ObjectiveTo observe the clinical efficacy of tonifying kidney and replenishing essence on asthenozoospermia patients with the syndrome of kidney essence deficiency and the effects of this method on the adenosine 5′-monophosphate-activated protein kinase （AMPK）/mammalian target of rapamycin complex 1 （mTORC1） signaling pathway. MethodsSeventy-two eligible asthenozoospermia patients with the syndrome of kidney essence deficiency treated in the Affiliated Hospital of Chengdu University of Traditional Chinese Medicine from February 2023 to January 2024 were selected and randomly assigned into an observation group and a control group， with 36 patients in each group. The observation group received oral administration of Guilu Tianjing capsules， while the control group received oral administration of L-carnitine oral solution. The treatment course lasted for 4 weeks in both groups. The observed indicators included sperm progressive motility rate （PR）， total sperm motility （PR+NP）， percentage of normal mitochondrial membrane potential （MMP）， and traditional Chinese medicine （TCM） symptom scores before and after treatment in both groups. A three-month follow-up was instituted to record the conception status of the patients’ spouses. Additionally， eight patients were randomly selected from the eligible patients in the observation group， and four healthy males with normal semen routine examination results were included as the control group for the determination of protein expression. Western blotting was conducted to assess the expression of AMPK， phosphorylated （p）-AMPK， regulatory-associated protein of mTOR （RAPTOR） and p-RAPTOR， and PTEN-induced putative kinase 1 （PINK1） in sperms from the observation group before and after treatment， as well as in the sperms of the control group. ResultsThe pregnancy rate of spouses in the observation group was 9.09% （3/33）， which was higher than that （3.33%， 1/30） in the control group. The total response rate was 84.8% （28/33） in the observation group and 66.7% （20/30） in the control group， with no statistically significant difference. After treatment， both groups were improved considering PR， PR+NP， MMP， and TCM symptom scores （P<0.01）. Moreover， the observation group exhibited more pronounced decreases in TCM symptom scores than the control group （P<0.05）， while the changes in PR， PR+NP， and MMP showed no statistical significance between groups. Compared with the control group， the asthenozoospermia group exhibited upregulations in phosphorylation levels of AMPK and RAPTOR and protein level of PINK （P<0.01）. The administration of Guilu Tianjing Capsules led to downregulations in the phosphorylation levels of AMPK and RAPTOR and protein level of PINK1 （P<0.01）. However， the protein levels of AMPK and RAPTOR demonstrated no significant difference between before and after treatment. During the study period， neither group of patients exhibited any notable adverse reactions. ConclusionGuilu Tianjing capsules can enhance the sperm motility and percentage of normal mitochondrial membrane potential in asthenozoospermia patients with the syndrome of kidney essence deficiency by downregulating the AMPK/mTORC1 signaling pathway， lowering the protein level of PINK1， and inhibiting excessive activation of mitophagy.

OBJECTIVE To prepare reactive oxygen species （ROS）-responsive methotrexate （MTX）-modified paclitaxel （PTX）/icariin （ICA） micelles （MTX-oxi-Ms@PTX/ICA）， and perform technology optimization and in vitro anti-tumor effect evaluation. METHODS Synergistic toxicity concentration range of PTX and ICA was screened by synergistic toxicity test. The micelles were prepared by thin film hydration method， and their technology was optimized by response surface methodology. The fundamental characteristics of the micelles prepared by the optimal technology were evaluated. The micelles’ cytotoxicity， targeting ability to renal carcinoma RENCA cells of mice， and their inhibitory effects on invasion and migration were assessed. RESULTS Results of synergistic toxicity experiments demonstrated that the strongest synergistic effect occurred when PTX concentrations ranged from 2.5 to 10 μmol/L and ICA concentrations ranged from 5 to 15 μmol/L. The optimal technology of MTX-oxi-Ms@PTX/ ICA was determined to include 80 mg Soluplus®， Soluplus® and TPGS1000 mass ratio of 4∶1 （mg/mg）， 2 mg DSPE-PEG2000-TK- PEG5000， 2 mg DSPE-PEG2000-MTX， 1 mg PTX， and 1.5 mg ICA， with a hydration temperature of 35 ℃ and a formulation volume of 5 mL. Under the optimal conditions， average encapsulation efficiency of PTX and ICA in 3 batches of MTX-oxi- Ms@PTX/ICA reached 92.75%， the critical micelle concentration （CMC） was 0.007 9 mg/mL， the particle size was （62.09±1.68） nm， the polydispersity index （PDI） was 0.046±0.032， and the Zeta potential was （－2.47±0.15） mV. Within 30 days of placement， there was no significant change E-mail：yingqiang_1126@163.com in particle size and polydispersity index of micelle. In vitro release experiments showed that MTX-oxi-Ms@PTX/ICA released drugs more rapidly in oxidative environments. The half maximal inhibitory concentration of MTX-oxi-Ms@PTX/ICA against RENCA cells was （5.170±0.036） μmol/L. In vitro cellular uptake experiments indicated that compared with unmodified micelles， MTX modified micelles had stronger targeting effects on cancer cells， and also significantly enhanced the inhibitory ability of invasion and migration of RENCA cells （P＜0.05）. CONCLUSIONS MTX-oxi-Ms@PTX/ICA micelles are successfully prepared， which exhibit high encapsulation efficiency， low critical micelle concentration， and good stability. These micelles demonstrate significant cytotoxicity against RENCA cells and effectively inhibit cancer cell invasion and migration.

