Qualitative research methods are becoming more and more important in medical research area. Some qualitative researches played important roles in the exploration and the spread of core ideas of Chinese medicine. The report of qualitative research should be transparent and credible according to the standardized report criterion. On the basis of 22 criteria, the Consolidated Criteria for Reporting Qualitative Research (COREQ) was developed and published in September 2007. This introduction to COREQ will be helpful to Chinese qualitative researchers and readers in the implementation of high quality of medical qualitative research in China.

BACKGROUND:Tissue engineering provides new ideas and approaches for repair of cartilage defects.
OBJECTIVE:To develop a complete set of solutions for construction of tissue engineered cartilagein vitro, with chondrocytes as seed cels and cross-linked sodium hyaluronate as scaffold materials.
METHODS: New Zealand rabbit articular chondrocytes were isolated, counted, and then cultured and passaged to prepare cellsuspension. Toluidine blue staining, RT-PCR and immunocytochemistry were exerted to evaluate the cultured cels. Chondrocytes were seeded and co-cultured with cross-linked sodium hyaluronate scaffold for 21 days. Then, RNA was isolated for RT-PCR, and frozen sections were prepared for morphological observation and immunohistochemistry study.
RESULTS AND CONCLUSION:The chondrocytes could adhere to the cross-linked sodium hyaluronate scaffold and aggregate, growing between fibers or adhering to the scaffold in a monolayer manner. The transcripts of cartilage specific aggrecan gene and colagen type II alpha 1 gene and cartilage specific protein colagen type II were expressed in cel-scaffold complexes to maintain the phenotype of chondrocytes. Cel-scaffold complexes co-cultured in vitro can form cartilage extracelular matrix, by which tissue engineered cartilage is expected to be obtained.

OBJECTIVETo explore the effective method of the prevention and treatment of procedural pain in dressing changes of burn wounds.

METHODSNinety patients of burn injury were randomized into 3 groups, 30 cases in each one. In the group A, fentanyl citrate injection was used at corresponding injury area, jiaogan (AH6a, sympathetic nerve), fei (CO14, lung), neifenmi (CO18, endocrine) on ear, 0.25 mL at each point. In the group B, fentanyl citrate injection was applied subcutaneously in the deltoid muscle, 1 mL. In the group C, 0.9% sodium chloride injection was applied subcutaneously in the deltoid muscle, 1 mL. The visual analogue scale (VAS) was used to evaluate the analgesic effect before, during and 10 min after dressing change in the patients of the three groups separately.

RESULTSIt was not different in VAS score before dressing change among the three groups (P> 0.05). Compared with that before dressing change, the pain was not significant and VAS score was not different during and after dressing change in the patients of the group A (both P>0.05), but the score in the patients of the group B and C was different significantly (all P<0.05). The VAS score during and after dressing change in the group A was lower than that in the group B and C (all P<0.05), and the score in the group B was lower than that in the group C (P<0.05).

CONCLUSIONFentanyl injection of small dose at auricular points achieves definite analgesic effect on procedural pain in dressing changes of burn wounds, superior to subcutaneous injection of fentanyl.

Objective:To explore the clinical value of remote ECG consultation for primary medical institutions. Methods:Remote ECG consultation data for medical institutions of different levels in Hubei Jianli county were sta-tistically analyzed.Results:In county hospitals of this area,there were 1334 cases of ECG consultation,the positive rate was 41.00% (547/1334),and the three abnormal ECG types with highest incidence rate were arrhythmia (27.29%),left ventricular hypertrophy (LVH,9.15%)and ST-T change (2.62%)in order;in rural health rooms of this area,there were 723 cases of ECG consultation,the positive rate was 55.19%(399/723),and the three ab-normal ECG types with highest incidence rate were arrhythmia (34.02%),ST-T change (11.07%)and LVH (5.39%)in order.Conclusion:The remote ECG consultation is easy to perform.It can rise the detection rate of transient abnormal ECG events in rural area,where is lack of ECG equipment and personnel,so it is worthy of ex-tending.

