ObjectiveTo investigate the effects of platelet derived growth factor (PDGF) on brain cell apoptosis rate and serum neuron-specific enolase (NSE) concentration after hypoxic-ischemic brain damage (HIBD) in neonatal rats. MethodsForty-eight HIBD models of 7-day old neonatal Wistar rats were established and then divided into two groups randomly:PDGF group and normal saline control group (n =24 in each).Another 24 neonatal Wistar rats were taken into the sham operation group.The treatment group received intraperitoneal injection of PDGF-BB (50 ng/kg) once,while the other two groups received normal saline at the same time.In each group,rats were randomly sacrificed immediately at 12,24 and 72 hours after injection (n=8).The serum of rats were reserved for NSE concentration determination by enzyme linked immunosorbent assay,and the right brains of the sacrificed rats were used to prepare brain cell suspension for neurocyte apoptosis rate examination by flow cytometry.Mono-variate analysis and q-test were performed for statistical analysis. Results(1) The brain cell apoptotic rates of treatment group [ (6.09 ± 0.70)％,(9.67 ± 1.52) ％ and (14.15±1.52)％] and control group [(8.00± 1.10)％,(11.45±2.42)％ and (22.90±2.03) ％] were significantly increased compared to that of sham group [(2.11 ± 0.54)％,(2.34 ±0.46)％ and (2.21±0.49)％] at all time points (all P＜0.01 or ＜0.05),the apoptotic rate of treatment group was lower than that of control group (P＜0.01 or ＜0.05).Statistical differences were found among the three groups at 12,24 and 72 hours (F =39.01,66.60 and 194.20respectively; P＜0.01).(2) Serum NSE concentration was significantly increased in the treatment group [(8.43 ± 0.17) μg/L,(6.73 ± 0.16) μg/L and (6.12 ± 0.13) μg/L] and control group [(10.04±0.19) μg/L,(9.330.15) μg/L and (8.36 ± 0.16) μg/L] than in the sham group [(4.22±0.53) μg/L,(3.96±0.60) μg/L and (3.59±0.55) μg/L] at all time points,and it was significantly lower in treatment group than in control group (P＜ 0.01).Statistical difference was found among three groups at 12,24 and 72 hours (F=371.25,245.61 and 236.22 respectively,P＜0.01). ConclusionsPDGF might have neuroprotective effect,which could inhibit apoptosis of neural cells and decrease the serum NSE concentration.

120 cases were treated by microlaryngoscopic surgery alone from March to December 1985. Among them, 73 cases were polypoid cord, 28 cases vocal cord nodule, and 19 cases of other conditions. The immediate curative results were good in 114 cases, 5 cases fair and only 1 case was poor. The postoperative complications are: dentes primoris moving in 2 cases and aerodermectasia in 1 case. The operation method is very satisfactory through an endotracheal tube without laryngeal injury. It can accomplish the unsuccessful operation done by mirior, direct and fibrous laryngoscopy surgery. The patients were under general anesthesia by an endotracheal tube without any pain or anxiety and can obtain good relaxation. The authors wish to recommend this technique to treat the related laryngeal disease.

