Aluminum adjuvants are widely used in the field of vaccines due to their ability to induce efficient and long-lasting immune responses and good safety profile. With the development of immunology, the requirements for adjuvants have gradually increased, and traditional aluminum adjuvants can no longer meet all the needs of application. The development of novel aluminum adjuvants has become a hot research topic in order to achieve good immunity-enhancing effects and induce specific types and strengths of immune responses. This review briefly introduces the mechanism of action and safety of aluminum adjuvants, with focus on the research progress of novel aluminum adjuvants in recent years, mainly including nano-aluminum adjuvants and composite aluminum adjuvants (aluminum adjuvants compounded with immunity-stimulating molecules or delivery carriers), and a prospect of their future research direction, aiming to provide some reference for the further development and clinical application of aluminum adjuvants.

Objective:To develop and validate gas chromatographic methods for the determination of residual benzene in carbomer copolymer,carbomer homopolymer and carbomer interpolymer,to address the issues of the current method in the Chinese Pharmacopoeia in the actual detection process,such as low sensitivity and poor repeatability of benzene detection in the mixed reference solution,and to optimize and improve the current stand-ards for series of carbomer pharmaceutical excipients.Methods:Samples were separated on a column DB-624(30 m ×0.530 mm,3.00 μm)with temperature programming,the inlet temperature of 140 ℃,the detector tem-perature of 250 ℃,and the split ratio of 5∶1.The external standard method was adopted for the quantitative deter-mination of residual benzene.Results:The linearity was great across the range of 0.04-1.00 μg·mL-1(r=0.996 8),the injection precision of benzene was 6.8％(n=6),and the average recovery rate was 96.89％(RSD=8.1％,n=9).Conclusion:The gas chromatographic method established in this research is more specif-ic,with higher accuracy and precision compared to the current method in the Chinese Pharmacopoeia.This optimized method is more suitable for the determination of residual benzene content in carbomer copolymer,car-bomer homopolymer and carbomer interpolymer,providing reference and guidance for the quality management and the control of carbomer.

Objective:To evaluate the clinical efficacy of modified anterior subacromial approach plate internal fixation for three- or four-part valgus impacted proximal humeral fractures.Methods:A retrospective analysis of 35 patients treated between November 2018 and November 2021 at Fuzhou Second General Hospital was performed, including 15 males and 20 females aged 61.7±7.8 years (range: 40 to 73 years). Patients were classified under the Neer system; 17 had 3-part fractures and 18 had 4-part fractures. The modified approach accessed the fracture site via the natural interval of the deltoid anterior bundle, facilitating fracture reduction and fixation using a plate. Operative time, incision length, intraoperative fluoroscopy time, follow-up duration, Constant-Murley score, fracture healing time, visual analogue scale (VAS) for pain, and humeral neck-shaft angle were assessed. Intraoperative and postoperative complications were also recorded.Results:All patients underwent successful surgery, with an average incision length of 8.1±0.3 cm (range, 7.6-9.0 cm) and intraoperative fluoroscopy time of 6.6±0.3 seconds (3-part fractures: 6.3±0.2 s, 4-part fractures: 6.8±0.2 s, t=6.350, P<0.001). Follow-up averaged 22.1±5.8 months (range, 14-31 months). Fracture healing occurred in 11.8±1.4 weeks (range, 10-15 weeks). At the final assessment, the VAS score was 1.6±0.7 (range, 1-3), the Constant-Murley score was 89.6±2.9 (range, 84-95), and the humeral neck-shaft angle was 133.4°±3.1° (range, 128°-138°; 3-part fractures: 133.6°±3.5°, 4-part fractures: 133.3°±2.8°, t=0.288, P=0.075). No complications such as avascular necrosis of the humeral head, varus collapse of the fracture site, or axillary nerve injury were recorded. Conclusion:The modified anterior subacromial approach plate internal fixation is a minimally invasive, safe, and effective treatment for valgus impacted three- and four-part proximal humeral fractures, demonstrated by excellent surgical outcomes and absence of major complications.

