Shengma Gegentang is one of the classic formulas in the Catalogue of Ancient Classic Prescriptions （Second Batch）. This study reviewed ancient and modern literature and used literature tracing and bibliometric methods to analyze the historical evolution， efficacy， indications， dosage decoctions， and modern clinical disease spectrum of Shengma Gegentang. The results indicated that the earliest record of Shengma Gegentang can be found in the Taiping Huimin Heji Jufang of the Song dynasty， but its origin can be traced back to the Shaoyao Siwu Jiejitang in the Beiji Qianjin Yaofang of the Tang dynasty. The composition dosage of Shengma Gegentang is 413 g of Cimicifugae Rhizoma， 619.5 g of Puerariae Lobatae Radix， 413 g of Paeoniae Radix Alba， and 413 g of Glycyrrhizae Radix et Rhizoma， which are ground into coarse powder. Each dose is 12.39 g， and the amount of water added is 300 mL. 100 mL of solution is decocted and taken at the right time. The four drugs in the formula play the role of relieving exterior syndrome， penetrating pathogenic factors， and detoxicating together. Its indications are widely involved in internal medicine， pediatrics， surgery， ophthalmology and otorhinolaryngology， obstetrics and gynecology， sexually transmitted diseases， and other diseases， such as measles， sores， acne， spots， surgical gangrene， red eyes， toothache， chancre， and fetal poison. The epidemic diseases treated by Shengma Gegentang are complicated， including rash， pox， macula， numbness， summer diarrhea， dysentery， sha disease， febrile symptoms， spring warmth， winter warmth， and cold pestilence. At the same time， it is a plague prevention formula. Although Shengma Gegentang has a wide range of indications， it cannot be separated from the pathogenic mechanism of evil Qi blocking the muscle surface and heat in the lungs and stomach. The modern clinical disease spectrum of Shengma Gegentang involves the ophthalmology and otorhinolaryngology system， nervous system， pediatric-related diseases and syndromes， skin system， hepatobiliary system， and digestive system. It plays a key role in the treatment of epidemic diseases such as measles， chronic hepatitis B， dysentery， and tetanus.

ObjectiveTo understand the uncorrected visual acuity, spherical equivalent and hyperopia reserve of 6‒8-year-old primary school students in Jing’an District of Shanghai, and to provide a scientific basis for further myopia prevention and control. MethodsA total of 619 children aged between 6‒8 years old from three primary schools in Jing’an District were selected by cluster sampling method for uncorrected eye visual acuity examination and diopter examination after cycloplegia (mydriasis). ResultsThe mean uncorrected visual acuity of the619 students aged 6‒8 years old was (4.9±0.2), and the mean spherical equivalent was (0.84±1.11) D. The difference in uncorrected visual acuity was not statistically significant as the age increased (F=0.057, P=0.812), but the spherical equivalent decreased with the increase of age, showing a statistically significant difference (F=26.533, P<0.001). There was no statistically significant difference in uncorrected visual acuity(t=-1.614, P=0.107) and spherical equivalent (t=-1.675, P=0.094) between students of different genders. Finally, among the 619 students, 59.80% of them had abnormal uncorrected visual acuity, 34.90% had insufficient hyperopia reserve, and only 5.30% had sufficient hyperopia reserve. Besides, the proportion of abnormal uncorrected visual acuity in 7-year-old students was 67.50%, higher than that of students with other ages, and the difference was statistically significant (χ²_trend=29.729, P<0.001). While the difference in abnormal uncorrected visual acuity between students of different genders was not statistically significant (χ²=0.068, P=0.967). ConclusionThe deficiency of hyperopia reserve in 6‒8-year-old students in Jing’an District of Shanghai is serious. Attention should be paid to the visual acuity of school-aged children in lower grades, and intervention measures should be actively carried out to slow down the progression of myopia.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

