The lumbar facet joints osteoarthritis can be a potentially important source of low back pain.The risk factors of lumbar facet joints osteoarthritis has been systematic reviewed.Recent research shows that risk factors for lumbar facet joints osteoarthritis include advanced age(older than 50 years old),male or post-menopause female,relatively more sagittal orientation of the facet joints,a background of intervertebral disk degeneration and L4、5 spinal levels.An up-to-date knowledge of this subject can be helpful in diagnosis and treatment of low back pain.

AIM: To study mechanism of hepatocytic mitochondria damage following septic shock. METHODS: 30 SD rats were randomly divided into three groups: sham operation group, 12 h cecal ligation and puncture (CLP) group and 16 h CLP group. The model of septic shock was made by cecal ligation and puncture. The liver mitochondria respiratory control rate (RCR), phosphate/oxygen (P/O) and ATPase activities were assayed. RESULTS: In 12 h CLP group mean artery pressure (MAP) [(9.54?1.26) kPa] was significantly lower than sham operation group [(14.58?1.32) kPa, P

ObjectiveTo explore the role of tumor necrosis factor related apoptosis inducing ligand (TRAIL) and it's combination with chemotherapeutic agents in treatment of cervical cancer.Methods 100μl of cervical cancer cells suspension were added to each well of 96 well plates. Cells were incubated for 24 hours with TRAIL, Adriamycin (ADM), Mitomycin C (MMC) and TRAIL combined with chemotherapeutic agents at different concentration. Rates of apoptosis and death of cells were detected by flow cytometry.ResultsRates of apoptosis of cells were 20.1% by treated with 100 μg/L TRAIL singly, which was significantly different compared with groups without agents (P<0.01). Inhibitory rates were 36.0% by treated with 10.0mg/L MMC, 44.1% by ADM. However inhibitory rates reached 58.4% or 73.7% by 100.0 μg/L TRAIL +10.0 mg/L MMC or ADM. Combined of TRAIL and MMC, TRAIL and ADM resulted in a synergistic cytotoxic effect (P<0.05).ConclusionIn vitro, TRAIL is an agent for anti cervical cancer by inducing the apoptosis of tumor cell; TRAIL can enhance the effect of ADM and MMC.

Objective To explore the early diagnosis and treatment of acute superior mesenteric arterial embolism (ASMAE).Methods The clinical data of 25 patients with acute superior mesenteric arterial embolism were retrospectively analyed.Results All 25(100%) patients had severe abdominal pain with abdominal signs,21(84%) patients had history of valvular heart disease or atrial fibrillation,and 17(68%) patients had hematochezia.All the cases were misdiagnosed preoperatively,including 11 patients were misdiagnosed as abdominal pain of unknown causes,3 patients as acute pancreatitis,3 patients as acute gastroenteritis,2 patients as necrotizing enteritis.1 patient as acute appenditis,1 patient as acute myocardial infarction,and 1 patient as acute cholecystitis;but 3 patients were preoperatively suspected to have impairment of mesenteric blood flow.All of the 25 patients underwent necrotic bowel resection,6 patients died,and 7 patients abandoned treatment because of serious complications such as short bowel syndrome etc.Mortality rate was 51%(13/25).Conclusions Early diagnosis of patients with acute superior mesenteric arterial embolism is difficult;the main cause of misdiagnosis is lack of recognition of its clinical signs.Fully grasping the characteristics of patients with early stage disease and effective early intervention are the fundamental measures for reducing mortality.

Objective To explore the role of protein kinase(PKC)in the nosogenesis of hypoxic-ischemic encephalopathy(HIE).Methods Twenty-four seven-day-old SD rats were divided randomly into normal group (N),model control group(C)and HIE group(HIE).The biochemistry techniques of SDS-PAGE and western bolt were used to examine the level of PKC membrane translocation of cortex and hippocampi.Results The level of PKC membrane translocation of cortex and hippocampi in N group was 0.28±0.02,0.29±0.02 respectively,and 0.29±0.02,0.30±0.02 in C group,and 0.38±0.04,0.40±0.06 in group HIE.The level of PKC membrane translocation of cortex and hippocampi was higher in HIE group as compared with that in N,C group(P＜0.01),but there was no different between N group and C group(P＞0.05).Conclusion PKC are activated in HIE,which indicates that PKC may involve in the pathophysiologic mechanism of HIE.

Port-wine stains(PWS)are a common congenital capillary malformation. The lesions of PWS appear to gradually darken in color and thicken with age, and even progress into nodules in late stage. Based on the principles of selective photothermolysis, pulsed dye laser (PDL)has become a standard treatment for PWS. However, for some intractable PWS, single PDL treatment shows unsatisfactory and even no effects. Considering this state, the authors summarize multiple treatment strategies for intractable PWS with thick or nodular lesions, providing a reference for their treatment.

Colorectal cancer is currently the world's fourth incidence of malignant tumors,the early clinical manifestations are not obvious,so the early diagnosis is difficult to find,most of them are in progress.Treatment of advanced stage with chemotherapy,interventional therapy,radiotherapy and other methods,in which chemotherapy in the killing of tumor cells at the same time,the normal cells of the body also has a killing effect.In recent years,all kinds of new nano targeting delivery system has been developed,which can be targeted to the tumor tissue,so it is more and more important in the treatment of intestinal tumor,especially with metastasis.The author has made an overview of the types of nano drug carrier materials,the research status and its application in the research of colorectal cancer.

Objective To establish the method of fingerprint analysis on Yupingf eng Decoction,and to study the correlation of HPLC fingerprint in Radix Astraga li,Radix Saposhnikovlae,Rhizoma Atractylodis Macrocephalae and Yupingfeng Deco ction. Methods HPLC with Hypersil ODS was used,acetonitrile -water(gradient el ution) as a mobile phase and detection wavelength at 220 nm,flow rate was 1 mL ?min-1,and column temperature was 30 ℃. Results There were 9,8 and 7 common peaks separated from 10 batches of medicinal material of Radix Astragali,Radix Saposhnikovlae,and Rhizoma Atractylodis Macrocephalae,respectively;11 common peaks were separated from 10 batches of Yupingfeng Decoction,of which 6 peaks were shared by Radix Astragali,4 peaks by Radix Saposhnikoviae and 1 peak by Rh izoma Atractylodis Macrocephalae. Conclusion There exists a correlation of Yupin gfeng decoction with the medicinal pieces of Radix Astragali and Radix Saposhnik oviae. The major characteristic fingerprint peaks of Yupingfeng decoction belong to those of the isoflavones from Radix Astragali and chromones from Radix Sapos hnikoviae. This will provide a reference for the rules of the compatibility and component research of Yupingfeng Decoction.
