OBJECTIVETo compare the efficacy difference in the treatment of functional dyspepsia between acupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone.

METHODSSeventy cases were randomized into an acupuncture group (35 cases) and a western medication group (35 cases). In the acupuncture group, Zusanli (ST 36) and Neiguan (PC 6) were selected. Taichong (LR 3) and Neiting (ST 44) were added for excess syndrome while Gongsun (SP 4) and Yinlingquan (SP 9) were added for deficiency syndrome. A pair of electrodes was attached to one acupoint and an assistant point (2 mm next to the acupoint centripetally) and stimulated with disperse-dense wave at 2 Hz/100 Hz, once a day. In the western medication group, domperidone was prescribed for oral administration, 10 mg each time, three times a day. In the two groups, the treatment of 5 days made one session and 4 sessions were required totally. Nepean dyspepsia index (NDI) was compared after treatment, 1, 2, 3, 4 and 5 months after treatment between the two groups respectively.

RESULTSThe score of symptom and score of life quality in NDI after treatment and at each follow-up time point were improved obviously in the acupuncture group as compared with those before treatment (all P < 0.01). In the western mediation group, the score of symptom and the score of life quality in NDI after treatment and in follow-up of 1, 2 and 3 months were improved obviously as compared with those before treatment (all P < 0.01), but the differences were not significant in follow-up of 4 and 5 months (both P > 0.05). Compared with the western medication group, the symptom score of NDI was reduced obviously after treatment and in each time point of follow-up in the acupuncture group (P < 0.05, P < 0.01), and the score of life quality was increased obviously (P < 0.05, P < 0.01).

CONCLUSIONAcupuncture at the acupoints selected by pattern/syndrome differentiation and domperidone are effective in the treatment of functional dyspepsia. Domperidone is unsatisfactory in the long-term effect, but acupuncture achieves the positive short-term and long-term effects on functional dyspepsia.

Objective To predict the binding sites of transforming growth factor-βreceptor Ⅱ (TβRⅡ ) ectodomain and the aptamer S58 specifically targeted TβRⅡ ,and to confirm the structure stability of the aptamer S 58 in vitro .Methods We created three-dimensional structure by utilizing ssDNA aptamer sequences ,the crystal structure of the TβRⅡ was searched by protein data bank database .According to the results of the molecular docking experiments on aptamer S 58 and TβRⅡ ectodomain ,we sheared the aptamer sequences ,then verified its affinity respectively by biosensor technology and Western blot .Results Binding sites of aptamers S58 and TRβⅡ ectodomain included site Ⅰ(T4 ,T5 ,G6 ,C7) ,site Ⅱ(G13 ,A14 ,T15 ,C16 ,G17 ,C18 ) ,site Ⅲ (T31 ,G32 , T33 ,C34) and site Ⅳ(G40 ,A41 ,T42 ,T43 ,T44 ,G45 ,G46) .We validated the high affinity between aptamer S58 and TRβⅡ ectodo-main .The expression of α-smooth muscle actin(α-SMA) protein in the human tenon′s capsule fibroblasts was descended obviously after the experiment of the aptamer S58 in comparing with the control of DMEM (P< 0 .05) .But the new ssDNA by shear the aptamer ssDNA S58 according to the results were poor than aptamers S58 .Conclusion The aptamer S58 targeted TβRⅡ was high-ly specific with a certain stability ,any changing of structure will reduce the affinity of TβRⅡ .Computer-aided molecular docking technology has become an important means of an exploratory intermolecular interaction ,and can provides a good theoretical basis on medical research .

Twenty-five compounds of novel quinoxaline-based scaffold with antiplatelet activity were designed and synthesized on the basis of previous quinoxaline analogues, and the structures were confirmed by ¹H NMR, ¹³C NMR, and MS. The antiplatelet activity was evaluated, structure-activity relationship (SAR) study was summarized and the selectivity of PAR4 was confirmed by calcium mobilization assays. It was indicated that compound 14a, 14g, 13i, 13p showed moderate activity against PAR4, especially, the activity of compound 14g (IC₅₀ = 0.26 μmol·L^-1) was 6.7 times than the lead compound A (IC₅₀ = 1.73 μmol·L^-1). Therefore, 2,3-dihydro-[1,4]dioxino[2,3-g]quinoxaline and [1,3]dioxolo[4,5-g]quinoxaline derivatives are promising compounds for the discovery of novel antiplatelet agents. It is worthy of further research to develop highly effective and selective PAR4 antagonists.

