Objective Investigation and analysis of intelligence and psychomotor function in children born after implementingt universal salt iodization(USI). Methods Historical serious illness areas of water iodine below 10μg/L were selected as study sites, water iodine in 50 - 100 μg/L in the historical non-endemic areas were as control points in Henan, 2008. Cluster sampling was used to select children aged 6 - 15 years as observing subjects,IQ were measured with CRT- Man Test(CRT-C2). A "Tianjin Medical psychomotor test battery" (JPB) was carry out to test psychomotor function. Results In IDD regions 230 children were surveyed post-USI and 1284 children preUSI. The IQs post and pre USI were 99.3 and 99.9, respectively, and the proportion of IQ ≤69 were 2.17%(6/230) and 2.80%(36/1284), respectively. In non-IDD regions 650 children were surveyed post-USI and 2079children pre-USI. The IQs post and pre USI were 95.3 and 93.8, respectively, and the proportion of IQ ≤ 69 were 2.31%(15/650) and 3.37%(70/2079), respectively. In IDD regions, the abnormal rate of T scores and damage index post USI were 3.6%(2/56), 5.3%(3/56), respectively, significantly lower than pre USI [18.1%(29/160),18.1%(29/160), x2 = 7.54, 6.86, all P ＜ 0.01]. Conclusions USI could increase the IQs of children and decrease the positive rate of JPB, and significantly improve the quality of whole nation and persistently eliminating IDD.

AIM:To establish a HPLC method for determining contents of tetrahydropalmatine and pepper alkali in Zhitong Capsule(Rhizoma Corydalis,Fructus Piperis,Radix Paeoniae alba,etc.)to control its quality.METHODS:The samples were extracted in water by ultrasonic wave,and then extracted by aether to refine after being acidized by 1 mol/mL HCl.Following that the pH of water solution was adjusted to 9.0-10.0 by NH_3?H_2O,and then extracted by aether again.After that,the aether solution was collected to evaporation to dryness and metered by methanol.The sample solution was determined by high performance liquid chromatography on a Hypersil ODS 2 C_ 18 column(4.6 mm?250 mm,5 ?m)with mobile phase composed methanol-0.1% phosphoric acid water solution(the pH was adjusted to 6.0 by triethylamine)(55∶45).The flow rate was 1.0 mL/min,the column temperature was at 30 ℃ and the signal from 0 to 14.5 minutes were acquired at 280 nm,and that from 14.5 to 22 minutes were detected at 328 nm.RESULTS:The resolution of tetrahydropalmatine and pepper alkali was good,with no miscellaneous peak.The linear range was at 0.196-1.96 ?g(r=0.999 6)for tetrahydropalmatine,0.03-0.3 ?g(r=0.999 7)for pepper alkali.The average rate of recovery of tetrahydropalmatine was 97.74%(RSD= 0.42%,n=6),and that of pepper alkali was 104.51%(RSD=2.01%,n=6).CONCLUSION:The method is simple,reliable,accurate and can be applied to the quality control of the preparation.

BACKGROUND:Currently, one of common methods is discectomy, nerve root decompression and fusion rigid fixation from the midline approach for disc herniation which is inefficient by conservative treatments. Thus, it is causing degeneration and limiting lumbar physiological activity of adjacent segments. The treatment of non-fusion lumbar disc herniation with the traditional posterior midline incision approach has some disadvantages such as big incision, wide peeling, and back muscle denervation.
OBJECTIVE:To observe therapeutic effects of dynamic stabilization system through Wiltse approach on lumbar disc herniation, and to compare the outcomes with traditional posterior approach.
METHODA total of 46 patients, who had undergone discectomy and internal fixation using dynamic stabilization systems for lumbar disc herniation at the Renmin Hospital of Wuhan University from January 2011 to January 2013, were enrol ed in this study. The operation was performed through the traditional posterior approach in 25 patients and Wiltse approach in 21 patients.
RESULTS AND CONCLUSION:Al 46 patients were fol owed up for 7 to 31 months (averagely, 13.8±2.4 months). The length of incision, intraoperative blood loss, and postoperative drainage amount were less in the Wiltse approach group than in the traditional posterior approach group (P<0.05). No significant difference in visual analog scale scores and operative time was detected between the two groups at 1 week and 6 months after fixation (P>0.05). Radiographs revealed that the position of implants was good in al patients, no loosing or breakage. These data verified that the early effect of dynamic stabilization system through Wiltse approach for lumbar disc herniation is similar to that of traditional posterior approach.

