Objective To investigate the effects of uterine benign disease in perimenopausal women underwent simultaneous hysterectomy and bilateral salpingectomy on pelvic pseudocyst,ovarian function and symptoms of peri-menopausal period.Methods Nine hundred and ninety-three patients with benign uterine disease underwent hysterectomy of total or subtotal uterus were selected as our subjects,who hospitalized from Jan 2005 to Dec 2009.All patients were followed up for 36 months,and 235 patients were lost.The rest 758 patients included 438 patients underwent simultaneous hysterectomy and bilateral salpingectomy,who were served as study group,and 320 patients underwent only hysterectomy were served as control group.The occurrence of pelvic pseudocyst,symptoms of peri-menopausal period and the changes of serum sexual hormone were observed.Results (1) The rate of pelvic pseudocyst was 1.6％ (7/438) in study group,which was significantly lower than that in control group (4.4％ (14/320),x2 =10.962,P =0.026).(2) Follicle-stimulating hormone (FSH) in study group at 6 months and 12 months after surgery were (17.7 ±2.3) U/L and (26.8±5.1) U/L,higher than that in control group((12.3 ±2.9) U/L,(22.4 ± 3.2) U/L,t =-1.020,-1.162,P ＜ 0.05);FSH in study group(34.0 ± 6.8) U/L was lower than that in control group (39.1 ± 4.9) U/L at 36 months after surgery,and the difference was statistically significant (t =-1.209,P ＜ 0.05).At 3 months and 12 months after surgery,luteinizing hormone (LH) in study group were (14.0 ± 2.3) U/L and (26.2 ± 3.1) U/L,higher than that in control group ((11.7 ± 2.6) U/L,(21.6 ± 1.9) U/L; t =-1.421,-0.962,P ＜ 0.05).Estradiol in study group was (90 ± 23) pmol/L,lower than that in control group((110 ± 18) pmol/L) at 24 months after surgery(t =-1.502,P ＜0.05).(3) At 6 months after surgery,the rate of perimenopausl systems was 21.7％ (95/438) in study group,higher than that in control group (14.1％ (45/320),x2 =9.102,P =0.027).However,at 24 months after surgery,the rate of perimenopausal symptoms in control group was 60.6％ (194/320),higher than that in study group (47.0％ (206/438),x2 =7.620,P =0.039).Conclusion Simultaneous hysterectomy and bilateral salpingectomy could decrease the occurrence of pelvic pseudocyst and peri-menopausal symptoms nearly equivalent to that of hysterectomy only in patients with benign uterine diseases.

[ ABSTRACT] AIM:To study the influence of insulin resistance on fatty liver in the mice fed with high-fat diet (HFD).METHODS:Male 8-week-old C57BL/6J mice were randomly divided into HFD group (with 60% calories by high saturated fatty acid) and control group (with chow diet).The mice in both groups were fed for 12 weeks.The body weight, liver weight, serum triglyceride (TG) and total cholesterol (TC), and blood glucose and insulin levels were meas-ured.Hyperinsulinemic euglycemic clamp experiment was applied to reflect insulin sensitivity .The lipid deposition in the liver was analyzed by HE staining , Sudan IV staining and measurement of liver fat content .The phosphorylation levels of IRS1 and Akt, and the protein levels of SREBP-1 and FAS were determined by Western blot to reflect the activities of insu-lin signaling and lipid synthesis .RESULTS:Compared with control group , the body weight and liver weight were signifi-cantly increased in HFD group .TG and TC contents in serum and liver tissues were remarkably increased in HFD group . High-fat diet induced insulin resistance , as evidenced by increased serum insulin levels , reduced glucose infusion rate and decreases in IRS1 and Akt phosphorylation levels .In livers of HFD group, HE staining showed that the cytoplasm of hepa-tocytes was filled with vacuoles .Sudan IV staining also displayed that many different sizes of red lipid drops existed in the hepatocytes , and the protein levels of SREBP-1 and FAS were significantly increased .In primary normal hepatocytes with exogenous oleic acid intervention for 48 h, the phosphorylation levels of IRS 1 and Akt were reduced , and the protein ex-pression of SREBP-1 and FAS was significantly increased in a dose-dependent manner .CONCLUSION: Feeding with HFD leads to insulin resistance , resulting in activation of lipid synthesis and accumulation of lipid deposition in the liver , thus inducing fatty liver .

Objective:Discuss how the management of implantable medical consumables can be standard during the links of production, transportation, internal logistics of the hospital and the sector of using. Methods: In accordance with the relevant national laws and regulations, and long-term management practice and experience, and aiming at the specialty and high risk characteristics of implanting medical consumables, we apply information technique to regulate the standard operation of the whole medical supplies links (raw materials, processing of products, marketing, warehousing transportation, and the usage of the patients), therefore the roots can be traced back. The implanted medical supplies traceability standardized management needs to be explored. Results: Through the establishment of the traceability management process system of implanting medical supplies, the standard management mode of the medical supply technique will be attained. Even when the information is incomplete, we can retrieve and trace back quickly. Therefore, the goal of controlling the adverse events of medical implants, reducing medical risks can be achieved. Conclusion:the discussion above can be taken as a reference to the standardization of the management of implantable medical consumables.

