Objective To study the clinical effects of tearing pediatric diarrhea with traditional Chinese and western medicine.Methods Altogether 520 patients with pediatric diarrhoea were recruited into three groups:the group treated with combined traditional Chinese and western medicine,the group treated with Chinese medicine and the group treated with western medicine.Observe clinical effects of each group.Results In 175 cases of the group treated with combined traditional Chinese and western medicine,66 cases show significant effects,64 cases are effective,45 eases are ineffective,and the effective rate is 74.30%;In 171 cases of the group of treated with traditional Chinese medicine,32 eases show significant effects,42 eases are effective,97 cases are ineffective,and the effective rate is 43.30%;In 174 eases of the group of treated with western medicine,35 eases show significant effects,43 eases are effective,96 eases are ineffective,and the effective rate is 44.80%.The effective rate of the group treated with combined Chinese medicine and western medicine was significantly better than the other two groups (P＜0.01).Conclusion Combined Chinese and western medicine is more effective in treating the patients with pediatric diarrhea,and it is worthy of spread.

Objective To discuss the liver function recovery affected by the portal vein flow in patients who underwent adult-to-adult living donor liver transplantation using the right lobe. Methods Seventy-four donors and recipients were included in this study. Intraoperative Doppler ultrasound (IOUS)were performed before splitting the donor liver and 1 hour after the graft reperfusion. The diameter and velocity of portal vein were measured and recorded for calculation of portal vein flow(PVF). Liver function tests were undertaken at the day 2nd,7th, 15th and 30th postoperative,respectively. Results One hour after reperfusion of 74 grafts,the PVF were significantly increased (2. 84 ± 0. 93) fold. Seventy-four grafts were divided into 4 groups according to the different degrees of the increase of PVF. The levels of blood bilirubin total(TBIL) among 4 groups were differently at the day 2nd,7th, 15th and 30th postoperative. High PVF contributed to recipient's prolonged hyperbilirubinemia ( P ＜0. 001 ). The levels of ALT, AST among 4 groups were differently at the day 7th, 15th and 30th postoperative( P ＜0. 001). Conclusions Detection of portal vein hemodynamics in living donor liver transplantation by IOUS may assist surgeon to anticipate the graft's function and take surgical therapies to secure the graft and the recipient.

OBJECTIVE: To analyze the recurrencerelative factors of early glottic carcinoma after carbon dioxide laser treatment. METHOD: A retrospective analysis of 134 early glottic carcinoma patients' clinical data was taken to analyze the relationships between recurrence and gender, age, pathologic degree, T stage, involvement of anterior commissure and involvement of thyroarytenoid muscle. RESULT: Recurrent ratio of well-differentiated, middle-differentiated and poorly-differentiated squamous cell carcinoma were 11.83%, 18.42% and 33.33% (P > 0.05) respectively. Recurrent ratio of T1a, T1b, T2 were 13.24%, 18.92%, 23.08% (P > 0.05) respectively. The recurrent rate was 33.33% of tumors offended the anterior commissure, versus 5.43% with no involvement of anterior commissure (P < 0.01). The recurrent rate was 59.09% of tumors offended the thyroarytenoid muscle, versus 5.36% with no involvement of thyroarytenoid muscle (P < 0.01). Unvaried and multivariate analysis indicated that the involvement of anterior commissure and the involvement of thyroarytenoid muscle were the factors of recurrence. CONCLUSION Recurrence of early glottic carcinoma after carbon dioxide laser treatment is effected by the involvement of anterior commissure and the involvement of thyroarytenoid muscle. Resection can be performed conservatively according to evaluation of macroscopic tumour extension.

Objective To evaluate the safety and efficacy of Centurion Vision System for subhixated cataract surgery.Methods Clinical data of 15 eyes with lens subluxation treated with Centurion Vision System were retrospectively reviewed.Ocular variables including visual acuity,intraocular pressure,corneal endothelial cell counts (CEC),central foveal retinal thickness (CFRT),intraocular lens (IOL) position,as well as intraoperative and postoperative complications were observed.Results The best corrected visual acuity (BCVA) was 0.6 or better in 10 eyes (66.7％) 3 months after surgery,while the BCVA of the other 5 eyes was between 0.2 and 0.6 mainly due to pre-existing macular degeneration caused by high myopia or trauma.CEC and CFRT values demonstrated a statistically significant difference between the preoperative and all postoperative follow-ups (all P ＜ 0.05).Three months after surgery,no serious surgeryrelated complications,such as retinal detachment,IOL dislocation,suprachoroidal hemorrhage,macular edema,were observed.Conclusion Centurion Vision System can facilitate phacoemulsification in eyes with subluxated lenses,and this technique is safe and effective due to providing excellent outcomes and avoiding vitreoretinal complications.

