Objective: To compare the effects of 12 week Tai Chi combined with inspiratory muscle resistance training on cardiopulmonary function among male college students in health care classes, so as to provide a reference for improving the cardiopulmonary function of the students. Methods: From March to May 2025, 72 male students from the physical education health care classes at North University of China were selected and randomly divided into the control group ( n =25), the Tai Chi group ( n = 24), and the Tai Chi combined with inspiratory muscle resistance training group (combined group, n =23) by random number table method. The control group maintained normal living habits, the Tai Chi group underwent 12 weeks of Tai Chi exercise (three sessions per week, 90 minutes per session), and the combined group received 12 weeks of Tai Chi training (three sessions per week, 60 minutes per session) combined with 30 minutes of inspiratory muscle resistance training. Cardiovascular function[heart rate(HR), stroke volume(SV), cardiac output(CO), mean systolic pressure(MSP), mean diastolic pressure(MDP), vascular elastic dilatation coefficient (VDC), total peripheral resistance (TPR), viscosity (V)], pulmonary function [vital capacity (VC), forced vital capacity (FVC), maximum minute ventilation volume (MVV), forced expiratory volume in one second (FEV1), FEV1/FVC] and heart rate variability (HRV) [HR, standard deviation of the normal to normal intervals (SDNN), root mean square successive difference (RMSSD), low frequency (LF), high frequency (HF), LF/HF] of the three groups of subjects were tested before and after the experiment, the data were analyzed using analysis of covariance. Results: There were no statistically significant differences in any indicators among the three groups before the intervention ( F =0.00-2.49, all P >0.05). After the intervention, except FEV1/FVC, MDP and V, there were statistically significant differences of pulmonary function, cardiovascular function and HRV indicators among the three groups ( F =4.38-62.93, all P <0.05). Compared with the control group [(VC ( 3.28± 0.30)L, FVC (3.20±0.29)L, MVV (107.01±9.55)L, SV (65.68±2.34)mL, CO (5.36±0.18)L/min, VDC (0.40±0.03), step index (50.64±3.11), MSP (133.17±6.47)mmHg, TPR (1 281.34±100.78)dyn ·s ·cm -5 ], the VC [(3.43±0.24, 3.69±0.21)L], FVC [(3.34±0.16, 3.46±0.20)L], MVV [(112.54±8.95, 117.11±6.37)L], SV [(71.75±4.20, 75.39±3.71)L/time], CO[( 5.53± 0.14, 5.58±0.15)L/min], VDC (0.43±0.03, 0.44±0.02) and step index (53.38±5.77, 56.17±4.91) in the Tai Chi group and the combined group significantly increased, while the MSP [(120.17±6.42, 118.04±12.99)mmHg] and TPR [( 1 227.01 ±107.25, 1 217.69±64.93)dyn ·s ·cm -5 ] significantly decreased (all P <0.05). The HRV showed improvement. Moreover, compared with the Tai Chi group, VC, FVC, MVV, FEV1[(2.99±0.14，3.05±0.15)L], SV, step index, RMSSD[( 45.41± 9.59，52.82±7.67)ms] and HF [(2.74±0.13，2.87±0.16)ms 2] increased, while HR [(77.17±6.01, 73.83± 3.71)beats/min ] decreased in the combined group (all P < 0.05 ). Conclusion Twelve weeks of Tai Chi exercise and Tai Chi combined with inspiratory muscle resistance training can improve the cardiopulmonary function of male college students in health care classes, and the effect of the combined training is superior to that of Tai Chi training alone.

Objective: To provide the mechanism-based pharmacotherapy of the Huatan Qushi formula (HTQS formula), for the health management and treatment of non-alcoholic fatty liver disease (NAFLD). Methods: A rat model of NAFLD was employed to examine the efficacy and safety of the HTQS formula. In vivo active components and potential mechanisms of the HTQS formula were identified using UPLC‒MS/MS combined with network pharmacology. The influence of the HTQS formula on the dominating proteins in PI3K/Akt pathway was validated in vivo using western blot. Finally, 16S rRNA sequencing of the gut microbiome was conducted followed by targeted metabolomics detecting fecal short-chain fatty acids (SCFAs) and bile acids to determine the impact of the HTQS formula on gut microbiota. Results: The HTQS formula reduced weight gain and hepatic steatosis in NAFLD rats and decreased serum total cholesterol (TC), triglycerides, blood glucose, and insulin resistance (IR) without causing liver or kidney injury. We detected 28 components using UPLC‒MS/MS and identified 439 shared targets between NAFLD and the HTQS formula. Primarily, we focused on the PI3K/Akt signaling pathway based on protein‒protein interaction network analysis. We validated that the HTQS formula inhibited liver steatosis and inflammation by increasing the phosphorylation levels of PI3K, AKT, P27, GSK3β in the PI3K/Akt signaling pathway. 16S rRNA sequencing revealed that the HTQS formula reduced the abundance of the genus Family_XIII_AD3011_group, which was positively correlated with IR and taurodeoxycholic acid. In addition, Lachnospiraceae_UCG_010 inversely correlated with TC and five bile acids, which could be essential to the therapeutic effect of the HTQS formula against NAFLD. Conclusions The HTQS formula proved to be an effective pharmacotherapy for NAFLD without causing liver or kidney injury. Multiple potent components of the HTQS formula could alleviate liver steatosis and lipid metabolism disorder by modulating the PI3K/Akt signaling pathway and restoring gut microbiota composition.

