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.

Objective To explore the possibility and effectiveness of minimally invasive osteotomy and cable osteosynthesis for the treatment of adolescent eubitus varus. Methods Eleven cases of adolescent cubitus varns(2 cases complicated with internal rotation of 10°)were treated with minimally invasive supracondylar wedged osteotomy to preserve the integrity of the contralateral codex and periosteum.Two screws were inserted above and below the fracture line.They were fixed with cable after the greenstick fracture and internal rotation were adjusted.Plastic bandage was applied for 1 week postoperatively before rehabilitation. Results Bone fractures healed in the 11 cases in 36.3 days averagely,without infection or nerve palsy.Before operation,the mean angles of varus,flexion and extension were 35°±5°,125°±10°and 10°±5°respectively.After a mean follow-up of 33.5 months,the mean valgus angle of the elbow was improved to 8°±2°(t=16.632,P<0.05),flexion to 130°±8°and extension to 8°±3°(P>0.05).Internal rotation deformity was also ameliorated in the 2 cases. Conclusion It is practical and effective to treat adolescent eubitus varus with minimally invasive osteotomy and cable osteosynthesis,for it can lead to stable fixation,short healing time,and does not affect the flexion and extension of the elbow joint.

Objective To investigate the diagnosis and treatment of splenic space occupying lesions associated with comorbidity.Methods The clinical data of 5 patients from Jiangyin People' s Hospital and 9 patients from Wuxi People's Hospital from January 2002 to June 2012 were retrospectively analyzed.All the patients suffered from splenic space occupying lesions associated with comorbidity.Splenectomy or multi-visceral resection were selected according to the results of preoperative B sonography and computed tomography examination.Chemotherapy regimes were selected based on postoperative pathological examination.All the patients were followed up till June 2013.Results The symptoms of patients with splenic space occupying lesions were non-specific.The first symptoms of 4 patients were discomfort or distending pain of left upper abdomen,and the other 10patients had no symptoms.The coincidence rate of preoperative diagnosis was 10/14,and the coincidence rate of preoperative diagnosis for patients with malignant tumors was 2/5.Fourteen patients received preoperative B ultra-sonography,and 9 were definitively diagnosed.Nine patients received computed tomography,and 7 were definitively diagnosed.Of the 14 patients,right ovarian cancer,bilateral ovarian cancer and sigmoid colon cancer were correlated with solitary splenic metastasis,and the main lesions of the other 11 patients were not correlated with splenic space occupying lesions.The main lesions of patients with left colon carcinoma,type 2 diabetes and vascular tumor of the spleen,patients with renal carcinoma and splenic sclerosing hemangioma,and patients with hypertension,cholecystolithiasis and splenic lymphangioma were diagnosed simultaneously with the splenic space occupying lesions,and the main lesions of theother 11 patients were diagnosed separately with the splenic space occupying lesions.Ten patients underwent simple splenectomy and 4 patients received multi-visceral resection.Chemotherapy regimens were selected according to the type of main lesions for 5 patients who were diagnosed by pathological examinations.All the patients were recovered smoothly with no occurrence of severe infections.Two patients with splenic sarcoma had tumor metastasis at postoperative 6 months and 1 year,respectively.One patient with right ovarian cancer and solitary splenic metastasis had transverse colonic metastasis at postoperative 3 years.One patient with bilateral ovarian cancer and solitary splenic metastasis had peritoneal metastasis at postoperative 2 years.One patient with sigmoid colon cancer and solitary splenic metastasis died of peritoneal tumor recurrence at postoperative 4 years.One patient with left colon carcinoma,type 2diabetes and vascular tumor of the spleen survived for 6 years and was still sound and well.The other 9 patients with benign disease survived within the period of follow-up.Conclusions The definitive diagnosis for patients with splenic space occupying disease associated with comorbidity depends on the preoperative imaging examination and postoperative pathological examination.Surgical treatment is safe when operative contraindications are excluded.The prognosis of patients is determined by the progress of main lesions and the character of splenic space occupying lesions.

