Objective:To analyze and compare the clinical efficacy of minimally invasive modified Bristow-Latarjet and Bankart prosthesis in the treatment of recurrent shoulder dislocation.Methods:A total of 58 patients with recurrent shoulder dislocation treated in the Hubei Minzu University Affiliated Minda Hospital from October 2019 to December 2022 were retrospectively selected, and 29 patients underwent minimally invasive modified Bristow-Latarjet (Latarjet group) and 29 patients underwent Bankart prosthesis (Bankart group). The basic conditions of surgery, postoperative shoulder joint activity, and postoperative Rowe Shoulder Function Score (Rowe score) of the two groups were compared. The shoulder function recovery of the patients was evaluated using the American Shoulder and Elbow Association Scoring (ASES) system and the University of California at Los Angeles (UCLA) shoulder joint scoring system, and the incidence of complications between the two groups were compared.Results:The operation time, incision length, intraoperative bleeding volume, recovery working time, and reset loss in the Latarjet group were shorter than those in the Bankart group: (45.56 ± 12.18) min vs. (70.35 ± 18.14) min, (4.04 ± 0.82) cm vs. (6.75 ± 0.95) cm, (61.54 ± 8.88) ml vs. (86.07 ± 7.53) ml, (13.31 ± 3.21) weeks vs.(16.24 ± 3.33) weeks, (0.97 ± 0.19) mm vs.(1.24 ± 0.35)mm, there were statistical differences ( P<0.01). The outreach and forward angles in the Latarjet group were higher than those in the Bankart group: (138.25 ± 10.36)° vs. (98.15 ± 9.64)°, (140.14 ± 10.43)° vs. (93.79 ± 8.84)°, there were statistical differences ( P<0.01). The total effective rate in the Latarjet group was higher than that in the Bankart group: 96.55%(28/29) vs. 75.86%(22/29), there was a statistical difference ( χ2 = 5.22, P = 0.022). The Rowe scores after operation in the Latarjet group were higher than that in the Bankart group: (82.52 ± 15.89) scores vs. (66.78 ± 15.34) scores, there was a statistical difference ( P<0.01). The scores of self-assessment and physician assessment of ASES system and UCLA shoulder scores after operation in the Latarjet group were higher than those in the Bankart group: (36.13 ± 8.45) scores vs. (30.17 ± 8.48) scores, (40.03 ± 9.54) scores vs. (34.25 ± 8.74) scores, (32.08 ± 2.44) scores vs. (27.49 ± 2.56) scores, there were statistical differences ( P<0.05). The complication rate in the Latarjet group was lower than that in the Bankart group: 6.90%(2/29) vs. 31.03%(9/29), there was a statistical difference ( χ2 = 5.50, P = 0.019). Conclusions:The minimally invasive modified Bristow-Latarjet in the treatment of recurrent dislocation of the shoulder joint is superior to Bankart prosthesis in terms of shoulder functional recovery and postoperative rehabilitation.

Objective To investigate the age-related changes of biomechanical properties for humerus, femur and tibia in male rats and their application values in age estimation. Methods According to different weeks of age, 90 healthy male SD rats were divided into 2, 4, 6, 8, 17, 26, 52, 78 and 104-week groups with 10 rats in eachgroup. After the rats were executed by excessive anesthesia, humerus, femur, and tibia were separated and the attached soft tissues were removed. The length of the above-mentioned bones and the diameter of the middle section (compression site) were measured with vernier caliper, and the three-point bending test was conducted with electronic universal material testing machine to detect the ultimate load and displacement under ultimate load. Results There were significant differences in the ultimate load of humerus, femur and tibia among male rats in different age groups (P<0. 05). With the increase of week age, the ultimate loads of the humerus, femur and tibia increased first and then decreased, and reached the peak value in 52-week age group, showing a strong positive correlation with week age before 52 weeks ( r = 0. 884,0. 933,0. 929, P<0. 05). There was no significant difference in humerus and tibia. The displacement of femur under ultimate load was weakly positively correlated with week age (R= 0. 406,P<0. 05). The age prediction accuracy for automatic linear modeling of ultimate load for humerus, femur, tibia and three above-mentioned bones in rats before 52-week age was 78. 2% , 86. 8% , 84. 1% and 88. 3% , respectively. There was a strong positive correlation between the length of humerus, femur and tibia and the ultimate load (R= 0. 904, 0. 897, 0. 814, P<0. 05). The diameters of humerus, femur and tibia were strongly positively correlated with the ultimate load (R = 0. 759, 0. 814 and 0. 745, P<0. 05). Conclusions The ultimate loads of humerus, femur and tibia in male rats increased first and then decreased with age, and were positively correlated with age before 52 weeks, which could be used for age inference. The highest accuracy of age estimation was ultimate loads of three bones, followed by femur. The length/ middle diameter of humerus, femur and tibia were strongly positively correlated with the ultimate load.

