Objective To compare the efficacy of modified Chevron osteotomy and Scarf osteotomy in the treatment of moderate to severe hallux valgus.Methods A total of 76 patients with moderate to severe hallux valgus admitted to the Department of Hand and Foot Microsurgery,the First Affiliated Hospital of Xinxiang Medical University from January 2018 to January 2022 were selected as the research subjects.According to the surgical method,the patients were divided into modified Chevron osteotomy group(n=39,41 feet)and Scarf osteotomy group(n=37 feet).The patients in the modified Chevron osteotomy group received modified Chevron osteotomy treatment,the patients in the Scarf osteotomy group received Scarf osteotomy treatment.The hallux valgus angle(HVA),the 1st and 2nd inter metatarsal angle(IMA)and the distal metatarsal articular angle(DMAA)under weight-bearing conditions of patients in the two groups before and 6 months after surgery were recorded.The orthopedic effect of patients was evaluated by using the American Orthopaedic Foot and Ankle Society(AOFAS)score,and the pain level of patients was evaluated by using the visual analogue scale(VAS)score before and 6 months after surgery.The osteotomy healing time and postoperative complications of patients were compared between the two groups.Results There was no statistically significant difference in HVA,IMA,DMAA and AOFAS,VAS scores of patients before and 6 months after surgery between the two groups(P＞0.05).Six months after surgery,the HVA,IMA,and DM A A of patients in the two groups were significantly lower than those before surgery(P＜0.05),the AOFAS score was significantly higher than that before surgery(P＜0.05),and the VAS score was significantly lower than that before surgery(P＜0.05).The osteotomy healing time of patients in the modified Chevron osteotomy group and Scarf osteotomy group was(3.23±0.49)and(3.49±0.69)months,respectively;there was no statistically significant difference in the osteotomy healing time of patients between the two groups(t=-1.874,P＞0.05).The patients in both groups did not experience any vascular or nerve damage during the surgery,the surgical incision and osteotomy healed in one stage,and there were no complications such as incision infection,delayed osteotomy healing,or nonunion.Two patients(4.9％)in the modified Chevron osteotomy group experienced postoperative metastatic metatarsal pain,and the symptoms were significantly improved after treatment with targeted therapies such as blocking and physical therapy.One patient in each of the two groups experienced discomfort caused by loose internal fixation.The recurrence rates of hallux valgus in the modified Chevron osteotomy group and Scarf osteotomy group were 19.5％(8/41)and 2.6％(1/38),respectively;the recurrence rate of hallux valgus in the Scarf osteotomy group was significantly lower than that in the modified Chevron osteotomy group(x2=5.567,P＜0.05).Conclusion The modified Chevron osteotomy and Scarf osteotomy have similar therapeutic effects in correcting deformities,improving ankle function,and alleviating pain in the treatment of moderate to severe hallux valgus,and both surgical methods have few postoperative complications.However,the recurrence rate of hallux valgus after modified Chevron osteotomy is significantly higher than that after Scarf osteotomy.

Objective:To investigate the clinical features of patients with epilepsy in Neurosurgery Outpatient and influencing factors for their seizure control.Methods:Six hundred and seventy-three epilepsy patients admitted to Neurosurgery Outpatient of 6 hospitals including Fifth Affiliated Hospital of Zhengzhou University from September 2017 to December 2022 were chosen. Clinical data (including general demographic data, education level, onset age, onset cycle and duration, course of onset, family annual income and seizure control) were collected using a questionnaire prepared by He'nan Epilepsy Systematic Diagnosis and Treatment Center to summarize the clinical features. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for their seizure control.Results:(1) In these 673 epilepsy patients, 50 (7.4%), 78 (11.6%), 192 (28.5%), 100 (14.9%), 68 (10.1%), 72 (10.7%) and 113 (16.8%), respectively, were <1 year old (infant stage), 1-2 years old (children stage), 3-5 years old (preschool stage), 6-16 years old (juvenile stage), 17-39 years old (young stage), 40-64 years old (middle-aged stage) and ≥65 years old (elderly stage). In the past medical treatment history, 23.0% (155/673) patients did not receive intervention, 72.4% (487/673) received medication, and 4.6% (31/673) received surgical treatment; 55.9% (376/673) had good seizure control and 44.1% (297/673) had poor seizure control. (2) Secondary education ( OR=2.199, 95% CI: 1.037-15.221, P=0.033), primary education or below ( OR=3.544, 95% CI: 2.101-21.343, P=0.012), daily seizures ( OR=4.788, 95% CI: 1.369-33.103, P=0.011), each seizure lasted ≥3 min ( OR=4.179, 95% CI: 3.338-18.550, P=0.003), course of disease≥3 years ( OR=0.199, 95% CI: 0.077-0.602, P=0.001), course of disease for 1-3 years ( OR=0.379, 95% CI: 0.108-0.882, P=0.031), and currently taken antiepileptic drugs for 3 or more ( OR=6.237, 95% CI: 2.195-17.837, P=0.001) were independent risk factors for poor seizure control in epilepsy patients. Conclusion:In Neurosurgery Outpatient, children with diseases before childhood enjoy the largest proportion; drug therapy remains the main treatment; low education level, short seizure cycle, long duration of attack, long course of disease, and multiple drugs used in these patients imply poor anti-epileptic effecacy.

