Objective To explore the liver transplantation in end stage liver disease with portal vein thrombosis (PVT). Methods Computer Tomography and color Doppler examinations were performed on the recipients to be subject to liver transplantation. Four male cases were found having PVT, received orthotopic liver transplantation and thrombectomy. Cell Saver auto transfusion blood and venous by-pass was also conventionally used. By reason of one case with residual thrombosis, a catheter with heparin cap was inserted into the branch of superior mesentery vein, followed by perfusion of urokinase for thrombus dissolution. Anti-coagulation treatments with low molecule heparin and Prostaglandtin E1 after operation were carried on in all of the patients. Results Surgical management of PVT were successful only one time in 3 patients. One patient with PVT extending over the entrance of spleen vein and left and right portal vein branches had portal vein residual thrombosis postoperation. After dissolution and anti-coagulation for 28 days, the residual thrombus disappeared. One cured patient with PVT died 48 days after operation from lung infection due to multiocular effusion resulting from chest cavity bleeding after pleuracentesis, and other 3 patients were cured in 2 months. Conclusion The PVT is not an absolute contraindication to liver transplantation; Thrombectomy combined with thrombus dissolution and anticoagulation can cure PVT; Prevention of bleedings in the patients with PVT is very importance postoperation.

The method of preparation of a Milk Substitute, formula 5410, and its nutritive value on rats have been reported in previous communications. Further tests of its nutritive effect were made by feeding a group of 100 infants including 4 premature and 10 undernourished. Another group of 43 infants fed with human breast milk or cow's milk were observed during the same period as controls. Among the infants of the two groups there were 6 pairs of twins; one of each pair was fed with the Milk Substitute and the other with human or cow's milk. Great majority of the infants were cared by their own mothers whose cooperation had been secured, while the rest of the infants (10%) were kept in our nursery.The Milk Substitute feeding was started with infants between half and six months of age, with an average age of three months. Observations were continued until they all reached one year old. Fish liver oil and ascorbic acid were supplied to infants of both the experimental and the control groups. Vegetable soup and fruit juice were given to the infants before five months of age. Then various kinds of other foods, including rice porridge, wheat flour nudols, bread, crackers, mashed meat and vegetable and egg yolk were individually supplemented furnishing not more than 1/3 of the total caloric intake, (at the age of one year), as the family income permitted.The appetite of the experimental infants was normal. There was no digestive disturbances and abnormal frequency and appearance of the stool. The average daily caloric intake was similar to those recorded in the literature.The body weight and height of the babies in the experimental group fell well within the normal range. The average initial body weight and height of the infants in the experimental group were somewhat lower than those of the control; however, the height reached .that of the control at the age of 7 months, and the weight at about 11 months. The red blood cell counts and the hemoglobin value of the blood were normal.Values of blood alkaline phosphatase activity higher than 15 Bodansky units were shown in 20 babies of the experimental group (27%) and 8 babies of the control group (23%) at the beginning of the observation; only 4 babies in the experimental group were found abnormal high blood alkaline phosphatase value at the end. At the beginning, 3 cases of rickets and 3 cases of suspected rickets were indicated by the radiograph of the wrist bones of the babies in the experimental group, and only one suspected ricket in the control group were observed; and they all became normal at the end of the experiment. Besides, there were no other signs of any nutritional deficiency among all the infants.

Objective To investigate the reversal of the multidrug resistant gene mdr1 in vivo by antisense oligodeoxynucleotide (ASODN) on the basis of study in vitro. Methods The cultured drug-resistant human hepatocellular carcinoma cells were injected under the skin of axilla to establish the tumor model of nude mice. mdr1 ASODN accompanied by Lipofectamine were injected locally and ADM was injected intraperitoneally. Control 1 and control 2 were locally injected by Lipofectamine and normal saline separately, and ADM was also injected intraperitoneally. Results As time went on the tumor size increased and from the 5th day on alterations were marked, tumor size in different time phase showed marked difference to the prior time phase with significant difference (P 0.05). The results suggested that SODN and Lipofectamine showed no marked effect on tumor growth of nude mice and ASODN had marked inhibition effect on tumor growth.Conclusion mdr1 ASODN can also reverse multidrug resistance of drug-resistant human hepatocellular carcinoma cells in vivo. After the treatment the tumor’s growth in nude mice will slow down in a range of time.

