This article explains four cases of professor REN Ji-xue,including anasarca,serious blepharoptosis,head cold,summer diarrhea,from which we can find the laws of syndrome differentiation by him. In which,the key point of the pathogenesis of anasarca is spleen-qi deficiency, so replenishing qi and invigorating the spleen, warming yang for diuresis are the treatment nethod for anasarca. Sinking of qi due to deficiency of spleen leads to serious blepharoptosis and Invigorating Spleen and Replenishing Qi Decoction is the main prescription. The key pathogenesis of head cold is disharmony of nutrient qi with defensive qi, so regulating ying and wei, dispersing lung qi for resuscitation are the treatment methods, and both inside and outside therapies are in use. Cold-damp invasion of spleen is the main cause of summer diarrhea, so activating qi flowing and warming spleen and stomach, dissipating dampness for stopping diarrhea are used. Professor REN Ji-xue is good at taking different method according to different key point of the pathogenesis, so the efficiency is good. This is one feature of Professor REN in treating miscellaneous diseases.

Objective To observe the changes in enteric motor function and acetylcholine esterase(AchE)neuron and nitric oxide synthase neuron(NOS)in enteric nervous system after different abdominal operations,and to explore the mechanism of these changes.Methods Sprague Dawley rats were divided into experimental groups(laparotomy group,intestine massage group and intestinal operation group)and the control group.Rats in each group were gavaged with medicinal carbon powder,and then the transimission of carbon powder in small intestine was determined,and the spreading specimens of intestinal myenteric plexus of small intestine and large intestine were collected and stained with AchE and nicotinamide-adenine dinucleotide phosphate-D(NADPH-d)for histological study,and the density of distribution and positive stained AchE and NOS neurons were observed and compared.Results The changes in enteric motor function:the propellant rate of carbon powder was slower in enteric massage group and intestinal operation group than that in laparotomy group and control group(18.1?2.8,25.7?3.5 vs 47.4?3.6,49.8?4.5,P0.05).Compared with the control group,the number and positive expression of AchE positive neuron in intestinal myenteric plexus decreased in small intestine and large intestine in intestinal operation group and intestine massage group(small intestine 43.0?3.0,52.2?3.3 vs 65.3?3.9,P

Objective To explore the nervous mechanism of intestinal function disorder after intestine congestion through observing the changes of acetylcholinesterase (AchE) neuron and nitric oxide synthase neuron (NOS) expression in nervous system of rat intestinal tract. Methods Sprague Dawley rats were divided into experimental groups (intestine congestion 20min and 60min group) and the control group. Then the spreading specimens of intestinal myen-teric plexus of ileums were collected and stained by AchE and nicotinamide-adenine dinucleotide phosphate-D (NADPH-d) histochemistry, to observe and compare the density of distribution and staining of AchE and NOS positive neurons. Result Compared to the control group, the number and positive expression of AchE positive neuron in intestinal myen-teric plexus of ileums in the experimental group rats decreased (P

Objective To study the effect of early mechanical ventilation in treatment of patients with severe acute pancreatitis(SAP).Methods Fifty-two patients with SAP admitted in the First People's Hospital of Zhaoqing from January 2010 to January 2015 were randomly allocated into two groups (n =26),early mechanical ventilation group(observation group) and conventional mechanical ventilation group(control group).Patients in the observation group treated with early lung protective ventilation when PaO2 ＜ 13.3kPa.Patients in the control group treated without mechanical ventilation untill PaO2 ＜ 8kPa.The symptoms,the extent of inflammatory reaction,the severity of lung lesions and the mortality of two groups were compared through monitoring vital signs,abdominal circumference,APACHE Ⅱ score,bladder pressure,oxygenation index (PaO2/FiO2),C reactive protein (CRP),procalcitonin (PCT),hospital stay and mortality.Results No statistically significant differences in the APACHE Ⅱ score,bladder pressure,oxygenation index,CRP and PCT in two groups before treatment were observed(P ＞ 0.05).The APACHE Ⅱ score (12.8 ± 7.6) points,bladder pressure (14.9± 7.9) cmH2O,CRP (48.8 ± 30.1) rmg/L,PCT (1.25 ± 0.55) μg/L,mortality (3.84％) of the observation group after treatment were significantly lower than those of the control group (t =2.057,2.091,3.252,2.697,x2 =4.305,all P ＜ 0.05),while the oxygenation index in the observation group [(300.0 ± 34.9) mmHg] was significantly higher than that in the control group [(278.1 ± 32.8) mmHg],the difference of the two groups was statistically significant (t =3.322,P ＜ 0.05).Conclusion Early lung protective ventilation is safe and effective for treatment of the patients with SAP.

