TCM medical service trade is an important component of TCM service trade. Developing TCM medical service trade has wide market and strategic importance. Development of TCM medical service trade in China is still in the initial exploring stage with small scale and dominated by the government. Recently, foreign patients prefer TCM medical serve. TCM medical service trade in abroad shows the partial and small scaled characteristics. The number of joint venture TCM treatment centers is small, and movement of personnel is rare. In order to promote the development of TCM service trade, this article proposed the following four suggestions: conducting TCM international tele-medicine service trade, developing TCM medical travel, investing more in the development of foreign TCM medical centers, expanding the scale of exporting TCM medical talents.

[Objective] To evaluate the efficacy of reinforcing short-segment pedicle screw fixation with posterior morselized bone grafting in vertebrae for spinal fusion in patients with thoracolumbar vertebrae fractures.[Method]Seventy patients with thoracolumbar vertebrae fractures were treated with short-segment pedicle screw fixation.Fractures in Group A(n =20) were reinforced with posterior morselized bone grafting in vertebrae for spinal fusion.Group B patients(n =50) were not treated with morselized bone grafting.Kyphotic deformity,anterior vertebral height,instrument failure rates,and neurological function outcomes were compared between the two groups.[Result]Kyphosis correction was achieved in Group A(morselized bone grafting) and Group B(Group A,6.4 degrees,Group B,5.4 degrees).At the end of the follow-up period,kyphosis correction was maintained in Group A but lost in Group B(Group A,0.33-degree loss,Group B,6.20-degree loss)(P=0.0001).After surgery,greater anterior vertebral height was achieved in Group A than in Group B(Group A,12.9%,Group B,2.3%)(P

TCM service trades grew rapidly and enjoyed optimistic future during the 12th five-year period, which was in good development trend. However, it is still in its primary stage of development and facing various challenges. This article argued that the development of TCM service trades will meet great opportunities, such as governmental policy encouragement, cooperation with other industries, the increasing acceptance of international market and the acceleration of internationalization of TCM. Meanwhile, there are also some difficulties - small industry scale and weak brand management, absence of legislation, lack of qualified professionals and various service trade barriers.

The deficiency in teaching resource is becoming severer as enrolled students increased and the awareness of respecting patients’rights is enhanced.It is urgent to develop new strategy to improve our diagnostic teaching in this situation.For this purpose,the scheme of developing half-dynamic interactive web for diagnostic education is proposed,and the advantage of the web are also discussed here.The advantages include enhancing students’interest and participation in study,bettering communication between the teachers and students,utilizing the collective intelligence,and integrating education resource.Excellent half-dynamic interactive web is helpful to transform the teachers’role from implanting into guiding,supervising,and examining.

BACKGROUND:The hepatic stellate cells(HSCs)plays a key role in the development of liver fibrosis.Studies have shown that bone marrow-derived mesenchymal stem cell(BMSCs)transplantation can be used to treat liver fibrosis,but the mechanism for reversal of liver fibrosis remains unknown.OBJECTIVE:To explore the mechanism of bone marrow mesenchymal stem cells to regulate the proliferation of HSCs under co-culture in vitro.METHODS:Rat BMSCs and HSCs in the experimental group were cultured in the plastic culture plate(6 holes)to establish the upper and lower double-cell co-culture system.Rat normal fibroblast cell lines were seeded as control group;HSCs were cultured alone as blank group.Cell proliferation was determined by WST8 and cell cycle was determined by flow cytometry.The Cyclin D1 and P27 mRNA expression in HSC was determined by reverse transcription-polymerase chain reaction(RT-PCR)and the level of Cyclin D1 and P27 protein by Western blot.RESULTS AND CONCLUSION:HSCs co-cultured with BMSCs significantly inhibited HSC proliferation compared with the blank and control groups at 24,48,and 72 hours(P ＜ 0.01);Flow cytometry showed that the percentage of G_0/G_1 phase cells of co-culture group was increased but the S phase cells reduced(P ＜ 0.01)compared with the other groups at 72 hours,and BMSCs blocked HSC to convert from G_0/G_1 period to S phase.After HSCs co-cultured with BMSCs for 24 hours,the expression of Cyclin D1 mRNA and protein was reduced,and significantly less than the blank and control groups at 72 hours(P ＜ 0.01);no differences were detected in P27 mRNA expression in each group during the co-culture(P ＞ 0.05).After co-culture of 24 hours,the p27 protein expression was significantly increased compared with the blank and control groups(P ＜ 0.01).BMSCs inhibited the proliferation of HSCs,possibly through inhibiting CydinDI expression,increasing the p27 protein expression to cause cell cyde arresting in G_0/G_1 phase.

