Research on post-marketing Chinese medicine should be the systematic study from application to mechanism. Clinical evaluation is the basis of mechanism study, we can find the clue from clinical evaluation, then make a mechanism study to find the reason, then apply the results to clinic. So it is a virtuous circle. In order to achieve it, we cannot be limited to traditional Chinese medicine, we should form multi-disciplinary team under the direction of grand science thinking, try hard to put industry-university-research institute collaboration association to use, and if necessary, explore the new model of the whole nation system. An appropriate operation mechanism is very important.

OBJECTIVETo compare the efficacy of internal fixation (including PFNA and PFN) versus hip replacement (including FHR or THA) in the treatment of trochanteric fractures in adults.

METHODSReports of studies using randomized controlled trials (RCT) to compare internal fixationg with hip replacement in the management of intertrochanteric fractures were retrieved (up to January 1, 2013) from the Cochrane Library, PUBMED Data, CNKI (China National Knowledge infrastructure), Elsevier, the Chinese Biomedical Database, Wanfang Data, and manually. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software RevMan 5.0 was used for data-analysis.

RESULTSSeven articles were included in the meta-analysis. The results showed that,compared internal fixation with hip replacement,there were statistical significance in the duration of surgery time [WMD = -2.66, 95% CI (-5.25,-0.06), P = 0.05], intra-operative blood loss [WMD = -24.20, 95% CI (-30.38, -18.02), P < 0.000 01], hospital stays time [WMD = -4.72, 95% CI (-5.18, -4.25), P < 0.000 01], bearing load time [WMD = -29.54, 95% CI (-30.77, -28.31), P < 0.000 01], total complications rate [WMD = 0.15, 95% CI (0.11, 0.22), P < 0.000 01], the good rate of Harris scores [WMD = 1.09, 95% CI (0.54,1.32), P < 0.05]. However, there were no statistical significance in the rate of deep venous thrombosis [WMD = 1.09, 95% CI (0.47, 2.55), P > 0.05]. CON- CLUSION: Hip replacement (containing FHR or THA) for the treatment of intertrochanteric fractures is superior to internal fixa- tion in regards to the duration of surgery time, the mean duration of hosipital stays, mean post-operative down time, intra-opera- tive blood loss, the rate of post-operative good Harris scores. But there is not enough evidence to show any difference between hip replacement (containing THA or FHR) and internal fixation in regards to the rate of deep venous thrombosis. However, internal fixation for the treatment of intertrochanteric fractures is superior to hip replacement (containing FHR or THA) in regards to total complications rate.

Objective:To study the chemical constituents in the dried buds of Lonicera similis.Method:Chromatography and spectral analysis were used to isolate and elucidate the constituents.Result:Nine compounds were isolated from the dried buds of L． similis，and identified as caffeic acid；3，5-O-dicaffeoylquinic acid；chlorogenic acid；palmitic acid；luteolin；quercetin；β-sitosterol；nonacosanol；nonacosane.Conclusion:All the compounds were isolated from the plant for the first time.

Objective To review our clinical experience on 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic debridement.Method This retrospective study included 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic dehridement and drainage.Results All the 12 patients recovered well and were finally discharged home.Conclusions Retroperitoneal laparoscopic debridement and drainage for retroperitoneal infection is a mini-invasive procedure.It was found to be safe,produced minimal bleeding and resulted in rapid postoperative recovery.It can be used as the first choice treatment in properly selected patients.

Objective To summarize and discuss the diagnostic and treating experiences of chronic pancreatitis with mass in the head. Methods Eight patients of chronic pancreatitis with mass in the head who were misdiagnosised as carcinoma of head of pancreas were analyzed retrospectively in the past 10 years. Results All the patients exhibited abdominal pain,5 of whom were with jaundice and 3 with anorexia. All the patients were misdiagnosised as carcinoma of head of pancreas before the operation,but the pathology after operation indicated chronic pancreatitis. The pancreaticoduodenectomy was performed in 5 patients,the choledochojejunostomy in 2 patients,while the exploratory laparotomy in 1 patient. After the operations,the abdominal pain was relieved in 7 patients, while 2 patients who accepted pancreatoduodenectomy suffered from pancreatic fistula,1 of whom died in the end. Conclusion It’s hard to differentiate the chronic pancreatitis with mass in the head from the carcinoma of head of pancreas before operation. If the carcinoma of head of pancreas can’t be excluded during the operation,the pancreatoduodenectomy should be performed,while the duodenum-preserving total resection of the head of the pancreas or any intra-drainage operations should be done if chronic inflammation is found in the whole pancreas with a negative result of the biopsy of the pancreas through the needle aspiration.

Background Recently,there were many studies on corneal innervations during mammalian development.However,there were fewer studies on discussing corneal innervations before and after mouse eye openings.Objective The present study was to investigate the change in the regulation of corneal nerve fiber length and density before and after mouse eye openings to offer a basis for clinical research in human.Methods Thirty SPF C57BL/6 mice were divided into postnatal 1 day(P1 d),P7 d,P13 d(1 day before eye opening),P14 d(eye halfopened),P17 d(1 day after eye opening)and P23 d(7 day after eye opening)groups,with 5 mice and 10 eyes for each group.Entire corneal stretches were prepared and immunostaining with an anti-neuron-specific β-Ⅲ tubulin antibody was performed to label the corneal nerve fibers.Confocal microscopic pictures from the corneal dorsal-nasal region (DN),dorsal-temporal(DT),ventral-nasal region(VN)and ventral-temporal(VT)were taken using Delta Vision Core.From these pictures,the mouse corneal area,total length and density of nerve fibers in the 4 regions were calculated.The use of the animals complied with Statement of ARVO.Results Corneal areas of P1 d,P7d,P13 d,P14 d,P17 d and P23 d mice were(0.404±0.007),(1.362±0.154),(1.573±0.080),(1.603±0.046),(1.847±0.052),(2.445±0.798)mm2,respectively ; the total lengths of nerve fibers were(3.718±1.044),(19.065±3.350),(23.687±0.907),(27.309±2.477),(31.989±3.976),(41.214±1.573)mm,respectively ; the densities of nerve fibers were(9.592±1.138),(14.506±1.908),(15.088±1.241),(16.772±1.897),(16.821±2.102),(17.660±1.216)mm/mm2,respectively,all showing significant increases with age(F =22.906,P =0.000 ; F =0.424,P =0.000 ; F =2.375,P=0.000).A positive correlation of the increasing corneal areas and increasing lengths of nerve fibers was found(r=0.983,P＜0.01).Nerve fiber densities in the four corneal regions significantly increased with age(DN region:F =0.159,P =0.000 ; DT region:F =2.1 72,P =0.001 ; VN region:F =1.998,P =0.000 ; VT region:F=2.352,P=0.000).From P13 d to P14 d,the corneal nerve fiber densities in the DN region decreased by 6.0％ without significant difference(t =0.589,P =0.572); and the corneal nerve fiber densities in the DT region,VN region and VT region decreased by 4.6％,5.5％ and 0.1％,respectively,without significant difference from P14 d to P17 d(t=0.549,P=0.596;t=0.701,P=0.501 ;t=-0.100,P=0.919).Conclusions The development of nerve fibers in the whole cornea or the four corneal regions is influenced by eye opening in mouse to various extents.From P13 d to P14 d,the corneal nerve fiber densities in the DN region decreased by 6.0％ without significant difference.From P14 d to P17 d,the corneal nerve fiber densities in the DT region,VN region and VT region decrease by 4.6％,5.5％ and 0.1％,respectively,without significant difference.Afterwards,the growth of nerve fibers increased in pace and the growth rate is recovered.
