OBJECTIVETo observe the effect of Ganoderma lucidum decoction in treating Russula subnigricans poisoning (RSP) patients.

METHODSThe 14 patients of RSP in the treated group were treated with GLD (GLD, one dose was prepared by 100 g of Ganoderma lucidum decocted with water to 600 ml), on the base of conventional treatment, and 11 patients received conventional therapy in the previous year were taken as control. The clinical efficacy and parameters in them were compared, including the urine N-acetyl-D-glucosaminidase (NAG, which reflects the injury of kidney), the red blood cell and protein in urine, the alanine transaminase (ALT, which reflects the injury of liver), and the aspartate aminotransferase (AST, which reflects the injury of heart).

RESULTSA better clinical cure-markedly improving rate was showed in the treated group as compared with the control group, P < 0.01. In the treated group, red blood cell in urine disappeared after 24 hrs treatment in the majority of patients, urinary protein reduced obviously and the other three parameters reached the peak at the 3rd day then lowered gradually. In the control group, all the parameters increased continuously. Comparison between the parameters at corresponding time in the two groups showed significant difference (P < 0.01), those in the treated group were markedly lower than those in the control group respectively.

CONCLUSIONGLD has good effect in treating RSP, could obviously lower the fatat rate of RSP.

Objective To observe the efficacy and safety of applying sirolimus-eluting stents in emergency percutaneous coronary intervention (PCI) for the patients with acute myocardial infarction (AMI).Methods In total,220 patients with AMI were enrolled in this study at Shanghai Tongji Hospital, divided into two groups,one with bare-metal stent and the other with sirolimus-eluting stent.Cardiovascular fatality,major adverse cardiac events (MACE) and target vessel revascularization (TVR) were observed one and six months after PCI in the two groups.Results There was no significant difference in overall fatality and MACE in the 1~(st) or 6~(th) months after PCI between the two groups.Three cardiogenic deaths occurred in bare-metal stent group with a fatality of 2.8 percent,and five deaths in sirolimus-eluting stent group with a fatality of 4.5 percent in six months after PCI.However,rate of restenosis in those with sirolimus-eluting stents was significantly lower than that of bare-metal stents (6.0 percent vs 16.1 percent,P

Abstract: Objective　To investigate the distribution characteristics of HCV genotypes and subtypes in patients with HIV (human immunodeficiency virus, HIV)/HCV co-infection in Kunming based on the nucleocapsid protein gene sequence of HCV (hepatitis C virus). Methods　Serum was collected from HIV/HCV co-infected patients with household registration in 14 county-level cities, districts and counties under the jurisdiction of Kunming, who admitted to Yunnan Provincial Infectious Disease Hospital from March to August 2019. The viral RNA was extracted from the serum, reverse transcribed to synthesize cDNA, and the HCV nucleocapsid protein gene-specific primers were used for nested PCR amplification. The positive amplification products were sequenced, bioinformatics software such as DNAstar and MEGAX were used for sequence analysis. Results　A total of 64 samples from co-infected patients with clinical diagnosis of suspected HIV/HCV were collected and amplified by HCV nucleocapsid protein gene-specific primers, of which 17 samples were amplified positively. The results of sequence analysis showed that the sequences of 9 cases were located in the same evolutionary branch as the HCV 3b subtype sequence, and the nucleotide homology was 93.3%-95.2%; the sequences of 5 cases were located in the same evolutionary branch as the HCV 1b subtype sequence, and the nucleotide homology was 96.8%-97.6%; the sequence of one case and the subtype sequence of HCV 3a gene were located in the same evolutionary branch, and the nucleotide homology was 95.2%; the sequence of one case and HCV 6n gene subtype sequence were located in the same evolutionary branch, and the nucleotide homology was 97.9%; One case was located in the same evolutionary branch as the HCV 6u gene subtype sequence, and the nucleotide homology was 98.4%. Conclusions　HCV 1b, HCV 3a, HCV 3b, HCV 6n and HCV 6u genotypes or subtypes of HCV are prevalent in Kunming, and HCV 3b is the most prevalent genotype.

Objective In this study,we investigated the relationship between oxidative stress,selenoproteins level and onset of Keshan disease (KD) through detecting the expression of 8-hydroxy-2-deoxy guanosine (8-OH-dG),thioredoxin reductase 1 (TrxR1) and glutathione peroxidase 1 (GPx1) in myocardial tissue.Methods Myocardium samples of autopsy patients including 8 cases of KD (KD group included 4 acute KD and 4 chronic KD) and 9 cases of non-KD (control group) were immunohistochemically stained for 8-OH-dG,TrxR1 and GPx1.The staining intensities subsequently quantified by using Olympus Image-Pro Plus 6.0 software.Results The positive rate of 8-OH-dG expression in myocardial nuclei was higher in the case group[(68.6 ± 20.4)％] than that of the control group[(2.4 ± 1.5)％,t =8.515,P ＜ 0.05].In addition,the positive rate of 8-OH-dG expression in acute KD[(91.7 ± 3.7)％] was significantly higher than that of chronic KD[(53.2 ± 7.9)％,t =6.409,P＜0.05].The distribution of TrxR1 and GPx1 was not associated with the distribution of myocardial damage.The expression of these two selenoproteins in KD group (401340 ± 59865,497590 ± 197082) were both lower than that of control group(2790300 ± 379298,1348400 ±615840; t =-28.493,-6.016,respectively,all P＜0.01).Conclusions Oxidative damage is detected in myocardium tissue of KD,and 8-OH-dG expression is associated with the degree of myocardial damage in KD.Selenoproteins,TrxR1 and GPx1,may be closely related to the pathogenesis of KD.

