Objective: By observing the effects of electroacupuncture (EA) on the apoptosis of conjunctival cells of rabbits with dry eye syndrome (DES) and the expressions of apoptosis-related proteins Caspase-3, Fas and Bcl-2, to discuss the mechanism of EA in the treatment of DES from the perspective of cell apoptosis. Methods: Male New Zealand rabbits were randomly divided into a normal group (NG), a model group (MG), an EA group (EAG) and a sham EA group (SEAG). DES rabbit model was developed by eye drop of 0.1％ benzalkonium chloride. The rabbit tear secretion and tear film break-up time (BUT) were measured; terminal deoxynucleotidyl transferase- mediated dUTP nick end labeling (TUNEL) assay was used to detect the apoptosis of conjunctival cells; the expressions of Caspase-3, Fas and Bcl-2 proteins in conjunctival cells were detected by immunohistochemistry. Results: Compared with the NG, the rabbit tear secretion decreased and the BUT was shortened in the MG (both P<0.01); compared with the MG and the SEAG, the rabbit tear secretion increased and the BUT was prolonged in the EAG (all P<0.05). Compared with the NG, the apoptosis of rabbit conjunctival cells increased (P<0.01), the expressions of Caspase-3 and Fas proteins increased (both P<0.05), and the expression of Bcl-2 protein decreased (P<0.01) in the MG; compared with the MG and the SEAG, the apoptosis of rabbit conjunctival cells decreased (both P<0.01), the expressions of Caspase-3 and Fas proteins decreased (all P<0.05), and the expression of Bcl-2 protein increased (both P<0.01) in the EAG. Conclusion: EA can inhibit the apoptosis of rabbit conjunctival cells, down-regulate the expressions of apoptosis-related proteins Caspase-3 and Fas, and up-regulate the expression of Bcl-2 protein, which may be one of the mechanisms of EA in treatment of DES.

OBJECTIVETo investigate the clinical results of scapula fractures with lateral incision combined with bridge internal fixation system.

METHODSFrom October 2012 to December 2016, 20 cases of scapular fractures were treated through the lateral incision combined with bridge fixation system, including 15 males and 5 females, with an average age of 31.6 years old(ranged, 21 to 52 years old). Fourteen cases were scapular body fracture, 10 were scapular neck fracture, 6 were scapular fracture, 1 was acromion fracture, 1 was coracoid fracture, 4 were the glenoid rim fracture, 3 were the glenoid fossa fracture. The operation time ranged from 4 to 15 d after injury with an average of 10 d.

RESULTSAll 20 cases were followed up for 3 to 24 months with an average of 15 months. Wound infection occurred in 2 cases after operation, and was healed after wound debridement and change dressing; no osteomyelitis, iatrogenic nerve injury, breakage of internal fixation, fracture displacement, joint stiffness occurred. Callus growth was observed at the fracture site 3 months after operation, the fracture healing time was 4 to 7 months, fracture healing was good without delayed union or malunion. According to Hardegger shoulder score, the results were excellent in 12 cases, good in 6 cases, moderate in 2 cases.

CONCLUSIONSLateral incision approach combined with bridge internal fixation system for scapula fractures has the advantages of easy operation, revealed clearly, and the incision can be arbitrary to extend on both sides, to provide favorable conditions for the reduction and fixation of fracture. Bridge combined internal fixation system has the advantages of flexible operation, reliable fixation strength, is a good choice for treatment of scapula fracture.

