Objective To investigate the risk factors for deep vein thrombosis (DVT) of lower limbs after laparoscopic surgery.Methods A total of 230 patients underwent laparoscopic surgery were selected in Huanggang Central Hospital from January 2014 to August 2016.The patients were divided into DVT group and non-DVT group according to DVT of the lower limbs,and the related risk factors for DVT of lower limbs after laparoscopic surgery were analyzed.Results In the 230 patients,there were 10 patients with DVT of lower limbs and 220 patients without DVT of lower limbs,the incidence of DVT of lower limbs was 4.35％ (10/230).Logistic regression analysis showed that age ≥40 years old,operation time ≥120 min,postoperative ambulation time ≥ 30 h,the intraoperative position of high-head and low-foot,plasma D-Dimer level ≥0.5 mg · L-1 were the independent risk factors for DVT of lower limbs after laparoscopic surgery (P ＜ 0.05).Conclusion There is a certain incidence of DVT of the lower limbs after laparoscopic surgery.The effective prevention measures should be taken to reduce the incidence of DVT after laparoscopic surgery according to the related factors of DVT.

Objective: To investigate the quality of life (QOL) and its influence factors in the scattered elderly in Shanghai, and to evaluate the effect of nutrition status on the QOL. Methods: Ninty-five randomly-selected elderly were investigated with QOL questionnaire, food frequency questionnaire and 24 h dietary recalls, their nutrition status were awarded by nutrient intake and medical examinations. Results: The percentage of poor, moderate and good QOL were 1.05%, 61.05% and 37.89%. The significant influence factors of QOL were health status, nutrition status, livelihood satisfaction, mentality health, family harmony, medical examination and income. The main nutrition intake of the 95 cases were sufficient, such as energy, protein, but the intake of diet fat and salt were overtaken. The rate of overweight and obesity were 26.3% and 40.0%. Conclusion: Nutrition status is the main influence factor of QOL in the elderly. To improve the QOL of the elderly, health education and balance nutrition guidance should be strengthened.

Objective:To study the expression of IFN-γ,IL-4 and IL-17 in peripheral blood of patients with oral lichen planus(OLP). Methods:The level of IFN-γ,IL-4 and IL-17 in peripheral blood were detected by ELISA in 60 OLP patients(including 30 erosive ca-ses and 30 non-erosive cases)and 25 healthy volunteers(controls).Data were statistically analyzed by SPSS 13.0.Results:(1 )The level of IFN-γin serum of patients with non-erosive OLP and erosive OLP were significantly lower than that in the controls(P<0.01);while the level of IL-4 in the patients were significantly higher than that in the controls(P<0.01),and the IFN-γ/IL-4 ratio in non-ero-sive OLP and erosive groups were significantly lower than that in the control group(P<0.01);(2)The level of IL-17 in erosive OLP pa-tients was significantly higher than that in the controls(P<0.05),while no statistical difference was seen between non-erosive OLP group and the control group(P>0.05).Conclusion:The down-regulated level of IFN-γand up-regulated level of IL-4,which result in the decrease of IFN-γ/IL-4 ratio,might be one of the immune etiological factors of OLP,while the up-regulated level of IL-17 protein in OLP may be mainly related with the inflammatory processes of OLP.

Objective To study the synthesis and degradation of collagen at the transcription level during liver fibrosis in rabbits with schistosomiasis japonica. Methods New Zealand rabbits infected with Schistosoma japonicum cercariae were served as animal models of liver fibrosis. The liver specimens were collected through operations at 4, 6, 8, 10, 12, 16, 20, 24 and 28 weeks after infection. TypeⅠcollagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels of liver tissue were detected by RT\|PCR plus dot blotting, and the size of egg granulomas and the degree of liver fibrosis were measured by histopathological examinations. Results TypeⅠcollagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels increased simultaneously in the early stage after the infection, mostly reaching their peaks at 10 weeks after infection. Compared with normal controls, type Ⅰ collagen, type Ⅲ collagen, type Ⅳ collagen, MMP\|1 and MMP\|9 mRNA levels increased by 12\^0 , 11\^0 , 6\^6 , 10\^0 and 11\^0\|fold, respectively, coinciding with the changes of egg granulomas. Thereafter, both collagen and collagenase mRNA levels decreased. TypesⅠ, Ⅲ and Ⅳ collagen mRNA levels declined to 2\|fold to 3\|fold compared with normal controls ( P 0\^05) at 28 weeks. This study showed that the synthesis and degradation of collagen remained dynamic balance in the early stage of schistosomiasis, while in the later stage the metabolism of collagen synthesis was higher than that of collagen degradation. Conclusion It was confirmed at the transcription level that when the metabolism of collagen synthesis was higher than that of collagen degradation in rabbits with schistosomiasis japonica, liver fibrosis might be produced.

Objective To analyze the relationship between the morphological characteristics and rotator cuff tear (RCT) by MR.Methods The data of clinic and shoulder MRI of 37 patients with RCT (patients group) were analyzed retrospectively,and 19 healthy volunteers were collected in control group.The acromial shapes were classified into type Ⅰ (flat),type Ⅱ (curved),type Ⅲ (hooked) and type Ⅳ (convex).Additional measurements about pathogenesis of RCT including acromio-humeral distance (AHD),acromial index (AI),lateral acromial angle (LAA) and acromial thickness were performed for further assessment.Results Type Ⅱ was the most commonly encountered acromial shape in patients group (16/37,43.24 ％) and control group (11/19,57.89 ％).There was no statistically significant difference in the incidence of each acromial shape between two groups (P＞0.05).However,the AHD,AI,LAA and acromial thickness showed statistically significant difference between the patients group and control group (all P＜0.05).The type Ⅲ acromion was signifi candy different from the other types in patients group (P＜0.05).Conclusion MRI can clearly display RCT.The AHD and LAA are smaller,the AI and acromial thickness are bigger in RCT patients.Type Ⅲ acromion may increase risks for RCT.

