Objective: To examine the associations between 24 hour movement behavior allocation patterns and physical fitness as well as serum high sensitivity C-reactive protein (hsCRP) levels among female college students, providing evidence for developing personalized health promotion strategies. Methods: In September 2025, 48 female college students aged 18-22 years were recruited from a comprehensive university from Shanghai. Continuous 24 hour movement behaviors were monitored using a triaxial accelerometer (ActiGraph GT3X+). Serum hsCRP levels were measured (≥1 000 ng/mL was log grade inflammation), and physical fitness indicators including upper limb muscle strength, vital capacity, and maximal oxygen consumption (VO 2max ) were assessed. Spearman rank correlation analysis was used to evaluate the correlation between variables. Compositional data analysis combined with multiple linear regression was employed to construct isotemporal substitution models, evaluating the effects of substituting 30 minutes of one behavior for another on hsCRP and VO 2max . Results: Female college students had the longest average daily sedentary behavior (SB) time (643.2±103.2)min, which was higher than sleep time (452.4±90.0)min, light physical activity (LPA) time (279.0±76.8)min and moderate to vigorous physical activity (MVPA) time (66.0±21.6)min. Correlation analysis revealed that vigorous physical activity (VPA) was positively correlated with hsCRP levels among female college students ( r=0.47, P <0.05). Substituting 30 minutes of MVPA with sleep, SB or LPA significantly reduced predicted hsCRP levels among female college students ( β = -0.90, -0.90, -0.73), replacing 30 minutes of sleep with MVPA significantly increased predicted VO 2max levels ( β =5.12) (all P <0.05). The low grade inflammation group exhibited longer durations of high intensity activity participation and higher mean values for height, body weight, and grip strength compared to the normal group ( t =2.17, 2.52, 2.21, all P <0.05). Within the normal inflammation group, MVPA was positively associated with VO 2max ( β =0.18), while sleep was negatively associated ( β =-0.07) (both P <0.05). In contrast, no statistically significant associations were observed between any activity behavior and VO 2max in the low grade inflammation group (all P >0.05). Conclusions MVPA exerts bidirectional effects on the health of female college students. While it enhances cardiorespiratory fitness, it may concurrently elevate chronic low grade inflammation levels. To maximize health benefits, intervention programs focused on increasing MVPA should also give full consideration to the importance of restorative sleep.

Objective:o evaluate the clinical efficacy of the induced membrane technique combined with an antibiotic-impregnated bone cement-coated plate fixation in the treatment of chronic osteomyelitis of the distal femur.Methods:A retrospective study was performed on patients diagnosed with chronic osteomyelitis of the distal femur, who received the induced membrane technique combined with an antibiotic-impregnated bone cement-coated plate fixation at Southwest Hospital from November 2016 to December 2022. All patients underwent a two-stage surgical protocol. Stage I involved thorough debridement, placement of antibiotic-impregnated bone cement spacers, and internal fixation with antibiotic-impregnated bone cement-coated plates. Stage II comprised internal fixation for the repair and reconstruction of bone defects. Intraoperatively, microbial culture, antibiotic susceptibility testing, and pathological examination were conducted on bone tissue lesion samples to guide targeted anti-infective therapy. Postoperatively, laboratory markers including C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), along with clinical manifestations (e.g., incision drainage, redness, fever, and pain), were monitored to exclude infection recurrence. Infection control was ultimately confirmed by intraoperative frozen section analysis during the second stage. Additionally, bone healing was evaluated via X-ray of the affected limb every month after the second-stage surgery, and lower limb function was assessed using the final knee range of motion (ROM) and the lower extremity function scale (LEFS).Results:A total of 104 patients met the inclusion criteria, including 70 males and 34 females, with a mean age of 35.2±12.13 years. Thirty-seven patients were diagnosed with chronic hematogenous osteomyelitis (CHO) and 67 with post-traumatic osteomyelitis (PTOM). The mean follow-up was 25.48±6.61 months (range, 12-38 months). After the first-stage surgery, infection recurred in 6 CHO and 15 PTOM patients, requiring repeated debridement. Two CHO patients experienced infection recurrence after second-stage reconstruction, which was successfully controlled with further staged treatment. Five PTOM patients developed nonunion after second-stage bone grafting but ultimately achieved bone union after revision surgery. At final follow-up, CRP levels were 4.45±4.23 mg/L (CHO) and 5.16±4.26 mg/L (PTOM), and ESR levels were 5.47±7.42 mm/h (CHO) and 8.51±8.72 mm/h (PTOM), all significantly lower than preoperative values (CRP: CHO 68.31±65.61, PTOM 42.71±80.46; ESR: CHO 52.18±34.29, PTOM 45.87±39.13; all P<0.05). All patients ultimately achieved bone union. One PTOM patient with a preoperative rupture of the knee extensor mechanism had limited improvement in ROM (15° preoperatively vs. 12° at 4-year follow-up). In the remaining patients, knee ROM at final follow-up was significantly improved (CHO: 101.38°±43.73°, PTOM: 94.28°±43.94°) compared with preoperative values (CHO: 57.17°± 4.53°, PTOM: 39.61°±52.61°; all P<0.05). The final LEFS scores were 72.18±9.51 (CHO) and 71.66±10.25 (PTOM). Conclusion:The findings of this study demonstrate that the combination of the "Chongqing Technique" and the "Membrane-Induced Technique" is effective in eradicating chronic osteomyelitis of the distal femur, promoting bone healing, and restoring satisfactory knee joint function.

