Objective: To explore the intervention effect of Yishenbaozhen Recipe (YSBZR) on the renal anemia in rats with chronic renal failure and the related mechanism. Methods: Totally 43 rat models of chronic renal failure were produced by two-step 5/6 nephrectomy. The study was randomly divided into 5 groups: normal control group (n=9), model group (n=8), YSBZR high-dose group (n=9, 46. 5 g/[kg • d]), YSBZR low-dose group (n=9, 15. 6 g/[kg • d]) and Niaoduqing group (n=8, 2.5 g/[kg • d]). YSBZR was given intragastrically on a daily bases for 6 weeks, and then the serum erythropoietin (EPO), serum creatinine (SCr), blood urea nitrogen (BUN), hemoglobin (Hb), red blood cell count (RBC), and mean corpuscular volume (MCV) were examined. Results: Compared with the model group and Niaoduqing group, YSBZR high-dose group and low-dose group had significantly higher Hb, RBC and EPO levels (P<0.05), and had similar MCV levels. YSBZR high-dose and low-dose groups had significantly decreased SCr and BUN levels compared with the modll group (P<0.01), and had similar levels when compared with Niaoduqing group. Conclusion: YSBZR has interventional effect on renal anemia, which might be related to decreasing nitrogen retention, reducing the toxin-induced inhibition of hematopoietic system, and increasing EPO level.

Objective: In this work, phylogenetic analysis was used to compare the ITS2 and psbA-trnH sequences of Polygonatum cyrtonema samples from different geographical sources, so as to explore the genetic diversity and genetic relationship of these resources. Methods: PCR method was used to amplify the regions of ITS and psbA-trnH, and the sequences of ITS2 and psbA-trnH were obtained after the amplified fragment sequences were blasted in NCBI database. The neighbor joining (NJ) and maximum parsimony (MP) methods were used to construct phylogenetic trees and Kimura two-parameter (K2-P) model was used to calculate the genetic distance of different samples. Mega and DNAman softwares were applied for mutiple alignment of ITS2 and psbA-trnH sequences of 25 samples of P. cyrtonema. Results: The lengths of ITS2 and psbA-trnH sequences of Anhui Qingyang and Fujian Taining samples of P. cyrtonema were 224 bp and 620 bp, respectively. The lengths of ITS2 and psbA-trnH of the remaining 24 samples were 225 bp and 621 bp, respectively. ITS2 and psbA-trnH had seven and four mutation points, respectively. These 25 samples were clustered into two groups based on ITS2 sequences. Five samples in Hunan and Guizhou were clustered into one group, while the other 20 samples were clustered into another group. The genetic distance showed that the samples from Huaxi and Jianhe in Guizhou Province and Jianyang in Fujian Province had the largest genetic distance. Phylogenetic tree constructed by psbA-trnH sequences were unable to distinguish 25 samples from different geographical sources. Conclusion: Phylogenetic and mutation analysis will provide the theoretic foundation to utilize the resources of P. cyrtonema, investigate their evolution, and evaluate their genuineness. The results of mutation point will also be used in the identification of related P. cyrtonema resources.

Objective To analyze the bacterial diversity in stem rot and healthy plants of Paris polyphylla var. chinensis. Methods Bacterial strains were isolated from rhizomes, stems and leaves of the diseased and healthy plants of P. polyphylla var. chinensis using beef extract-peptone medium. Using 16 S rRNA universal primers 27F/1492R for PCR amplification, combined with DNA sequencing technology to preliminary identification the bacterial strains. Results The bacteria could be divided into 23 microbial species, belonging to 11 genera, isolated from healthy and diseased plants of P. polyphylla var. chinensis. Eleven endophytic bacteria, belonging to 4 genera were contained from healthy plants, in which there were 9, 10, and 5 species isolated from rhizomes, stems and leaves, respectively. Fourteen endophytic bacteria, belonging to 10 genera were contained from diseased plant, in which there were 11, 8, and 3 species isolated from rhizomes, stems, and leaves, respectively. The content of endophytic bacteria in rhizome of healthy plant was the highest, reached up to 2.999 × 105 cfu/g, while that in leaf was the lowest with 7.32 × 104 cfu/g. The quantities of Bacillus species in rhizome (73.3%), stem (67.1%), and leaf (81.8%) of healthy plant were the highest groups, Pseudomonas species in rhizome (35.6%), stem (50.3%) and leaf (60.5%) of diseased plants were the highest groups. Shannon-Wiener index and evenness index of healthy plant of P. polyphylla var. chinensis were higher than that of diseased plants. Conclusion The dominant group in the healthy plant of P. polyphylla var. chinensis was Bacillus, while the dominant groups in the diseased plant of P. polyphylla var. chinensis was Pseudomonas. The population diversity of the cultivable bacteria in healthy plant of P. polyphylla var. chinensis was more abundant than that of diseased plant.

Methyl parathion hydrolase (MPH, E.C.3.1.8.1) coding gene mph from Pseudomonas sp. WBC-3, isolated and identified by our lab, was successfully expressed in E. coli AD494 (DE3)/ pET32a(+) system as soluble fusion form at high level. The recombinant MPH showed nearly 4～5 fold higher specific activity to parathion than the enzyme from Pseudomonas sp. WBC-3. In addition, the thermal stability of the recombinant enzyme was improved comparing with the wild type enzyme.