An evaluation system including experiment preparation,experiment process,com-prehensive design of experiment,experiment skills and written exam was established in order to adapt to the experimental teaching reform in our school. Experimental preparation assessment was to evaluate‘preview and self-evaluation report’prepared and submitted by students. Experimental process assess-ment was to evaluate students' classroom performance and experiment reports. Assessment of compre-hensive design experiments was to evaluate the overall participation of students. Skill assessment was consisted of oral test and experiment operation test. Final written examination,mainly consisting of subjective questions,emphasized on student's flexible use of knowledge and ability to solve practical problems. The evaluation system of promoting student's learning and teacher's teaching through the examination not only fully arouse student's attention on experiment,but also make teachers more ob-jectively and really understand students' learning situation and the teaching effectiveness.

BACKGROUND:The preemptive analgesia is stil a controversial issue. Existing studies have not paid much attention to effects of preoperative factors on the hypersensitivity of peripheral and central mechanisms. Visual analog scale scores cannot subjectively and repeatedly reveal patient’s pain.
OBJECTIVE:To investigate the validity of the preventive analgesia effect of Celebrex in patients with total knee arthroplasty.
METHODS:Patients with osteoarthritis of the knee who received total knee arthroplasty were accessed by Pittsburgh sleep quality index, self-rating depression scale and self-rating anxiety scale. In al , thirty patients were enrol ed in the study. They were randomized into Celebrex group and vitamin C group, and each group had 15 patients. The patients in the Celebrex group and vitamin C group took 200 mg Celebrex and vitamin C, respectively, twice a day from day 2 to day 4. Both of their knees were evaluated by resting visual analogue scale and moving visual analogue scale in the evening of day 1 before treatment and day 3 after treatment. Meanwhile, the pain threshold and pain tolerance were accessed by a pain-threshold machine.
RESULTS AND CONCLUSION:No statistical significance of the changes of resting and moving visual analogue scale scores was found in both knees in the Celebrex group (P>0.05). The pain threshold of both knees were significantly increased (P<0.05), and the severe knee, which had less visual analogue scale scores than the minor one, turned out to increase more obviously than the minor knee (P>0.05). There were no significant changes in the pain tolerance in both knees (P>0.05). The changing values of resting or moving visual analogue scale were not significantly correlated with the pain threshold and pain tolerance (P>0.05). There were no significant changes in visual analogue scale scores, pain threshold and pain tolerance in both knees of the vitamin C group (P>0.05). Celebrex could increase the pain threshold of patients receiving total knee arthroplasty, especial y the severe knee, which indicates that the Celebrex is good for the preventive analgesia. Comparatively speaking, the pain threshold might be more sensitive than visual analogue scale in revealing the change of pain after analgesia. There is no significant correlation between visual analogue scale score and the hypersensitivity of pain.

BACKGROUND:The effect of advanced glycation end products (AGEs) on bone resorption is controversial. Our previous study has shown that bone resorption is significantly inhibited when AGEs present with pre-osteoclast cells RAW 264.7, while the effect of AGEs on osteoclastic acidification remains unknown. OBJECTIVE:To investigate the effect of AGEs on osteoclastic acidification and the underlying mechanism. METHODS:RAW 264.7 cells were induced by RANKL (15μg/L;normal group) to generate osteoclasts, and AGEs (50-400 mg/L;experimental group) or bovine serum albumin (100 mg/L;control group) were added at the beginning of the induction. The effect of AGEs on bone resorption was evaIuated by anaIyzing the area of bone resorption on the Osteo Assay Surface plates, and the effect of AGEs on osteoclastic acidification was evaluated by acridine orange staining. Furthermore, the expression levels of V-ATPase a3 and CIC-7 were detected to investigate the underlying mechanism. RESULTS AND CONCLUSION:The bone resorption area in the AGEs group was significantly decreased compared with the normal group (P<0.05). Acridine orange staining reveaIed that the red fluorescence (620 nm) intensity in the AGEs group was significantly decreased compared with the normal group (P<0.05), and this inhibitory effect became obvious with the increase of AGEs concentration. Immunocytochemistry, western blot assay and PCR findings showed that the expression levels of V-ATPase a3 and CIC-7 in the AGEs group were decreased significantly compared with the normal group (P<0.05). To conclude, AGEs exert inhibitory effect on osteoclastic acidification, probably by inhibiting the expression of V-ATPase a3 and CIC-7.
