The results of different interventions administered in 118 cases with impaired fasting glucose (IFG) for 3 years were investigated. The rates of transformation of IFG to diabetes mellitus in metformin treatment groups and rosiglitazone treatment groups were significantly lower than that in life style intervention group. This study suggested that metformin or rosiglitazone treatment could effectively reduce transformation of IFG to diabetes as compared with life style intervention.

OBJECTIVETo observe and analyze the pathohistological characteristics of capsules which formed around the mammary prosthesis with different contents. And to provide the selective basis for ideal and safe prosthesis in clinical practice.

METHODS20 specimen of the capsules were taken from 20 cases who receive the operation of prothesis removal for different reasons. HE, Masson and Mallory staining were used to analyse the tissue structure and characteristics under the light microscope.

RESULTSThe common structure including the collagen fibers accumulation, inflammatory cells infiltration and the capillary hyperplasia were found in all specimen. A layer of squamous epithelium-like cell was detected in some specimen. The specific characteristics were also found in different capsules formed around different prosthesis. In the capsules around vegetable oil prosthesis, there was excessive collagen fiber accumulation, and the capsules were much thicker. In the PVP (polyvinylpyrolidone) prosthesis capsules, there was severe inflammatory cell infiltration, and the number of eosinophilic granulocyte increased obviously. In the silicone gel and saline prosthesis capsule, the collagen fibers were well-arranged and the inflammatory cells were much less. Synovial metaplasia was detected in two cases.

CONCLUSION1. The capsules form around the prosthesis in all cases after mammary augmentation. 2. There will be synovial metaplasis in some cases, for vegetable oil prosthesis, the collagen over-accumulated which lead the capsules become thicker and harder. So it is not a kind of ideal mammary prothesis. 4. The severe infiltration of the inflammatory cells especially the large quantity of eosinophilic granulocyte indicate the possibility of the delayed hypersensitive reaction mediated by eosinophilic granulocyte. Cautious attitude should be taken during application.

Objective To investigate the cell morphology and expression of 5-hydroxytryptamine transporter(5-HTT) in hippocampal CA1 region of depression rats induced by adolescent and post-adult stress,and to observe the inter-vention effect of modified Sini San (MSS). Methods One hundred and thirty-two Wistar rats were randomly divided into blank group,model group,JSS group,and fluoxetine group,33 rats in each group. And then the rats in each group were randomly subdivided into adolescent group, adult group, post-adult group acaccording to the age day, 11 rats in each subgroup. Age day 44,56 and 78 were used as the sampling time points for adolescent group,adult group,post-adult group respectively. Chronic unpredictable mild stress(CUMS)rat model was used. From day 21 to 44 and from day 57 to 78, the rats were modeled and given medication, but from day 44 to 55, the rats were fed normally. The rat general condition and body mass of various groups were observed,the cell morphology of hippocampal CA1 region was observed by hematoxylin-eosin (HE) staining , and the distribution of 5-hydroxytryptamine transporter (5-HTT)positive cells in CA1 region of hippocampus was observed by immunohistochemical staining. Results The general condition of the rats at different age stages in the model group was poor,while that in MSS group and fluoxetine group was improved obviously. The body mass of rats at different age stages in the model group was obviously decreased (P<0.01 compared with the blank group). After adulthood stage,the body mass of rats in model group, MSS group, and fluoxetine group was lower than that of the blank group(P < 0.01), but there was no difference between the 3 groups (P > 0.05). In aspect of cell morphological manifestation in hippocampal CA1 region, rats in the adolescent model group had more deeply-staining atrophy neurons, with unclear hyperchromatic nucleus and cytoplasm. The morphological manifestations in modeled rats at adult stage and post-adulthood stage showed progressive aggravation,manifested as a large amount of neurons stained deeply with unclear nucleus and cytoplasm, and a small amount of glial cells proliferated. Compared with the model group at the same stage,the neuronal atrophy and deeply staining decreased in fluoxetine group and MSS group. The average optical density value of 5-HTT expression in the model group was decreased significantly at the adult stage and after adulthood stage(P<0.05 or P<0.01 compared with the blank group). Compared with the model group, the average optical density value of 5-HTT expression in MSS group after adulthood stage, and in the fluoxetine group at the adult stage and after adulthood stage were increased (P<0.05 or P<0.01). Conclusion Rats suffering CUMS in adolescence presents depressive behavior, and post-adult stimulation can aggravates depression. 5-HTT expression in hippocampus may be an important pathway for MSS to achieve the therapeutic efficacy.