Objective To investigate the prevention and rescuing measures of postoperative fatal bleeding induced by carotid blowout in head and neck tumors. Methods Seven cases with postoperative carotid bleeding treated from October 2003 to August 2009 were reviewed retrospectively. Of the patients, 6 were with common carotid blowout and one with internal carotid artery blowout. All patients underwent preor post-operative radiotherapy for primary head and neck tumours and 3 patients had neck defect repair with deltopectoral skin flap, frontal flap or free radial arm flap respectively. After carotid blowout bleeding, the patients were treated in time with X ray transcatheter intervention including transcatheter arterial embolization (TAE) and self-expanding covered stent implantation, followed by repairing the carotid region with appropriate myocutenous flaps. Results Of 7 patients with carotid blowout, 5 patients were successfully rescured with X ray transcatheter intervention, of them 2 with self-expanding covered stent implantation and 2 with TAE respectively, and other 2 patients died due to rapid bleeding. Of the successfully rescued patients, 2 patients were with the repair of carotid area by pectoralis major myocutaneous flap, one by submental flap and one by local flap, but another one not with flap repair. Follow-up showed the 3 patients rescued with self-expanding covered stent implantation were survival for 6,12,and 20 months, respectively, and the 2 patients rescued with TAE died of repeated carotid blowout in 2 and 13 months later, respectively. Conclusions The planned and timely X ray transcatheter intervention is an effective method to treat carotid blowout bleeding in the patients underwent head and neck tumour surgeries. Compared with TAE, selfexpanding covered stent implantation may be more reliable for restoring the blood supply of head and neck region, with less complications. One-stage repair of caratid region with myocutenous flap is of great importance to protect the carotid and to promote the wound healing.

OBJECTIVETo assess the effects of treatment of Amanita mushroom poisoning with Glossy anoderma Decoction (, GGD).

METHODSTwelve patients with acute Amanita mushroom poisoning received conventional treatment (penicillin and reduced glutathione) combined with oral administration of GGD (treated group), which was prepared out of 200 g Glossy ganoderma decocted in water to 600 mL, and 200 ml was given once, three times a day for 7 successive days; while conventional treatment alone was given to the other 11 patients assigned to the control group. The therapeutic efficacy and changes in serum levels of total bilirubin (TBil), bile acids (BA), alanine transaminase (ALT), and aspartate transaminase (AST) activities in the two groups were compared.

RESULTSThe cured-markedly effective rate in the treated group was more significant than that in the control group (P<0.01). Elevation in TBil, BA, ALT, and AST activities were observed in both groups 3 days after poisoning, which progressively increased thereafter in the control group. In the treated group, they reached their peak on the 3rd day and then declined gradually. The differences between pre-treatment and post-treatment in both groups were obviously significant (P<0.01), so were the differences between the two groups at corresponding time points (P<0.01).

CONCLUSIONGGD shows excellent clinical efficacy in the treatment of acute Amanita mushroom poisoning and can reduce mortality significantly.

In this study, the recombinant adenovirus (Ad) vector containing dual reporter gene [i.e. human transferrin receptor gene (TFRC) and firefly luciferase reporter gene] was constructed to provide a novel experimental tool for magnetic resonance (MR) and bioluminescence dual-modality molecular imaging. The cDNA of TFRC was amplified by polymerase chain reaction (PCR) and cloned into the multiple cloning site of pShuttle-CMV-CMV-Luciferase vector. After identification by Sfi I digestion and sequencing, pShuttle-TFRC-Luciferase vector and the adenoviral backbone vector (pAdeno) were subjected to homologous recombination. The correct recombinant plasmid was then transfected into 293 packaging cells to produce adenoviral particles and confirmed by PCR. After infection of human colorectal cancer LOVO cells with Ad-TFRC-Luciferase, the expressions of transferrin receptor (TfR) and luciferase protein were detected respectively by Western blotting and bioluminescence imaging in vitro. The results showed that TFRC gene was successfully inserted into the adenoviral shuttle vector carrying luciferase gene. DNA sequence analysis indicated that the TFRC gene sequence in the shuttle plasmid was exactly the same as that reported in GenBank. The recombinant plasmid was identified correct by restriction digestion. Ad-TFRC-Luciferase recombinant adenovirus was constructed successfully, and the virus titer was 1.6×10(10) pfu/mL. Forty-eight h after dual reporter gene transfection, the expressions of TfR and luciferase protein were increased significantly (P<0.01). It was concluded that the recombinant adenovirus vector with dual reporter gene was successfully established, which may be used for in vivo tracing target cells in multimodality imaging.

OBJECTIVE: To explore the effect of thrombin precondition (TPC) on the rat cerebral astrocytes(As) cultured in oxygen-glucose deprivation (OGD). METHODS: Astrocytes were pretreated with thrombin (TB) at various concentrations (0.005 approximately 5.000 kU/L), and then insulted by OGD. The cell damage and viability were evaluated by the lactate dehydrogenase (LDH) effusion rate and the 3-(4,5-dimethylthazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) conversion method. Detection of apoptotic cells was determined by the flow cytometry technique. The glutamate uptake of astrocytes was studied with [3H]-glutamate incorporation. RESULTS: OGD increased the LDH, decreased the cell viability, increased the number of apoptotic astrocytes, and decreased the glutamate uptake (P<0.01). While preconditioned with thrombin at the same condition, the LDH decreased, the cell viability increased, the percentage of apoptotic cells decreased, and the glutamate uptake increased (P<0.05). The maximum protective effect of thrombin was observed at 0.1 kU/L. CONCLUSION Low concentration of thrombin precondition (TPC) can protect the astrocytes from oxygen-glucose deprived injury, and attenuate its apoptosis in a dose-dependent manner.
