Objective To explore a reasonable therapeutic plan for treating HIV/AIDS with traditional Chinese medicine plus western medicine. Methods Twenty-nine patients with HIV/AIDS were selected and recruited into a HIV group and a AIDS group according to the clinical diagnosis. Each group was further divided into comparison stage and treatment stage. In HIV group, observations and statistics of observation indexes were performed during the comparison stage; while TCM treatment was applied in the treatment stage. In AIDS group, HAART was applied in the comparison stage, and HAART combined with TCM therapy were used in the treatment stage. Both comparison stage and the treatment stage lasted 12 months. Results In HIV group, self control results showed that immune and virus indexes did not have significant changes, but also with no side or toxic effects, In the AIDS group, contrasting between the comparison stage and the treatment stage showed that there were significant improvement of symptoms (χ2=4.9231, 2.5000, P<0.05) , anti-toxic effects (χ2=9.333、 16.4091、10.2273, P<0.01) and immune indexed(t=3.1990,P<0.01) after treated additionally with traditional Chinese medicine. Conclusion Traditional Chinese medicine could improve the immunity function and clinical symptoms, reduce side effect of HAART medicine and stabilize CD4+ T cells of patient with HIV/AIDS.

Objective To evaluate the efficacy and safety of the interventional techniques for emergent treatment of iatrogenic renal injuries.Methods Nine patients with iatrogenic renal vascular injuries were treated with superselective renal arterial embolization.The causes of renal injury included post-renal biopsy in 5 patients,endovascular interventional procedure-related in 2,post-renal surgery in 1,and post-percutaneous nephrostomy in 1 patient.The patients presented clinically with hemodynamical unstability with blood loss shock in 7 patienrs,severe flank pain in 7,and hematuria in 8 patients.Perirenal hematoma was confirmed in 8 patients by CT and ultrasonography.The embolization materials used were microcoils in 7 and standard stainless steel coils in 2 patients,associated with polyvinyl alcohol particles(PVA)in 5,and gelfoam panicles in 2 cases.Results Renal angiogram revealed intra-renal arteriovenous fistula in 6 cases,intrarenal pseudoaneurysm in 2 cases,and the contrast media extravasation in 1 patient.The technical success of the arterial embolization was achieved in all 9 cases within a single session.All angiographies documented complete obliteration of the abnormal vessels together with all major intrarenal arterial branches maintaining patent.Seven patients with hemodynamically compromise experienced immediate relief of their blood loss related symptoms,and another 7 with severe flank pain got relief progressively.Hematuria ceased in 8 patients within 2-14 days after the embolization and impairment of renal function occurred after the procedure in 5 cases,including transient aggrevation(n=3)and developed new renal dysfunction(n=2).Two of these patients required hemodialysis.Perirenal hematoma were gradually absorbed on ultrasonography during 2-4 months after the procedures.Follow-up time ranged from 6-78 months(mean,38 months),4 patients died of other primary diseases of renal and multi-organ failures.Five patients are still alive without further intervention,and suffering no more of rebleeding and deterioration of renal function.Conclusions Transcatheter selective renal arterial embolization is safe and effective in the treatment of iatrogenic renal vascular injuries,resulting in permanent cessation of bleeding.(J Intervent Radiol,2007,16:807-810)