Objective:To evaluate the role of lactate dehydrogenase in diabetic neuropathic pain (DNP) and the relationship with peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) in mice.Methods:SPF-grade healthy male C57BL/6J mice, aged 6-8 weeks, weighing 18-22 g, were used to establish diabetes mellitus model by intraperitoneal injection of streptozotocin (STZ) 120 mg/kg. Twenty-four mice with diabetes mellitus were divided into 2 groups ( n=12 each) using a random number table method: DNP group and DNP + oxamate group (OXA group). Another 12 SPF-grade healthy male C57BL/6J mice were selected as control group (C group). In OXA group, oxamate 750 mg/kg was intraperitoneally injected once a day for 28 consecutive days. The equal volume of normal saline was given instead in C group and DNP group. The mechanical paw withdrawal threshold (MWT), blood glucose and body weight were measured at 3 days before STZ injection and at 1, 2, 3 and 4 weeks after STZ injection (T 0-4). After the last behavioural test was completed, blood samples were collected from the posterior orbits of anesthetized mice for determination of serum lactate concentrations. The animals were then sacrificed and the tissues from the prefrontal cortex of the brain were taken for determination of lactate content, mitochondrial membrane potential (by the JC-1), content of reactive oxygen species (ROS) (using dihydroethidium probes), and level of histone lactylation and expression of PGC-1α (by Western blot). Results:Compared with C group, the MWT was significantly decreased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were increased, the mitochondrial membrane potential was decreased, and the expression of PGC-1α was down-regulated in DNP and OXA groups ( P<0.05). Compared with DNP group, no significant change was found in blood glucose and body weight ( P>0.05), the MWT was significantly increased at T 2-4, the serum lactate concentrations, contents of lactate and ROS and level of histone lactylation were decreased, the mitochondrial membrane potential was increased, and the expression of PGC-1α was up-regulated in OXA group ( P<0.05). Conclusions:Lactate dehydrogenase promotes the development of DNP, and the mechanism is related to promotion of increase in histone lactfication and down-regulation of PGC-1α expression in the prefrontal cortex of mice.

Objective To explore the safety and effectiveness of transvaginal ischia spinous fascia fixation for pelvic organ prolapse.Methods The retrospective analysis of 124 patients who underwent surgical treatment for stage Ⅲ-Ⅳ pelvic organ prolapse was conducted.Among them, 53 cases of transvaginal ischia spinous fascia fixation (IS-FF) were performed as a study group (ISFF group) while 71 cases of transvaginal sacrospinous ligament fixation (SSLF) were performed as a control group (SSLF group) .The operation time, postoperative hospitalization days, preoperative and postoperative hemoglobin values, indwelling urinary catheter time, postoperative pain scores, and the occurrence of complications were compared between the two groups, and the efficacy of the operation was objec-tively evaluated by using the staging method of pelvic organ prolapse (POP-Q) .Also the scores of the pelvic floor impact questionnaire-7 (PFIQ-7) , the pelvic floor dysfunction questionnaire-20 (PFDI-20) , and the questionnaire of quality of life12 (PISQ-12) were used to evaluate the patients' postoperative quality of life.Results The oper-ation time and postoperative hospitalization days of patients in the ISFF group were less than those in the SSLF group , and the differences were statistically significant (P<0.05) .The preoperative and postoperative hemoglobin values, retention time of urinary catheter, postoperative pain scores, and hospitalization costs of patients in the two groups were compared, and the differences were not statistically significant.At the 3-month postoperative outpatient follow-up, the objective success rate was 100％ in two groups.The median follow-up time of patients in both groups was 24 months (12-41 months) , and there were 2 cases of recurrence in the ISFF group, with a recurrence rate of 3.77％ and a subjective success rate of 96.23％.While there were 3 cases of recurrence in the SSLF group and 2 cases of loss of visit, with a recurrence rate of 4.34％ and a subjective success rate of 95.65％.1 patient in the SSLF group presented with a pelvic hematoma with a diameter of about 5 cm after surgery.The hematoma disap-peared after hemostasis and other symptomatic treatment.There was no organ injury or blood transfusion in both groups.Conclusion Transvaginal ischia spinous fascia fixation is a safe and effective treatment for pelvic organ prolapse, and it has the advantages of short operation time, fast postoperative recovery, fewer complications, and improvement of patients' quality of life.

