ABSTRACT
Objective To understand the impact of HIV and Mycobacterium tuberculosis (MTB) co-infectious (HIV/MTB) on related mortality in Guangxi Zhuang Autonomous Region,provide evidence for the development of a better HIV/MTB co-infection control and prevention program.Methods A multiple cross-systems check (MCSC) approach was used to confirm the HIV/MTB co-infection individuals on data related to treatment,follow-up,epidemiological comprehensive and Tuberculosis (TB) special report system.Social demography characteristics,incidence of TB among HIV positive individuals,HIV incidence among MTB infection persons etc.,were described.We compared the mortalities and related risks between HIV/MTB co-infection and mono HIV positive individuals as well as between the HIV/MTB co-infection and mono MTB infection persons,using both the Chi Square test and the Cox's proportional hazard regression model (Cox).Results Reported data showed that the incidence of MTB co-infection in the HIV cohort was 17.72％ (2 533/14 293),while HIV incidence in the TB patients was 5.57％ (2 351/42 205),respectively.The mortality of HIV/MTB co-infection in the HIV/AIDS cohort was 15.16％ (384/2 533) within one-year of observation and was significantly higher than the mortality (13.63 ％,1 603/11 760) of mono HIV positive individuals (P＜0.000 1).The percentage of the HIV/AIDS death cases was 19.33％ (384/1 987) who registered and died in the 2011 calendar year were caused by MTB co-infection.Among all the HIV/MTBco-infection patients who had been identified from the HIV cohort,60.05％ (1 521/2 533) had initiated ART,15.48％ (392/2 533) had been cured for TB and 27.48％ (696/2 533) had been under complete TB regimen.Among the confirmed HIV/MTB cases from the TB cohort,the cure rate of TB was 19.70％ (463/2 351) and the percentage of completed TB regimen was 37.26％ (876/2 351).The percentage of the individuals whose CD4+ T lymphocyte cells count appeared less than 200 cell/μl was 64.13％ (785/1 224),upon the HIV diagnoses were made.Compared with individuals who were under mono HIV infection,the mortality risk on HIV/MTB co-infection was 1.17 times higher during the five-year observation period,then the patients with only mono MTB infection and the mortality risk in patients with HIV/MTB co-infection was 25.68 times higher under the 12-month observation period.Conclusions Both the incidence and mortality of HIV/MTB appeared high in Guangxi,with mortality and the risk of mortality in the HIV/MTB co-infection group significantly higher than that in both the HIV mono infection and the MTB mono infections groups.Both the rate of antiretroviral treatment coverage and the cure rate of TB treatment should be increased in no time as well as the capability of early TB case-finding among people living with HIV.

ABSTRACT
Objective To analyze the risk factors for the failure of noninvasive mechanical ventilation (NIV) in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD),and to help the clinical risk assessment and decision making.Methods A retrospective case control study was conducted.The patients with AECOPD undergoing NIV admitted to Kaifeng Emergency Center from June 2011 to March 2016 were enrolled,and they were divided into two groups according to whether NIV was successful or not within 12 hours.The nutritional status,blood gas analysis,serum electrolytes,D-dimer,renal function,serum pre-albumin,as well as kinetic vital signs,Glasgow coma scale (GCS) score,expression of respiratory distress,and spontaneous expectoration were recorded.Logistic forward stepwise regression analysis was used to analyze the factors for failure of NIV.Results 122 patients.with the initial NIV were enrolled,with NIV failure in 41 patients within 12 hours,accounted for 33.6％.Compared with NIV success group,the percents of respiratory rate ≥ 25 breaths/min (75.6％ vs.17.3％),expectoration disorders (78.0％ vs.19.8％),circulatory disorders (61.0％ vs.18.5％),malnutrition (61.0％ vs.11.1％),decreased serum pre-albumin (58.5％ vs.17.3％),and GCS score ＜ 12 (75.6％ vs.28.4％) in NIV failure group were significantly increased (all P ＜ 0.05).But there were no significant differences in gender,age,body temperature,blood gas analysis,D-dimer,serum creatinine between two groups.It was shown by the results of binary logistic regression analysis that respiratory rate,expectoration disorders,circulatory disorders,malnutrition,serum pre-albumin,and GCS score were the factors of NIV failure [odds ratio (OR) values were 10.879,6.338,9.860,23.273,8.862,6.774,and P values were 0.011,0.038,0.024,0.003,0.015,0.041,respectively].It was shown by the results of logistic stepwise regression analysis that respiratory rate ≥ 25 breaths/min,expectoration disorders,circulatory disorders,malnutrition,decreased serum pre-albumin,and GCS score ＜ 12 were independent risk factors of NIV failure (OR values were 6.610,5.403,5.138,8.153,4.979,5.100,and P values were 0.007,0.013,0.023,0.007,0.027,0.023,respectively).Conclusions The multiple independent risk factors can induce NIV failure within 12 hours in emergency patients with AECOPD,i.e.increased respiratory rate,expectoration dysfunction,circulatory disorders,malnutrition,decreased serum pre-albumin,and decreased GCS score.Emergency physicians should pay attention to these early risk factors in AECOPD patients,which can be taken as correct judgment and guide.
