Objective To investigate the clinical efficacy of shoulder-three-points warm needling moxibustion plus conventional rehabilitation in recovery from arthroscopic rotator cuff repair.Method Seventy patients who had undergone arthroscopic rotator cuff repair for rotator cuff injury were enrolled and randomly allocated to groups A and B, 35 cases each. Group A received conventional rehabilitation and group B, shoulder-three-points warm needling moxibustion in addition. Functional activity and pain in the affected shoulder were scored using the American Shoulder Elbow Scale (ASES), the University of California at Los Angeles (UCLA) Shoulder Scale and the Constant-Murley Shoulder Outcome Score in the two groups before and after treatment.Result There were statistically significant pre-/post-treatment differences in the ASES, UCLA and Constant-Murley scores in the two groups (P<0.01). After treatment, the scores were higher in group B than in group A, but there was no significant difference in the UCLA function subscore (P>0.05) and a significant difference in the UCLA pain subscore (P<0.01) between groups A and B. Conclusion shoulder-three-points warm needling moxibustion plus conventional rehabilitation training can markedly promote postoperative rehabilitation and especially relieve postoperative pain in patients with rotator cuff injury. It provides a new idea for clinical shoulder rehabilitation in the future.

Aim To explore the effects of salvianolic acid B(SAB) and tanshinone ⅡA(TA) alone or the compatibility of these two effective components on the proliferation of rat vascular adventitial fibroblasts, and to observe the effects of the compatibility of the two on cell proliferation with the stimuation of angiotensin Ⅱ(Ang Ⅱ).Methods The effects of SAB and TA alone or the compatibility of the two on cell proliferation were detected by methyl thiazolyl tetrazolium(MTT) method, and flow cytometry was adopted to detect cell cycle with or without the induction of Ang Ⅱ.Results It was shown that SAB and TA alone could inhibit fibroblast proliferation in different degree.Through a series of concentration screening, three effective concentrations were obtained respectively and then the inhibition of cell growth was detected by Pairwise compatibilities.The results showed that the compatibility of TA(10-8 mol·L-1) and SAB(10-5 mol·L-1) had the most significant inhibitory effect(P<0.01), and they could inhibit cell proliferation, further flow cytometry was adopted to detect drug effects on cell cycle, the results indicated that the compatibility of SAB and TA mainly blocked the cells in G0/G1 phase.Induced by Ang Ⅱ, the compatibility of SAB and TA group, compared with Ang Ⅱ group, blocked thee cells in G0/G1 phase;and compared with combination of SAB and TA group, it mainly blocked cell cycle in S phase.Conclusion SAB and TA have certain inhibitory effect on fibroblast proliferation, also they could inhibit the proliferation induced by Ang Ⅱ, mainly by blocking the cells in G0/G1 phase.

Objective To investigate the clinical efficacy of Dahuang Xiaozhi Suppository in treating chronic abacterial prostatitis/chronic pelvic pain syndrome (CABP/CPPS) of moist heat and blood stasis syndrome. Methods Two hundred patients of CABP/CPPS were randomly divided into control group and observation group, 100 cases in each group. 2 groups were disabled anti-infective meidicne and other preparations, and received diet and life intervention. The control group received the treatment of Qianliean Suppository, and the observation group received the treatment of Dahuang Xiaozhi Suppository, one capsule each time, once a day, into the anus depth of about 3–4 cm. Ten days were a treatment course with two day interval between each course of treatment. The treatment lasted for three courses. The clinical efficacy of the two groups was observed and compared. The indexes including the scores of NIH-CPSI, leukocyte count and lecithin corpuscles in prostatic fluid, and urinary flow rate were evaluated. Results The total effective rate was 100% (100/100) in the observation group and 78% (78/100) in the control group, and the observation group was much higher than control group (P<0.05). The scores of NIH-CPSI and leukocyte count in both groups were significantly lower after treatment (P<0.01), and those in observation group weresignificantly lower than those in control group (P<0.01). The cases with lecithin corpuscles++++in both groups were significantly more after treatment (P<0.01), and those in observation group were significantly more than those in control group (P<0.01). The peak flow rate and mean flow rate in both groups were higher after treatment (P<0.01), and it was higher in observation group (P<0.01). Conclusion The efficacy of Dahuang Xiaozhi Suppository in treating CABP/CPPS of moist heat and blood stasis syndrome is remarkable, and it is better than Qianliean Suppository.