Jingjin (muscle region of meridian) is a distal diagnosis and treatment system of the sinew/fascia disorders on the base of the concept of jin in TCM. Jin should be a particular palpable structure rather than a single anatomic structure with a specific distributing course. Yizhi weishu refers to a idea running through the whole process of diagnosis and treatment of sinew/fascia disorders, in which, the results, obtained by the overall observation and palpation of patient's sinew/fascia structure, are taken as the criteria of treatment. Yitong weishu (taking the sites of sensitivity or tenderness as the points) verifies this idea in practice. Under the guidance of yizhi weishu, through identifying the primary from the secondary, and regulating yin and yang, the spasticity and flaccidity of sinews/fascia can be cured and the induced diseases treated. The diagnosis and treatment system of jingjin, based on yizhi weishu, develops the original jingjin theory with vague concept involved, formulates a systematic thinking of treatment for sinew/fascia disorders and provides a new approach to clinical treatment.

Abstract: Objective To analyze the epidemic characteristics and influencing factors of school influenza-like cases in 2011-2022 in Nanchang, so as to provide reference for the prevention and control of school influenza outbreaks. 　　　Methods The epidemiological relevant data of school influenza-like cases from 2011 to 2022 in Nanchang and the pathogen test results of respiratory tract samples were collected for epidemiological and etiology analysis. Results　From 2011 to 2022, a total of 142 influenza-like cases were reported in schools in Nanchang, with a cumulative morbidity of 2 880 cases and a morbidity rate of 1.89%. A total of 1 263 samples were collected, with an overall positive influenza nucleic acid detection rate of 58.91%. The highest proportion of outbreaks occurred in 2017-2019, while the lowest incidence was in 2011-2013. Outbreaks mainly occurred from November to March of the following year (accounting for 79.58%), presenting obvious seasonal characteristics. The distribution was mainly in primary schools, accounting for 70.42% (100/142) of all outbreaks. From 2011 to 2022, all types of influenza viruses were tested, and more than 2 types of influenza viruses were prevalent each year. The dominant strains alternated between influenza A H1N1, influenza A H3N2 and Victoria lineages of type B influenza viruses. From 2011 to 2019, the influenza epidemic in schools in Nanchang showed a continuous upward trend. During COVID-19 in 2020-2022, Nanchang adopted a variety of non-drug prevention and control measures for COVID-19, and both the number of influenza epidemics in various schools and the number of influenza virus nucleic acid positive cases decreased. The average number of classes involved in the epidemic was (3±2), and the average duration of the epidemic was (8±4) days. 　Conclusions The outbreaks of influenza-like illness in Nanchang schools is highly prevalent in winter and spring, , with urban primary schools being the high incidence locations. Non-drug prevention and control measures for COVID-19 have an impact on the epidemic trend of influenza, so the continuous monitoring of the school influenza virus activities and improving the timeliness of the report will be conducive to the rapid control of the epidemic.

Objective:To investigate the efficacy of the biopsy strategy combining 6-core systematic and 3-core MRI-targeted biopsy on prostate cancer (PCa) detection in biopsy-na?ve patients.Methods:The clinical data of 121 biopsy-na?ve patients who underwent transperineal prostate biopsy in West China Hospital of Sichuan University from July 2018 to January 2020 were retrospectively analyzed. The average age was (64.7±9.1) years old. Pre-biopsy prostate-specific antigen (PSA) was (12.4±7.5)ng/ml, f/t PSA was 0.13±0.05. Prostate volume was (43.1±26.1) ml and PASD was (0.35±0.27) ng/ml 2. The prostate-imaging and data system (PI-RADS) score of MRI before biopsy was reported to be 3 for 29 patients (24.0%), 4 for 54 patients (44.6%) and 5 for 38 patients (31.8%). All 121 patients underwent 12-core systematic biopsy combined with a 3-core or 5-core MRI-targeted biopsy, of which 61 patients underwent 3-core targeted biopsy and 60 underwent 5-core targeted biopsy. There was no significant difference in the pre-biopsy clinical data between the two groups ( P>0.05). A 6-core systematic biopsy was redefined as the results of 6 cores among the 12-core systematic biopsy. We compared the detection rates among the single 12-core systematic biopsy, 6-core systematic biopsy, MRI-targeted biopsy (3-core or 5-core), and different systematic biopsy combing with targeted biopsy for any PCa and clinically significant PCa, and we also analyzed the cumulative cancer detection rates for MRI-targeted biopsy of different cores. Results:Of the 121 patients in this study, the biopsy results were negative for 43 patients (35.5%) and positive for 78 (64.5%). The detection rate of clinically significant PCa was 55.4% (67/121). The detection rate of the 6-core systematic biopsy combined with MRI-targeted biopsy was 62.0% (75/121) for PCa and 55.4% (67/121) for clinically significant PCa, which was of no difference compared with that for the 12-core systematic biopsy combined with MRI-targeted biopsy ( P>0.05), but the 6-core systematic biopsy combined with MRI-targeted biopsy avoided the overdiagnosis of 3 patients with Gleason score 3+ 3. The detection rate of PCa for MRI-targeted biopsy was 57.9% (70/121), including 42.1% (51/121) for the first core, 55.4% (67/121) for the first two cores, and 57.9% (70/121) for the first three cores. Compared with the single-core targeted biopsy for suspicious lesions, the first 2-core targeted biopsy ( OR=1.7, 95% CI 1.0-2.8) and 3-core targeted biopsy ( OR=1.9, 95% CI 1.1-3.1) can significantly increase the detection rate of PCa, while the fourth or fifth core of targeted biopsy can not increase the detection rate additionally (60%, 36/60). Conclusion:For patients with suspected PCa, the prostate biopsy strategy combing 6-core systematic and 3-core MRI-targeted biopsy performs no inferior than the current 12-core systematic biopsy combined with MRI-targeted biopsy.

