Progress in the metacarpophalangealgeal joint implantation has drawn increasing attention to its role in treatment of chronic arthritis of the hand. This paper summarizes the biomechanic research and devolvement of the prosthesis, preoperative evaluation and plan for metacarpophalangealgeal joint implantation and the clinical results of different designs of the MCP prosthetic joint in the past decade. With improvement of prosthesis designs and operative technology, the MCP implantation will play a better role in clinical treatment of chronic arthritis of the hand, such as relief of pain, rectification of abnormality and functional recovery of the hand.

Objective To explore the effect of Jiangzhipailuan decoction in regulating PPARα( belong to the nuclear receptor family of ligand-activated transcription factors ), PGC- 1α ( peroxime proliferator activated releptour)and SREBP-1c( belong to the baichelix-loop-helix-leucine zipper class of transcription factors), SCAP( SREBP cleavage activating protein) related to lipid metabolism in the treatment of polycystic ovarian syndrome. Methods 84 patients suffered polycystic ovary syndrome were randomly divided into 4 groups: one received traditional Chinese medicine treatment, one western medicine treatment, one combination therapy and one as the control group. Traditional Chinese medicine group was treated with Jiangzhipailuan decoction treatment for 3 months, western medicine group was treated with up to Diane-35 ( ethinyl cyproterone tablets) for three cycles, while the combination therapy group was treated with traditional Chinese medicine ,western medicine as well as combined treatment for 3 courses. Results In the combination therapy group the PPARα, PGC-1α and decreased SREBP-1c, SCAP copy number was significantly improved ,and body mass index was significantly lowered. The total improvement rate of menstrual in three groups were 71.42% ,75.00% ,92.86% respectively. Conclusion Jiangzhipailuan decoction played a prominent role in regulating PPARα,PGC-1α and SREBP-1c,SCAP related to lipid metabolism in the treatment of polycystic ovarian syndrome.

BACKGROUND: The articular surface of interphalangeal joint and metacarpophalangeal joint is destroyed or defected, that would remain serious sequela in many patients and affect patient's routine work and living. Therefore, therapeutic efficacy of finger joint damage determines the functional recovery of hands. Tissue engineering provides a novel pathway for finger joint damage. OBJECTIVE: To summarize the research progress on the repair and reconstruction of finger joint damage. RETRIEVAL STRATEGY: The researcher of this article used the computer to retrieve literatures of Pubmed database with docuterms of "Interphalangeal joints fractures, Metacarpophalangeal joints fractures, Finger osteoarticular, Reconstruct", and the language was defined to English. Meanwhile China Academic Journals Full-Text Database from 2000 to 2007 was also retrieved with docuterms of "Interphalangeal joints, Metacarpophalangeal joints, Fractures, Repair and reconstruct", and the language was defined to Chinese. Totally 106 correlated articles were screened out and the data were firstly checked. Inclusion standard: ①closely correlated to the repair and reconstruction of finger joint damage; ②those published in the near future or authorized journal in the same field were preferred. Exclusion standard: repetitive investigation. LITERATURE EVALUATION: The resource of literatures was the clinic empirical studies of the repair and reconstruction of finger joint damage. Among 32 included articles, 3 of them were reviews and the others were clinic or empirical studies. DATA SYNTHESIS: The homogeneity variant bone-joint transplantation has got some successes in clinic, but how to prolong the survival time of transplanting joints would be a new research topic. Autoallergic joint transplantation is a good method to treat the defects of finger joints, but how to make handling conveniently, diminish secondary damage and search new donor site, all deserve to research. The ideal therapeutic efficacy of the finger joint damage is anatomical reset of the joint profile, that can reduce traumatic arthritis and anchylosis at the minimal level. But it is still a tough problem in the fingers joint's repairs, because of the multiple structure of bone-joint in hands and trauma factors. Open reduction and internal fixation, skeletal traction, arthroplasty, fusion of joint, prosthetic replacement of joint, articular transplantation and bone-joint tissue engineering have all obtained success, but none can fully succeed or be generally adopted. CONCLUSION: There are many treatments of the finger joint damage, but their results are not very well. With the research of homogeneity variant bone-joint transplantation, autoallergic joint transplantation and tissue engineering development, bone-joint transplantation will have a wide prospect in treatment of finger joints damage.

