Objective:To observe the clinical efficacy of combining contralateral needling and tendon-bone balancing Tuina(Chinese therapeutic massage)in treating scapulohumeral periarthritis(SP). Methods:Sixty-eight eligible participants were chosen and randomized into an acupuncture group and an acupuncture plus Tuina group,with 34 cases in each group.The acupuncture group received treatment with contralateral needling,and the acupuncture plus Tuina group was treated with contralateral needling combined with tendon-bone balancing Tuina.The post-treatment changes in the Constant-Murley score for comprehensive shoulder function,visual analog scale(VAS)score for pain,and shoulder range of motion(ROM)score were compared after 2 treatment courses to estimate the clinical efficacy in the two groups. Results:After treatment,the total effective rate was 96.7%in the acupuncture plus Tuina group versus 83.9%in the acupuncture group,showing a significant difference between the two groups(P<0.05).The Constant-Murley shoulder function score increased in the acupuncture plus Tuina group after the intervention;a decreased VAS pain score and an increased shoulder ROM score were found in both groups.After 1 and 2 treatment courses,the between-group comparisons of the Constant-Murley and shoulder ROM scores showed statistical significance(P<0.05).Regarding the VAS score,the acupuncture plus Tuina group was lower than the acupuncture group after the first treatment course(P<0.05),but there was no significant difference between the two groups after 2 treatment courses(P>0.05). Conclusion:Contralateral needling plus tendon-bone balancing Tuina can produce more significant clinical efficacy and relieve pain faster than contralateral needling alone in treating SP.

Objective To investigate the factors related to the local recurrence of spine giant cell tumor (GCT) after surgical treatment and provide a reference for the treatment.Methods A retrospective analysis of GCT of the spine from January 2000 to June 2016 was conducted.A total of 73 patients with GCT of the spine who underwent surgical treatment in Giant Cell Tumor Team of China (GTOC) were collected,including 29 males and 44 females.The average age was 33.73±11.34 years (range:13-60 years).Clinical characteristics including gender,age,history of recurrence,tumor position,Ennecking stage,Frankel score,clinical symptoms,surgery procedures,surgical approach,preoperative selective artery embolism (PAE),radiotherapy and bisphosphonate treatment history are collected.The correlation between the factors and tumor recurrence were analyzed by single factor analysis and multiple-factor logistic regression.Results The mean follow-up time was 61.81 ±53.21 months (range:4-210 months).Surgical procedures,bisphosphonate treatment,history of recurrence and radiotherapy were found significant correlation with tumor recurrence by single factor analysis.The result of multiple-factor logistic regression showed that surgical procedures (P=0.026) and bisphosphonate treatment (P=0.017) were independent risk factors for tumor recurrence.Conclusion Total spondylectomy and bisphosphonate treatment could significantly reduce the recurrence rate of GCT of the spine.

Objective: To observe the effects of Zhige oral liquid on lipid metabolism in rats with alcoholic liver disease.Methods: Alcoholic liver disease rats were induced by alcoholic gavage plus normal diet. The intervention group was given different doses of Zhige oral liquid at the same time. The control group was given alcohol and oral administration of Jiejiuling oral liquid. After 12 weeks, the rats were sacrificed and serum ALT, AST, TC, TG and liver TC and TG levels were measured. Results: Compared with the normal group, the liver index, serum ALT, AST, TC, TG and liver TC and TG levels were significantly higher in the groups except the high dose group (P ＜ 0.01 or 0.05), among which the model group and the low dose group had the most significant increase (P ＜ 0.01) . Compared with the model group, the above indicators were decreased in the high, medium and low dose groups and the control group, and the decreasing trend was the same.That is, the high dose of the Zhige oral liquid was the most significant (P ＜ 0.01), followed by the middle dose group and the control group (P ＜ 0.05) . The decrease in the low dose group was the least significant. Compared with the control group, there were significant differences in the high-dose groups (P ＜ 0.05) . Conclusion: A certain dose of Zhige oral liquid can inhibit or reduce the occurrence of alcoholic liver disease by improving lipid metabolism disorder.

