Objective To investigate the effectiveness and feasibility of laparoscopic splenic artery ligation in the treatment of hypersplenism and thrombocytopenia in children. Methods From August 2014 to December 2014, four children with hypersplenism and three children with ITP (idiopathic thrombocytopenic purpura) were treated in our hospital.Laparoscopic splenic artery ligation was performed in all the patients.During the operation, the gastric colon ligament was cut with an ultrasonic knife, and the gastric wall was suspended to expose the pancreas and the spleen.The splenic artery was ligated at the upper edge of pancreas closing to the splenic hilum.The splenic venous branches were dissected and ligated at the splenic hilum by using the Hem-o-lok, which leaded to an area of splenic infarction more than 50%. Results The laparoscopic splenic artery ligation was successfully performed in all the patients, without conversion to open surgery.The operative time was 120-150 min ( mean, 126 min) , and the intraoperative blood loss was 10-20 ml ( mean, 15 ml) .No patient underwent blood transfusion.The length of postoperative hospital stay varied from 4 to 11 days (mean, 6.6 days).The splenic length significantly decreased postoperatively [(13.6 ±2.6) cm vs.(15.1 ±1.7) cm, t=3.199, P=0.049], and so was the splenic thickness [(3.8 ±1.0) cm vs.(4.1 ±0.8) cm, t =3.703, P=0.034].Partial splenic infarction and decreased splenic blood flow were found in the 7 patients by postoperative ultrasound.After surgery, four children suffered from fever, which were 38.8 ℃, 39.0 ℃, 38.6 ℃, and 39.2 ℃, with the duration of fever of 2, 4, 8, and 5 days, respectively.All the patients were followed-up for 6 -10 months (mean, 8.4 months).The complete blood cell count was within normal range. Conclusion The laparoscopic splenic artery ligation is an effective treatment for hypersplenism and thrombocytopenia in children.

Objective To investigate curative effects of endoscopic sternocleidomastoid muscle amputation for the treatment of congenital muscular torticollis.Methods A total of 23 children with congenital muscular torticollis were treated in this department.Their age was 1 month ~ 12 years old(median,30 months).A 5 mm trocar was inserted through the right axilla along the cleavage lines.Under the endoscopic visualization,the sarcolemma on the inferior portion of the muscle was bluntly dissected and a subcutaneous space was established by CO_2 inflation at the pressure of 6 mm Hg.Another two 3 mm incisions were made along the cleavage lines at lower lateral part of the neck and the anterior chest wall for the introduction of curved forceps and electric knife,respectively.The sternocleidomastoid muscle was transected with electrocautery and the external fascia within which the sternocleidomastoid muscle resides was also adequately divided. Results The operation was successfully completed under endoscope in all the 23 children.The mean operation time was 51.2 min(range,(35~)135 min) and the intraoperative blood loss was

It is of great importance to emphasize the teachers and students to value the teaching work together. Importance should be attached to the advantage of subject of academy, to make the clinical practice closer to practical, which has a perfect effect and will benefit our work.

Continuously cropping obstacle restricts ginseng production and rational use of land resource severely, and autotoxicity is one of the most important factors. In our previous work, ginseng autotoxin degrading bacteria were isolated, in the present re- search, plate culturing method and traditional physiological and biochemical method were used to analyze biological indices and protective enzyme activities, in order to elucidate the mitigative effect of autotoxin degrading bacteria on autotoxicity of P. ginseng. Results indicated that, except for palmitic acid, autotoxicity of benzonic acid, diisobutyl phthalate, diisobutyl succinate, and 2,2-bis (4- hydroxyphenyl) propane on the growth of ginseng seeds was significantly alleviated after autotoxins degrading bacteria was inoculated, and which have no evident difference with control. Except for benzoic acid, enzyme activity of SOD, POD and CAT in other autotoxin degrading treatments decreased significantly. The present research showed that, microbial degradation could alleviate the autotoxicity of autotoxins on ginseng seeds effectively, and which will be helpful for the resolution of ginseng continuously cropping obstacle problem.

