Objective To develop the knee osteoarthritis (KOA) TCM syndrome evaluation scale. Methods Resrarch team collected subjective symptoms from all kinds of syndrome types of KOA and classified the subjective symptoms, which formed the first version of item pool containing 24 subjective symptoms. Expert questionnaires were conducted to calculate the weight coefficient of items, and formed the item pool of the Knee Osteoarthritis TCM Syndrome Evaluation Scale. According to the patient's attention to the 11 items, the items were weighted.Results The Knee Osteoarthritis TCM Syndrome Evaluation Scale contained 11 items, including pain, swelling and stiffness with different weighted scores.Conclusions The Knee Osteoarthritis TCM Syndrome Evaluation Scale were introduced to assess the KOA outcomes on the basis of TCM syndromes. It showed the characteristic of TCM and TCM syndrome.It could provide an objective and standardized measurement for TCM treating KOA.

Shanghai University of TCM was the first Chinese medicine university that established field-grade experimental teaching center in China.And both of the Chinese medicine and Chinese herbs experimental teaching centers became national experimental teaching demonstration centers.There is general improvement in laboratories conditions,so the experimental teaching team building is the critical factor of improving experimental teaching quality.The experimental teaching team of Shanghai University of TCM consists of excellent teachers as its backbone,and lecturers and technicians from fields in traditional Chinese medicine Chinese herbs and clinical practices.The team members cooperate with each other by setting up experimental teaching research groups to improve teaching quality,which plays an important role in building experimental teaching demonstration center.

OBJECTIVETo observe the distribution of constitution types of Chinese medicine (CM) in patients with osteonecrosis of femoral head (ONFH).

METHODSTotally 130 ONFH patients were recruited. Constitution types of CM were identified in all patients. Distribution features of constitution types of CM in ONFH patients were observed. The differences of distribution in gender, age, single or bilateral hips, course of disease, staging, cause, and region were also analyzed.

RESULTSSeventy patients were of complicated constitutions, while 60 patients were of single constitution. Among the 60 single constitution cases, yang-deficiency constitution [18 (13.9%)], damp-heat constitution [10 (7.7%)], blood-stasis constitution [7 (5.4%)], and qi-deficiency constitution [7 (5.4%)] were mainly distributed. Of the complicated constitutions, yang-deficiency dominated constitution occupied the top ratio [30 (23.1%)], followed by blood-stasis dominated constitution [15 (11.5%)], damp-heat dominated constitution [9 (6.9%)]. By putting them together, yang-deficiency constitution occupied the top constitution of CM [48 (36.9%)], followed by blood-stasis constitution [ 22 (16.9%)] and damp-heat constitution [19 (14.6%)]. The aforesaid three constitutions accounted for 68.5% of the total. There were no statistical distribution differences in gender, age, single or bilateral hips, course of disease, staging, or cause.

CONCLUSIONYang-deficiency constitution, damp-heat constitution, and blood-stasis constitution were liable constitutions of CM in ONFH patients.

AIM: To study the effect of ERK inhibition on the mitochondrial potential change in dexamethasone (DEX)-induced thymocyte apoptosis. METHODS: ERK activity was inhibited by PD098059 (PD), and 4 experimental groups were set: control, PD only, DEX and PD+DEX. Annexin V-FITC/PI double staining flowcytometry was used to detect apoptotic cells at time points of 3 h, 5 h and 7 h. JC-1 staining flowcytometry was adopted to examine mitochondrial membrane potential (△?m) at time points of 3 h, 7 h and 11 h. RESULTS: By stimulation with 1 ?mol/L DEX, the apoptotic rates of mouse thymocytes at 3 h, 5 h and 7 h were (19.63?0.35)%, (41.84?1.67)% and (67.00?2.43)%, respectively, and had significantly difference from control group (4.98?0.39)%, (6.08?0.33)% and (9.31?0.34)% (P0.05). At 3 h, 7 h and 11 h, the rates of low △?m cells were (21.23?1.43)%, (55.34?1.78)% and (70.88?2.87)%, significantly higher than that in control group (P0.05). CONCLUSION: DEX induces mouse thymocyte apoptosis at least partly through ERK pathway, and ERK inhibition has an important biological significance during this process.