Objective To explore the risk factors of initial surgery and postoperative complications of Crohn's disease (CD).Methods The retrospective case-control study was conducted.The clinical data of 227 patients with CD who were admitted to the Cangzhou Central Hospital from April 2011 to July 2015 were collected.Treatment principles included reducing the clinical symptoms,promoting healing of intestinal mucosa under endoscopy,delaying CD progression and preventing intestinal exhaustion and related complications.The medication was performed in the early period.The resection of partial intestines was applied to patients if there was poor effect of medication or combined with intestinal obstruction,intestinal fistula,digestive tract perforation,abdominal abscess and complex anal fistula.Observation indicators:(1) treatment situation,(2) follow-up situation,(3) related factors analysis affecting initial surgery of patients with CD,(4) related factors analysis affecting postoperative complications of patients after initial surgery for CD.Follow-up using regular telephone interview and outpatient examination was performed up to May 2016.Follow-up included the wound infection,abdominal abscess,intestinal obstruction,anastomotic fistula and pulmonary infection.Measurement data with normal distribution were represented as-x ± s and comparison between groups was analyzed using the t test.Count data were represented as the proportion and analyzed by the chi-square test.The univariate analysis was done using the chi-square test and Kruskal-Wallis test,and multivariate analysis was done using the Logistic regression model.Results (1) Treatment situation:of 227 patients,68 underwent initial surgery and 159 didn't undergo surgery.The duration from diagnosis to initial surgery in 68 patients was (4.7 ± 2.5) months.Of 68 patients with surgery,28 received the emergency surgery and 40 received the selective surgery.Operation time and volume of intraoperative blood loss were (175 ±44) minutes and (285 ± 110) mL,respectively.The side-to-side anastomosis was conducted in 47 patients and non-side-to-side anastomosis in 21 patients.Other 159 patients without surgery received the medication of mesalazine,hydrocortisone,methotrexate and infliximab.(2) Follow-up situation:68 patients with initial surgery were followed up for 5-61 months,and 22 had postoperative complications.Of 9 patients with anastomotic fistula,6 had enterocutaneous fistula (5 patients with enterocutaneous fistula were improved by selective surgery,and the other patient was progress to acute diffuse peritonitis and then was improved by peritoneal lavage,adequate drainage and nutritional support therapy after emergency surgery).Three patients with anastomotic abscess were improved by adequate drainage.Six patients with secondary intestinal obstruction were improved by conservative treatment.Three patients with abdominal abscess were improved after antiinflammatory treatment and adequate drainage.Two patients with wound infection were improved by regular dressing change.Two patients with pulmonary infection were improved by anti-inflammatory and phlegm conservative treatment.(3) The related factors analysis affecting initial surgery of patients with CD.The results of univariate analysis showed that age of diagnosis,smoking history and behavior of disease were the related factors affecting initial surgery of patients with CD (Z =-2.120,x2 =5.082,50.512,P＜ 0.05).The results of multivariate analysis showed that A3 of age of diagnosis,B2 and B3 of pattern of disease were the independent risk factors affecting initial surgery of patients with CD [OR =15.624,10.535,28.509,95％ confidence interval (CI):4.856-29.375,3.609-17.637,8.526-79.228,P ＜ 0.05].(4) The related factors analysis affecting postoperative complications of patients after initial surgery for CD.The results of univariate analysis showed that preoperative levels of albumin (Alb) and hemoglobin (Hb),emergency surgery,operation time and anastomotic method were the related factors affecting postoperative complications of patients after initial surgery for CD (x2 =10.757,7.639,6.773,4.309,16.346,P ＜ 0.05).The results of multivariate analysis showed that preoperative Alb≤28 g/L,Hb≤ 100 g/L,emergency surgery and non-side-to-side anastomosis were the independent risk factors affecting postoperative complications of patients after initial surgery for CD (OR =9.592,8.849,6.538,12.645,95％CI:2.209-25.235,2.034-24.773,1.846-15.893,3.935-38.873,P ＜ 0.05).Conclusions The age of diagnosis ＞ 40 years,B2 and B3 of CD are high risk group of initial surgery.The poor preoperative nutritional status,emergency surgery and non-side-to-side anastomosis are independent risk factors affecting postoperative complications of patients after initial surgery for CD.