ABSTRACT
Objective: To investigate the expression of interleukin-4 receptor (IL-4R) in peripheral blood of patients with non-small cell lung cancer (NSCLC) before and after surgical operation and its clinical significance. Methods: The expression levels of IL-4R in peripheral blood of 84 patients with NSCLC before and after surgical operation as well as in peripheral blood of 40 healthy volunteers were measured by real-time fluorescent quantitative-PCR and ELISA. The expressionsof IL-4R in NSCLC tissues and the corresponding para-cancerous tissues were detected by immunohistochemistry. The correlations of IL-4R expression with clinicopathological characteristics and prognosis were analyzed. Results: The expression levels of IL-4R in peripheral blood of patients with NSCLC before and after surgical operation were both higher than that of healthy volunteers. The expression level of IL-4R in peripheral blood of patients with NSCLC after surgical operation was lower as compared with that before surgical operation, but which was higher than that of healthy volunteers (all P < 0.05). The positive expression rate of IL-4R in NSCLC tissues was higher than that in the corresponding para-cancerous tissues (P < 0.05). The overall survival and disease-free survival of NSCLC patients with high expression of IL-4R mRNA were poorer than those of the patients with low expression of IL-4R mRNA (both P < 0.001). Tumor stage, recurrence, metastasis and IL-4R mRNA level were independent prognostic factors of NSCLC (all P < 0.05). Conclusion: IL-4R in peripheral blood of patients with NSCLC is up-regulated, and the expression level of IL-4R is one of the independent prognostic factors of NSCLC.
ABSTRACT
Objective To understand the effect of antiretroviral therapy (ART) in reducing deaths among patients co-infected with Mycobacterium tuberculosis and human immunodeficiency virus (TB/HIV),and provide data-based evidence for improving ART in TB/HIV patients.Methods The information about TB patients who were HIV positive confirmed previously or recently in Guangxi were collected,and the TB/HIV patients were confirmed by using the related data from national AIDS prevention and treatment information system.Then a retrospective case control study was conducted to understand the survivals and deaths in the patients receiving ART or receiving no ART by using Kaplan-Meier method and estimate the ART protective rate within 1 year after TB treatment initiation.Results Among 519 TB/HIV patients,100 received ART (19.3％) ; Among 84 TB/HIV patients who died within 1 year after TB treatment,8 (9.5％) received ART,while 76 (90.5％) received no ART.Compared with the 18.7％ mortality rate in non-ART group,TB/HIV patients mortality rate in ART group was only 8.08％,the difference was statistical significant (P＜0.05).Kaplan-Meier survival curve showed that the survival rate in patients receiving ART was higher than that in patients receiving no ART within 1 year after TB treatment,the difference was statistical significant (Log-rank=4.96,P=0.02).Compared with patients receiving ART,the OR value was 2.31 times higher than that in patients receiving no ART; ART could protect 56.7％ of TB/HIV patients against death during the first year of anti-TB therapy.Conclusion In the first year of anti-TB therapy,the risk of death in TB/HIV patients receiving no ART was much higher than that in TB/HIV patients receiving ART,and the survival time was longer in the patients receiving ART.The ART coverage should be expanded in TB/HIV patients.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the predictors that reduced the survival time on HIV positive TB patients during their first year's anti-TB therapy.</p><p><b>METHODS</b>A retrospective study was conducted to review 519 TB/HIV co-infection patients from an Internet based TB surveillance system. We collected information of demography, HIV status, CD4+ lymphocytes count, antiretroviral therapy (ART), sputum smear results of diagnosis and around 2 months' initiation of anti-TB therapy, et al. Wilconxon rank sum test was used to compare the difference of age and CD4+ lymphocytes, count and Cox Uni-variable, and Multi-variable analysis were used to compare the different distribution of rest of risk elements between the groups of death and survival; survival function also has been used to evaluate the top 4 risk elements that have made negative impact on the survival time of HIV positive TB patients during their first year's anti-TB therapy.