Two parental strains BY-14 and BY-6,with high leavening ability in lean and sweet dough respectively,were selected.Through spore production and separation,two haploids with opposition types were selected for cross-breeding.At last one hybridization strain was obtained,with good fermentation ability as BY-14 in lean dough and better than BY-6 by 25%in sweet dough.

OBJECTIVETo observe the effect of using polytetraflouroethylene (e-PTFE) tube with self-Schwann cells implanted to repair facial nerve defect.

METHODSEnzymatic digest method was used to get pure Schwann cells in short time. The e-PTFE membrane tube was used to bridge the 1.0 cm defect of facial nerve and pure self-Schwann cells were injected into the tube. As control group, the e-PTFE tube without self-Schwann cells was used in the same way. Electric physiological and histological examinations were taken in different times.

RESULTSThe effect of nerve regeneration of the experimental group was better than control group at any time. The nerve conduction velocity of the experimental group was 29.70 m/s in the 16th week, while the control groups was 23.00 m/s respectively at the same time.

CONCLUSIONIt is possible to obtain sufficient active Schwann cells by enzymatic digest method. Using e-PTFE tube to bridge the defect of facial nerve with self-Schwann cells implanted can get effect of nerve regeneration.

OBJECTIVE:To observe the clinical efficacy and safety of recombinant human endostatin (rh-endostatin) combined with Lobaplatin for injection and irinotecan injection in the treatment of advanced recurrent small cell lung cancer (SCLC). METHODS:A total of 88 patients with advanced recurrent SCLC in our hospital were divided into control group (41 cases) and observation group (47 cases) according to random number table. Control group was given Irinotecan injection+Lobaplatin for injection. Observation group was additionally given Recombinart human endostatin injection 15 mg added into 0.9%Sodium chloride injection 250 mL,ivgtt,qd,for consecutive 14 d,every 14 d. A treatment course lasted for 28 d,and both groups were treated for 2 courses. The clinical efficacy,the levels of serum carcinoembryonic antigen(CEA),the scores physical state (ECOG) and quality of life (QOL) before,after treatment were observed in the two groups,and the survival and adverse reactions of the two groups were compared. RESULTS:The total response rate of observation group was 59.6%,which was higher than 43.9% of control group,but there was no statistical significance (P>0.05). Before treatment, there was no significant difference in serum CEA levels,ECOG scores or QOL scores,between 2 groups(P>0.05);after treatment,the serum CEA levels of the two groups were significantly decreased,and the observation group was significantly lower than the control group,with statistically significant (P<0.05). In observation group,ECOG scores decreased while QOL scores increased significantly,and significantly better than the control group,with statistical significance(P<0.05). The overall survival(OS)of observation group was 16.8 months,which was significantly higher than 11.5 months of control group,with statistical significance (P<0.05). The incidence of leucopenia in observation group was significantly higher than control group;the incidence of leucopenia and abnormal liver function were significantly lower than control group,with statistical significance(P<0.05). CONCLUSIONS:Rh-endostatin injection combined with lobaplatin and irinotecan can improve serum CEA levels and the quality of living aswell as prolong the survival time.

The conception,sources and research focus on environmental estrogens of effluent from sewage treatment plants were briefly introduced and the advances on environmental estrogens of effluent from sewage treatment plants were reviewed in the present paper.The study and applications of biomarker-vitellogenin (Vtg) was also discussed.The future research direction of environmental estrogens was proposed.

ObjectiveTo compare the efficacy and side effects of ilioinguinal/iliohypogastric nerve blockades and rectal paracetamol after pediatric inguinal hernia repair.MethodsNinety children undergoing half inguinal hernia repair were randomly divided into 3 groups:nerve block group(n=30),paracetamol group(n=30) and control group(n=30).After basal anesthesia,ilioinguinal/iliohypogastric nerve blockades was administed in nerve block group,paracetamol group received rectal paracetamol,control group had not any medication.Every child was oberserved 1,3,6,8 h postoperatively for pain score,overall satisfaction were evaluated by parents,furthermore,evaluation of distress for children such as nausea,vomiting and delayed femoral nerve palsy was made.ResultsPain scores were significantly lower in nerve block group and paracetamol group during the postoperative follow-up 1,3 and 6 h.Overall satisfaction in nerve block group and paracetamol group were significantly higher than control group.The incidence of delayed femoral nerve palsy in nerve block group was higher than paracetamol group(F=4.22P

AIM: To evaluate the efficacy of combined therapy for amblyopia in children by making use of pattern visual evoked potential ( P-VEP) game.
METHODS: This was a prospective case control study. These asthenopic children were divided into two groups. The control group ( 66 eyes of 49 patients ): occlusive therapy with glasses, cover, precision work, red light treatment and so on, later the stereo vision training was added. The experimental group (72 eyes of 52 patients):conventional methods mentioned above with P - VEP games.
RESULTS: The total effective rate and cure rate of experimental group in 6mo were higher than those of control group. The overall effective rate was 94. 4% in the experimental group and 83. 3% in the control group. There was a statistically significant difference between them (P<0. 05).
CONCLUSION: The comprehensive therapy by making use of P-VEP game is an individualized effective new way in treating amblyopia.

To discuss the effective method of decreasing the postoperative recurrence rate of recurrent pterygium.
●METHODS:Totally 126 cases (126 eyes) with recurrent pterygium were randomly divided into A group (56 cases) and B group ( 70 cases ). Group A was treated by pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation, group B was treated by amniotic membrane transplantation. The followed-up time after surgery was 6-24mo.
●RESULTS:ln group A, postoperative 5-7d (average 5. 62± 1. 38d), cornea epithelium was repaired. ln group B, postoperative 7- 10d ( average 7. 38 ± 1. 12d), the corneal wound was healed. There was statistical significant difference between two groups (t = 4. 307,P<0. 05). Three cases recurrence were noted in A therapeutic group (56 cases), the recurrent rate was 5. 4%; Twelve cases recurrence were noted in B compared group (70 cases), the recurrent rate was 17. 1%. There was statistical significant difference between two groups(P<0. 05).
●CONCLUSlON: lt is suggested that pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation is effective in the treatment of recurrent pterygium.

The effects of ultrafine grinding on the dissolution rates of the effective components in Sanjie Zhentong capsule (SZC) were studied in this experiment. Fine and ultrafine powder of SZC intermediates were made by ordinary grinding and ultrafine grinding technology, and then granulated by wet granulation. SZC were prepared by fine powder, ultrafine powder and ultrafine granules, respectively. With resveratrol and loureirin B as investigated indexes, dissolution rates of the four intermediates in SZC were determined by cup method and HPLC. The dissolution rates of resveratrol in SZC prepared by fine powder, ultrafine powder and ultrafine granules were 26.11%, 63.27%, 67.49%, respectively; and the dissolution rates of loureirin B were 7.160%, 20.29%, 23.05%, respectively. The dissolution rate of resveratrol and loureirin B in SZC prepared by ultrafine granules was the best. D90 size of ultrafine grinding was 13.221 μm and could improve the dissolution rates of resveratrol and loureirin B in SZC.
