Objective To explore the effect of rehabilitation training on the patients after total hip arthroplasty (THA).Methods 42 THA patients were divided into the rehabilitation training group (28 cases) and control group (14 cases) according to whether receiving systemic rehabilitation training. All patients of two groups were received same basic therapy, but the cases of the rehabilitation training group were adde with systemic rehabilitation training. Scores of Harris were assessed in 1 week before operation, and 2 weeks, 3rd month and 6th month after operation. The dislocation and deep vein thrombus (DVT) were also observed. Results The scores of Harris 1 week before operation and 2 weeks after operation were not different between two groups; at the 3rd month and 6th month, the scores of the patients in the rehabilitation training group were higher than those of the control group ( P<0.05). There were fewer complication such as dislocation and DVT in the rehabilitation training group.Conclusion Rehabilitation training is very important for the THA patients to recover the function and prevent form complications.

Objective To assess the result of aortic valve replacement(AVR) for patients of severe aortic stenosis(AS)with low transvalvular gradients(TVG) and severe left ventricular dysfunction,and try to identify the determinants of survival,functional status and change in left ventricular ejection fraction(LNEF) during follow-up.Methods From 2005 to 2011,35patients with aortic valve area(AVA) ＜ 1 cm2,LN EF ＜ 0.40 and mean TVG ＜ 30 mm Hg underwent AVR in our hospital.The average age of the patients was 58 yeats old,and 88.6％ of the patients were in New York Heart Association (NYHA) functional class Ⅲ/IV at admission to the hospital.The AVA was (0.70 ± 0.09) cm2,LVEF was 0.276 ± 0.020,TVG was (26.0 ± 2.3) mm Hg,and left ventricular end-diastolic diameter (LNEDD) was (6.3 ±0.4) cm respectively.35 prosthetic valves were implanted,including 20 mechanical prostheses and 15 biological prostheses with the mean sizs of (23 ± 1) mm.Concomitant procedures included mitral valvularplasty in 5.tricuspid valve repair in 3 and coronary artery bypass grafting in 4.Results The perioperative mortaiity was 8.6％.Follow-up period was 3 to 60 monthes.The survival rates were:1-year 78％,2-year 68％,5-year 60％.LVEF increased significantly to 0.358 ± 0.047 one week postoperatively (P =0.008) and 0.426 ± 0.031 six months later (P ＜ 0.01)).LNEDD decreased to (5.7 ± 0.4) cm one week later(P =0.062) and (5.3 ±0.3)cm 6 months postoperatiwely (P ＜ 0.01).NYHA functional class improved from 88.6％ in class Ⅲ/Ⅳ to 35％ (P ＜0.01).Compared with those who surviwd during follow-up,the patients who died during follow-up were older in the year of operation[(63 ± 10) vs (54 ± 11),P =0.017],their NYHA functional class was higher[(3.9 ±0.2) vs (2.9 ±0.3),P =0.003]and the LVEDD for them in one week postoperatively was larger[(6.0 ± 1.0) cm vs (5.5 ± 0.3) cm,P =0.031].Conclusion The left ventricle contractile reserve seems to play an essential role for surgery in patients of severe aortic stenosis with low transvalvular gradients and severe left ventricular dysfunction.AVR can be performed for them with acceptable results.

OBJECTIVETo construct a recombinant adenovirus (pAdxsi-GFP-HIF) encoding human hypoxia inducible factor 1 α gene (HIF-1 α) and to express it in endothelial cells.

METHODSHIF-1 α gene was obtained from human lung cancer cell line A549, which was cultured in hypoxia condition, by RT-PCR. The HIF-1 α gene was subcloned into shuttle vector p Shuttle-CMV-EGFP at KpnI and BamHI sites. After identified with restriction enzymes, plasmid p Shuttle-GFP-HIF was linearized by digestion with restriction endonuclease I-CeuI and I-SceI, and subsequently cotransformed into E.coli DH5a with adenoviral backbone plasmid pAdxsi to make homologous recombination. After linearized by PacI, the homologous recombinant adenovirus plasmid was transfected into 293 cells to package and amplify. The recombinant adenovirus was infected with human umbilical vein endothelial cells (ECV304), and the expression level of HIF-1 α protein was evaluated by ELISA.

RESULTSThe recombinant adenovirus vector containing HIF-1 α gene (pAdxsi-GFP-HIF) was successfully constructed and amplified with titer of 3.38 X 10(10) pfu/mL. The green fluorescence protein was detected under fluorescent microscope in ECV304 at 24h after transfection and with a stronger degree after 48h. The concentration of HIF-1 protein was (48.93 ±3.86)ng/mL in supernatant at 48 h after transfection.

CONCLUSIONA recombinant adenovirus vector pAdxsi-GFP-HIF, encoding human hypoxia inducible factor 1 α gene, has been constructed in vitro and expressed successfully in ECV304 cells.

OBJECTIVE To evaluate the clinical value of contrast-enhanced ultrasonography (CEUS) in diagnosing thyroid carcinoma.METHODS The clinical data of 129 patients with thyroid nodules,who were examined by CEUS and were operated in Xinhua Hospital between Jan 2014 and Aug 2015,were analyzed in order to compare the diagnostic results of CEUS to the postoperative pathologic findings,and to summarize its imaging features.RESULTS A total of 132 thyroid nodules in 129 patients were examined by CEUS.Among them,103 nodules were diagnosed as thyroid carcinoma,24 nodules were benign thyroid tumor and 5 nodules were thyroiditis.Compared with pathology results,the diagnostic accuracy,sensitivity and specificity of contrast-enhanced ultrasound is 88.6％,92.2％ and of 75.9％ respectively.The diagnosis of the CEUS in 31 cases was not consistent with the pathological results,in which 8 cases of thyroid carcinoma were misdiagnosed as benign tumor,3 cases of thyroiditis were misdiagnosed as thyroid carcinoma,and 20 cases of benign tumors were misdiagnosed as thyroid carcinoma.The malignant thyroid nodules mainly were papillary carcinoma,which was characterized by'low enhanced'and'slow in fast out'performance in the contrast-enhanced ultrasound examination.CONCLUSION The contrast-enhanced ultrasound examination in diagnosing thyroid carcinoma has much more specificity and sensitivity,the'low-enhanced'and'slow in fast out'signs of the CEUS were the important features of malignant thyroid nodules.

