Con-clusion CT is the first choice in the diagnosis of pancreatic trauma. Master the CT symptom and make right diag-nosis, which were important to clinical operation.

Taxol is one of the most potent anti-cancer agents, which is extracted from the plants of Taxus species. Isopentenyl diphosphate isomerase (IPI) catalyzes the reversible transformation between IPP and DMAPP, both of which are the general 5-carbon precursors for taxol biosynthesis. In the present study, a new gene encoding IPI was cloned from Taxus media (namely TmIPI with the GenBank Accession Number KP970677) for the first time. The full-length cDNA of TmIPI was 1 232 bps encoding a polypeptide with 233 amino acids, in which the conserved domain Nudix was found. Bioinformatic analysis indicated that the sequence of TmIPI was highly similar to those of other plant IPI proteins, and the phylogenetic analysis showed that there were two clades of plant IPI proteins, including IPIs of angiosperm plants and IPIs of gymnosperm plants. TmIPI belonged to the clade of gymnosperm plant IPIs, and this was consistent with the fact that Taxus media is a plant species of gymnosperm. Southern blotting analysis demonstrated that there was a gene family of IPI in Taxus media. Finally, functional verification was applied to identify the function of TmIPI. The results showed that biosynthesis of β-carotenoid was enhanced by overexpressing TmIPI in the engineered E. coli strain, and this suggested that TmIPI might be a key gene involved in isoprenoid/terpenoid biosynthesis.

Cytochrome P450 oxidoreductase (POR) is the only electron donor for all microsome Cytochrome P450 monooxygenases which are phase I metabolizing enzymes responsible for the metabolism of more than 80% drugs used in clinic.Also,POR metabolizes some anti-tumor prodrugs directly.Therefore,the alteration in POR activity caused by the polymorphisms of POR gene will be of great clinical significance.This review summarizes the newest advancement on the effects of POR polymorphisms on drug metabolism.

2-Keto-L-gulonic acid (2-KLG), the precurcor of L-ascorbic acid synthesis, was prepared directly from D-glucose by tandem fermentation. In the first step fermentation Erwinia sp. SCB 247 translated D-glucose to 2,5-diketo-D-gluconate (2,5-DKG), which accumenlated 180 mg 2,5-DKG per ml in the broth. In the second step fermentation Corynebacterium sp. SCB 3058 reduced 2,5-DKG to 2-KLG, which accumulated 35 mg 2-KLG per ml in the broth. This reductive fermentation was obtained under aerobic conditions by adding a hydrogen donor such as glucose.The average yield of five batches fermentation was 56.3 mol%, from D-glucose to 2-KLG in 10 L fermentor.

Objective To evaluate the safety and efficacy of nephron sparing surgery for small renal tumor. Methods A total of 43 patients with small renal tumor underwent nephron sparing surgery (NSS). Of the 43 patients, 27 were male and 16 were female, with an average age of 46.0(21-79)years. The mean diameter of the tumors was 3.1 (1.2- 4. 0)cm. Eighteen cases received open NSS, other 25 cases received retroperitoneal laparoscopic NSS. The perioperative data and renal function, postoperative complications and tumor recurrence were evaluated. Results The procedure was successful in all 43 patients, though 2 cases occurred serious bleeding during operation. The average operating time was 158. 0(69- 277) and 150. 0(60-226) min in open NSS and laparoscopic NSS groups. The average warm ischemia time was 23. 2(20-31) and 25.8(23-35) min. The average blood loss was 590.8(120-3000) and 468. 5(50-1600) ml. The average pre-operation creatinine was (65.9±22. 8)and(68.4±25.0)μmol/L. The average creatinine at the end of follow-up was(82. 2±24.1)and(85. 3±25.9)μmol/L. The average hospital stay was 19.2(11-47) and 12.5(10- 16) (P＜0.05). The histological results showed 25 cases of renal cell carcinoma (RCC, Tla) and 18 cases of benign lesions. Sixteen cases(37%)of minor complications were observed. Comparing the open NSS versus laparoscopic NSS group, perirenal hematoma rate was 6 % vs 12 % (P＜0.05), flank numbness rate was 11.1% vs 0(P＜0.05). During the mean 25-60(37. 4±7.2)months follow-up, 1 case with RCC relapsed in 20 months and received radical nephrectomy. 1 case with harmatoma was found a new lesion apart from the original site in 6 months and CT scan confirmed harmatoma, and then received active surveillance. The 3-year recurrence-free survival for all tumors in 2 groups was 94%, 96%, and that for RCC was 100% and 93%, separately. Conclusions Comparing with open NSS, laparoscopic NSS for small renal tumor has a shorter hospital stay and lower flank numbness rate, though has higher perirenal hematoma rate. There was no significant difference in other complications between the 2 groups. No irreversible renal function damage was observed in two groups. The tumor recurrencefree survival and RCC recurrence-free survival were no significant difference between two groups.