0.01). CONCLUSION: The 5th CMC joint of the hamatum can be considered to be a new and well joint donor site, and it can be used to repair and reconstruct the base joints of the proximal phalanx.

Objective: To explore the characteristics of clinical pathology, diagnosis, and prognosis of primary renal lymphoma (PRL).Methods: The clinical features, pathological features, immune phenotypes, treatment, and prognosis of 22 patients were retrospectively analyzed. Results: The PRL patients' ages ranged from 2 to 72 years (mean, 54.3 years), of which 13 patients were older than 50 years (59.1%). All of the 22 patients were diagnosed with non-Hodgkin's lymphoma (NHL), including 20 cases of B-cell lymphoma and 2 cases of T-cell lymphoma. Seven patients were still alive and survived for 6-50 months, but the other 15 were dead and survived for only 5-35 months. Conclusion: PRL is uncommon. Clinical manifestations and imaging performance specificity are not obvious. and easily misdiagnosed. Histopathology is still the golden standard for the final diagnosis of this entity. The kidney is most easily involved followed by the bladder. B-cell NHL is the common subtype, and the most common type is the diffuse large B-cell lymphoma. Up to now,no standard regime could be performed for PRL patients. At present, comprehensive therapy, including surgery and chemotherapy, is recommended. For patients with locally advanced or highly aggressive status, therapeutic effect with chemotherapy alone is usually satisfied.

Objective:To evaluate the diagnostic efficiency of hypersensitivity quantitative fecal immunochemical test (hs-qFIT) in colorectal cancer (CRC) and advanced adenoma.Methods:From July to December 2020, consecutive patients aged 50 to 75 years who underwent colonoscopy in Qilu Hospital of Shandong University, and had the Asia-Pacific colorectal screening score of medium or high risk were enrolled. All patients were requested to complete two hs-qFIT before colonoscopy. The diagnostic efficacy of hs-qFIT for CRC and advanced adenoma were assessed. Receiver operating characteristic curve of hs-qFIT in CRC diagnosis was drawn and the area under the curve (AUC) was calculated.Results:A total of 811 patients including 20 (2.5%) cases of CRC, 47 (5.8%) cases of advanced adenoma, 206 (25.4%) cases of non-advanced adenoma, 219 (27.0%) cases of non-adenomatous polyp, 76 (9.4%) cases of other colorectal lesions and 243 (30.0%) cases of non-colorectal lesions were involved. When the fecal hemoglobin cut-off values were 10, 30, 50, 75 and 100 ng/mL, the positive rates of hs-qFIT detection were 17.9% (145/811), 10.9% (88/811), 8.3% (67/811), 7.4% (60/811) and 5.8% (47/811), respectively. When the cut-off value of fecal hemoglobin decreased from 100 ng/mL to 10 ng/mL, the sensitivity of hs-qFIT for CRC diagnosis increased from 90.0% to 100.0%, and the specificity decreased from 96.3% to 84.2%; and the sensitivity of hs-qFIT for the diagnosis of advanced adenoma increased from 19.1% to 66.0%, and the specificity decreased from 95.0% to 85.1%. The AUC of hs-qFIT for the diagnosis of CRC and advanced adenoma were 0.981 (95% confidence interval ( CI) 0.970 to 0.992) and 0.846 (95% CI 0.807 to 0.886), respectively. When the optimal cut-off values were taken, the sensitivity and specificity were 100.0% and 91.2% for the diagnosis of CRC, and 66.0% and 85.3% for the diagnosis of advanced adenoma, respectively. Conclusion:Hs-qFIT can help the early screening of CRC and advanced adenoma.
