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 explore the therapeutic mechanism of electroacupuncture(EA)in treating Parkinson disease(PD)using Tandem mass tag(TMT)quantitative proteomics technology. Methods:Forty-eight PD patients were randomly divided into a control group and an observation group,with 24 patients in each group.The control group received routine drug treatment,while the observation group received EA in addition to the routine drug treatment.EA was administered for 30 min per session,3 times a week,for a total of 12 weeks.Nine patients from each group were randomly selected to provide peripheral blood serum samples before and after treatment for TMT quantitative proteomics analysis.Differentially expressed proteins between the two groups were compared,and bioinformatics analysis was performed.The screened differentially expressed proteins were validated using enzyme-linked immunosorbent assay(ELISA). Results:In the observation group,scores on the unified Parkinson disease rating scale(UPDRS),UPDRS Ⅱ,and UPDRS Ⅲ were significantly reduced after treatment(P<0.05).In the control group,these scores tended to increase,but the changes were not statistically significant(P>0.05).After treatment,the UPDRS and UPDRS Ⅲ scores in the observation group were significantly lower than those in the control group(P<0.05).The observation group showed 62 differentially expressed proteins,while the control group had 36.Compared to the control group,the observation group had 142 differentially expressed proteins.These proteins were primarily involved in the cyclic adenosine monophosphate(cAMP)signaling pathway,T helper(Th)1 and Th2 cell differentiation,ATP-binding cassette transporter,vascular endothelial growth factor signaling pathway,and high-affinity immunoglobulin E receptor(FcεRI)signaling pathway.ELISA verification indicated that after EA treatment,the levels of α-Synuclein(αSyn)and heat shock protein beta 1(HSPB1)in the observation group were significantly lower than those in the control group(P<0.05),while the regulator of G-protein signaling 10(RGS10)level was significantly higher(P<0.05). Conclusion:EA,combined with routine drug therapy,can significantly improve clinical symptoms of PD,potentially through the regulation of the cAMP signaling pathway and the contents of differentially expressed proteins of αSyn,HSPB1,and RGS10.

Objective:To investigate the impact of residual cholesterol (RC) on the progression of arteriosclerosis in individuals receiving physical examination.Methods:A cross-sectional study. Participants aged 18 years and above who underwent arteriosclerosis testing at the Health Management Center of Zigong Fourth People′s Hospital from January to December 2023 were selected as the subjects of the study. A total of 9 016 subjects were included in this study, of whom 6 213 were considered to have arteriosclerosis. The physical examination conclusions, basic information (age, gender, body mass index, waist circumference, blood pressure, history of hypertension, history of smoking and drinking), and biochemical indicators (lipids, fasting blood glucose, liver and kidney function) were extracted in those individuals. Based on the examination results, the subjects were categorized into arteriosclerosis and normal groups. The RC levels of the participants were calculated using a formula and then the subjects were categorized into binary and quartile RC groups. Additionally, four regression models were used to analyze the impact of RC levels on the progression of arteriosclerosis while adjusting for various confounding factors.Results:The RC level was (0.63±0.44) mmol/L in the normal group and (0.76±0.61) mmol/L in the arteriosclerosis group. Based on level of RC, the normal group was divided into two subgroups: 652 individuals with elevated RC level and 2 241 with normal RC level. In the arteriosclerosis group, there were 2 069 individuals with elevated RC level and 4 144 with normal RC level. Grouped according to quartiles of RC level, the number of individuals with RC in the Q1-Q4 interval in the normal group was 838 (28.97%), 752 (25.99%), 760 (26.27%), and 543 (18.77%), respectively, showing a gradual decreasing trend. The number of individuals with RC in the Q1-Q4 interval in the arteriosclerosis group was 1 414 (22.76%), 1 438 (23.15%), 1 589 (25.58%), and 1 771 (28.51%), respectively, showing a gradual increasing trend. The difference between the groups was statistically significant ( P<0.05). After adjusting for various factors by four regression models, it was found that elevated RC levels increased the risk of arteriosclerosis progression, with a odds ratio ( OR) of 1.381, 1.242, 1.233, and 1.214, respectively. Additionally, individuals in the Q4 RC level quartile had 1.502, 1.318, 1.311, and 1.284-times higher risk of arteriosclerosis progression when compared to those in the Q1 quartile. Conclusion:The impact of RC on the progression of arteriosclerosis tend to stabilize and remain consistent, indicating that elevated RC is an independent risk factor for the progression of arteriosclerosis.

