BACKGROUND:It has been an urgent problem of how to promote cartilage repair of the knee and shorten the total course through a tissue engineering approach. Fortunately, microfracture plus stem cel transplantation may open up a new path for this issue. OBJECTIVE:To investigate the clinic feasibility of arthroscopic microfracture technique plus stem cel transplantation for repair of articular cartilage injury of the knee. METHODS:From October 2010 to March 2012, a total of 16 patients with articular cartilage injury of the knee were enrol ed, including 12 males and 4 females, with the average age of 38.6 years (16-52). Al cases of cartilage injury were confirmed by arthroscopy. Autologous bone marrow was extracted from patients at 2 weeks before treatment to isolate, culture and amplify bone marrow mesenchymal stem cel s in vitro. The cel culture solution of 3-5 mL (about 107 cel s) was harvested. The articular cavity was clean by arthroscopy and microfracture technique was performed at the area of cartilage injury that was then covered with hemostatic gauze through a minimal y invasive incision and the prepared bone marrow mesenchymal stem cel s were injected. The knee was bandaged with the elastic bandage after aspirating the joint cavity effusion by vacuum suction. Functional exercises were performed early by CPM.RESULTS AND CONCLUSION:After fol ow-up of 4-18 months, there were 13 cases of excel ent, 2 cases of valid and 1 case of ineffective. According to Lysholm knee scores, the average scores were improved from 42 points (33-67 points) to 89 points (75-99 points) at 4 weeks after treatment. The function was satisfied and al patients were fol owed up without recurrence or worse. Under the arthroscopy, the combination of microfracture technique and autologous bone marrow mesenchymal stem cel transplantation is proved to be effective for articular cartilage injury of the knee and it can notably improve the clinic symptoms and recover the function of the knee.

Objective To explore the clinical significance of the precision evaluation of computed tomography angiography and color Doppler image formation technology to the condition of the vascular system in the donor site.Methods From January,2014 to December,2014,CTA and color Doppler were used to examine conditions of the first dorsal metatarsal artery's courser and the size of original caliber in 25 patients with thumb or finger defected.Also the distance between skin and the first dorsal metatarsal artery.The accurate positions and adjacent relations of vessels in donor site were precisely marked and then the vessel original caliber was measured.Results All the first dorsal metatarsal arteries of 25 cases can be appeared clearly in CTA and color Doppler.Blood vessels line and filling results were completely consistent in intraoperative findings.The difference of the vessel original average caliber was statistically significant (P ＜ 0.05) (1.20 ± 0.25 mm,1.41 ± 0.15 mm and 1.3 ±0.2 mm in Doppler,CTA and operation,respectively) while the distance was not significant (P ＞ 0.05)(9.20 ±3.06 mm,10.32 ± 2.76 mm and 0.2 ± 2.6 mm in Doppler,CTA and operation,respectively) All the 25 transplanted toes were survived.Conclusion CTA combined color Doppler image formation technology in thumb or finger reconstruction can objectively reflect the real situation of the vessels in donor sites,and the structural characteristics and classification of anatomy for individualized,and has important clinical value in preoperative foot blood supply assessment.

Objective To research the clinical manifestations of renal tuberculosis and improve the diagnosis and treatment of renal tuberculosis. Methods From 1993 to 2007,223 cases of renal tuberculosis were hospitalized. Retrospective analysis was complied for all the cases about age, clinical manifestations, imaging and treatment. Results The incidence rates of the renal tuberculosis were obviously higher in the 20-40 years old(41.7%) and in the 41-54 years old (36.3%). The course of this disease was from 1 day to 30 years(mean 38. 5 months). Only 36 patients (16.1%) were made a definite diagnosis when they went to see a doctor primary. The miediagnosis of urinary tract infec-tions( 50.3%) was most frequent. The clinical manifestations of most patients included frequency(54.7%), urgency(50.2%), odynuria(42.2%)and hematuria(58.7%). About 58. 3% patients pres-ented with over 3 kinds of above manifestations. The positive yield of the tuberculin test in urine was only 41.9%. The positive diagnostic rate of renal tuberculosis was only 35.7% in KUB+IVU,72.2%in Type-B Ultrasonic, 76.0% in CT test. One hundred and seventy-three cases were performed with nephrectomy(78.6%) and partial nephrectomy(21.4%). Two cases were treated with dialysis due to uremia. Standard medication was taken for the other 48 patiernts, and effective for 41 cases. Conclu-sions The incidence of atypical renal tuberculosis is increasing. More attention must be paid especially to those patients with urinary infection.

