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

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.

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 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 study the effect of anti-CD25 monoclonal antibody (mAb) combined with antithymocytic globulin (ATG) in the treatment of severe steroid-resistant acute graft-versus-host disease (aGVHD) after unrelated donor hematopoietic stem cell transplantation (UD-HSCT).

METHODSTen leukemic patients who developed severe steroid-resistant aGVHD during UD-HSCT received a standard dose of anti-CD25 mAb and a medium or low dose of ATG. The effect on aGVHD control, patients' survival, infection and relapse after the therapy were analyzed.

RESULTSEight of the 10 patients had complete remission and 2 had partial remission after the combined therapy. In the 8 patients with complete remission, 2 developed third degree aGVHD 3-3.5 months after the transplantation, and were managed with a second combined therapy to successfully achieve complete remission. In the total of 12 combined treatments, the median time of therapeutic effect was 5 days (3-10 days); the median complete relief time was 12 days (8-30 days) in the 10 cases. Among the 8 patients who survived for more than 3 months, 7 were diagnosed to have chronic GVHD including 4 with extensive chronic GVHD. No relapse of leukemia was found in these patients. Five patients survived the 2-year-long follow-up after the transplantation with survival time over 2 years; of the 5 patients who died within 2 years after the transplantation, 1 survived for more than one year, and 4 for less than 6 months. Two patients died from invasive fungal infection, two from aGVHD and one from cGVHD-induced multiple organ failure.

CONCLUSIONAnti-CD25 mAb combined with ATG has good therapeutic effect on steroid-resistant sever aGVHD and may help achieve high complete remission rate and long-term survival in leukemic patients after UD-HSCT.

OBJECTIVETo evaluate the role of human leukocyte antigen G (HLA-G) in the better effect of allogenetic bone marrow transplantation than that of peripheral blood stem cell transplantation.

METHODSFlow cytometry was used to detect the expression of membrane-bound HLA-G (mHLA-G) on donor peripheral blood (PBC) or bone marrow (BM) mononuclear cells. The levels of soluble HLA-G (sHLA-G) in the plasma and bone marrow fluid were determined using enzyme-linked immunosorbent assay (ELISA) before and after granulocyte colony-stimulating factor (G-CSF) mobilization.

RESULTSThe mean levels of mHLA-G after G-CSF mobilization in the PBC and BM were significantly higher than that before G-CSF mobilization (P=0.001 and 0.000), but the plasma levels of sHLA-G showed no significant changes after the mobilization (P=0.279). The mean levels of sHLA-G in the BM fluid significantly increased (P=0.002) to a level higher than that in the PBC after G-CSF mobilization (P=0.004).

CONCLUSIONHLA-G plays an important role in immune tolerance after hematopoietic stem cell transplantation with G-CSF mobilization.
