Objective To understand the situation of iodine deficiency disorders of Cangzhou city, Hebei province, in order to provide the scientific basis for prevention and control of iodine deficiency disorders. Methods From 2007 to 2009, dynamic monitoring of iodine deficiency disorders was carried out in low iodized salt coverage places Hejian city and Xian county. Nine towns were randomly chosen in each county, 4 administrative villages were randomly selected in each town, 8 household salts were tested in each village. Every year, 1 - 3 copies of residents water samples were collected for determination of iodine; more than 100 students age 8 - 10 years old were checked the situation of goiter and urinary iodine, more than 40 students selected were measured iodine content of salt from their home; more than 50 women of childbearing age 18 - 40 years were tested of urinary iodine. Thyroid was examined with palpation; water iodine and urine iodine concentration were measured with arsenic-Ce catalytic spectrophotometry; salt iodine was detected by direct titration. Results From 2007 to 2009,median household salt iodine were 4.3,15.9,3.6,18.4,4.6,11.7 mg/kg in Hejian city and Xian county, respectively,iodized salt accounted for 34.03% (98/288), 78.82% (227/288), 29.86% (86/288), 84.72% (244/288), 37.15%(107/288),49.31% (142/288), respectively, the consuming rate of iodized salt were 27.08% (78/288),36.46%( 105/288 ), 28.13% (81/288 ), 49.31% ( 142/288 ), 37.15 % ( 107/288 ), 30.90% ( 89/288 ), respectively. Ten samples of drinking water were tested, water iodine were 5.5 - 34.4 μg/L. From 2007 to 2009, the goiter rate of students aged 8 - 10 years old was below 5%, the median of urinary iodine were 138.1,176.6,112.0 μg/L, ＜ 100 μg/L ratio were 31.6% ( 65/206 ), 25.0% ( 52/208 ) and 44.4% (91/205 ). The median of urinary iodine of child-bearing age women were 167.3,164.2,78.1 μg/L, ＜ 100 μg/L ratio were 28.7%(29/101 ), 19.2%(20/104) and 60.0%(60/100).Conclusions In areas with low coverage of iodized salt, iodine nutrition level are affected, the child-bearing age

OBJECTIVETo evaluate effects of different treatments on patients with osteoporotic vertebral fracture after percutaneous kyphoplasty in pain and function.

METHODSFrom March 2010 to March 2012,138 patients (165 vertebrae) with thoracic and lumbar vertebral osteoporotic fracture were randomly divided into three groups (control group, treatment group and comprehensive group), 46 cases in each group, and all patients were treated by PKP. Control group were treated with calcium and calcitriol after operation, treatment group added salmon calcitonin see calcimar based on control group, comprehensive group added incrementality waist musculi dorsi function exercise based on treatment group. VAS, ODI scores and BMD before operation, 3 d, 2 weeks, 1 month, 6 months and 12 months after operation were detected and compared.

RESULTSAll operation were performed successfully,38 cases (45 vertebrae) in control group, 36 cases (44 vertebrae) in treatment group and 40 cases (49 vertebrae) were obtained complete following up, there was no significant meaning in following time among three groups (P>0.05). Postoperative VAS and ODI scores at 3 d, 2 weeks and 1 month among three groups were lower than that of before operation (P<0.01). Compared with control group, postoperative VAS score at 3 d, 2 weeks and 1 month were decreasedin treatment group and comprehensive group, but there was no significant meaning in ODI scores (P>0.05). At 6 and 12 months after operation,there was no significant differences in VAS and ODI between control group and treatment group (P>0.05), while VAS score in comprehensive group decreased much than other two groups,decreased continuously (P<0.01). At 12 months after operation, BMD among three groups were increased more than preoperative,and BMD in comprehensive group was more obviously than that of in control and treatment group.

CONCLUSIONPKP, an effective method for the treatment of thoracic and lumbar vertebral osteoporotic fracture, could improve short-term clinical effects by adding calcitonin with calcium supplements and activated vitamin D. Waist musculi dorsi function exercise could improve long-term clinical effects of PKP and improve quality of life.