Objective To observe the clinical efficacy of balance acupuncture predominantly by puncturing Jiaji points (EX-B2) from C4 to T1and from T12 to L1in treating hemiplegic balance disturbance after cerebral stroke. Method A total of 180 hemiplegia patients were randomized into 3 groups, 60 cases in balance acupuncture group, 60 cases in ordinary acupuncture group, and 60 cases in basic control group. After 1-month treatment and 3 months after the treatment, the motor function (Fugl-Meyer Assessment, FMA), balance function (Berg Balance Scale, BBS; Timed Up and Go Test, TUGT), and activities of daily living (ADL) (Barthel Index, BI) were observed.Result After 1-month treatment and 3 months after the treatment, limb function, balance ability and ADL were significantly different from those before the treatment in balance acupuncture group (P<0.01); after 1-month treatment, limb function in balance acupuncture group was significantly different from that in basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01); there were significant differences between ordinary acupuncture group and basic control group (P<0.05). Three months after the treatment, there was a significant difference in comparing balance function between balance acupuncture group and basic control group (P<0.05), and the differences were more statistically significant in comparing the rest indexes between the two groups (P<0.01), there was no significant difference in comparing balance function between ordinary acupuncture group and basic control group (P>0.05).Conclusion In combination with basic treatment, balance acupuncture works better than ordinary acupuncture and basic control in improving limb function, ADL and balance function of hemiplegia patients.

OBJECTIVETo evaluate the impact of spermatozoa from different sources on normal fertilization of oocytes, embryo quality and embryo developmental potential in intracytoplasmic sperm injection (ICSI) cycles.

METHODSA retrospective analysis was conducted among 197 patients undergoing ICSI cycles in our center. The patients were classified into 3 groups according to the sources of semen, namely ejaculated spermatozoa group (n=102), percutaneous epididymal sperm aspiration (PESA) group (n=68), and testicular sperm aspiration (TESA) group (n=27). The ejaculated spermatozoa group was further classified into oligoasthenoteratozoospermia (n=67) and cryptozoospermia (n=35) subgroups. The normal fertilization, high-quality embryo, implantation and clinical pregnancy rates were compared among the groups; the rate of high-quality blastocyst formation in in-vitro culture of non-top quality embryos was also observed.

RESULTSThe patients with PESA showed significantly higher normal fertilization rate (75.6%) than those in oligoasthenoteratozoospermia (64.8%), cryptozoospermia (62.1%), and TESA (61.6%) groups (P<0.05). No significant differences were found in the high-quality embryo, implantation, and clinical pregnancy rates among the groups (P>0.05). The rate of high-quality blastocyst formation in the in-vitro culture of non-top quality embryos was also comparable among the groups (P>0.05).

CONCLUSIONAlthough spermatozoa obtained with by PESA is associated with a higher normal fertilization rate, the sources of spermatozoa do not significantly affect the embryonic quality and developmental potential in ICSI cycles.

OBJECTIVETo discuss the best surgical approach to the skull base neoplasms.

METHODSRetrospective analysis the 79 skull base neoplasms cases treated with surgical resection in Qilu hospital of Shandong university from 1992 to 2002. Eleven surgical approaches including midfacial degloving, frontal coronal discission, nasal eversion, maxillary swing, partial maxillary resection, total resection of orbit, mandibular swing, combination of front, temple, preauricular, post aureum, neck, and transoral approaches were used to resect the tumor which involved fossae pterygopalatine, paranasal sinuses, nasopharynx, antero, meso and posterobasilar region, lobi frontalis and lobi temporalis of cerebrum.