Objective To compare and analyze the effect of prophylactic postoperative radiotherapy for esophageal carcinoma.Methods 102 such patients were treated with prophylactic radiotherapy after radical resection,to a total dose of 50-60 Gy.The extensive portal included supraclavicular region on both sides,entire mediastinum,the site of anastomosis and left gastric lymph node region in 43 patients.The re- gional portal range was different according to the different location of primary lesion in 59 patients.Results The 1-,3- and 5-year survival rate was 76%,51% and 43% respectively,with a median survival of 30 months.The 1-,3- and 5-year survival rate was 77%,52% and 41% in the extensive portal and 76%, 49% and 45% in the regional portal,respectively(P=0.884).According to multivariate analysis,N stage, number of metastatic lymph nodes and tumor length were independent prognostic factors.Conclusions Regional portal does not lower the survival rate when prophylactic postoperative radiotherapy is used in e- sophageal carcinoma.

OBJECTIVETo observe therapeutic effect of picking therapy on Graves' disease (GD) and its effects on thyroid function.

METHODSSixty cases of GD were randomly divided into a treatment group (pricking therapy group) and a control group (medication group). They were treated respectively with pricking thyroid gland high point or oral administration of tapazole. And changes of total triiodothyronine (TT3), total thyroxine (TT4), free T3 (FT3), free T4 (FT4), thyroxine receptor antibody (TRAb), supersensitive thyrotropin (S-TSH) after treatment were investigated.

RESULTSThe total effective rate was 93.33% in the treatment group and 76.67% in the control group with a significant difference between the two groups (P < 0.05). After treatment, serum TT3, TT4, FT3, FT4 and S-TSH contents had very significant change in the two groups (P < 0.01), TRAb had very significant change in the treatment group (P < 0.01) and no significant change in the control group (P > 0.05) there were significant differences in decrease of TT3, FT3, TRAb (P < 0.05) and no significant difference in decrease of TT4, FT4 and increase of S-TSH between the two groups (P > 0.05).

CONCLUSIONPricking therapy has a definite therapeutic effect on Graves' disease, which is carried out through regulating thyroid function.

OBJECTIVETo evaluate the effects of Caulis Sinomenii and sinomenine on conditioned place preference (CPP) induced by morphine and brain histamine level in mice.

METHODSSixty mice were randomized into 6 equal groups and morphine (Mor) was injected subcutaneously (9 mg/kg) for 6 consecutive days to induce CPP using a shuttle box. Since the 4th day of training, the mice in 5 of the groups were treated for 3 consecutive days with Caulis Sinomenii (10 g/kg), sinomenine (60 mg/kg), diphenhydramine (30 mg/kg), CP48/80 (5 mg/kg) and L-histidine (750 mg/kg) in addition to morphine (9 mg/kg) treatment, respectively, leaving the other group with exclusive morphine treatment. Another 10 mice received saline injection to serve as saline control group. The content of histamine (HA) in the mouse brain was measured by fluorospectrophotometry.

RESULTSIn morphine group, the mice showed significantly extended stay in morphine-paired compartment whose HA content in the brain was markedly increased (P<0.01). Treatment with Caulis Sinomenii and sinomenine resulted in significantly reduced time of stay in morphine-paired compartment and brain HA level (P<0.01).

CONCLUSIONCPP induced by morphine in mice is associated with increased HA level in the brain. Caulis Sinomenii and sinomenine can suppress the acquisition of place preference induced by morphine and modulate HA level in the central nervous system in morphine-dependent mice.

OBJECTIVETo investigate the diagnoses and treatment of interstitial cystitis (IC).

METHODSThe clinical data of 16 IC patients were analyzed respectively. The patients with urinary frequency, urgency, suprapubic pain and chronic pelvic pain. They were misdiagnosed as chronic cystitis, pelvic inflammation, endometriosis, cystophthisis and urethral syndrome, and were diagnosed finally by the means of pathology or cystoscopy. Among the 16 patients, 4 cases had the operation of ileal reservoir, Two cases had sigmoid-cysto-plasty, and 10 cases had drug treatment. The methods of IC diagnosis and treatment were discussed with the review of literature.

RESULTSThe pelvic ache disappeared completely in 4 cases after the operation of ileal reservoir; Two cases after cystoplasty felt lightly discomfortable in perineum occasionally, and their bladder capacity was above 350 ml, no recurrence after operation having been found after follow-up for 24 months and 33 months; Ten cases treated with non-operative treatment improved obviously, with the O'Leary-Sant IC symptom index and IC problem index decreased from 15.4 +/- 4.1, 9.4 +/- 2.7 to 4.1 +/- 2.1 and 5.1 +/- 3.9, respectively.

CONCLUSIONSSufficient attention should be paid to the diagnosis and differential diagnosis of IC; Early diagnosis and therapeutic alliance with manifold measures can relieve the patients' symptom and improve the quality of life.