BACKGROUND: Nestin is a specific antigen of neural stem cells which widely expressed in lesion of nervous system and brain regeneration.Thus,nestin expression is commonly used to assess whether lesion or damage of the nervous system can promote neural regeneration.OBJECTIVE: To investigate the effects of erythropoietin(EPO)on nestin expression in neural stem cells after hypoxia-ischemia brain damage(HIBD)in neonatal rats from the angles of neural regeneration and activation of neural stem cells.METHODS: HIBD model was established by ligation of the right common carotid artery along with 2-hour 8% hypoxia exposure in neonatal rats.The control group was not subjected to hypoxia-ischemia,and the right common carotid artery was dissociated.The treatment group received an intraperitoneal injection of recombinant human erythropoietin(rh-Epo,5 000 IU/kg)once a day for three days after hypoxia/ischemia,while the two other groups intraperitoneally received normal saline at the same time.In each group,rats were randomly executed immediately,at 4,7,14 days after operation(n = 8).The nestin expression in hippocampal dentate gyrus region was examined by immunohistochemical staining and image quantitative analysis respectively.RESULTS AND CONCLUSION: The number of nestin-positive cells was significantly increased in HIBD group compared to control group at all time points(P < 0.05),and it was also significantly increased in treatment group than the other two groups at all time points(P < 0.05).The numbers of nestin-positive cells in hippocampal dentate gyrus region were significantly increased,and peaked on day 7 after operation in the three groups.The results showed that exogenous rh-Epo could enhance the expression of nestin in hippocampal dentate gyrus region of neonatal rats with HIBD,and promote the proliferation of neural stem cells,rh-Epo plays an important role in the regeneration and repair of neurocytes damaged by hypoxia-ischemia.

AIM:To investigate the effect of Ginkgo biloba extract(EGb761) on cell proliferation and expression of transforming growth factor ?1(TGF-?1) and connective tissue growth factor(CTGF) in rat hepatic stellate cells(HSC-T6).METHODS:HSC-T6 was cultured with EGb761 at concentration of 1,10,100 and 500 mg/L,and without EGb761 as blank control.MTT colorimetric assay was used for detecting the proliferation of HSCs and flow cytometry was used for observing the cell cycles of HSCs under different concentrations of EGb761.The expression of TGF-?1/CTGF mRNA and protein levels were determined by reverse transcription-polymerase chain reaction(RT-PCR) and Western blotting after 24 hours and 48 hours.RESULTS:EGb761 inhibited the proliferation of HSCs at the concentration of 10 mg/L,100 mg/L and 500 mg/L.G0/G1 stage was increased(P

OBJECTIVE:To inves tigate the therapeutic effects of 1,6-fructose diphosphate(FDP) in mice and rat s which were in the induced states of anoxia and acute cerebral ischemia.M ETHODS:Anoxia was induced in mice with a closed normobaric hypoxia chamber .The clinical condition of acute cerebral ischemia was simulated in mice and rat s by decollating and ligating both carotid arteries.FDP was given intragastrical ly in all tests.RESULTS:Intragastric FDP markedly prolonged the surv ival time of mice which were in the induced states of anoxia and acute cerebral ischemia. Intragastric FDP markedly decreased the WBR(wet wt of brain/body wt×1 00) and water weight of brain and inhibited the rise of serum CK in rats with ac ute cerebral ischemia.Intragastric FDP also improved the capacity of blood passi ng through the blood vessel. There was a change in serum LDH,but it was not sign ificant.CONCLUSION:FDP has therapeutic effects in mice and rats to c ounteract the tissue damage caused by the experimentally induced states of anoxi a and cerebral ischemia.

Objective To investigate the value of susceptibility weighted imaging (SWI) in the diagnosis of hemorrhagic diffuse axonal injury (DAI). Methods A retrospective study was conducted on 20 patients with DAI who received MRI examination at day 3 post-injury.MRI sequences included T1WI,T2WI,fluid attenuated inversion recovery ( FLAIR),diffusion weighted imaging (DWI) and SWI.There were 15 patients with the Glasgow Coma Scale (GCS) score≤8,three with GCS score of 9-12 and two with GCS of 13-15.The location and quantity of hemorrhage focus were counted.The area of hemorrhage focus was measured on each MR sequence.Differences of detection rate of hemorrhage focus on each sequence were compared by using X2 test.The correlation between DAI related bleeding area and GCS score was analyzed. Results DAI related hemorrhage focus showed a larger number in superficial cerebrum than that in posterior cranial fossa and in deep cerebrum.The detection rate of hemorrhage focus on SWI was the highest,as compared with other sequences ( P ＜ 0.05 ).Bleeding area and GCS score showed a negative correlation (r =-0.921,P ＜ 0.01 ). Conclusion SWI is very sensitive in detection of the intracerebral hemorrhage focus in the acute period of traumatic DAI.