Oligoasthenospermia is the primary cause of infertility. However, there are still enormous challenges in the screening of critical candidates and targets of oligoasthenospermia owing to its complex mechanism. In this study, stem cell factor (SCF), c-kit, and transient receptor potential vanilloid 1 (TRPV1) biosensors were successfully established and applied to studying apoptosis and autophagy mechanisms. Interestingly, the detection limit reached 2.787 × 10^-15 g/L, and the quantitative limit reached 1.0 × 10^-13 g/L. Furthermore, biosensors were used to investigate the interplay between autophagy and apoptosis. Schisandrin A is an excellent candidate to form a system with c-kit similar to SCF/c-kit with a detection constant (K_D) of 5.701 × 10^-11 mol/L, whereas it had no affinity for SCF. In addition, it also inhibited autophagy in oligoasthenospermia through antagonizing TRPV1 with a K_D of up to 4.181 × 10^-10 mol/L. In addition, in vivo and in vitro experiments were highly consistent with the biosensor. In summary, high-potency schisandrin A and two potential targets were identified, through which schisandrin A could reverse the apoptosis caused by excessive autophagy during oligoasthenospermia. Our study provides promising insights into the discovery of effective compounds and potential targets via a well-established in vitro-in vivo strategy.

Objective:To detect the expression of fibroblast-specific protein 1 (FSP1/S100A4) , ɑ-smooth-muscle actin (ɑ-SMA) and fibroblast-activated protein (FAP-ɑ) in tumor-associated fibroblasts (TAFs) in papillary thyroid carcinoma (PTC) , and to investigate its relationship with the origination and development of PTC.Methods:The expression of FSP1/S100A4, ɑ-SMA and FAP-ɑ in normal thyroid and PTC was determined by SP method of immunohistochemistry, and the relationship between these indicators and important clinicopathological parameters were analyzed.Results:The positive expression of FSP1/S100A4, ɑ-SMA and FAP-ɑ was observed in PTC, but not detected in the follicular epithelium or stromal cells of normal thyroid. In addition, the expression of FAP-ɑ was significantly related to tumor size, lymph node metastasis and TNM classification ( χ2=6.833, P<0.05; χ2=10.296, P<0.05; χ2=4.910, P<0.05) . The expression of ɑ-SMA was positively related to the invasion of capsule and lymph node metastasis ( χ2=6.008, P<0.05; χ2=11.766, P<0.05) . The expression of FSP1/S100A4 was negatively related to the clinicopathological parameters above ( P>0.05) in PTC. Conclusion:TAFs in PTC may indicate the infiltration and metastasis, which provideds new thinking for the treatment strategies of papillary thyroid carcinoma.

PURPOSE: The importance of long noncoding RNAs (lncRNAs) in tumorigenesis has recently been demonstrated. However, the role of lncRNAs in development of thyroid cancer remains largely unknown. MATERIALS AND METHODS: Using quantitative reverse transcription polymerase chain reaction, expression of three lncRNAs, including BRAF-activated long noncoding RNA (BANCR), papillary thyroid cancer susceptibility candidate 3 (PTCSC3), and noncoding RNA associated with mitogen-activated protein kinase pathway and growth arrest (NAMA), was investigated in the current study. RESULTS: Of the three lncRNAs (BANCR, PTCSC3, and NAMA), expression of BANCR was significantly up-regulated while PTCSC3 and NAMA were significantly down-regulated in papillary thyroid carcinoma (PTC) compared to that in normal tissue. BANCR-knockdown in a PTC-derived cell line (IHH-4) resulted in significant suppression of thyroid stimulating hormone receptor (TSHR). BANCR-knockdown also led to inhibition of cell growth and cell cycle arrest at G0/G1 phase through down-regulation of cyclin D1. In addition, BANCR was enriched by polycomb enhancer of zeste homolog 2 (EZH2), and silencing BANCR led to decreased chromatin recruitment of EZH2, which resulted significantly reduced expression of TSHR. CONCLUSION: These findings indicate that BANCR may contribute to the tumorigenesis of PTC through regulation of cyclin D1 and TSHR.

OBJECTIVETo investigate the methylation in promtor region of RASSF2 and sFRP1 in sporadic colorectal cancer patients in order to provide screening method for early colorectal cancer.

METHODSThe methylation in promoter region of RASSF2 and sFRP1 in serum samples of 59 sporadic colorectal cancer patients and 59 healthy volunteers was detected by methylation specific PCR. The association between clinicopathological features of sporadic colorectal cancer patients and methylation in promoter region of RASSF2 and sFRP1 was analyzed.