BACKGROUND: The study on the mechanism of force conduction of Ilizarov bone external fixator is of great significance for clinical orthodontics of the knee varus, the knee valgus and the tibial fracture. OBJECTIVE: To explore the force conduction mechanism of Ilizarov bone external fixator and the force changes of each orthopedic force in the process of tibia correction, and to objectively evaluate the overall use effect of the external fixator. METHODS: According to the structure of the external fixator, the coordinate transformation matrix relations were established, and the mathematical transformation relationship between the holding force and the pulling tension was obtained. A special laboratory bench was set. The experiment of tibia correction was conducted. The load on the external fixator and the variation of the orthotic force were measured. The theoretical value of the tension at the broken bone is calculated and compared with the actual value of the tension measured by the six-dimensional force sensor. The curve of efficiency of force transmission during correction was obtained. RESULTS AND CONCLUSION: (1) During the correction, the structure of the Ilizarov bone external fixator resulted in the interaction and restriction of its adjustment rod and support rod. When one adjustment force increased, the other adjustment force would decrease. (2) The efficiency of force transmission was increased greatly in the early stage, and then stabilized at about 50%. The experimental results could evaluate the overall correction effect of the external fixator. (3) Theoretical calculation and experiment of the tension at the broken bone due to the loss during the force transmission process were different in the result curves, but from the experimental results, it could be indicated that the overall force change trend of the adjustment force, supporting force, the theoretical value of the tension and the actual value of the tension was basically the same, indicating the validity of the theoretical calculations and experimental results. The evaluation results can provide a reference for the optimal design of Ilizarov’s external fixation architecture and the precise control of tibial orthopedic surgery.

ObjectiveTo investigate the relationship between levels of inflammatory cytokines, Ureaplasma infection in midtrimester amniotic fluid and spontaneous preterm delivery.MethodsFrom April 2009 to March 2012, a total of 1 865 pregnant women who underwent amniocentesis in midtrimester with known pregnant outcomes in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, among whom 43 cases who delivered spontaneously before 37 weeks, were classified as preterm group, and the control group consisted of 373 normal term delivery women selected from the other 1 785 cases who term delivered during the same period. Cytokines, including interleukin (IL)-10, IL-1β, IL-6, monocyte chemotactic protein-1 (MCP-1) and tumor necrosis factor-α (TNF-α) in amniotic fluid, were measured by MILLIPLEX MAP Human Cytokine/Chemokine Magnetic Bead Panel and analysis system for liquid phase chips.Ureaplasma DNA was detected by polymerase chain reaction. Sum-rank test was used to compare the difference of cytokines between the two groups and receiver-operating characteristic curve and Logistic analysis were used to analyze the value of cytokines to predict spontaneous preterm delivery.ResultsThe median maternal age in preterm group was higher than in the control group [34(24-49) vs 29(20-47) years] (Z=-3.107,P=0.002), but there was no significant difference in levels of the five cytokines among women with different age in control group(20-24, 25-29, 30-34 and≥35 years old) (allP>0.05). The levels of IL-1β and IL-6 were not significantly different between two groups (allP>0.05), but levels of IL-10, MCP-1 and TNF-α in the preterm group were much higher than in the control group [11.22(4.79-468.73) vs 7.87(0.93-26.62), 1 358.86(553.16-7 635.81) vs 1 137.98 (311.80-5 196.33), 9.78(5.72-106.51) vs 8.37(2.56-30.20) pg/ml, respectively;Z were-4.333,-2.820 and-3.390, allP<0.01]. The areas under receiver-operating characteristic curve of IL-10, MCP-1 and TNF-αwere 0.70, 0.63 and 0.66. The appropriate cut-off level of IL-10 in amniotic fluid for prediction of preterm birth was 9.06 ng/ml, with a sensitivity of 74.4% and a specificity of 57.6%, and the latter increased to 100.0% when combined with IL-10, MCP-1 and TNF-α, but the sensitivity declined to 16.3%.Ureaplasma was identified in only two preterm cases and none in the controls. However, the levels of the five cytokines in the two infected cases in preterm group were 2.12–43.00 times of the rest cases in the same group, and 2.26–60.00 times of the controls.ConclusionsAlthough IL-10, MCP-1 and TNF-α levels in midtrimester amniotic fluid are increased, it is not able to predict spontaneous preterm birth neither independently nor combined together. Ureaplasma infection rate in amnion cavity is low, but may related to parts of spontaneous preterm delivery.