Objective To evaluate the CT and MRI characteristics of Primary Central Nervous System Lymphoma(PCNSL)in immunocompetent patients,and enhance its diagnosis level.Methods CT and MRI data of 20 patients with PCNSL confirmed by histo-pathology were analyzed retrospectively.MRI scans were performed with and without Gadolinium contrast.Two of them had contrast-enhanced CT scan;six had CT scan without contrast administration;1 had CT scan with both non-contrast and contrast enhancement.Re- suits Totally,38 lesions were found in all patients:14 lesions of them were single and 24 lesions were found in 6 patients.Generally,the lesions were located in the surface and/or midline of the brain.The signal features and density were similar to meningioma,and strongly enhancing after contrast administration.Thirty-six of the 38 lesions had spicular sign peripheral to the lesion.Conclusion Although the manifestations of the PCNSL are variety,there are still many characteristics in the medical imaging,especially in the locations,the signal features,and spicular sign in the edge of the lesions after contrast material injection.

Objective:To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition.Methods:The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital,Second Military Medical University.He was hit by heavy object during the Sichuan earthquake 6 days ago.Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis.The patient underwent cervical 3-7 laminectomy under general anesthesia.Results: After surgery,the muscle strength of lower limbs recovered to grade four from grade one;the muscle strength of upper limbs recovered to grade five from grade three.Sensory loss was found below the nipple level and totally recovered after operation.Conclusion:Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients.Under field condition where facilities are not readily available,decompression of spinal cord can be achieved by lamineetomy via posterior approach.The key to successful operation is correct diagnosis and skillful manipulation.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

OBJECTIVETo investigate the pathological diagnostic features and the differential diagnosis of radial sclerosing lesions of the breast.

METHODSMorphological observation and immunohistochemistry were applied to forty-four cases of radial sclerosing lesions of the breast.

RESULTSAll forty-four patients were females, the mean age was 40.3 years (range 17 to 54 years). In the 31 consultation cases, 13 were misdiagnosed as carcinoma. The lesions had a radiating outline, and a central scar area where squeezed or pressed irregular shaped tubules were frequently seen. Dilated tubules and proliferated ducts or lobules were seen radically arranged at the periphery accompanied sometimes with the apocrine glands or columnar cell metaplasia and hyperplasia. Aside, there were 14 cases displaying necroses and 8 cases showing atypical ductal hyperplasia. Immunostaining showed myoepithelial cells around the pseudo-infiltrating tubules, and the florid proliferating epithelial cells were positive for CK5/6.

CONCLUSIONSRadial sclerosing lesions of the breast possess characteristic histological features, and may be misdiagnosed as carcinoma. The lesions should be differentiated from ductal carcinoma in situ, lobular neoplasia, tubular carcinoma and invasive ductal carcinoma.

In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P. notoginseng, the effects of the different proportion of potassium chloride (KCl) and potassium sulfate (K2SO4) on the yield, quality of P. notoginseng were studied. The results showed that K fertilizer significantly improved the growth of P. notoginseng and increased the biomass per plant or per pot and the content of N, P, K and the content of saponin. In cases of conditions such as potassium, and the effects of K2SO4 on increasing the petiole length, leaf size, rhizome length, root length, and content and accumulation of Ginsenoside Rg1 were better than those of KCl. While compared with K2SO4, KCl was more conducive to augmenting height, root width, the biomass of shoot, rhizome, root and the content of Ginsenoside Rb1 and Rd. There was not remarkable difference in agronomic characters, biomass and the content of N, P, K among KCl, K2SO4 and the combination of KCl and K2SO4. However, the content of saponin of the treatment with combination of KCl and K2SO4 was significant higher than that of single KCl or K2SO4 treatments. K fertilizer significantly increased yield and the content of saponins. And P. notoginseng was not sensitive to chloridion. KCl increased the yield and the content of saponins of P. notoginseng as well as K2SO4, and the combination treatment was superior to single treatment. It is recommended that the KCl should be adopted in production, to reduce the cost of potash fertilizer.