</p><p><b>RESULTS</b>Among 519 TB/HIV patients, 84 (16.18%) were dead, 435 (83.82%) survived. Median age (P50 (P25-P75)) in survival was 51.0 (41.0-65.0), while in death was 45.0 (35.0-60.0) (U=-2.68, P=0.007). There was significant difference between survival and death. Median CD4+ lymphocyte count in survival and death (P50 (P25-P75)) were 69.00 (26.00-131.20) and 114.50 (35.00-245.00), respectively, significant difference also has been observed. Based on the Cox analysis, patients with less than 2 months' intensive anti-TB therapy, poor treatment adherence, less than 4 months continue anti-TB therapy and sputum smear positive around 2 months initiation of anti-TB therapy had higher risk of death, the Relative Risk value (RR) were 1 100.40 (95% CI: 105.62-11,470.00), 52.91 (95% CI: 27.42-102.13), 49.43 (95% CI: 6.38-382.81), and 15.83 (95% CI: 2.55-98.40), respectively. Log-rank test results showed that there were significant difference between survival and death groups with anti-TB intensive therapy duration (Log-Rank value was 236.0, P<0.001), adherence (Log-Rank value was 302.9, P<0.001), and sputum smear results around 2 months' anti-TB initiation (Log-Rank value was 7.55, P=0.006).</p><p><b>CONCLUSION</b>Known HIV positive, less CD4+ lymphocyte count, not initiation of ART, sputum smear positive, around 2 months' initiation of anti-TB therapy, not enough anti-TB therapy duration of intensive and continue period and poor treatment adherence were the predictors of death of HIV positive TB patients in the first year's anti-TB therapy.</p>

Objective To understand the general feature of patients with Mycobacterium tuberculosis(MTB)and human immunodeficiency virus(HIV)co-infectious(TB/HIV)in Guangxi, from 2007 to 2012. Methods Information regarding individuals that the contributory causes of death were due to MTB infection among HIV as the underlying cause of death from the Vital Registration System,together with bacterium smear or culture results,onset of TB,time that TB was diagnosed and entered an Internet base TB surveillance system was collected and checked. Data including information on time of death,age,occupation,the underlying cause of death among TB patients, bacterium distribution,average age of death,interval from onset to death,percentage of TB/HIV co-infection patients among all the patients etc,were all analysed. Results 203 patients died from HIV associated with TB from the Guangxi Vital Registration System were identified between 2007 and 2012. The average percentage of TB/HIV co-infection cases accounted for 8.24%(ranging from 3.94%in 2007 to 13.27%in 2012)among all the deaths of HIV infection while it accounted for 9.90%(ranging from 2.56%to in 2007 to 26.88%in 2012)among patients with MTB infection in the same period. The average percentage of deaths from TB/HIV co-infection in 2010 and 2012 accounted for 10.66%(ranging from 8.83% to 13.27%) and 22.17%(ranging from 20.60% to 26.88%) among patients died of HIV and TB infection respectively. The male-female ratio was 4.21 for 1,with the average age of death as 44.65 (44.65 ± 15.52)years;median time from TB symptoms onset to diagnosis as 37(mean 94.31,standard deviation 206.07)days,record as(94.31 ± 206.07);median time from diagnosis to death as 46(165.22 ± 282.19)days,54.68%TB/HIV patients died within two months of being diagnosed with TB and the median time from TB symptoms onset to death as 131 (257.68 ± 340.79) days. 16.26% of the TB/HIV cases were bacterium confirmed TB cases. Conclusion Compare to those TB patients without HIV,less bacterium evidence was found in TB/HIV patients. High burden caused by HIV disease was seen if they were co-infected with TB. An increasing proportion of deaths was noticed among patients co-infected with HIV and TB in the last three years,suggesting that the coverage of antiretroviral therapy be scaled up together with the strengthening of the capability on early TB case-finding among people live with HIV.

