OBJECTIVETo analyze the association between hypertension and tobacco exposure Luoping county of Yunnan province and estimate the direct cost attributable to hypertension .

METHODSUsing Probability proportional to size (PPS) sampling method, 5000 rural residents aged over 18 years were selected from 12 townships in Luoping county, Yunnan province in April 2011, from which 4611 subjects completed the survey. Self-designed questionnaires were used to collect general information, smoking status, costs for outpatient consultation, inpatient, treatment, medication, travel, accommodation and extra-nutrition caused by hypertension as well as the information of health-related behavior. Their height, weight, waist circumference, hip circumference and blood pressure were measured. The direct economic burden of hypertension was calculated. Chi-square (χ(2)) test was used to compare gender differences of hypertension prevalence, smoking and passive smoking. And t test was used to compare the differences of direct economic burden of hypertension among different gender, smoking and passive smoking status. Multivariable logistic regression model was used to analyze the influence factors of hypertension.

RESULTSAmong the 4611 subjects, the age was (46.90 ± 16.74) years old. Male accounted for 49.8% (2294/4611) and female 50.2% (2317/4611) . The smoking rate was higher in males (75.7% (1736/2294)) than in females(1.6% (38/2317)) (χ(2) = 2669.21, P < 0.01). The passive smoking rate was lower in males (10.0% (230/2294)) than in females (46.2% (1070/2317)) (χ(2) = 744.27, P < 0.05). Non-tobacco exposure rate in males (14.3% (328/1537)) was lower than in females (52.2% (1209/1537)) (χ(2) = 744.37, P < 0.05) . The risk of hypertension in smokers and passive smokers were higher than those without tobacco exposure, OR (95%CI) was 1.41 (1.15-1.71) (P < 0.05) and 1.31 (1.07-1.63) (P < 0.05) respectively. The per capita direct cost of hypertension was (3444.09 ± 3067.83) Yuan. Of this, tobacco exposure (4552.46 ± 3189.05) Yuan was higher than non-tobacco exposure (1907.71 ± 1383.94) Yuan (t = -3.81, P < 0.05) . Moreover, smokers were (6951.71 ± 3422.87) Yuan higher than passive smokers (3128.09 ± 2083.17) Yuan (t = 3.19, P < 0.05) and males (5827.39 ± 3240.50) Yuan were higher than females (2633.03 ± 2569.01) Yuan (t = 3.22, P < 0.05) . The total direct costs of hypertension attributable to smoking and SHS was 41 million and 38 million, respectively.

CONCLUSIONBoth smoking and SHS had significant impact on prevalence and economic burden of hypertension in Luoping county. Implementing effective strategies to control tobacco exposure is useful to reduce the economic burden of hypertension in the study region.

OBJECTIVETo explore the intervention timing of acupuncture in treatment of cerebral infarction and the relationship of cerebral ischemia reperfusion injury with inflammatory cytokine receptor.

METHODSOne hundred and ten male healthy Wistar rats were randomly divided into a normal group (n=10), a sham operation group (n=10), a model group (n=10), an acupuncture at non-acupoint group (non-acupoint group, n=40), an acupuncture with regaining consciousness method group (regaining consciousness group, n=40). Four subgroups were set up 1 h ischemia reperfusion in 1 h group, 3 h group, 6 h group, 12 h group in the two acupuncture groups, 10 rats in each subgroup. Two acupuncture groups were treated with acupuncture at four time points (1 h, 3 h, 6 h and 12 h after ischemia reperfusion), and "Shuigou" (GV 26) and "Neiguan" (PC 6) were selected in regaining consciousness group, and the non-acupoints below the bilateral costal region were selected in non-acupoint group. At the corresponding time point, the tissues of the brain were removed and interleukin1 receptor (IL-1RI) and tumor necrosis factor receptor (TNFR-I) mRNA and protein changes were detected by using real-time quantitative polymerase chain reaction and immunoblot assay.

RESULTSThe expression of IL-1RI and TNFR-I mRNA and protein in the model group were significantly higher than that in normal group, sham operation group, regaining consciousness group and non-acupoint group (P<0.01, P<0.05). The expression of IL-1RI and TNFR-I mRNA and protein in regaining consciousness group was weakest at 3 h after reperfusion followed successively by 6 h, 1 h, 12 h, and there was no significantly change of IL-1RI and TNFR-I mRNA and protein expression in non-acupoint group among different timing points, but which was decreased as compared with those in the model group at the same time point (all P<0.05).