Objective To investigate the diagnosis and treatment of pulmonary tuberculosis in renal transplantation recipients.Method The clinical data of 8 renal transplantation recipients suffering from pulmonary tuberculosis infection were retrospectively analyzed.Result Fever,cough and expectoration were the most common symptoms,however,lacking typicality.Images of chest Xray and CT scan were various and couldn't verify TB infection from pneumonia.Seven of 8 cases were diagnosed through invasive methods,either bronchofibroscope or fiberthoracoscopy.Immunosuppressants were decreased in all cases.Three-drug regimens,including isoniazide,rifampicin and ethambutol or pyrazinarnide,were administrated as anti-tuberculosis chemotherapy.All the cases were cured,without episodes like acute rejection and liver function impairment.Conclusion Routine examinations are not sufficient to diagnose pulmonary tuberculosis in kidney transplantation recipients.While,invasive methods like bronchofibroscope and fiberthoracoscope are helpful.When diagnosed,patients should receive normative anti-tuberculosis treatment and immunosuppressive agents adjustment,which can benefit the prognosis of pulmonary tuberculosis in renal transplantation recipients.

Objective The Rex shunt has been used to treat children with extrahepatic portal hypertension by creating a venous bypass between the superior mesenteric vein and the left portal vein to circumvent the extrahepatic portal venous obstruction.This retrospective study aimed to analyse our results in the use of this novel approach.Methods 52 patients with cavernous transformation and obstructed main portal veins were treated by Rex shunts.Results The age of children was 1.4 ～ 12 year,the mean age was 3.7 years.The patients were followed up from 1.5 to 5 years.In 48 patients,there was no recurrence of gastrointestinal bleeding after surgery making an efficacy rate of 92.3％.In the recurrence group,the postoperative venous pressure in the superior mesenteric vein was (27.6 ± 3.2) cmH2O (1 cmH2O =0.098kPa) which was significantly higher than the non-recurrence group (23.5 ± 3.1)cmH2O.The difference between the pre-and post-Rex shunting was significantly lower in the recurrence group (5.7 ± 1.8)cmH2O than the non-recurrence group (11.7 ± 3.3) cmH2 O,P ＜ 0.05.Thus,a low reduction in postoperative pressure was an early manifestation of poor prognosis.Conclusions The Rex shunt was safe and efficacious.The degree of reduction in postoperative venous pressure in the superior mesenteric vein could be used to predict recurrence of gastrointestinal bleeding.

BACKGROUND:In the treatment of tibial plateau fractures, because of the variety of fracture, the complexity of anatomical changes, X-ray films or three-dimensional CT scan limited by two-dimensional plane, increases the difficulty in preoperative plan and surgical treatment. The application of three-dimensional (3D) printing technology has attracted attention in the department of orthopedics. OBJECTIVE:To explore the auxiliary role of 3D printing technique in preoperative plan and treatment for tibial plateau fractures. METHODS:Thirty patients with tibial plateau comminuted fractures were enroled in this study and divided into two groups: experimental and control groups, with 15 patients in each group. In the experimental group, patients underwent 3D CT scan, which was stored in DICOM format, and processed by Mimics software. Data were converted into STL format, entered 3D printer, and a 1:1 entity size of the fracture model was made, in accordance with repair plan of 3D fracture model. Operation time and intraoperative blood loss were compared between the two groups. At 12 months after treatment, their outcomes were assessed using Rasmussen evaluation criteria. RESULTS AND CONCLUSION: The 3D printing fracture models of 1:1 ratio identified fracture type and made a repair program before surgery in the experimental group. Operation time and intraoperative blood loss were significantly less in the experimental group than in the control group (P < 0.05). After surgery, patients were folowed up for 12 to 18 months. The healing time was 3-5 months, averagely 4.3 months. At 12 months after treatment, the Rasmussen evaluation criteria results showed that the excelent and good rate was significantly higher in the experimental group than in the control group (P < 0.05). These results suggest that the fracture model of 3D can help to make the operation plan. The treatment of tibial plateau fractures is more precise, personalized and visual.

OBJECTIVE: To select specific DNA aptamer for determining ketamine by FluMag-SELEX. METHODS: Based on magnetic beads with tosyl surface modification as solid carrier and ketamine as target, a random ssDNA library with total length of 78 bp in vitro was compounded. After 13 rounds screening, DNA cloning and sequencing were done. Primary and secondary, structures were analyzed. The affinity, specificity and Kd values of selected aptamer were measured by monitoring the fluorescence intensity. RESULTS: Two ssDNA aptamers (Apt#4 and Apt#8) were successfully selected with high and specific abilities to bind ketamine as target with Kd value of 0.59 and 0.66 μmol/L. The prediction of secondary structure was main stem-loop and G-tetramer. The stem was the basis of stability of aptamer's structure. And loop and G-tetramer was the key of specific binding of ketamine. CONCLUSION FluMag-SELEX can greatly improve the selection efficiency of the aptamer, obtain the ketamine-binding DNA aptamer, and develop a new method for rapid detection of ketamine.