Objective To prepare nanobubbles and analysis its application for enhanced ultrasound imaging of small-cell lung cancer (SCLC). Methods Nanobubbles were prepared using a thin-film hydration-sonication method. MTT assay was used to evaluate the cytotoxicity of the nanobubbles for SCLC H446 cell line. The contrast-enhanced ultrasound (CEUS) of xenografted SCLC tumors in 10 nude mice was performed using nanobubbles and micro-scale microbubbles, and compared with livers. The time-intensity curve (TIC) was obtained using the Gamma variate and the following parameters were calculated, including area under the curve, time to peak, arrival time, peak intensity, and half-peak time. Results Nanobubbles with spherical shape distributed homogeneously, without obvious aggregation, the mean diameters was (392.1 ±48.6) nm and average zeta potential was (-16.8 ±2.9) mV. The MTT results indicated that the nanobubbles had no obvious cytotoxicity toward H446 cell line within the concentrations used for in vivo ultrasound imaging with nanobubbles (5 μg/ml). CEUS with the nanobubbles showed significantly higher peak intensity, and half-peak time [(18.14 ±0.62) s, (141.55 ±8.21) s] in comparison with the micro-scale microbubbles [(14.82 ±0.51) s, (120.43 ±8.73) s] (P= 0.033, 0.040). There was no significant difference in time to arrival, area under the curve and time to peak (all P>0.05). Compared with livers, the nanobubbles in xenografted SCLC tumors showed significantly shorter time to peak, lower peak intensity and area under the curve, and higher half-peak time (all P < 0.05). There was no significant difference in time to arrival (P > 0.05). Conclusion Nanobubbles ultrasound enhanced contrast agent shows good stability and contrast-enhancement effect in vitro, and provides an experimental basis for targeting ultrasound imaging and therapeutics of SCLC.

Methods Forty-six patients ( 92 eyes) who underwent ICL/TICL implantations were enrolled in this study. The intraoperative and the postoperative complications in 6 months were observed,at the same time also the treatments and the outcomes were observed. Results None of the patients had a pupillary block. Only 8 eyes in all the patients had an elevated IOP after peripheral iridectomy ( PI) ,and 7 eyes after the ICL implantation,the highest IOP in which was 28 mmHg. No medication was given for treatment. In the YAG PI group,the incidence rate of iris bleeding and pigment dispersion were all higher than that in the YAG PI group (P<0. 05);2 crystalline lens of different patient were damaged intraoperation. Rotation of TICL was observed in 2 eyes. Only 2 individuals of all the patients in this study had complained visual disturbances,which was shadows and glare. Visual psychological change occurred in 1 patient. Conclusion The complications in the early time after ICL implantation for treat-ment of high myopia can prevent and control,the satisfaction of the patients is high.

Objective To probe into the treatment method of filter channel obstruction after trabeculectomy. Methods Filter channel obstruction occurred in 25 eyes within one month after trabeculectomy,and they were retrospectively analyzed. According to different parts of obstruction,they were divided into three types namely inner obstruction, middle obstruction and outer obstruction. Patients with inner ob-struction were given miosis, separation of the anterior synechia, and expansion of peripheral iris incision when necessary. Patienrts with mid-dle obstruction were given reconstruction of the trabecular incision. Patienrts with outer obstruction were given conjunctiva or sclera flap dis-section within 1 month afer trabeculectomy. Results Postoperative IOP ( intraocular pressure) decreased significantly compared with preop-erative IOP. The IOP stabilized at 13~21 mmHg in the fallowing 6~12 months after operation. Conclusion Taking appropriate measures could restore the filtration function within one month after trabeculectomy when the incision adhesion was not very close.

Objective To assess the renal protective effects of triptolide treatment in type 2 diabetic rats and its possible mechanisms.Methods Wistar rats were randomized to receive following approach control (n=7),dia- betic model without treatment (n=7) and diabetic group treated with triptolide[200 ?g/(kg?d),n=7].Plasma glucose (PG),serum creatinine (Scr),total cholesterin (TC),triglyeride (TG),kidney mass (KM),index number of kidney hypertrophy (KM/body mass,KM/BM),and 24 hours urinary albumin (24 h UAL) were determined. The protein expression of monocyte chemoattractant protein-1 (MCP-1),osteopontin (OPN) and ED-1 in renal tissue were determined by immunohistochemical technique.The mRNA expressions of MCP-1 and OPN in kidney tissue were assessed by reverse transcription-polymerase chain reaction (RT-PCR).Results Elevated 24 h UAL was markedly attenuated by triptolide treatment [24 h UAL,triptolide:2.32?0.29 vs diabetic model group:3.89? 0.51 mg/mgCr,P

AIM: To study effects of hyperbaric oxygen (HBO) and cyclosporin A (CsA) on the contents of active oxygens and nitric oxide (NO) in spleens of skin transplanted mice. METHODS: The donor mice BALB/C and receptor mice Cs7BL/6 were tested for skin transplantation. The HBO group mice were,treated with 99.2 % oxygen under 0.25 MPa for 1.5 hours, while CsA group mice were treated with CsA 0.5 rmg· kg- t· d- 1 by abdomen injection. After 14 days, the spleen were extracted the contents of malondialdehyde (MDA) and NO and the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH - PX), catalase (CAT) and NO synthases (NOS) were determined. RESULTS: (1) Compared with the control group, the transplantation group, HBO group and CsA group have markedly increased the content of MDA and the activities of GSH - PX and CAT; Compared with the transplantation group, the CsA group have markedly increased activity of SOD and reduced activities of GSH - PX and CAT; the HBO group have markedly reduced the activity of GSH - PX and increased the activities of CAT and SOD (P < 0.01 ). (2) Compared with the control group, the transplantation group have markedly increased the content of NO and the activity of NOS; Compared with the transplantation group, the HBO group have markedly increased the activity of NOS and reduced the content of NO ( P < 0.01 ); The content of NO and the activity of NOS in CsA group was not changed significantly. CONCLUSION: In the lymphocytes of the transplantation group, the peroxidation is intensified, and the content of NO and the activity of NOS increased. HBO and CsA may activate the systems of oxidation/antioxidation and NO/NOS in spleen, which may be related to their mechanism of inhibition rejection.
