried out in the Department of Otolaryngology Head and Neck Surgery, the Affiliated Sixth People's Hospital of Shanghai Jiao Tong University from December 2012 to May 2013. 147 out of 150 patients with unilateral idiopathic BPPV-PSC were enrolled in follow-up. Among which, 73 patients were allocated in modified Epley-alone group and 74 were allocated in slef-treatment group. RESULT: The success rate was 53.4% in modified Epley-alone group vs 83.8% in self-treatment group (P < 0.01) after 1 week treatment. In the modified Epley-alone group,the success rate of hand repositioning group and chair-assisted repositioning group was 45.9% vs 61.1% (P > 0.05), the risk rate was 0.752, 95% CI (0.486 - 1.163). In the self-treatment group, the success rate of hand repositioning group and chair-assisted repositioning group was 87.5% vs 81.0% (P > 0.05), the risk rate was 1.081, 95% CI (0.888-1.316). Incidence rate of serious complications was 0% in the modified Epley-alone group and 1.3% in the self-treatment group (P > 0.05). CONCLUSION Complementary self-treatment with modified Epley maneuver treated PC-BPPV sooner and more effectively, Compared with modified Epley maneuver alone. And its incidence rate of serious complications didn't increase. Chair-assisted repositioning showed better result than hand repositioning alone, and self-treatment at home can reduce the effect of the gap. We found that complementary self-treatment with modified Epley maneuver had more benefits for patients with PC-BPPV.

OBJECTIVETo study the effects of Jisuikang (Chinese characters) on Nogo-NgR gene expression, and to explore the protective effects and mechanism of Jisuikang (Chinese characters) on spinal cord injury in rats.

METHODSOne hundred eighty female rats were randomly assigned to 6 groups(30 rats per group). Sham group: T10 lamina was resected only and spinal cord was untreated. Model group: spine cord injury (SCI) was created with a modified impinger of Allen's by impacting on the T10 spinal cord. Prednisolone group: Prednisolone (0.06 g/kg) was given by intragastric administration at a time interval of 24 hours after operation. The Jisuikang (Chinese characters) high, moderate and low dose groups: Jisuikang (Chinese characters) was supplied with different dose (50 g/kg, 25 g/kg, 12.5 g/kg) by intragastric administration in rats after operation,for the first time at 30 min after surgery. Animals were killed 3, 7, 14 days after surgery. The expression levels of Nogo-A and NgR were observed by Western Blot and Real-time PCR.

RESULTSThe expression of Nogo-A and NgR was at the basic level at all time points in sham group. Compared with model group, the protein expression levels of Nogo-A and NgR in sham, prednisolone, Jisuikang (Chinese characters) moderate dose groups were statistically significant at all time points (P < 0.05). No difference was found in Jisuikang (Chinese characters) high and low dose groups (P > 0.05). Three days after surgery, the mRNA levels of Nogo-A and NgR in treatment group were significantly lower than that in model group (P < 0.01); 7 days after surgery,Nogo-A and NgR mRNA expression were dramatically upregulated and peaked; 14 days after operation, the expression was decreased, but still significantly higher than that in other treatment groups (P < 0.01). Prednisolone and Jisuikang (Chinese characters) moderate dose groups showed the most significant effects among all groups,but there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONThe decoction Jisuikang (Chinese characters) can promote the nerve cell regeneration by regulating Nogo-A and NgR gene expression, activating Nogo- NgR signaling pathways after acute spinal cord injury.