OBJECTIVE To establish a quantitative analysis of multi-components by single marker （QAMS） method based on a variety of internal reference substances for the content determination of 6 components in Jinlian qingre granules， such as mangiferin， 2″-O-β-L-galactopyranosylorientin， orientin， veratric acid， vitexin， harpagoside. METHODS The determination was performed on Agilent Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution （gradient elution） at the flow rate of 1 mL/min. The column temperature was 30 ℃， and the detection wavelength was set at 270 nm. Taking orientin， vitexin and 2″-O-β-L-galactopyranosylorientin as internal references， the relative correction factors （RCF） of the other 5 components to be determined and internal substances were determined by QAMS. The contents of 6 components in 21 batches of Jinlian qingre granules were calculated and then compared with the results of the external standard method. RESULTS The contents of mangiferin， 2″-O-β-L-galactopyranosylorientin， orientin， veratric acid， vitexin and harpagoside in 21 batches of samples were determined by QAMS in the range of 0.234-0.516， 1.804-2.270， 2.143-2.606， 0.190-0.223， 0.594-0.782， 0.080-0.152 mg/g； the contents of them determined by external standard method were 0.235-0.523， 1.798-2.265， 2.137-2.599， 0.190-0.224， 0.597-0.786， 0.077-0.151 mg/g， respectively. The percentage difference between the results measured by the two methods should not exceed 4.00%. CONCLUSIONS QAMS has been constructed for the simultaneous determination of 6 components in Jinlian qingre granules based on a variety of internal reference substances. The results obtained by this method are not significantly different from those obtained by the external standard method， and can be used for the quality control of Jinlian qingre granules.

