To summarize the accumulated successful experiences, defeated cases and lessons the recent year’s clinical studies, works and experiences of hip prosthesis combining the relevant status abroad and to analyze some questions such as the operations are not standardized; the indications are not strict; overemphasizing the navigation and mini-invasion; clinical techniques are irregular, and the patients should be educated, and so on. The above questions influence the good development of the Chinese joint prosthesis and reduce the clinical outcomes of the joint prosthesis. Taken together, these questions should be concerned and resolved. Relevant solutions are discussed.

In order to investigate the application of standard score in the examination of eight-year program's clinical practice and to keep consistency of learning level among groups, we translate the original scores into standard scores and discuss the results and how to define the excellent grade so that the scores may have more comparability.

BACKGROUND: Facial nerve injury causes facial nerve paralysis (or facial palsy) and even results in psychosocial disturbances of the patients. Repair the injured facial nerve and reconstruction of the nerve function as early as possible have been the primary concern in clinical studies.OBJECTIVE: To investigate the timing and surgical approaches for repairing facial paralysis in order to provides evidences for its therapeutic and prognostic evaluation.DESIGN: Case analysis based on patients.SETTING: Hospital of Plastic Surgery of Chinese Academy of Medical Sciences.PARTICIPANTS: Nine patients with traumatic facial paralysis hospitalized in the Hospital of Plastic Surgery of Chinese Academy of Medical Sciences from December 1993 to November 2001.METHODS: Facial nerve anastomosis was performed microsurgically along with the implantation of the sural nerve graft into orbicular muscle of the eye 3 or 4 months after nerve injury in the 9 patients. The clinical data of the patients were retrospectively reviewed.MAIN OUTCOME MEASURES: The facial nerve function was evaluated with House-Brackmann scale and photographs of the patients' faces before and after surgical treatment were taken.RESULTS: In the follow-up of these patients lasting 6 months to 2 years,all the patients attained satisfactory outcome.CONCLUSION: Early operation is crucial for the treatment of traumatic facial paralysis,with facial nerve anastomosis as the primary choice. The implantation of the nerve graft into muscle is also indicated for repairing traumatic facial paralysis in some cases. The importance of individualized treatment choice is reiterated on the basis of cicatrectomy and the extent and specific features of the injury.

Objective. To study the performance of free nerve graft with vascular implantation.Material and method. Three groups of rats were used. A 10 mm nerve defect was made in the sciatic nerve. It was repaired respectively with vascularised nerve graft(VNG), free nerve graft with vascular implantation(NGV) or free nerve graft(NG). Before 30 days the revascularisation of the nerve graft was assessed;at 2 to 3 month regeneration of nerve was evaluated. Histochemical staining, vascular morphology and electrophysiological examination were undertaken.Result and conclusion. The number of regenerated blood vessels in VNG and NGV was significantly increased than that in NG before 30 days. The ratio of regenerated nerve fiber area and conduction velocity in the first two groups were much better than those in NG at 2 to 3 months.

Objective To analyze the risk factors of BKV infection and compare the real-time PCR procedure and urinary sediment smears of patients checked for decoy cells. Methods The peripheral blood samples of 129 renal recipients were collected. According to the result of PCR, 129 patients were divided into 2 groups:①BKV-DNA(+);②BKV-DNA(-). The sex, age, cold ischemia time, hemotodialysis duration, immunosuppressive agent and other clinical parameters were compared between the 2 groups and a Logistic regression was performed to analyze the risk factors of BKV infection. Results There were 20(15. 5%) patients in BKV-DNA(+), 109(84. 5%)patients in BKV-DNA(-)group. Logistic regression found that the cold ischemia time, hematodialysis duration, living donor were significantly related to the BKV-DNA. The results of the real-time PCR procedure and urinary sediment smears of patients checked for decoy cells were related. Conclusion Real-time fluorescent quantitative PCR and urine decoy cell are good way for detection of BKV infection after renal transplantation. The cold ischemia time and hematodialysis duration and brain death donor were the risk factors of BKV infection post renal transplantation.

OBJECTIVEOn the basis of the concept of adhesive deformity from upper eyelid fold formation, the clinical results after using various methods to correct the adhesive deformities are summarized.

METHODSA total of 33 cases of adhesive deformity from upper eyelid fold formation have been treated using various corrective methods including taking off the sutures, shifting of the septal fat or the pre-septal orbicularis muscle, transferring of pretarsal orbicularis muscle, grafting of autogenous fat tissue, and repairing or/and shortening of the palpebral levator. Postoperative follow-up ranged from 3 months to 2 years.

RESULTSThe effective results have been got with the used methods except shifting of the pre-septal orbicularis muscle or transferring of pretarsal orbicularis muscle.

CONCLUSIONSThe suitable methods to correct the adhesive deformity from upper eyelid fold formation must be chosen according to the causes and the local situations.

OBJECTIVETo study the relation between the expression of transcription factor T-bet/GATA3 and Th1/Th2 type cytokines in peripheral blood mononuclear cells (PBMC) from lung cancer patients and their interference by the traditional Chinese herbal medicine.

METHODSThe gene expression of Th1/Th2 type cytokine IFN gamma, IL-2, IL-4, IL-6, IL-10, transcription factor T-bet/GATA3 and tumor tissue specific mRNA CEA, CK19 in PBMC from lung cancer patients were detected by reverse transcription-polymerase chain reaction RT-PCR. Meanwhile, the change of IFN gamma, IL-4, T-bet and GATA3 in PBMC before and after being cultured with the traditional Chinese herbal medicine-Astragulus and Tetramethylpyrazine was also observed.

RESULTSPredominant expression of Th2 type cytokines was detected in 42 lung cancer patients. The positive rates of IL-4, IL-6, IL-10, IFN gamma and IL-2 were 27/42, 24/42, 31/42, 4/42 and 5/42, respectively. But, the positive rates of transcription factor T-bet and GATA3 were 16/42 and 34/42. Moreover, the expression intensity of T-bet was lower in the CEA and CK19 positive patients than the negative ones. On the contrary, the expression intensity of GATA3 was significantly higher in the same patients.

CONCLUSIONPredominant expression of Th2 type cytokines may be related to lower expression of T-bet or higher expression of GATA3. This condition can be interfered by the traditional Chinese herbal medicine-Astragulus and Tetramethylpyrazine.