Objective:To analyze the focuses and shortcomings of the long-term care policy for disabled elderlies in China, for references to optimize such policies.Methods:The data came from the policy documents on long-term care for disabled elderlies published on respective official websites of various ministries and commissions from January 1, 2013 to April 20, 2022. Text quantitative analysis was used to extract policy clauses, and three types of policy tools(including 13 types of sub-tools) were used to analyze these provisions.Results:132 clauses were extracted from a total of 34 policy documents, of which the number of clauses of supply, demand and environmental policy tools were 28(21.21%), 25(18.94%) and 79(59.85%) respectively. There were few clauses on scientific and technological information support(5) and capital investment(3) in the supply-type policy tools; In terms of demand-based policy tools, there were only a few clauses for government purchase(5), pilot projects(3) and service outsourcing(2); In terms of environmental policy tools, there were only a few clauses for standard design(9) and supervision and management(7).Conclusions:The long-term care policy structure of the disabled elderly in China was not balanced, the supply-based policy tools had less scientific and technological information support, the demand-based policy tools were short and single, and the environment-based policy tools were widely used but lack of standard design. Relevant policy-making departments should further improve the accuracy of policy targets, optimize the internal structure of policy tools, pay attention to the application of scientific and technological information policies and clarify the relevant standards of care services.

Objective:To analyze the cognition and willingness of family physicians on contracted service, and to explore the implementation obstacles and feasible strategies of implementing contracted service of family physicians from the perspective of suppliers.Methods:From July to October 2020, 850 family physicians in community health service centers or township health centers in three cities of Shandong Province were investigated by questionnaire survey and key person interview. Descriptive analysis and binary logistic regression model were used to analyze the willingness of family physicians to provide contracted service. Through questionnaire survey and key person interview, the implementation obstacles and service optimization strategies of family physicians were discussed.Results:791 valid questionnaires were obtained, of which 688(87.0%) approved the implementation of family physician contract service, and 679(85.8%) expressed willingness to provide family physician contract service. Marital status, recognition of service policy, satisfaction of service operation effect, optimistic degree of service development prospect and residents′ first choice of illness were the factors influencing family physician′s service willingness.Conclusions:We should effectively improve the family doctor′s service intention and promote the efficient and orderly implementation of family doctor′s contract service policy through enriching policy supporting measures, innovating the application of " Internet plus" , increasing personnel training, optimizing performance appraisal work and creating favorable public opinion environment.

Objective:To explore the current status of medical preventive integration at primary medical institutions, analyze the problems of medical prevention integration, and put forward optimization suggestions.Methods:From June to July 2020, 169 primary medical institutions in a city were selected as the survey objects to conduct a questionnaire survey on the basic information of institutions and the evaluation indicators of medical preventive integration. The evaluation index system of medical preventive integration was divided into a factual survey and a sensory survey. In addition, 32 relevant personnel were interviewed on the current situation of medical preventive integration at primary medical institutions. The reliability and validity of the data were tested and analyzed, while descriptive analysis and classification extraction analysis were carried out.Results:The reliability and validity analysis proved the data reliability. The factual survey extracted three common factors, namely organization management, performance appraisal distribution and information management. The sensory survey extracted two common factors, namely working mode and personnel training. In terms of organization, management and working methods, the degree of medical preventive integration was low. Among them, 53.8% of the institutions had formulated the medical preventive integration norms, and only 41.4% of them had shared residents′ health information in time.Conclusions:The degree of medical preventive integration of primary medical institutions in the city still need to be improved. In the future, we should strengthen the top-level design, establish the norms and cooperation mechanism of medical preventive integration, improve the awareness of medical preventive integration of medical personnel, improve the information level, and to build a new service model integrating disease prevention, medical treatment and health management.