To optimize the belt drying process conditions optimization of Gardeniae Fructus extract from Reduning injection by Box-Behnken design-response surface methodology, on the basis of single factor experiment, a three-factor and three-level Box-Behnken experimental design was employed to optimize the drying technology of Gardeniae Fructus extract from Reduning injection. With drying temperature, drying time, feeding speed as independent variables and the content of geniposide as dependent variable, the experimental data were fitted to a second order polynomial equation, establishing the mathematical relationship between the content of geniposide and respective variables. With the experimental data analyzed by Design-Expert 8. 0. 6, the optimal drying parameter was as follows: the drying temperature was 98.5 degrees C , the drying time was 89 min, the feeding speed was 99.8 r x min(-1). Three verification experiments were taked under this technology and the measured average content of geniposide was 564. 108 mg x g(-1), which was close to the model prediction: 563. 307 mg x g(-1). According to the verification test, the Gardeniae Fructus belt drying process is steady and feasible. So single factor experiments combined with response surface method (RSM) could be used to optimize the drying technology of Reduning injection Gardenia extract.

Objective To explore the differences in the effectiveness of using different blood indicators individually,in combination,and for dynamic monitoring in the diagnosis,differential diagnosis,and prognosis of bacterial infections.Methods 1843 cases with infectious symptoms or signs from January 2015 to September 2022 at the People's Hospital of Yuxi City were selected as the case group,and 2298 uninfected individuals during the same period were selected as the control group.Blood indicators of the two groups were collected.Variables were grouped according to gender,age group,specimen type,etc.SPSS 24.0 and Medcalc 20.0 were used for statistical analysis.Results The individual diagnostic efficacy of various blood indicators for detecting infection ranges from 0.656 to 0.937.When used together,the efficacy ranges from 0.907 to 0.987.The efficacy of distinguishing between G+c and G-b in different specimens is as follows:when PCT is used alone in blood,the AUC is 0.875 for males and 0.769 for females.However,the individual diagnostic efficacy in male mucous secretions,sterile body fluids,and non-adult male sputum is all≤0.7.Yet,when used together,the efficacy is AUC(0.789,0.737,0.86)respectively.The dynamic monitoring of PCT,IL-6,CRP,WBC,and LAC in adult patients at 24 h,48 h,and 72 h after admission shows statistically significant differences in prognostic efficacy for G+c and G-b(P<0.05).Conclusions Blood indicators have a certain diagnostic value for determining whether there is a bacterial infection,and there are gender differences.The combined use of these indicators is more effective.The diagnostic value of using blood indicators alone or in combination for distinguishing between G+c and G-b in different types of specimens varies.The use of PCT alone in blood specimens is the most effective.For adult males,the combined use of body surface mucous secretions and sterile body fluids is most effective,while for underage males,the combined use of sputum is most effective.The combined use for females is not effective.Dynamic monitoring of PCT,CRP,IL-6,LAC,and WBC has a high value for evaluating the prognosis and therapeutic effect of infections.The evaluation of G+c infection is most effective at 24 hours for IL-6,and for G-b infection,it is most effective at 72 hours for PCT.

BACKGROUNDScreening for amblyopia at earliest is important for early treatment and better prognosis. This study aimed to evaluate the validity of uncorrected distant and near visual acuity (VA) and stereoacuity for screening amblyopia in grade-1 students in primary school in central China.

METHODSBy stratified cluster sampling, 3112 grade-1 students from 11 Anyang primary schools were selected for the study. All the participants underwent uncorrected distant and near VA, stereopsis test, cycloplegic refraction, best corrected VA (BCVA), cover test, and ocular movement examination. VA was measured with a logarithm of the minimum angle of resolution (logMAR) chart. Stereoacuity was measured with the Lang II stereo card and TNO test. Amblyopia was defined as the BCVA less than or equal to 0.1 logMAR units of any eye in the absence of significant pathological abnormalities. The sensitivity, specificity, and positive and negative predictive value of uncorrected VA and stereoacuity for amblyopia were analyzed.

