ObjectiveTo evaluate the safety and efficacy of biological meshes (human aceUular dermal matrix mesh) in single-stage repair of infected or contaminated abdominal abdominal wall defects and abdominal hernias. MethodsSeventeen patients with abdominal wall defects or abdominal hernias were enrolled. The wounds of all these patients were infected or contaminated due to the existence of enterocutaneous fistula or stoma, wound infection and synchronous colonic resection. The diagnosis included enterocutaeneous fistula 8 cases, incisional hernia 6 cases, incarcerated inguinal hernia 1 case and cylindrical abdominoperineal resection for rectal cancer for 2 cases. The sizes of abdominal defects ranged from 3 cm × 2 cm to 6 cm × 17 cm, and all the cases were repaired with human acellular dermal matrix mesh(RENOV(R)). Most of the patients were repaired with intraperitoneal onlay mesh technique( IPOM, for 12 cases), and other methods included Lichtenstein operation for 1 case, inlay repair for 2 cases and sublay for 2 cases. Results All the 17 patients recovered uneventfully. For 12 patients, the wounds were sutured at operation and only one case of delayed healing occurred due to fat liquefaction. For the other 5 patients, the wounds were left open and healed after vacuum assisted closure (VAC) therapy or wet- to- dry dressing changes. On follow up for 8.3 ±4.5 months ( 1 to 15 months), no occurrence of incisional hernia or recurrence was found. laxity of abdominal wall occurred in one case. A patient complained intermittent pain of the site of suture for mesh fixing two months after operation and the pain resolved spontaneously one month later. ConclusionsThe biological mesh, acellular dermal matrix mesh, could be used in single- stage repair of infected or contaminated abdominal wall defects safely and effectively, although the long-term outcome still needs further evaluation.

Objective:To explore associations of subclinical hypothyroidism (SCH) with endocrine metabolic characteristics in women with polycystic ovary syndrome (PCOS).Methods:A total of 321 women who were newly diagnosed as PCOS were recruited from two endocrine outpatient clinics.The diagnosis of PCOS was established according to the 2003 Rotterdam consensus criteria.Thyroid function was examined by chemiluminescent immunoassay.Patients who had normal free thyroxine (FT4) were divided into different SCH subgroups according to two thyroid stimulating hormone (TSH) cutoffpoints (4.2 and 2.5 mU/L).Endocrine metabolic characteristics in different subgroups were compared and analyzed.Results:In PCOS women with normal FT4,the patients with TSH ≥ 4.2 mU/L had higher prolactin (PRL),luteinizing hormone-to-follicle stimulating hormone ratio,and visceral adipose index (all P<0.05).There were trends toward an increase in triglyceride (P=0.085) and a decrease in high-density lipoprotein cholesterol (HDL-C) (P=0.060) in the patients with TSH ≥ 4.2 mU/L compared with that in the patients with TSH<4.2 mU/L.Also in PCOS women with normal FT4,the patients with TSH ≥ 2.5 mU/L had higher body mass index,PRL,triglyceride,visceral adipose index and lower HDL-C in comparison of that in the patients with TSH<2.5 mU/L (all P<0.05).Conclusion:SCH is associated with more severe endocrine abnormality,dyslipidemia,and visceral obesity in PCOS women.PCOS women with normal FT4 and endocrine metabolic characteristics are more prone to be different between the SCH group and the euthyroid group when setting 2.5 mU/L as a TSH cutoff for SCH,indicating that 2.5 mU/L is a good TSH cutoff for SCH in PCOS women.

