ObjectiveTo explore the effects of optional cesarean section on the level of plasma motilin and serum gastrin in umbilical blood and their relationship with gastroenteric symptoms of neonates. MethodsWe measured the concentrations of plasma motilin and serum gastrin in umbilical blood from neonates undergoing optional cesarean operation, emergency cesarean section and vaginal delivery by radioimmunoassay(RIA). ResultsFull-term deliveries undergoing optional cesarean section were with significant gastrointestinal symptoms. Plasma motilin and serum gastrin were significantly lower in neonates undergoing cesarean operation without birth initiate group(optional cesarean section)than that in cesarean section with birth initiate group and vaginal delivery group (P<0.05). ConclusionCesarean operation without birth initiate influences neonatal gastroenteric symptoms.Breast feeding which begins as early as possible will help to relieve those symptoms.

Objective:To assess the clinical efficacy of two different diameter Osstem MS one-stage implant restoration of small edentu-lous space in the mandibular anterior region.Methods:85 patients were treated by Osstem MS one-stage implant with the diameter of 2.5 mm(n =66)and 3.0 mm(n =66)respectively for the restoration of small edentulous space in mandibular anterior region.The mesi-al and distal marginal bone level and soft tissue were statistically analyzed after 1 2 and 24 months of functional load.The implant survival rate was evaluated according to Wheeler's survival criteria.Results:The survival rate of the implants was 1 00%.The mean changes in marginal bone level(mm)on the mesial side of 2.5 mm and 3.0 mm diameter implants were 0.275 ±0.638 and 0.098 ±0.31 9,distal aspects were 0.360 ±0.588 and 0.1 09 ±0.323 after 1 2 months of functional load;while 0.299 ±0.672 and 0.099 ±0.31 8,0.381 ± 0.581 and 0.1 07 ±0.31 9 after 24 months of functional load.The mesial and distal marginal bone loss of 2.5 mm diameter implant was greater than that of 3.0 mm after 1 2 and 24 months of functional load(P <0.05).No significant change on the marginal bone level was found aomog the same diameter implants from 1 2 to 24 month observation(P >0.05).No relevant complication of peri-implant soft tissue was shown.Conclusion:Favorable clinical effects including function and aesthetics can be achieved by Osstem MS one-stage implant with the diameter of 2.5 mm or 3.0 mm for the restoration of small edentulous space in the mandibular anterior region,however,the mar-ginal bone loss was greater around 2.5 mm diameter implant.

Objective To compare the serum index after colonoscopy high-frequency electric snare combined with nylon cord ligation and high-frequency electric resection in treating broad pedicle polyps. Methods 70 cases of broad pedicle polyps patients from July 2012 to May 2016 were chosen as research object. The operation methods and laboratory examination results of all the patients were reviewed. All patients were divided into observation group (n = 37) and control group (n = 33). Patients in observation group were treated by colonoscopy high-frequency electric snare combined with nylon loop ligation, while patients in control group were treated by high-frequency electric resection only. The blood loss and related indexes of the two groups were recorded. Before and after operation, stress hormones and acute phase proteins in serum was determined. Results Intraoperative blood loss of observation group was less than that in control group, postoperative hemoglobin levels was higher than that in control group, postoperative early bleeding rate, postoperative delayed bleeding rate of observation group were lower than that in control group (P < 0.05); 1 hour after surgery, Cor, ACTH, AT II, NE, CRP, SAA, AAT in serum were lower than those in control group (P < 0.05). Conclusion Through colonoscopy high-frequency electric snare combined with nylon cord ligation can reduce bleeding during and after surgery, relieve stress and inflammation.

Objective To study the clinical effect, safety of stains collapse of traditional Chinese medicine (TCM) combined with tumor necrosis factor-alpha (TNF-α) antagonist-a recombinant human tumor necrosis factor receptor:Fc fusion protein (rhTNF:Fc) and sulfasalazine (SSZ) in treatment of active ankylosing spondylitis (AS). Methods A total of 98 patients of AS of Gansu Provincial Hospital were divided into two groups in random, the western medicine group (rhTNF:Fc and SSZ, n=46) and the combining group (stains collapse of TCM, rhTNF:Fc and SSZ, n=52). The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), Patient Global Assessment (PGA), Visual Analogue Scale (VAS) of night pain, VAS of total pain, time of morning stiffness, TCM symptom score, distance between occipital and wall, distance between finger and ground,
thoracic activity, Schober test, and erythrocyte sedimentation rate (ESR), C reactive protein (CRP), adverse reactions before and after treatment were observed and the clinical effect was evaluated in two groups. Results A total of 86 patients achieved the study finally, 45 patients in the combining group and 41 patients in the western medicine group. The effective rate of ASAS20 was better in the combining group than that in the western medicine group(χ2=4.814,P=0.028), the Bath ankylosing spondylitis disease activity index (BASDAI) 50 showed no significant difference between the two group (χ2=0.100,P=0.752). The total effective rate in the combining group than that in the western medicine group(χ2=3.873,P=0.049). In comparison with the same group before treatment, the above indicators were improved after treatment (P<0.05). In comparison with the western medicine group after treatment, BASFI, PGA, VAS of night pain, VAS of total pain, time of morning stiffness, TCM symptom score, distance between occipital and wall, distance between finger and ground and Schober test were getting better in the combining group (P<0.05), but BASDAI, thoracic activity, ESR, CRP were not improved in the combining group (P>0.05). The adverse reactions showed no significant difference (P>0.05). Conclusions Stains collapse of TCM combined with rhTNF:Fc was more effective than single method in treatment of AS, it can alleviated the symptoms, body signs and body function, decrease indexes of inflammation, which has dramatic effect and good safety in clinic.

