Objective To explore clinical characteristics of severe pre-eclampsia and eclampsia complicated with reversible posterior leukoencephalopathy syndrome(RPLS).Methods Clinical data of 31 cases of severe pre-eclampsia and eclampsia complicated with RPLS were studied retrospectively.ResulIs These 31 cases with RPLS accounted for 48% of those with eclampsia,.and all presented with hypertension,headache and disturbalice of vision,24 cases with seizure episodes,19 cases with nausea and vomiting and 13 with continuous dysphoria after seizure.Neuroradiologic findings showed edema predominantly in the bilateral posterior cerebral white matter,especially in occipital-parietal lobe,with low density lesions in CT and long T1 and T2 signals in brain MRI. Conclusions Severe pre-eclampsia and eclampsia tended to complicate with RPLS,presenting severe hypertension,headache,disturbance of vision and recurrent seizure as major clinical manifestations.

OBJECTIVE:To systematically review the efficacy and safety of reinforcing kidney and invigorating spleen princi-ple in the treatment of primary osteoporosis (POP) in middle and elderly aged patients,and provide evidence-based reference for clinic. METHODS:Retrieved from VIP,Wanfang Database,CJFD,Medline,PubMed,Elsevier,Springer,Web of Science and Ovid,randomized control trials (RCT) about reinforcing kidney and invigorating spleen principle (test group) versus other meth-ods(no reinforcing kidney and invigorating spleen principle,control group)in the treatment of POP were collected. Meta-analysis was performed by using Rev Man 5.3 software provided by Cochrane after data extraction and quality evaluation modified by Jadad scale. RESULTS:Totally 28 RCTs were enrolled,involving 2849 patients. Results of Meta-analysis showed,the total effective rate [OR=3.80,95%CI(2.76,5.23),P<0.001],BGP level [MD=2.23,95%CI(1.80,2.66),P<0.001],BMD level of femoral neck [MD=0.04,95%CI(0.00,0.08),P=0.05] and BMD level of lumbar spine [MD=0.07,95%CI(0.03,0.11),P=0.001] in test group were significantly higher than control group,ALP level [MD=-5.59,95%CI(-10.51,-0.66),P=0.03] and VAS score [MD=-1.38,95%CI(-1.87,-0.89),P<0.001] were significantly lower than control group,with statistical significance. There were no significant differences in U-Ca/Cr [MD=-0.07,95%CI(-0.17,0.02),P=0.12] and serum Ca2+ level [MD=0.16,95%CI (-0.07,0.39),P=0.17] in 2 groups. CONCLUSIONS:Reinforcing kidney and invigorating spleen principle can improve patients' osteogenesis during bone metabolism,reduce the activity of the osteoclastic process and relief patients'pain in the treatment of POP.

OBJECTIVETo observe the changes of proximal femoral geometry after femoral neck fracture treated with THA, analyze the existent of differences and their manifestation.

METHODSAll patients of femoral neck fracture (FNF) and osteonecrosis of femoral head (ONFH) were treated with THA by the same operating team from January to December of 2014, including 22 patients with FNF (11 males and 11 females,with age from 44 to 83 years old (means 66.18 ± 11.47) and 23 patients with ONFH (12 males and 11 females, with age from 19 to 68 years old (means 51.91 ± 11.76). After THA, height of femorals, offsets, osteotomy position and adjusting modes were measured and the statistic analysis was done.

RESULTSAfter THA, all patients were measured. Decreased femoral height, offsets and lower osteotomy positions were found in patients with FNF than those with ONFH, and 3 kinds of adjustments because of lower-positional osteotomy were found.

CONCLUSIONAfter THA, lower-positional osteotomy and decreased femoral offsets may occur on patients with FNF. The adjustments caused by lower-positional osteotomy may lead to negative results.

This study aims to save cost of sampling for estimating the area under the amlodipine plasma concentration versus time curve in 24 hours (AUC(0-24 h)). Limited sampling strategy (LSS) models was developed and validated by mutiple regression model within 4 or fewer amlodipine concentration values. Absolute prediction error (APE), root of mean square error (RMSE) and visual predict check were used as criterion. The results of Jackknife validation showed that fifteen (9.4%) of the 160 LSS based on regression analysis were not within an APE of 15% by using one concentration-time point. 156 (97.5%), 159 (99.4%) and 160 (100%) of the 160 LSS model were capable of predicting within an APE 15% by using 2, 3, 4 points, separately. Limited sampling strategies have been developed and validated for estimating AUC(0-24 h) of amlodipine. The present study indicated that the implemention of both 5 mg and 10 mg dosage could enable accurate predictions of AUC(0-24 h) by the same LSS model. This study shows that 12, 4, 24, 2 h after administration are key sampling time points. The combination of (12, 4), (12, 4, 24) or (12, 4, 24, 2 h) might be chosen as sampling hours for predicting AUC(0-24 h) in practical application according to requirement.

