Objective To investigate incidence and onset of deep vein thrombosis (DVT) in elderly patients with hip fracture, and to evaluate the laboratory tests of plasma levels of D-Dimer, fibrinogen(FIB)and platelet(PLT) in diagnosing DVT. Methods From January, 2005 to December, 2006, 112 patients, 47 men and 65 women, aged 65 and over, were recruited into this study. Their mean age was 75.5 (range, 65 to 90) years. D-Dimer, FIB and PLT, as high specific fibrin degradation products, were detected via laboratory testing. The incidence, onset and distribution of DVT in these cases were observed. Univariate analysis was used to determine the associations between laboratory values and DVT. Influences of sex and type of hip fracture on the concentration of D-Dimer were studied as well. Results DVT was detected in 18 patients by means of B-mode ultrasonography and venography. The incidence rate of DVT in the elderly was 16. 1%. The onset of DVT took place between the second day and sixth day of hospitalization (average, 5.4 days), apparently earlier than the time of surgery (11. 6 days). Serum D-Dimer level was found significantly higher in the DVT group (P ＜ 0. 05) whereas levels of plasma FIB and PLT showed no significant influence on DVT(P ＞ 0. 05) . The D-Dirmer level was strongly influenced by type of fracture but not by sex.Conclusions Elderly patients with hip fracture have a high incidence of DVT. Since the onset of DVT usually happens before surgery, emergent operation is strongly indicated. A normal level of serum D-Dimer may be clinically significant in excluding the onset of DWT, but a simple rise in plasma D-Dimer level may not indicate DWT. The plasma levels of FIB and PLT may have no clinical significance in diagnosing DVT.D-Dimer level is not associated with sex of patients but with type of fracture.

OBJECTIVETo investigate the influence of the DNA integrity of optimized sperm on the embryonic development and clinical outcomes of in vitro fertilization and embryo transfer (IVF-ET).

METHODSThis study included 605 cycles of conventional IVF-ET for pure oviductal infertility performed from January 1, 2013 to December 31, 2014. On the day of retrieval, we examined the DNA integrity of the sperm using the sperm chromatin dispersion method. According to the ROC curve and Youden index, we grouped the cycles based on the sperm DNA fragmentation index (DFI) threshold value for predicting implantation failure, early miscarriage, and fertilization failure, followed by analysis of the correlation between DFI and the outcomes of IVF-ET.

RESULTSAccording to the DFI threshold values obtained, the 605 cycles fell into four groups (DFI value < 5%, 5-10%, 10-15%, and ≥ 15%). Statistically significant differences were observed among the four groups in the rates of fertilization, cleavage, high-quality embryo, implantation, clinical pregnancy, early miscarriage, and live birth (P < 0.05), but not in the rates of multiple pregnancy, premature birth, and low birth weight (P > 0.05). DFI was found to be correlated negatively with the rates of fertilization (r = -0.32, P < 0.01), cleavage (r = -0.19, P < 0.01), high-quality embryo (r = -0.40, P < 0.01), clinical pregnancy (r = -0.20, P < 0.01), and live birth (r = -0.09 P = 0.04), positively with the rate of early miscarriage (r = 0.23, P < 0.01), but not with the rates of multiple pregnancy (r = -0.01, P = 0.83), premature birth (r = 0.04, P = 0.54), and low birth weight (r = 0.03, P = 0.62).

CONCLUSIONThe DNA integrity of optimized sperm influences fertilization, embryonic development, early miscarriage, and live birth of IVF-ET, but its correlation with premature birth and low birth weight has to be further studied.