Objective To analyze current situation and problems of health manager training in the pilot training areas. Method With the recommendations of health administration deputies in the plot areas of Shanghai, Chongqing and Urumqi, 2 centers for community health services (CHSs) were selected in each area, 9 relative persons were interviewed, 3 focus group discussions (FGDs) involved 18 persons were held totally. The FGDs focused on such questions as“the general information of the training students”“the objectives and purposes of the training in each area”, and so on. Field investigation and qualitative analysis were used to investigate the status quo and main problems of the training of health manager in the pilot areas. Result The problems of the training of health manager existing in the pilot areas mainly are:part of teachers were not fully competent to the training of health manager, training of operant skill was insufficient, training course was not unified, the assessment mechanism was not perfect. Conclusion Optimizing the construction of teachers team, standardizing the training content, increasing the time of operating skills training, establishing a unified and standardized assessment mechanism are essential.

AIM: To discuss the effects of phytoestrogenic-genistein on cathepsin K (CK) expression stimulated by interleukin-1α (IL-1α) in osteoclast-like cells (OCLs) . METHODS: The OCLs were isolated from tissue of human giant cell tumor of bone (GCT) . The cells treated with reagents were divided into 7 groups including control (treated with phenol red-free-DMEM), vehicle (treated with 1.2 nmol· L-1 IL- 1α), 10-10-10-6genistein, genistein+ ICI 182.780, and 17[β-estrodiol (17β-E2) group. The cells were treated with 1.2 nmol· L-1IL-1α after pre-treated with genistein or 17β-E2 for 48 h (excluded the control group) . Expression of CK wasdetermined by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot in OCLs stimulated by IL-1α in the presence of genistein or 17[β-E2. RESULTS: The obvious increase of expression of CK by IL1α in vehicle group was noted in comparing with control group (P ＜ 0.01 ) . Genistein down-regulated CK gene expression stimulated by IL-1α at the transcription level in a dose-dependent manner (r = 0.68, P ＜ 0.01 ) .Genistein down-regulated CK protein expression stimulated by IL-1α also in a dose-dependent manner (r = 0.61,P ＜ 0.01 ). The effects of genistein were abrogated partly after treatment with the estrogen receptor antagonist ICI 182.780. CONCLUSION: Genistein inhibits CK expression stimulated by IL-1α partly through estrogen receptor in OCLs.

Objective To observe the apeptosis in liver injury following limbs ischemia-reperfusion(IR) in rats and the protective effects of taurine.Methods The model of limbs ischemia-reperfusion injury was established.30 Wistar rats were randomized into 3 groups: control group,IR group and tanrine + reperfusion group (TR group) (n = 10 for each group).The levels of malondialdehyde (MDA) and xanthineoxidas (XOD), calcium and myeloper-oxidase (MPO) in the liver tissue were measured.DNA fragmentation was observed and analyzed by agarose gel e-lectrophoresis.Apoptosis was detected by TUNEL methods.The morphologic changes were observed with HE stai-ning.Results Compared with control group,the values of MDA, XOD, MPO, calcium in liver tissue were increased significantly in IR group (P<0.01), but the values of those in TR group were lower than in IR group (P<0.01).The percentage of apeptosis cell was higher in IR group than in control group(P<0.01).Compared with IR group, the percentage of apoptosis cell was lower in TR group (P<0.01).IR group presented DNA ladder pattern, while TR group showed no specific DNA ladder pattern in agarose gel electrophoresis.Conclusion Apoptosis participates in the liver injury after limb ischemia-reperfusion.Taurine can mitigate the liver injury and apoptosis after limb is-chemia-reperfusion injury in rats.

OBJECTIVETo search for an optimum method for testicular prothesis implantation in the treatment of testis loss.

METHODSWe retrospectively analyzed the surgical methods and outcomes of 53 cases of terminal prostate cancer and 4 cases of unilateral testicular torsion treated by implantation of testicular prothesis with the polypropylene mesh.

RESULTSThe 57 male patients all received testicular prothesis with the polypropylene mesh. All the patients were satisfied with the appearance and size of the scrotum after surgery. No scrotal hematoma, prosthesis infection, or autoimmune disease occurred postoperatively.

CONCLUSIONTestis loss is not a rare condition clinically, for the treatment of which surgical implantation of testicular prothesis with the polypropylene mesh can achieve both a fine tissue compatibility and a desirable scrotal appearance.