Objective:To analyze the association between thyroglobulin antibody (TgAb) and differentiated thyroid cancer (DTC) metastases detected by post-radioactive iodine (RAI) therapy scan, when stimulated thyroglobulin (sTg) <1 μg/L.Methods:A total of 314 (68 males, 246 females, age (44.5±12.5) years) post-thyroidectomy DTC patients whose sTg <1 μg/L between March 2013 and May 2017 in Henan Cancer Hospital were enrolled retrospectively. Patients underwent 131I whole-body planar imaging ( 131I-WBS) and SPECT/CT imaging 5 d after 131I administration. Iodine avid metastases were compared between TgAb-positive group and TgAb-negative (TgAb<4 kU/L) group. Logistic regression analysis was conducted to assess odds ratio ( OR) for iodine avid metastases in each subgroup (Q1: 4 kU/L≤TgAb≤9.27 kU/L; Q2: 9.27 kU/L101.43 kU/L) of TgAb-positive patients, with the TgAb-negative patients as the reference. χ2 test was used to analyze the data. Results:Iodine avid metastases were found in 16.9% (53/314) of DTC patients and were more frequently in TgAb-positive group with TgAb>26.75 kU/L than TgAb-negative group (26.0%(19/73) vs 13.7%(23/168); χ2=5.382, P=0.02). Most metastases (92.5%, 49/53) occurred in cervical and mediastinal lymph nodes. The OR for iodine avid metastases was obviously high in TgAb-positive patients with 26.75 kU/L

Objective:To analyze the application of functional residual capacity (FRC)-guided optimal positive end-expiratory pressure (PEEP) in pulmonary retention in patients with acute respiratory distress syndrome (ARDS), and to explore the correlation between FRC and trans-pulmonary pressure and their predictive value for prognosis.Methods:Seventy-eight ARDS patients on mechanical ventilation admitted to department of critical care medicine of the First Affiliated Hospital of Jinzhou Medical University from March 2018 to May 2019 were enrolled. According to random number table method, the patients were divided into experimental group and the control group. PEEP of all patients were gradually increased in recruitment after fully sedation and analgesia. The best PEEP was set by monitoring FRC in the experimental group, and by monitoring maximum oxygen in the control group set. The differences before and after 30 minutes and 2 hours recruitment manoeuvres in dynamic compliance (Cdyn), oxygenation index (PaO 2/FiO 2), and mechanical power (MP) were compared between the two groups. Pearson method was used to analyze the correlation between FRC and trans-pulmonary pressure. The predictive value of FRC and trans-pulmonary pressure for 28-day mortality in patients with ARDS was analyzed by receiver operating characteristic (ROC) curve. Results:The optimal PEEP was (16.24±1.57) cmH 2O (1 cmH 2O = 0.098 kPa) in the experimental group and (14.11±1.15) cmH 2O in the control group in recruitment maneuvres, with statistically significant difference between the two groups ( t = 5.678, P = 0.000). Pearson correlation analysis showed that there was a significant correlation between FRC and trans-pulmonary pressure in ARDS patients ( r = 0.759, P = 0.000). Cdyn and PaO 2/FiO 2 in the experimental group were higher than the control group at 30 minutes and 2 hours after recruitment maneuvres [Cdyn (mL/cmH 2O): 61.16±3.55 vs. 58.54±5.25, 58.59±2.82 vs. 56.86±3.40; PaO 2/FiO 2 (mmHg, 1 mmHg = 0.133 kPa): 245.27±14.86 vs. 239.00±5.34, 192.25±5.11 vs. 188.86±5.07], MP was lower than the control group (J/min: 16.32±1.11 vs. 17.05±1.22, 15.22±1.25 vs. 17.03±1.50), the difference was statistically significant (all P < 0.05). The ROC curve analysis showed that both FRC and trans-pulmonary pressure had predictive value for the 28-day mortality of ARDS patients, and the area under the ROC curve (AUC) was 0.868, and 0.828 respectively (both P < 0.01). Conclusions:Measuring FRC in patients with ARDS during recruitment maneuvres can guide optimal PEEP. FRC was significantly correlated with trans-pulmonary pressure, and both of them had predictive value for 28-day mortality in ARDS patients.