Phonocardiogram exercise testing(PCGET) is a recently developed method for evaluating cardiac contractility and the cardiac reserve of patients with heart disease and of healthy subjects. In order to test the reliability of PCGET method in physical sport, the present author conducted a clinical study. The ratio of the amplitude of the first heart sound after PCGET to that recorded at rest was defined as an indicator, i.e. cardiac contractility reserve index (CCRI). PCGET was performed on 30 athletes and 30 non-athletes. The results showed that the average of CCRI was 10.139 +/- 2.631 in 30 athletes and 6.612 +/- 3.104 in 30 non-athletes. There was a significant difference between CCRI of the two groups (P < 0.01). Thus, PCGET might be a noninvasive, convenient and inexpensive technique to evaluate the cardiac reserve quantitatively for athletes.

Objective: To analyze the characteristics of acute pesticide poisoning in Ningbo, and to provide scientific basis for the prevention and control strategy. Methods: In February 2017, the pesticide poisoning report card of Ningbo from 2011 to 2016 was drawn from the China Disease Control and prevention information system. The data of the report card was organized by Excel and analyzed by SPSS19.0 software. Results: 2593 cases of acute pesticide poisoning were reported in Ningbo from 2011 to 2016, 125 deaths, and the case fatality rate was 4.82%. The productive pesticide poisoning and unproductive pesticide poisoning were 299 and 2294, respectively, the ratio was 1: 7.67. The case fatality rate were 0.33% and 5.41%, respectively. The difference was statistically significant (χ²=14.83, P<0.01). The productive Pesticide poisoning mainly occurred from July to September (55.85%) , the unproductive pesticides mainly occurred from April to June (30.64%) and July to September (30.34%). The seasonal distribution of the pesticide poisoning in the two groups was statistically significant (χ2=82.21, P<0.01). The productive pesticide poisoning in male (80.27%) was significantly higher than the proportion of unproductive pesticide poisoning (52.09%) , the differences in gender composition between the two types of pesticide poisoning was significant (χ2=84.97, P<0.01). The productive pesticide poisoning from 55 to 65 years old group was in the largest number (35.45%) , and the distribution of unproductive pesticide poisoning was uniform in each age group including 25 years old and above, the difference in age composition between two types of pesticide poisoning was statistically significant (χ2=177.84, P<0.01). All of the 10 counties of Ningbo had reports of pesticide poisoning. The counties with more reports were Ninghai county (18.28%) , Fenghua district (14.69%) and Yuyao (12.42%). The acute pesticide poisoning was mainly caused by pesticides and herbicides, mainly in organophosphorus (45.74%) and paraquat (16.81%) . Conclusions At present, the pesticide poisoning in Ningbo is given priority to unproductive pesticide poisoning currently, seasonal distribution characteristics was obvious, and occurred both in different sex and age groups, suggesting that the relevant departments should carry out targeted health education, and strengthen the management of high toxic and highly toxic pesticides.

