OBJECTIVETo investigate the effect of Shenqi Fuzheng Injection (SFI) for hemopoietic and immune function reconstruction in patients with hematologic malignancies (HM) after chemotherapy.

METHODSEighty HM patients at remission inducing stage of initial treatment were randomly assigned to two groups, the treatment group treated with SFI (250 mL daily) plus chemotherapy and the control group only treated with chemotherapy for 14 days, with same supportive treatments administered to both. Levels of blood routine test, T lymphocyte subsets (CD3+, CD4+, CD4+ /CD8+) and B lymphocyte subsets CD3- CD19+ were determined before and after treatment, and the remission rate was assessed after treatment.

RESULTSThe remission rates in the two groups showed no significant difference [90% (36/40) vs 82.5% (33/40), P > 0.05] statistically. Levels of peripheral leucocyte count and hemoglobin as well as levels of CD3+, CD4+, CD4+ /CD8+; were significantly higher in the treatment group than in the control group (P < 0.05), but no significant difference was shown between groups in CD3- CD19+ level.

CONCLUSIONSFI can lighten the inhibition of chemotherapy on hemopoietic function of bone marrow, and promote its recovery, enhance the immune function, and improve the quality of life in patients with HM undergoing chemotherapy.

Objective To summarize and analyze clinical diagnosis and surgical treatment methods of 11 cases with congenital coronary arterial fistula (CCAF). Methods The clinical data of 11 patients who were definited by ultrasonic cardiogram, CT angiography (CTA) and coronary angiography were analyzed retrospectively. Four cases were simple CCAF, 7 cases coexisted with other heart abnormalities. Six cases were given surgical closure of fistula without cardiopulmonary bypass. One of the cases adopted coronary artery under the tangent cotton-padded mattress suture, and 4 cases fistula arterial were ligatured directly. Six cases were given surgical closure of fistula under cardiopulmonary bypass. The right coronary arterial was opened in three of the cases with right coronary artery aneurysm to close fistula. The chambers of heart in the others were opened to close fistula. Results All patients received surgical treatment successfully, and no death happened during the operation. The ultrasonic cardiography showed that all patients recovered well. Follow-up was conducted on 10 patients with the time period ranging from 3 months to 5 years. There was no death and no complication. Conclusions Combined application of ultrasonic cardiogram, coronary angiography and CTA increases the accuracy rate of diagnosis greatly and offers visual bases to formulate operation plan. Surgical operation is quite effective for congenital coronary arterial fistula after definite diagnosis. Operator should try to reserve the expanded coronary arterial, strengthen the anticoagulant after opeation to prevent thrombosis.

Objective To study the relationship between the genetic polymorphisms of carboxylesterase 1 gene (CESI) and the susceptibility to antituberculosis drug-induced hepatotoxicity (ATBDIH).Methods Genetic polymorphisms of CES1 in 473 tuberculosis patients with or without hepatotoxicity (200∶ 273) after antituberculosis chemotherapy were analyzed by PCR-MassArray.Results In4 tags of CES1 single nucleotide polymorphism (SNP),the frequency of the rs1968753 allele had statistical difference between the hepatotoxicity group and the no-hepatotoxicity group ( P =0.0236 ).The characteristics of anti-hepatotoxicity had been shown relationship with rs8192950 ( P =0.044,OR =0.649,95％ CI =0.426-0.989,AC/AA ) and rs1968753 ( P =0.048,OR =0.556,95％ CI =0.311-0.995,GG/AA).The diplotypes with ‘ CGC' haplotype exhibited significant protection against hepatotoxicity at one copy (P=0.048,OR=0.654,95％CI=0.430-0.996).Conclusions The genetic polymorphisms of CESI might have significant association with ATBDIH.SNP rs8192950 AC genotype and rs1968753 GG genotype might be the candidates for risk prediction of ATBDIH.

OBJECTIVE: To summarize the clinical experience of endoscopic repair for cerebrospinal fluid (CSF) rhinorrhea in our department in the last 4 years. METHOD: Clinical data of 16 patients with CSF rhinorrhea who underwent nasal endoscopic repair was analyzed retrospectively. The effect of etiology, image data, location of CSF leaks and surgical techniques on treatment were discussed. RESULT: Among the 16 patients, 10 were diagnosed with spontaneous CSF rhinorrhea, 2 were diagnosed with traumatic CSF rhinorrhea, 3 were diagnosed with CSF rhinorrhea after catching cold and 1 was diagnosed with meningo-encephalocele in with CSF rhinorrhea. The leak was located by CT scan in 11 cases, by MRI in 7 cases. The common locations of the defect were the frontal sinus (3 cases), cribriform roof (3 cases), sphenoid sinus (6 cases) and the nasal cavity top (4 cases). All the cases were successfully cured after the first nasal endoscopic repair with autologous materials. None of patients had a reoccurrence during 10 to 42 months follow-up time. CONCLUSION The application of CT and MRC before surgery which could make an accurate diagnosis of the location and the size of the defect. The correct selection of repair materials, processing planting bed around the leakage and complete contacting leakage with graft bed are the key points to the successful surgery of CSF rhinorrhea.