Objective To investigate the relationships of pre-radiotherapy body weight,gender,age,EBVDNA,hemoglobin,plasma albumin,and induction chemotherapy regimen with the changes of target area and lymph node volume in adaptive radiotherapy,so as to provide a reference for the timing and population selection of adaptive radiotherapy.Methods A retrospective analysis was conducted on 34 patients who received the first course of radiotherapy at Sun Yat-sen University Cancer Center from January 2022 to November 2022.All patients underwent CT scans again after 20 sessions of radiotherapy for developing the secondary radiotherapy plans.The body weight,gender,age,tumor stage,hemoglobin,plasma albumin,induction chemotherapy regimen,and EBVDNA were collected.Results The tumor volume reduction in the primary focus was more evident in patients with pre-treatment plasma albumin≥40 g/L than in those with pre-treatment plasma albumin<40 g/L(t=3.971,P=0.001),and in patients with pretreatment EBVDNA≤4000 copies/mL than in those with pretreatment EBVDNA>4000 copies/mL(t=4.080,P=0.001).Pearson analysis showed that GTVnx volume difference was positively correlated with pre-radiotherapy GTVnx volume(r=0.444,P=0.009),right parotid gland volume difference(r=0.737,P<0.001),left parotid gland volume difference(r=0.435,P=0.010),and hemoglobin(r=0.722,P<0.001).Conclusion The reduction in tumor volume during radiotherapy is more pronounced in nasopharyngeal cancer patients with normal plasma albumin level and those with pretreatment EBVDNA≤4000 copies/mL.The pre-radiotherapy treatment volume of primary focus,parotid gland volume change before and after radiotherapy,and pre-radiotherapy EBVDNA,hemoglobin and plasma albumin levels can be used to predict the degree of tumor volume shrinkage during radiotherapy,providing a reference for the selection of the timing of adaptive radiotherapy for nasopharyngeal carcinoma.

Objective:To compare the efficacy of unilateral percutaneous kyphoplasty (PKP) and unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve in the treatment of lumbar osteoporotic vertebral compression fracture (OVCF) in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 161 aged patients with newly developed lumbar OVCF, admitted to Xi′an Central Hospital Affiliated to Xi′an Jiaotong University School of Medicine from January 2019 to January 2023, including 58 males and 103 females, aged 61-88 [(72.9±6.3)years]. All the patients were diagnosed with type II compression fracture based on acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). Seventy-eight patients underwent unilateral PKP (PKP group), while the other 83 patients underwent unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve (PKP+contralateral block group). The operation time, intraoperative blood loss, and length of hospital stay were recorded. Beck index of the injured vertebra, Cobb angle of lumbar lordosis, Roland-Morris disability (RMD) score, visual analogue scale (VAS), and Oswestry disability index (ODI) were evaluated before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up. The incidence of complications such as cement leakage was recorded as well.Results:All the patients were followed up for 6-8 months [(6.7±0.6)months]. There were no significant differences between the two groups in the operation time, intraoperative blood loss, or length of hospital stay ( P>0.05). The Beck index of the injured vertebra and Cobb angle of lumbar lordosis were not significantly different between the two groups before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up ( P>0.05). The RMD score of the injured vertebra, VAS score, and ODI were not significantly different between the two groups before operation ( P>0.05). At 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up, the RMD scores in the PKP+contralateral block group were (11.23±1.05)points, (10.90±1.11)points, (10.10±1.06)points, (9.94±1.06)points, and (9.60±0.83)points respectively, which were all lower than (17.55±0.71)points, (15.78±0.86)points, (13.42±0.92)points, (10.67±0.78)points, and (9.78±0.72)points in the PKP group ( P<0.05 or 0.01); the VAS scores in the PKP+contralateral block group were (3.02±0.60)points, (2.96±0.55)points, (2.92±0.57)points, (2.88±0.61)points, and (2.70±0.51)points respectively, which were all lower than (3.60±0.57)points, (3.47±0.55)points, (3.32±0.46)points, (2.99±0.47)points, and (2.77±0.42)points in the PKP group ( P<0.05 or 0.01); the ODI values in the PKP+contralateral block group were 14.43±1.29, 14.54±1.24, 14.63±1.32, 14.37±1.31, and 13.42±1.45 respectively, which were all lower than 16.72±1.64, 16.09±1.49, 14.82±1.53, 14.74±1.46, and 13.69±1.75 in the PKP group ( P<0.05 or 0.01). The bone cement leakage rate was 12.0% (10/83) in the PKP+contralateral block group, similar to 11.5% (9/78) in the PKP group ( P>0.05). No other complications such as neurovascular injury, pulmonary embolism or adjacent vertebral fracture were found in either groups. Conclusion:In the treatment of lumbar OVCF in the elderly, unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve is similar to unilateral PKP in terms of the operation time, intraoperative blood loss, length of hospital stay, effectiveness of reduction, and incidence of complications, but it can achieve better pain relief and more satisfactory functional recovery.