Objective:To evaluate the clinical value of the New England spinal metastasis score (NESMS) in predicting the prognosis of patients with spinal metastases by retrospectively analyzing the medical records of multicenter spinal metastases in China.Methods:The data of 179 patients with spinal metastases from January 2008 to December 2018 were retrospectively collected. There were 108 males (60.3%) and 71 females (39.7%) with an average age of 59.79±10.88 years old (range 27-84 years). The patient demographic characteristics, primary tumor type, spinal metastases and segments, vertebral pathological fractures, neurological Frankel classification, physical function status, Karnofsky performance scale (KPS), visual analogue score (VAS), the spinal instability neoplastic score (SINS), modified Bauer score, NESMS score, Tomita score and modified Tokuhashi score were collected. The clinical value of NESMS score, Tomita score and modified Tokuhashi score in predicting the survival of patients with spinal metastases were compared. The independent factors affecting survival in these patients were analyzed by Cox proportional hazards regression model.Results:Among the 179 patients, the peak incidence of spinal metastases was in the age group of 61-75 years (45.3%, 81/179) of all patients. Lung cancer was the most common primary tumor (46.9%, 84/179). 40.8% (73/179) of patients had multi-segment metastasisand thoracic spine was the most common site with single-site metastasis (26.3%, 47/179). 28.5% (51/179) of the patients had visceral metastases and 52.0% (93/179) of the patients had extraspinal bone metastases. 31.3% (56/179) of the patients had pathological fractures of the involved vertebral bodies.114 patients received surgical treatment (63.4%). The mortality rates in 3-months, 6-months and 1-year were 22.4% (40/179), 51.4% (92/179) and 77.1% (138/179), respectively. The median survival time of patients with NESMS score of 0-3 was 3, 4, 8, and 10 months respectively with the mean survival time was 3.60±2.10, 6.77±3.39, 9.69±5.71 and 10.53±6.25 months. The 1-year mortality rates were 100% (13/13), 87.5% (42/48), 71.6% (63/88) and 66.7% (20/30) respectively. The consistency of NESMS score, Tomita score and modified Tokuhashi score in predicting survival of all patients was 0.63, 0.58 and 0.55, respectively. For patients with spinal metastases, the NESMS score was better than the Tomita score and modified Tokuhashi score in predicting survival at 3-months (AUC=1.00, 0.63, 0.42) and 6-months (AUC=0.71, 0.63, 0.45). But the accuracy of Tomita score was best in predicting survival at 1-year (AUC=0.66, 0.61, 0.38). Multivariate Cox proportional hazards regression model analysis showed that growth rate of primary tumor, neurological function Frankel score, albumin level and surgical treatment were independent factors affecting the survival time of patients with spinal metastases ( P<0.05). Conclusion:The consistency and accuracy of NESMS score in predicting survival of patients with spinal metastases are better than Tomita score and modified Tokuhashi score, especially in predicting 3- and 6-month survival. The growth rate of primary tumor, Frankel classification, albumin level and surgical treatment were independent factors affecting the survival time of patients with spinal metastases.

Objective:To retrospectively analyze the patients with spinal metastases who received surgical intervention and summarize the evolution of their clinical and pathological characteristics and surgical methods.Methods:The data of 703 patients with spinal metastases from January 2007 to December 2018 were collected retrospectively. There were 395 males (56.19%, 395/703) and 308 females (43.81%, 308/703) with an average age of 58.14±11.46 years (range 13-84 years). According to the degree of invasion and thoroughness of tumor resection, the surgical methods could be divided into minimally invasive surgery, decompression surgery, separation surgery, piecemeal resection and total en-bloc spondylectomy surgery. The operative methods were minimally invasive surgery in 89 cases (12.66%), decompression surgery in 96 cases (13.66%), separation surgery in 303 cases (43.10%), piecemeal resection in 182 cases (25.89%) and total en-bloc spondylectomy in 33 cases (4.69%). To analyze the trend of the clinical, pathological types and surgical treatment of patients with spinal metastases over the years, and determine the relevant factors affecting the decision-making of surgical methods by multivariate logistic regression.Results:The ratio of male to female was 1.28:1. 39.54% (278/703) of patients with single-segment involvement in 703 patients, 24.04% (169/703) of patients with double-segment metastasis and 36.42% (256/703) of patients with multi-segment metastasis. The most common type of primary tumor was lung cancer (34.57%, 243/703), followed by breast cancer (8.25%, 58/703), myeloma (8.11%, 57/703), gastrointestinal tumor (6.82%, 48/703) and renal malignant tumor (6.40%, 45/703). From 2007 to 2018, there was no significant difference in the percentage change of different age, gender and primary tumor source composition (age: χ 2=14.01, P=0.233; gender: χ 2=35.73, P=0.341; primary tumor: χ 2=120.09, P=0.074). The percentage of patients with sacrococcygeal metastasis decreased from 20.00% in 2008 to 1.89% in 2017 and the difference was statistically significant (χ 2=8.09, P=0.005). The percentage of patients with multi-level metastasis increased from 26.67% in 2008 to 52.83% in 2017, and the difference was statistically significant (χ 2=7.23, P=0.007). The percentage of patients with minimally invasive surgery decreased from 25.00% in 2007 to 5.88% in 2018, and the percentage of patients with segmented resection decreased from 53.33% in 2008 to 10.29% in 2018. The proportion of the two surgical methods showed a significant downward trend, and the differences were statistically significant (minimally invasive surgery: χ 2=1.46, P=0.026; segmented resection surgery: χ 2=19.56, P<0.001). The percentage of patients undergoing separation surgery increased from 13.33% in 2008 to 64.71% in 2018, and the proportion of patients undergoing total en-bloc spondylectomy increased from 0 in 2007 to 10.29% in 2018. Both surgical methods showed a significant growth trend and the differences were statistically significant (separation surgery: χ 2=27.09, P<0.001; χ 2=4.16, P=0.042). Multivariate Logistic regression analysis showed that age, metastatic site, number of metastatic segments, pathological vertebral fractures, Frankel grade, SINS score and VAS score were independent factors influencing surgical decision-making ( P<0.05). Conclusion:With different time and age, the invasiveness and thoroughness of surgery are increasing, which shows that the percentage of patients who underwent separation surgery and to-tal en-bloc spondylectomy is significantly increasing. Age, metastatic site, number of metastatic segments, pathological vertebral fractures, Frankel grade, SINS score and VAS score are independent factors affecting surgical decision-making.