There is a pressing need to promote the overseas innovation and development of traditional Chinese medicine (TCM) in building the "Belt and Road".However,TCM still faces great challenges in the process of internationalization at the present stage,because the backwardness of the international marketing management,cultural differences between China and the west and lack of R&D in turn.It causes indefinite international market position,low brand awareness and low international influence.Therefore,this research explored the internationalization identity of TCM in building the "Belt and Road" from the perspective of Burke's identity theory,put forward ways to realize the international identity of TCM in the aspects of experience,emotion and culture,and constructed the integrated marketing strategy framework of government marketing,industry marketing and enterprise marketing based on STP marketing tool.It would be beneficial to promote the international cognition and influence of TCM,in order to realize the TCM internationalization.

BACKGROUND:It has been an urgent problem of how to promote cartilage repair of the knee and shorten the total course through a tissue engineering approach. Fortunately, microfracture plus stem cel transplantation may open up a new path for this issue. OBJECTIVE:To investigate the clinic feasibility of arthroscopic microfracture technique plus stem cel transplantation for repair of articular cartilage injury of the knee. METHODS:From October 2010 to March 2012, a total of 16 patients with articular cartilage injury of the knee were enrol ed, including 12 males and 4 females, with the average age of 38.6 years (16-52). Al cases of cartilage injury were confirmed by arthroscopy. Autologous bone marrow was extracted from patients at 2 weeks before treatment to isolate, culture and amplify bone marrow mesenchymal stem cel s in vitro. The cel culture solution of 3-5 mL (about 107 cel s) was harvested. The articular cavity was clean by arthroscopy and microfracture technique was performed at the area of cartilage injury that was then covered with hemostatic gauze through a minimal y invasive incision and the prepared bone marrow mesenchymal stem cel s were injected. The knee was bandaged with the elastic bandage after aspirating the joint cavity effusion by vacuum suction. Functional exercises were performed early by CPM.RESULTS AND CONCLUSION:After fol ow-up of 4-18 months, there were 13 cases of excel ent, 2 cases of valid and 1 case of ineffective. According to Lysholm knee scores, the average scores were improved from 42 points (33-67 points) to 89 points (75-99 points) at 4 weeks after treatment. The function was satisfied and al patients were fol owed up without recurrence or worse. Under the arthroscopy, the combination of microfracture technique and autologous bone marrow mesenchymal stem cel transplantation is proved to be effective for articular cartilage injury of the knee and it can notably improve the clinic symptoms and recover the function of the knee.

A Cleanert Alumina-N-SPE column (0.5 g/6 mL) chromatograpy with 5 mL of chloroform-methanol (7: 3) as eluent, instead of aluminum oxide column (100-200 mesh, 5 g, 1 cm) chromatograpy eluted successively with chloroform and the chloroform-methanol (7:3) (20 mL each), was applied to enrich matrine and oxymatrine in Sophora flavescens. Also, the optimization of the HPLC determination conditions with acetonitrile-ethanol absolute-3% phosphoric acid solution (84: 6: 10) as mobile phase, instead of acetonitrile-ethanol absolute -3% Phosphoric acid solution (80: 10: 10) recorded in Chinese Pharmacopoeia 2010 Edition, was more suitable for determination of matrine and oxymatrine in S. flavescens. This method has advantage of reducing sample handling time and solvent volume and increasing the accuracy and feasibility, which can simplify the procedure for determination of matrine and oxymatrine in S. flavescens.

Objective To investigate the inhibitory effect of octreotide on transforming growth factor-alpha (TGF-?)-induced cell proliferation of human hepatocellular carcinoma cells and its possible mechanism. Methods The effect of octreotide on TGF-?-induced cell proliferation of the liver cancer cells (LCC) was evaluated by immunohistochemistry method. The effect of octreotide on TGF-? secretion and epidermal growth factor receptor(EGFR) expression in the cells was determined by reverse-transcriptase polymerase chain reaction(RT-PCR). The effect of octreotide on extracellular signal-regulated protein kinase (ERK) expression in the cells was measured by Western-blot and immunohistochemistry method. Results The TGF-?-induced expressions of proliferating cell nuclear antigen (PCNA) in nucleus were obviously increased by TGF-?. TGF-?mRNA index of hepatocellular carcinoma cells was decreased by octreotide. Octreotide inhibited significantly the expressions of EGFR mRNA induced by TGF-?. Octreotide inhibited significantly the expressions of ERK protein induced by TGF-?. There was intense staining in the nucleus of the cells by TGF-? and weak staining in the nucleus of the cells treated simultaneously by octreotide and TGF-?.Conclusions Octreotide can inhibit the secretion of TGF-?, the expression of EGFR, and the signal transduction of EGFR of LCC, and consequently exerts an inhibitory effect on TGF-?-induced hepatocellular carcinoma cells proliferation.
