Objective To study the effect of fast tract surgery (FTS) used in patients undergoing total knee arthroplasty (TKA). Methods For the experimental group, 341 inpatients with TKA in the Joint Surgery Department of Shandong Provincial Hospital from June 2014 to June 2015 were treated with FTS nursing measures. For the control group, 355 inpatients with TKA of the same department from January 2013 to May 2014 were treated with conventional nursing measures. The effects of FTS nursing measures, the parameters of patients′ postoperative complications, average hospitalization days and the function recovery of knee joint were evaluated respectively. Results After implementing the FTS nursing measures , the incidence of deep venous thrombosis of lower limbs reduced from 8.45%(30/355) to 2.35%(8/341) (χ2=2.340, P<0.05). The average hospitalization days treated without/with FTS nursing measures were:unilateral knee (14.49±3.62) days (without FTS) vs. (11.95±4.53) days (with FTS), bilateral knees (15.80± 3.01) days (without FTS) vs. (13.19±4.08) days (with FTS)(t=3.166, P<0.05). Two weeks after surgery, the HSS scores in the experimental group was 65.72 ± 5.54, while the HSS scores in the control group was 52.43 ± 7.32 (t=2.452, P < 0.05). Three months after surgery, the HSS scores in the experimental group was 88.72 ± 7.10, while the HSS scores in the control group was 72.14 ± 8.73 (t=2.528, P < 0.05). Conclusions FTS nursing measures could significantly reduce the incidence of deep venous thrombosis of lower limbs, shorten the hospitalization days of inpatients, and promote the functional recovery of knees.

Objective To evaluate the effect of early exercise intervention on deep venous thrombosis (DVT) after joint replacement.Methods 100 patients with joint replacement were divided into observation group including 50 cases and control group including 50 cases by random number table method.Early exercise intervention was used in observation group and usual nursing was used in control group.The hemodynamic index (femoral vein blood flow peak velocity and average velocity) and DVT incidence were compared between the two groups.Results After the intervention for 3 days,the femoral vein blood flow peak velocity and average velocity of observation group respectively were (43.5±4.1) cm/s and (27.3±3.2) cm/s,those of control group respectively were(36.6±3.7) cm/s and (20.2±2.8) cm/s.The difference between the two groups was statistically significant (t=2.987,2.895,P ＜ 0.05).After the intervention for 7 days,the femoral vein blood flow peak velocity and average velocity of observation group respectively were (56.1±4.7) cm/s and (32.1±3.9) cm/s,those of control group respectively were (41.3±3.9) cm/s and (22.4±4.3) cm/s.The femoral vein blood flow peak velocity and average velocity of observation group significantly higher than control group(t=3.675,2.929,P ＜ 0.05).The DVT incidence of control group and observation group respectively were 40.0％(20/50) and 14.0％(7/50),showed significant differences between the two groups(x2=8.574,P=0.003).Conclusions Using the early exercise intervention on patients with joint replacement can effectively improve the lower limb venous blood flow velocity and prevent DVT.

OBJECTIVE To study the clinical efficacy of voice training on voice recovery in patients with vocal cord polyps during perioperative period.METHODS A total of 72 patients with vocal cord polyp were chosen in this study and they were randomly divided into study group and control group. After operation, the control group received routine treatment, and the study group received voice training on the basis of routine treatment. The results of voice acoustic analysis in the two groups were compared at 8 weeks after operation.RESULTS After 8 weeks, the maximum phonation time(MPT), dysphonia severity index (DSI) and the highest frequency(F0-High) of the study group were significantly higher than that of control group (P<0.05). The fundamental frequency perturbation(Jitter) of the study group was markedly lower than that of the control group(P<0.05). There was no statistical difference in the fundamental frequency(F0), the lowest intensity(I-Low) and amplitude perturbation(Shimmer) between the two group (P>0.05).CONCLUSION Voice training in the early postoperative period of vocal cord polyps was helpful to the recovery of the voice.

Objective To investigate the clinical values of next-generation sequencing (NGS) technology in diagnosis of miscarried chorionic villi genetic disorders. Methods Patients who underwent miscarriage (n=87) were enrolled in this study. Among all patients, 32 cases were of recurrent miscarrage and 55 cases were of sporadic miscarriage. In all collected patients, 35 women were 35 years or older while other 52 women were less than 35 years old. Positive detection rate and the abnormal detection rate were compared between these two methods. Chromosomes abnormal rates were also compared among different types of miscarrage and different ages. All aborted villi tissue were analyzed by NGS of whole genome and G-band?ing karyotype. Results The successful detection rate of chorionic villi by NGS (100.00%) was higher than that of G-band?ing karyotype (74.71%), and the detection rate of abnormal chorionic villi by NGS (58.62%) was also higher than that of G-banding karyotype (50.77%). Three cases of chromosome structure anomaly were found in those 51 chromosome anomalies (5.88%). Other 48 cases of chromosome anomalies were aneuploidy anomalies (94.12%) include 39 cases of trisomy, 2 cases of double trisomy and 1 case of triple trisomy and 6 cases of monomer. On the other hand, 32 cases of chromosome aneuploi?dy anomalies were found in 33 chromosome anomalies by G-banding karyotype, which include 24 cases of trisomy, 2 cases of double trisomy, 1 case of triple trisomy, 5 cases of monomer and 1 case of chromosome structure anomaly. Most NGS re?sults (n=64) were in agreement with G-banding karyotype but with 1 case of discrepancy. Chromosomal abnormality rate de?tected by NGS in sporadic miscarrage group and recurrent spontaneous miscarrage group were 60.00%and 56.25%respective?ly. There was no significant difference (P>0.05). Chromosomal abnormality rate picked by NGS in women aged≥35 years old (71.43%) was higher than that in women<35 years old (50.00%) with statistically significant difference (P<0.05). Conclu?sion NGS technology showed highly accuracy in detecting chromosomal abnomality from villi tissue. Therefore, it could help to detect genetic disorders of miscarrage. It is useful to determine the reasons of miscarrage and guide the next pregnancy.
