Objective:To study the clinical effect of Maizhiling tablets combined with salmon calcitonin in the treatment of elderly femoral neck fracture after artificial femoral head replacement and the influencing factors of hip joint function 6 months after operation.Methods:Prospective research methods were used in this article.A total of 84 elderly patients with femoral neck fracture who underwent artificial femoral head replacement in the Affiliated Hospital of North China University of Science and Technology from January 2017 to June 2019 were selected and randomly divided into the treatment group (41 cases) and the control group (43 cases) by the random number table method.The treatment group was treated with Maizhiling tablet and salmon calcitonin nasal spray plus basic calcium; the control group was treated with basic calcium.Independent sample t test was used to compare the visual analogue score (VAS) on the 5th day after operation, the time of complete disappearance of congestion in thigh, and the time of first ambulation after operation between the two groups.The bone mineral density (BMD) of contralateral femoral neck and Harris score of hip joint function were compared between the two groups at 14 days, 3 months and 6 months after operation by repeated measurement variance analysis.Multivariate Logistic regression was used to analyze the influencing factors of hip joint function at 6 months after operation.Results:VAS score on the 5th day after surgery: (6.34±1.54) points in the treatment group and (7.02±1.50) points in the control group.Complete regression time of thigh congestion: (12.12±2.27) d in the treatment group and (13.88±2.58) d in the control group.The first postoperative activity time was (5.93±1.52) d in the treatment group and (7.84±1.05) d in the control group, and the differences of the above indexes between the two groups were statistically significant ( t value was 2.051, 3.313, 6.673, respectively, all P<0.05). The BMD values of the contralateral femoral neck in the treatment group were (0.543±0.123), (0.561±0.119), (0.606±0.105) g/cm 2 at 14 days, 3 months and 6 months after operation, and (0.530±0.092), (0.517±0.089), (0.526±0.090) g/cm 2 in the control group.The results of variance analysis of repeated measurements showed that Fintra-group=55.726, P<0.01; Finter-group=4.206, P<0.05; Finteraction=57.654, P<0.01.There were significant differences between 3 months, 6 months and 14 days after operation in the treatment group (all P<0.01), and between 3 months and 6 months after operation ( P<0.01). In the control group, there was significant difference between 14 days and 3 months ( P<0.01), and between 3 months and 6 months ( P<0.01); 6 months after operation, the difference was statistically significant ( P<0.01). The Harris scores of hip joint in the treatment group were (82.12±8.18), (85.49±6.61), (87.10±6.57) points and (78.91±5.75), (81.44±6.42), (83.67±6.97) points in the control group.The results of repeated measurement ANOVA showed that Fintra-group=64.526, P<0.01; Finter-group=6.529, P<0.05; Finteraction=0.501, P>0.05.There were significant differences between 3 months, 6 months and 14 days after operation (all P<0.01). There were significant differences between 3 months and 6 months after operation ( P<0.05). There were significant differences between the groups 14 days, 3 months and 6 months after operation ( P<0.05 or P<0.01). Multivariate logistic regression analysis showed that age( OR=1.318, 95% CI1.002-1.732, P=0.048) and treatment method ( OR=29.168, 95% CI 1.030-824.623, P=0.048) were risk factors for hip function on the replacement side, and Harris score of hip function 14 days after surgery ( OR=0.624, 95% CI 0.447-0.873, P=0.006) were protective factors for hip function 6 months after surgery. Conclusion:Maizhiling tablets and salmon calcitonin nasal spray have good effects on removing blood stasis, relieving pain, effectively improving bone mineral density and promoting the recovery of joint function after artificial femoral head replacement for senile femoral neck fracture.The younger age of patients, postoperative treatment with Maizhiling tablets combined with salmon calcitonin and good recovery of hip function in 14 days after operation are the protective factors of good hip function in 6 months after operation.