BACKGROUND:Carboxymethyl chitosan (CMCS),a chitin derivative,has a good application performance that makes it become a safe and effective hemostatic material.OBJECTIVE:To determine the hemostatic effect of CMCS and its biosecurity properties.METHODS:(1) CMCS powder was scattered on the caudal vein and liver wounds of Sprague-Dawley rats,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(2) CMCS powder was scattered on the tail,femoral artery and liver wounds of ICR mice,and the hemostatic time was recorded as experimental group,while the time for natural haemostasis of the wound was recorded as control group.(3) CMCS,Sodium dodecyl sulfate solution and distilled water were respectively applied on the skin of albino rabbits in a skin irritation test.(4) A delayed-type hypersensitivity test of CMCS was carried out by intradermal injection of CMCS in guinea pigs.(5) An intradermal irritation test was carried out by subcutaneous injection of normal saline containing CMCS and normal saline,respectively.Another intradermal irritation test was carried out by subcutaneous injection of the supernatant of CMCS olive oil extract and olive oil,respectively.RESULTS AND CONCLUSION:(1) Compared with the control group,the hemostatic time for caudal vein and liver wounds were significantly shortened in the Sprague-Dawley rats in the experimental group (P ＜ 0.01).(2) Compared with the control group,the time of hemostasis on the tail,femoral artery and liver wounds was significantly shortened in the ICR mice in the experimental group (P ＜ 0.05 or P ＜ 0.01).(3) The CMCS had no irritation to the skin of albino rabbits and no allergic reaction to the skin of guinea pigs.To conclude,the CMCS has good hemostatic effect on the wound in Sprague-Dawley rats and ICR mice,and has no skin irritation,allergic reactions and intradermal irritation reactions in albino rabbits and guinea pigs,which is a relatively safe hemostatic material.

Objective To investigate the regulatory effects of Zishen Yutai Pills on the expression levels of homeboxA10 (HOXA10) and its downstream target gene empty spiracles homebox 2 (EMX2) in the endometria of ovulation-inducing mice at different implantation stages. Methods Seventy-five estrous female Kunming mice were randomly divided into 5 groups, namely normal group, model group 1, model group 2, treatment group 1, treatment group 2, 15 mice in each group. The model group 1 was given short-term protocol for ovulation induction; the model group 2 was given long-term protocol for ovulation induction; the treatment group 1 was given Zishen Yutai pills (at the dose of 0.4 g/mL) on the basis of the protocol for the model group 1; the treatment group 2 was given Zishen Yutai Pills (at the dose of 0.4 g/mL) on the basis of the protocol for the model group 2; the normal group was given intragastric administration or intraperitoneal injection of the same volume of normal saline. The mRNA and protein expression levels of HOXA10 and EMX2 in mouse uterus were detected by real-time fluorescent quantitative polymerase chain reaction (qPCR) and Western blot method, respectively. Results Compared with the normal group, the mRNA and protein expression levels of HOXA10 were decreased, and the mRNA and protein expression levels of EMX2 were increased in model group 1 and model group 2(P< 0.01). Compared with the corresponding model group 1 and 2, the mRNA and protein expression levels of HOXA10 were significantly up-regulated (P < 0.01) , and the mRNA and protein expression levels of EMX2 were decreased in the treatment group 1 and 2 (P < 0.01), respectively. Conclusion Zishen Yutai Pills may improve mouse endometrial receptivity by up-regulating HOXA10 expression and inhibiting EMX2 expression.
