Objective To investigate the related factors that affect the short outcome of abdominal surgery among elderly patients with acute abdomen.Methods Clinical data of 378 patients aged >60 years with acute abdo-men were retrospectively analyzed.The key factors under analysis in this study were the occurrence of major complica-tions,death from any cause within 30 days and related factors after the operation.Results The most common diagno-ses were acute appendicitis (134 cases,35.4%),biliary tract disease (96 cases,25.4%),intestinal obstruction (68 cases,20.0%)and inguinal hernia(42 cases,11.1%).The majority of patients(327cases,86.5%)underwent open surgery.12cases(23.5%)of all 51 cases underwent laparoscopic surgery were converted to open surgery.The 30 day mortality rate and rate of operation -related complications were 9.5% and 22.0%,respectively.Analysis showed that patients'age,low body mass index,open surgery and ASA grade Ⅲ or above may increase mortality(all P <0.05).Conclusion The acute abdomen in elderly patients was with much complications,operation treatment is still the first choice.The patient's older age,low body mass index,open surgery may increase the mortality rate.ASA grade higher may predict a bad prognosis.The operation of elderly patiens had a high morbidity and mortality,as general surgeon,we should pay more attention to acute abdomen in elderly patients.

Objective:To explore the central neurobiological mechanisms of pleasure effect on rats with neuralgia treated by tuina manipulations of An-pressing and Rou-kneading Huantiao (GB 30).Methods:A total of 64 male Sprague-Dawley (SD) rats were used in this study.Eighteen rats were randomly selected as a normal group,and the other 46 rats were used to duplicate the chronic constriction injury (CCI) model.Ten rats failed in modeling and 36 rats succeeded.These 36 rats were then randomly divided into a model group and a tuina group,with 18 rats in each group.The rats in the normal group and the model group did not receive any interventions,while those in the tuina group received An-pressing and Rou-kneading Huantiao (GB 30),1 min for each time,once a day,3 weeks in total.Heating tests were evaluated to observe the change of pain-sensitivity score before intervention,1 week after intervention,2 weeks after intervention,and 3 weeks after intervention.After 1 week of intervention,2 weeks of intervention,and 3 weeks of intervention,6 rats were randomly selected from each group respectively for brain extraction.The change of Nissl's body and β-endorphin in the accumbens nucleus as well as amygdaloid nucleus of pleasure circuits,and pro-opiomelanocortin (POMC) in the arcuate nucleus were analyzed by methods of histochemistry and molecular biology.Results:After modeling,the pain-sensitivity scores of the tuina group and the model group were statistically different from the score of the normal group (both P＜0.05).After An-pressing and Rou-kneading Huantiao (GB 30) for one week,the pain-sensitivity score of the tuina group had statistical difference compared with that of the model group (P＜0.05).At each different time point:the amounts of Nissl's body in accumbens nucleus and amygdaloid nucleus of the tuina group were significantly more than those of the model group (all P＜0.01).Besides,the numbers of β-endorphin immunoreactive cells in the accumbens nucleus and amygdaloid nucleus of the rats in the tuina group were significantly higher than those in the model group (all P＜0.01),and so was the expression of POMC in arcuate nucleus (all P＜0.01).Conclusion:An-pressing and Rou-kneading Huantiao (GB 30),where the sciatic nerve is ligated,can reduce pain-sensitivity score and increase pain tolerance value of rats with chronic neuralgia.It can increase the activity of neurons in accumbens nucleus and amygdaloid nucleus of pleasure circuits,which indicates that the analgesia effect of tuina therapy may correlate with pleasure effect,and also reveals a part of neurobiological mechanisms of neuralgia.

Objective To investigate the variation law of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values in patients with cerebral infarction, and to explore the relationship between the changes and the prognosis of cerebral infarct patients. Methods Sixteen patients with cerebral infarction were recruited and divided into 2 groups:good recovery and poor rehabilitation. ADC and FA values were calculated in infarct areas and control areas which were the regions with symmetrical position and the same area as infarct areas. The difference of ADC and FA values in patients at acute and earlier chronic stage between the two areas were analyzed. Results ①At acute stage, ADC values in infarct areas were lower than those in control areas (P<0.05). At early chronic stage, there was no significant difference of ADC values between infarct areas and control areas (P>0.05), moreover ADC values were higher than that at acute phase (P<0.05). ②FA values in infarct areas were lower than those in control areas at both acute and early chronic stage (P<0.05). At early chronic stage, FA values were lower than those at acute stage (P<0.05). ③There was no significant difference of ADC and FA values at both acute and early chronic stage between good recovery group compared with poor rehabilitation group (P>0.05). Conclusion There are certainly rules in changes of ADC and FA values in patients with cerebral infarction at acute and earlier chronic stage.