Objective:To investigate the therapeutic clinical effect of laparoscopic high uterosacral ligament suspension (LHUS) combined with cervical amputation and vaginal sacrospinal ligament fixation (SSLF) in the treatment of prolapse of uterus in childbearing period.Methods:From October 2011 to December 2016, the clinical data of 78 patients with uterine prolapse above grade Ⅱ treated in Department of Gynecology, Jizhong Energy Fengfeng Group Hospital were retrospectively analyzed.According to different surgical methods, the patients were divided into LHUS group (40 cases) and SSLF group (38 cases). The operation time, intraoperative bleeding volume and hospital stay of the two groups were compared by independent sample t test.Before and 6 months after the operation, the prolapse quality of life questionnaire (P-QOL), pelvic organ prolapse/incontinence sexual function questionnaire-12 (PISQ-12) and pelvic floor distress inventory-short form 20 (PISQ-20) were used.PFDI-20 and pelvic floor impact questionnaire-short 7 (PFIQ-7) were used to evaluate patients′ quality of life, sexual function and pelvic floor function.Paired t test was used to compare the above scores before and 6 months after operation in the same group.Results:There were no significant differences in operation time, intraoperative bleeding volume and hospital stay between the two groups ( t value were 1.593, 1.203 and 0.535, , respectively, all P>0.05). The preoperative P-QOL, PISQ-12, PFDI-20, and PFIQ-7 scores of patients in the LHUS group were (55.4±11.1), (25.1±4.6), (15.0±4.9), (8.9±2.8) points, and (53.7±10.5), (23.9±3.7), (14.1±4.2), (9.2±3.0) in the SSLF group.There was no statistically significant difference in the indexes between the two groups before operation (t value were 0.694, 1.265, 0.869 and 0.457, respectively, all P>0.05). The scores of P-QOL, PISQ-12 at 6 months after operation in LHUS group((87.9±12.0), (39.1±6.1)) and SSLF group((81.3±11.7), (35.6±4.0)) were significantly higher than those before operation( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). The scores of P-QOL and PISQ-12 at 6 months after operation in the two groups were higher than those before operation((87.9±12.0), (39.1±6.1)), and the P-QOL score of LHUS group was higher than that of SSLF group 6 months after operation, the difference was statistically significant ( t value were 12.574, 11.589, 10.823 and 13.236, respectively, all P<0.001). At 6 months after operation, PFDI-20 and PFIQ-7 scores in LHUS group((2.1±0.3), (1.3±0.2) points) were significantly lower than before operation ( t value were=16.619 and, 17.123, all P<0.001). The PFDI-20 and PFIQ-7 scores in LIHUS group were lower than those in SSLF group((2.7±0.3), (1.9±0.2)) at 6 months after operation (t values were 10.096 and 13.073, respectively, all P<0.001). Conclusion:LHUS combined with cervical resection in the treatment of prolapsed uterine prolapse can effectively improve the quality of life, sexual function, and pelvic floor function.The effect is better than SSLF, which is worthy of clinical promotion.

Objective To observe the effects of constant light exposure on the obesity in high fat diet rats. Methods Thirty-two male SD rats were randomly divided into four groups:rats on a normal chow exposed to standard light-dark cycle ( group A) , rats on a normal chow exposed to constant light ( group B) , rats on a high fat diet exposed to standard light-dark cycle ( group C) , and rats on a high fat diet exposed to constant light ( group D) . Body weights and food intakes were recorded weekly throughout the 12-week study. Body weight, fat mass, visceral adipose tissue weight, intraperitoneal glucose tolerance test ( IPGTT) results, insulin resistance parameters, serum lipids and levels of interleukin 6 (IL-6), tumor necrosis factor-α(TNF-α) were compared among groups. Epididymal adipose tissues mRNA expression of circadian clock genes, i. e. clock, bmal1, rorα, rev-erbα, cry1, per1, and per2 were analyzed by realtime PCR. Results From the 9th week, body weights of rats in group D were significantly higher than those in group C (all P<0. 05). At the 12th week, area under curve of IPGTT (AUC-IPGTT) in groups B, C, and D were significantly higher than that in group A. AUC-IPGTT in group D was significantly higher than that in group C (all P<0.05). Compared with group C,asignificant increase in fat mass,visceral adipose tissue weight,homeostasis model assessment for insulin resistance, serum cholesterol, TNF-α levels were observed in group D ( all P<0. 05). And a significant decrease in quantitative insulin sensitivity check index ( QUICKI) and high density lipoprotein-cholesterol were observed in group D in comparison with group C (both P<0. 05). Circadian clock genes (clock, rorα, rev-erbα, cry1, per1) mRNA expressions in group B and D were significantly different from those in group A (all P<0. 05) . Expression of cry1 in group D was significantly higher than that in group C. In group C, rev-erbαmRNA expression was significantly down-regulated in comparison with group A (P<0. 05). Conclusion Constant light exposure exaggerates obesity, glycolipid metabolism abnormality, inflammation, and insulin resistance in high fat diet rats.