OBJECTIVE: To explore the safety, feasibility and short-term efficacy of intracavitary uncut Roux-en-Y (URY) anastomosis in digestive tract reconstruction following laparoscopic total gastrectomy (LTG). METHODS: From November 2015 to January 2018, 67 gastric cancer patients underwent intracavitary URY following LTG to reconstruct the digestive tract at Oncological Surgery Department of Fujian Provincial Hospital. There were 41 males and 26 females with age of 50 to 81 (61.9±7.4) years and body mass index (BMI) of (23.4±3.2) kg/m². Among 67 patients, 19 were gastric cardia carcinomas, 33 were gastric body carcinomas, and 15 were gastric fundus carcinomas; tumor size was (3.4±2.3) cm; 22 were Borrmann type I, 15 were type II, 21 were type III, and 19 were type IV; 29 were highly or moderately differentiated adenocarcinoma, 23 were lowly differentiated adenocarcinoma, and 15 were signet-ring cell carcinoma. After conventional laparoscopic D2 radical gastrectomy, the duodenum was closed and dissociated at 2 cm below the pyloric ring using the Echelon-flex endoscopic articulated linear Endo-GIA stapler, and the esophagus was dissociated above the esophagogastric junction (EGJ).URY and digestive tract reconstruction were performed under the direct vision of laparoscope: (1) Side-to-side esophagojejunostomy: An incision of 0.5 cm was made in the left lower edge of the esophageal closed end; jejunum about 25 cm distal away from the Treitz ligament was elevated to the lower end of esophagus; another incision of 0.5 cm was made in the contralateral of mesenteric side; both arms of the linear Endo-GIA stapler were inserted into the windows opened through esophagus and jejunum respectively to complete side-to-side anastomosis. The common opening of esophagus and jejunum was closed to complete esophagojejunostomy, forming the chyme outflow tract. (2) Side-to-side Braun jejunojejunostomy: Incisions of 0.5 cm were made in the proximal jejunum about 10 cm away from the esophagojejunal anastomosis and 35-40 cm away from the contralateral of mesenteric side of distal jejunum respectively for proximal-distal side-to-side jejunojejunostomy. The common opening was closed to form the biliopancreatic duodenal juice outflow tract. (3) Closure of the input loop jejunum in the esophagojejunal anastomosis: The input loop jejunum 2-3 cm away from the esophagojejunal anastomosis was closed using the non-blade linear stapler (ATS45NK), and the biliopancreatic duodenal juice reflux was blocked. Clinical data of these patients were collected for retrospective case series study. Surgical and digestive tract functional recovery, perioperative complications, as well as postoperative nutritional status were observed. Moreover, related indexes, such as anastomosis function and tumor recurrence were evaluated through endoscopic and imaging examinations during postoperative follows-up. RESULTS: All the 67 patients completed the surgery successfully. The mean operative time was (259.4±38.5) minutes, digestive tract reconstruction time was (38.2±13.2) minutes, intraoperative blood loss was (73.4±38.4) ml, and number of harvested lymph node was 36.2±14.2. The mean distance from upper resection margin to upper tumor edge was (3.3±1.2) cm, distance from upper resection margin to dentate line was (1.2±0.7) cm, and 1 case had positive upper incisal margin, which became negative after the second resection. Moreover, the average length of the auxiliary incision was (3.2±0.4) cm. The mean postoperative intestinal exhaust time was (52.8±26.4) hours, time to liquid diet was (64.8±28.8) hours, and postoperative hospital stay was (8.4±2.5) days. The morbidity of postoperative complication was 10.4%(7/67). Among these 7 cases, 4 cases were grade IIIa of Clavien-Dindo classification, including 2 with esophagojejunal anastomosis leakage, 1 with duodenal stump leakage, and 1 with abdominal infection, and all these patients were recovered after conservative treatment. All the 67 patients were followed up. The mean nutrition index 12 months after surgery was 53.4±4.2, diameter of esophagojejunal anastomosis was (3.9±0.6) cm, the incidence of Roux-en-Y stasis syndrome was 3.0% (2/67), and the incidence of reflux esophagitis was 4.5% (3/67). No patient had recanalization of the closed input loop of esophagojejunal anastomosis, anastomotic stenosis, obstruction, or tumor recurrence at anastomosis. CONCLUSION Intracavitary URY anastomosis following LTG for digestive tract reconstruction is safe and feasible, leading to fast postoperative recovery of digestive tract function and favorable short-term efficacy.

As one of the pathogenic mechanisms contained in The Inner Canon of Yellow Emperor （《黄帝内经》）， “disease with latent pathogen induced by a new pathogen” means that the induced new pathogen resulted to a combination of the latent previous pathogen and the new pathogen， which caused the disease. Based on this， it is believed that the change of “nodule-cancer transformation” of pulmonary nodules is actually based on the deficiency of original qi， and the new pathogen induces the latent pathogens like phlegm coagulation， qi stagnation， blood stasis， toxicity， so healthy qi can not drive the pathogens out， and the long-time detention generated into cancerous turbidity， and deve-loped into cancerous tumour at the end. Therefore， based on the three-stage treatment of unformed cancer， dense cancerous toxin， and developed cancer， the clinical practice applied six methods of clearing， expelling， dissipating， tonifying， harmonizing， and transforming， taking into account both the manifestation and root cause， moving the treatment window of pulmonary nodules forward， attacking the pathogens when the toxin was not yet overbearing， supporting the healthy qi before declining， delaying the process of nodules-cancer transformation， and providing ideas for the prevention and treatment of pulmonary nodules “nodule-cancer transformation” in traditional Chinese medicine.