Objective: This study aimed to elucidate the hand function recovery capacity of degenerative cervical myelopathy (DCM) patients with different severities of hand dexterity impairment. Methods: Hand functional outcome measures such as the 10-second grip and release (10s-G&R) test, modified Japanese Orthopaedic Association (mJOA) upper extremity score and Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) upper extremity function were collected before surgery and at the 1-year follow-up. A total of 102 DCM patients were categorized into mild, moderate and severe group based on the preoperative 10s-G&R test result. Hand functional parameters were compared across the 3 groups. Multivariate linear regression was conducted to explore predictive factors. Receiver operating characteristic curve analysis was performed to assess the predictive efficacy of the preoperative 10s-G&R test and establish the cutoff value for incomplete recovery of hand dexterity. Results: At the 1-year follow-up, significant improvements were observed in all hand functional parameters across all 3 groups. However, the incomplete recovery rates of the mild, moderate, severe groups were 26.67%, 46.88%, and 57.50%, respectively (p < 0.05). Multivariate regression revealed that preoperative 10s-G&R test result, age, Hoffmann sign, duration of symptom, and mJOA Upper score serve as significant predictors for postoperative 10s-G&R test outcomes. Patients with a preoperative 10s-G&R test < 15 cycles have a 1.9 times higher risk of incomplete recovery of hand function (p = 0.005). Conclusion Most patients, regardless of their preoperative hand function, exhibit potential for improvement in hand dexterity. However, worse initial hand dexterity correlates with poorer outcomes. Surgical treatment is recommended before the 10s-G&R test drops below 15 cycles.

AIM: To compare the efficacy, safety, and complications of 27G and 25G vitrectomy in the treatment of rhegmatogenous retinal detachment(RRD)involving the macular area.METHODS:This retrospective study analyzed 60 patients(60 eyes)initially diagnosed with RRD involving the macular area and undergoing 25G or 27G vitrectomy combined with retinal reattachment at our hospital from January 2021 to December 2023. Patients were divided into 25G group(30 eyes)and 27G group(30 eyes). Best corrected visual acuity(BCVA), intraocular pressure(IOP), surgical duration, retinal reattachment rate and complications of both groups of patients were compared before and after surgery.RESULTS: The mean surgical time in the 27G group was slightly longer than in the 25G group(40.20±7.52 vs 36.97±7.47 min). Incision leakage occurred in 7 eyes(23%)in the 25G group versus 1 eye(3%)in the 27G group, though the difference was not statistically significant between two groups(P>0.05). At 6 mo postoperatively, BCVA(LogMAR)improved significantly in both groups(27G: 0.37±0.19 vs preoperative 0.98±0.32; 25G: 0.40±0.17 vs preoperative 0.84±0.33; all P<0.05), with no statistical difference in BCVA(P>0.05). At 1 d postoperatively, the 25G group had lower mean IOP(12.29±2.86 mmHg)compared to the 27G group(15.87±3.70 mmHg; P<0.001), but no differences were observed at 1 wk or 1 mo postoperatively(all P>0.05). Retinal reattachment rates and complications(intra- or postoperative)showed no significant intergroup differences(all P>0.05).CONCLUSION: Both 25G and 27G vitrectomy are safe and effective in treating rhegmatogenous retinal detachment. However, the 27G vitrectomy offers advantages such as small incisions, better self-sealing properties, and more stable IOP.

