Objective To study the association between mean platelet volume(MPV),platelet distribution width(PDW)and procalcitonin(PCT)and cardiac function in patients with pulmonary hypertension(PH)and their diagnostic value on heart failure.Methods 103 patients with PH(PH group)in the 3rd People's Hospital of Chengdu from October 2021 to October 2022 and 103 healthy subjects with physical examination(control group)were selected as study subjects.Fasting peripheral venous blood was collected on the 1st day of admission and MPV,PDW and PCT were detected.The left ventricular ejection fraction(LVEF)was measured and the cardiac function was evaluated by New York Heart Association(NYHA)grading criteria.The patients with PH were divided into failure group and non-failure group according to the diagnosis results of heart failure.The relations of MPV,PDW and PCT with cardiac function in patients with PH and the diagnostic value on heart failure were analyzed.Results The levels of MPV,PDW,and PCT were all higher in the experimental group compared to the control group,while the LVEF was lower,and these differences were statistically significant(P<0.05);as the NYHA classification increased,the levels of MPV,PDW,and PCT showed an increasing trend,while LVEF showed a decreasing trend,and the differences between the groups were statistically significant(P<0.05);in the heart failure group n = 65,the levels of MPV,PDW,and PCT were higher compared to the non-heart failure group n = 38,while LVEF was lower,and these differences were statistically significant(P<0.05).The levels of MPV,PDW,and PCT werr signifi-cantly positively correlated with NYHA functional classification and LVEF(P<0.05).The levels of MPV,PDW,and PCT had good reference value for the diagnosis of heart failure in PH patients,with AUC values of 0.816,0.897,and 0.825 respectively,and the combined diagnostic AUC is 0.952,which wass statistically different from the application of the three indicators alone(P<0.05).Conclusion RDW,PDW and PCT are closely related to cardiac function in patients with PH,and can provide reference information for diagnosis and treatment of heart failure in patients with PH.

Objective:To explore the clinical efficacy, recurrence rate, and quality of life of elderly patients with Qi deficiency constipation treated with umbilical moxibustion combined with stone needle acupoint massage.Methods:Convenience sampling method was used to select 160 elderly patients with qi deficiency constipation who were hospitalised in the Department of Respiratory Medicine of Dongfang Hospital, Beijing University of Chinese Medicine, Xiyuan Hospital of China Academy of Chinese Medical Sciences, and Guang'anmen Hospital, China Academy of Chinese Medical Sciences from June 2021 to January 2023 as the study subjects. A total of 160 elderly patients with Qi deficiency constipation were randomly divided into four groups by using the method of randomisation of district groups, the control group ( n=40) received routine health education and nursing, the massage group ( n=40) was treated with needle stone acupoint massage, the umbilical moxibustion group ( n=40) received umbilical moxibustion with moxa and ginger, and the massage and umbilical moxibustion group ( n=40) was treated with needle stone acupoint massage combined with umbilical moxibustion. All patients were treated continuously for two weeks. This study compared the clinical efficacy, constipation symptom score, traditional Chinese medicine syndrome score, score of Patient Assessment of Constipation-Quality of Life (PAC-QOL) and the recurrence rate after three months of treatment among four groups of patients. Results:After treatment, compared with the other three groups, the massage and umbilical moxibustion group had the highest total clinical effective rate, with the lowest scores for constipation symptoms, traditional Chinese medicine syndromes, and PAC-QOL, with statistical differences ( P<0.05). There was a statistically significant difference in the recurrence rate among the four groups ( P<0.05) . Conclusions:Needle stone acupoint massage and umbilical moxibustion can both improve the clinical symptoms of elderly patients with Qi deficiency constipation, and combination of the two has a better effect, reducing recurrence rate, and improving quality of life.

Background:This study aimed to investigate the changes in the clinical indicators and influencing factors of treatment duration among human immunodeficiency virus (HIV) patients in whom antiretroviral therapy (ART) was unsuccessful.Methods:In this retrospective study,a total of 9,418 HIV patients who failed in ART during 2004-2016 were included and divided into two treatment groups-Group 1 (treatment time ≤ 3 years,n1 =5,218) and Group 2 (treatment time ＞ 3 years,n2 =4,200).Patient follow-up data,including age,cluster of differentiation 4 (CD4) count,and viral load,glucose,creatinine,and triglyceride levels,were extracted from electronic health record databases.Covariance analysis for repeated measures was used to analyze the biochemical indicators,and multiple logistic regression modeling was used to compare relevant data extracted from the Group 1 and Group 2 HIV patient cohorts with different treatment time.Results:The median initial CD4 count was 175.0 cells/μl (interquartile range,77.0-282.0),while the initial CD4 counts for Group 1 were lower than those for Group 2 (P ＜ 0.05).A significant interaction between group and time effects was observed (P ＜ 0.05) in total cholesterol (TC).Changes in hemoglobin level among HIV patients were also significantly associated with treatment time (P =0.001).The initial CD4 count (odds ratio [OR] =0.756),female sex (OR =0.713),Zerit (d4T) (OR =1.443),TC (OR =1.285),and aspartate aminotransferase level (OR =1.002) were significantly associated with the survival time of dead patients with HIV (P ＜ 0.05).Additionally,the initial CD4 count (OR =1.456),age (OR =1.022),time interval (OR =0.903),patient's living status (OR =0.597),d4T (OR =2.256),and triglyceride (OR =0.930) and hemoglobin levels (OR =0.997) were significantly associated with the treatment time of HIV patients with drug withdrawal (P ＜ 0.05).Conclusion:The initial biochemical parameters can affect the survival and treatment time of HIV patients.With a comprehensive understanding of the physiological and biochemical indicators of patients,we can reduce the probability of drug withdrawal and prolong the survival time of HIV patients.

