OBJECTIVE To investigate present conditions about the fungal infection and analyze its risk factors and the measure of prevention. METHODS Before statistics and analysis,clinical data and culture results of 175 cases from Jan 2002 to Dec 2004 were collected. RESULTS The respiratory tract occupied the majority of the fungus infection(40.00%),the gastrointestinal tract was the second(23.43%),and the urinary tract was the third(19.43%).In infection strains,Candida albicans occupied the first place(68.57%),C.tropicalis and(C.glabrata) were the second and third(6.86% and 5.71%). CONCLUSIONS The fungal infection is relevant to some risk factors,such as using antibiotics,underlying disease and aging.Therefore,using antibiotics reasonably and improving the immunity of organism are the main measures of preventing the fungal infection.

Objective To compare the effects of isoflurane compare sevoflurane on postoperative cognitive function and the level of serum β-amyloid in elder patients at 12 months after surgery.Methods Seventy-seven patients undergoing abdominal surgery,43 males and 34 females,aged 65-75 years,ASA physical status Ⅰ-Ⅲ,were divided into two proups:isoflurane group (group Ⅰ,n =32) and sevoflurane group (group S,n =45).The patients' cognitive function were assessed using mini-mental state examination (MMSE) 1 d before operation,3 d and 12 months after opertion.Blood samples were taken before operation,3 d and 12 monthes after operation for determination of serum Aβ42 and Aβ40 concentrations.Results The MMSE scores of the two groups 3 d after operation were significantly lower than those before operation (P＜0.05).The MMSE score 3 d after operation in group Ⅰ was significantly lower than that in group S (P＜0.05).The incidence of cognitive dysfunction 12 months after operation had no significant difference between two groups [13 (40.6％) cases vs 15 (33.3％) cases].There was no significant difference in the serum Aβ42 and Aβ40 concentration between groups.Conclusion Sevoflurane has less effect on postoperative cognitive function in short time than isoflurane,but its long-term effect seemed to be similar.The levels of Aβ42 and Aβ40 showed no difference between two groups.

Objective To explore the effect of drug injection under bronchoscopy on the retreatment of smear positive cavitary pulmonary tuberculosis. Methods From June 2016 to December 2017,164 cases of pul-monary tuberculosis with smear Yang cavity type were selected,which were divided into 2 groups according to the random digital table method,each groups has 82 cases.The control group received routine treatment,the observa-tion group underwent bronchoscopy with Kangfuxin Liquid combined with drug injection therapy.The clinical effect of the two groups,the changes of lung function before and after treatment and the improvement of clinical symp-toms were compared.Results The clinical curative effect of the treatment group was better than the control group, which difference was statistically significant(P < 0.05). FEV1,FEV1/FVC,PEF index in the observation group were better than the control group,which difference was statistically significant(P<0.05).The complication rate of observation group was lower than the control group,which difference was statistically significant(P < 0.05). Conclusion Drug injection under bronchoscopy can significantly improve the clinical efficacy and lung function and promote clinical symptoms in patients with retreated smear positive pulmonary tuberculosis.It is worthy of popu-larization and application.

Objective:To explore the related factors influencing the length of hospital stay(LOS) of pregnant women with heart disease (PWHD) after cesarean section.Methods:A total of 306 patients with PWHD who underwent cesarean section from January 2012 to March 2019 were collected. Among them, 203 patients had not undergone heart surgery (uncorrected group) and 103 patients who had undergone heart surgery (corrected group) during the same period. Demographic, perioperative and postoperative data were recorded. Predictors associated with postoperative LOS were determined using univariate and multivariate linear regression analysis models.Results:(1) The median LOS after cesarean section in the uncorrected group was 6 days (5-8 days). The results of univariate linear regression analysis showed that 38 parameters had significant impact on LOS ( P<0.05). The results of multivariate linear regression analysis showed that 5 parameters were independent risk factors for prolonged LOS in the uncorrected group; among them, the median LOS in uncorrected group with hypertensive disorders of pregnancy was 3 days longer than that in patients with PWHD alone [7 days (5-8 days) vs 4 days (4-5 days), β=0.195, P=0.001]; the median LOS in uncorrected group with high serum creatinine was 3 days longer than normal patients [7 days (5-13 days) vs 4 days (4-5 days), β=0.145, P=0.015]; the LOS of patients who chose general anesthesia was 2 days longer than that of patients who chose spinal anesthesia [6 days (4-8 days) vs 4 days (4-5 days), β=0.154, P=0.007]; the LOS of patients with postoperative pulmonary infection was 4 days longer than that of patients without pulmonary infection [8 days (5-15 days) vs 4 days (4-5 days), β=0.269, P<0.01]; the LOS of patients who admitted to ICU after surgery was 2 days longer than that not admitted patients [6 days (5-8 days) vs 4 days (4-5 days), β=0.268, P<0.01]. (2) The median LOS after cesarean section in corrected group was 4 days (4-5 days). The results of univariate linear regression analysis showed that 8 parameters had significant impact on the LOS (all P<0.05). The results of multivariate linear regression analysis showed that 2 parameters, which were American Society of Anesthesiologists (ASA) grade ( β=0.198, P=0.028) and intraoperative blood loss ( β=0.285, P=0.003), were the independent risk factors for prolonged LOS in corrected group. Conclusion:Preoperative with hypertensive disorders of pregnancy, preoperative creatinine increase, intraoperative general anesthesia, postoperative pulmonary infection, and postoperative admission to ICU are independent predictors of prolonged LOS in uncorrected patients with PWHD; ASA classification and intraoperative bleeding are independent predictor of prolonged postoperative LOS in patients with corrected PWHD.

