Objective To compare the effects of two exercise intensities on metabolic syndrome(MS).Methods Forty-nine MS patients hospitalized in Taiyuan Central Hospital from December,2022 to January 2024 were selected and randomly divided into two groups:a standard group(n=24)and individual group(n=25).All patients underwent cardiopulmonary exercise test(CPET)before and after treatment,collecting major indexes including body parameter,body component,and metabolic indicator for prescribing exercise programs.The standard group was trained with exercise intensity prescribed on heart rate reserve,while the individual group received the exercise with intensity prescribed on ventilatory threshold.Both groups received equal energy consumption exercise intervention with the same exercise frequency for 12 weeks.Results The two groups demonstrated significant improvements in waist circumference(WC),body mass index(BMI),body fat related indexes,and systolic blood pressure after intervention(P<0.05).The individual group showed significant improvements inWC,BMI and body fat related indexes as compared to the standard group(P<0.05).Both groups showed significant improvements in peak oxygen uptake,(PeakVO2),peak load power(Peak WR),peak metabolic equivalent(PeakMets),and peak respiratory exchange ratio(Peak RER)after intervention(P<0.05).The individual group presented significant improvements in peak heart rate(HRpeak),peak oxygen pulse(Peak VO2/HR),and maximum voluntary ventilation(MVV)(P<0.05)after intervention.Before intervention,the standard group demonstrated significantly higher levels in PeakVO2 and Peak MET compared to the individual group(P<0.05),but after intervention the two groups showed no significant differences in the two indexes.After the intervention,the individual group demonstrated insignificant improvements in all indexes compared to the standard group(P>0.05).Conclusions Both exercise prescriptions based on CPET can effectively improve the health-related indicators of MS patients on condition of moderate exercise intensity.However,the program prescribed based on individualized ventilatory threshold shows superiority to the program prescribed based on maximum physiological value in improving these indicators.

Objective:To evaluate the fixation with a locking fibular intramedullary nail for treatment of extra-articular distal tibial fracture complicated with fibular fracture (AO/OTA 43A).Methods:A retrospective study was conducted to analyze the data of 31 patients who had been treated by fixation with a locking fibular intramedullary nail for extra-articular distal tibial fracture complicated with fibular fracture at Department of Orthopaedics, The 909th Hospital of Joint Logistics Support Force between January 2018 and December 2021. There were 20 males and 11 females; (41.5±15.7) years in age; AO classification of the distal tibial fractures: 10 cases of type 43A1, 10 cases of type 43A2, and 11 cases of type 43A3; 11 open fractures and 20 closed fractures. Fracture healing, fibular alignment, tibiotalar angle, and incidence of complications were regularly followed up and recorded after surgery. At the last follow-up, the ankle joint function was assessed using the Olerud Molander ankle score (OMAS) and the ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS).Results:All the 31 patients were followed up for (17.5±3.3) months after surgery. All of them achieved fine fracture union. The union time was (3.9±0.8) months for tibial fractures, and (3.6±0.9) months for fibular fractures. No internal fixation failure was observed. The last follow-up revealed the following: the fibular alignment was 1.8°±1.3° and the ankle tibiotalar angle 9.1°±2.3°; no fibular rotation, shortening, or separation displacement happened; the OMAS score was (88.3±6.2) points, and the AOFAS ankle-hindfoot score (87.4±6.0) points. Two patients required removal of the distal locking screw of the fibular intramedullary nail due to soreness around the lateral malleolus caused by screw loosening. There were no other related complications.Conclusion:Fixation with a locking fibular intramedullary nail is an effective treatment for extra-articular distal tibial fracture complicated with fibular fracture, demonstrating advantages of firm fixation, limited complications, minimal trauma and soft tissue irritation, and good clinical efficacy.