Objective To explore the related factors of diarrhea onset in critically ill patients during early enteral nutrition (EEN). Methods Thirty Zhejiang Provincial Emergency Intensive Care Units (EICU) and ICU to implement EEN support for critically ill patients from July 2016 to August were enrolled, and the incidence of diarrhea within 1 week after EEN administration was observed. The patients were divided into a diarrhea group and a non-diarrhea group according to whether diarrhea occurred or not during EEN. The basic status data [sex, age, body mass index (BMI), albumin, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), nutritional risk screening (NRS2002), major disease diagnosis], and EN status (feeding route, infusion method, EN type, amount of EN on days 4 and 7), and clinical treatment (applying following treatments or not: mechanical ventilation and its duration, vasoactive drugs, gastrointestinal motility drugs, probiotics) and clinical outcomes (survival after discharge or not) were collected in two groups. Multivariate Logistic regression analysis was performed on the indexes with statistically significant differences obtained from the univariate analysis to screen out the relevant risk factors of occurrence of diarrhea in critically ill patients during EEN administration. The receiver operating characteristic curve (ROC) was drawn to analyze the predictive value of each risk factor for occurrence of diarrhea in critically ill patients with EN therapy. Results Of the 510 critically ill patients who underwent EEN, 156 had diarrhea, 70.5% (110/156) had diarrhea within 4 days of EEN, most diarrhea lasts for 3 days and most frequency of diarrhea was 3-4 times a day. The univariate analysis showed that the age of patients in the diarrhea group was significantly higher than that in the non-diarrhea group (years:69.42±17.94 vs. 65.76±17.69), the mechanical ventilation time and ICU hospitalization time were significantly longer than those of non-diarrhea group [mechanical ventilation time (days): 8 (5, 14) vs. 8 (4, 9), ICU hospitalization time (days): 11.5 (8.0, 19.0) vs. 9.0 (6.0, 14.0)], the proportion of probiotics used and the proportion of feeding by nasal tube were significantly higher than those of non-diarrhea group [proportion of probiotics: 26.9% (42/156) vs. 14.4% (51/354), proportion of nasal tube feeding: [26.9% (42/156) vs. 14.4% (51/354)]. Multivariate Logistic regression analysis showed that the use of probiotics was a protective factor for diarrhea during EEN in critically ill patients [odds ratio (OR) = 0.447, 95% confidence interval (95%CI) = 0.273-0.730, P = 0.001]. ROC analysis showed that the area under the curve (AUC) of probiotics predicting diarrhea was 0.598 (95%CI = 0.554-0.640), P < 0.001, sensitivity was 35.9%, and because AUC was less than 0.7, the accuracy and sensitivity of predicting diarrhea with probiotics was considered to be relatively poor. Conclusion The incidence of diarrhea is high in EEN in critical illness patients and its occurrence is related to various factors. The addition of probiotics can reduce the incidence of diarrhea.

Background: The rate of death among people living with HIV/AIDS has decreased significantly as a result of treatment with highly active antiretroviral therapy (HAART). However, the issues of drug induced toxicities and complexity of current HAART regimens has remained of great concern. The aim of this study was to determine factors influencing antiretroviral regimen changes among people living with HIV/AIDS in China. Methods: This retrospective study collected data through face-to-face interviews with people living with HIV/AIDS who were receiving HAART, and gathered relevant information from infectious disease hospitals. The following information were collected: social-demographic characteristics, antiretroviral therapies, CD4 cell counts, virus loads, reasons for changing medication and other related data. Mean and percentages were used to describe the frequency of regimen change among patients, and binary logistic regression was employed to test the factors influencing regimen change. Results: 1,123 people who had experienced regimen change were included in the analysis. On average, patients remained on HAART for 10.2 months before changing regimen, and the average CD4 cell count and viral load (VL) were 383.1 cells/μl and 28,132.4 copies/mL respectively when changing regimen. The reasons for modification were determined as treatment failure (52.5％), adverse reactions (32.3％), and other reasons including pregnancy (15.2％). There are significant differences in regimen change among people with different genders (P<0.001), modes of transmission (P<0.001), duration of HAART (P<0.001) and initial CD4 cell counts (P=0.0024). Males, drug users, people taking long-term medication, and those with lower initial CD4 counts when starting HAART tend to change regimen. Conclusion: Treatment failure was the main reason for the change of HAART regimen. Males, drug users, people on long-term medication and those with lower initial CD4 cell counts when starting HAART were most likely to change regimen.