ObjectiveEvidence-based medicine was used to make an individualized treatment plan for rare solitary splenic metastasis of an ovarian carcinoma in a female patient. MethodsAfter clinical problems were discovered, evidence was collected from the Cochrane Library, PubMed, EMBASE, ScienceDirect, CNKI and Wanfang databases according to our predefined search strategy. The search was done until October, 2009. The validity of the evidence was assessed. The evidence, combined with the doctor experience and the patient value, was applied to the patient. ResultsA total of 15 English literature and 11 Chinese literature were identified. A rational treatment plan was made upon a critical evaluation of the data. There were 5 review articles in PubMed, EMBASE and ScienceDirect databases and no RCT in the Cochrane Library. And there was one retrospective cohort study inCNKI and Wanfang databases. The others were all case reports. After 20 month follow-up, the treatment protocol was proven correct. Conclusion The patient has rare disease, and the evidence intension for the evidence-based medicine was low. It can not present the efficacy of the evidence-based medicine treatment sufficiently, though it could provide some suggestion for rare disease which was lack of large RCT for evidence-based Methods .

Objective To observe the effect of DPC4 gene transfection on the chemotherapy sensitivity of pancreatic carcinoma cells. Methods The human DPC4 complementary DNA was subcloned to the retroviral vector pLXSN to obtain recombinant pLXSN/DPC4 with direct inserting potential. The daughter cell BxPC-3/DPC4 which had DPC4 stable expression was acquired after the pancreatic carcinoma BxPC-3 cells had been transfected with pLXSN/DPC4. The sensitivity of the carcinoma cells for 5-Fu and gemcitabine was observed. Meanwhile, the mRNA level of Mdr-1 and Chk1was detected by semi-quantity PCR assay. Results The 50% inhibiting concentrations (IC50)of 5-Fuand gemcitabin4e for BxPC-3 (culturing for 72 h) were rather lower than those of BxPC-3/pLXSN and BxPC-3/-cells. Moreover, the semi-quantity PCR assay revealed that the mRNA level of Mdr-1 and Chk1 was down-regulated. These findings indicated that pLXSN/DPC4 vector, 5-Fu and gemcitabine could inhibit the growth of pancreatic cancer cells. The combined therapy with pLXSN/DPC4 vector and chemotherapeutic drugs could further inhibit the growth of cancer cells. Conclusion The DPC4 gene transfection could enhance the sensitivity of pancreatic cells to chemotherapy, which may be realized through the down-regulation of Mdr-1 and Chk1 gene expression.

Objective To explore the possibility of treating tibial osteomyelitis with transfer of a compound flap composed of the sural nerve fasciocutaneous flap and the lateral gastroenemius muscle.Methods We observed in cadaver specimens the anatomical structure of the sural nerve fasciocutaneous flap and the lateral gastrocnemius muscle to design a compound flap. Fifteen cases of tibia] osteomyelitis were treated with sinus excision and thorough debridement before the skin defect area was covered with a sural nerve compound flap whose muscle was stuffed into the tibia] channel. Plates were replaced with unilateral fixators in 3 cases of tibial nonunion. Results We observed 5 to 6 perforating branches of blood vessels between the sural nerve fascioeutaneous flap and the lateral gastroenemius muscle, indicating that the two can be harvested simultaneously in one compound flap. The transferred compound flaps survived in 15 cases. Tibial os-teomyelitis was completely cured in 14 cases, 1 case healed after second debridement, and 3 cases of tibial nonunion healed 6 months later after a second stage iliac bone graft. No recurrence was found after a mean follow-up of 18 (10 to 26) months. Conclusion A compound flap composed of the sural nerve fascio-cutaneous flap and the lateral gastrocnemius muscle can be used to treat tibia] osteomyelitis effectively.

BACKGROUND:Dorsal digital block refers to the commonly used anesthesia for adults in smal or moderate hand injury surgeries, but in recent years, modified transthecal digital block technique is gradualy respected, which is favored with a rapid and good effect and fewer complications.
OBJECTIVE:To evaluate the clinical anesthetic outcomes of modified transthecal digital block and traditional dorsal digital block technique for the treatment of hand injury of adults in emergency by a prospective randomized controled study.
METHODS:Totaly 60 adult patients with hand injury were enroled and divided into two groups of modified transthecal digital block and traditional dorsal digital block randomly. Blocks were performed by one single surgeon. The operation time, local anesthetic dose, onset time of anesthesia, duration of anesthesia, success rate of anesthesia, visual analogue scale scores and complications were recorded.
RESULTS AND CONCLUSION:The anesthesia effects in the two groups were acceptable. There was no significant difference in the onset time of anesthesia, duration of anesthesia, success rate of anesthesia and complications between the two groups (P > 0.05). The operation time of anesthesia, local anesthetic dose, and visual analogue scale scores were significantly different between the two groups (P< 0.05). Modified transthecal digital block is more convenient and has less pain than the traditional root digital block, which is a safe and reliable anesthetic technique.
