The segmental and regional projections of the sciatic, tibial and common peroneal nerves to the substantia gelatinosa of spinal cord in rats were studied with the acid phosphatase method. Experiments were carried on 42 rats. Under chloral hydrate anesthesia, sciatic, tibial and common peroneal nerves were severed respecively. Then, after a survival time of 5～12 days, the lumbosacral segments of the spinal cord were removed and sectioned. The frozen sections were incubated with the modified Gomori's method.The projections of the sciatic and tibial nerves to the substantia gelatinosa (SG)were found in L_2～S_1, while these of the common peroneal nerve in L_(2～6).The projections of the sciatic nerve were found in the most medial, the intermediate and the most lateral parts of SG in the segments L_(2～3), and in entire SG in the segments L_4～S_1.The projections of the tibial nerve were shown in the most medial and the intermediate parts of SG in the segments L_(2～5), and in the medial parts of SG at L_6～S_1.The projections of the common peroneal nerve were found in the intermediate parts of SG in all segments L_(2～6).The above study has provided anatomical data for probing into the mechanism of somatosplanchnic interrelations and the principle governing acupuncture anesthesia.

Objective To study the efficacy of fixation with knee arthroscopy as adjuvant therapy for lateral tibial plateau fracture. Methods 72 cases with lateral tibial plateau fracture of our hospital from September 2011 to September 2014 were divided into experimental group (36 cases) and control group (36 cases), according to different operation method, the experimental group using arthroscopic, while the control group using traditional incision surgery. Then the incision length, operative time, hospital stay, wound healing, bone healing time were compared. Complications, knee function and reduction of the fracture were compared. Results The incision length of experimental group was significantly lower than the control group, the difference was statistically significant (P <0.05). Operative time, hospital stay, wound healing time, the bone healing time were significantly lower than the control group, the differences were statistically significant (P < 0.05). Delay healing, joint stiffness and traumatic arthritis were significantly lower than the control group, the differences were statistically significant (P < 0.05). RASMUSSEN function score and radiographic scores in the experimental group were significantly higher than the control group, the differences were statistically significant (P < 0.05). Conclusion Fixation with knee arthroscopy as adjuvant therapy for lateral tibial plateau fracture has advantages of smaller incision, shorter operative time and hospital stay and healing time, lower complication rate while better reduction of the fracture and function than conventional methods.

Objective To investigate the relationship between intrauterine growth retardation (IUGR) and en docrine parameters so as to assess the effects of the main endocrine factors on IUGR. The concentrations of growth hormone (GH), insulin, T3, T4 and TSH were measured in umbilical cord blood, amniotic fluid and maternal serum. Methods The samples were collected from 23 pregnant women who were diagnosed as the full term IUGR, 42 normal full term pregnant women with normal infants' weight were taken as control. Growth hormone and insulin were mea sured by radioimmunoassay. T3, T4 and TSH were investigated by micro-radioimmunoassay. Results The concentra tions of growth hormone, insulin and T4 in umbilical cord blood were lower in IUGR than that in control group(GH 4. 63μg/L vs 7.01μg/L, insulin 10. 68μIU/ml vs 31.44μIU/ml, T4 87. 39nmol/L vs 138. 10nmol/L. P ＜0. 05, 0. 05 and 0. 05, respectively). The TSH concentration in umbilical cord blood was higher in IUGR than in control group (10. 84μmIU/L vs 5. 75μmIU/L, P ＜0. 01). The concentration of growth hormone in maternal serum and the concen tration of insulin in amniotic fluid were also lower in IUGR group than in control group(GH 1.77μg/L vs 2.74μg/L, P ＜0. 01, insulin 5. 84μIU/mi vs 15. 64μIU/ml, P ＜0. 01). Conclusion This study confirms that full term neonates with IUGR are abnormal in endocrine factors. The inadequacy of growth hormone may be one of the causes of IUGR. The relative scarcity of growth hormone and insulin seems to be a factor to compromise the fetus' metabolism. Be sides, the early hypothyrosis of infants with IUGR might protect them from unfavorable environment in the uterine.

