Objective: To investigate the prevalence of affective disorder in Kunming City. Methods: A rep-resentative sample of the Kunming general population composed of 5033 individuals aged 15 years and older was se-lecteed randomly by the method of probability proportional to size (PPS), and then was interviewed with the World Health Organization Composite International Diagnostic Interview Version 2.1 (CIDI, version 2.1).The preva-lence of affective disorder was investigated. And the relative factors, onset age and comorbid were also analyzed. Results: The 30-duy prevalence of affective disorder was 0.98%, the 12-month prevalence was 1.22%,and the lifetime prevalence was 1.89%. The results of the single factor analysis showed that the urban residents, the persons who divorced, limited divorced or lost one's spouse, and the unemployed or the higher educated were more vulnerable to depression. The results of the multifactor analysis showed that the rural residents and the males were protective factors to affective disorder. Different subunits of affective disorder had different onset ages. The onset age of 90% bipolar disorder patients was before 25 years old. The patients before 50 years old was risky to dysthy-mia. The patients with major depression had a lifetime risk of onset. Anxiety disorder and pain disorder would in-crease the risk of affective disorder. Conclusion: The findings show that the prevalence of the affective disorder is lower than the same kind survey abroad while it is close to the domestic's. More attention and intervention should been given to the urban population, the females, the singles, the unemployed, and the higher educationed.

Objective To study the iodine nutritional status of population living in Tibetan pastoral areas,in order to provide a scientific basis for prevention and control of iodine deficiency disorders.Methods Drinking water samples were collected to test iodine content in agricultural town(Kajiaman) and pastoral area(Zuogaiduoma town) of Hezuo in Gannan Tibetan autonomous prefecture.Thirty of child-bearing age,pregnant and breastfeeding women were selected,respectively,and 90 male adults aged 20-50 from these families(1 from each family) and 90 children aged 8-10 (30 people in each age group) from local schools were randomly sampled at the same time,and urinary iodine (UI) was measured randomly.Edible salt and main food samples were collected to test iodine content from the 10 families of the three types of women,respectively,and they were asked to recall its family intake of food species in the past 24 h excluding spices.The water iodine was determined using arseniccerium redox method (GB/T 5750.1-2006) ; UI with ammonium persulfate digestion-arsenic cerium catalytic spectrophotometric method (WS/T 107-2006) ; salt iodine used direct determination method(GB/T 13025.7-1999); and food iodine with alkali the gray arsenic cerium contact colorimetry.All these work were done in May,2011.Results The average of water iodine was (1.63 ± 0.14)μg/L in agricultural areas and (2.08 ±1.90)μg/Lin pastoral areas of the 10 water samples tested,respectively.The median urinary iodine(MUI) among women of pregnant,lactating and child-bearing age,male adults and children was 141.99,126.65,253.33,258.07,191.0μg/L,respectively,in agricultural areas and 137.26,97.36,126.16,159.48,285.07 μg/L,respectively,in pastoral areas.The difference of MUI in lactating,male adults and children between pastoral and agricultural areas was statistically significant.The proportion of UI ＜ 50 μg/L was less than 20％,and ＜ 100 μg/L was less than 50％ among all population except lactating woman and pregnant women in pastoral areas.The iodized salt coverage rate was 100％(30/30) in agricultural areas and 90％(27/30) in pastoral areas,and the salt iodine was (32.1 ± 7.8)mg/kg in agricultural areas and (32.3 ± 6.0)mg/kg in pastoral areas,respectively.The food structure in agricultural areas was mainly potato,naked oat fruit,cabbage and so on,the average dietary iodine content was 285.7 μg/kg,and in pastoral areas was mainly chow mein,wheat flour,ghee,yogurt,barley and so on,the average dietary iodine content was 51.1 μg/kg.Conclusions There is no iodine deficiency in general in the population in Tibetan areas with low water iodine.However,iodine nutrition of pregnant women can not be guaranteed.It is recommended that classified guidance measures be taken to ensure the sustainable elimination of iodine deficiency disorders in the Tibetan minority areas.

Objective To explore the association of resting heart rate (RHR) and coronary artery lesions with left ventricular function in coronary heart disease for secondary prevention of this disorder.Methods We collected data on 239 patients with coronary heart disease confirmed by coronary angiography or coronary CTA examination in Military General Hospital of Guangzhou Command from January 2016 to August 2017.The clinical data and results of selective coronary angiography were studied.According to baseline RHR,the patients were divided into 4 groups with RHR ＜ 60 min (group A,32 cases),60 to 69 min (group B,60 cases),70 to 79 min (group C,68 cases),and ≥ 80 min (group D,79 cases) for analyzing the relationship of RHR with coronary artery lesions and left ventriculai function,and investigating the association of RHR and left ventricular indexes with severity of coronary artery lesions by ordinal Logistic regression analysis.Results Coronary artery lesions differed significantly among the 4 groups (P ＜ 0.05).the difference of LVDs、LVDd、LAs and EF was statistically significant (P ＜ 0.05),but there was no difference of LAd (P ＞ 0.05).Smoking、diabetes、the index of EF and LVDs were found to correlate with the degree of coronary lesion by Logistic regression analysis (P ＜ 0.05).Conclusions RHR can affect the severity of coronary artery disease and left ventricular function in patients with coronary heart disease,and good control of RHR is beneficial for the prognosis of patients with coronary heart disease.Smoking、diabetes、the index of EF and LVDs were found to correlate with the degree of coronary lesion by Logistic regression analysis (P ＜ 0.05).