Objective:To explore the efficacy of etanercept combined leflunomide to treat ankylosing spondylitis (AS) and its safety.Methods:90 cases with AS patients admitted in our hospital from June 2016 to January 2015 were selected.The patients were divided into observation group and control group by random number table method,45 cases in each group.Observation group was treated with etanercept combined with leflunomide,the control group were treated by leflunomide only.Morning stiffness time,AS activity index (BASDAI),AS measurement index (BASMI) were recorded before and after treatment in two groups,the total effective rate and adverse reaction were compared between the two groups.Results:After treatment,the BASDAI and morning stiffness time,BASMI of two groups of patients compared with before treatment were decreased,and the indexes above of the observation group were significantly lower than the control group,the difference was statistically significant (P＜0.05);The effective rate of the observation group was significantly higher than that of the control group,the difference was statistically significant (P＜0.05);During the course of treatment,the main adverse reactions occurred in patients with liver function damage,diarrhea and allergic skin rash,but there was no significant difference in the incidence of adverse reactions between the two groups (P＞0.05).Conclusion:Etanercept combined with leflunomide can obtain ideal effect,and low incidence rate of adverse reaction,it is worth popularizing in clinical use.

Objective To explore the effect of TCM external treatment on the patients with hyperplasia of mammary glands by meta-analysis.Methods Literatures about TCM external treatment on the patients with hyperplasia of mammary glands that were published on domestic or international magazines were extensively solicited and assessed with uniform effect criteria. The total number and valid number of patients in these literatures were counted, and the literatures were also assessed and chosen by meta-analysis with Review Manager 5.3.OR values and a 95% confidence interval (CI) were calculated and consolidated.Results Finally, totally 11 literatures and 945 patients were included in our study, of which 464 received TCM external treatment, an effective rate of 89.22%, while the control group included a total of 481 patients, an effective rate of 82.33%. TCM external treatment showed the same effect on hyperplasia of mammary glands as the oral liquid of Chinese medicines, massage and acupuncture did [OR=1.91,95%CI (0.74-4.97)]. When comparing the effect of TCM external treatment and Rupixiao oral liquid on hyperplasia of mammary glands, totally 6 literatures and 509 patients were included in the study, of which 258 received TCM external treatment, an effective rate of 97.29%, while 251 patients took Rupixiao oral liquid, an effective rate of 88.45%. TCM external treatment had a significantly better effect than Rupixiao oral liquid [OR=4.52,95%CI (1.98-10.33)].Conclusions TCM external treatment has the same effect with oral liquid of Chinese medicines, massage and acupuncture, while TCM external treatment on hyperplasia of mammary glands which promotes the circulation of qi and blood and eliminates phlegm and frees channels has a significantly better effect than Rupixiao oral liquid. It suggests that in our clinical work we should treat patients based on whatever methods they can withstand so as to improve their satisfaction.

0.05).CONCLUSIONS The rising rates of the drug-resistant Uu strains may be resulted of no-standard treatments.The treatment time will be shortened and the curative effects will be better if the treatments are based on the results of the susceptibility test.

AIM: To explore the relationship between dynamic changes of population spike (PS) and morphologic alterations in hippocampal CA1 region and morphology after transient ischemia/reperfusion and the improving effects of Chinese herbs 9602. METHODS: Changes of evoking population spike ware investigated by electrical stimulating Schaffer collateral in CA1 region of hippocampal slice after ischemia/reperfusion in vivo . Apoptosis and morphologic alterations at different time points after cerebral ischemia/reperfusion were detected by using TUNEL and Nissl staining. RESULTS: The threshold voltage of CA1 region in evoking population spike increased markedly as compared with sham control. The enhancement of wave amplitude was reduced significantly after tetanic stimulation. The duration of enhancement in amplitude decreased with the passage of reperfusion. Above all were observed from 8 h after ischemia/reperfusion. They became remarkable and got to its top at 7 day after ischemia/reperfusion treatment. TUNEL positive cells were observed in hippocampal CA1 region at 8 h, got to the top at 24 h and then gradually reduced after ischemia/reperfusion. A lot of abnormal cells in CA1 region was found, and the number of pyramidal cell reduced progressively by Nissl staining after ischemia/reperfusion. Chinese herbs 9602 reduced the threshold voltage of CA1 region in evoking population spike remarkably, enhanced the wave amplitude and prolonged the duration of PS enhancement; decreased the number of TUNEL positive cell, prevented the reduction of pyramidal cell in CA1 region. CONCLUSIONS: The excitability and reactivity were decreased and there was a gradual functional disturbance of synaptic transmission in CA1 pyramidal cell and most notable changes happened at 7 d ischemia/reperfusion, suggesting that was partly due to delayed neuronal death induced by ischemia/reperfusion. Apoptosis plays an important role in the functional deficiency of CA1 region of hippocampus induced by cerebral ischemia/reperfusion. The effects of 9602 on ameliorating the excitability and reactivity of CA1 pyramidal cells relate to inhibiting apoptosis, attanuating delayed neuron death induced by ischemia/reperfusion.