To establish a method for determining the contents of six alkaloids (jatrorrhizine hydrochloride, columbamine hydrochloride, epiberberine hydrochloride, coptisine hydrochloride, palmatine hydrochloride, berberine hydrochloride) in six types of Coptidis Rhizoma pieces (crude pieces, ginger juice stir-fried pieces, vinegar stir-fried pieces, wine steamed pieces, wine stir-fried pieces, evodiae juice stir-fried pieces) by RP-HPLC, and explore the relationship with the curative effect of traditional Chinese medicine (TCM) and pharmacodynamics results. The chromatographic column was Welch XtimateTM C₁₈ (4.6 mm×250 mm, 5 μm), with 0.1% triethylamine solution (adjust pH at 10 with ammonium bicarbonate and ammonia) as mobile phase A and acetonitrile as mobile phase B for gradient elution (0-15 min, 10%-25%B; 15-25 min, 25%-30%B; 25-40 min, 30%-45%B) at a rate of 1.0 mL•min⁻¹. The column temperature was set at 30 ℃, and the wavelength was set at 270 nm. The six alkaloids showed a good linear relationship within the range of 0.85-16.96 mg•L⁻¹ (r=0.999 7), 1.25-24.96 mg•L⁻¹ (r=0.999 9), 2.05-40.96 mg•L⁻¹ (r=0.999 9), 3.65-72.96 mg•L⁻¹ (r=0.999 9), 2.88-57.60 mg•L⁻¹ (r=0.999 8), and 13.25-264.96 mg•L⁻¹ (r=0.999 6) respectively. The average recoveries (n=9) of the six alkaloids were 102.4% (RSD 1.2%), 101.8% (RSD 1.3%), 100.3% (RSD 1.8%), 100.7%(RSD 1.8%), 101.2% (RSD 1.5%) and 97.90% (RSD 2.0%) respectively, and their average contents were 3.55, 4.49, 9.12, 19.17, 15.69, 62.56 mg•g⁻¹, respectively. This determination method was accurate and repeatable, which could be used for the content determination in six types of Coptidis Rhizoma pieces. Data analysis on contents determination and preliminary pharmacodynamics results was conducted by using principal component analysis (PCA) and hierarchical clustering analysis (HCA). The analysis results showed that three types of Coptidis Rhizoma pieces (wine steamed pieces, wine stir-fried pieces, and evodiae juice stir-fried pieces) had significant differences with crude pieces, and the wine steamed Coptidis Rhizoma pieces showed most difference with crude pieces especially, mainly related to triglyceride (TG) and fasting blood glucose levels (FBG) in serum. In addition, columbamine hydrochloride was most affected among the six alkaloids. Those three types of Coptidis Rhizoma pieces (wine steamed pieces, wine stir-fried pieces, and evodiae juice stir-fried pieces), had more advantages for "anti-diabetes" in TCM clinical application, especially in the treatment of diabetic hyperlipidemia.

OBJECTIVETo evaluate the feasibility and effectiveness of placement of nasojejunal feeding tube and nasojejunal nutrition feeding in children with acute pancreatitis.

METHODTwenty-two patients (of whom 13 had severe acute pancreatitis and 9 acute mild pancreatitis) who needed nutritional intervention were selected. They were from Department of Gastroenterology and Surgery during the years 2009 - 2012, and they were at high nutritional risk after STONGkid nutrition risk screening. The average age of them was 5 - 15 years (9.1 years ± 2.8 years). Assisted by endoscopy, the nasojejunal feeding tube was placed in 22 of 24 patients (in 2 cases of recurrent pancreatitis the tubes were placed again after extubation). Besides the use of regular fasting, antacids, inhibitors of trypsin secretion, and anti-infective treatment, 23 cases of all children got nasojejunal nutrition treatment as well. The outcome measures included the success rate, complications of endoscope-assisted nasojejunal tube placement. The children's tolerance and nutrition indicators (weight, blood lymphocytes count, erythrocytes count, serum albumin, serum creatinine, blood urea nitrogen) were observed before and after enteral nutrition therapy.