Objective To analyze and discuss the medication rule of professor Ruan Yan in the treatment of children with allergic rhinitis by using data mining method,and to provide reference for the clinical research and patented drugs development for the treatment of children with allergic rhinitis.Methods The outpatient medical records of professor Ruan Yan for the treatment of children with allergic rhinitis were collected.Microsoft Excel 2010 software was used for frequency statistics.SPSS Clementine 12.0 software was used for association rule analysis,cluster analysis and factor analysis to obtain the data.The frequency of use of various drugs and the association rules between drugs were obtained.Then the medication rules in professor Ruan Yan's prescription were analyzed.Results A total of 308 Chinese medicine compounds were included,involving 80 kinds of Chinese medicines,among which relieving drugs and qi-invigorating herbs were high-frequently used.The distribution of traditional Chinese medicine syndrome types was mainly characterized by lung-qi deficiency-cold syndrome and lung-spleen qi deficiency syndrome.The medicinal properties were mainly spicy,warm and sweet,and most of them belonged to the lung,spleen and stomach meridians.Five core prescriptions were extracted by factor analysis.Four drug combinations were obtained by systematic cluster analysis.Conclusion Ventilating lung and opening the orifices,expelling wind and removing cold,strengthening the spleen and replenishing qi are basic therapeutic principles for professor Ruan Yan in the treatment of children with allergic rhinitis.The treatment mainly focused on dispelling evil,ventilating lung and opening the orifices,expelling wind and removing cold during the acute stage of allergic rhinitis.In the remission period,according to the principle of"treating disease must be based on its origin",the treatment should enhance children's physical fitness,tonify lung and strengthen spleen,thereby reducing recurrence.

Objective To analyze the current status of dyslipidemia among employees in a petrochemical enterprise and its influencing factors. Methods A total of 1 636 employees from a petrochemical enterprise were selected as the research subjects by the judgment sampling method. Peripheral venous blood was collected from the research subjects to detect total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C) and low- density lipoprotein cholesterol (LDL-C) in serum. The Effort-Reward Imbalance (ERI) Questionnaire was used to investigate occupational stress in the ERI model. Results The detection rate of dyslipidemia among the research subjects was 52.7%. The detection rates of abnormal total cholesterol, triglyceride, LDL-C, and HDL-C were 35.7%, 31.4%, 24.3%, and 10.0%, respectively. The detection rate of high occupational stress among the research subjects was 26.3%. The result of multivariate logistic regression analysis showed that the risks of dyslipidemia in overweight and obese employees were higher than that of normal body mass [ odds ratio (OR) and 95% confidence interval (CI) were 2.111 (1.692-2.634) and 2.346 (1.591-3.458), both P<0.01]. The risk of dyslipidemia in lean body mass employees was lower than those with normal body mass [OR (95%CI) was 0.130 (0.030-0.564), P<0.05]. The risk of dyslipidemia in smokers was higher than that in non-smokers [OR (95%CI) was 1.462 (1.124-1.902), P<0.01]. Employees with 20-30 years and ≥ 30 years of service had higher risks of dyslipidemia than those with <10 years of service [OR (95%CI) were 1.411 (1.038-1.919) and 1.869 (1.202-2.906), respectively, both P<0.05]. The risk of dyslipidemia among employees with high effort level of occupational stress in ERI model was higher than those with low effort level [OR (95%CI) was 1.351(1.045-1.745), P<0.05]. Conclusion Dyslipidemia prevalence is relatively high among the petrochemical enterprise employees. Overweight, obesity, smoking, long service years, and occupational stress in ERI model are influencing factors of dyslipidemia. To prevent dyslipidemia, it is necessary to strengthen blood lipid monitoring and lifestyle intervention in personnel with overweight, obesity, smoking, long service years, and occupational stress in ERI model.

OBJECTIVE: To investigate the effectiveness of compression screw combined with Buttress plate through direct axillary approach for Ideberg typeⅡ scapular glenoid fractures. METHODS: A retrospective analysis was conducted on 11 patients with Ideberg type Ⅱ scapular glenoid fractures treated with compression screws combined with Buttress plate fixation through the direct axillary approach between January 2014 and June 2022. There were 7 males and 4 females, aged from 34 to 75 years, with an average of 56.0 years. The causes of injury included 4 cases of falling from height injury, 4 cases of heavy object injury, and 3 cases of traffic accident injury. The time from injury to operation was 2-5 days, with an average of 3.8 days. The operation time, intraoperative blood loss, hospital stay, complications, and fracture healing time were recorded. The Constant-Murley score, American Society of Shoulder and Elbow Surgeons (ASES) score, and shoulder joint flexion, abduction, external rotation (neutral position), and internal rotation (neutral position) range of motion were used to evaluate shoulder joint pain and function. RESULTS: The operation time was 45-105 minutes, with an average of 79.0 minutes; the intraoperative blood loss was 80-200 mL, with an average of 99.2 mL; the hospital stay was 3-8 days, with an average of 5.8 days. One patient had poor wound healing after operation, and the wound healed after strengthening dressing change; the rest wounds had primary healing, and no axillary nerve paralysis occurred. Except for 1 patient lost follow-up, the remaining 10 patients were followed up 10-54 months, with an average of 26.4 months. The postoperative X-ray film examination showed that the fractures healed well within 8-15 weeks, with an average of 11.0 weeks. There was no complication such as fracture displacement, internal fixator failure or fracture during follow-up. At last follow-up, the patient's shoulder joint flexion, abduction, external rotation (neutral position), and internal rotation (neutral position) range of motion, Constant-Murley score, and ASES score significantly improved when compared with those before operation ( P<0.05). CONCLUSION Compression screw combined with Buttress plate through direct axillary approach is an effective way to treat Ideberg typeⅡ scapular glenoid fracture, with advantages of small trauma, concealed incision, and good effectiveness.