Objective To quantitatively compare the diagnostic capability of 68Ga-NGR and 18F-FDG in well-differentiated hepatocellular carcinoma (HCC) bearing mice by microPET/CT imaging.Methods The in vitro cellular uptake, in vivo microPET/CT imaging and biodistribution studies of 68Ga-NGR and 18F-FDG were quantitatively compared in SMMC-7721-based well-differentiated HCC.The human fibrosarcoma (HT-1080) and human colorectal adenocarcinoma (HT-29) cells/xenografts were respectively used as positive and negative reference groups for CD13.The expression of CD13 was qualitatively verified by immunohistostaining.The levels of CD13 and glucose-6-phosphatase (G6Pase) were semi-quantitatively analyzed by Western blot test for all 3 types of tumors.Two-sample t test was used for data analysis.Results The in vitro cellular uptake showed that the 68Ga-NGR uptake in SMMC-7721 and HT-1080 cells was higher than that in HT-29 cells, and the 68Ga-NGR uptake was higher than 18F-FDG uptake in SMMC-7721 cells.The in vivo microPET/CT imaging results revealed that the uptake of 68Ga-NGR in SMMC-7721 tumor was (2.17±0.21) %ID/g, remarkably higher compared to (0.73±0.26) %ID/g of 18F-FDG uptake (t=8.826, P<0.01).The tumor/liver ratio of 68Ga-NGR was 2.05±0.16, which was 2.03-fold higher than that of 18F-FDG.In the HT-1080 tumors, the uptakes of 68Ga-NGR and 18F-FDG were both high, and the values were (2.46±0.23) %ID/g, (3.47±0.31) %ID/g.The uptake of 68Ga-NGR was significantly lower than that of 18F-FDG in HT-29 tumors: (0.67±0.20) %ID/g vs (3.17±0.29) %ID/g;t=4.221, P<0.01.Western blot and immunohistostaining results were as follows: HT-1080(CD13+, G6Pase-), SMMC-7721(CD13+, G6Pase+), HT-29(CD13-, G6Pase-).Conclusions The uptake of 68Ga-NGR is higher than 18F-FDG uptake in SMMC-7721 tumor bearing mice, therefore it is worthwhile to consider the feasibility of clinical translation for PET/CT in diagnosis of HCC.Furthermore, because of the difference in 68Ga-NGR and 18F-FDG avidities in tumors with different molecular phenotypes of CD13 and G6Pase, there is an underlying potential for molecular imaging in the determination of molecular phenotypes.

Objective To investigate the mechanism of renal injury induced by changes in flow shear stress (FSS) during renal ischemia/reperfusion (I/R).Methods 1.In vitro,HUVECs were divided into 4 groups:(1) HUVECs were loaded with 12 dyn/cm2 force for 30,45,and 90 min by using plate fluid chamber system.(2) Cells were loaded with FSS for 2 h,and then cultured for 1,3,8 and 12 h respectively;(3) HUVECs were pretreated with 0,1,2,4 and 8 mmol metformin and cultured for 24 h.(4) HUVECs in control group were cultured normally.The expression of p-AMPK/AMPK protein was detected by Western blotting in each group.2.In vivo,16 SD rats with successful establishment of IR model were randomly divided into 4 groups (n =4 in each group):(1) static cold storage (CS) group:isolated kidneys were stored for 4 h;(2) hypothermia machine perfusion (HMP) group:isolated kidneys were continuously perfused with 0 ℃ lactated Ringer's solution for 4 h;(3)metformin treatment group (Met-CS):metformin was intraperitoneally injected 3 days before surgery,and the isolated kidneys were obtained after cold preservation for 4 h;(4)rat kidneys of control group were just subjected to thermal ischemia for 30 min.The injury of renal tissue in each group was observed by TUNEL and HE staining.The expression and distribution of p-AMPK protein in renal tissues were detected by immunohistochemistry.The correlation between FSS loss and AMPK expression in kidney tissue was analyzed.Results The expression of p-AMPK in HUVECs could be up-regulated by FSS,and the expression of p-AMPK protein increased with the prolongation of time.After stopping FSS,the expression of p-AMPK protein in HUVECs gradually decreased with time (P＜0.05).Metformin could activate AMPK activity in a concentration-dependent manner (P＜0.05).The content of p-AMPK in renal tissue of HMP group was significantly higher than that of CS group (P＜0.05).The expression of p-AMPK in renal tissue of HMP group mainly distributed in the renal tubules,and few in glomerular endothelial cells and blood vessels.The apoptosis rate of renal tissue in HMP group was significantly lower than that in CS group (P＜0.05).In the HMP group,the damage of the renal tissue was mild,there was no swelling,and the renal tubules were slightly expanded.In the CS group,the renal tissue was severely damaged and the renal tubules were markedly swollen.Conclusion During the course of renal IR in rats,changes in FSS may affect renal tissue damage through the AMPK pathway.

