With the deepening of the reform of public hospitals at the county level,as well as the development of medical technology personnel training and medical technology development in county hospitals,county hospitals should be able to make use of the latest technology to undertake the common diseases and frequently occurring diseases of county residents.So at present,the teaching hospitals affiliated to medical universities should carry out the short-term training of the latest special techniques in the training of the regular doctors.Department of Urology of the first Affiliated Hospital of Chongqing Medical University,in the 3 month training cycle,with improving the self-learning ability of the refresher doctors as the core,carried out the hand by hand teaching of small classes and introducing model teaching,which achieved good results.

ObjectiveTo observe andanalyze the clinical efficacy of needle knife treatment for knee meniscus injury from improving knee biomechanical balance and to provide a therapeutic basis and method for clinical practice.MethodOne hundred patients (112 knees) with knee meniscus injury meeting the inclusion criteria were allocated, in order of visits, to observation and control groups, 50 cases each. They were treated with a needle knife and an injection of sodium hyaluronate injectio into knee joint cavity, respectively. Changes in the indices were observed and assessed in the two groups by recording the plantar pressure analysis score and the knee function score before and after treatment and at follow-up. The clinical therapeutic effects were evaluated in the two groups.ResultThemaximum load, time integral difference value and load ratio around the knee joint decreased significantly in both observation and control groups after treatment and at follow-up (P<0.05). The regulating effect on knee joint force balance was better in theneedle knife group than in the control group (P<0.05). The improving effect on knee joint function was significantly better in the observation group than in the control group (P<0.01). The excellence rate was significantly higher in the observation groupthan in the control group after treatment and at follow-up (P<0.05).ConclusionNeedle knife treatment restores the function of the knee joint by loosing focal soft tissues around the knee joint, improving knee joint load imbalance and correcting the mechanical equilibrium around the knee joint in patient with knee meniscus injury. It has a definite curative effect on the disease.

Hepatic fibrosis is a pathological process of chronic liver injury. Without timely intervention and treatment， liver fibrosis may eventually lead to liver cirrhosis and cancer. Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway is closely associated with the occurrence and development of liver fibrosis. Based on this， this paper summarized and analyzed the mechanism and effects of active ingredients and compounds of traditional Chinese medicine improving liver fibrosis based on JAK/STAT signaling pathway. It is found that the active ingredients and compounds of traditional Chinese medicine that promote blood circulation and remove blood stasis （ingredients such as ethanol extract of Euonymus alatus and paclitaxel， as well as compounds such as Ershiwuwei songshi pill and Ganfukang）， clear away heat and toxic material （ingredients such as betulinic acid， total flavonoids from Persicaria perfoliata， as well as compounds such as Pianzaihuang and Kehuang capsules）， and sooth the liver and promote qi circulation （ingredients such as fraxetin and cucurbitacin B， as well as compounds such as Chaihu shugan powder and Xiaochaihu decoction） can all relieve liver fibrosis by inhibiting the activity of the JAK/STAT signaling pathway， reducing inflammatory reactions， and inhibiting the proliferation of hepatic stellate cells.
