Objective To investigate the synergistic effects of pirarubicin (THP) combined with hyperthermia on proliferation and invasive potential of gastrointestinal cancer cells in vitro and to discuss the underlying mechanisms. Methods Gastric cancer cell line MGC-803 was established, and they were divided into 4 groups: control group (37℃), high temperature group (43℃), drug group (37℃+THP), and drug and high temperature group (43℃+THP). After THP and hyperthermia treatment, cell proliferative ability was determined by soft agar clonogenic assay, cell nuclear antigen PCNA was detected by flow cytometry, cyclin E mRNA level was assessed by reverse transcription PCR (RT-PCR). Cell invasion assay was assessed by using transwell chamber model. Results Strong synergistic inhibitory effects on clonogenic ability of MGC-803 cells were observed after MGC-803 cells were treated with pirarubicin in combination with hyperthermia (P

BACKGROUND: Complications, caused by bile duct injury after liver transplantation, are difficult for diagnosis and treatmerit and the bottlenecks for the development of liver transplantation. OBJECTIVE: To observe and record bile duct injury and do biopsy in parallel with treating biliary complications following liver transplantation successfully with choledochoscope, and to analyze the relationships between various bile duct injuries, histopathological types and biliary complications following liver transplantation. DESIGN, TIME AND SETTING: Case analysis was carried out at Dalian Institute of Hepatobiliary Surgery, Department of Hepatobiliary Surgery. Dalian Friendship Hospital between July 2001 and October 2005. PARTICIPANTS: Nineteen patients after liver transplantation were divided into three groups according to the occurrence of biliary complications: four cases for normal group, twelve cases for bile duct injury group, three cases for hepatic artery miury group. METHODS: They were observed. diagnosed and recorded respectively and take biopsy for pathological analysis through the choledochoscope. With regard to the cases without T-tube. Choledochoscope combined duodenoscope were used to take biopsies. MAIN OUTCOME MEASURES: Choledochoscope was used to observe T-tube cholangiography, the appearances and pathological changes of intemal and external bile duct mucous membrane. healing of the donor-receptor bile duct stoma. Patients in the bile duct injury group were done examinations described above after endoscopic stone extraction and stenosis expansion. RESULTS: The intemal and extemal bile duct anatomy of the patients in the normal group were normal, without bile ductstenosis and scar, their bile duct mucous membrane lookcd good, and the anastomosis of the donor-receptor bile duct healed well. Restored mucous tissue coating with intact epithelium was found by pathological examination. Various kinds of bile duct stones, simple, multiple and casting mould stones, were found in patients of the bile duct injury group. Bile duct mucous membranes were injured at different degrees and repaired after removing stones and relieving obstruction by endoscope. Contrast examination demonstrated that bile duct tree regained normal. In hepatic artery injury group, patients had bile duct wall ischemic necrosis and lost bile duct normal structure, congestion was obvious, biliary sludge and stones completely filled in the bile duct tree. Interrupted bile duct structure were found in Ⅲ grade bile ducts.Pathological examination revealed extensive bile duct wall necrosis,indistinct strcture,more bile infiltration,proliferative granulation tissue and suppuration focus.CONCLUSION:Bile ducts are injured at different degrees in orthotopic liver transplantation;cold preservation/repeffusion injury is the most important initiating agent leading to bile duct tree injuries;the vessel plexus damage and microcirculatory disturbance surrounding the bile ducts maybe one of the mechanisms of the bile duct injury.

