Objective To investigate the practice effect of WeChat software on extended care for patients with anterior resection syndrome. Methods From August 2014 to August 2015, 50 patients with anterior resection syndrome were chosen as control group. From September 2015 to August 2016, 50 patients with anterior resection syndrome were chosen as experimental group. Patients in experimental group could use WeChat software independently. Control group got extended care by telephone, while experimental group was carried out through WeChat platform. They were followed up for 6 months. WeChat software offered patients professional guidance on evaluation and exercise methods of defecation function by video and text with some figures. The questions from patients were answered through WeChat software during followed up. Results The defecation function after 1 month of surgery for patients with excellent, good, average, poor was 15, 20, 12, 3 cases respectively in the experimental group, and 9, 15, 19, 7 cases respectively in the control group. The defecation function after 3 month of surgery for patients with excellent, good, average, poor was 19, 21, 8, 2 cases respectively in the experimental group, and 12, 18, 17, 3 cases respectively in the control group. The difference of the defecation function after 1,3 months of surgery were statistically significant (χ2=8.395, 8.251, P<0.05). But the difference of the defecation function after 6 months of surgery had no statistical significance (χ2=7.505, P>0.05). The compliance of medication, diet and rehabilitation exercise, regular review after 6 months of surgery for patients was (2.14 ± 0.72), (7.21 ± 1.63), (11.20 ± 0.63), (5.04 ± 0.78) points respectively in the experimental group, and (1.37 ± 0.58), (5.72 ± 1.32),(9.75 ± 1.56),(4.72 ± 0.43)points respectively in the control group, and the differences were statistically significant (t=2.68-5.75, P< 0.01).Conclusion WeChat software can improve defecation function and treatment compliance, thus greatly improve the quality of life of patients with mid-low rectal cancer.

BACKGROUND:Ultrasound therapy can relieve pain and improve the movement function in patients with knee osteoarthritis, but there lacks of consistency in the literatures of ultrasound therapy.
OBJECTIVE:To further identify the effectiveness of ultrasound therapy in the treatment of knee osteoarthritis.
METHODS:Twenty-four rabbits were randomly divided into three groups:normal group, model group and ultrasound group. The rabbit in the normal group received no intervention;rabbits in the model group received anterior cruciate ligament transaction to establish the knee osteoarthritis model without any treatment;the rabbit in the ultrasound group received ultrasound therapy after modeling for 10 minutes once time, once per day, 0.3 W/cm2 , 1 MHz and treated for 10 times. Hematoxylin-eosin staining was conducted for histological observation of rabbit articular cartilage;western blot and reverse transcription PCR assessment were used to assess the expressions of caspases-3 and caspases-8 in rabbit articular cartilage, while Terminal deoxynucleotidyl transferase dUTP nick end labeling was used to assess the ratio of chondrocytes apoptosis of rabbit knee articular cartilage.
RESULTS AND CONCLUSION:The normal rabbit cartilage tissues and chondrocytes were neatly arranged in column;the middle cartilage layer of the model was thin;the chondrocytes were arranged disorderly and became less. After ultrasound therapy, the chondrocytes were rearranged neatly, and the number was increased. Compared with the normal group, the Mankin scores in the model group and ultrasound group were higher;the apoptotic rate of chondrocytes was higher in the model group and ultrasound group than in the normal group, and was also higher in the model group than in the ultrasound group. Compared with the normal group, the expressions of caspases-3 and caspases-8 were higher in the model group and the ultrasound group, while decreased after ultrasound therapy. The results indicate that ultrasound can improve the structure of cartilage tissues, decrease the expressions of caspases-3 and caspases-8 and reduce the apoptosis rate of chondrocytes. It is effective for the treatment of knee osteoarthritis with ultrasound therapy.

Objective To characterize the static balance and limits of stability (LOS) of postmenopausal women and evaluate the relationship between bone mineral density (BMD) and balance.Methods Sixty women more than 12 months past menopause and aged 50 to 60 years were included in the study.Group 1 (n =20) consisted of women with normal BMD,group 2 (n =20) women with osteopenia,and group 3 (n =20) women with osteoporosis.The static balance of all the participants was evaluated in upright postural situations for 60 s with the eyes open and with the eyes elosed.Their LOS was quantified using a force platform.Results There was no significant difference in static balance parameters or LOS among the 3 groups.The static balance parameters were not significantly different in either the eyes-open or eyes-closed situation in the osteoporosis and osteopenia groups.The medial and lateral LOS were greater than the anterior and posterior limits in all 3 groups.The anterior LOS was greater than the posterior limits among the women with osteopenia and normal density.Conclusion In postmenopausal women aged 50 to 60 years,BMD did not show any significant association with static balance or LOS.Postmenopausal women had better postural control in the mediolateral than in the anteroposterior direction.In postmenopausal women with osteoporosis,postural control in the anterior direction deteriorates from age 50 to 60.