It is composed of Stephaniae Tetrandrae Radix， Astragali Radix， Cinnamomi Ramulus， Poria， and Glycyrrhizae Radix et Rhizoma， with the effects of reinforcing Qi and invigorating spleen， warming Yang and promoting urination. By a review of ancient medical books， this paper summarizes the composition， original plants， processing， dosage， decocting methods， indications and other key information of Fangji Fulingtang， aiming to provide a literature basis for the research， development， and clinical application of preparations based on this formula. Synonyms of Fangji Fulingtang exist in ancient medical books， while the formula composition in the Synopsis of the Golden Chamber is more widespread and far-reaching. In this formula， Stephaniae Tetrandrae Radix， Astragali Radix， Cinnamomi Ramulus， Poria， and Glycyrrhizae Radix et Rhizoma are the dried root of Stephania tetrandra， the dried root of Astragalus embranaceus var. mongholicus， the dried shoot of Cinnamomum cassia， the dried sclerotium of Poria cocos， and the dried root and rhizome of Glycyrrhiza uralensis， respectively. Fangji Fulingtang is mainly produced into powder， with the dosage and decocting method used in the past dynasties basically following the original formula. Each bag is composed of Stephaniae Tetrandrae Radix 13.80 g， Astragali Radix 13.80 g， Cinnamomi Ramulus 13.80 g， Poria 27.60 g， and Glycyrrhizae Radix et Rhizoma 9.20 g. The raw materials are purified， decocted in water from 1 200 mL to 400 mL， and the decoction should be taken warm， 3 times a day. Fangji Fulingtang was originally designed for treating skin edema， and then it was used to treat impediment in the Qing dynasty. In modern times， it is mostly used to treat musculoskeletal and connective tissue diseases and circulatory system diseases， demonstrating definite effects on various types of edema and heart failure. This paper clarifies the inheritance of Fangji Fulingtang and reveals its key information （attached to the end of this paper）， aiming to provide a theoretical basis for the development of preparations based on this formula.

[Objective] To explore quality issues and quality management measures in alanine aminotransferase (ALT) testing, aiming to improve consistency and accuracy of ALT test results by analyzing the outcomes from different pre-donation screening methods and different sample sources. [Methods] Data were collected from 58 blood collection and supply institutions across China. ALT test results from donor samples analyzed by dry chemistry analyzers, semi-automatic biochemical analyzers, and automatic biochemical analyzers were compared, focusing on the influence of venous versus capillary blood samples on testing accuracy. By comparing results from pre-donation screening with laboratory testing, the current state of quality management for different methods and sample types was assessed. Differences in ALT unqualified rates between laboratories were analyzed, and quality improvement strategies were proposed accordingly. [Results] No significant differences were found in laboratory ALT unqualified rates between venous and capillary blood samples during pre-donation screening across different analytical methods (P>0.05). However, laboratory ALT unqualified rates were consistently lower for venous blood compared to capillary blood, regardless of the testing method used (P<0.05). Notable differences in quality control were observed among various blood collection and supply institutions (P<0.05). [Conclusion] Minimal differences were observed between pre-donation ALT screening results obtained by the three analytical methods and laboratory test outcomes; thus, blood stations can select an appropriate testing method according to their specific conditions. Pre-donation screening using venous blood samples demonstrated superior reliability in quality control compared to capillary blood samples. Significant variations in ALT unqualified rates among blood stations suggest that blood collection and supply institutions should emphasize quality management at both the pre-donation screening and laboratory testing stages. Measures such as optimized standardized operating procedures, regular equipment calibration and maintenance, proficiency testing, internal quality control, inter-system comparisons, and enhanced personnel training and evaluation should be implemented to ensure consistent and stable screening results, thereby reducing ALT unqualified rates.
