Objective To investigate the clinical and imaging characteristics of isolated pontine infarction as well as the influencing factors for early progressive motor deficits (PMD) and short-term prognosis.Methods A total of 86 patients with isolated pontine infarction who admitted in hospital within 24 hours of symptom onset were analyzed retrospectively.The patients were divided into paramedian pontine infarction (PPI) and lacunar pontine infarction (LPI) according to the maximal diameter of the lesions and the locations of infarction.They were divided into either a PMD group or a non-PMD group according to the early status of PMD.They were also divided into a poor outcome group (mRS score ＞ 2) and a good outcome group (mRS score ≤ 2) according to the modified Rankin Scale (mRS) scores at discharge.The clinical and imaging features of the different patient groups were compared.Results The patients' constituent ratios of hyperlipidemia (57.14％ vs.33.33％;x2 =4.80,P=0.028),hemiplegia (97.14％ vs.72.55％;x2 =8.718,P=0.003),basilar artery stenosis (45.71％ vs.17.65％;x2=7.930,P=0.005) and poor outcome at discharge (54.29％ vs.31.37％ ; x2 =4.515,P =0.034),and the baseline National Institutes of Health Stroke Scale (NIHSS) scores (6.00 ± 2.39 vs.4.61 ± 3.41; t =2.087,P =0.040) in the PPI group (n =35) were significantly higher than those in the LPI group (n =51).The constituent ratios of the baseline diastolic blood pressure levels (97.82 ± 15.61 mm Hg vs.89.55 ± 12.23 mm Hg,1 mm Hg=0.133 kPa; t =2.258,P =0.031),PPI (63.64％ vs.32.81％ ;x2 =6.445,P =0.011) and basilar artery stenosis (59.10％ vs.18.75％ ;x2 =12.922,P =0.000) in the PMD group (n =22) were significantly higher than those in the non-PMD group (n =64).The baseline NIHSS scores (6.80 ± 2.63 vs.3.73 ± 2.55; t =5.426,P =0.000),fasting blood glucose levels (9.40 ±5.15 mmol/L vs.6.56 ±2.69 mmol/L; t =2.985,P=0.004) and the constituent ratios of PPI patients (54.29％ vs.31.37％ ;x2 =4.515,P =0.034) in the poor outcome group (n =35) were significantly higher than those in the good outcome group (n =51).Multivariate logistic regression analysis showed that basilar artery stenosis was an independent risk factor for the onset of PPI (odds ratio [OR] 3.801,95％ confidence interval [CI] 1.357-10.646; P =0.011) and the early PMD of isolated pontine infarction (OR 4.571,95％ CI 1.214-17.214; P=0.025).The baseline NIHSS score ≥ 5 was its independent predictor for poor outcome (OR 4.277,95％ OR 1.505-12.151; P =0.006).Conelusions PPI is mainly associated with the lesions in the branches of basilar artery.The baseline NIHSS score ≥ 5 may be an independent predictor for short-term poor outcome of isolated pontine infarction.Its early PMD and short-term poor outcome may be associated with the basilar artery lesions.

Objective To measure and analyze the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need (WISN)method,for reference of the government in building family doctor interdisciplinary teams.Methods 150 community health centers in 16 provinces were selected.The related data from 150 centers were collected to analyze the population served by each family doctor,and the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need(WISN)method.Results There were 10 721 community health professionals in the sample centers which provide 132.14 million standard equivalents of service to the public.1 9 6 1 6 community health professionals were needed to ensure the quality of service and no extra workload after work for professionals.Averagely,each family doctor can serve 1 558 residents,who needs 1.3~1.5 nurses or public health workers.Conclusions A huge gap was found for community health professionals.The population served by each family doctor should be lowered compared to the governmental requirement and more nurses should be introduced to the family doctor interdisciplinary team.