Background::The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.Methods::A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific mortality.Results::During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality ( P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger people. Conclusions::People with very low LDL-C had a higher risk of all-cause, CVD, and HS mortality; those with very high LDL-C had a higher risk of all-cause, CVD, and CHD mortality. On the basis of our findings, comprehensive health assessment is needed to evaluate cardiovascular risk and implement appropriate lipid-lowering therapy for people with very low LDL-C.

Objective:To evaluate the role of lactate-induced mitochondrial division of spinal cord neurons in diabetic neuropathic pain (DNP) in mice.Methods:Thirty-six SPF-grade healthy adult male C57BL/6 mice, aged 2 months, weighing 20-25 g, were divided into 3 groups ( n=12 each) using a random number table method: control group (CON group), DNP group, and DNP+ sodium oxalate group (OXA group). The diabetic model was established by intraperitoneal injection of streptozotocin 130 mg/kg. After the diabetic model was successfully established, sodium oxalate 750 mg/kg was intraperitoneally injected once a day for 4 consecutive weeks to inhibit lactate production in OXA group, while the equal volume of normal saline was given instead at the same time in C group and DNP group. The mechanical paw withdrawal threshold (MWT) of the left hindpaw was measured before developing the model and at 1, 2, 3 and 4 weeks after developing the model. After completing the last behavioral testing, the spinal cord tissue of the lumbar segment (L 4-6) was taken for determination of the levels of lactate in serum and spinal cord tissues (by the colorimetric method), expression of the mitochondrial membrane potential, reactive oxygen species (ROS) content (using JC-1 or DHE probes), expression of mitochondrial dynamin-related protein 1 (Drp1) and mitochondrial protein mitofusin 2 (Mfn2) (by Western blot), and co-expression of Drp1 and neuronal neuronal marker neuronal nuclear protein (NeuN) (by immunofluorescence double labeling) and for examination of the structure and the number of mitochondria (with a transmission electron microscope). Results:Compared with C group, the MWT was significantly decreased after developing the model, the levels of lactate in serum and spinal cord tissues and ROS content in the spinal cord were increased, the mitochondrial membrane potential was decreased, the Drp1 expression was up-regulated, the Mfn2 expression was down-regulated, the number of mitochondria was increased, the area was reduced ( P<0.05), and the co-expression of Drp 1 and NeuN was increased in DNP group and OXA group. Compared with DNP group, the MWT was significantly increased after developing the model, the levels of lactate in serum and spinal cord tissues and ROS content in the spinal cord were decreased, the mitochondrial membrane potential was increased, the Drp1 expression was down-regulated, the Mfn2 expression was up-regulated, the number of mitochondria was decreased, the area was increased ( P<0.05), and the co-expression of Drp 1 and NeuN was decreased in OXA group. Conclusions:Lactate-induced excessive mitochondrial division of spinal cord neurons can lead to mitochondrial dysfunction, which may be involved in the maintenance mechanism of DNP in mice.