RESULTSThe methylation rates of RASSF2 and sFRP1 gene in serum of 59 sporadic colorectal cancer patients were 27.1% and 30.5%, significantly higher than those in healthy volunteers(0%, both P<0.01). The methylation of RASSF2 or sFRP1 occurred in 29(49.2%) patients, which was significantly higer than the methylation rate of single gene(P<0.05). No association was found between methylation ratio of RASSF2 and sFRP1 and clinicopathological features in sporadic colorectal cancer patients.

CONCLUSIONSMethylation in promoter region of RASSF2 and sFRP1 is often detected in serum of colorectal cancer patients. The combination detection of methylation for the two genes may provide information for early screening of colorectal cancer.

Objective To summarize the experience of intraoperative neuromonitoring (IONM) system for monitoring and protection of recurrent laryngeal nerve (RLN) during thyroid surgery.Methods A total of 220 cases were enrolled in this study (53 males and 167 females),with the median age of 38.2 years old.There were 85 cases of thyroid cancer,19 cases of thyroid benign tumor,90 cases of thyroid goiter,3 cases of Hashimoto's diseases,and 23 cases of hyperthyroidism.113 cases had tumors larger than 5 cm in diameter.During the procedure,2 recording needle electrodes were put in cricothyroid muscle and 1 stimulator electrode was explored in tracheoasophageal groove.If any RLN was fight there or nearby,doctors can see the electromyogram and hear the toothonk.With careful dissection,RLN can be found out till exploring into the larynx site.Results Electromyogram showed in 207 cases (278 nerves),and it didn't show in 13 cases,among whom 9 cases were false-negative because of system or annesthesia problems,4 cases didn't manage to have needle electrodes put in properly due to cricothyroid muscle being invaded.No permanent RLN paralysis occoured.Transient nerve paralysis occurred in 2 cases,who recovered in 1 month after operation.Conclusion IONM system is an effective way to avoid damage to RLN in thyroidectomy.

ObjectiveTo evaluate the safety and effectiveness of fast track surgery (FTS) in l aparoscopy-assisted radical distal gastrectomy (LADG) for gastric cancer.MethodsSixty-one patientswith distal gastric cancer were randomly divided into three groups:FTS + LADG group (n =19) undergoing LADG and FTS treatments,LADG group (n =22) undergoing LADG and traditional perioperative cares,and FTS + ODG ( open distal gastrectomy) group ( n =21 ) undergoing ODG and FTS treatments.FTS treatments included avoidance of mechanical bowel cleansing,restrictive perioperative intravenous infusion,early ambulation,early enteral nutrition.The age,sex,body weight,anastomotic mode,number of lymph node dissected,and tumor stage,serum albumin (ALB),blood urea nitrogen (BUN),C-reaction protein (CRP),flatus time,postoperative hospital stay,medical cost,and postoperative complications were compared between three groups. ResultsThe level of ALB in FTS + LADG group were higher than in LADG group at the 4th and 7th day after surgery ( P ＜ 0.05,P ＜ 0.01 ).Compared to LADG group,the variation of ALB from preoperation to 4th day after surgery in FTS + LADG group and FTS + ODG group was significant( P ＜ 0.01,P ＜ 0.05 ).CRP level between FTS + LADG group and FTS + ODG group were different significantly at 4th and 7th day after surgery ( P ＜ 0.05,P ＜ 0.05).FTS + LADG group has earlier recovery of gastrointestinal peristalsis than other two groups ( P ＜ 0.05,P ＜ 0.05 ).The medical cost in FTS + LADG group was less than in LADG group ( P =0.003 ),but higher than in FTS + ODG group (P ＜0.01 ).ConclusionsThe practice of FTS in LADG was safe,effective,improves nutritional status,eases stress reaction,accelerates gastrointestinal peristalsis and postoperative rehabilitation.

Objective To explore the efficiency of transcervical video-assisted mini-incision thyroidectomy for thyroid tumor. Methods 53 patients with thyroid tumors who underwent the video-assisted mini-incision thyroidectomy from Jan. 2006 to Dec. 2009 in the Department of Thyroid Surgery, Yantai Yuhuangding Hospital,were retrospectively studied. Results All of the patients, except 5 cases converting to open thyroidectomy, underwent the video-assisted mini-incision thyroidectomy successfully. The temporary recurrent laryngeal nerve injury occurred in 1 patients. The subcutaneous fluid accumulation occurred in 3 patients. The skin burns around the incisions occurred in 3 patients. There was no complication of hematoma, hypocalcemia, or superior laryngeal nerve injuries. The follow-up period was from 3 months to 35 months. There was no evidence of recurrence and metastasis by postoperative ultrasonic and CT scan and radioiodine scintigraphy. Conclusions The video-assisted mini-incision thyroidectomy is feasible, safe, and with the advantage of cosmetic results. For thyroid tumor,especially thyroid cancer, longer follow-up is necessary to draw definitive conclusion on recurrence and survival rate.