Objective To assess the relationship between serum vitamin D and autoimmune thyroid disease.Methods Subjects included total 520 persons receiving regular health examination,and serum calcium,phosphorus,parathyroid hormone (PTH),thyroid peroxidase autoantibody (TPOAb) and 25-dihydroxy vitamin Ds was measured.The incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μ g/L)was observed.The relationship between 25-dihydroxy vitamin D3 deficiency and autoimmune thyroid disease was analyzed.Results The serum 25-dihydroxy vitamin D3 of all the subjects was (24.47 ± 7.21) μ g/L,and the incidence of 25-dihydroxy vitamin D3 deficiency (≤30 μg/L) was 61.15％ (318/520),and the positive rate of TPOAb was 21.54％ (112/520).The proportion of TPOAb ＞ 50 kU/L or ＞ 100 kU/L in subjects with 25-dihydroxy vitamin D3≤30 μ g/L was higher than that in subjects with 25-dihydroxy vitamin D3 ＞ 30 μg/L [25.79％(82/318) vs.19.80％(40/202) and 9.43％(30/318) vs.4.46％(9/202)],and there was significant difference (P ＜ 0.05).The relationship between 25-dihydroxy vitamin D3 and TPOAb was assessed and showed significant inverse correlation (r =-0.13,P ＜0.05).Conclusions Vitamin D deficiency is very common in the population,and autoimmune thyroid disease is related with vitamin D deficiency,which may has impact on the body's immune regulation.Specific mechanism and whether vitamin D supplementation can intervene and treat autoimmune thyroid disease need further study.

[Summary] To determine how endocrinologists in China access and treat patients with Graves' orbitopathy (GO) and gain insight on how to make the management of this disease more uniform and standardized in the context that management of GO continues to be challenging.Based on the questionnaire used in the European survey on GO,a questionnaire in Chinese was drafted and circulated to the members of Chinese Society of Endocrinology (CSE).There were a total of 124 valid responders.The majority (94.4％) of the responders believe that a muhidisciplinary approaches for GO management is valuable.Over 80％ of the participants advocated the evaluation of exophthalmometry,vision,visual fields by perimetry,eye movements,fundoscopy,TSH receptor antibodies,thyroid function,and ultrasound.Steroids were preferred as the first-line therapy by 92.7％ of responders,among them,59.7％ choose intravenous route.The treatment strategy for GO with intravenous glucocorticoids therapy still remains debated.Antithyroid drugs were the most common choice (72.6％) for first-line therapy of thyrotoxicosis.Treatment options for GO were very similar among Chinese,Latin-American,and European responders,though radioactive iodine and surgical treatment were more often indicated in China.The appropriate treatment of the patient with GO is controversial even amongst thyroid specialists.Further training of clinicians,easier access of patients to specialist multidisciplinary centres,and the publication of practice guidelines may help improving the management of this condition in China.

OBJECTIVETo summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures.

METHODSFrom September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up.

RESULTSAll 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05).

CONCLUSIONPatients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

Objective To observe the change of capillary pericapillary cells in rats with myocardial infarction and the influence of supplementing qi and activating blood circulation herbs, and explore its mechanism of improving myocardial perfusion. Methods The rat model was established by ligaturing the left anterior descending coronary artery. On the base of ECG evaluation, successfully modeled rats were randomly divided into the model group, group treated with supplementing qi and activating blood circulation Chinese medicine (activating blood and supplementing qi group), group treated with Perindopril (Perindopril group), group treated with Tongxinluo Capsules (Tongxinluo group). The sham-operation group was taken as the control. There were totally 5 groups. The model group and the sham-operation group were treated with normal saline. The changes of myocardial capillary density (MCD) and number of pericapillary cells on the 7th, 28th day after medicinal administration were observed. Results On the 7th and 28th day, the MCD decreased significantly and the number of capillary pericapillary cells increased significantly in the model group compared with the sham-operation group (P<0.01). The MCD increased significantly in the activating blood and supplementing qi group, Perindopril group and Tongxinluo group compared with the model group (P<0.01). The number of pericapillary cells decreased significantly in the activating blood and supplementing qi group, Perindopril group and Tongxinluo group compared with the model group (P<0.01). Conclusion The supplementing qi and activating blood circulation herbs can improve regional myocardial blood supply by decreasing the number of pericytes and promoting regeneration of capillary.

Objective To probe into the optimization of scanning parameters of chest with low-dose spiral CT.Methods The phantom was scanned with different scanning parameters.The image quality obtained with the standard dose parameters and the low-dose technique were compared to evaluate the spatial resolution,low contrast resolution,noise level field uniformity and radiation dose,then the optimal scan parameters were defined.The scanning parameters were 120 kV,0.75 s,Pitch 1.0,FOV 360,RF3 reconstruction model(standard filter).Different thickness and tube electricity were used and the data were analyzed with the statistical method.Results There was significant difference about the data of the CTDI between the 160 mA conventional spiral CT and the low dose groups(30 mA,50 mA,70 mA,90 mA).There was no significant difference about the CTDI between 30 mA and 50 mA,and between 50 mA and 70 mA.There was obviously significant difference about the image noise on 1 mm slice and 10mA with other groups.The spatial resolution and low contrast resolution increased along with the increase of tube electricity,and 50mA was a inflexion of low contrast resolution.Conclusion 50mA and 5mm slice are the best scanning parameters in low-dose lung scanning and adapt to routine screening and early lung cancer screening.