From September 2017 to February 2018, 650 disabled children and adolescents aged 6-to 17-year-old in Beijing were matched 1∶1 to those in normal physical condition with same age, gender and place of residence. All children and adolescents were investigated for self-injury status in the last year to understand the difference of self-injury incidence between groups. Multivariate unconditional logistic regression model was applied for exploring relevant factors of self-injury of children and adolescents. This study found that the disability, insufficient sleep, difficulty falling asleep, and sleeping late were associated with self-injury of children and adolescents.

Objective: To investigate the incidence and risk factors of postoperative acute renal injury (AKI) in patients after primary unilateral hip and knee replacement. Methods: Between January 2016 and July 2018, A total of 1 490 patients underwent hip and knee arthroplasty were enrolled. There were 507 male and 983 female with a median age of 66 years (range: 18 to 95 years). There were 201 patients underwent femoral head replacement, 897 total hip arthroplasty and 392 total knee arthroplasty, respectively. The creatinine value was 68.79 μmol/L preoperatively. Demographic, perioperative and postoperative data were recorded. The development of AKI was defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The demographic information, comorbidities, preoperative medication, type of surgery, type of anesthesia, intraoperative anesthetics, operation time, intravenous fluid type and dose, amount of bleeding and postoperative creatinine values were recorded. Predictors associated with AKI and postoperative creatinine was determined by multiple regressions. Results: There were 80 cases developed AKI with the incidence of AKI 5.4%. Among the AKI patients, there were 69 cases (4.6%) in AKI stage 1, 7 cases (0.5%) in AKI stage 2, and 4 cases (0.3%) in AKI stage 3. The creatinine value was 72.03 μmol/L after surgery. The length of postoperative hospital stay was 9 days. There were 5 patients died in hospital. The independent risk factors of AKI after hip and knee arthroplasty included old age, a higher American Society of Anesthesiologists (ASA) grade and preoperative diabetes (P<0.05). The risk of postoperative AKI in patients aged 60-69 years, 70-79 years, and older than 80 years was 2.259, 2.798, and 6.049 times than that of patients under 60 years of age, respectively. The risk of postoperative AKI in patients with ASA grade II, III, and IV was 3.749, 9.023, and 21.595 times than that of ASA grade I patients, respectively. The risk of AKI in patients with diabetes before surgery was 2.377 times higher than that in non-diabetics. Age, diabetes, hypertension and preoperative serum creatinine were positively correlated with postoperative creatinine values (P<0.05). Intensive care unit admissions were greater in AKI patients than that in non-AKI patients (25.0%, 5.6%, χ²=-6.774, P<0.001). Compared with non-AKI patients, the postoperative length of hospital stay was longer in AKI patients (Z=-3.904, P<0.001). Conclusion The incidence of postoperative AKI after primary hip and knee replacement was 5.4%. The older age, ASA grade, and diabetes were independently associated with risk of AKI. Old age, male, preoperative diabetes, hypertension and a higher preoperative creatinine value can predict postoperative increased creatinine levels at postoperation. The risk factors for AKI included old age, a higher ASA grade and diabetes. The postoperative length of hospital stay was longer in AKI patients.