The most important harms of atrial fibrilation are stroke and the embolic events of the systemic circulation. The latest data have show n that the etiology of up to 1/3 of stroke patients w as atrial fibrilation. The stroke morbidity and mortality caused by atrial fibrilation are higher than other types of stroke. So the prevention of stroke is very important for patients with atrial fibrilation. The anticoagulant therapy is the core strategy for stroke prevention in patients with atrial fibrilation. This article reviews the advances in research on the safety and compliance of anticoagulation therapy in patients w ith atrial fibrilation.

Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.

Objective:To explore the association of miRNA-146a (miR-146a), miRNA-196a2 (miR-196a2), and miRNA-499 (miR-499) single nucleotide polymorphisms with genetic susceptibility in hepatocellular carcinoma.Methods:A case-control study was designed. A total of 175 patients (hepatocellular carcinoma group) in Affiliated Hospital of Yangzhou University from April 2015 to March 2019 and 302 healthy people undergoing physical examination during the same period (the control group) were selected. The genotype distribution of miR-146a, miR-196a2 and miR-499 in the peripheral blood of the two groups were detected by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Logistic regression model was used to analyze the association of 3 genotypes of miRNA, genotypes of hepatitis virus infectors with genetic susceptibility in hepatocellular carcinoma. The relationship between miR-146a gene polymorphism and demography factor as well as the clinical characteristics was also analyzed by using Spearman correlation analysis.Results:In hepatocellular carcinoma group, miR-146a single nucleotide polymorphism of CC, CG, GG site genotypes had 52 (29.7%) cases, 86 (49.1%) cases, 37 (21.1%) cases, respectively; in the control group, the corresponding genotypes had 137 (45.4%) cases, 135 (44.7%) cases and 30 (9.9%) cases, respectively, and the difference in genotype distribution of both groups was statistically significant ( χ2 = 17.23, P < 0.05). There were no statistical differences in genotype distribution of miR-196a2 and miR-499 ( χ2 = 0.51, P = 0.776; χ2 = 0.05, P = 0.976). Single factor logistic regression analysis showed that in the co-dominant model of miR-146a genotype, genotypes of CG ( OR = 1.96, 95% CI 1.13-3.41, P = 0.017) and GG ( OR = 3.30, 95% CI 1.85-5.89, P<0.01) had elevated risk of hepatocellular carcinoma compared with CC genotype. In the dominant model, the risk of hepatocellular carcinoma in CG+GG genotypes was increased compared with that in CC genotype ( OR=1.97, 95% CI 1.33-2.93, P = 0.001); in the recessive model, the risk of hepatocellular carcinoma in GG genotype was increased compared with that in CG+ GG genotype ( OR=2.43, 95% CI 1.44-4.11, P = 0.001). Single factor logistic regression analysis showed that there was no significant difference in the risk of hepatocellular carcinoma in the co-dominant, dominant and recessive models between miR-196a2 and miR-499 genotypes (all P > 0.05). For hepatocellular carcinoma patients with positive hepatitis B virus (HBV), CG genotype had a 2.02-fold (95% CI 1.06-5.07) risk of hepatocellular carcinoma compared with CC genotype, and GG genotype had a 3.12-fold (95% CI 1.66-10.07) risk of hepatocellular carcinoma compared with CC genotype; CG+GG genotype had a 1.91-fold (95% CI 1.85-3.38) compared with CC genotype, GG genotype had a 1.54-fold (95% CI 1.15-6.08) compared with CG+GG genotype. The increasing risk of hepatocellular carcinoma by miR-146a gene polymorphisms was not found in hepatocellular carcinoma patients with hepatitis C virus (HCV) infection or without HBV and HCV infection. Spearman correlation analysis showed that miR-146a gene polymorphisms was not related with age, gender, smoking, drinking, family history of cancer, alanine transaminase and aspartate aminotransferase (all P>0.05). Conclusions:GG and CG genotypes of miR-146a increase the risk of genetic susceptibility in hepatocellular carcinoma, especially for patients with HBV infection. miR-196a2 and miR-499 single nucleotide polymorphisms don't increase the risk of hepatocellular carcinoma.