Accumulating epidemiological evidence shows that handgrip strength provides predictive potential in physical, mental, and reproductive health status. However, the associations between handgrip strength and semen characteristics have not been explored. We recruited 1382 eligible men at the Hubei Province Human Sperm Bank (Wuhan, China) who had their handgrip strength measured at recruitment and provided 6458 repeated semen specimens within a 6-month period. Semen characteristics, including semen volume, sperm motility parameters (immotility, nonprogressive motility, and progressive motility), and sperm concentration, were assessed. Mixed-effect models and restricted cubic spline functions were applied to investigate the relationship of handgrip strength with repeated measurements of semen characteristics. After adjusting for confounding factors, the mixed-effect models revealed that handgrip strength was positively associated with semen volume, sperm concentration, progressive motility, total motility, and total count (all P for trend < 0.05). Compared to men in the lowest quartile, those in the highest quartile of handgrip strength had higher semen volume, sperm concentration, progressive motility, total motility, and total count, with measurements of 14.2% (95% confidence interval [CI]: 5.9%-23.2%), 19.5% (95% CI: 7.3%‒33.1%), 9.5% (95% CI: 3.4%‒15.9%), 8.8% (95% CI: 3.2%‒14.6%), and 36.4% (95% CI: 18.9%‒56.5%), respectively. These positive dose-response relationships were further confirmed in restricted cubic splines, where handgrip strength was modeled as a continuous variable. Handgrip strength, as an indicator of muscular function and strength, was positively associated with semen characteristics in a dose-dependent manner.

This study aimed to assess the role of prostate-specific antigen density (PSAD) and negative multiparametric magnetic resonance imaging (mpMRI) in predicting prostate cancer for biopsy-naïve men based on a large cohort of the Chinese population. From a prostate biopsy database between March 2017 and July 2021, we retrospectively identified 240 biopsy-naïve patients with negative prebiopsy mpMRI (Prostate Imaging Reporting and Data System version 2 [PI-RADS v2] score <3). Logistic regression analysis was performed to select the potential predictors for clinically significant prostate cancer (csPCa). Receiver operating characteristic (ROC) curve analysis and area under the ROC curve (AUC) were performed to assess the diagnostic accuracy. The negative predictive values of mpMRI in excluding any cancer and csPCa were 83.8% (201/240) and 90.8% (218/240), respectively. ROC curve analysis indicated that PSAD was the most promising predictor, with an AUC value of 0.786 (95% confidence interval [CI]: 0.699-0.874), and multiparametric logistic regression analysis confirmed that higher PSAD remained a significant marker for predicting csPCa (odds ratio [OR]: 10.99, 95% CI: 2.75-44.02, P < 0.001). Combining negative mpMRI and PSAD below 0.20 ng ml^-2 obviously increased the predictive value in excluding PCa (91.0%, 101/111) or csPCa (100.0%, 111/111). If a PSAD below 0.20 ng ml^-2 was set as the criterion to omit biopsy, nearly 46.3% of patients (463 per 1000) with negative mpMRI could safely avoid unnecessary biopsy, with approximately 4.2% of patients (42 per 1000) at risk of missed diagnosis of PCa and no patients with csPCa missed. A PI-RADS v2 score <3 and a PSAD <0.20 ng ml^-2 could be potential criteria for the Chinese population to omit prompt biopsy safely.