Objective:To explore the evaluation and relationship of hepatitis B virus(HBV)surface antigen(HBsAg)in clinical laboratory in different detection systems,further scientifically and reasonably to explain the test results for serving clinical practices.Methods:During the period from June 2021 to July 2022,100 425 specimens of patients with screened,suspected and confirmed HBV infections were collected from the clinical departments(mainly infectious hepatology)of Nanyang Central Hospital.Detection methodology included quantitative(electrochemiluminescence and chemiluminescence),qualitative(gold standard),semi-quantita-tive(ELISA),and highly sensitive HBV-DNA(RT-PCR)methods,and then analyzed the strengths and weaknesses and closeness be-tween each methodology.The relationship between the two Roche HBsAg detection systems was analyzed by correlation analysis.The HBsAg efficacy analysis was validated using Cut/Off value setting and detection limit,which in turn analyzed the distribution of false-positive and false-negative reporting models.Results:Detection results for low-and medium-concentration HBsAg showed a correla-tion between the electrochemical luminescence semi-quantitative method and ELISA method.ELISA method still had advantages in terms of sensitivity and specificity when detecting HBsAg,and there were no significant differences compared to domestic and interna-tional HBsAg quantitative detection systems.Performance validation conducted in accordance with the CNAS-GL038 document showed that the minimum detection limit for HBsAg calculated using the ELISA method in this laboratory was 0.1 U/ml.When the ROC curve Cut/Off value was set to 0.105,the area under the curve was the largest(AUC=0.986).Based on Roche's semi-quantitative electroche-miluminescence detection and patient medical history,in the common reporting model for hepatitis B five-item detection using ELISA method,HBsAg false positives occurred most frequently when HBsAg was positive alone,and HBsAg occurred most frequently in the false positive range when the OD value was less than 0.5.In ELISA method for detecting HBsAg,as the OD value increased from 0.01 to 0.10,the number of false-negative results also increased.Roche Elecsys HBsAg Ⅱ Quant Ⅱ and Elecsys HBsAg Ⅱ testing systems exhibited good linearity under certain conditions,with a ratio of approximately 1/0.18.In Elecsys HBsAg Ⅱ Quant Ⅱ detection sys-tem,the test results of HBsAg samples diluted 400 times were highly consistent with the original test results with a coefficient of deter-mination R2=0.993 8.Conclusion:There was a certain relationship between various detection systems of HBsAg at a suitable concen-tration.The detection of HBsAg by ELISA can meet the needs of clinical detection.

Objective:To evaluate the effect of toric collamer lens (TICL) rotation on myopia combined with astigmatism correction after V4c TICL implantation using standardized vector analysis.Methods:An observational case series study was performed.A total of 152 patients (268 eyes) who underwent V4c TICL implantation for the correction of myopia and myopic astigmatism were enrolled at Henan Eye Hospital from January to December 2021.The preoperative spherical diopter, cylindrical diopter, and spherical equivalent (SE) were -15.00 to -3.25 D, -5.00 to -0.50 D, -16.50 to -3.88 D, respectively.Postoperative TICL vault and axis were measured by anterior segment optical coherence tomography, and postoperative TICL rotation was calculated.Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), spherical diopter, cylindrical diopter, SE, and target astigmatism vector were recorded before and 1 month after surgery.The effectiveness index, safety index, surgically induced astigmatism vector (SIA), margin of error (ME), absolute value of the difference vector |DV|, correction index (CI), and achievement index (IS) were calculated based on the subjective refraction results 1 month after surgery and the cylindrical axis of the V4c TICL.Vector analysis parameters was compared among patients with different preoperative astigmatism, intraoperative TICL fixation, postoperative TICL rotation, and postoperative vault.The correlation between postoperative TICL rotation and TICL fixed angle deviation, postoperative vault, visual acuity and refraction, and vector analysis parameters were evaluated.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]).Written informed consent was obtained from each subject.Results:At 1 month postoperatively, the mean safety and efficacy indices were 1.27 and 1.29, respectively.There was no statistically significant difference between the predicted SE of (-0.11±0.13)D and the postoperative SE of (-0.07±0.52)D ( t=-0.994, P=0.321).UCVA, BCVA and cylinder diopter in the operative eyes were all improved after surgery compared to before surgery and the differences were statistically significant ( t=17.854, 5.446, -25.634; all P<0.001).The rotation of V4c TICL was 0° to 25°, with a mean of (5.41±4.35)°, which was positively correlated with the V4c TICL fixed angle deviation ( rs=0.461, P<0.001), negatively correlated with postoperative cylindrical diopter and positively correlated with postoperative UCVA, |DV| and SIA ( r=-0.360, 0.191, 0.205, 0.142; all P<0.05).Vector analysis between groups showed that vault, SIA and |DV| were higher and CI and IS were lower in low astigmatism group than in high astigmatism group ( Z=-3.017, -13.569, -2.793, -2.761, -4.779; all P<0.05).V4c TICL rotation and |DV| were lower in low fixation angle difference group than in high fixation angle difference group ( Z=-7.865, -2.080; both P<0.05).Preoperative cylindrical diopter, intraoperative V4c TICL fixed angle deviation, SIA and |DV| were lower in low rotation group than in high rotation group ( Z=-2.104, -4.578, -2.456, -2.090; all P<0.05).There were no statistically significant differences in the TICL rotation or in each vector between patients with different vault after the surgery (all P>0.05). Conclusions:V4c TICL implantation can achieve good results for the correction of myopia and myopic astigmatism.There is a slight difference between the fixation axis and the target axis of V4c TICL, which affects the rotation of V4c TICL and |DV|.Postoperative V4c TICL rotation is related to TICL fixed angle deviation, postoperative UCVA, SIA, |DV| and postoperative cylindrical diopter.Postoperative vault has no significant effect on TICL rotation and differences in each vector.

