Objective To diagnose the intrauterine occupational disease by vaginal ultrasonography or hysteroscopy, and to evaluate the diagnostic values of these two methods. Methods One hundred and fifty patients were detected by vaginal ultrasonography and hysteroscopy from Jan 2004 to Dec 2004, and a total of 71 cases were confirmed intrauterine occupational disease. Tissue hysteroscopy or bioposy were performed during the hysterosocopy in order to analyse the tissue pathology. Results In these 71 patients, 47 were no less than 46 years old. Most of them had abnormal uterine bleeding.Thirty-three cases (46.48%) were suggested by vaginal ultrasonography, and 49 (69.01%) by hysteroscopy. Thirty-eight cases (53.52%) were in line with the pathological result.There were significant differences between vaginal ulterasonography and hysteroscopy in diagnosing the intrauterine occupational disease (P

Posterior capsular opacification (PCO) is the most common complication that leads to loss of vision after cataract surgery.Neodymium doped:Yttrium-Aluminum-Garnet (Nd:Yag) laser capsulotomy is a common treatment for PCO, but still associated with several complications.In the past decades, the prevention and treatment of PCO have always been a hot spot of research in ophthalmology.This review will address the advances in the prevention and treatment of PCO in the aspects of surgical techniques and types of intraocular lens (IOL).

Objective To investigate the clinical characteristics, treatment and prevention methods of severe complications during hysteroscopic procedures Methods From January 1995 to January 2001, seventeen cases with uterine perforation, heavy bleeding and fluid overload respectively were encountered during hysteroscopic procedures This analysis focuses on their diagnosis and clinical management as well as prevention methods Results Three cases with uterine perforation and seven with uncomplete perforation followed transcerivcal resection of myoma (TCRM), transcerivcal resection of adhension, transcerivcal resection of septum and transcerivcal removal of foreign body respectively, which were diagnosied by both B ultrasonography and laparoscopy and treated laparoscopically Four cases with heavey bleeding were encountered during TCRM Foley catheter was inserted into uterine cavity to stop the bleeding successfully Three cases with fluid overload were cured by diuretic agent and saline infusion There were no serious consequence happened Conclusions It is a potential high risk factor of resulting in complications that performing complicated procedures inside uterine cavity during hysteroscopic operations Pre treatment with gonadotropin releasing a and guiding with B ultrasound/ laparoscopy as well as controlling irrigation pessure are necessary for proventing above complications

AIM: To discuss the effects of preoperative vitreous cavity injection of ranibizumab on 25G minimally invasive vitreoretinal surgery (VRS) in patients with proliferative diabetic retinopathy(PDR).METHODS: From February 2013 to December 2015,74 patients with PDR received VRS (82 eyes) were retrospectively analyzed.Patients were divided into VRS + IVR group and VRS group according to preoperative VRS treatment.VRS+IVR group: preoperative injection of ranibizumab (10mg / mL) at 3-5d before operation;VRS group: VRS only.We recorded VRS operation time,filling situation,iatrogenic retinal hole and so on.RESULTS: The operation time and coagulation times of VRS+IVR group were significantly lower than VRS group.The two groups in operation time and coagulation times were statistically significant (all P<0.05).In the VRS+IVR group,the number of cases of iatrogenic retinal hole and the use of silicone oil were lower than those of VRS group,the difference between the two groups was statistically significant (P<0.05).While the use number of C3F8 and perfusion fluid were not statistically significant (P>0.05).In VRS-IVR group within 3mo after operation,4 eyes appeared to vitreous body hematocele,VRS group was 13 eyes,the difference was statistically significant (x2=4.966,P<0.05).CONCLUSION: PDR patients with 25G minimally invasive VRS with preoperative therapy can reduce postoperative ocular bleeding,rate of retinal injury and silicone oil filling,shorten the operation time,the incidence rate and improve the success rate of surgery and reduce eye bleeding,postoperative complications such as adhesion.

Results The contents of moisture, crude protein, total fat, total sugar and ash were 78.29%, 18.31%, 0.97%, 1.18% and 1.17%, respectively. The total amount of AA, EAA, NEAA and FTAA was 71.93%, 31.61%, 40.32% and 25.57%, respectively. 26 kinds of FA were identified. There were 6 kinds of SFA, 20 kinds of UFA. The contents of SFA, MUFA and PUFA were 26.26%, 29.61% and 39.91%, respectively. The contents of DG, TG, FFA, Cho and PL were 3.69%, 11.71%, 23.60%, 0.54% and 60.46%, respectively. Conclusion The crude protein and PUFA were high in muscle of Culter erythropterus. It was beneficial for health to eat it regularly.

OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.

METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.

RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.

CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Objective: To evaluate the association between autoimmune diseases (ADs) and thyroid dysfunction using a Mendelian randomization (MR) approach. Methods: Genetic predictors of hypothyroidism and hyperthyroidism were collected through the UK Biobank, including 337 159 individuals and 10 894 596 single nucleotide polymorphisms (SNPs). Genetic predictors of 6 ADs including systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), primary biliary cholangitis (PBC), and multiple sclerosis (MS) were collected through the GWAS Catalog database, including 14 267 individuals and 7 071 163 SNPs, 22 647 individuals and 99 962 SNPs, 24 840 individuals and 12 783 129 SNPs, 58 284 individuals and 13 108 512 SNPs, 13 239 individuals and 1 124 241 SNPs, and 38 589 individuals and 156 632 SNPs. MR analysis was performed using the inverse-variance weighted (IVW) method. The horizontal pleiotropy was assessed using the MR-Egger regression, and sensitivity analysis was conducted with the leave-one-out. Results: IVW results showed that a higher risk of hypothyroidism was associated with T1DM (OR=1.007, 95%CI: 1.003-1.011, P<0.05), SLE (OR=1.005, 95%CI: 1.002-1.009, P<0.05), and RA (OR=1.013, 95%CI: 1.009-1.016, P<0.05); a higher risk of hyperthyroidism was associated with T1DM (OR=1.002, 95%CI: 1.001-1.003, P<0.05) and SLE (OR=1.002, 95%CI: 1.001-1.003, P<0.05). Conclusions Genetically predicted ADs are associated with an increased risk of thyroid dysfunction. A higher risk of hypothyroidism is associated with T1DM, SLE and RA; a higher risk of hyperthyroidism is associated with T1DM and SLE.

Objective To provide the evidence for working out the strategies for library service by investigating the characteristics of Internet users' information behaviors in medical college and university library. Methods The In-ternet users' information behaviors in electronic reading room of medical college and university library were recorded using management software and analyzed using the SPSS. Results Medical undergraduates were the major readers in electronic reading room of medical college and university library. Their Internet information behaviors were charac-terized by information searching which accounted for 55. 19%. The use of foreign databases, especially PubMed, was more than that of domestic databases. The time of readers to search and use information was centralized in their working hours. Conclusion Library should help its readers to know how to search the databases, how to make full use of Internet resources, and how to improve their learning efficiency in order to make sure that the readers can ef-fectively search and use the Internet information.

Objective To investigate the association of risks related to maternal factors with the subsequent development of necrotizing enterocolitis (NEC) in very preterm infants and to determine whether the placental inflammatory lesions were also related to the NEC.Methods This retrospective cohort study examined newborns born at ＜ 32 weeks (n =180) between July 2006 and July 2015 and their mothers at our hospital,recorded the maternal age,body mass index (BMI),multiparity situation,and the usage of prenatal steroids or antibiotics.Medical records of eligible newborns and their mothers were reviewed.Maternal blood white blood cell and differential counts were measured at admission and the placentas were examined histologically after delivery.The primary outcome measure was NEC Bell Stage Ⅱ a.Bivariate analyses and multivariate logistic regression were used for the statistical analyses.Results NEC was diagnosed in 14 of 180 very preterm infants (7.8％),including 11 Stage Ⅱ and 3 Stage Ⅲ infants,and the overall mortality rate of these infants was 7.1％ (n =1).Multivariate regression analysis identified maternal neutrophil-to-lymphocyte ratio (OR =1.07,P =0.002),muhiparity (OR =3.39,P =0.013),and birth weight (OR =0.06,P =0.01) were significantly associated with an increased risk of NEC development.Neonatal neutrophil-to-lymphocyte ratio (NLR) as measured within 24 hours of birth (P =0.65) was not associated with NEC development.Clinical chorioamnionitis (P≥0.99) and histological chorioamnionitis (P =0.46) and funisitis (P =0.21) could not be used as significant predictors of NEC.Conslusions The development of NEC in very preterm infants is associated with the maternal NLR,parity,and birth weight,not with clinical and histological chorioamnionitis and funisitis.