The patients with higher level of education ,the longer daily use ,binaural status obtained more scores than those of the low degree of education ,the shorter daily use ,and monaural status( P< 0 .01) .The older people felt better than the youngers(P<0 .01) .The patients with long -time perceived hearing difficulty got more scores than those with short -time perceived hearing difficulty (P<0 .01) .In general ,the degree of education ,and the daily use time were the main factors influencing the effects of hearing aids .Conclusion There are many factors that influence the effects of hearing aids ,in which the degree of education ,daily use time are the main factors ,and the combination of the two factors obtain the effects of hearing aid maximization ,and the binaural status ,the short time of perceived hearing difficulty and the older obtain better satisfaction .The gender doesn't significantly influence the effects of the hearing aids .

Objective To investigate the clinical efficacy and mechanism of vacuum-assisted closure (VAC) in the preoperative and postoperative treatment of bedsore united with skin flap.Methods Twenty two cases with bedsore were randomly divided into experimental and control groups.In the control group,the surgery of flap was performed after the treatment of continuous negative pressure about 7-10 days and the VAC was not applied after operation.While in the experimental group,VAC was not used before operation.It was applied on flaps as soon as sutured the border of flap and decubitus ulcers and removed after 7-10 days.By comparing the general appearance of two groups,microvessel count and the detection rate of bacterial culture and other indicators,the clinical effects of two treatments were investigated and the preliminary mechanism was analyzed.Results After preoperative VAC treatment,11 cases of control group showed a little granulation tissue growth,less subcutaneous hematoma and wound effusion,increased microvessel count and negative bacterial culture.However,there were 4 cases of death cavity residual,subcutaneous hematoma and wound effusion,positive bacterial culture and another 4 cases of delayed healing with skin flap repairing bedsore.The application of VAC in experimental group showed close contact of flap with the basement,less effusion,increased microvessel count and negative bacterial culture.One case of skin flap had a small area of separation,after the dressing of skin and the flap survived.The other wounds healed by first intention.Conclusions The use of VAC to repair bedsore can reduce the number of operation,and it is beneficial to the flap survival.

Objective:To explore the relationship between end-dialysis over-weight (edOW) in initial stage of hemodialysis and long-term prognosis in maintenance hemodialysis patients.Methods:The data of initial uremia patients receiving hemodialysis in the First Affiliated Hospital, College of Medicine, Zhejiang University from January 1, 2008 to April 30, 2017 were retrospectively analyzed. The end point of follow-up was death or until April 30, 2018. The general data including age, gender, body mass index, primary disease, complications and laboratory indicators of the patients and the related parameters of dialysis from four to twelve months were collected. Kaplan-Meier method was used to analyze survival rate. Cox multivariate regression was used to analyze the relationship between edOW and all-cause mortality and cardiovascular disease (CVD) mortality.Results:A total of 469 patients (300 males, 64.0%) were enrolled, with age of (56.9±17.1)years old. During the follow-up period of (4.1±2.4) years (1.0-10.3 years), 102 patients died. The main cause of death was cardiovascular and cerebrovascular events, accounting for 44.1% (45/102). The value of edOW was (0.28±0.02) kg. The patients were divided into edOW<0.28 kg group ( n=292) and edOW≥0.28 kg group ( n=177) according to the mean value of edOW. Kaplan-Meier survival analysis showed that the long-term survival rate in edOW<0.28 kg group was higher than that in edOW≥0.28 kg group (Log-rank χ2=4.134, P=0.043), and the CVD mortality in edOW≥0.28 kg group was significantly higher than that in edOW<0.28 kg group (Log-rank χ2=11.136, P=0.001). Cox multivariate regression analysis showed that high edOW was an independent influencing factor for all-cause death and CVD death in hemodialysis patients ( HR=1.541, 95% CI 1.057-2.249, P=0.025; HR=1.930, 95% CI 1.198-3.107, P=0.007). Conclusion:High edOW in early phase is an independent influencing factor of all-cause and CVD death in hemodialysis patients.