CONCLUSIONAcupuncture can reduce the expression of IL-1RI and TNFR-I mRNA and protein in rats with cerebral ischemia reperfusion, inhibit the excessive expression of proinflammatory cytokine receptor, block apoptosis signal transduction and extend time window for treatment of cerebral ischemia, so as to play the protective effect for brain. Within 3 h of ischemia is the best time for intervention of acupuncture treatment.

OBJECTIVETo observe the effect of Yangxueqingnao particles on rat vascular smooth muscle cell (VSMC) proliferation induced by lysophosphatidic acid (LPA).

METHODSThe amount of (3)H-TdR ((3)H-thymidine) admixed in cultured rat VSMC was measured and mitogen-activated protein kinase (MAPK) activity and lipid peroxidation end product malondialdehyde (MDA) content of the VSMC were assayed.

RESULTS1x10(-9), 1x10(-8), 1x10(-7) mol/L LPA in a concentration dependent manner, induced the amount of (3)H-TdR admixed, MAP kinase activity, and MDA content of the cultured rat VSMC to increase. However, 5%, 10%, and 15% Yangxueqingnao serum preincubation resulted in a decrease of 23.0%, 42.0%, and 52.0% (P<0.01) respectively in the amount of (3)H-TdR admixed, a decline in VSMC MAP kinase activity of 13.9% (P<0.05), 29.6% (P<0.01), and 48.9% (P<0.01) respectively, and also, a decrease in MDA content of VSMC of 19.4%, 24.7%, and 43.2% (P<0.01) respectively, in the 1x10(-7) mol/L LPA-treated VSMC.

CONCLUSIONSLPA activates the proliferation and lipid peroxidation of VSMC in a concentration dependent manner. The LPA-induced VSMC proliferation is related to the activity of MAP kinases, enzymes involved in an intracellular signalling pathway. The results of the present study showed that Yangxueqingnao particles can effectively inhibit LPA-induced VSMC proliferation, MAP kinase activation, and reduce lipid peroxidative lesion.

Objective To explore the associations between cesarean section with different types and intensity of physical activity in the second trimester pregnant women． Methods Six hundred and seventy－two participants from the Chinese pregnant women cohort study ( CPWCS) were analyzed． The pregnancy physical activity questionnaire ( PPAQ) was used to collect the status of physical activities in pregnant women． The participants were followed up and the data of delivery way was collected． Logistic regression model was conducted to analyze the associations． Ｒesults A total of 273 pregnant women ( 40. 63%) were delivered by cesarean section． After adjusting age，pre-pregnancy BMI and history of childbirth，results of Logistic regression model showed that pregnant women with higher levels of exercise had a lower risk of cesarean section than those who did not participate in exercise ( OＲ= 0. 564，95% CI: 0. 338－0. 941) . In terms of physical activity intensity，pregnant women who participated in the higher level of moderate to vigorous physical activity had a lower risk of cesarean section than those who partici- pated in the lower level ( OＲ= 0．642，95% CI: 0．437－0．972) ． Conclusions Exercise and moderate to vigorous physical activity are protective factors for cesarean section． Health education should be further strengthened to encourage pregnant women to carry out appropriate physical activity during pregnancy．

Objective To explore the association between unhealthy diets and depression in early pregnancy. Methods 7 976 women in early pregnancy were recruited and analyzed in this study from the Chinese Pregnant Women Cohort Study (CPWCS) from July 25th, 2017 to July 24th, 2018. Differences of baseline characteristics between the two groups were conducted by a chi-square test. The qualitative food frequency questionnaire and the edinburgh postnatal depression scale were used to assess depression status and food intake frequency during the first trimester respectively. Log-binomial regression was used to analyze the relationship between unhealthy diets and depression in early pregnancy. Prevalence ratio (PR) and its 95% confidence interval (95% CI) were calculated. Results Eating regularly (PR=0.45, 95% CI:0.38-0.54，P<0.001) and eating breakfast frequently (PR=0.80, 95% CI:0.72-0.90, P<0.001) were related to the low incidence of depression while frequent consumption of fried food (PR=1.25, 95% CI:1.03-1.53, P=0.027), Western-style fast food (PR=1.36, 95% CI:1.06-1.74, P=0.015) and puffed food (PR=1.37, 95% CI:1.11-1.70, P=0.003) as well as drinking sugar-sweetened beverage (PR=1.37, 95% CI:1.17-1.61, P<0.001),wine (PR=1.60, 95% CI:1.26-2.01, P<0.001) and liqueur (PR=1.26, 95% CI:1.00-1.59, P=0.047) were linked with the high incidence of depression. Conclusions There might be an association between unhealthy diets and depression in early pregnancy. Pregnant women should take the initiative to better understand what are healthy diets and reduce the frequency of unhealthy diets consumption to decrease the incidence of depression during pregnancy.

