OBJECTIVETo investigate the coping strategies of the community-based population in Shenzhen.

METHODSTotally 5,940 subjects from the communities in Shenzhen were sampled and tested with the Simplified Coping Style questionnaire.

RESULTSThe most common coping strategies adopted by the community residents in Shenzhen were "consoling themselves" (33.1%) and "looking at the bright side of things" (31.4%), and the least adopted coping strategy was "relieving distress by smoking, drinking, taking medicine and eating" (57.8%); the strategies left out from their choices were mostly negative strategies. The scores for positive coping strategy factors of community residents in Shenzhen were greater than those of negative ones, with a mean difference of 0.43. The scores of both positive and negative coping strategy factors of these residents were significantly lower than those of general population in other mainland cities (P<0.001), with mean differences of 0.12 and 0.36, respectively.

CONCLUSIONThe community residents in Shenzhen adopt mostly positive strategies for coping with frustration, which benefit their status of self-rated health.

OBJECTIVETo observe characteristics of acupuncture in improvement of sleep quality in the patient of insomnia.

METHODSForty-six cases of primary insomnia were randomly divided into an observation group (n = 24) and a control group (n = 22). The observation group were treated by the needling method for regulating mental activity, with Baihui (GV 20), Shenting (GV 24), Shenmen (HT 7) selected as main points; the control group were treated with oral administration of Estazolam. The therapeutic effects and scores of Pittsburgh Sleep Quality Index Scale before and after treatment were compared between the two groups.

RESULTSThe total effective rate was 83.3% in the observation group and 72.7% in the control group, the observation group being better than the control group (P < 0.05). Estazolam was better than acupuncture treatment in prolonging sleeping time, and the acupuncture treatment was better than the control group in the improvement of somnipathy and the increase of daytime functional state (P < 0.05).

CONCLUSIONAcupuncture treatment has advantages of improving somnipathy and increasing daytime functional state.

OBJECTIVETo reconfirm the association of KPNB3 with schizophrenia in Chinese population.

METHODSTwo single nucleotide polymorphisms (SNPs), rs2588014 and rs626716 at the KPNB3 locus, were genotyped in 304 Chinese Han family trios consisting of fathers, mothers, and affected offsprings with schizophrenia. These 2 SNPs were detected by PCR-based restriction fragment length polymorphism (RFLP) analysis. The Hardy-Weinberg equilibrium for genotypic distributions was estimated by the goodness-of-fit test. The UNPHASED program was used to perform transmission disequilibrium test (TDT), haplotype analysis, and pair-wise measure of linkage disequilibrium (LD) between these 2 SNPs.

RESULTSThe genotypic distributions of both rs2588014 and rs626716 were in the Hardy-Weinberg equilibrium (P > 0.05). The TDT revealed allelic association with rs626716 (chi2 = 9.31, P = 0.0023) but not with rs2588014 (chi2 = 3.44, P = 0.064). The global P-value was 0.0099 for 100 permutations. The haplotype analysis also showed a disease association (chi2 = 25.97, df = 3, P = 0.0000097).

CONCLUSIONThe present study provides further evidence in support of the KPNB3 association with schizophrenia in Chinese population.

OBJECTIVETo compare the effects of instant electroacupuncture (EA) at the different acupoints on IP3 in the uterus tissue of dysmenorrhea model rats so as to investigate the specificity of acupoints.

METHODSFifty female SD rats were randomly divided into a saline group, a model group, a Sanyinjiao (SF 6) group, a Xuehai (SP 10) group and a Hegu (LI 4) group, 10 rats in each group. The rats were given subcutaneous injection of Estradiol Beozoate injection for 10 consecutive days except those in the saline group, and intraperitoneal injection of 2U Oxytocin at 1 h after the last administration to create the dysmenorrhea rats model, and the saline group was given the same dose of saline every day. On the 10th day the rats in each EA group were given EA 20 min, and the rats in the saline group and model group were bound 20 min, and the writhing response was observed at the same time. The uterine IP3 contents were detected with enzyme-linked immunosorbent assay method.