Objective To evaluate left ventriclular systolic function in patients with obstructive hypertrophic cardiomyopathy (HOCM) after modified Morrow surgery using two-dimensional speckle tracking imaging (2D-STI).Methods Twenty three HOCM patients were recruited in this study.Echocardiographic data from HOCM patients during pre-operation,1-month and 3-month post-operation were analyzed by Qlab software to compare the variation in systolic function indicators 1-month and 3-month post-operation including global and 16 segmental longitudinal strain,circumferential strain and conventional echocardiographic parameters of left ventricle.Results Compared with preoperative data of HOCM patients,postoperative LVOT diameter and pressure gradient,left atrial diameter and volume index were significantly decreased(P<0.05),but there was no significant difference in left ventricular ejection fraction(P<0.05).Compared with the preoperative case,global and segmental longitudinal strain showed significant reduction after 1 week and gradually recovered after 3 months,without significant variation.The longitudinal strain of the anteroseptum reduced significantly and the longitudinal strain of the free wall increased after 3 months,however,the circumferential strain reduced significantly.The circumferential strain of basal and middle segment after 3 months had improved significantly than those of postoperative 1 week.The circumferential strain of surgical site is no obvious change and the strain of free wall was improved after 3 months.Conclusions 2D-STI can effectively evaluate global and regional systolic function of left ventricle for HOCM patients after modified Morrow surgery.

Objective: To explore the allogeneic mouse adipose-derived mesenchymal stem cell (ADSC)-microporous sheep acellular dermal matrix (ADM) on healing of wound with full-thickness skin defect in mouse and the related mechanism. Methods: One Kunming mouse was sacrificed by cervical dislocation to collect adipose tissue from inguinal region. Mouse ADSCs were isolated from the adipose tissue and cultured in vitro. Cells of the third passage were identified by cell adipogenic and osteogenic differentiation. The expressions of CD73, CD90, CD105, and CD34 were analyzed by flow cytometry. After one sheep was sacrificed, microporous sheep ADM was prepared from sheep back using decellularization method and freezing-thawing method. A 12 mm diameter, round, full-thickness skin defect wound was made on the back of each one of 36 Kunming mice. The wounds were covered by microporous sheep ADM. The mice were divided into group ADSC and control (C) group with 18 mice in each group according to the random number table after surgery. A volume of 0.2 mL DMEM/F12 culture medium containing 1×10⁶ ADSCs was injected between microporous sheep ADM and wound of mice in group ADSC. While 0.2 mL DMEM/F12 culture medium was injected between microporous sheep ADM and wound of mice in group C. On post surgery day (PSD) 12 and 17, wound healing rates of mice in the 2 groups were calculated. On PSD 7, 12, and 17, wound vascularization of mice in the 2 groups was observed under reverse irradiation of backlight. On PSD 7, 12, and 17, the wound granulation tissue of mice in group ADSC was observed by hematoxylin and eosin staining. On PSD 7, the thicknesses of granulation tissue of mice in the 2 groups was measured. On PSD 12 and 17, expressions of VEGF in wounds of mice in the 2 groups were detected by immunohistochemical method. The sample number was 6 in each group at each time point in the above experiments. Data were processed with t test and analysis of variance of factorial design. Results: (1) After 7 days of adipogenic induction, lipid droplet was observed in cytoplasm using oil red O staining. After 21 days of osteogenic induction, black deposits of calcium salts were detected using silver nitrate staining. Expression rates of CD73, CD90, CD105, and CD34 in cells were 97.82%, 99.32%, 97.35%, and 5.88% respectively. The cells were identified as ADSCs. (2) The wound healing rates of mice in group ADSC on PSD 12 and 17 [(78±6)%, (98±3)%] were significantly higher than those in group C [(60±9)%, (90±4)%, t=4.26, 4.46, P<0.01]. (3) On PSD 7, no vessel obviously grew into the center of wounds of mice in the 2 groups, while the granulation tissue has covered the wounds of mice in group ADSC. On PSD 12, the vessels were more abundant in wounds of mice in group ADSC than those in group C. On PSD 17, big vessels crossing the whole wounds was observed in wounds of mice in group ADSC, while big vessels were observed without crossing the whole wounds in wounds of mice in group C. (4) The wounds were covered with thin granulation tissue on PSD 7, and the granulation tissue began to thicken on PSD 12 and were covered by epidermis on PSD 17 in wounds of mice in group ADSC. On PSD 7, the granulation tissue in wounds of mice in group ADSC [(0.62±0.05) mm] was significantly thicker than that in group C [ (0.31±0.04) mm, t=12.27, P<0.01]. (5) On PSD 12 and 17, expressions of VEGF in wounds of mice in group ADSC [(80.7±2.2), (0.98±0.03)/mm²] were significantly than those in group C [(59.5±2.4), (81.5±2.6)/mm^2, t=15.95, 14.14, P<0.01]. Conclusions Allogeneic mouse ADSC-microporous sheep ADM can accelerate angiogenesis and growth of granulation tissue, thus promoting wound healing, which may be due to the increase of expression of VEGF.