Objective:To study the effect of portal vein occlusion on intestinal mucosal barrier in rats and the protection of ulinastatin to the injury,to present the experimental data for the clinical surgery.Methods:70 Sprague-Dawley rats were randomly divided into controlled group (n=10),operation group (n=30) and operation+medication group (n=30).The portal vein were occlused 40 min in the operation groups and operation+medication groups.2ml blood from portal vein,lymph nodes around appendix,1cm small intestine wall were taken for endotoxin levels,bacterial translocation and pathiology examinations in the all rats 280 mins after operation.The mocusal barrier and microscopic structure of intestine were observed.Results:Compared between the control group and the operation group,endotoxin levels,bacterial translocation rates rise greatly and gut structure change obviously in the latter.Compared between the operation group and operation+medication group,the former changes is also obvious.Conclusion:The occlusion of portal vein can leads the decrease of intestine mocusal barrier and the increase of its permeability.Ulinastatin has a good protective effect on the damages above.

Objective To introduce the processes of vascularized parathyroid gland reservation and parathyroid autotransplantation applied in thyroidectomy. Methods In 46 cases who underwent total/near total thyroidectomy, in situ vascularized parathyroid gland reservation was performed in 24 cases,isolated parathyroid autotransplantation was performed in 5 cases, in situ vascularized parathyroid gland reservation of 1～2 parathyroid glands combined with immediately transplantation of the remaining isolated parathyroid glands were performed in 17 cases. Results Five cases suffered from transient hypocalcaemia, including 2 cases of vascularized parathyroid gland reservation and 3 cases of vascularized parathyroid gland reservation in 1～2 parathyroid glands combined with immediately transplantation of other parathyroid glands. Two cases who received parathyroid autotransplantation suffered from hypocalcaemia and received conservative treatment with activated vitamin D3 and caleium for 4 weeks or 8 weeks. Permanent hypoparathyroidism occurred in 1 case of 46 cases which undergone the total/near total thyroidectomy(2.2%). Conclusion Application of vascularized parathyroid gland reservation and parathyroid autotransplantation in total/near total thyroidectomy could reduce the incidence rate of post-operative hypoparathyroidism.

Objective To investigate the mechanism of neural protection of mouse nerve growth factor combined with sub-hypothermia in the treatment of patients with severe traumatic brain injury. Methods 90 cases of severe traumatic brain injury were randomly divided into study group and control group with 45 cases of each group, the control group were given routine treatment; the study group were given on the basis of routine treatment of mouse nerve growth factor combined with sub-hypothermia treatment, with 2 weeks treatment, the clinical indicators and corresponding nerve injury, inflammation, oxidative stress indexes, clinical effect and complications were compared after 2 weeks treatment. Results Compared with before treatment or control group, scores of Glasgow coma scale (GCS) and Glasgow outcome scale (GOS) and montreal cognitive assessment (MoCA) in study group after the treatment increased, National Institute of Health stroke scale (NIHSS) score decreased(P<0.05), neuronspecific enolase (NSE), myelin basic protein (MBP) and S100 beta levels decreased(P<0.05), the serum tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6), IL-10 levels decreased (P<0.05), the malondialdehyde (MDA) decreased, the glutathione peroxidase (GPx) and oxidation resistance (AOA) levels increased (P<0.05). The control group efficiency was 73.33%, the study group efficiency was 91.11%, there was significant difference (P<0.05). All patients were followed up, no case off, there was no significant difference in adverse drug reaction rate between two groups. Conclusion Mouse nerve growth factor and sub-hypothermia has the significant neural protection for patients with severe traumatic brain injury, and its mechanism may be related to reduce nerve injury indicators and improve inflammatory factor and oxidative stress response.

BACKGROUND:Tantalum rod implant technology is a new method of early osteonecrosis treatment. Current research on stress distribution before and after tantalum rod implant in different sizes of femoral head necrosis area is few. OBJECTIVE:To analyze the stress distribution before and after tantalum rod implantation in different sizes of necrotic femoral head area using three-dimensional finite element method. METHODS:Three-dimensional finite element models of normal femoral head and necrotic femoral head of 15, 20 and 30 mm diameterwere constructed. Eight measuring points were chosen on two tiers of each necrotic model to detect the stress distribution and its alteration before and after tantalum rod implantation. RESULTS AND CONCLUSION:(1) Stress concentration werefound on every necrotic femoral head, most pronounced on the one with 30 mm lesion. (2) Tantalum implant appeared to reduce the stress concentration generaly. Comparison of the peak points of these models indicated most significant benefit in 15 mm lesion, next in 30 mm lesion, last in 20 mm lesion. (3) Results indicate that larger lesion entails more concentrated stress distribution and more likely to colapse. Tantalum rod implantation can delay the development of necrosis of the femoral head, andismost effective in smal lesion.