OBJECTIVETo confirm the existence of Amur-like viruses in Apodemus peninsulae in China, and to understand the molecular characteristics of these viruses.

METHODSTotal RNA was extracted from lungs of A. peninsulae captured in Jilin of Northeast China with Trizol reagent. Complete S and partial M segments of Amur virus were amplified and sequenced. Phylogenetic analyses on multiple nucleotide sequences were performed with the Clustal method and DNASTAR software.

RESULTS383 bp cDNA of M segment and 1696 bp of S segment of Amur like virus were recovered from lung tissue of A. peninsulae, named JilinAP06. The full-length of its S gene comprised of 1696 nucleotides with ORF including 1287 nucleotides and encoding a protein which comprised 429 amino acids. The phylogenetic analysis of this sample with other hantaviruses revealed that the complete S and partial M segment sequence of JilinAP06 both were closely related to those Amur viruses such as AP63, AP61, AP1371 and AP1168 found in A. peninsulae from Far East region of Russia and B78 strain, Liu strain and H5 strain, which were all from Chinese patients. The complete S and partial M segment sequence of JilinAP06 had only 81.0% identities with the nucleotide sequences of HV prototype 76-118 strain.

CONCLUSIONAmur-like viruses did exist in A. peninsulae from Northeasern China while A. peninsulae might be the natural reservoir of Amur-like viruses in China and was the important infectious source to HFRS patients which were caused by Amur-like viruses.

Objective To explore the influence of reproduction history on depression during pregnancy． Methods Data on 3 792 pregnant women from the Chinese pregnant women cohort study with complete information on reproduction history and depression were used in the present study． The Edinburgh postnatal depression scale was used to assess depression status among pregnant women． A chi-square test was used for univariate analysis，and a Log－binomial regression was used for multivariate analysis． The adjusted relative risks ( ＲＲs) with 95% confidence intervals ( 95% CIs) were calculated，and were presented in a forest plot． Ｒesults The results of Log－binomial regression showed that a history of delivery could increase the risk of depression during the second trimester ( ＲＲ: 1. 04，95% CI: 1. 01 － 1. 08，P= 0. 042) and the third trimester ( ＲＲ: 1. 05，95% CI: 1. 01－1. 10，P= 0. 020) ． There was a 6% increase of risk on depression in women with a history of cesarean delivery compared with women without that during the third trimester ( ＲＲ: 1. 06，95% CI: 1. 01－1. 11，P = 0. 041) ． Conclusions There is asignificant influence of reproduction history on gestational depression． Maternal and child health personnel should focus on these pregnant women，and conduct targeted health education and mental nursing． In addition，medical personnel should also pay attention to the emotional changes of these women and provide them with several adjustment strategies．

Cervical spondylotic radiculopathy(CSR)is a condition caused by the degeneration of cervical intervertebral discs and facet joints,primarily manifesting as the pain,sensory abnormalities,and motor dysfunction in the cervical nerve innervation area of neck,shoulder,and upper limb.For the treatment of CSR,tendon-bone syndrome differentiation in traditional Chinese medicine often faces the issues of conceptual confusion and non-standard syndrome differentiation.Based on the traditional tendon-bone syndrome differentiation and by integrating modern anatomical insights,Professor LIN Ding-Kun,an esteemed scholar of Traditional Chinese Medicine,proposed a classification system for the cervical spine that includes the categories of tendons,joints,bones and marrow.This paper explored the thoughts of Professor LIN for the tendon-bone syndrome differentiation of CSR,summarized the targets of manual therapy,and proposed the four kinds of pathological changes such as tendon overstrain,joint dislocation,bone lesion,and marrow injury,as well as the four techniques of traditional Chinese medicine manipulations,i.e.relaxation of tendons,reduction of joints,protection of marrow,and treatment of bones.The aim is to improve the syndrome-differentiation and treatment for CSR with orthopedic and traumatologic manipulations,and to provide reference for clinical practice.

Background:Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD).The study is to evaluate the efficacy and safety of tACS treating MDD.Methods:This is an 8-week,double-blind,randomized,placebo-controlled study.Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min,77.5-Hz,15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4),following a 4-week observation period (week 8).The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8.Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17,the proportion of participants having improvement in the clinical global impression-improvement,the change in HDRS-17 score (range,0-52,with higher scores indicating more depression) over the study,and variations of brain imaging and neurocognition from baseline to week 4.Safety will be assessed by vital signs at weeks 4 and 8,and adverse events will be collected during the entire study.Discussion:The tACS applied in this trial may have treatment effects on MDD with minimal side effects.
