Objective There is little population-based data on the prevalence and the environmental or genetic determinants of left ventricular hypertrophy (LVH) in China. The purpose of this paper is to study LVH in relation to systolic blood pressure and the angiotensin converting enzyme (ACE) insertion/deletion(I/D) polymorphism in Chinese. Methods We recorded 12-lead ECG (CardioSoft, v4.2) in 1365 residents in the Jingning County, Zhejiang Province, China. LVH was defined according to the gender-specific Sokolow-Lyon and Comell product ECG criteria. Results Regardless of whether the Sokolow-Lyon or Comell product ECG criteria was used, the prevalence of LVH (20.7% and 4.8%, respectively) significantly (P<0.0001) increased with male gender (odds ratio [OR] 2.33 and 7.15) and systolic blood pressure (per 10 mm Hg increase, OR 1.46 and 1.33). If the Sokolow-Lyon criteria was used, the prevalence of LVH was also influenced by alcohol intake (OR 1.44, P=0.03) and body mass index (OR 0.83, P=0.0005). The association between the Sokolow-Lyon voltage amplitude and the ACE I/D polymorphism was dependent on antihypertensive therapy (P=0.01). In 1262 untreated subjects, but not 103 patients on antihypertensive medication, the ACE DD compared with Ⅱ subjects had significantly higher Sokolow-Lyon voltage amplitudes (29.8±0.6 vs. 28.0±20.5 mV, P=0.02) and higher risk of LVH (OR 1.74, 95% CI: 1. 12-2.69, P=0.01). Conclusion LVH is prevalent in Chinese, and is associated with systolic blood pressure and the ACE D allele. The genetic association might be modulated by antihypertensive therapy.

Objective To understand the correlations between HIV-1 subtypes and changes in CD4+T cell count over time in patients with different subtypes of HIV-1 infection.Methods A total of 94 patients who were diagnosed with HIV-1 infection in Nanjing and received at least twice CD4+T cell counting test before antiretroviral therapy (ART) were recruited in this study.Descriptive analysis was used to present the rates of CD4+T cell decline for different HIV-1 subtypes.Logistic regression analysis and nonparametric test were conducted to investigate the factors responsible for CD4+T cell decline and to analyze the correlations between the rates of CD4+T cell decline and HIV-1 subtypes.Results The median monthly rate of CD4+T cell decline was-2.20 [interquartile range (IQR):-11.36-2.13] cell/μl.Of all patients,25.5% (24/94) had a significant decline (≥30%) in CD4+T cell count.Compared with the patients infected with CRF01_AE,those infected with CRF07_BC (OR=0.28,95%CI: 1.7-6.5) or other subtypes (OR=0.16,95%CI: 1.0-2.9) had a lower risk of significant decline in CD4+T cell count.In addition,results of the nonparametric test showed that the patients infected with CRF01_AE (M=-21.54,IQR:-30.97——11.92 cell/μl) had a faster CD4+T cell loss than those infected with CRF07_BC (M=-11.26,IQR:-14.06——5.63 cell/μl) (P=0.033).Conclusion HIV-1 subtype is associated with the rate of CD4+T cell decline.It is important to monitor the changes in CD4+T cell count in patients infected with CRF01_AE and to carry out timely ART.