Objective To investigate the current situation of community health service requirements and health-seeking behaviors of the elderly in Yuzhong District of Chongqing City and analyse its mainly influencing factors,in order to provide references for further promoting hierarchical medical pattern.Methods A total of 410 elderly persons aged 60 year old or older treated in four community health service centers in Yuzhong district of Chongqing city in June 2015 were recruited by using multi-stage random sampling technique.The basic information about demography,cognitions and requirements of community health service,cost of health service and health-seeking behaviors were surveyed via questionnaire,and were analysed.Results A total of 402 effective questionnaires were returned,and the effective response rate was 98.05％.There were 76.37％ of elderly persons firstly selected community health service centers for disease treatment.The main factors affected health-seeking behaviors of the elderly were suffering from the coronary heart disease,the waiting time in community health service centers,the medical costs per month,facilities and environment of the community health service centers and whether to pay for health insurance.Conclusion Community health centers should make full use of their own advantages and convenience.It is necessary to provide characteristic services for the corresponding elderly patients,and increase the public health input.All of these are intended to raise the synthesized level of diagnosis and treatment in community health service centers,and change health-seeking behaviors of elderly patients fundamentally.

OBJECTIVETo investigate the values of the sperm deformity index (SDI), acrosome abnormity rate (AAR), and DNA fragmentation index (DFI) of optimized sperm in the prediction of fertilization failure (fertilization rate < 25%) in conventional in vitro fertilization (IVF).

METHODSWe selected 695 cycles of conventional IVF for pure oviductal infertility in this study, including 603 cycles of normal fertilization and 92 cycles of fertilization failure. On the day of oocyte retrieval, we examined sperm morphology, acrosome morphology, and DNA fragmentation using the Diff-Quik, PSA-FITC and SCD methods. We established the joint predictor (JP) by logistic equation and analyzed the values of different parameters in predicting fertilization failure with the receiver operating characteristic (ROC) curve.

RESULTSThe fertilization rate was negatively correlated with SDI (r = - 0.07; P = 0.03), AAR (r = -0.49; P < 0.01), and DFI (r = -0. 21; P < 0.01). The SDI, AAR, and DFI in the normal fertilization group were 1.24 ± 0.20, (7.75 ± 2.28)%, and (7.87 ± 3.15)%, and those in the fertilization failure group were 1.42 ± 0.15, (12.02 ± 3.06)%, and (13.32 ± 4.13)%, respectively, all with statistically significant differences between the two groups (P < 0.05). SDI, AAR, and DFI were all risk factors of fertilization failure ( OR = 2.68, 14.11, and 3.85; P = 0.01, < 0.01, and < 0.01). The areas under the ROC curves for SDI, AAR, DFI, and JP were 0.651 ± 0.033, 0.895 ± 0.019, 0.789 ± 0.022, and 0.915 ± 0.017, respectively. According to the Youden index, the optimal cut-off values of SDI, AAR, and DFI obtained for the prediction of fertilization failure were approximately 1.45, 10%, and 12%.

CONCLUSIONThe SDI, AAR and DFI of optimized sperm are closely associated with the fertilization rate, and all have the value for predicting fertilization failure in IVF. The AAR is more valuable than the other single predictors, but JP is more effective than the AAR.

Abstract: Molecular genetic map is a fundamental organizational tool for genomic research. However, a genetic linkage map for Bupleurum chinense DC. has not been developed. In this study, with the theory of pseudo-testcross, 96 F1 plants from an intraspecific cross of B. chinense were used as mapping populations. Twenty eight ISSR (inter-simple sequence repeat) primers and 44 SSR (simple sequence repeat) primers were used to detect the polymorphisms between the parental plants, and of them, 28 ISSRs and 14 SSRs were selected to analyze the F1 populations. The map consisted of 13 linkage groups which included 80 (72 ISSRs and 8 SSRs) loci, and covered 2 633.9 cM with an average density of 33.4 cM. All 13 linkage groups consisted of 2-31 loci ranging in length from 15.4-1295.7 cM. This map will provide a basis for studies on gene mapping, map-based cloning and maker-assisted selection of important traits in B. chinense.