Purpose To investigate the clinical value of three-dimensional hysterosalpingo-contrast-sonography (3D-HyCoSy) in the assessment of fallopian tubal patency.Materials and Methods Fallopian tubal patency of 33 infertile women was assessed using transvaginal 3D-HyCoSy, and the results were compared with laparoscopically salpingoraphy, the sensitivity, specificity, positive likelihood ratio and negative likelihood ratio of 3D-HyCoSy were evaluated.Results 3D-HyCoSy showed 20 passable fallopian tubes, 10 partially passable fallopian tubes and 36 obstructed tubes, while lapascopically salpingoraphy showed 23 passable fallopian tubes, 7 partially passable fallopian tubes and 36 obstructed tubes. The total coincidence rate of 3D-HyCoSy to assess the fallopian tubal patency was 86.4% (57/66), with the sensitivity of 93.0% (40/43), specificityof 73.9% (17/23), positive likelihood ratio of 7.15, and negative likelihood ratio of 0.20.Conclusion Tubal patency can be efficiently and accurately assessed using 3D-HyCoSy, but patients with obstructed or partially passable fallopian tubes should undergo laparoscopy to clarify.

Atropa belladonna L. is the officially medicinal plant species and the main commercial source of scopolamine and hyoscyamine in China. In this study, we reported the simultaneous overexpression of two functional genes involved in biosynthesis of scopolamine, which respectively encoded the upstream key enzyme putrescine N-methyltransferase (PMT; EC 2.1.1.53) and the downstream key enzyme hyoscyamine 6beta-hydroxylase (H6H; EC 1.14.11.11) in transgenic hair root cultures of Atropa belladonna L. HPLC results suggested that four transgenic hair root lines produced higher content of scopolamine at different levels compared with nontransgenic hair root cultures. And scopolamine content increased to 8.2 fold in transgenic line PH2 compared with that of control line; and the other four transgenic lines showed an increase of scopolamine compared with the control. Two of the transgenic hair root lines produced higher levels of tropane alkaloids, and the content increased to 2.7 fold in transgenic line PH2 compared with the control. The gene expression profile indicated that both PMT and H6H expressed at a different levels in different transgenic hair root lines, which would be helpful for biosynthesis of scopolamine. Our studies suggested that overexpression of A. belladonna endogenous genes PMT and H6H could enhance tropane alkaloid biosynthesis.

Objective To explore the expression of miR-221/222 in non-small cell lung cancer (NSCLC) and its correlation with clinical pathological parameters. Methods The clinical pathological data and formalin fixed-paraffin embedded (FFPE) tissues of 55 NSCLC patients and 10 benign lesion patients who underwent surgery in the First Affiliated Hospital of Nanhua University from February 2012 to May 2014 were collected and followed. The relationship between miR-221/222 expression detected by real-time PCR and clinical pathological parameters and progression-free survival (PFS) were analyzed. The differential survival between the high expression group and the low expression group of miR-221/222 were compared. A Cox proportional hazard regression model was utilized to examine the prognostic factors of NSCLC. Results The expression level of miR-221/222 was significantly higher in tumor tissues than that in corresponding benign lesion tissues (Fold change=3.52, P=0.000;Fold change=2.01, P=0.000). There was a negative correlation between miR-221/222 expression and pathological grades (r=-0.732, P=0.000;r=-0.451, P=0.001). The relative expression of miR-221 showed a positive correlation with miR-222 (r=0.376, P=0.000). Patients with higher levels of miR-221/222 were closely associated with a shorter PFS (miR-221: 55.43 weeks vs. 81.29 weeks, P=0.028; miR-222: 45.00 weeks vs. 87.04 weeks, P=0.008). Finally, multivariate analysis demonstrated that miR-222 expression was independently associated with poor PFS (RR=2.808, P=0.033). Conclusions miR-221/222 is highly expressed in NSCLC tumor tissues with a positive correlation. A negative correlation is observed between the expression of miR-221/222 and tumor differentiation. The potential high expression of miR-221/222 is considered as tumor biomarkers for the prognosis of NSCLC patients.

Objective: To discuss the diagnosis and treatment of infantile congenital subglottic hemangioma. Method:Nine patients with recurrent stridor,feeding difficulties and laryngeal obstruction were diagnosed as con-genital subglottic hemangioma with bronchia endoscopy. The lesions were unilateral in 7 cases and bilateral in 2 ca-ses. Eight cases were treated by intralesional Pingyangmycin injection after tracheotomy. Patients were discharged with metal trachea and were followed up endoscopically 2 weeks thereafter. A second treatment would be required if the tumor reduced in size but not disappeared completely. Plugging tubes and extubation would be done when the tumor disappeared completely. One case with unilateral lesion underwent power-assisted tumor resection with-out tracheotomy. Result: Hemangioma vanished completely in 6 patients with unilateral subglottic hemangioma who were treated with single stage procedure. Tumor size was found reduced significantly after one procedure and van-ished completely after a second procedure in 2 cases with bilateral subglottic hemangioma. All of the 8 cases were extubated successfully. The patient recovered thoroughly in two weeks after power-assisted tumor resection. Con-clusion: Intralesional Pingyangmycin injection after tracheotomy can relief the airway obstruction quickly, shorten the nature course of hemangioma, shorten the period of wearing trachea, has no complication such as subglottic stenosis and is thought to be a safe and effective therapy for large size hemangioma. Power-assisted tumor resec-tion under good total anesthesia without tracheotomy combined with well hemostasis is effective, less injure, and suitable for small size hemangioma.