Objective Objective The present study was to increase the awareness of nonalcoholic Wernicke's encephalopathy ( WE) to reduce its misdiagnosis.Methods The clinical features and MR imaging findings in 6 patients with nonalcoholic WE were retrospectively analyzed.Results All patients exhibited different degrees of unconsciousness.Only two patients presented with the typical triad of neuro-ophthalmologic manifestations, ataxia, and global confusion.All patients presented with typical MR features characterized by bilaterally altered signal of the medial thalamus, periventricular region of the third ventricle and periaqueductal area. In addition, two patients developed symmetric cortical and facial nerve nucleus involvements with deep coma, which was clinically rare.The average clinical recovery and MRI imaging recovery times were 7.5 months and 2.8 months, respectively,.Two patients with deep coma showed a poor prognosis:1 patient died, and the other had a sever spastic paralysis of her extremities and mental retardation during a follow -up of 2 years.Two patients with deep coma showed symmetric hyperintensities on diffusion -weighted imaging ( DWI) .Conclusions MRI images are useful in the early diagnosis of nonalcoholic WE.Cortical and cranial nerve nucleus involve-ment in nonalcoholic WE patients may be an indication of irreversible damage and a poor prognosis.In addition, hyperintensities on DWI may also indicate an unfavorable prognosis.

OBJECTIVETo observe the difference in acupuncture for pain threshold at different time points among the groups of 9 TCM constitutions.

METHODSThe cross-sectional survey was adopted to investigate TCM constitutions among 600 subjects and determine 9 TCM constitution types (neutral constitution, qi-deficiency constitution, yang-deficiency constitution, yin-deficiency constitution, phlegm-damp constitution, damp-heat constitution, blood-stagnation constitution, qi-stagnation constitution, special diathesis constitution). The same acupuncture manipulation was applied to Zusanli (ST 36) on the left side in the subjects and the needle was retained for 30 min. The tenderness threshold was detected with 2390 type Von Frey apparatus at different time points, named before acupuncture, at the moment after qi arrival, in 10 min of needle retaining, in 30 min of needle retaining and in 15 min after needle withdrawal in the subjects of 9 TCM constitutions.

RESULTSThe interactive effect happened between the constitution type and time point (P < 0.05). Among the groups of 9 TCM constitutions, the pain threshold values at the moment after qi arrival (except blood-stagnation constitution, qi-stagnation constitution, special diathesis constitution) in 10 min of needle retaining and in 30 min of needle retaining were increased as compared with those before acupuncture separately (P < 0.01), among which, the value increase was the most significant in 30 min of needle retaining. The differences in the pain thresholds were significant in 15 min after needle withdrawal in the groups of neutral constitution and damp-heat constitution as compared with those before acupuncture (both P < 0.01). In 10 min of needle retaining and in 30 min of needle retaining, as compared with the group of neutral constitution, the changes in pain thresholds of the rest abnormal constitutions were apparently lower (all P < 0.05).

CONCLUSIONAcupuncture at Zusanli (ST 36) presents different effects among the groups of different constitution types. The effect maintaining durations are different.

Objective To study the relationship between intrarenal arterial lesions(IAL)and carotid atherosclerosis(AS)in patients with renal glomerular disease.Methods 251 cases with IAL were selected and 129 age-,pressure-and eGFR-matched renal glomerular disease cases without IAL were randomly selected.The carotid intima-media thickness(IMT)was detected.Clinical and laboratory examination and renal histological characteristics were compared the two guoups.Results ①The detection rate of carotid AS was higher in patients with IAL than those without IAL(38.2%vs.20.2%),and higher in patients≥40 years than in patients＜40 years(51.3%vs.13.1%)(P<0.05 for each). ②The carotid AS group was older and had higher frequencey of fasting blood glucose,body mass index,smoking,and family history of hypertension,longer duration of established hypertension and renal glomerular disease,higher prevalence of hypertension,IAL and renal lesions,and had lower eGFR than the carotid normal group(all P＜0.05).Binary logistic regression analysis revealed that IAL and age emerged as an independent risk factor for carotid AS(OR=1.826 and 1.129,P=0.001 and 0.003).Conclusion The intrarenal arterial lesion is an independent risk factor for carotid atherosclerosis in patients with renal glomerular disease.Controlling blood glucose,blood pressure,weight,smoking quit and delaying progression of kidney disease have important significance in relieving or preventing atherosclerosis and intrarenal arterial lesions of patients with renal glomerular diseases.