Objective To analyze clinical efficacy of artificial prosthesis in giant cell tumor in distal femur,and to investigate risk factors affecting prosthesis failure and functional outcomes.Methods 42 patients with giant cell tumor of bone in distal femur,who had undergo prosthesis replacement from January 2002 to May 2015,were enrolled in this study.There were 24 males and 18 females,with an average age of 38.53± 12.87 years.There were 28 primary patients and 14 relapsed patients,including 11 cases of recurrence once and 3 cases of twice.Three-dimensional finite element model was used to analyze the effect of different angles of deviation of the spinal needle on the deformation of the bone wall.The correlations between the factors such as age,sex,occupation,prosthesis type,and other factors on prosthesis loosening were compared.Biomechanical effect of lower limbs caused by prosthesis offset angle was analyzed through gait analysis.Analyzed the effects of primary tumor or recurrence,prosthesis service status,and length of surgical osteotomy on joint function.Results A total of 42 patients were followed up by 20-158 months,with an average of 68.7 months.The 3 year survival rate of prosthesis was 83.33％ for 3 years and 57.14％ for 5 years.The major reason of prosthesis failure was loose (18/42,42.8％).X-ray films showed 19 cases of prosthetic intramedullary nail and sagittal bias of medullary force line angle ＞ 3° in the first follow-up.Osteotomy length (OR=0.132,P=0.0027) and offset angle of needle (OR=25.000,P=0.000) were significantly correlated to prosthesis loose.A length more than 12 cm and angle more than 3° were easier to result in prosthesis loose.There were no significant correlation between prosthesis failure and patients age,gender,occupation and prosthesis type.Gait analysis shows that the unsuitable bias angle of the prosthesis can significantly change the joint force of the prosthesis.The average score of MSTS 93 function evaluation was 25.43±4.256,excellent in 33 cases,good in 7 cases and poor in 2 cases.Function of patients with primary GCT were better than that of recurrent ones.Patients with one 1 times recurrence were better than that of recurrence twice (P=0.003).Patients without prosthesis loosening and revision were better than that with loosening (P=0.001).Patients with an osteotomy length less than 12 cm had a poorer function than that with more than 12 cm (P=0.002).Conclusion The main factors affecting distal femoral prosthesis replacement therapy of GCT is loosening,which was caused by broach and medullary cavity mismatch,osteotomy length,prosthesis rotation,prosthesis position.The function of the prosthesis is mainly affected by operation times,prosthesis status,osteotomy length and low patella.
