Objective:To explore the clinical outcomes of anatomical double-bundle medial patellofemoral ligament (MPFL) reconstruction with double suture anchor technique in treating patellofemoral instability in adolescent.Methods:Twenty-five young people with patellofemoral instability (25 knees) in our department from January 2013 to December 2014 were enrolled for this study.All patients were performed anatomical double-bundle MPFL reconstruction with arthroscopic-assisted suture anchors technique in the patella,and fixed in the femoral socket with absorbable interference screw.All patients are evaluated by different methods,including patient's satisfaction,patellar apprehension test,recurrent subluxation/dislocation,CT assessment of bone tunnel and patellar tilt angle.Lysholm scores,Tegner scores and Kujala scores were recorded at the final follow-up.Results:The mean follow-up was 24 (range 20-40) months.All cases were observed in negative patellar apprehension test.Infection,recurrent subluxation/dislocation and patellar fracture were not found at the last follow-up.CT results demonstrated that the tunnel position were good.The patellar tilt angle was decreased from 21.6°±2.3° to 10.5°±1.6° (P<0.05);the Lysholm scores was increased from 51.7±5.3 to 93.8±6.5 (P<0.05).Tegner scores was increased from 4.1± 1.1 to 5.5±0.6 (P<0.05).Kujala scores was increased from 53.5±6.4 to 94.6±4.3 (P<0.05).Conclusion:Arthroscopic-assisted anatomical double-bundle MPFL reconstruction with the suture anchors technique is a safe,minimal invasive and effective surgical option for treating patellofemoral instability in adolescent.

BACKGROUND:The mechanical index is an important method for the evaluation of the therapeutic efficiency of drug treatment for osteoporosis animal models. OBJECTIVE: To explore the effects of various drug treatments on osteoporosis through a mechanical performance test about the femoral compression of rats. METHODS: Thirty-six Wistar female rats were randomized into six groups: normal control group, model group, Dan Qiparticles group, alpha-D3 group, premarin group, ipriflavone group, with six rats in each group. Osteoporosis models were made in al groups except for the normal control group, and after modeling, the rats in different groups were treated withDan Qi particles, alpha-D3 group, premarin and ipriflavone, respectively. After 15 weeks, the rats were kiled by abdominal aortic bloodletting to take out the left and right femurs that were placed on a universal testing machine to perform a compressive test at a speed of 5 mm/min. RESULTS AND CONCLUSION:The maximum load, maximum stress, maximum displacement, maximum strain, and elastic modulus were significantly lower in the model group than the other four groups (P < 0.05). There was no difference in different mechanical parameters between alpha-D3 group and model group as wel as between Dan Qi particles group and normal control group (P> 0.05). These findings indicate that osteoporosis leads to the variation of compression mechanical properties of the femur. There are good compression mechanical properties of the femur after treatment with premarin and ipriflavone, andDan Qi particles has the best effect.

Pain is one of the common clinical symptom, previous studies have implicated sodium channels as a key constituent in pain signaling. Sodium channel blockers with efficient sodium channel blockade effect play an important role in analgesic treatment. However, most drugs used in clinic have many drawbacks and can not meet the demand of the clinical use. Therefore, for the development of new generation of sodium channel blockers, it is of great significance to find small molecule sodium channel blocking lead compounds with novel chemical scaffolds and new structures, sodium channel blocking activity and structure-activity relationship are discussed in detail, and current problems and trends in future research are also emphasized.

Objective To investigate the clinical efficacy ofHejie Fenxiao Decoction on damp-heat patients with acute kidney injury (AKI).Methods Totally 68 patients were divided into the control group and the treatment group according to the patients’ willings. Both groups were given treatment, such as elimination of the incentives and symptomatic treatment. Besides, patients of the treatment group acceptedHejie Fenxiao Decoction for 30 days. The changes of renal function indexes, such as serum creatinine (SCr), blood urine nitrogen (BUN), uric acid (UA), albumin (ALB) and integral of TCM syndrome, were observed, and recovery ratio and clinical endpoints were compared.Results SCr and eGFR of both group were improved on day 14 (P<0.05). After treatment, the renal function recovery ratio and renal replacement ratio in the two groups showed obvious differences (P<0.05);although survival rate of treatment group was higher than control group, it showed no statistical significance (P>0.05);clinical endpoints analysis of the two groups showed statistical significance (P<0.05). The difference of integrals of TCM syndrome between the two groups showed statistical significance (P<0.05) on day 14.ConclusionHejie Fenxiao Decoction combined with basic regular Western medicine can better improve the clinical symptom, recover the renal function, and decrease the rate of renal replacement and death of AKI damp-heat patients.

Streptomyces sp. A048 was cultured in a complete medium to the last stage of log phase,the hyphae were washed and collected by centrifugation. Then the hyphae were inoculated in liquid medium for chitinase production using two-step fermentation. Activity of chitinase produced by two-step fermentation was 1.1 times higher than that from one-step fermentation,and ferment cycle was for 54 hours,which was 66 hours shorter than that of one-step fermentation. The hyphae and the powder of chitin were co-immobilizated and cultured in liquid medium for 36 hours,activity of chitinase was 1.8 times higher than that from one-step fermentation,and ferment cycle was 54h shorter than that of one-step fermentation. By adding 0.4% cellulose to two-step fermentation,activity of chitinase was 18.52 U/mL that was 4 times higher than that from the control and 10 times higher than that from one-step fermentation. Two step fermentation with chitin and cellulose may be the optimal fermentation process to produce Chitinase from Streptomyces sp. A048.

Heterokaryon incompatibility is a widespread phenomenon among fungi,controlled by specific loci termed het (for heterokaryon incompatibility).This review focuses on recent developments in our understanding of the molecular mechanisms of nonself recognition and the relationship between the death progresses of heterokaryon incompatibility and associated proteins in fungi.The deep research of heterokaryon incompatibility mechanism will hopefully reveal underlying principles of the evolution of nonself recognition systems and will find some effective method for settling the instability of protoplast fusant of fungi.