Objective To evaluate the relationship between plasma cystatin C concentration (PcyC) and coronary artery diseases (CAD). Method A total of 126 subjects with CAD evidenced by coronary angiography admitted from April 2007 to March 2009 were divided into three groups: stable angina pectoris (SAPs, n = 34),unstable angina pectoris (UAPs, n = 56) and acute myocardial infarction (AMIs, n = 36), according to the diag-nostic criteria of CAD set by WHO. Another 34 subjects without CAD were taken as controls. There were no statis-tical differences in demographics among four groups. Serum lipids profile, uric acid (UA), PcyC and high-sensi-tive C-reactive protein (hs-CRP) were determined. And in the meantime, all patients were followed up for six months and adverse cardiovascular events were recorded. Comparisons were made between groups with a number of independent-sample t -tests. Data were processed with analysis of variance to test the differences in means among four groups, and the means were compared with chi-square test. Statistical significance was established at a P val-ue of less than 0.05. Results Cystatin C levels were significantly higher in UAPs than that in SAPs and in controls (P < 0.05), but were much lower than that in AMIs (P < 0.05). And much higher concentration of hs-CRP was found in UAPs (P < 0.05) and in AMIs (P < 0.01). Cystatin C was positively and significantly corre-lated with age, hs-CRP, WBC, creatinine and UA (r > 0, P < 0.05), whereas a significantly negative correla-tion with high-density lipoprotein cholesterol was found (r = - 0.227, P < 0.05). These coefficients were obvi-ously high for creatinine (r = + 0. 612), and WBC (r = + 0.459). During the period of six-month follow-up, 26 patients with adverse cardiovascular events were found, and had significantly higher cystatin C levels than 22 con-trols at admission (P < 0.01). Conclusions Cystatin C plays a pivotal role in the course of CAD, and the PcyC is a strong predictor for the risk of cardiovascular events.

This study examined the prevalence of primary open-angle glaucoma (POAG) among residents aged &ge;50 years living in Yongchuan district of Chongqing. Stratified cluster sampling was employed in random selection to estimate the prevalence of glaucoma from April to June, 2005. Twenty-nine villages or neighborhood communities were randomly selected in urban area (Zhongshan Road), suburban area (Shanjiao Town) and exurban area (Zhutuo Town) of this district. All the respondents underwent detailed ophthalmic examinations. The examinations included questionnaire investigation, visual acuity test, naked-eye examination, measurement of peripheral anterior chamber depth (Van Herrick's technique), detection of intraocluar pressure (IOP) with a Perkins hand-held applanation tonometer (HA-2) and examination of the optic disc by using a 78 diopters (D) lens (including the cup-disc ratio, cup/disc ratio asymmetries, horizontal and vertical diameter, notching and optic disc hemorrhages). A total of 5938 residents were actually examined, and the response rate was 85.19%. The crude prevalence of POAG was 0.86% (n=51/5938, 95% CI 0.64%-1.11%). There were 24 males and 27 females in the glaucoma group. The glaucoma prevalence was not significant different in case number between the male and female subjects (P=0.4900). Furthermore, no association between age or schooling and POAG was noted (P=0.8030, 0.0734). Out of 51 subjects with POAG, unilateral glaucoma-related blindness occurred in 38 subjects (74.5%) and bilateral glaucoma-related blindness was found in 7 subjects (13.7%). This study exhibited that the prevalence of POAG was 0.86% among residents aged &ge;50 years living in Yongchuan District of Chongqing. The vision loss caused by POAG in this population was obviously higher than that previously reported in other studies. Glaucoma management, detection of affected persons and handling of the burden of glaucoma should be the priorities of the agenda of local health authorities of Western China.

OBJECTIVE: To study the significance of the level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and bronchoalveolar lavage fluid (BALF), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score in evaluating the conditions and prognosis of children with severe pneumonia. METHODS: A total of 76 children with severe pneumonia who were admitted from August 2017 to October 2019 were enrolled as the severe pneumonia group. According to the treatment outcome, they were divided into a non-response group with 34 children and a response group with 42 children. Ninety-four children with common pneumonia who were admitted during the same period of time were enrolled as the common pneumonia group. One hundred healthy children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum level of sTREM-1, APACHE II score, and SOFA score were measured for each group, and the level of sTREM-1 in BALF was measured for children with severe pneumonia. The correlation of the above indices with the severity and prognosis of severe pneumonia in children was analyzed. RESULTS: The severe pneumonia group had significantly higher serum sTREM-1 level, APACHEII score, and SOFA score than the common pneumonia group and the control group (P<0.05). For the children with severe pneumonia, the non-response group had significant increases in the levels of sTREM-1 in serum and BALF and SOFA score on day 7 after admission, while the response group had significant reductions in these indices, and there were significant differences between the two groups (P<0.05). Positive correlation was found between any two of serum sTREM-1, BALF sTREM-1, and SOFA score (P<0.05). APACHE II score was not correlated with serum sTREM-1, BALF sTREM-1, and SOFA score (P>0.05). CONCLUSIONS The level of sTREM-1 in serum and BALF and SOFA score can be used to evaluate the severity and prognosis of severe pneumonia in children.

