Objective:To investigate the clinical data, drug resistance and treatment prognosis of Cryptococcus neoformans isolated from patients with acquired immunodeficiency syndrome(AIDS) in a hospital in Shanghai. Methods:The clinical data of AIDS patients with Cryptococcus neoformans infection in Shanghai Public Health Clinical Center from January 2014 to December 2023, and the drug sensitivity to 5 antifungal drugs in vitro, treatment and prognosis were retrospectively analyzed. Results:From January 2014 to December 2023, there were 295 AIDS patients with Cryptococcus neoformans infection in our hospital, with 255 males and 40 females. CD4 + T lymphocyte counts ≤100 cells/μl were detected in 251 patients. A total of 384 strains of Cryptococcus neoformans were isolated from the 295 patients, with the highest detection rate in cerebrospinal fluid samples (65.9%, 253/384), followed by blood samples (29.4%, 113/384). The sensitivity of 384 strains of Cryptococcus neoformans to 5-fluorocytosine was the highest (98.5%, 379/384), followed by fluconazole (95.6%, 367/384) and amphotericin B (95.3%, 366/384). After treatment against cryptococcal infection, 252 patients (86.0%, 252/293) were discharged and 20 patients (6.8%, 20/293) died. The other 2 cases were not treated for cryptococcal infection. Conclusions:As Cryptococcus neoformans is an important pathogen of AIDS patients, clinicians should actively carry out laboratory examination of Cryptococcus and rational drug use according to the results of drug sensitivity test, while alert to the occurrence of drug resistance.

Objective To analyze the current status of occupational health literacy (OHL) among front-line workers in the metal products industry and to explore its influencing factors. Methods A total of 5 193 front-line workers from the metal products industry in 14 prefecture-level cities in Guangdong Province were selected as the research subjects by the stratified cluster random sampling method. The Occupational Health Literacy Questionnaire of National Key Populations was used to assess their OHL levels. To analyze the influencing factors of OHL, binary logistic regression analysis was conducted. Results The overall OHL level among the participants was 40.0% (2 079/5 193). The result of binary logistic regression analysis showed that workers with lower educational level, lower average monthly personal income, and smaller enterprise size had lower OHL levels (all P<0.01). In addition, workers in foreign-funded enterprises had higher OHL levels than those in private enterprises (P<0.01). Conclusion There remains considerable room for improvement in OHL among front-line workers in the metal products industry. Priority focus is to improve OHL among workers with lower education and income levels, as well as those employed in private and micro- or small-sized enterprises.

Objective:To evaluate the effect of controlled low central venous pressure (CLCVP) induced by milrinone on intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy.Methods:Eighty American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, regardless of gender, scheduled for elective laparoscopic hepatectomy, with body mass index of 18-30 kg/m 2, aged 18-64 yr, were divided into 2 groups ( n=40 each) by a random number table method: nitroglycerin group (X group) and milrinone group (M group). After the start of surgery, milrinone 0.5 μg·kg -1·min -1 was continuously infused in group M and nitroglycerin 0.5-1.5 μg·kg -1·min -1 was continuously infused in group X to maintain central venous pressure (CVP)<5 cmH 2O. Norepinephrine 0.01-0.10 μg·kg -1·min -1 was intravenously injected during operation to maintain mean arterial pressure at 60-90 mmHg. Norepinephrine 8-16 μg was intravenously injected when necessary. At 10 min after tracheal intubation (T 1), after establishment of pneumoperitoneum (T 2), at 5 and 30 min after CVP reached the target value (T 3, T 4), at 5 min after CVP returned to normal value (T 5) and at the end of surgery (T 6), the internal carotid artery mean blood flow velocity, internal carotid artery blood flow, cardiac output, and cardiac index were recorded. The surgical field score, consumption of intraoperative norepinephrine, fluid input and output, and occurrence of adverse reactions at 7 days after operation were recorded. Results:Compared with group X, the cardiac output, cardiac index, internal carotid artery mean blood flow velocity and internal carotid artery blood flow were significantly increased, the consumption of intraoperative norepinephrine was decreased, and the surgical field score was increased at T 3-5 in group M ( P<0.05). There was no significant difference in the intraoperative fluid intake and output and incidence of postoperative adverse reactions at each time point between the 2 groups ( P>0.05). Conclusions:Compared with nitroglycerin-induced CLCVP, milrinone-induced CLCVP can improve the reduction in intraoperative cerebral blood flow in the patients undergoing laparoscopic hepatectomy to some extent.

Objective To systematically assess the efficacy and safety of acupuncture in treating type 2 diabetes.Methods Related literature was retrieved with a computer. After the data were sifted out from the literature according to the established criteria, they were collected and crossly checked by two researchers independently. The data were input to RevMan5.2 for statistical analysis. Results A total of ten studies were included with a total of 743 patients. The results of Meta analysis showed 1) Post-treatment total efficacy rate was higher in the acupuncture or combined acupuncture and medicine group than in the control group [OR=3.60, 95%CI (2.11,6.13)] and there was a statistically significant difference (Z=4.71,P<0.00001); 2) Post-treatment range of decrease in fasting blood glucose (FBG) was significantly higher in the experiment group than in the control group [WMD=-1.20,95%CI (-1.38,-1.02)] and there was a statistically significant difference (Z=12.88,P<0.00001); 3) Post-treatment range of decrease in 2-h postprandial blood glucose (2hPBG) was significantly higher in the experiment group than in the control group [WMD=-1.27, 95%CI (-1.47,-1.06)] and there was a statistically significant difference (Z=12.02,P<0.00001).Conclusion Clinically acupuncture or combined acupuncture and medicine is more effective than Chinese herbal medicine or Western medication alone in treating T2DM and has no toxic and side effects.