Objective:To investigate the serum level and significance of complement factor B (CFB) and complement factor D (CFD) in patients with type 2 diabetes mellitus (T2DM) and diabetic peripheral neuropathy (DPN).Methods:From October 2019 to October 2020, 110 patients with T2DM in the endocrinology department of Affiliated Hospital of Jining Medical College were divided into DPN group ( n=60) and simple T2DM group ( n=50) according to whether or not DPN was combined. In addition, 52 cases of physical examination population in the physical examination center in the same period were selected as the normal control group ( n=52). The serum levels of CFB, CFD and tumor necrosis factor-α (TNF-α) were measured by enzyme linked immunosorbent assay (ELISA). The correlation between CFB, CFD and clinical indexes was analyzed, and the influencing factors of DPN were analyzed by logistic regression. Results:The serum levels of CFB and CFD in DPN group were higher than those in T2DM group and normal control group [CFB: (845.43±101.10)μg/ml vs (792.19±116.59)μg/ml, (739.20±123.43)μg/ml, P<0.05], [CFD: (491.71±41.03)mg/L vs (467.58±45.16)mg/L, (445.16±50.47)mg/L, P<0. 05]. Pearson correlation analysis showed that the serum level of CFB was positively correlated with glycosylated hemoglobin (HbA 1c), fasting plasma glucose (FPG) and TNF-α (all P<0.05) and negatively correlated with triiodothyronine (FT3) and total bilirubin (TBIL) (all P<0.05). Serum CFD level was positively correlated with systolic blood pressure, HbA 1c, FPG and TNF-α (all P<0.05), but negatively correlated with FT3 and TBIL (all P<0.05). Logistic regression analysis showed that CFB and CFD were still influential factors for the occurrence and development of DPN after excluding confounding factors such as systolic blood pressure, HbA 1c, FPG, FT3, DBIL, TBIL and TNF-α. Conclusions:(1) Serum CFB and CFD levels were significantly increased in DPN patients, suggesting that CFB and CFD may be involved in the occurrence and development of DPN. (2) Serum TNF-α level was significantly increased in DPN patients, confirming the role of TNF-α in the pathogenesis of DPN.

The purpose was to optimize the vitrification for porcine embryos cryopreservation. Blastocyst/Morula (5-6th day-embryos) were collected from superovulated Bama mini-pigs (sows/gilts). We compared different cryopreservation methods, cryopreservation tools, thining of zona pellucida (ZP) and recipient breeds on the efficiency of porcine embryo cryopreservation. The results showed that: in embryo survival rate and blastocyst cell number, there were no significant differences between cryopreservation method I [embryos were vitrified by two step method with open pulled straw (OPS) and glass micropipette (GMP) in solution 1 (TCM199 + 20% FBS + 10% EG + 10% DMSO) for 3 min, and solution 2 (TCM199 + 20% FBS + 20% EG + 20% DMSO + 0.4 mol/L SUC) for 1 min, stored in liquid nitrogen] and method II[Blastocysts were cultured for 25 min in NCSU23 + 7.5 microg/mL cytochalasin B, centrifuged at approximately 13 000 xg for 12-13 min, and recovered back into pNCSU23. They were then equilibrated for 5 min in 2 mol/L ethylene glycol in pNCSU23, washed quickly in the vitrification medium, 8 mol/L ethylene glycol, 7% polyvinylpyrrolidone (PVP) in pNCSU23, loaded into OPS/GMP, and plunged into liquid nitrogen]. GMP vitrification method was more suitable and efficient than OPS method (P < 0.05) in embryo survival rate (83.8% vs 77.6%) and blastocyst cell number (53.1 vs 47.5) after thawing. Thining of ZP did not increase the survival rate, but significantly improved blastocyst cell number in the survival blastcysts (60.1 and 46, P < 0.01). Local pig breeds (Fengjing sows) were more suitable as recipients for embryo transfer of vitrified/warmed blastcysts, which can improve pregnant rate and embryo efficiency.