Aim To study the effect of different doses of l-Tetrahydropalmatine( l-THP) on morphine-induced conditioned place preference(CPP) and observe whether l-THP itself induces CPP.Methods ①♂SD rats were administered with morphine (5.00 mg?kg -1 ,sc) or saline and trained for 8 days;on d 9,the rats were tested CPP with no treatment or 40 min after they were given different doses of l-THP(1.25～5.00 mg?kg -1,ip) to observe the effect of l-THP on morphine-induced CPP;② With daily injection of l-THP (ip) at different doses,effect on the extinguishment of morphine-induced CPP was tested weekly; ③ Normal saline (NS) or l-THP (1.25～5.00 mg?kg -1 , ip) was used as a training drug to test whether l-THP could induce CPP in the rats. Results 5.00 mg?kg -1 morphine (sc) induced CPP; l-THP of 2.50 mg?kg -1 and 5.00 mg?kg -1 administered prior to the testing reduced the expression of morphine-induced CPP significantly (P

Objective To observe the effects of CO2 pneumoperitoneum on the enteric motor function and acetylcholine esterase(AchE) neuron and nitric oxide synthase(NOS) neuron in the enteric nervous system,and explore the neuromechanism of the CO2 pneumoperitoneum on renteric motor function.Methods Thirty-six Sprague Dawley rats were randomly divided into experiment group(n=24) and control group(n=12).The experiment group was divided into two subgroups namely pneumoperitoneum 30min group and pneumoperitoneum 60min group(12 each) based on the maintenance time of pneumoperitoneum.Rats in each group were gavaged with medicinal carbon powder,and then the transmission of carbon powder in small intestine was determined.The spreading specimens of intestinal myenteric plexus of small intestine were prepared and the stained AchE and NOS neurons were observed and compared.Results The propellant velocity of carbon powder was slower in pneumoperitoneum 60min group than that in pneumoperitoneum 30min group and control group(28.55%?3.45% vs 45.90%?6.30%,48.25%?5.28%,P0.05).The number of positive expression of AchE neurons in intestinal myenteric plexus decreased in pneumoperitoneum 60min group compared with that in pneumoperitoneum 30min group and control group(48.00?3.16 vs 58.82?4.62,61.83?4.17,P0.05).The number of positive expression of NOS neurons in intestinal myenteric plexus increased in pneumoperitoneum 60min group compared with that in pneumoperitoneum 30min group and control group(42.17?4.45 vs 32.50?4.34,30.83?3.6,P0.05).Conclusions Prolonged CO2 pneumoperitoneum can affect or damage cholinergic neurons and nitroxidergic neurons in the enteric nervous system to some extent,and it may be the underlying mechanism of the intestinal motor dysfunction after operation.

OBJECTIVE To discuss the efficacy and safety of Onyx embolization for the treatment of maxillofacial arteriovenous malformation(mAVMs). METHODS Between February 2013 to May 2014, 16 patients with mAVMs received embolotherapy in our department. Eight cases' mAVMs located in mandibular region, 5 cases located in the maxillary region and the other 3 cases located near the orbital region. Embolotherapy with Onyx was carried out in all patients and all the patients were followed-up. The effect of embolization was evaluated according to the deformity arteriolar blood flow. RESULTS After the embolization, angiograpy showed that complete occlusion of mAVMs was achieved in 3 cases, 50%-90%occlusion in 10 cases, <50% occlusion in 3 cases, and the overall response rate was 81.25% (13/16). After operation, temporary decreased vision was obtained in one patient and recovered after 20 days, no permanent visual abnormality was found in all of the cases. Complications as distending pain, fever disappeared in 13 patients, improved in 2 patients and became worse in one patient. There was no case of skin necrosis occurred. Follow-up for 6 months after treatment, the deformity arteriolar blood flow larger than before was found in 2 cases and the others were stable. CONCLUSION Onyx embolization for the treatment of maxillofacial arteriovenous malformation is a safe and effective method, the short term curative effect has been confirmed while the long term curative effect should be further evaluated.
