Objective:To investigate the drug resistance of newly diagnosed HIV-1 infected patients in Shanghai and to provide reference value for clinical antiretroviral therapy (ART).Methods:The peripheral venous blood plasma of 196 newly diagnosed HIV-1 infected patients screened according to the inclusion and exclusion criteria at the Shanghai Public Health Clinical Center from April to June 2023 was collected, HIV-1 RNA was extracted, the pol region was amplified by reverse transcription-polymerase chain reaction (RT-PCR) for sequencing, the mutation sites and ART drug resistance were analyzed.Results:The plasma of 196 newly diagnosed HIV-1 infected patients was amplified successfully in 162 cases (amplification success rate was 82.65%). The subtypes consisted of CRF07_BC(51.23%), CRF01_AE (27.78%), and others (6.79%), CRF55_01B (5.56%), B (3.70%), CRF01_AE/B (3.70%) and CRF08_BC (1.23%). The overall transmitted drug resistance rate was 7.41%, the protease inhibitors (PIs), non-nucleoside/nucleotide reverse transcriptase inhibitors (NNRTIs), nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), integrase inhibitors (INSTIs) resistance rates were 3.09%, 3.70%, 0.00% and 0.62%, respectively. The proportion of NNRTIs-related mutation sites in B (66.67%) and CRF55_01B (88.89%) was higher than that in CRF07_BC (13.25%); the proportion of NNRTIs-related mutation sites in CRF55_01B (88.89%) was higher than that in CRF01_AE (22.22%) and other subtypes (18.18%), the difference was statistically significant (all P<0.05). Multivariate logistic regression analysis showed that the probability of PIs-related mutation sites in CRF01_AE/B was 21.71 times that of CRF07_BC[odds ratio ( OR)=21.71, 95% confidence interval ( CI): 3.36-140.27, P=0.001]. Conclusions:The transmitted drug resistance among newly diagnosed HIV-1 infected patients in Shanghai is at the moderate epidemic level, mainly NNRTIs and PIs-related drug resistance, and the INSTIs resistance rate is low, the use of INSTIs in ART regimens should be considered.

Autoimmune disease is a kind of disease characterized by immune imbalance,abnormal activation of immune cells,massive production of inflammatory factors and immune complexes,which leads to the damage of multiple organs and systems.Autoimmune disease is easy to recur in clinical practice.The previous studies showed that there is a correlation between dampness syndrome in traditional Chinese medicine(TCM)and immune dysfunction.This paper explains the theoretical basis for the correlation between dampness syndrome of TCM and the recurrence of autoimmune diseases,and the similarities between the two in macro appearance,pathogenesis characteristics,etc.,analyzes the possible correlation about biological mechanism between dampness syndrome and autoimmune diseases,and discussed the correlation between pathogenic dampness of TCM and the recurrence of autoimmune diseases such as psoriasis,rheumatoid arthritis,ulcerative colitis,and nephrotic syndrome.It is pointed out that pathogenic dampness of TCM is an important pathogenic factor for the recurrence of autoimmune diseases,and is closely related to the recurrence of autoimmune diseases.Autoimmune diseases can be treated from the perspective of pathogenic dampness in TCM,and therapy of invigorating spleen,replenishing qi and removing dampness is frequently adopted,which is beneficial to alleviating the clinical symptoms of patients and reducing the recurrence of autoimmune disease.

Parotid hypertrophy is a non-neoplastic, non-inflammatory and chronic salivary gland enlargement, which leads to facial "swelling", especially in the lower and lateral parts of the face, weakens the aesthetic feeling, and adversely affects the mental health of patients to a certain extent. However, there is no standard clinical treatment. In recent years, studies have explored and confirmed that botulinum toxin type A injection showed a good clinical effect in the treatment of parotid hypertrophy. With the aim of providing reference for the clinical treatment, the review summarize the potential mechanism, methods and complications of botulinum toxin type A treating parotid hypertrophy.

Empty follicle syndrome (EFS), defined by the failure to retrieve oocytes despite normal follicle development following controlled ovarian stimulation, is a multifactorial condition in assisted reproductive treatment and categorized into genuine EFS (GEFS) and false EFS (FEFS). The etiology of GEFS is complex, involving genetic factors and ovarian dysfunction, with mutations in LHCGR and ZP genes being the major causes. However, the underlying cause remains unknown in most patients. Targeted therapies based on specific etiologies are crucial in GEFS management. Oocyte donation is considered as a final viable option when other precision treatments prove ineffective. The etiology of FEFS is relatively clear, primarily associated with inappropriate administration of ovulation-triggering drugs, which can be rescued by a second injection of human chorionic gonadotropin or change the medication regimen. This review summaries current advances in the diagnosis and treatment of EFS, aiming to provide guidance for clinical management and further etiology research.

ObjectiveTo investigate the status, characteristics of population distribution and trends of chronic obstructive pulmonary disease (COPD) deaths among the registered residents in Chongming District, Shanghai from 2002 to 2022, and to provide a scientific basis for precise prevention and control of COPD. MethodsCOPD death data were obtained from the Shanghai Chongming District Death Surveillance System, and indicators such as crude mortality rate, standardized mortality rate, mortality rate by age group, and probability of premature death were calculated for the registered residents with COPD. Joinpoint 5.0.2 software was adopted to analyze the annual percent change (APC) and average annual percent change (AAPC), followed by an analysis of trend changes. ResultsFrom 2002 to 2022, the average annual crude mortality rate and average annual standardized mortality rate of COPD among the residents of Chongming District were 73.49/100 000 and 34.00/100 000, respectively, and both were higher in males than those in females. The crude mortality rate of COPD among the residents aged ≤69 years in Chongming District was 6.78/100 000, followed by 218.28/100 000 in the age group of ≥70 years and 1 042.77/100 000 in the age group of ≥80 years, respectively. The standardized mortality rates for the whole population (AAPC=-9.75%), males (AAPC=-9.06%) , and females (AAPC=-12.25%) all showed a downward trend (all P<0.001). In addition, there was a decreasing trend in the crude mortality rates for the residents aged ≤69 years (AAPC=-7.51%), aged ≥70 years (AAPC=-9.89%), and aged ≥80 years (AAPC=-8.85%) (all P<0.001). Furthermore, the probability of premature death of COPD decreased from 1.45% in 2002 to 0.08% in 2022. ConclusionThe mortality rate and probability of early premature death of COPD among the registered residents in Chongming District, Shanghai from 2002 to 2022 show a downward trend, and the mortality rate of declining in males is slower than that in females. The elderly with advanced age account for the highest number of deaths. Therefore, targeted intervention measures should be taken for key groups to reduce the mortality rate of COPD.