Objective: To compare the convergent sliding of bilateral pectoral myocutaneous lfap method and conventional method for treating the early stage median sternotomy wound dehiscence in patients after cardiac surgery. Method: A total of 36 relevant patients treated in our hospital from 2010-04 to 2014-04 were studied and they were divided into 2 groups: Conventional group, the patients received sufficient draining and dressing changes followed by interrupted simple suture,n=16 and Convergent sliding group, the patients received convergent sliding of bilateral pectoral myocutaneous lfap,n=20. The clinical conditions after treatment were compared between 2 groups. Results: There were 6 patients received re-suture after the ifrst debridement because of poor healing in Conventional group, no such event happened in Convergent sliding group, P<0.05. All patients were discharged and no death occurred. In Conventional group and Convergent sliding group, the open drainage time were (7.2 ± 3.2) days and (3.3 ± 1.1) days,P<0.05; hospital stay time from the first debridement and suture were (10.4 ± 5.4) days and (8.2 ± 1.9) days,P>0.05; the median hospital stay time from discovering wound problem to wound healing and discharge were 13.0 (10.75, 19.5) days and 12.0 (10.0, 13.0) days, P>0.05. Conclusion: Compared to conventional method, convergent sliding of bilateral pectoral myocutaneous lfap method may obtain the better success rate of wound debridement and suture by shorter time for treating the early stage median sternotomy wound dehiscence in patients after cardiac surgery.

Objective To analyze the clinical and pathological data and prognosis of microalbuminuria IgA nephrology patients with decreased serum C3 level, and investigate the significance of decreased serum C3 level in microalbuminuria IgA nephrology patients. Methods Clinical and pathological data of microalbuminuria IgA nephrology patients confirmed by renal biopsy and followed up more than 6 months were reviewed. The patients were divided into decreased serum C3 level group (34 cases, 25.19%) and normal serum C3 level group (101 cases, 74.81%) according to the serum C3 level. Twenty-four hours urine protein quantitative > 1 g, or normal serum creatinine level turning into abnormal level at renal biopsy, or doubling of serum creatinine level was defined as the end point of follow-up. Renal survival was calculated by Kaplan-Meier survival analysis and risk factors of progression were analyzed by Cox regression models. Results Total of 135 microalbuminuria IgA nephrology patients were followed up successfully, with an average follow-up time (53.4 ± 21.9) months. There were 27 cases (79.41%) and 32 cases (31.68%) in the decreased serum C3 level group and the normal serum C3 level group respectively at the endpoint. Kaplan-Meier survival analysis showed that the median survival time was significantly shorter in decreased serum C3 level group compared with that in normal C3 level group: (46.7 ± 9.1) months vs. (68.4 ± 9.9) months, P =0.014. Cox regression analysis showed that abnormal serum creatinine (RR = 1.147, 95% CI: 1.129-1.395, P = 0.008), decreased serum C3 level (RR=1.028, 95%CI:0.672-1.495, P=0.039), urine protein quantitative>1 g/24 h (RR=2.066, 95%CI:1.242-3.838, P=0.006) and renal biopsy pathological indicators Lee classⅢ-Ⅴ(RR=2.820, 95%CI:1.249-5.638, P=0.041), glomerular sclerosis or adhesions (RR=1.232, 95%CI: 1.065-1.520, P = 0.040), renal interstitial atrophy or interstitial fibrosis (RR = 2.604, 95% CI:1.748- 4.104, P = 0.037), endocapillary cell proliferation (RR = 0.872, 95% CI: 0.491- 1.275, P =0.042), crescentic (RR = 1.528, 95% CI: 1.073- 2.385, P = 0.009) affected prognosis of microalbuminuria IgA nephropathy as the independent risk factors. Conclusions The clinical and pathological features in patients of microalbuminuria IgA nephropathy with decreased serum C3 level is more severe, and the prognosis is poor. The patients should be followed up closely and early intervention treatment and early active control of microalbuminuria should be done at the same time.

Objective:This study aimed to construct a lentiviral expression vector for microRNA-194 and investigate its effect on the metastasis of human osteosarcoma cell line U2-OS. Methods:Pri-and mature miR-194 amplified by PCR were inserted into the plenty-GFP vector and identified by restriction endonuclease digestion and nucleotide sequencing. The osteosarcoma cell line U2-OS was transfected with the lentivirus. Then, the stable transfected cells were used in Transwell and wound healing assay. Results:Restric-tion analysis and sequencing showed that the recombinant lentiviral expression vector was constructed correctly. The titers of obtained overexpression and suppression expression recombinant lentivirus were 1.5*108 and 4*108 TU/ml. Cell metastasis ability was signifi-cantly different in different experimental groups (P<0.01). Conclusion:The lentiviral expression vector for microRNA-194 was suc-cessfully constructed. MicroRNA-194 could influence the metastasis of the osteosarcoma cell line U2-OS;thus, it could be further ex-plored as a potential target in osteosarcoma therapy.

To observe the growth of rat bone marrow mesenchymal cells (BMMCs) on decellular bovine pericardia in vitro and to investigate the effect of proteins pre-coating on cells retention and proliferation, bovine pericardia were decellularized using trypsin, DNase and Triton X-100 respectively. Then three proteins (fibronetin (FN), gelatin, collagen I) were coated on the surfaces of the bovine pericardia separately. BMMCs were harvested from rat thighbone marrow , then expanded and seeded onto decellular bovine pericardia with the proteins pre-coated . Decelluar bovine pericardia without coating were used as controls. The retention and growth of BMMSCs were observed by Hochest staining and analyzed by MTT method. It was shown that the retention and proliferation of BMMCs on FN group and gelatin group were significantly enhanced comparing with those on collagen I group and control group (P < 0.001). There was no significant difference between FN group and gelatin group (P > 0.05), nor between collagen I group and control group (P > 0.05). We conclude that the retention and proliferation of seeding cells on FN and gelatin could be significantly improved on decellular bovine pericardia (DBP) but not on collagen I.
