Objective: To study the effect of community intervention on mental health of patients with type 2 diabetes mellitus (DM) Method:Two communities in a city of Shandong province were chosen as intervention community and control community respectively after an epidemiological investigation of diabetes mellitus in 1997 After four years intervention, a case-control study was done by assessing mental status with SAS (self-rating anxiety scale), SDS (self-rating depression scale) and SSRS (social support rating scale) Result:Compared with baseline levels, after intervention for 4 years, the SAS score, SDS score and SSRS score (including subject score and object score) of patients in intervention community improved significantly, while the counterparts of patients in control community had no improvement But patients in intervention community still had poorer results than health controls By adjustment of the potential confounding effect of age, sex and occupations, diabetes mellitus still had influence on anxiety, depression and social support with ORs of 1 41, 1 69 and 0 69 respectively Multivariable stepwise analysis showed that, suffering from other chronic diseases was risk factor for mental health of diabetes patients, and the higher the education level, the better results of intervention Conclusion:The DM community intervention program improves mental health of patients significantly, but patients still have poorer mental health than healthy control Education level and suffering from other chronic disease are main factors having influence on effects of the intervention

Objective To perform the epidemiological analysis of the developmental dysplasia hip(DDH) in Shigatse of Tibet in order to explore the correlation between the onset of DDH with some risk factors such as altitude and take targeted intervention measures to reduce the disability rate of DDH.Methods A total of 5900 children aged 0 to 14 year-old from different altitudes in Shigatse of Tibet were surveyed randomly from June 2013 to June 2014.SPSS 18.0 statistical software was used to analyze the correlation of the onset of DDH with residence altitude,production and living ways,binding method of the lower limbs,delivery situation and genetic factor.Results One hundred and ninety-one DDH cases were screened out,and the average incidence of DDH in Shigatse of Tibet was about 32.4‰,and unilateral was higher than bilateral,fight side(33 cases)∶left side(68 cases) =1.00∶ 2.06.The result of Pearson correlation analysis of the onset of DDH with residence altitude showed that there was significant correlation (r=0.820,P=0.046).The result of Spearman correlation analysis of the onset of DDH with production and living ways showed that there was significant correlation(r=0.530,P =0.048).The result of x2 test analysis of the onset of DDH with binding method of the double lower limbs and breech delivery showed that there was statistical significance (P=0.0017,0.0082).Conclusions The DDH incidence of children living in high altitude areas in Tibet has certain regional characteristics indicating that it has clear correlation with some environmental risk factors such as altitude,methods of the lower limbs binding,production and living ways and breech delivery,especially the bundled package of lower limbs is the main environmental risk factor of DDH.

AIM:To assess changes of tear film function in patients after pterygium excision combined with amniotic membrane transplantation.
METHODS:Totally 126 patients with pterygium excision with amniotic membrane transplantation from January 2011 to November 2013 were entered in the study. The tear breakup time ( BUT) , the Schirmer I test ( SⅠt) and tear ferning test ( TFT ) were elevated in the patients before and after pterygium excision combined with amniotic membrane transplantation. The examnation times were 1d before surgey, 1wk, 1, 2mo after surgery. Operation eyes were studied group, while opposite healthy eyes as control group.
RESULTS: Compared with the control group, BUT and TFT were significantly different in the eyes with pterygium (P<0. 05); However, no obvious difference was detected in the results of SⅠt (P>0. 05). The results of BUT and TFT at 1mo after surgery in study group were significantly better than 1wk (P<0. 05), while no significant difference compared with 2mo (P>0. 05); The tear film stability in the study group at 1wk after surgery was still inferior to the control group (P<0. 05) and there was no significant difference at 1, 2mo after surgery (P all>0. 05). SⅠt results did not differ between the different examination times(P>0. 05).
CONCLUSION:Tear film stability was broken in the eyes with pterygium. Pterygium excision combined with amniotic membrane transplantation can obviously restore the tear film function into normal state, and the tear film function could reach steady-state 1mo after surgery.

? AlM: To evaluate the clinical application of simply performing phacoemulsification or combining intravitreal Ranibizumab injection in the treatment of cataract combined with diabetic retinopathy.
?METHODS:Forty-six patients (46 eyes) were recruited in this study. All of the patients were non-proliferative diabetic retinopathy without significant macular edema. They were randomly divided into two groups, the control group simply performed phacoemulsification, while the study group performed intravitreal Ranibizumab injection and phacoemulsification. Observation of indicators included the condition of best corrected visual acuity (BCVA), intraocular pressure, macular retinal thickness and complication at preoperative and postoperative 1, 6mo.
? RESULTS: BCVA and macular retinal thickness of patients in two groups had no differences in the preoperative and postoperative 1mo. At postoperative 6mo, the BCVA of the study group was better than that in the control group, while its macular retinal thickness was thinner than that in the control group (P<0. 05). The ratio of macular edema ( central macular thickness was >60μm than that in control group) was 13. 0% eyes in the study group which was significantly lower than the control group (47. 8%;P = 0. 033). The complications was no significant differences in two groups and neither occurred severe complications.
?CONCLUSlON: lntravitreal Ranibizumab injection can reduce the development of macular edema and improve the BCVA after phacoemulsification.