Objective To observe the effects of deep electroacupuncture on carlilage tissue in knee osteoarthritis (KOA) rabbits. Meth-ods 40 New Zealand rabbits were randomly divided into normal group (A, n=10) and model group (n=30). The model group was modeled KOA with Hulth-Telhag way, and identified with X-ray. Then they were divided into no-treated group (B, n=10), deep electroacupuncture group (C, n=10) and routine electroacupuncture group (D, n=10) randomly. The groups C and D accepted electroacupuncture since 6 weeks after modeling, for 4 weeks. They were measured with pH of joint fluid, observed structure and pathology of cartilage under transmission electron microscope, detected apoptosis index, and determined the expression of acid-sensing ion channel 1 (ASIC1), p38 mitogen-activated protein kinases (p38MAPK) and p53 with Western blotting, and distribution of ASIC1 with immunohistochemistry in cartilage tissue. Re-sults The pHs of joint fluid from high to low were ranged as the groups A=C>D>B (P<0.01). The cartilage structure was more complete in the groups A, C and D than in the group B. The apoptosis rates from less to more were ranged as the groups A=C

As the specific endangered medicinal plant in Xinjiang, resources and distribution of Ferula sinkiangen-sis are important for biodiversity conservation and sustainable development of Chinese medicine resources. The spa-tial distribution and resources of F. sinkiangensis were researched based on low altitude remote sensing and sample investigation. The results showed that the optimum working time for F. sinkiangensis monitoring by low altitude remote sensing was the nearby 5 hills, which covered about 0.88 km2. It was suggested that the fence area should be expanded for protection. According to the results of low altitude remote sensing, the amount of F. sinkiangensis in yellow (diameter exceeding 0.3 m) was about 3 191. However, the sample investigation on amount of F. sinkiangensis in yellow (diameter exceeding 0.3 m) was about 2 752. The error between them was 14%. The monitoring time and range for F. sinkiangensis by low altitude remote sensing were also ensured. It was concluded that low altitude re-mote sensing had the advantage of quickly receiving distribution situation of F. sinkiangensis, which can effectively evaluate dynamic changes of F. sinkiangensis in Xinjiang.

BACKGROUND: Greater tuberosity of humerus, as the attachment point of rotator cuff, plays a vital role in shoulder.Neer and AO classification for proximal humeral fractures have been accepted extensively. However, the classification for single greater tuberosity fractures of the proximal humerus is little reported, and its fixation method remains controversial.OBJECTIVE: To explore the curative efficacy of the double-row suture anchors under arthroscopy for avulsion-type greater tuberosity fractures (Mutch type Ⅰ) METHODS: Clinical data of 24 patients with avulsion-type greater tuberosity fractures (Mutch type Ⅰ) undergoing double-row suture anchors under arthroscopy were analyzed retrospectively. The displacement distance of the greater tuberosity of humerus was measured on CT before and after fixation. The shoulder joint was evaluated by Constant-Murley Score and the University of California, Los Angeles score at baseline, 1, 3, 6 and 12 months postoperatively. Besides, the visual analogue scale scores were detected at baseline and 12 months postoperatively.RESULTS AND CONCLUSION: (1) Double-row suture anchors effectively improved the displacement of greater tuberosity and rotator cuff injury. (2) The patients accompanied by rotator cuff injury accounted for 79.16%. (3) The Constant-Murley Score and the University of California, Los Angeles scores were significantly improved at each time point (P < 0.05). The visual analogue scale scores after fixation were significantly superior to those before fixation (P < 0.05). (4) These results suggest that the double-row suture anchors under arthroscopy can effectively improve the displacement of greater tuberosity and alleviate the pain. Moreover, it is conductive for early recovery of the shoulder function with little trauma, so it is a good choice for avulsion-type greater tuberosity fractures (Mutch type Ⅰ).