RESULTMalnutrition evaluation was done 24 times before treatment among 22 patients, incidence of malnutrition was 33% in 22 cases. Placement of nasojejunal tube placement was attempted for a total of 24 times and was successful on first placement in 22 cases, in two cases the placement was successful on the second placement, so the success rate of the first attempt for placement was 92%. No significant complications were observed in any of the cases. Twenty-three of 24 cases were given standardized enteral nutrition (one case was not given enteral nutrition therapy but underwent ERCP due to obstructive jaundice). Twenty-two of 23 cases could tolerate enteral nutrition well, only 1 case was unable to tolerate enteral nutrition due to the pancreas schizophrenia, paralytic ileus. The treatment of jejunal feeding success rate was 96%. The feeding duration was 2 - 74 d (27.0 d ± 18.3 d). The adverse reactions include plugging of the tube in two cases, constipation in two cases, five cases had abdominal pain, diarrhea in 2 cases, vomiting in 2 cases and 1 case of jejunum retention. No case had nasopharynx ulcers, gastrointestinal perforation, gastrointestinal bleeding, re-feeding syndrome and infection etc. Blood erythrocytes count, serum creatinine, blood urea nitrogen were not significantly changed. Twenty of 23 cases were cured, 2 cases were improved and 1 case was unchanged.

CONCLUSIONEndoscope-assisted nasojejunal tube placement for children with acute pancreatitis is safe and feasible. Nasojejunal nutrition therapy is effective for acute pancreatitis patients who are at severe nutritional risk, especially for the improvement of the nutritional status of children.

BACKGROUNDLaparoscopic dismembered pyeloplasty is technically feasible for ureteropelvic junction (UPJ) obstruction although it is still challenged by its technical difficulty and time-consuming. In this study, we compared the initial results of retroperitoneal laparoscopic pyeloplasty versus a combined laparoscopic dissection and open reconstruction through a small incision in the treatment of UPJ obstruction.

METHODSSixty-four patients with primary UPJ obstruction underwent pyeloplasty: 32 patients underwent laparoscopic procedure and 32 patients underwent open assisted laparoscopic surgery including two steps, ie, laparoscopic dissection of the UPJ transperitoneally and then pyeloplasty via an extended small incision. The demographic data and intraoperative, postoperative and follow-up conditions of patients were compared between the two groups.

RESULTSPreoperative data were comparable in the patients of the two groups. The operative time was shorter (60.9 minutes vs 157.7 minutes, P < 0.0001) and the complication rate was lower (9.4% vs 31.3%, P < 0.05) in the open assisted group than in the laparoscopic group. The estimated blood loss (42.3 ml vs 47.8 ml), time to have normal diet (37.6 hours vs 33.8 hours), and hospital stay (6.7 days vs 6.2 days) were equivalent. The operative success rate was 97% for the open assisted group and 91% for the laparoscopic group.

CONCLUSIONSThe procedure of combined small incision with laparoscopy for UPJ obstruction is technically easy, and the results are promising. It can be used as an alternative to conventional procedures.

OBJECTIVETo explore the effective management to prevent anastomotic leakage and intestinal ischemia after esophageal replacement with colon(ERC).

METHODSClinical data of 572 cases received ERC from March 1966 to March 2006 were analyzed retrospectively.

RESULTSMost of patients received ERC were diagnosed as esophageal cancer and esophageal stenosis(92.5%). 55.6% of cases underwent esophageal reconstruction and 44.4% of cases underwent esophageal bypass. During ERC procedure, the colon interposition graft length should be 3-4 cm longer than expectation; good blood supply was maintained; the lifted passage was unobstructed, and the physiological peristalsis direction was kept. The incidence of anastomotic leakage was analyzed among different periods, which were 14.2%, 13.5%, and 5.6% during 1966-1975, 1976-1995 and 1996-2006 respectively(P<0.05). No intestinal ischemia was observed in all the patients.

CONCLUSIONSWhen performing ERC, the main preventional managements of anastomotic leakage and intestinal ischemia are fully blood supply maintenance and intercepting enough length of the colon graft. Ensuring unobstructed passage is good for survival of the colon graft. Correct physiological peristalsis direction of colon interposition is beneficial to the healing of the anastomosis.