OBJECTIVETo observe the effect of Xinfeng Capsule (XFC) on ankylosing spondylitis (AS) patients' symptoms and signs, serum immunoglobulin levels, peripheral blood lymphocyte autophagy protein, autophagy gene, and to explore its mechanism.

METHODSTotally 59 AS patients were assigned to the treatment group (39 cases) and the control group (20 cases) according to random digit table. Patients in the treatment group received XFC, 0.5 g each pill, three pills each time, 3 times per day, while those in the control group received sulfasalazine (SASP), 0.25 g per tablet, 4 tablets each time, twice per day. Three months consisted of one therapeutic course. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) were statistically calculated. Serum immunoglobulins (IgG1, IgG2, IgG3, IgG4, IgA , SIgA, and IgM) were detected using ELISA. Changes of Beclin1, LC3-II, phosphatidylinositol 3-kinase (PI3K), Akt, the mammalian target of rapamycin (mTOR) were detected using Western blot. Serum autophagy related genes such as Atg1, Atg5, Atg12, Atg13, and Atg17 were detected using the polymerase chain reaction (PCR). The correlation between immunoglobulin subtypes and autophagy gene in AS patients using Spearman correlation.

RESULTSCompared with before treatment, BASDAI, IgG1, lgG3, and IgA decreased (P < 0.01); PI3K, Akt, and mTOR protein expressions decreased (P < 0.01); ATG1, ATG12, ATG13, and ATG17 mRNA expressions decreased, ATG5 mRNA expression increased (P < 0.01) in the treatment group. But BASDAI, IgG1, and IgA levels decreased (P < 0.05, P < 0.01); PI3K, Akt, and mTOR protein expressions decreased (P < 0.05); ATG1 and ATG13 mRNA expressions decreased (P < 0.05, P < 0.01) in the control group. Compared with the control group, BASDAI, IgG1, and IgA levels decreased (P < 0.05); PI3K, Akt, mTOR protein expressions decreased (P < 0.01); ATG12 and ATG17 mRNA expression decreased, ATG5 mRNA expression increased (P < 0.01) in the XFC group. Correlation analysis showed AS patients' IgG1, IgG2, IgG3, IgA, SIgA, IgM had negative correlation with ATG17; IgG4 and ATG17 were positively correlated (P < 0.05, P < 0.01).

CONCLUSIONXFC could elevate clinical efficacy of AS patients and enhance their autophagy, which might be achieved by acting on PI3K/Akt/mTOR signal, affecting autophagy gene and autophagy protein expression, taking part in the regulation of proliferation and differentiation of lymphocyte B, and strengthen humoral immunity.

The effect of antisense oligonucleotide (ASODN) targeting survivin on renal cell carcinoma (RCC) apoptosis, proliferation and sensitivity to chemotherapeutic drugs was investigated. Antisense oligonucleotide targeting survivin was designed and composed. The cDNA of survivin was transfected into RCC cell lines ACHN and 769-P, respectively. They were both cultured in normal condition. After transfection, ACHN and 769-P cell lines were cultured in a 6-well culture plate. The cultured cells were divided into 6 groups. Twenty-four h after transfection, survivin protein expression was detected by Western blot. Apoptotic index (AI) and proliferative index (PI) were examined by flow cytometry. Rate of inhibition (IR) by chemotherapeutic drugs was determined by the colorimetric MTT cell viability/proliferation assay. The results showed AI and IR of chemotherapeutic drugs in ASODN groups were significantly higher than those in the groups without ASODN. There were statistical differences between ASODN groups and control groups (P< 0.05), but there was no difference among control groups (P>0.05). The PI in the ASODN groups was significantly lower than that in the control groups with the difference being statistically significant (P<0.05). In addition, there were no differences among control groups. It was concluded that the expression of survivin could be down-regulated in 2 cell lines after ASODN transfection. Antisense oligonucleotide targeting survivin could induce RCC apoptosis, inhibit cell proliferation and sensitize RCC to chemotherapy.