Objective To investigate the efficacy of transcutaneous injection of MIIGX3 artificial bone and methylprednisolone for recurrent bone cysts.Methods From January 2004 to March 2006,a total of 13 children with recurrent bone cysts received transcutaneous injection of methylprednisolone and MIIGX3 in our hospital.X-ray was employed to detect the degradation of MIIGX3 and formation of new bones.Results The operation time ranged from 30 to 95 minutes(mean 42 minutes).The patients were followed up for 1 to 3 years.None of them had recurrence of bone cysts during this period.The artificial bones were completely degraded and replaced by new bones in 1.5 years after the injection.Conclusions Transcutaneous injection of methylprednisolone and MIIGX3 is effective for recurrent bone cysts.Patients have shorter operation time and hospital stay after this treatment because the procedure is microinvasive.

Currently praziquantel is one of the major drugs used in treatment of schistosomiasis and other trematode infections.Recent experimental studies indicate that a new anthelmintic,tribendimidine,is used in the treatment of intestinal nematodes,also possesses effect against several species of trematodes including Clonorchis sinensis,Opisthorchis viverrini and Echinostoma caproni.Tribendimidine is even more effective against C.sinensis in rats that a single 300 mg/kg oral dose cures almost all of the animals treated,a lower cure dose than praziquantel(375-500 mg/kg).The anti-malarial drugs artemether and artesunate are not only effective in the prevention of schistosomiasis,but also effective against several species of trematodes,especially C.sinensis.The single oral dose of both drugs to cure or achieve high efficacy in infected rats is 75 mg/kg.This review summarized research progress on tribendimidine,artesunate,and artemether in experimental animals infected with C.sinensis and other species of trematodes.

Objective To study the characteristics and regularities of Chinese drugs preparations ADR in order to improve the rational drug use.Methods A total of 112 cases of TCM ADR reports collected in 2009～2011 which have been presented to the Guangzhou ADR Monitoring Center.Results Of the 112 cases,26 kinds of drugs were involved,quinquagenarian were the main crowd,intravenous infusion was the main route of administration,the main types of TCM ADR were lesions of skin and accessories.Conclusion Great importance should be attached to TCM ADR monitoring to promote rational drug use in the clinic.

Objective This investigation was launched to characterize the relationship between some popular sports and the meniscus injury as well as the impairment extent due to practice duration.Methods The overall 819 women aged 20-49 years from clinic service,hospital,community and gymnasium were selected to join the investigation.The participants practice yoga or any other popular sports including badminton,jogging,climbing hills for at least one hour per day.The subjects were diagnosed with meniscus injury by means of physical examination and MR imaging.All of the subjects were therefore divided into the case(273)and the control(546)pools.The nested case-control model was applied to assess the relative risk of the meniscus.The 181 yoga subjects had been further divided into three sub-groups of 3-6 months,6-12 months and over 12 months,and they were accordingly analyzed with the variables of the age,body mass index(BMI)and Lysholm score.Results The study showed that yoga was associated with higher risk(OR=1.621,P=0.008)of meniscus injury,but the other sports showed no statistically significant risk (badminton 0R=1.028,jogging OR=1.116,climbing hills OR=1.259).The trainees appeared to be statistically different between the groups of 3-6 months and over 12 months on the items of the Lysholm score(P=0.006)and BMI(P=0.003).Conclusion Yoga plays a risky role on the issue of meniscus injury comparing some other popular sports among young women.The yoga players who exercise longer got lower Lysholm scores and lighter weight.

Objective To investigate changes in serum level of glial fibrillary acidic protein (GFAP) in patients with Parkinson disease (PD) and its clinical significance. Methods Serum GFAP was determined with sandwich ELISA for 82 patients with PD and acute cerebral infarction (ACI), as well as healthy normal controls. Patients with PD were then divided into two sub-groups in terms of their course duration, one with less than five years and the other with more than or equal to five years. Effects of course duration and age of the patients on their serum GFAP were analyzed. Results Serum level of GFAP was significantly higher in patients with PD [(1.628±0.104) μg/L] and ACI [(1. 637±0. 063 )μg/L] than that in healthy normal controls [ (0. 025±0. 003)μg/L, t = 82. 7, 142. 2, all P <0. 05 ]. But, there was no significant difference in serum GFAP between patients with PD and ACI ( t =0. 214, P > 0. 05 ). Serum level of GFAP in PD patients had no significant correlation with their age. There was no significant difference in serum GFAP between two sub-groups of patients with PD (P > 0.05 ). Conclusions Serum level of GFAP increased significantly in PD patients, as compared to healthy normal controls, but it is not specific. Serum GFAP in patients with PD maintained at certain high level with progression of the disease, indicating effect of astrocytes may persistently exist during the disease course.