BACKGROUND: With the rapid development of surgical techniques, unicompartmental knee arthroplasty has become an issue of concern in the treatment of osteoarthritis, which has achieved significant progress inreducing trauma and rapid rehabilitation.OBJECTIVE: To summarize the development history, curative effect of unicompartmental knee arthroplasty, and the research progress of lateral unicompartmental knee arthroplasty aided with computer navigation or robot system, thus providing reference for further study on unicompartmental knee arthroplasty.METHODS: Web of Science, and PubMed databases were searched for the literatures published from January 1955 to April 2017 with the keywords of unicompartmental knee arthroplasty, osteoarthritis, unilateral compartment, lateral knee arthroplasty.RESULTS AND CONCLUSION: A total of 562 articles were retrieved, and finally 75 English literatures were enrolled according to the inclusion and exclusion criteria. With the continuous improvement of unicompartmental knee arthroplasty, it can retain the cruciate ligament and more bone mass. Notably, strict indications and reasonable postoperative functional exercise are essential for obtaining optimal effectiveness. At the same time, the development of computer navigation and robot-assisted technology has opened up a new horizon for the treatment of osteoarthritis,which makes the operation more accurate and minimally invasive. But the application still needs to be studied in depth.

Objective To investigate the relationship between acute biliary pancreatitis (ABP) and anomalous pancreaticobiliary duetal union (APBDU). Methods 131 patients with ABP were enrolled to test the serum total bilirubin (TB), alanine amintransferase (ALT), aspartate amintransferase (AST), alkaline phosphates (ALP), γ-glutamyl transferase (γ-GT). All the patients received medical treatment, and then these tests were performed again. Thereafter, all the patients underwent selective surgery and intra-operative cholangiography was performed to observe the pancreaticobiliary duetal union. Results 27 patients (20.6%) with APBDU were found in 131 patients. Among them, 8 cases (29.6%) was B-P subtype (TypeⅠ), 16 cases (59.3%) was P-B subtype (TypeⅡ) , and the remaining 3 cases was mixed subtype (TypeⅢ). A significant decrease of ALT, AST, ALP, γ-GT after non-surgical treatment in both group of APBDU and NAPBDU was noted (P＜0.05). The serum levels of ALT, AST,γ-GT in APBDU patients were (71.81± 23.19) U/L, (47.85±27.87) U/L, (52.86±31.49) U/L, respectively; and in NAPBDU patients were (51.96±15.40) U/L, (40.77±16.58) U/L, (34.86±26.47) U/L. The difference was statistically significant (P＜0.05). Condusions APBDU is an important etiology of ABP.

Objective To develop experimental animal model of the brain stem myoclonus,which more closely replicate clinic features of mechanism, behavior, neuroelectrophysiology and pharmacodynamics.Methods L-5-HTP (the precursor of L-5-HT)was microinjected into the dorsal pons of young guinea pig to induce myoclonus (electromyogram burst of myoclonus≤400 ms by synchronous recording).Some animals were pretreated with anticonvulsant VPA,CZP or CBZ at effective dose 50 (EC_(50)).Myoclonus was induced when the drug level was within their effective anticonvulsion concentration.The neuroelectrophysiological characteristics of myoclonus including latency,time of reaching its peak,duration of seizure peak,the maximum seizure frequency and total duration were detected.EMG and ictal electroencephalogram(EEG)were recorded synchronously.The origin of myoclonus and its correlation with epileptic discharges were further confirmed by jerk-locked back averaging(JLA).Results (1)L-5-HTP induced pure myoclonus from the dorsal pons of guinea pig permanently(8/every site,the rate of producing myoclonus is 100%).(2)The myoclonus presented bilaterally or as general myoclonus,which was sensitive to tactile and sound sensation.(3)The EMG duration of the myoclonus wag longer((208.75 ± 81.42)ms),and ictal EEG showed scattered and irregular spikes and sharp waves without time-locked correlation with EMG activities.(4)The synchronous ictal EEG of the myoclonus showed spike and sharp waves,but there was no time-locked EEG activity in JLA.(5)In the animals treated with anticonvulsant at EC_(50) concentrations:VPA and CZP decreased the maximum seizure frequency(there are 28.13±3.79 per minutes in VPA group and 37.17±4.67 perminutes in CZP group)and shortened the duration of peak time ((55.00±14.14)minutes in VPA group and(50.00±11.73)minutes in CZP group respectively)and total time(VPA group was(124.17±40.04)minutes and CZP group was(156.88±30.71)minutes)of myoclonus(F value were between 23.41 and 35.44,P＜0.01 or P＜0.05).CBZ increased duration of peak time((98.75±13.86)minutes)and total time((257.50±14.79)minutes)of myoclonus(P＜0.05 and 0.01).Conclusions The new model generates pure myoclonus originating from brain stem and also has a shorter duration of muscle construction(≤400 ms)and more sensitivity to tactile and sound sensation.Therefore,the model presents characteristics closer to the brain stem myoclonus in the clinic phenotype in respect of seizure behavior,pharmacodynamics and neuroelectrophysiology.