Insomnia disorder is a common disease in acupuncture clinics.There is a tendency for the theory to solidify and lag behind the clinic.In this paper,we examined insomnia disorder from the perspective of acupuncture and moxibustion theory.Based on the general law of acupuncture and moxibustion to recognize the disease,we concerned that the basic understanding of the disease has commonality between ancient and modern medical practitioners,and the theory can be deconstructed as follows:the theory of"yin and yang"is the starting point and the root of the theory,the theory of"spirit regulars the sleep"is the directly related theory,the theory of internal organs is the basis of the disease mechanism,the theory of meridians and acupoints is the key to diagnosis and treatment,and the theory of acupuncture and moxibustion is the key to treatment.The improvement and development of the theory of acupuncture for insomnia disorder can be carried out on this basis.

The ongoing pandemic of Coronavirus disease 19 (COVID-19) is caused by a newly discovered β Coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). How long the adaptive immunity triggered by SARS-CoV-2 can last is of critical clinical relevance in assessing the probability of second infection and efficacy of vaccination. Here we examined, using ELISA, the IgG antibodies in serum specimens collected from 17 COVID-19 patients at 6-7 months after diagnosis and the results were compared to those from cases investigated 2 weeks to 2 months post-infection. All samples were positive for IgGs against the S- and N-proteins of SARS-CoV-2. Notably, 14 samples available at 6-7 months post-infection all showed significant neutralizing activities in a pseudovirus assay, with no difference in blocking the cell-entry of the 614D and 614G variants of SARS-CoV-2. Furthermore, in 10 blood samples from cases at 6-7 months post-infection used for memory T-cell tests, we found that interferon γ-producing CD4

Objective:To understand the genotyping and molecular epidemiological characteristics of Norovirus (NoV) GⅡ in adult acute gastroenteritis outpatients in Shanghai from 2015 to 2016.Methods:A total of 912 stool specimens from adult patients with acute diarrhea from March 2015 to December 2016 (431 in 2015 and 481 in 2016) were collected. The Norovirus GⅡ type was detected by one-step quantitative reverse transcription PCR assay and the RdRp region of open reading frame (ORF) 1 and 5′end of ORF2 were amplified. The region was sequenced and classified.Results:From March 2015 to December 2016, NoV GⅡ were detected in 17.76% (162/912) of the samples, 15.08% (65 /431) in 2015 and 20.17% (97/481) in 2016. Based on sequence analysis of the RdRp and capsid sequences, 145 identified NoV strains were divided into 10 genotypes: GⅡ.Pe_GⅡ.4 Sydney 2012 (60), GⅡ.P17_GⅡ.17 (45), GⅡ.P16_GⅡ.13 (10), GⅡ.P12_GⅡ.3 (10), GⅡ.P7_GⅡ.6 (9), GⅡ.P21_GⅡ.21 (5), GⅡ.P16_GⅡ.4 Sydney 2012 (2), GⅡ.Pe_GⅡ.17 (2), GⅡ.P2_GⅡ.2 (1), and GⅡ.P7_GⅡ.14 (1).Conclusions:The main epidemic NoV GⅡ genotype in Shanghai was GⅡ.P17_GⅡ.17 in the spring of 2015. GⅡ.Pe_GⅡ.4 Sydney 2012 and GⅡ.P17_GⅡ.17 were identified as predominant genotypes during the winter of 2015 and spring of 2016. The most common genotype was GⅡ.Pe_GⅡ.4 Sydney 2012 in autumn of 2016. Continuous NoV outbreak surveillance is important for identifying changing trends in genotype distribution and emerging new strains.