A rare strain of actinomycetes, with broad-spectrum antimicrobial activity, was isolated from the soil samples from the farmland in the area of Yaohu lake in Nanchang. The information about the taxonomic identification, such as the morphology, physiological properties, cell components and 16S rRNA gene se-quences, suggested that the rare strain of actinomycetes was identified as Micromonospora carbonacea.

Based on the strain of Micromonospora carbonacea JXNU-1 with board-spectrum antimicrobial activity, the technology for the isolation and purification of antibiotic from the fermentation broth of the Micromonospora carbonacea, and its physical-chemical properties were studied. The results showed that, the antibiotic was stable under the condition of high temperature and alkali, but not in acid solution. After the pretreatment of centrifugation and filtration to remove the cells and lipids, the antibiotic was absorbed to negative exchange resin, and the impurity was excluded when 2 mol/L NaCl was used as primary eluent. The antibiotic could be eluted with 20% alcohol as eluent, and the eluting speed of the antibiotic was greatly accelerated as 2 mol/L NaCl was added into 20% alcohol as final eluent. Aqueous solution of the antibiotic was yielded from the alcohol-salt eluant by decompression concentration to wipe off alcohol and by dialysis to exclude salt. One active component was detected in antibiotic solution by paper chromatography, and theHPLC purity was over 99%. As the antibiotic shows positive color-forming reaction to Molish reagents, Benedict’s reagents and Diohenvlamine reagents, combined with the characteristics of absorption spectra, it is deduced that the antibiotic belongs to nucleoside antibiotics.

In order to reveal genetic diversity of domestic Andrographis paniculata and its impact on quality, genetic backgrounds of 103 samples from 7 provinces in China were analyzed using SRAP marker and SNP marker. Genetic structures of the A. paniculata populations were estimated with Powermarker V 3.25 and Mega 6.0 software, and polymorphic SNPs were identified with CodonCode Aligner software. The results showed that the genetic distances of domestic A. paniculata germplasm ranged from 0. 01 to 0.09, and no polymorphic SNPs were discovered in coding sequence fragments of ent-copalyl diphosphate synthase. A. paniculata germplasm from various regions in China had poor genetic diversity. This phenomenon was closely related to strict self-fertilization and earlier introduction from the same origin. Therefore, genetic background had little impact on variable qualities of A. paniculata in domestic market. Mutation breeding, polyploid breeding and molecular breeding were proposed as promising strategies in germplasm innovation.

OBJECTIVETo explore the antitumoral effect of indirubin on androgen-independent prostate cancer PC-3 cells and its possible mechanisms.

METHODSWe measured the inhibitory effect of indirubin on the proliferation of prostate cancer PC-3 cells using MTT assay, detected their cell cycles by flow cytometry, and determined the expressions of the cell cycle regulatory protein cyclin D1 and its related downstream gene c-myc by Western blot.

RESULTSThe viability of the PC-3 cells was significantly decreased by indirubin in a concentration-dependent manner, reduced to 52. 2% and 13. 6% at 5 and 10 µmol/L, respectively. The cell cycle of the PC-3 cells was markedly inhibited by indirubin at 5 µmol/L, with the cells remarkably increased in the G0 and G1 phases and decreased in the S and G2/M phases. Meanwhile, indirubin also inhibited the expressions of cyclin D1 and c-myc in the Wnt signaling pathway.

CONCLUSIONIndirubin can suppress the proliferation of androgen-independent prostate cancer PC-3 cells, which may be associated with its inhibitory effect on the cell cycle and Wnt signaling pathway.

OBJECTIVETo investigate the effects of peroral endoscopic myotomy(POEM) on esophageal dynamics in patients with esophageal achalasia.

METHODSFrom September 2011 to November 2011, 20 cases with esophageal achalasia received POEM at the Endoscopic Center in the Zhongshan Hospital of Fudan University. Pre-operation esophageal dynamics of all the patients were evaluated by high resolution manometry(HRM) system and 3 days after operation the test was repeated. Lower esophagus sphincter resting pressure(LESP), 4-second integrated relaxation pressure(4sIRP), lower esophagus sphincter relax rate(LESRR), lower esophagus sphincter length(LESL), and esophageal manometry were analyzed.

RESULTSAfter POEM, LESP decreased from(29.1±17.0) mm Hg to(14.6±4.9) mm Hg, and decrease rate was 49.8%(P<0.01). However, the decreases in LESRR and LESL were not statistically significant(P>0.05). Esophageal peristaltic contraction was absent in all the 20 patients preoperatively. After POEM, changes in the esophageal contraction were seen in 7 patients, and peristalsis was noticed but was below normal level. There were no significant changes in peristalsis in the remaining 13 patients.

CONCLUSIONPOEM can significantly reduce LESP and 4sIRP in patients with achalasia, but can not affect the contraction of the esophagus.