AIM: To investigate the effects of 17?-estradiol (E 2) on the maturation and immunologic function of dendritic cells from human peripheral blood. METHODS: Cultured DCs were treated with E 2 at doses of 10 -7 mol/L and 10 -6 mol/L. The morphologic changes were observed under the scanning electronic microscope. The immunophenotype of DCs in control and treated groups was analyzed by flowcytometry. IL-12 production in culture supernatant was examined by ELISA assay. The capability of the stimulatory activity of the DCs on allogeneic T cells in mixed reaction was tested by incorporation of 3H]-TdR. RESULTS: Compared with control group, DCs cultured in the presence of E 2 displayed less dendritic pseudopod, expressed low levels of MHC-II, CD40, CD80 and CD86, and exhibited weakly activity in stimulating the proliferation of allogeneic T cells and reduction of IL-12 production. CONCLUSION: E 2 exerts a negative effect on the maturation and immunologic function of dendritic cells from human peripheral blood.

Objective: To assess left ventricular torsion function and systolic synchronization in children with hypertrophic cardiomyopathy (HCM) by using two-dimensional speckle tracking echocardiography (2D-STI), so as to provide theoretical basis for early clinical evaluation of cardiac function in children. Methods: Twenty-nine children with HCM in Shanghai Children’s Hospital, Shanghai Jiao Tong University from October 2018 to March 2019 were divided into two groups according to whether having clinical symptoms, i.e., asymptomatic HCM group (n=17) and symptomatic HCM group (n=12). Thirty normal children were also enrolled in the normal control group. All subjects underwent echocardiography, and the torsion-and strain-related data of the whole and different myocardial segments in the cardiac sections of left ventricle were obtained by 2D-STI. Results: Left ventricular strain analysis showed that the left ventricular longitudinal strains of both HCM groups decreased significantly compared with the normal control group (P<0.05), while the radial and circumferential strains increased significantly (P<0.05). The maximum difference of peak time in different segments on six cardiac sections in the symptomatic HCM group was significantly higher than that in the normal control group (P=0.000), while the difference between the asymptomatic HCM group and the normal control group was not significant. Left ventricular torsion function analysis showed that the global peak twists of left ventricle and positive peaks of rotation velocity in both HCM groups were significantly higher compared with the normal control group (P<0.05), standardized times to peak were longer (P<0.05), and negative peaks of rotation velocity and the untwisting rates were lower (P<0.05). Conclusion: In the children with HCM, the left ventricular torsion function is enhanced and diastolic function is weakened. In the symptomatic children, the left ventricular systolic synchrony is poor.

OBJECTIVETo investigate expansion characteristics of two kinds of commercial investment (Cristo balite Micro II and Cristo Quick), and their effects on cast accuracy of a dental Ag-Pd casting alloy.

METHODSTwo kinds of investment were mixed at the ratio of 1:3. The setting and thermal expansion curves of the investment were recorded according to the requirements of ISO7490 and expansion rate calculated, respectively. Plate-like wax-patterns with pre-marked points were invested in casting rings (lined with ceramic fiber liners with thickness of 0.45 mm). Castwell M.C dental alloy were melted with gas flame and cast with a centrifugal casting machine. The differences between the castings and the wax patterns at corresponding points were calculated to represent the dimensional changes of the investment.

RESULTSThe setting, thermal and total expansion rates were 0.68, 1.18, 1.86 for Cristo balite Micro II, and 0.94, 1.03, 1.97 for Cristo Quick. The setting and thermal expansion rates were statistically significant between two kinds of investment (P < 0.05), while not for the total expansion rates (P > 0.05). Effect of different investment on the precision of castings was not statistically significant (P > 0.05).

CONCLUSIONWithin the scope of this study, gypsum-bonded investment with similar total expansion rates but different expansion characteristics has no effect on the casting precision of Ag-Pd dental alloys.