Objective To observe therapeutic effects of intravesical instillation of mitomycin C (MMC) immediately after TUR added with low dose BCG maintenance therapy to prevent recurrence of superficial bladder cancer. Methods 83 patients with superficial bladder cancer were randomly divided into two groups, 50 cases were managed with intravesical instillation of mitomycin C immediately after TUR added with low dose BCG maintenance therapy (group A), 33 cases were treated with traditional method of MMC therapy (group B) to prevent recurrence of superficial bladder cancer. Results After 12-66 months (mean 32 months) following up, 3 patients had tumor recurrence in the group A and 7 patients in the group B, the rate of tumor recurrence of the group A was 6.0% (3/50) and that of the group B was 21.2%(7/33), and there was a significantly difference between two groups (P<0.05). Side effects of the group B were obviously more than that of the group A. Conclusion Intravesical instillation of MMC immediately after TUR added with low dose BCG maintenance therapy is effective to prevent patients with superficial bladder cancer from recurrence.

Objective To explore the impacts of natural ovulation cycles and stimulation cycles on the outcome of intrauterine insemination (IUI) in order to improve the clinical effects of IUI. Methods 176 women received 384 stimulation cycles. According to different ovulation stimulation protocols , the women were divided into six groups including natural cycle (NC) group, clomiphene citrate (CC) group, letrozole (LE) group;human menopausal gonadotrophin (HMG ) group, CC + HMG group, and LE + HMG group. The pregnancy rate between nature cycles and ovarian hyperstimulation cycles was compared. Results The pregnancy rate was 9.33%in the nature cycle group and 13.27% in the stimulation cycle group, with a significant difference (P < 0.05);and it dif not differ significantly among the stimulation cycle groups (P > 0.05). Conclusions Use of ovulation-induction medications is one of the important factors affecting the pregnancy rate of intrauterine insemination. There are no differences in the outcome of IUI among different ovulation stimulation protocols.

Objective To evaluate cardiac biomarkers as biological risk factors for cardiovascular and all-cause motality in HD patients.In addition,a multimarker approach including inflammatory index was performed to improve the cardiovascular and all-canse risk assessment of these patients.Methods The author measured Troponin-T (TnT),N-terminal pro brain natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (HsCRP),collected the clinical data at baseline (January 2012) in 229 HD patients in three hemodialysis centers in Haidian District of Beijing,recorded time and cause of death in the next 1000 days.Kaplan-Meier was used to calculate survival rate and impact factors of prognosis.Cox proportional hazard model was used to estimate significance of =TnT,NT-proBNP and HsCRP and adjusted hazard ratios (HRs) of death.Results During the followup,37 patients died,mainly from cardiac cause (54.05％,20/37).Univariate analysis found old age,diabetes,cardiovascular disease,low serum albumin,CRP≥3 mg/L,TnT≥0.1 mg/L,NT-proBNP≥ 4381 ng/L were associated with prognosis.Elevated cTnT,NT-proBNP or HsCRP were all associated with increased cardiovascular and all-cause motality.Moreover,the combination of all parameters (NTproBNP≥4381 ng/L and TnT≥0.1 mg/L and HsCRP≥3 mg/L) were dramatically associated with increased cardiovascular cause mortality (HR=25.25,P ＜ 0.01) and all-cause mortality (HR=27.33,P ＜ 0.01).The association were significant even after full adjustment for cardiovascular (HR=14.33,P ＜ 0.01) and all-cause mortality (HR=1 1.54,P ＜ 0.01) respectively.Conclusions A combined index of cardiovascular risk factors could provide supplementary risk stratification in HD patients for cardiovascular mortality and all-cause mortality,strongly supporting the annual routine determination of these biomarkers.