Objective To evaluate the efficacy of percutaneouse trans-hepatic Cyanoacrylate (TH glue) embolization for gastric varices. Methods TH glue was injected into the gastric varices and its feeder veins in 30 patients. The endoscopy was performed at 1 week and every 3 months after the procedure, while the CT and portal vein angiography were performed at 3 months and every 6 months after the procedure to e-valuate the oblitazation results. Results The effective rate of treatment was 100%. A total of 21 patients were followed up in a mean period of 27.9 months (11-33 months) with a recurrence rate of varices at 14. 29% (3/21). Portal hypertensive gastropathy was observed in 17 patients (80. 95%), and to-bleeding occurred in 2 patients (9. 52%) due to portal hypertensive gastropathy. CT and portal vein angiography dis-played TH glue in fundic peripheral veins, perforating veins in the gastric wall and other feeding veins with-out re-ciroulation or new branches after embolization. Conclusion Peroutaneous trans-hepatic TH glue is a-ble to embolize the gastric varices and its feeding veins, which is feasible and effective in treatment of gastric varices.

Southern rice black-streaked dwarf virus(SRBSDV)is a novel Fijivirus prevalent in rice in southern and central China, and northern Vietnam. Its genome has 10 segments of double-stranded RNA named S1 to S10according to their size. An isolate of SRBSDV, JNi4, was obtained from naturally infected maize plants from Ji'ning, Shandong province, in the 2008 maize season. Segments S7 to S10 of JNi4 share nucleotide identities of 72.6%-73.1%, 72.3%-73%, 73.9%-74.5% and 77.3%-79%, respectively, with corresponding segments of Rice black-streaked dwarf virus isolates, and identities of 99.7%, 99. 1%-99.7%, 98.9%-99.5%, and 98.6%-99.2% with those of SRBSDV isolates HN and GD. JNi4 forms a separate branch with GD and HN in the phylogenetic trees constructed with genomic sequences of S7 to S10. These results confirm the proposed taxonomic status of SRBSDV as a distinct species of the genus Fijivirus and indicate that JNi4 is an isolate of SRBSDV. Shandong is so far the northernmost region where SRBSDV is found in China.

Objective To compare the therapeutic effect of percutaneous transhepatic variceal em-bolization (PTVE) with Cyanoacrylate(TH glue) with that of endoscopic variceal ligatien (EVL) in the treatment of esophageal varlceal bleeding. Methods In this prospective randomized controlled trial, cirrhot-ic patients with acute or recent esophageal variceal bleeding were assigned randomly to PTVE (n = 52) or EVL (n=50) groups. Variants including upper gastrointestinal (UGI) re-bleeding, esophageal variceal re-bleeding, relapse of esophageal variees and survival were evaluated. Results During the follow-up (median 24 and 25 months in the PTVE and EVL groups, respectively), UGI re-bleeding developed in 8 patients (15. 4%) in PTVE group and in 21 (42%) in EVL group (X2 =8. 87, P=0. 005). Recurrent esophageal varices bleeding occurred in 3 patients (5. 8%) in FIVE group and 12 (24%) in EVL group (X2 =5.38, P =0. 012, relative risk 0. 24, 95% confidence interval 0. 05 -0. 74). Reccurent rates of esophageal vari-ces in two groups were 17.3% (9/52) and 52% (26/50), respectively (X2 =13.61, P<0.001). There was no significant difference in survival rate between two groups (X2 = 3.30, P = 0. 054). Conclusion With sufficient embolization of lower esophageal and pefi-esophngeal varices and/or the cardial submucosal and perforating vessels, PTVE was more effective than EVL in the management of esophageal varices recur-rence and re-bleeding.