Background Autologous and allograft renal transplantation exist some disadvantages of less donor source and rejection.As a scaffold of cell in tissue engineering,fibroin was determined to have a good biocompatibility.But whether the fibroin membrane can become a substitution for tissue defect is seldom reported.Objective This experiment aimed to investigate the feasibility of silk fibroin membrane in the rabbit eyelid reconstruction in situ.Methods A 4 mmx3 mm tarsi defect model was created on the upper eyelids of 18 healthy New Zealand white rabbits.The eyelid reconstruction in situ was performed with regenerated silk fibroin membrane material in the right upper eyelids (silk fibroin group ) and allogenic sclera material (sclera group ) on the upper eyelids of fellow eyes.The grafts were clinically examined for the evaluation of inflammation and implant exposure at the first,second and forth week after operation.The inflammation response and collagen distribution were examined by hematoxylin & eosin staining and Masson staining.Expression of basic fibroblast growth factor(bFGF) in the grafts was detected by immunohistochemistry,and ImagePro Plus software was used for statistical analysis.Results All eyelid defects showed a primary healing.The surface of palpebral conjunctival was smooth and the inflammation of ocular surface was mild.The eyelid margin in the sclera group was more notch than that in the silk fibroin group.Results of pathological examination revealed that the arrangement of collagen fibers in the sclera group was more disordered,but that in the silk fibroin group was regular.The expression level(A value) of b-FGF in the operative area in silk fibroin group were 0.027 67±0.004 69,0.051 73±0.008 72,0.058 72±0.006 88,and those in the sclera group were 0.056 48±0.009 14,0.072 83 ± 0.009 17 and 0.078 73 ±0.010 84 in 1,2,4 weeks after operation,showing statistically significant differences between two groups in various time points ( t =- 6.38,t =- 4.99,t =- 2.87,P ＜0.05 ).Conclusions Silk fibroin membrane can reconstruct the eyelid shape in situ with the less inflammation response and good biocompatibility.Silk fibroin membrane could be used to support the eyelid as a new tarsal repairing materials.

Background Research showed that exposure of 530 nm monochromatic light can induce myopia in animal,and retinal Müller cells participate in the formation of myopia.However,the effect and mechanism of retinal Müller cells during the formation of monochromatic light induced-myopia is below understood.Objective This study was to investigate biologic characteristics of rat retina Müller cells and the expression of cell factors in Müller cells after being illuminated by the 530 nm monochromatic light,and discuss the role of the retina Müller cells in myopia induced by monochromatic light.Methods Immortalized rat retinal Müller cells were cultured with DMEM containing 10％ fetal bovine serum in a self-made cell incubator with monochromatic light by adjusting luminance of 530 nm LED source.The cells were exposed to 125,250 and 500 lx luminance respectively for 6,12 and 24 hours,and the cells without light-irradiation were used as control.The growth of the cells under the different light time and different illuminations was described by MTT as the absorbance at the wavelength 570 nm (A570),and cell cycle analysis of Müller cells was performed by flow cytometry 48 hours after cultured,and the expression of transforming growth factor-beta 1 (TGF-β1),tyrosine hydroxylase(TH),inducible nitric oxide synthase(iNOS) and basic fibroblast growth factor(bFGF)in the cells were detected by reverse transcription PCR(RT-PCR),respectively.Results The Müller cells were uniform in size with polygonal shape and defined edges.No statistically significant difference was found in the A570 value in the cells of the 125 lx and 250 lx illuminated groups compared with the control group in various time points(P＞0.05).However,significant lowing was seen in the A570 value in the cells of the 500 lx illuminating for 12 hours and 24 hours in comparison with the control group (P =0.013,0.001).Compared with the control group,the ratio of the number between G2 and G1 phase was not significantly declined in 125 lx,250 lx illuminating for 48 hours (P =0.073,0.330),and the ratio in the 500 lx illuminating group was significantly lower than those in the 250 lx illuminated group and the control group (P =0.028,0.038).RT-PCR revealed that the expression of TGF-β1 mRNA in the cells was higher in the 250 lx illuminated group than that of the 500 lx illuminated group (P=0.006).The expression of iNOS mRNA was gradually upregulated in the 250 lx illuminated group compared with the control group (P =0.001),but that in the 500 lx illuminated group was downregulated (P =0.000).The expression of bFGF mRNA was raised in the 125 lx and 250 lx groups but reduced in the 500 lx group when compared with the control group(P=0.002,0.000,0.005).Also,the expression of TH mRNA was significantly increased in the 250 lx group(P=0.000),but decreased in the 500 lx group(P=0.000,P=0.001).Conclusions The monochromatic light of 530 nm can inhibit the growth of rat Müller cells and downregulate the expression of myopia-related cell factors and therefore exert effect in the formation of myopia.