Objective:To evaluate the safety and feasibility of neoadjuvant chemotherapy (NACT) combined with radical surgery for elderly patients with locally advanced gastric cancer (LAGC).Methods:One hundred and fourty eight patients with LAGC after NACT and gastrectomy between 2012 and 2020 were retrospectively reviewed. They were divided into two groups: (1) <65 years old (111 cases) and (2) ≥65 years old (37 cases) and their clinicopathological and prognostic data were compared.Results:There was no significant difference between the two groups in the incidence of hematological complications such as anemia ( χ2=0.235, P=0.628), leukopenia ( χ2=0.613, P=0.434), neutropenia ( χ2=0.011, P=0.918) and thrombocytopenia ( χ2=0.253, P=0.615) and non-hematological complications such as nausea ( χ2=0.092, P=0.762), vomiting ( χ2=0.166, P=0.683), diarrhea ( χ2=0.015, P=0.902) and mucositis ( χ2=0.199, P=0.766) due to NACT. There were no statistical differences between the older patients and the younger in operation duration ( t=0.270, P=0.604), intraoperative bleeding ( t=1.140, P=0.250) and R 0 resection rate ( χ2=0.105, P=0.750). The incidence of postoperative complications was 25.2% and 37.8% in the younger patients and the olders ( χ2=2.172, P=0.141). Pleural effusion ( χ2=7.007, P=0.008) and pulmonary infection ( χ2=10.204, P=0.001) was significantly higher in the older patients than in the youngers. The 3-year progression-free survival rate ( t=0.494, P=0.482) and 3-year overall survival rate ( t=0.013, P=0.908) were comparable between the two groups. Conclusions:NACT combined with radical surgery is safe and effective in elderly patients with LAGC, except for higher perioperative pulmonary-related complications.

Background The thyroid gland is one of the organs sensitive to ionizing radiation, and there are few studies on the effects of long-term exposure to low doses of ionizing radiation on the thyroid gland of radiation workers. Objective To investigate thyroid abnormalities in workers in medical radiology departments in Guangdong Province and to identify potential influencing factors of thyroid abnormalities. Methods A total of 1657 radiation workers from 48 hospitals in Guangdong Province were selected as survey subjects using convenience sampling, and their personal dose monitoring results and health examination information were retrospectively analyzed to determine the factors affecting thyroid abnormalities. Results The M (P₂₅, P₇₅) of thyroid absorbed dose (D_T) was 1.55 (0.65, 3.96) mGy in the 1657 investigated workers. The attribute-specific medians of D_T were 1.29, 1.38, 1.99, and 3.51 mGy for departments of diagnostic radiology, interventional radiology, radiotherapy, and nuclear medicine, respectively; and 1.10, 1.55, and 1.80 mGy for job titles of nurse, technician, and physician, respectively. Differences in D_T by gender, age, years of radiological work, age of radiation exposure onset, occupational category, and job title were statistically significant (Z=−6.35, H=708.52, 918.20, 31.19, 95.64, 39.28, P<0.05). The positive rate of thyroid abnormalities in investigated workers was 46.53% (771/1657). Among them, the positive rate of abnormal thyroid function was 22.87% (379/1657), that of abnormal thyroid morphology was 33.98% (563/1657), and that of thyroid nodule was 26.55% (440/1657). The differences in thyroid abnormality rates by gender, age, years of radiation work, age of radiation exposure onset, D_T, and job title of radiation workers were statistically significant (χ²=51.89, 49.64, 20.54, 18.29, 12.07, 16.16, P<0.05). The differences in abnormal thyroid function positive rate by gender, age of radiation exposure onset, and job title were statistically significant (χ²=26.21, 6.21, 8.32, P<0.05). The differences in the positive rates of abnormal thyroid morphology and nodules were statistically significant by gender, age, years of radiological work, age of radiation exposure onset, D_T, and job title (abnormal thyroid morphology, χ²=40.24, 64.17, 37.63, 15.17, 19.28, 15.05; nodules, χ²=31.41, 77.98, 42.11, 19.16, 21.70, 13.52, P<0.05). The positive rates of thyroid abnormality, thyroid morphology abnormality, and nodules all showed a linear increasing trend with increasing age, years of radiation work, and age of radiation exposure onset (P<0.05). The results of logistic regression analysis indicated that the factors influencing thyroid abnormalities were female (OR=2.17, 95%CI: 1.72-2.74), increased years of radiological work (OR=1.04, 95%CI: 1.03-1.06), onset of radiation exposure in age groups of 30-34 and ≥35 years (OR=1.63, 95%CI: 1.12-2.37; OR=2.58, 95%CI: 1.74-3.29), and working in department of diagnostic radiology (OR=1.40, 95%CI: 1.07-1.84). Conclusion Long-term exposure to low doses of ionizing radiation has an effect on thyroid abnormalities in medical radiation workers. Among them, being female, physicians, and working in department of diagnostic radiology are at a higher risk of abnormal thyroid function; being female, increased years of radiation work, and radiation exposure onset at age ≥30 years are associated with a higher risk of reporting abnormal thyroid morphology.

