Objective To investigate the effects of low molecular weight heparin (LMWH) on severe acute pancreatitis(SAP). Methods Retrospective analysis was made on the clinical features and therapeutic effect on the routine treatment (RT) group in 48 cases and LMWH treatment(LT) group in 31 cases. Results 28 (90.3%) out of 31 cases were cured while 3 (9.7%) died in LT group. 35(72.9%) out of 48 cases were cured whereas 15 (27.1%) died in RT group. The complications occurring in LT group (32.3%,10 patients 18 times ) was significantly lower than that in the RT group (62.5%,30 patients 59 times)(P

Objective To explore the treatment effects of low molecular weight heparine (LMWH) on severe acute pancreatitis (SAP). Methods Random analysis were made on the clinical features and therapeutic effect on the control treatment group (CT) in 65 cases and LMWH treatment group (LT) in 77 cases.Results 70(90 9%) cases were cured in LT group,and 48(73 8%) cases were cured in CT group. The incidence of complications in the LT group (28 6%, 22patients 45 times) was significantly lower than that in the CT group (60%,39patients 79 times)(P

Objective To investigate the intervention of chemokine receptor 4(CXCR4) antagonist AMD3100 in lung tissues of rats during pulmonary oxygen intoxication.Methods Forty SD rats were randomly divided into 4 groups:normal pressure air PBS group, normal pressure air antagonist group , oxygen exposure PBS group and oxygen exposure antagonist group, each consisting of 10 animals.The last two groups were compressed to 0.23 MPa at an exponential rate of 0.1 MPa/min by pure oxygen.Pathological changes of lung tissues were observed by hematoxylin eosin stain.Changes in TNF-αand IL-1βexpression levels in the lung tissues of rats were detected by ELISA.Changes in CXCR4 expression levels were ob-served by Western blotting.Results Pathological examination indicated that edema and hemorrhage in the alveolar and pulmonary interstitial tissue of oxygen exposure antagonist group were lighter than in oxygen exposure PBS group.The levels of TNF-α, IL-1βand cleaved-caspase-3 in the lung tissues of the oxygen exposure antagonist group were lower than in oxy-gen exposure PBS group.Conclusion Blocking CXCR4 with AMD3100 can effectively alleviate lung injury during pulmo-nary oxygen intoxication.

OBJECTIVE: To improve diagnosis and treatment level of esophageal foreign bodies of button cell. METHOD: Reported 4 clinical cases of esophageal foreign bodies of button cell. RESULT: Because of different diagnosis time and different surgical time, one case died and the other were cured. CONCLUSION Esophageal foreign bodies of button cell has been reported rarely before. Because button cell is caustically basic, drastically dangerous, it should be emphasized clinically. The key point to cure this disease is diagnosing timely and operating a surgery as soon as possible.

OBJECTIVE: To improve diagnosis and treatment level of foreign body ingestion of button cell in children. METHOD: Among the 14 cases with foreign bodies ingestion of button cell, 6 cases in esophageal, 7 cases in stomach and lower gastrointestinal tract, 1 case with multiple foreign bodies both in esophagus and stomach. Seven cases in stomach and lower gastrointestinal tract were closely observed without special treatment, 6 cases in esophageal, underwent esophagoscopy and removal of foreign body under general anesthesia, 1 case with multiple foreign bodies in esophagus and stomach underwent esophagoscopy and electronic gastroscopy and then removal of foreign body. All patients had symptomatic treatments after removal of foreign body. The average age is 2 years and 1 month. RESULT: After the removal of button cell, Foreign bodies in stomach and lower gastrointestinal tract in 7 cases were all discharged spontaneously. For the 6 cases in esophagus, 4 cases were cured, 1 case had esophageal stricture, 1 cased died. 1 case with multiple foreign bodies in both esophagus and stomach was cured. CONCLUSION Esophageal foreign body has strong corrosiveness and would cause serious damages even to threaten children's life. It also may lead to esophageal stricture. The key point to cure this disease is to diagnose timely and to operate as soon as possible. Because neutralize of digestive juices and low probability of incarceration, with close observation, the foreign bodies of stomach and lower gastrointestinal tract can discharge spontaneously.

Objective Sarcandra glabra is a widely-used Chinese medicinal herb,but the wild germplasm resources were decreasing.In order to protect the germplasm resources,the genetic diversity and genetic relationship among the various provenances should be analyzed.Methods ISSR Molecular markers were used to analyze the genetic diversity of S.glabra collected from eight provenances.The genetic diversity,genetic distance,and cluster analysis were performed by Popgen32 software and UPCMA method.Results Ten screened polymorphic primers were used in ISSR-PCR and 111 bands were amplified,among them including 106 polymorphic bands that were about 95.50%.Genetic distance of eight different provenances were ranged from 0.034 7—0.185 0.The genetic diversity of S.glabra mainly came from the interior variation of every provenance,for Gst=0.340 3.Conclusion Provenances of S.glabra can be divided into two groups and based on the relationship of genetic distance and altitude,the provenances can be divieded as follows:correspondingly higher altitude group(800-900 m);correspondingly lower altitude group(250-300 m);middling altitude group(600 m).

Objective:To explore the clinical value of 16-slice spiral CT in diagnosing bony lacrimal passage fracture.Methods:16-slice spiral CT images of 65 patients,which were clinically proved as bony lacrimal passage fractures,were analyzed retro-spectively.Postprocessing of images was performed by GE AW 4.1.Multi planar reconstruction(MPR).The thin-thick axial images were compared with the MPR.Results:16-slice spiral CT showed clearly the fractures of lacrimal sac fossa and nasolac-rimal duct.All the 65 cases were compound fracture,most of which were naso-orbital-ethmoid fracture,including 45 cases of fractures of the frontal process of the maxilla,30 cases of the lacrimal bone fractures,40 cases of ethmoid bone fractures on the medial orbital wall,32 cases of nasal bone fractures,13 cases of the nasal process fractures of frontal bone,23 cases with naso-maxillary suture separations,17 cases with naso-frontal suture separations,20 cases with frontal-maxillary suture separations, 50 cases with lacrimo-maxillary suture separations,26 cases with internasal suture separations.There was no significant difference between the thin-thick axial images and the MPR in diagnosing bony lacrimal passage fracture.Conclusions:16-slice spiral CT can accurately display the location,extent and secondary changes of bony lacrimal passage fracture in detail.