Objective To identify the specific genotype and analyze clinical features of spinocerebellar ataxias (SCAs) pedigree in the region of Yunnan Province.Methods Fourteen SCAs pedigrees and 183 blood samples of the family members were collected between January 2011 and July 2014 from Department of Neurology,First Affiliated Hospital of Kunming Medical College.Polymerase chain reaction (PCR) amplification,agarose gel electrophoresis and DNA sequencing technologies were utilized to identify the specific genotype of SCAs pedigree.Presymptomatic tests were carried out and the clinical features and genetic test results of patients were carefully analyzed.Results SCA3 was the most common subtype of SCAs in the Han nationality of Yunnan region.Nine of the 14 families were SCA3,only one family was SCA2.Additionally,there were four SCAs families that remained indeterminate.The patients with di-allele mutations (46/77) of SCA3 gene had early onset,rapid progression and serious clinical symptoms.Hereditary SCA3 and autonomic dominant polycystic kidney disease can happen simultaneously in a family.The proband SCA3 gene' s CAG repeat number is 28/76,and repetitions of the mutation allele are in all range.The PKD1 gene exon 23 is found to be in abnormal sequence.Conclusions SCA3 is the most common subtype of SCAs in the Han population of Yunnan region.There are 15/46 incomplete penetrance nutation and 46/77 di-allele mutations.It is possible that di-allele mutations make the disease worse and accelerate clinical course progression.SCA3 and polycystic kidney disease can uncommonly happen simultaneously in a family,which perhaps suggests there are interactions between the two disease-virulence genes.

Objective To investigate the impact of early enteral nutrition on the nutritional status and complications of patients with advanced esophageal carcinomas.Methods Sixty-five patients with advanced esophageal carcinomas were randomly divided into the enteral nutrition group group (n =33) and the control group (n =32).The two groups were given enteral nutrition support and normal nasogastric feeding diet respectively in 24-72 h after hospitalization.The two groups were tested with nutrition indicators:body Mass Index (BMI)/brachial triceps skinfold thickness/upper arm circumference measurement,fasting blood glucose/serum total protein/albumin/cholesterol/triglyceride and the liver function (alanine aminotransferase (ALT)/aspartate aminotransferase(AST)/total bilirubin (TBiL)),and were observed the incidences of complications with liver/intestinal and infection diseases.Results After one month's treatment,compared with the control group,there was significant statistical difference between the two group in patients' nutritional status (BMI index:(22.1 ±4.5) kg/m2 vs.(19.2±4.3) kg/m2; skinfold thickness:(6.2 ±0.4) mm vs.(5.1 ±0.4)mm ; upper arm circumference:(22.8 ± 3.0) cm vs.(20.4 ± 3.2) cm ; serum total protein:(49.2 ± 10.1) g/L vs.(45.1 ± 9.9) g/L; Albumin:(35.5 ± 5.8) g/L vs.(30.6 ± 6.1) g/L; Cholesterol:(5.0 ± 0.6) mmol/L)vs.(4.3 ± 0.7) mmol/L)),the liver function(ALT:(36.0 ± 4.7) U/L vs.(61.5 ± 9.9) U/L; AST:(29.6 ±6.7) U/Lvs.(88.9±10.6) U/L;TBiL:(17.7±3.8) μmol/Lvs.(31.6 ±9.4) μmol/L) (t=2.624,2.036,2.220,2.256,4.155,2.207,2.349,2.476,2.280 respectively,P ＜ 0.05 for all),and the incidence of diarrhea (12％ (4/33) vs.34％ (11/32)) and infection (15％ (5/33) vs.41％ (13/32)) (x2 =2.501,2.193 respectively;P ＜0.05).No statistical difference was observed between the two groups on the levels of serum glucose and triglycerides,and the incidences of complications like bloating/constipation/reflux (P ＞ 0.05).Conclusion The early enteral nutrition could improve the nutritional status of patients with advanced esophageal carcinomas effectively,and reduce the incidence of liver injury,diarrhea and infection.