Objective:To observe the clinical efficacy of acupuncture plus point application in managing pain after thoracoscopic radical lung cancer surgery(TRLCS). Methods:A total of 120 patients undergoing TRLCS were randomized into a treatment group and a control group,with 60 cases in each group.Both groups received patient-controlled intravenous analgesia(PCIA)to relieve postoperative wound pain.The control group did not receive any other interventions.The treatment group started acupuncture treatments 4 h after the surgery with point application between two acupuncture sessions;the acupuncture treatment was conducted 4,24,48,and 72 h after the surgery.At the above 4 time points,the visual analog scale(VAS)score and additional PCIA drug consumption were recorded.The 5-hydroxytryptamine(5-HT)content in the peripheral blood was determined 4 h and 72 h after the surgery. Results:The treatment group was superior to the control group in comparing the total effective rate(P<0.05).After the intervention,the VAS score decreased in both groups(P<0.05);the VAS score presented different decreasing patterns at each time point in the two groups,and the score dropped more significantly in the treatment group than in the control group(P<0.05).The total PICA drug consumption varied in the two groups after the surgery;the additional analgesic consumption was notably smaller in the treatment group than in the control group(P<0.05).The decrease in the 5-HT content in the peripheral blood also varied in the two groups;the peripheral blood 5-HT content was significantly lower in the treatment group than in the control group(P<0.05). Conclusion:Acupuncture plus point application can significantly relieve wound pain after TRLCS.

Objective:To evaluate the clinical outcomes of additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Sixty-nine patients with early gastric cancer who underwent ESD and were diagnosed as having non-curative resection by postoperative pathology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2020 were included in the retrospective observation. Patients were divided into the additional surgery group ( n=12) and the follow-up group ( n=57). The differences in clinical and pathological data of the two groups, the surgical outcomes of the additional surgery group, three-year recurrence-free survival and tumor-specific survival of the two groups, and the independent risk factors affecting three-year recurrence-free survival in the follow-up group were analyzed. Results:Compared with the follow-up group, the rates of submucosal infiltration [66.7% (8/12) VS 21.1% (12/57), χ 2=7.927, P=0.005], vascular invasion [33.3% (4/12) VS 1.8% (1/57), P=0.003] and nerve invasion [16.7% (2/12) VS 0.0% (0/57), P=0.028] in the additional surgery group were significantly higher. In the additional surgery group, the interval between the additional surgery and ESD was 18.5 d (7-55 d), the surgical time was 286.4±85.9 min, and the number of dissected lymph nodes was 25.6±7.4. Four patients (33.3%) had residual tumor. Postoperative complications occurred in 4 patients (33.3%) (all were discharged after conservative treatment), and there was no perioperative death. One patient developed liver metastases 17 months after the surgery, and died 22 months after surgery due to liver metastases. One patient died 22 months after surgery due to non-tumor causes. The three-year recurrence-free survival and three-year tumor-specific survival in additional surgery group were 91.7% (11/12) and 91.7% (11/12), respectively, and those in the follow-up group were 87.7% (50/57) and 100.0% (57/57), respectively. Multivariate Cox regression analysis showed that tumor size ≥2 cm was an independent risk factor for three-year recurrence-free survival in the follow-up group ( P=0.037, HR=15.595, 95% CI: 1.181-205.952). Conclusion:Additional surgery and close follow-up are safe and feasible therapeutic strategies for early gastric cancer patients who underwent non-curative ESD. Clinicians should make reasonable choice based on the pathological results, patients' physical condition and surgery intention. But for patients with primary tumor size ≥2 cm, additional surgery is recommended.