Objective To observe the changes of postprandial blood pressure and heart rate with two types of nasal feeding in the very elderly and explore the method for decreasing the postprandial hypotension (PPH).Methods Totally 49 patients (aged＞80 years) were randomly divided into two groups of continuous versus intermittent nasal feeding.The clinical symptoms and changes in blood pressure and heart rate before and after meals were observed.Results The incidence of PPH was 100.0％(26 cases)in the group of intermittent nasal feeding,and 47.8％ (11 cases) in the group of continuous nasal feeding (P＜0.01).Postprandial blood pressure in the group of intermittent nasal feeding was decreased significantly as compared with the group of continuous nasal feeding (P ＜0.05); and the heart rate was accelerated in the group of intermittent nasal feeding compared with continuous nasal feeding (P＜0.05).The incidence of serious cardio-cerebral ischemia was 7.7％ (2cases)in the group of intermittent nasal feeding.The patients had no clinical symptoms in the group of continuous nasal feeding.Conclusions Continuous nasal feeding for the very elderly with gastrointestinal nutrition can reduce the extent of the falling blood pressure and the incidence of PPH,and avoide cardiocerebrovascular events.
ABSTRACT
ObjectiveTo assess the left ventricular systolic and diastolic function in patients with type 2 diabetes mellitus(DM) using quantitative tissue velocity imaging(QTVI) ,and to provide reliable evidence for early diagnosis and prevention in diabetic cardiomyopathy.MethodsOne hundred and twenty one type 2 DM patients were divided into two DM 1 groups (61 patients without microangiopathy) and DM2 group (60 patientswith microangiopathy).Fifty normal subjects were enrolled as control group.The index of echocardiography,including the LVEF, FS and mitral peak flow velocity during early and late diastole (E/A) were measured by conventional echocardiography,and the ratio of E/A was calculated.The average peak velocities of six LV wall sites at mitral annuluses during systole, early and late diastole(MEm, MEm, MAm) were measured by QTVI, and the ratio of MEm/MAm was calculated.Results Compared with the normal group, MSm ([7.13 ± 1.42])cm/s vs.([6.49 ± 1.29]cm/s), MEm ([6.22 ± 1.39]cm/s) vs.([4.53 ± 0.94]cm/s) and MEm/MAm ([0.79 ±0.17]vs.[0.59 ± 0.19]) in DM patients were significantly decreased(F = 5.32,8.01 ,4.89 ; Ps ＜0.05).There was no significant differences among three groups in the comparisons of LVEF ([67.45 ±5.47]％),([65.91 ±4.83]％),([68.01 ±6.16]％) and FS([38.84±4.23]％,[37.82±5.43]％),([40.17 ± 4.53]％)(F = 1.89 and 2.46 respectively, P ＞ 0.05) .In addition, E/A of DM2 group (0.71 ±0.21)decreased more dramatically than DM1 and normal (0.91 ± 0.18,1.02 ± 0.24)(F = 4.71, P ＜ 0.05)ConclusionCompared with EF,FS and E/A obtained by conventional echocardiography,QTVI-derived MSm,MEm and MEm/MAm are more sensitive indexes to defect early LV dysfunction.The functional disorder appears early than microangiopathy, and the left ventricular systolic and diastolic function gets worse along with the microangiopathy.
ABSTRACT
Objective To investigate the clinical values of brain natriuretic peptide (BNP) in combination with TDI in diagnosing left ventricular hypertrophy (LVH) and impaired diastolic function in elderly hypertensive patients. Methods The 140 elderly hypertensive patients were divided into LVH group (n=69) and NLVH group (n=71). Control group consisted of 50 normal subjects. Plasma BNP level and index of echocardiography, including mitral peak flow velocity during early and late diastole (E, A), ratio of E/A, average peak velocities of six LV wall sites at mitral annuluses during early and late diastole (MEm, MAm), ratios of MEm/MAm and E/MEm were measured in all patients. The correlation of plasma BNP level with cardiac ultrasonographic findings was also examined. Results The level of BNP [(61.64±37.18)ng/L, (138. 65±30. 23)ng/L] and the ratio of E/MEm (11.3±1.83, 15.7±1.45) were significantly higher in NLVH group and LVH group than in normal group (P＜0. 05 or P＜0. 01). MEm [(6.32±0. 94)cm/s, (4.29±0. 91)cm/s]and MEm/MAm (0.76±0.19, 0.51±0. 11) were significantly lower in NLVH and LVH group than in normal group (P＜0.05 or P＜0. 01). The BNP level was negatively correlated with E/A, MEm and MEm/MAm (r=- 0. 294, r= 0. 387 and r= 0. 422, all P＜0. 01), and was positively correlated with LVMI and E/MEm (r=0.342, r=0.501, all P＜0.01). Conclusions Left ventricular diastolic function is impaired in elderly hypertension patients regardless of LVH or NLVH.Plasma BNP level in combination with echocardiography parameter is accurate to evaluate the LVHand impaired diastolic function in elderly hypertensive patients.