Objective To study vascular anatomy between the pancreatic head and duodenum,providing anatomy basis for performing surgery of pancreatic head,duodenum and distal common bile duct in surgical practice. Methods Anatomy study was performed in 30 formaldehyde fixed and 10 fresh bodies in reference to blood supply to duodenum,the distal common bile and Vater ampulla. Results The anterior and posterior pancreaticoduodenal arterial arcade gives off branches to descending and horizontal portion of the duodenum. The posterior superior pancreaticoduodenal artery goes to distal common bile duct. The papilla artery arising from the posterior superior pancreaticoduodenal artery goes to Vater ampulla. Conclusions The pancreaticoduodenal anterior and posterior arterial arcades are main arteries that give off branches to the descending and horizontal portion of the duodenum,distal common bile duct and the Vater ampulla,hence should be carefully protected in duodenum-preserving resection of the pancreatic head.

Objective To investigate whether amniocentesis may increase the risk for mother-tochild transmission of hepatitis B virus (HBV).Methods Totally 40 children born to HBV-infected mothers who had amniocentesis performed in Nanjing Drum Tower Hospital, Nanjing University Medical School from January 2010 to December 2013, were followed up and screened for HBV markers.Amniotic fluid samples were collected and stored at-80 ℃ were tested for HBV markers.Among the 40 carrier mothers, three (7.5％) were hepatitis B e antigen (HBeAg)-positive.Relevant data such as antiviral history, administration of hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) in infants were collected.Chi-square test or Fisher's exact test was used for statistical analysis.Results The mothers were 21-41 years old, with a mean age of (31.5±5.5) years at the time of amniocentesis and mean gestational age of (21.2± 1.6) weeks (18.4-24.9 weeks).Indications for amniocentesis were mainly abnormal maternal serum alpha-fetoprotein levels (65.0％, 26/40)and maternal age over 35 years (10.0％, 4/40).None of the mothers received antiviral therapy and 14 (35.0％)underwent transplacental amniocentesis.Among 28 cases who had a store of amniotic fluid sample and were followed-up, one (7.1％) was positive for both hepatitis B surface antigen (HBsAg) and HBV DNA, and another was positive for HBsAg only.The average age of 40 children at follow-up was (2.0± 1.0) years (seven months to four years old), among which 23 were boys and 17 were girls.All of them received hepatitis B vaccine and HBIG.Positive rate of HBsAg and HBV DNA in HBeAg(+) mothers are higher than those in HBeAg(-) mothers [4.7％(2/43) vs 3/5, x2=14.705;0/43 vs 2/5, x2=17.948;both P ＜ 0.05].Thirty-seven children born to HBsAg(+)/HBeAg(-) mothers were negative for both HBsAg and hepatitis B core antibody (anti-HBc), and the other three born to HBsAg(+)/HBeAg(+) mothers were also negative for HBsAg and anti-HBc.Additionally, the positive rate of hepatitis B surface antibody in children was 90.0％ (36/40).Conclusions For those HBsAg(+)/HBeAg(-) mothers, amniocentesis does not elevate the risk for mother-to-child transmission of HBV, even performed transplacentally.However, further studies are needed for HBeAg-positive mothers.HBsAg or HBV DNA positive in amniotic fluid should be diagnosed as intrauterine infection of HBV.

Aim To investigate the sedative and hyp-notic effects of a novel compound H057 . Methods The sedative activity of H057 was investigated by re-cording the spontaneous locomotor activity in mice. The hypnotic property was evaluated by the latency and duration of loss of righting reflex( LORR) in mice and effect of H057 on the sleep onset in subthreshold dos-age of sodium pentobarbital treated mice. The extracel-lular levels of GABA and monoamine neurotransmitters in in cerebral cortex were measured by microdialysis in vivo. Results The spontaneous locomotor activity was decreased by 25% and 66% in H057 ( 5 , 25 mg · kg-1 ,i. p. ) treated mice, respectively. H057 ( 3, 5 mg·kg-1 ,i. p. ) increased the sleep onset to 62. 5%and 87. 5% in subthreshold dosage of sodium pentobar-bital(25 mg·kg-1,i. p. ) treated mice. H057(≥60 mg· kg-1 , i. p. ) could completely induce LORR in mice. The latency of LORR at dose of 60 mg · kg-1 was (24 ± 11) min and the duration of LORR was (96 ± 15 ) min. In vivo mircodialysis revealed that H057 (25 mg·kg-1 , i. p. ) could significantly increase the GABA level by 26% and decrease the 5-HT and NE levels by 50% and 38% in cerebral cortex in mice. Conclusion H057 has potent sedative and hypnotic effects, which may be closely related to the increased content of GABA and the decreased contents of 5-HT and NE in the extracellular fluid in cerebral cortex.