Objective:To investigate the clinical value of 125I seeds implantation in the treatment of primary liver cancer with portal vein tumor thrombus. Methods:A total of 218 patients (184 males and 34 females, age: (53.8±9.2) years) with primary liver cancer with portal vein tumor thrombus between January 2015 and June 2018 were retrospectively analyzed. All patients underwent 125I seeds implantation under CT guidance. CT examination and liver function test were repeated 2-3 months after the implantation, and the portal vein tumor thrombus diameter, liver function parameters and ascites before and after treatment were compared. All patients were followed up for 2-26 months and the survival time were calculated. Paired t test was used for data analysis. Results:Among 218 patients, 8 patients (3.7%) had complete remission of tumor thrombus, 111 patients (50.9%) had partial remission, 80 patients (36.7%) had no change, and 19 patients (8.7%) had disease progression 2-3 months after the implantation. The total effective rate was 91.3%(199/218). The diameter of tumor thrombus after treatment was (12.63±4.64) mm, which was significantly smaller than that before treatment ((26.65±10.88) mm; t=18.74, P<0.01); serum bilirubin, the direct bilirubin after treatment were different compared with those before treatment: (20.59±10.29) vs (24.27±12.65) pg/L ( t=5.37, P<0.05), (11.40±8.37) vs (15.64±7.99) pg/L ( t=8.44, P<0.05); the indirect bilirubin after treatment was not significantly different from that before treatment ( t=0.85, P>0.05). Ascites in 86/142 patients were better after the implantation. No serious complications associated with treatment were seen. There were 162 patients died and 56 patients survived till the end of follow-up. The survival time of all patients was (9.23±0.59) months. Conclusion:125I seeds implantation can safely and effectively treat the portal vein tumor thrombus in patients with primary liver cancer, and improve the clinical symptoms such as ascites.

Objective: To evaluate the efficacy and safety of sofosbuvir (Nanjing Zhengda Tianqing Pharmaceutical Co., Ltd.) combined with ribavirin in patients with genotype 2 chronic hepatitis C virus infection. Methods: Treatment-naïve or treatment experienced genotype 2 chronic hepatitis C patients from sixteen research centers of China were screened. All subjects received once-daily dose of sofosbuvir (400 mg) combined with ribavirin (body weight < 75 kg, 1 000 mg/day, 400 mg in the morning and 600 mg in the evening; body weight > 75 kg, 1 200 mg/d, 600 mg in the morning and 600 mg in the evening) for 12 weeks. Patients were followed-up for a period of 12 weeks after discontinuation of treatment. Continuous variables were expressed as mean ± standard deviation. The proportion of subjects with virologic response at different follow-up time points and 95% confidence intervals were estimated by maximum likelihood ratio and Clopper-Pearson interval. Results: 132 cases with genotype 2 chronic hepatitis C virus infection from sixteen research centers of China were included, 12 cases of whom were associated with cirrhosis, and the remaining 120 cases were not associated with cirrhosis. One hundred and thirty-one cases completed the study, and one patient lost to follow-up at week 4 after the end of treatment. The sustained virological response rate was 96.2% (95% confidence interval: 92.37% - 99.16%) after 12 weeks of drug withdrawal. Virological relapse occurred in four cases. Of the 132 subjects enrolled in the study, 119 (90.2%) reported 617 adverse events during treatment, of which 359 (76.5%) were TEAE related to sofosbuvir and/or ribavirin. There were nine TEAEs of grade 3 and above, and six cases (4.5%) of them had six severe adverse events. Only one serious adverse event was associated with sofosbuvir and ribavirin (unstable angina pectoris). There were no adverse events leading to drug discontinuation or death. Conclusion Sofosbuvir combined with ribavirin has a high SVR rate in the treatment of genotype 2 chronic hepatitis C virus infection, and most of the adverse events occurred were mild with acceptable safety profile.