Objective: To study and analyze the effect of applying the knowledge, attitude/belief, and practice (KAP) nursing mode in caring for patients who receive fixed orthodontic treatment. Methods : A total of 112 patients who received orthodontic treatment were selected as study subjects. They were randomly divided into an observation group and a control group, with 56 patients in each group. Patients in the control group were treated with conventional oral care, while those in the observation group were treated with the KAP nursing mode. The patients’ awareness of the disease, treatment compliance, and orthodontic complications were compared between the two groups. Results : After treatment with the KAP nursing mode, the disease cognition score was significantly higher in the observation group than in the control group (P < 0.05). Patient compliance was better in the observation group than in the control group throughout the treatment. Patients in the observation group were more able to return to the hospital on time than those in the control group. The orthodontic plaque index (OPI) of patients in the observation group decreased during the treatment. The OPI of patients in the observation group was significantly lower than that of patients in the control group at 6 months (t=2.344) and 12 months (t=3.721) after the start of the treatment (P < 0.05), and the incidence of orthodontic complications in the observation group was 7.1% (4/56), significantly lower than that in the control group (26.9% (15/56); χ2=9.728, P < 0.05). Conclusion Application of the KAP nursing mode can effectively reduce the incidence of complications in patients with fixed orthodontics, improve the oral health of patients, and positively affect orthodontic treatment.

Objective:To investigate the prevalence, risk factors and outcomes of diastasis recti abdominis (DRA) in multiparas after the second delivery.Methods:From June 2017 to September 2019, 300 multiparas with an average age of (31.7±4.0) years (26 to 43 years) after the second delivery were recruited at 6 weeks postpartum from two hospitals in Wenzhou. There were 171 multiparas with two natural births,36 multiparas with one natural birth and one caesarean delivery, and 93 multiparas with two caesarean deliveries. The interrectus distance (IRD) was measured with palpation at 6 weeks, 6 months and 12 months after delivery. Data on age, height, weight before pregnancy and delivery, baby′s birth weight, abdominal circumference before pregnancy and delivery, fetus number, delivery mode and occupation type were collected. Strength and endurance of abdominal muscle was assessed using manual muscle testing and curl-ups, low back pain was assessed using Oswestry disability index(ODI), urinary incontinence was assessed with International Consultation on Incontinence guestionnaire-incontinentia urinae (ICIQ-UI) short form (ICIQ-SF), and quality of life was assessed using 36-item short form health survey (SF-36).Results:Prevalence of DRA was 51.7%(155/300), 39.3%(116/295) and 27.7%(80/289) 6 weeks, 6 months and 12 months after delivery, respectively. Logistic regression analysis indicated that age ( OR=1.39, 95 %CI:1.02-1.91, P=0.38), abdominal circumference ratio ( OR=2.31, 95 %CI:1.23-4.33, P=0.01), twins ( OR=11.41, 95 %CI:2.15-60.76, P<0.01), and cesarean section ( OR=1.44, 95 %CI:1.06-1.95, P=0.02) were the risk factors of DRA at 12 months after delivery. At 12 months after delivery, the multiparas with DRA had weaker strength and endurance of abdominal muscle ( Z=-3.62, P<0.01; Z=-8.91, P<0.01), more serious low back pain ( Z=-2.10, P=0.04), and lower quality of life on physical health ( t=-3.34, P<0.01) than the multiparas without DRA. No difference in prevalence and severity of urinary incontinence and quality of life on psychological health was found when comparing multiparas with and without DRA (χ 2=0.66, P=0.42; Z=-1.18, P=0.24; t=0.91, P=0.36). Conclusion:Multipara after the second delivery has great likelihood for DRA.Age, abdominal circumference ratio, twins, and cesarean section are the risk factors of DRA. DRA is related to abdominal muscle dysfunction, low back pain, and quality of life.

The present study developed an oral hepatocyte growth factor (HGF) gene therapy strategy for gastric ulcers treatment. An attenuated Salmonella typhimurium that stably expressed high HGF (named as TPH) was constructed, and the antiulcerogenic effect of TPH was evaluated in a rat model of gastric ulcers that created by acetic acid subserosal injection. From day 5 after injection, TPH (1 × 10⁹ cfu), vehicle (TP, 1 × 10⁹ cfu), or sodium bicarbonate (model control) was administered orally every alternate day for three times. Then ulcer size was measured at day 21 after ulcer induction. The ulcer area in TPH-treated group was 10.56 ± 3.30 mm², which was smaller when compared with those in the TP-treated and model control groups (43.47 ± 4.18 and 56.25 ± 6.38 mm², respectively). A higher level of reepithelialization was found in TPH-treated group and the crawling length of gastric epithelial cells was significantly longer than in the other two groups (P < 0.05). The microvessel density in the ulcer granulation tissues of the TPH-treated rats was 39.9 vessels/mm², which was greater than in the TP-treated and model control rats, with a significant statistical difference. These results suggest that TPH treatment significantly accelerates the healing of gastric ulcers via stimulating proliferation of gastric epithelial cells and enhancing angiogenesis on gastric ulcer site.