Objective To compare the effect on intraoperative cerebral metabolism between the propofol combined with remifentanil infusion in total intravenous anesthesia and the desflurane combined with remifentanil intravenous inhalation anesthesia in patients in neurosurgery.Methods Thirty-four patients were randomly divided into the propofol combined with remifentanil group (group A,n=16) and the desflurane combined with remifentanil group (group B,n =18).The B-ultrasound under the guide of retrograde catheterization through right internal jugular vein and artery was prepared after the patients entered the operation room.Atropine,propofol,fentanyl,rocuronium were used in the induction of anesthesia.The mechanical ventilation was applied after conventional trachea cannula.Once patients were anesthetized steadily,jugular bulb venous oxygen saturation (SjvO2),jugular bulb venous oxygen partial pressure (PjvO2),Jugular Bulb venous hemoglogin (Hbv),jugular bulb venous lactate (Ljv),jugular bulb venous gluxose (Gv),arterial oxygen saturation (SaO2),arterial oxygen pressure (PaO2),arterin (Hba),arterial blood lactate (La),arterial blood gluxose (Ga),arterial blood oxygen content (CaO2),jugular bulb venous oxygen content (CjvO2),arteriovenous oxygen difference (AVDO2),cerebral extraction of oxygen (CEO2),cerebral lactate production rate (CLP) and cerebral glucose uptake rate (CGU) at different time [before anesthesia induction (T1),1 hours after the start of the operation (T2),2 hours after the start of the operation (T3),half an hour after the operation]were collected.Results (1) The value of SjvO2,PjvO2,CjvO2 and CaO2 in group B was significantly higher than that in group A (P＜0.001);The value of AVDO2 and CEO2 in group B was lower than that in group A (P＜0.05);(2) The value of Gv and Ga in group B was higher than that in group A (P＜0.05);There were no significant differences about CGU in two groups (P＞0.05);(3) The value of CLP in group B was lower than that in group A (P＜0.05);there were no significant differences about Ljv and La in two groups (P＞0.05);(4) Compared with the value at moment of T1 between group A and group B,the value ofPaO2,SaO2,PjvO2 and SjvO2 were increased with time (P＜0.05),the value of CaO2,CjvO2,AVDO2 and CEO2 showed a downward trend (P ＜0.05).Conclusion (1) Both total intravenous anesthesia and intravenous inhalation anesthesia can reduce the cerebral oxygen metabolism;(2) For the cerebral protection of neurosurgery operation,it seems that the effect of intravenous inhalation anesthesia is more stronger than total intravenous anesthesia.

Objective To investigate the menstruation status of reproductive age women of Han Nationality in Liaoning province. Methods From Apr. 2008 to Dec. 2008, 1611 women at age of 19-45 years from Shenyang, Yingkou, Benxi, Zhangwu were enrolled in this study according to epidemiologic cluster sampling method. The study was performed by questionnaire consisting of age of menarche, regularity of menstruatinn, menstrual cycle and dysmenorrhea, et al. Results In the survey of 1611 women, the average menarche age is 14.4 years old, there were significant difference on menarche between (14.2±1.5) years in women from city and (14.6±1.5) years in women from country (t=6. 58, P<0.01). The linear regression statistic method was used to analyze the relationship between age and menarehe age, the linear regression equation was gotten as Y=0. 074X+11. 855, which means 1 year increase was associated with decrease by 0.074 years in mennrche age approximately. About 86.34% (1391/1611) of women have normal and regular menstrual cycle at range of 21 to 35 days, while 11.05% (178/1611) of women have longer menstrual cycle(>35 days) and 2.61% (42/1611) of women have shorter menstrual cycle (<21 days). Of which 65.67% (1058/1611) women have regular menstrual cycle just after menarche, 94. 97% (1530/1611) of women would have regular menstruation in 2 years after menarche. The rate of dysmenorrhea was 42.09% (678/1611), of which 13.6% (92/678) women have high severe pelvic pain.Conclusion Our results suggested that the trend went toward younger ages of menarche,which was younger menarche age in women from city than country. About 95% women would have regular menstrual cycle within 2 years after menarcbe.

Objective To analyse the location of the mandibular canal,providing the theoretical basis for implanting and bone grafting. Methods Mandibular data of 83 Chinese people obtained by cone-beam computed tomography examination were collected. Results The distance from the mandibular canal to mandibular buccal wall was (5.32 ± 1.29)~(7.24 ± 1.29) mm. And the average distance from mandibular canal to mandibular lingual wall or inferior margin were respectively (3.43 ± .99) ~ (3.93 ± 1.17) mm and (8.81 ± 1.90) ~ (10.02 ± 2.19) mm. Significant differences between males and females were found in groups. The anterior loop was observed in 70.9%of all sides. The accessory mental foramen was observed in 10.84% of all sides. Conclusion For the remarkable mutation of the location of the mandibular canal in Chinese people, clinicians should be careful before implant or bone surgery procedures to minimize the risk of inferior alveolar nerve injury.