Objective To analyze the clinical value of ultrasound and ultrasound-guided core needle biopsy ( UNB) in the evaluation of axillary lymph node metastasis for breast cancer.Methods A total of 454 cases of breast cancer treated between June 2008 and August 2014 at our hospital were retrospectively analyzed.UNB was performed on patients with abnormal ultrasonic diagnosis of axillary lymph nodes.Among them, 354 cases underwent neoadjuvant chemotherapy or endocrine therapy while 100 cases underwent surgery after UNB.The sensitivity, specificity, accuracy, positive predictive value, negative predictive value and false negative rate of ultrasound and UNB were evaluated.Results Among the 454 patients with abnormal axillary lymph nodes of ultrasound imaging, the metastasis rate with UNB was 70.9%,while the negative rate was 29.1%.Among the 100 cases who underwent surgery after UNB, the metastasis rate was 25% while the ultrasound imaging lymph node longitudinal and transversal ( L/T)≤1.5,the lymph node size>1 cm,and the metastasis rate was 92.3%(12/13).UNB showed that sensitivity was 64.1%, specificity 100%, accuracy 86%, positive predictive value 100%, negative predictive value 81.3%,and false negative rate was 18.7%.The results of UNB seemed consistent with those of postoperative pathological diagnosis, the Kappa value being 0.685.Based on 2 and 3 needles, the above mentioned 6 indices were 50% and 77.8%, 100% and 100%, 77.8% and 92.5%, 100% and 100%, 71.4% and 89.7%,and 28.6%and 10.3%, respectively.The Kappa value of UNB based on 3 needles was higher than on 2 needles (0.822 vs 0.526 ) .Conclusion Ultrasound is a valuable tool for detecting axillary lymph node metastasis in breast cancer.UNB can accurately determine the axillary lymph node metastasis status.UNB based on 3 needles shows a higher accuracy than on 2 needles.

UNLABELLEDOBJECTIVE To study the in vitro effect and mechanism of Ginkgo biloba Extract 50 (GBE50) for inhibiting beta-amyloid (Abeta)-induced oxidative stress in rats' hippocampal neurons.

METHODSThe primary hippocampal neurons were cultured in vitro and divided into 4 groups, i. e. the normal control group (Ctrl), the Abeta group, the propanediol control group (PDO), and the six GBE50 concentrations groups (5, 10, 25, 50, 100, and 200 microg/mL). Excepted the Ctrl group, neurons were induced to oxidative stress by 20 gmolLAbeta25-35. The MTT and fluorescent probes labeling were used to observe the effect of GBE50 with different concentrations on the cell viability and the generation of intracellular reactive oxygen species (ROS) in neurons. Furthermore, Western blot was used to detect the cytoplasmic/total cytochrome C (Cyto C) ratio and total intracytoplasmal Cyto C, and the effect of the expression of oxidative stress-related protein Cyto C and activated Caspase-3 in three GBE50 concentrations groups (25, 50, and 100 microg/mL).

RESULTSCompared with the Ctrl group, the cell vitality was obviously lowered and intracellular ROS generation significantly increased after induction of 20 micromol/L Abeta25-35 (both P < 0.05). Compared with the Abeta group, the cell vitality was evidently improved after treated with different GBE50 doses. Except for 10 microg/mL, the cell vitality could be obviously elevated along with increased drug concentrations (P < 0.05). Meanwhile, the intracellular ROS generation decreased significantly in each GBE50 dose groups (P < 0.05). Abeta could increase the cytoplasmic/total Cyto C ratio and enhance the activated Caspase-3 expression significantly (P < 0.05). Compared with the Abeta group, among the three concentrations of GBE50, the Cyto C ratio was obviously lowered in the 100 microg/mL GBE50 group (P < 0.05), and the expression of activated Caspase-3 significantly decreased in 50 microg/mL and 100 microg/mL GBE50 groups (P < 0.05).

CONCLUSIONS20 micromol/L Abeta25-35 could induce the generation of intracellular ROS in hippocampal neurons. GBE50 could inhibit Abeta induced intracellular oxidative stress of neurons through lowering the cytoplasmic/total Cyto C ratio and inhibiting the activation of apoptosis protein Caspase-3 expression.