RESULTSSeventy-nine skull base neoplasms were totally removed and no one died from the operation. Although 5 cases complicated with cerebrospinal fluid leak and all recovered within 1 week, no serious cranium-cerebrum complication occurred. In 29 patients with benign tumor including 11 cases of meningioma, 3 cases of chondroma, 1 case of hemangio-meningioma, 1 case of cavernous hemangioma, 2 cases of osteodysplasia fibromas, 9 cases of neurofibroma, 1 case of glomus jugular tumor, 1 case of neurilemmoma, 19 have survived over 5 years and the longest one has survived over 8 years. For 50 patients with malignant tumor including 3 cases of well-differentiated squamous cell carcinoma, 17 cases of moderately differentiated squamous cell carcinoma, 11 cases of poorly differentiated squamous cell carcinoma, 1 case of undifferentiated carcinoma, 2 cases of chondrosarcoma, 5 cases of canceration of papilloma, 2 cases of adenocarcinoma, 1 case of esthesioneuroblastoma, 2 cases of malignant fibrohistiocytoma, 1 case of fibrosarcoma, 2 cases of malignant mixed tumour, 3 cases of sarcoma survival rates of 3 and 5 years were 59.2% (29/49), 38.5% (10/26) respectively.

CONCLUSIONIn order to resect the tumor completely and reduce the complication and malformation as far as possible, different surgical approaches must be designed according to the pathological changes characters and involved area,and the surgeon should select the shortest approach, avoid to damage the important neurovascular structure, and resect the tumor through the natural anatomy space by the shelter incision.

OBJECTIVETo explore the feasibility and the related surgical techniques of laryngeal function preservation in surgical treatment of pyriform sinus cancer.

METHODSTwo hundred and thirty cases (stage I, 6; stage II, 10; stage III, 91; stage IV, 123) with pyriform sinus cancer were treated surgically from 1978 to 1996 in the Department of Otorhinolaryngology of Qilu Hospital of Shandong University. The methods of removing tumor and repairing surgical defects were depended on the extension of lesions. The laryngeal and pharyngeal functions were rebuilt by normal tissue preserved with lesions entirely removed. One hundred and fifty-eight cases were surgically treated with laryngeal functions preserved and 72 cases total laryngectomy. The most of the cases received postoperative radiotherapy.

RESULTSThe overall 3 and 5 year survival rates were 67.4% (155/230) and 48.3% (111/230) respectively. For stage I, the survival rate was 5/6; stage 11, 70.0% (7/10); stage III, 57.1% (52/91) and stage IV, 38.2% (47/123); the 3 and 5 year survival rates in functionally preserved group were 67.7% (107/158) and 50.0% (79/158), while in none functional group were 66.7% (48/72) and 43.1% (31/72), respectively. 75.3% (119/158) patients have laryngeal functions (voice,respiration and deglutition) completely restored and 24.7% (39/ 158) partially restored(voice and deglutition).

CONCLUSIONSThe preservative surgery is feasible for the selected pyriform sinus cancer cases. Choosing and following optimum surgical methods is a prerequisite for improving the quality of life of the cases.

L-sorbose/L-sorbosone dehydrogenase from Ketogulonigenium vulgare S2 can transform L-sorbose to 2-KLG, which is widely used in production of Vitamin C. In order to obtain the engineering strain producing L-sorbose/L-sorbosone dehydrogenase and simplify the fermentation technology, firstly, this enzyme was purified by the methods of ammonium sulfate precipitation, DEAE Sepharose Fast Flow and Q Sepharose High Performance. Then, the purified L-sorbose/L-sorbosone dehydrogenase was injected to rabbit to obtain antibody. Next, the genomic library of Ketogulonigenium vulgare S2 was constructed by inserting the restriction fragments of chromatosomal DNA digested with Sau3A I into cosmid pKC505 vector digested by Hpa I and Pst I, which were packed with lamda phage package protein and transferred into E. coli DH5alpha in vitro. Finally, the positive strain K719# was selected from more than 12,000 clones via Dot-ELISA. Through the test of SDS-PAGE and thin layer chromatography, the results showed that the engineering strain K719# had the same biological activity as Ketogulonigenium vulgare S2 after adding coenzyme PQQ.