Objective To investigate the species distribution characteristics of nontuberculous mycobacteria(NTM)in acquired immunodeficiency syndrome(AIDS)patients in Shanghai,and to provide evidences for clinical treatment.Methods A total of 775 Mycobacteria strains were isolated from patients(including 129 isolates from AIDS patients and 646 isolates from HIV-negative patients)admitted to Shanghai Public Health Clinical Center during 2015.All the species were identified by the sequence analysis of 16S rRNA gene and hsp65 gene.Differences in the species distribution were compared between patients with and without HIV infection.CD4+T lymphocyte count was detected by flow cytometry and its relation with mycobacteria infection was also analyzed.Chi-square test was used for comparison between groups.Results The ratio of NTM isolation from HIV-negative patients was 15.79%(102/646),while that was 46.51% in AIDS patients(60/129),and the difference was statistically significant(x2=61.38,P <0.01).Among the 60 NTM strains isolated from AIDS patients,mycobacterium avium-intracelluare complex(MAC)and Mycobacterium gordonae were the predominant species(43.33% and 20.00%,respectively).Moreover,five Mycobacterium colombiense strains,which were relatively rare,were also obtained.A total of 102 NTM were identified from HIV-negative patients,of which Mycobacterium gordonae(32 isolates,31.37%)and MAC(30 isolates,29.41%)were the most frequently isolated.In addition,the positive rates of NTM and MAC were significantly higher in patients with CD4+T lymphocyte counts ≤50 cells/μL(58.33% and 76.92%,respectively)than those with CD4+T lymphocyte counts>50 cells/μL(20.00% and 15.38%,respectively)(x2=4.048 and 6.524,respectively,both P<0.05).Four out of five Mycobacterium colombiense infected patients died of disseminated infections,except the remaining one whose CD4+T lymphocyte counts>50 cells/μL.Conclusions The prevalence of NTM isolation is significant higher in AIDS patients than HIV-negative patients in Shanghai,and the most prevalent NTM species is MAC.The NTM infection in AIDS patients is related with low CD4+T lymphocyte counts.

Objective This study explored the effect of the multidisciplinary-team collaborative nursing model in physical examinations of people with critical conditions (based on test results).Methods We selected 962 patients with critical conditions based on test-result values found from February to April 2018 as the general process group treated through the routine nursing model,and we also selected 1009 patients with critical conditions based on test-result values found from May to July 2018 as the multidisciplinary collaborating group using a team nursing model.The multidisciplinary collaborative nursing team members included health management center nurses,outpatient nurses,resident nurses,and ward nurses.We compared visiting rates,hospitalization rates,average visiting times,and overall satisfaction after the patients received notification of their abnormal results.There were 488 male patients (50.7％) and 474 female patients (49.3％) in the general process group,with an average age of 51.9 ± 14.9 years;there were 537 male patients (53.2％) and 472 female patients (46.8％) in the multidisciplinary collaboration group,with an average age of 51.0 ± 13.0.Results For the multidisciplinary collaboration group and the general process group,respectively,the visiting rate was 53.0％ and 44.7％ (x2=13.65);the hospitalization rate was 26.7％ and 20.9％ (x2=4.38);overall satisfaction was 97.9％ and 95.9％ (x2=6.49);and the average visiting time was 4 days and 6 days (Z=5.04).The differences were statistically significant (P＜0.05).By category,the visiting rate for radiology and ultrasound patients among the multidisciplinary collaboration group was significantly higher than in the general process group (64.4％ vs.50.8％ for radiology,45.9％ vs.37.3％ for ultrasound,x2=7.65,7.11,P＜0.05).The hospitalization rate for ultrasound patients in the multidisciplinary collaboration group was significantly higher than in the general process group (12.5％ vs.6.4％,x2=10.17,P＜0.05).The average visiting time of ultrasound,abnormal blood pressure,and laboratory testing patients was significantly lower in the general process group (4 days vs.6 days,4 d vs.7 days,4 days vs.5 days,Z=3.37,1.97,2.62,P＜0.05).The overall satisfaction of radiology patients was significantly higher than in the general process group (98.6％ vs.94.3％,x2=5.39,P＜0.05).Conclusion The multidisciplinary team collaborative nursing model improves the rate of visiting and hospitalization of patients with critical conditions after physical examination,shortening their stays,helping patients get timely diagnoses and treatment,and improving patient satisfaction,making the model worth popularizing and applying more broadly.
