Objective To observe clinical application value of percutaneous interventional techniques for the treatment of complications of AIDS.Methods Twenty-one AIDS patients with complications were enrolled.CT guided percutaneous needle biopsy and drainage were conducted,and the correct rate of diagnosis,clinical curative effect and complications post-interventional therapy were observed.Results The operations of all patients executed successfully.Fourteen patients underwent 16 times biopsy,11 were correctly diagnosed,the diagnostic accordance rate was 81.25%.Drainage was performed in 6 patients with abscess or cystis,then the lesions completely disappeared in 3,deflated in 2,while the rest one needed continously draining.Partial splenic embolization (50%) was performed in 1 patient,and after operation platelet content increased,while hepatic function decreased temporality.No complicated infection and other severe complications occurred.Conclusion Percutaneous interventional techniques for the treatment of complications of AIDS are safe and feasible.Medical staffs should be careful to exposition of HIV infection.

A series of [1,3]dioxolo[4,5-f]isoindolone derivatives were designed, synthesized and evaluated as inhibitors of acetylcholinesterases (AChE). Furthermore, their effects on memory impairment of mice induced by scopolamine were investigated with step-through test. The results suggested that most of the target compounds exhibited potential inhibition on AChE with IC50 values at micromolar range. Compounds I1 (IC50 value of 0.086 μmol · L(-1)) and I2 (IC50 value of 0.080 μmol · L(-1)) showed the strongest AChE inhibitory activity, which are equipotent to donepezil (IC50 value of 0.094 μmol · L(-1)). Moreover, compounds I1-I4 could improve the memory impairment induced by scopolamine in mice.

A series of novel 4-substituted-3-nitrobenzamide derivatives were designed and synthesized. The structures of the target compounds were confirmed with 1H NMR, 13C NMR, MS and element analysis. Anti-tumor activities against HCT-116, MDA-MB435 and HL-60 cell lines in vitro were evaluated by SRB assay. The results indicated most of the target compounds exhibited potent anti-tumor activity. Compound 4a showed the most potent inhibitory activities against three cancer cell lines with the GI50 values of 1.904-2.111 micromol x L(-1). Compounds 4g, 41-4n exhibited more potent inhibitory activities against MDA-MB435 and HL-60 cell lines with the GI50 values of 1.008-3.586 micromol x L(-1) and 1.993-3.778 micromol x L(-1), respectively. The structure-activity relationship of these compounds is discussed preliminarily.

Taking Matou goat ear margin as the study material, we succeeded in established a fibroblast cell line by the method of explant culture directly. Observations on morphology, dynamic growth, determination of viability, analysis of karyotype, test of microorganism and other characteristics were detected. Results showed: Population Doubling Time (PDT) of cells was approximately 36 h; Cell viability was 96.7% after thawing; The status of cell After passage was constant; Analysis of chromosomal karyotyps indicated that diploid (2n=60) account for 98% in the cell line. Every index in the cell line met all the standard quality controls of ATCC in USA. The established of Matou goat ear fibroblast cell line has not only important genetic resources preserved at the cell level, but also valuable material for genome, postgenome and somatic cell nuclear transfer research.

Objective: To study the clinical characteristics, methods of diagnosis and treatment of hyperornithinemia-hyperammonemia- homocitrullinuria (HHH) syndrome. Method: From July 2011 to August 2016, 3 Chinese patients with HHH syndrome were enrolled in this study. The clinical course, biochemical features, brain MRI findings, and gene mutations were analyzed. Result: The three patients′ age at onset of symptoms was 3 months to 7 years, and the age of diagonosis was 3 years and 10 months to 9 years and 10 months. All of them presented with intolerance to protein-rich foods from the infant period, development retardation and abnormal posture. Case 1 and 2 had moderate mental retardation. Serum ammonia 25-276 μmol/L (reference range<60 μmol/L), alanine aminotransferase (ALT) 20-139 IU/L (reference range 9-50 IU/L), ornithine 29.12-99.44 μmol/L(reference range 15-100 μmol/L), urinary orotic acid 1.49-29.75 mmol/mol Cr (reference range 0-7 mmol/mol Cr), uracil 6.09-103.97 mmol/mol Cr (reference range 0-1.5 mmol/mol Cr). The cranial MRI revealed lesions in the basal ganglia, abnormal white matter signal, progressive demyelination and cerebral atrophy. On their SLC25A15 gene, a novel homozygous missense mutation c. 416A>G (p.E139G) was identified in case 1, a known pathogenic homozygous nonsense mutation c. 535C>T was found in case 2 and 3. Liver transplantation had been performed when case 1 was 6 years old. Significant improvements were observed in dietary habit, mental and motor functions, and biochemical parameters. After the dietary intervention with the supplements of arginine, L-carnitine, case 2 was improved, spastic paraplegia of case 3 had no mitigation. Liver transplant was recommended. Conclusion HHH syndrome has an aversion to protein-rich food, and the patients have recurrent vomiting and progressive neurological dysfunction. Clinical diagnosis of HHH syndrome is difficult and patients may present with incomplete biochemical phenotype. The genetic analysis is key for the diagnosis. Depending on their condition, individuals with HHH syndrome can be treated with a low-protein diet, drugs and liver transplantation.

OBJECTIVE：To study the effects and mechanism of oncolytic virus M 1（called M 1 virus for short ）inducing the apoptosis of cervical cancer C-33A cells. METHODS ：MTT assay was used to detect survival rate of C- 33A cells that were treated with different titers （0，0.001，0.01，0.1，1，10 PFU/cell）of M 1 virus. C- 33A cells were divided into control group （0 PFU/cell）， low-dose，medium-dose and high-dose groups of M 1 virus（0.001，0.01，0.1 PFU/cell）. After treated with corresponding titers of M1 virus for 48 h，flow cytometry was used to detect the apoptotic rate and infection rate of cells；Western blot was performed to detect the protein expression of C/EBP homologous proteins （CHOP），caspase-12，caspase-3 and cleaved-caspase- 3. RESULTS ： After treated with different titers of M 1 virus，the survival rate of C- 33A cells decreased significantly （P＜0.01），and showed a dose-dependent tr end. Compared with control group ，the apoptotic rate and infection rate of cells in M 1 virus groups as well as the protein expression of CHOP ，caspase-12 and cleaved-caspase- 3（except for medium-dose group ）in M 1 virus medium-dose and high-dose groups were increased significantly （P＜0.01）. CONCLUSIONS ：M1 virus can induce the apoptosis of cervical cancer C-33A cells ，and its mechanism may be related to the activation of endoplasmic reticulum stress pathway.