RESULTS(1) Compared with (0.311+/- 0.253) in the saline group, the writhing scores per minute of (5.867 +/- 3.442) in the model group and (2.311 +/- 0.957) in the Xuehai (SP 10) group were both increased significantly (P < 0.01, P < 0.05), and (1.833 +/- 1.355) in the Sanyinjiao (SP 6) group and (0.743 +/- 0.306) in the Hegu (LI 4) group showed no significant differences (P > 0.05). Compared with that in the model group, the writhing scores per minute decreased significantly (all P < 0.01) in all the EA groups, with no significant differences among all the EA groups (all P > 0.05). (2) Compared with (2.698 +/- 1.491) ng/mg in the saline group, IP3 contents of the uterus of (0.813 +/- 0.899) ng/mg in the model group, (1.740 +/- 0.375) ng/mg in the Sanyinjiao (SP 6) group and (0.692 +/- 0.212) ng/mg in the Hegu (LI 4) group were all lower significantly (P < 0.05, P < 0.01), and (0.743+/- 0.306) ng/mg in the Xuehai (SP 10) group showed no significant differences (P > 0.05). Compared with that in the model group, IP3 content of the uterus in the Hegu (LI 4) group showed no significant difference (P > 0.05), and those in the Sanyinjiao (SP 6) group and in the Xuehai (SP 10) group increased significantly (both P < 0 05), which were significantly higher than that in the Hegu (II 4) group (P < 0.05, P < 0.01).

CONCLUSIONThere are no significant differences among the instant EA groups in improving the dysmenorrhea symptoms, but there is obvious specificity of acupoint effects in the regulation of IP3. Electroacupuncture at "Sanyinjiao (SP 6) " Xuehai (SP 10)" has more marked effect in dysmenorrhea model rats.

OBJECTIVETo explore the effects of pre-acupuncture and immediate acupuncture on kidney function and oxygen free radical metabolism in rats with simulated weightlessness.

METHODSTwenty male clean-grade Wister rats were randomly divided into a normal control group, a model group, a pre-acupuncture group and an immediate acupuncture group, 5 rats in each one. The rats in the normal control group did not receive any treatment but free activities for 4 weeks. The rats in the rest groups received 4-week tail suspension to establish the model of simulated weightlessness. One week before the tail suspension, the rats in the pre-acupuncture group were treated with electroacupuncture at "Shenshu" (BL 23), "Pishu" (BL 20) and "Sanyinjiao" (SP 6) for 30 min per treatment, once a day for 7 days. The rats in the immediate acupuncture group received tail suspension and acupuncture at the same time; during the tail suspension, the electroacupuncture was applied at "Shenshu" (BL 23), "Pishu" (BL 20) and "Sanyinjiao" (SP 6) for 30 min per treatment, once every other day for 14 days. The colorimetric method was used to measure the content of blood urea nitrogen (BUN) in serum as well as activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) and content of malonaldehyde (MDA) in renal tissue in each group.

RESULTSCompared with the normal control group, the content of BUN in the model group was increased significantly (P<0.01), the activity of SOD and GSH-PX in nephridial tissue was significantly reduced (both P<0.01), and the content of MDA was increased significantly (P<0.05). Compared with the model group, the content of BUN in the pre-acupuncture group and immediate acupuncture group was significantly reduced (P<0.01, P<0.05), the activity of GSH-PX in the pre-acupuncture group was obviously increased (P<0.05) and the content of MDA in the immediate acupuncture group was increased significantly (P<0.01). Compared with the immediate acupuncture group, the content of MDA in the pre-acupuncture group was lower (P<0.01).

CONCLUSIONThe pre-acupuncture and immediate acupuncture both have the capacity to improve the kidney function and anti-oxygen free radical injury in rats with simulated weightlessness, however, the capacity to increase the protection ability of the kidney and eliminate free radical in the pre-acupuncture group is superior to that in the immediate acupuncture group, which is likely to be related with improving antioxidant ability of kidney.