OBJECTIVE: To observe the effects of electroacupuncture (EA) with different frequencies on spermatogenic function, testicular morphology and oxidative stress in oligoasthenospermia (OAT) rats, and to explore the mechanism and the optimal parameters of EA for OAT. METHODS: Sixty SPF-grade male SD rats were randomly divided into a solvent control group, a model group, a 2 Hz EA group, a 100 Hz EA group and a 2 Hz/100 Hz EA group, with 12 rats in each group. Except for the solvent control group, the other 4 groups were administered ornidazole suspension (800 mg·kg^-1·d^-1) by gavage for 28 d to establish the OAT model. Starting from the 1st of modeling, EA was applied at "Guanyuan" (CV4), "Qihai" (CV6) and bilateral "Sanyinjiao" (SP6) and "Zusanli" (ST36) in the 3 EA groups, continuous wave of 2 Hz, continuous wave of 100 Hz, and disperse-dense wave of 2 Hz/100 Hz were used in the 2 Hz EA group, the 100 Hz EA group, and the 2 Hz/100 Hz EA group, respectively, with current intensity of 1-3 mA, 30 min a time, once every other day, for 28 consecutive days. After intervention, the testicular index was calculated, epididymal sperm quality was assessed, and the fertility ability was observed; morphology of testicular tissue was observed by HE staining, and the Johnson score was calculated; the positive expression of reactive oxygen species (ROS) in testicular tissue was detected by immunofluorescence; the activity of superoxide dismutase (SOD) and catalase (CAT), as well as the level of malondialdehyde (MDA) in testicular tissue were measured by ELISA; the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in testicular tissue was detected by Western blot. RESULTS: Compared with the solvent control group, in the model group, the testicular index, sperm concentration, sperm motility and the number of offspring were decreased (P<0.01), the seminiferous tubules atrophied and the Johnson score decreased (P<0.01); the activity of SOD and CAT, as well as the protein expression of Nrf2 and HO-1 in testicular tissue were decreased (P<0.01); the sperm deformity rate, the positive expression of ROS and the MDA level in testicular tissue were increased (P<0.01). Compared with the model group, in the 2 Hz EA group, the 100 Hz EA group and the 2 Hz/100 Hz EA group, the testicular index, sperm concentration, sperm motility and the number of offspring were increased (P<0.05, P<0.01), the pathological morphology of testicular tissue improved and the Johnson scores increased (P<0.01); the activity of SOD and CAT, as well as the protein expression of Nrf2 and HO-1 in testicular tissue were increased (P<0.05, P<0.01); the sperm deformity rate, the positive expression of ROS and the MDA level in testicular tissue were decreased (P<0.05, P<0.01). Compared with the 2 Hz EA group, in the 2 Hz/100 Hz EA group, the testicular index, sperm concentration, sperm motility, as well as the CAT activity and HO-1 protein expression in testicular tissue were increased (P<0.01, P<0.05); the positive expression of ROS was decreased (P<0.01). Compared with the 100 Hz EA group, in the 2 Hz/100 Hz EA group, the testicular index was increased (P<0.01), the positive expression of ROS in testicular tissue was decreased (P<0.01). CONCLUSION EA with 2 Hz continuous wave, 100 Hz continuous wave, and 2 Hz/100 Hz disperse-dense wave can all improve the spermatogenic arrest and reduce the level of oxidative stress in testicular tissue in OAT rats, the mechanism may be related to up-regulating the protein expression of Nrf2 and HO-1 and improving oxidative stress. EA with disperse-dense wave of 2 Hz/100 Hz shows the optimal effect.