RESULTSOut of the 3112 eligible students, 2893 (92.96%) completed the examinations. The average age of the students was (7.10 ± 0.41) years. Screened by distant VA with low cutoff (logMAR 0.1), high cutoff (logMAR 0.0), and near VA (logMAR 0.0), 31.64%, 73.18%, and 50.23% students were abnormal, respectively. Screened by stereopsis test, only 4.69% students were abnormal. Diagnosed by a senior pediatric ophthalmologist, 61 students had amblyopia. The sensitivities of distant VA with low/high cutoff and near VA were 92.31%, 100%, and 80.77%, respectively, whereas that of stereoacuity by TNO test was 15.38%. Simultaneous testing of either two of the three tests improved the sensitivity.

CONCLUSIONSDistant VA test of high cutoff alone displays a high sensitivity but a low specificity. Simultaneous testing of distant VA of low cutoff and stereoacuity is a better choice to balance between sensitivity and specificity.

Background: Metastatic colorectal cancer (mCRC) patients with progressive disease after all available standard therapies need new medication for further treatment. Famitinib is a small-molecule multikinase inhibitor, with promis-ing anticancer activities. This multicenter, randomized, double-blinded, placebo-controlled, phase II clinical trial was designed to evaluate the safety and efficacy of famitinib in mCRC. Methods: Famitinib or placebo was administered orally once daily. The primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), quality-of-life (QoL), and safety. Results: Between July 18, 2012 and Jan 22, 2014, a total of 167 patients were screened, and 154 patients were rand-omized in a 2:1 ratio to receive either famitinib (n = 99) or placebo (n = 55). The median PFS was 2.8 and 1.5 months in the famitinib and placebo groups (hazard ratio = 0.60, 95% confidence interval = 0.41–0.86, P = 0.004). The DCR was 59.8% and 31.4% (P = 0.002) and the ORR was 2.2% and 0.0% (P = 0.540) in the famitinib and placebo groups, respectively. The most frequent grade 3–4 adverse events were hypertension (11.1%), hand-foot syndrome (10.1%), thrombocytopenia (10.1%), and neutropenia (9.1%). Serious adverse events occurred in 11 (11.1%) patients in the famitinib group and 5 (9.1%) in the placebo group (P = 0.788). The median OS of the famitinib and placebo groups was 7.4 and 7.2 months (P = 0.657). Conclusion: Famitinib prolonged PFS in refractory mCRC patients with acceptable tolerability. Trial registration This study was registered on ClinicalTrials.gov (NCT01762293) and was orally presented in the 2015 ASCO-Gastrointestinal Symposium

OBJECTIVETo explore the mental health status of residents scattered living in Anxian after Wenchuan earthquake so as to provide scientific basis for further mental health intervention.

METHODSA face to face interview was conducted among the scattered residents with designed questionnaire, which had three parts of the physical and emotional reaction, the relax methods and the social care and supports expected. Two-stage probability proportional to size (PPS) sample method was performed to sample 2184 from 0.44 million scattered residents in Anxian. On the basis of statistical description, mental health of different characteristics groups was compared.

RESULTSThree main symptoms of posttraumatic stress disorders in 2184 residents (11.23+/-3.44) were higher than the 103 fire victims in Hunan in 2003 (10.06+/-3.26), three factor scores of SCL-90 (5.76+/-1.74) were higher than normal in 1998 repair mode (n=23 891) (4.72+/-1.44), and the statistical difference was observed (t=10.77, P<0.05; t=706.04, P<0.05). Comparing the mental health of different groups, some significant differences were found by age, gender and education background.

CONCLUSIONThe earthquake disaster brought prevalent physical and emotional reaction. Elderly people, female, junior students need mental intervention immediately. Therefore, strengthen the mental education and assistance (especially in high risk groups) would be of more significance.