OBJECTIVE: To observe the changes of pulmonary function and Notch signaling pathway of lung tissues in adjuvant-induced arthritis rats, and to investigate the mechanism of reduced lung function. METHODS: A total of 30 rats were randomly divided into a normal group and a model group. Rats in the model group were induced to establish the adjuvant arthritis AA model by intradermally injecting 0.1 mL Freund's complete adjuvant into the right paw. After 30 days, we observed the paw edema volume, arthritis index, pulmonary function, histomorphology, and Notch receptor/ligand of the lung tissue. RESULTS: Compared with the normal group, the paw edema volume, arthritis index, average expiratory flow within 0.3 s (FEV0.3/FVC), and the level of Notch3, Notch4 and Jagged2 of the lung tissue in the model group was significantly increased, while maximum expiratory flow at 50% of vital capacity (FEF50), maximum expiratory flow at 75% of vital capacity (FEF75), forced expiratory flow (PEF) and the expression of Notch1 of Jagged1 and Delta1 in the lung were significantly decreased (P<0.05, P<0.01). There were significant positive correlations between FEV0.3/FVC and Notch4. FEV0.3/FVC, FEF25, FEF50 and Notch3, Delta1 were negatively correlated, respectively (P<0.05, P<0.01). CONCLUSION While arthritis occurs in AA rats, pulmonary function declines and significantly correlates with the expression of Notch receptor/ligand. The deposition of immune complex in the lung after the injection of CFA activates the Notch signaling pathway, and results in further decline of pulmonary function by signaling cascades.

Diffuse pulmonary lymphangiomatosis (DPL) is a rare disease that is characterized by diffuse proliferation of abnormal pulmonary lymphatic channels. DPL occurs mostly in children and young adults and often undergoes a progressive clinical course, eventually causing deterioration of the lung. Both the clinical diagnosis and treatment of DPL remain a challenge. Here, we report a case of DPL in a 53-year-old Chinese woman with comprehensive investigations including pulmonary function tests, computer tomography (CT), bronchoscopy and histological examination of the lung biopsy, and review the literature.

This study was purposed to investigate the diagnostic value of fluorescence in situ hybridization (FISH) technique for the childhood acute myeloid leukemia (AML). The medical data of 179 children with AML (aged ≤ 16 years) were retrospectively studied, who were initially diagnosed in our hospital from April 2005 to April 2010. Through the analysis of the results of FISH, chromosome banding analysis and polymerase chain reaction, the difference and complementarity between FISH and other 2 methods for detecting the fusion genes were explored. The results indicated that the detection rate of genetic abnormality with FISH was higher. The PML/RARα probe was used in 27 AML-M3 patients, 22 out of whom were evaluated as PML/RARα positive. The AML1/ETO probe was used in 24 AML-M2b patients and all of them were evaluated as AML1/ETO positive. The CBFβ/MYH11 probe was used in 4 AML-M4Eo patients and all of them were evaluated as CBFβ/MYH11 positive. It is concluded that FISH is a sensitive method for detecting fusion genes and the results of FISH have a good correlation with the chromosome banding analysis and polymerase chain reaction. The combination of FISH with other 2 methods improves the detection rate of genetic abnormality, which is useful for the diagnosis and typing of childhood AML.

In addition to its well established role as a neurotransmitter, extracellular ATP has been considered as a paracrine/autocrine factor, either released from sperm or epithelial cells, in the male reproductive tract and shown to play a versatile role in modulating various reproductive functions. This review summarizes the signal pathways through which ATP induces anion secretion by the epithelia of the epididymis, as well as its epithelium-dependent modulation of smooth muscle contraction of the vas deferens. Finally, the overall role of ATP in coordinating various reproductive events in the male genital tract is discussed.

OBJECTIVETo investigate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in preoperative T-staging of gastric cancer.

METHODSA sulfur hexafluoride-filled microbubble ultrasound contrast agent and a continuous real-time imaging technique of contrast pulse sequencing were used. Normal gastric wall was examined by CEUS in 8 healthy volunteers and the results were compared with the findings on multislice computed tomography. Sixty-two patients with gastric cancer proved by biopsies who received preoperative CEUS examination were involved in this study, and the CEUS result was compared with postoperative pathological findings.

RESULTSThe normal gastric wall presented a one-layer structure in the portal venous phase and a three-layer structure in the arterial and equilibrium phase including a slightly hyper-enhanced inner layer, a hypo-enhanced intermediate layer, and a markedly hyper-enhanced outer layer, which corresponded histologically to the mucosal, submucosal, and muscular-serosal layer, respectively. The accuracy of transabdominal ultrasonography and CEUS in determining the T stage of gastric cancer was 72.9% and 88.1% respectively, and the difference was statistically significant (chi(2)=4.37, P=0.036).

CONCLUSIONSCEUS shows the normal gastric wall as a one- or a three-layer structure, which provides a theory base for CEUS in preoperative T-staging of gastric cancer. CEUS is a useful diagnostic method for preoperative T-staging of gastric cancer.