· AIM: To discuss the cause and management of complications during the manual small incision cataract surgery (MSICS).combined with intraocular lens implant (MSICS-IOL) were done in 160 patietns with cataract. In this paper, we reviewed the clinical data of the intraoperative complications.injury, posterior capsule rupture, iris prolapse and hyphema, were mainly caused by inexpert skill and lacking of experience.techniques, careful operation could decrease the incidence of complications during MSICS operation. By proper management, the intraoperative complications could be solved satisfactorily.

AIM: To analyze the characteristics of neurological ophthalmology manifestation of patients with neurosyphilis. · METHODS: Retrospective and nonrandomized case analysis were used. Totally 22 cases of 39 eyes were included. They were 17 males and 5 females, aged from 34 to 65 years old. The average age were 49. 6 years old. ·RESULTS: The optic nerve atrophy presented in 11 cases of 22 eyes. One eye of them accompanied by left eye oculomotor nerve palsy;5 eyes in 3 cases expressed as optic neuritis acute phase;neuroretinitis appeared in 4 cases of 6 eyes; 1 case of 2 eyes expressed as chorioretinitis accompanied by optic disc edema; central retinal artery occlusion were found in 1 case of 1 eye. Argyll-Robertson pupil was as only manifestation in 2 cases of 3 eyes. In all cases, Argyll-Robertson pupil signs can be seen in 19 eyes. Treponema pallidum particle agglutination test ( TPPA) were positive in all 22 cases. Syphilis rapid plasma reactin test ( RPR ) were positive in 19 of 21 cases. All patients underwent lumbar puncture and cerebrospinal fluid were detected for RPR, cerebrospinal fluid protein, white blood cell count. Cerebrospinal fluid RPR were positive in 13 cases. Cerebrospinal fluid protein were greater than 450mg/L in 18 cases. Cerebrospinal fluid white blood cell count were greater than 5/mm3 in 13 cases. · CONCLUSION: Neurosyphilis involving neuro -ophthalmology often occurs in middle-aged men and subacute onset. Both eyes can suffered from optic nerve disease simultaneously or sequencely. A few can be expressed as other cranial nerve palsy, which may lead to misdiagnosis. Considering medical history, clinical manifestations, ophthalmic examination, serum and cerebrospinal fluid laboratory tests can improve the diagnostic rate.

Objective: To examine the causal relationship between food intake and atherosclerosis using two-sample Mendelian randomization (MR) approach, so as to provide the reference for the prevention of atherosclerosis. Methods: Data of 16 types of food (grains, vegetables, fruits, meats, etc.) and 4 types of atherosclerosis (coronary atherosclerosis, cerebral atherosclerosis, peripheral atherosclerosis and other atherosclerosis) was collected through IEU OpenGWAS database, with food data comprising approximately 500 000 subjects and 9 851 867 SNPs and atherosclerosis data comprising approximately 200 000 subjects and 16 380 447 SNPs. The causal relationship was analyzed using inverse-variance weighted (IVW) method with food as the exposure variable and atherosclerosis as the outcome variable. Sensitivity analysis was performed using funnel plots and leave-one-out. Results: Dried fruit intake was associated with decreased risks of peripheral atherosclerosis (OR=0.195, 95%CI: 0.082-0.466) and other atherosclerosis (OR=0.208, 95%CI: 0.095-0.452), and cheese intake was associated with decreased risk of peripheral atherosclerosis (OR=0.575, 95%CI: 0.380-0.870). Coffee intake was associated with increased risk of coronary atherosclerosis (OR=1.645, 95%CI: 1.099-2.462), and alcohol intake was associated with increased risk of other atherosclerosis (OR=1.269, 95%CI: 1.032-1.561). There was no statistically significant association between 16 types of food and cerebral atherosclerosis. No horizontal pleiotropy was found, no single SNP had significant impact on the overall estimated value, and the funnel plots did not show significant bias. Conclusion Dried fruit and cheese intake are protective factors for atherosclerosis, while coffee and alcohol intake are risk factors for atherosclerosis.