Objective To describe the manifestations of the inferior phrenic arteries(IPA)supply to the pulmonary hemorrhagic lesions and to evaluate the safety and efficacy of transcatheter arterial embolization(TAE)of the IPA.Methods The clinical data and imaging findings of eighteen patients with the additional blood supply to the pulmonary hemorrhagic lesions from the IPA were evaluated retrospectively.The causes of the bleeding were lung malignancies in 9,bronchiectasis in 7,and chronic inflammation in 2 patients.TAE supplementally was performed in patients with IPA supply to the pulmonary lesions,using polyvinyl alcohol particles,gelatin sponge particles,and microcoils.Results Selective arteriogram demonstrates an enlarged IPA,with numerous branches and hypervascularity in all 18 cases, with tumor staining in 9,the contrast material extravasation in 6,and non-specific staining in 2 cases.In addition,IPA-to-pulmonary shunting was found in 9 cases.All the lesions supplying by IPA were adjacent to the pleurae,including adjacent to the diaphragmatic pleura in 11,the mediastinal pleura in 5,and the lateral pleura of the lower lobe in 2 cases.Technical success of IPA embolization was achieved in the 18 cases.Embolization of other nonbronchial systemic arteries(the internal thoracic artery in 7 and intercostal artery in 3)was performed at the same session.All bleeding ceased immediately after supplemental IPA embolization.Follow-up time ranged from 8 months to 4 years.Mild recurrent hemoptysis occurred in 3 patients at 1,2,6 months respectively,after the embolization.These patients were responsive to conservative management.Recurrent bleeding did not occur in 15 patients during the follow-up. Conclusion The pulmonary hemorrhagic lesions,especially adjacent to the diaphragmatic and mediastinal pleurae,can be supplied by IPA,and may result in clinical failure following BAE.Supplemental TAE of IPA is a safe and effective adjunct to BAE in the management of bronchial bleeding supplied by IPA.

Objective Increasing evidence suggest that aberrant activation of PI3K/Akt is involved in many human cancers, and that inhibition of the PI3K/Akt pathway might be a promising strategy for cancer therapy. The study is to evaluate the effects of combined therapy of PI3K inhibitor (LY294002) and Ad-PTEN in athymic mice xenogeneic transplant model of human glioma and to reveal the possible mechanisms involved.Methods Twenty-four athymic mice were randomly divided into 4 groups (DMSO、Ad-vector plus DMSO、LY294002 alone and Ad-PTEN plus LY294002), and were treated, respectively. Athymic mice xenogeneic transplant model was established by inoculation (sc) with LN229 glioma cells. Body mass (BM) and diameter of tumor mass were measured. Furthermore, The protein expressions of PTEN、p-Akt、CyclinD1、Caspase-3、MMP-2、p-FAK in tumor tissues were analyzed with immunohistochemistry.Results The tumor-inhibiting rate of was significantly higher in Ad-PTEN plus LY294002 than in the LY294002 alone (92.46 vs 65.59%)( P <0.05).The protein expressions of PTEN and Caspase-3 were significantly higher, while PCNA、CyclinD1、bcl-2 and MMP-2、p-FAK was significantly lower in Ad-PTEN plus LY294002 group than in the other three groups ( P <0.05).Conclusions LY294002 plus Ad-PTEN achieve better outcome than either alone in treating glioma possibly through enhancement of the inhibitory action of PI3K/Akt pathway and Ad-PTEN pathway.

OBJECTIVE To investigate the develop mental toxicity of muscone to embryos. METHODS With zebrafish embryos as a model,The 3 h post fertilization (hpf)embryos were exposed to muscone at 5,10,20,40,80 and 160 μmol·L -1 culture solutions for 96 h and inspected daily with mi-croscopy for larval morphology.The drug solution was replaced every 24 h.Spontaneous move ments were checked at 24 hpf.Heart rate at 48 hpf,hatching rate,e mbryo deformity rate and mortality rate were evaluated.The expression of sepn1 was determined with real-ti me quantitative PCR technique at 96 hpf.RESULTS The 24 hpf spontaneous move ments showed no significant difference.At 48 hpf, spine curvature,pericardial ede ma,yolk sac ede ma,and abnormal swi mming were observed.In addition, the 48 hpf heart beats(10 s)was decreased fro m 26.5 ±1 .0 to 18.0 ±1 .9(P <0.01 ).At 48 hpf , hatching rate of 5 ~40 μmol·L -1 decreased(P <0.05),while of 160 μmol·L -1 increased (P <0.05) co mpared with muscone 0 μmol·L -1 .Muscone had little effect on hatching rate at other ti me points;Mal-formation rate and mortality rate at higher concentrations were up to 100%.The sepn1 gene expression at 96 hpf in the exposure groups decreased co mpared with that of control group(P <0.01 ).CONCLU-SION Muscone had toxic effects on the develop ment of zebrafish embryos,including spine curvature, abnormal swi mming,and pericardial ede ma.These effects may be related to the inhibition of sepn1 gene expression by muscone.