Objective To analyze the epidemiological characteristics of COVID-19 cases reported in Xianyang City from January to February 2020. Methods We retrospectively studied 17 COVID-19 patients diagnosed in Xianyang Central Hospital. The patients were characterized clinically and epidemiologically. Results The 17 patients included 10 male and 7 female, with an average age of(39.59±17.31)years. The median interval of time between onset and diagnosis was four days(1-10 days), whereas the median duration of COVID-19 was 16 days(3-23 days). Of the patients, six were mild, 10 were pneumonia, and one was severe. A total of 15 patients had fever as the onset, accompanied by fatigue, sore throat, sputum, vomit, muscle soreness; the other two patients were asymptomatic. There were no complications documented in all the patients. Patients had low levels of white blood cells and lymphocytes. Chest CT scan showed diverse diffuse ground-glass shadow. Eleven patients had travel history in Wuhan before the onset, four patients had contact with people who had travel history or residence history in Wuhan, and the other two patients did not report epidemiological exposure history. In addition, four of the 17 patients were clustered cases. Conclusion General population is susceptible to COVID-19. The majority of the confirmed cases have epidemiological exposure history. Routine examination, including white blood cell, lymphocyte count and CT scan may facilitate early diagnosis.

OBJECTIVE To explore the effect and mechanism of Bushen Zhuyun formula(BSZYF)on gonadotropins and gonadotropin-releasing hormone receptor(GnRHR)signaling transduction in mifepristone-induced LPD rats,and to find the scientific evidence of"heart,kidney and uterus axis"theory of TCM.METHODS SD female rats were administered mifepris-tone suspension via oral gavage,followed by pharmaceutical intervention.Then,the serum follicle-stimulating hormone (FSH)and luteinizing hormone(LH)levels were detected by ELISA assay,the FSHβand LHβexpression levels in the pitui-tary were determined by qPCR,and the GnRHR expression levels were assessed by qPCR and Western blot analysis.Simulta-neously,transcription factors,such as c-Jun,Elk-1,Egr-1,Nur77 and CREB,and transduction molecules in PKC-MAPK, Ca2+-CAM,and cAMP-PKA signaling pathways,such as PKC,p38MAPK,ERK1/2,CAM,and PKA were assessed by qPCR and Western blot analysis.RESULTS After pharmaceutical intervention,BSZYF increased the serum FSH levels sup-pressed by mifepristone(P<0.05).Moreover,the expression of c-Jun,Elk-1,Egr-1,CREB,PKA,p38MAPK,JNK,ERK and PKA were was significantly upregulated in the BSZYF group compared with that in the mifepristone group(P<0.05). However,there was no statistical difference in Nur77 and CAM expression among the blank,mifepristone and BSZYF groups (P>0.05).CONCLUSION BSZYF can regulate abnormal pituitary gonadotropin secretion and GnRHR signaling transduc-tion systems induced by mifepristone,which confirms that the prescription can regulate the whole function of the reproductive axis,and explains the consistency of"Heart,kidney and uterus axis"theory in TCM and the concept of the hypothalamus-pitu-itary-ovary axis in modern medicine

BACKGROUND/AIMS: Methylation status plays a causal role in carcinogenesis in targeted tissues. However, the relationship between the DNA methylation status of multiple genes in blood leukocytes and colorectal cancer (CRC) susceptibility as well as interactions between dietary factors and CRC risks are unclear. METHODS: We performed a case-control study with 466 CRC patients and 507 cancer-free controls to investigate the association among the methylation status of individual genes, multiple CpG site methylation (MCSM), multiple CpG site heterogeneous methylation and CRC susceptibility. Peripheral blood DNA methylation levels were detected by performing methylation-sensitive high-resolution melting. RESULTS: Total heterogeneous methylation of CA10 and WT1 conferred a significantly higher risk of CRC (adjusted odds ratio [OR(adjusted)], 5.445; 95% confidence interval [CI], 3.075 to 9.643; OR(adjusted), 1.831; 95% CI, 1.100 to 3.047; respectively). Subjects with high-level MCSM (MCSM-H) status demonstrated a higher risk of CRC (OR(adjusted), 4.318; 95% CI, 1.529 to 12.197). Additionally, interactions between the high-level intake of fruit and CRH, WT1, and MCSM on CRC were statistically significant. CONCLUSIONS: The gene methylation status of blood leukocytes may be associated with CRC risk. MCSM-H of blood leukocytes was associated with CRC, especially in younger people. Some dietary factors may affect hypermethylation status and influence susceptibility to CRC.