Objective:To explore the efficacy of a flat ground exoskeleton robot in improving the walking ability of stroke survivors.Methods:Fifty-eight stroke survivors with mobility difficulties were randomly divided into a robot group ( n=29) and a control group ( n=29). In addition to routine rehabilitation, the control group received conventional walking training, while the robot group underwent exoskeleton robot-assisted gait training. The 30-minute training sessions were held twice a day, 5 days per week for 5 weeks. Before as well as after 2 and 4 weeks of treatment, everyone′s walking ability was tested using the 6-minute walk test (6MWT) and functional ambulation scale (FAC). General lower limb motor function was quantified using the Fugl-Meyer Lower Extremity assessment (FMA-LE). Moreover, gait analysis was conducted before and after 4 weeks of treatment. Results:After 2 and 4 weeks of treatment, the average 6MWT times of both groups were significantly better than before the treatment, with the improvement of the robot group significantly greater than that of the control group after 2 weeks. After 2 and 4 weeks the average FMA-LE and FAC scores of both groups had improved significantly compared with before treatment. After 4 weeks the stride frequency and gait cycle of both groups had improved significantly.Conclusions:Exoskeleton robot-assisted gait training can improve walking ability and lower limb motor function of stroke survivors about as well as conventional walking training.

OBJECTIVETo investigate the effect of joint mobilization on postoperative wrist joint function, pain and grip strength for elderly patients with distal radius fracture.

METHODSFrom January 2015 to June 2016, a total of 67 elderly patients with distal radius fracture were randomly divided into routine exercise group and joint mobilization group. Among them, 37 patients in the routine exercise group underwent conventional distal radius fracture postoperative joint function exercise regimen, including 16 males and 21 females with a mean age of (67.8±3.2) years old ranging from 60 to 72 years old;the injured side was dominant in 23 cases and non-dominant in 14 cases;injury mechanism was fall in 26 cases, traffic accident in 11 cases; for AO type, 6 cases were type B3, 18 cases were type C1, 7 cases were type C2, 6 cases was type C3. Other 30 patients in the joint mobilization group underwent joint mobilization on the basis of the routine exercise group including 14 males and 16 females with a mean age of (67.1±4.0) years old ranging from 61 to 74 years old; the injured side was dominant in 21 cases and non-dominant in 9 cases;injury mechanism was fall in 25 cases, traffic accident in 5 cases;for AO type, 8 cases were type B3, 13 cases were type C1, 6 cases were type C2, 9 cases were type C3. The wrist joint activity, Gartland-Werley wrist joint function score, VAS pain score and grip strength were observed at 3 months afrer treatment.

RESULTSAfter 3 months' treatment, the VAS in the routine exercise group was higher than that of the joint mobilization group (<0.05). The grip strength of affected side in both groups were lower than that of contralateral side, but the average grip strength of affected side in joint mobilization group was higher than that in routine exercise group(<0.05). In routine exercise group, the average angle of flexion, extension, radial deviation were significantly higher than those of joint mobilization group(<0.05). But ulnar deviation angle in routine exercise group compared with joint mobilization group had no significant difference (>0.05). In the comparison of each item of Gartland-Werley, there was no significant difference between two groups in residual deformity and complication(>0.05); the average score of subjective score, objective score and total score in routine exercise group were significantly higher than those of the joint mobilization group (<0.05). The wrist function Gartland-Werley score in routine exercise group after treatment was excellent in 21 cases, good in 10, 6 in fair, while in joint mobilization group, excellent in 23, good in 6, fair in 1(<0.05).

CONCLUSIONSThe application of joint mobilization in the treatment of elderly patients with distal radius fracture can improve the joint activity and obtain better wrist function after surgery.