Objective To investigate the therapeutic effect and safety of microneurosurgery associated with Gamma Knife radiosurgery on the large meningiomas in sellar region, and to clarify its clinical curative effect. Methods The clinical data of 34 patients with large meningiomas in sellar region underwent microsurgery were retrospectively analyzed.All of them underwent microsurgery,and then treated with Gamma Knife radiosurgery in one month after operation if there were residual tumors.The tumor removal of situation,complication,rate of symptom remission,and recurrence rate were analyzed.Results Among the 34 patients,total resection (7 cases of Simpson grade Ⅰ and 12 cases of Simpson grade Ⅱ)was achieved in 19 cases (55.9%),subtotal resection (Simpson grade Ⅲ )in 14 cases (41.2%), and partial resection (Simpson grade Ⅳ )was achieved in 1 case (2.9%).The major complications were cranial nerve injuries (such as oculomotor nerve, trochlear nerve and abducens nerve,n=6),the contralateral limb paresis (n = 2),postoperative bleeding (n = 1),CSF leak with infection (n=3),and secondary epilepsy (n = 3 ); no death occurred postoperatively. All these patients were followed up for about 3 to 48 months.Postoperative headache disappeared in 24 cases (80%),and 6 cases were alleviated (20%);postoperative vision improved in 12 cases (80%),remained unchanged in 2 cases (13.3%)and deteriorated in 1 case (6.7%); postoperative olfactory function improved in 5 cases (62.5%) and 3 cases unchanged (37.5%); 5 cases recoverd from the ocular motility disorder (71.4%), and 2 cases unchanged (28.6%);7 cases recoverd from thehemiplegia (100%).One of the total resection cases (5.2%)and two of the non-total resection (13.3%)suffered from tumor recurrence.All of the non-total resection cases were treated with Gamma Knife radiosurgery.Conclusion The clinical effect of microneurosurgery associated with Gamma Knife radiosurgery in treatment of large meningiomas in sellar region is satisfactory.

Objective To measure and define the distribution of left gastric lymph nodes.Meth- ods From Jan.2004 to Apr.2005,silver clips were set around the root of the left gastric artery in 124 pa- tients with esophageal and gastric cardia carcinoma,X-ray films at 0?and 90?simulator gantry in the radio- therapeutic position were taken.Then,the data of the superior,lower,left,right,anterior and posterior bor- der in each patient was recorded.With SAS 8.02 software,data of minimum area which covered the left gas- tric lymph node in different incidences were obtained.Results According to the analysis of Shapiro- Wilk,Kolmogorov-Smimov,Cramer-von Mises and Anderson-Darling tests,each border was of normal distri- bution,with equal frequency in the male and female,despite the actual results in different genders.Pearson Correlation Coefficients analysis did not suggest a significant relationship between the border and height, weight and size of vertebrae,which formed the minimum area covering the left gastric area at frequency of 100%,95%,90% and 85%,which were drawn out through the calculation.Conclusions Aiming at completely identifying the normal distribution of the left gastric lymph node,more patients are required to be in the pool.For the time being,location in the left gastric area can be obtained from details of the results in the present study.

Objective This study was designed to examine the clinical characteristics of bloodstream infections (BSI) caused by Staphylococcus aureus in a teaching hospital and the risk factors for 30-day mortality.Methods A single center retrospective cohort study was conducted for all the patients with BSI caused by S.aureus between 2008 and 2015.The data of clinical features,microbiology,and 30-day mortality were collected from the database of electronic medical records.Results A total of 121 patients with S.aureus BSI were identified.The prevalence of methicillin-resistant S.aureus (MRSA) was 17.4％ (21/121).MRSA BSIs were significantly associated with old age (≥65 years) (P=0.026),hospital acquired infection (P=0.035),respiratory tract infection (P=0.001),polyinfection (P=0.005) and inappropriate initial antibiotic therapy (P=0.001) than methicillin-sensitive S.aureus (MS SA) BSIs.The 30-day mortality was 18.2％ (22/121).Both univariate and multivariate analysis suggested that solid tumor (OR,8.932,P=0.004) and septic shock (OR,56.721,P＜0.001) were independently associated with the 30-day mortality.Conclusions The present study confirms that solid tumor and septic shock are more important risk factors than MRSA in mortality of patients with S.aureus BSI.
