The effects of minimally invasive surgery on the blood-brain barrier (BBB) of 30 patients with cerebral hemorrhage were investigated. Difference of the BBB index and serum MBP concentration were assessed in 15 cases of conservative treatment group and 15 cases of minimally invasive surgery group. The BBB index in minimally invasive surgery group was significantly lower than in conservative treatment group (P<0.05), and the BBB index in the two treatment groups was significantly higher than in control group (P<0.01). Serum MBP concentration in minimally invasive surgery group was significantly lower than in conservative treatment group (P<0.05), and that in the two treatment groups was significantly higher than in control group (P<0.01). It was suggested the permeability of BBB in patients with cerebral hemorrhage was increased, and BBB index and serum MBP concentration in patients with cerebral hemorrhage were increased. Minimally invasive surgery can reduce the lesion of cytotoxicity to BBB and cerebral edema.

In this study nine cases of thallium poisoning in a series of homicidal poisoning were analyzed in order to provide more information concerning thallium poisoning. It was found that the most common clinical feature of thallium poisoning was peripheral neuropathy and paraesthesia was more common than amyasthenia. Understanding of these clinical characteristics of thallium poisoning was helpful to early identification and differential diagnosis. Since the early administration of Prussian Blue, as a specific antidote for thallium poisoning, can substantially improve the prognosis, it is of great importance to establish a correct and early diagnosis.

Objective To compare the value of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography in the diagnosis of breast cancer. Methods A total of 32 patients with suspected breast cancer were enrolled into this study. All patients underwent (~99m) Tc-octreotide scintigraphy and planar X-ray mammography. The diagnostic efficiency of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography were compared based on the post-surgery pathology. Results The sensitivity of (~99m) Tc-octreotide scintigraphy and planar X-ray mammography in the diagnosis of breast cancer was 91.67% and 66.67%, the specificity was 100% and 37.50%, the accuracy was 93.75% and 59.38%, respectively. Combining (~99m) Tc-octreotide scintigraphy with planar X-ray mammography, the sensitivity, specificity, accuracy, positive predicting values and negative predicting values for breast cancer was 95.83%, 100%, 96.88%, 82.14% and 47.06%, respectively. Conclusion The diagnostic efficiency of (~99m) Tc-octreotide scintigraphy for breast cancer is superior to planar X-ray mammography. (~99m) Tc-octreotide scintigraphy combined with planar X-ray mammography, the diagnostic efficiency for breast cancer will be further improved.

Objective To evaluate the role of 131I SPECT/CT in post-surgical re-staging and recurrence risk stratification in patients with DTC and its impact on subsequent treatment strategy.Methods 131I-WBS and 131I SPECT/CT were performed at the same time 5 to 7 d after 131I treatment in 118 patients (33 males,85 females,average age 45 years) with DTC.Difference in the localization and qualitative diagnosis of 131I uptake lesions between 131I-WBS and 131I SPECT/CT were compared.Value of 131I SPECT/CT in the diagnosis of TNM staging,risk stratification and impact on the treatment strategy was evaluated.Paired χ2 test was used for data analysis.Results A total of 509 foci with 131I uptake were detected.131I-WBS found 449 foci with 131I uptake,354 of which (78.84%) were correctly diagnosed.131I SPECT/CT found 509 foci with 131I uptake,and 504(99.02%) were correctly diagnosed.The difference was statistically significant (χ2=21.51,P<0.01).131I-WBS changed the clinical staging in 13 cases with diagnostic accuracy of 5/13.131I SPECT/CT changed the clinical staging in 19 cases and with diagnostic accuracy of 19/19 (χ2=74.41,P<0.01).131I-WBS changed the risk stratification of 13 patients after operation and the accuracy was 5/13,the corresponding data were 22 and 100%(22/22) for 131I SPECT/CT (χ2=74.41,P<0.01).The treatment strategy was changed in 50 patients with 131I SPECT/CT.Conclusions Compared with 131I-WBS,131I SPECT/CT could provide more accurate positioning and qualitative information for 131I treatment and is more accurate in re-staging and risk stratification.

Objective To establish gastric bypass surgery model with SD rat and analyze the influence factors and preventive measures so as to accumulate experience and skills for further developing gastric bypass surgery model on diabetic rat( GK rat) . Methods Gastric by-pass surgery was operated on 30 SD rats. Summarized modeling experience and analyzed various factors affecting modeling success. Results 17 rats weresuccessfully survived after surgery and 13 failed, with the mortality rate 43. 3%. Three rats died during operation, including two for anesthesia and one for heart failure;one died due to anastomotic bleeding two hours after surgery. Eight died in the third day after surgery, including two for infection, two for intestinal necrosis, four for anastomotic stenosis or obstruction. One died because of anastomotic leakage caused by mistaking and satiety the fifth day after surgery. There were no other complications such as wound dehiscence occurred in this group . Conclusion Establishing models of gastric bypass surgery with SD rats which is regarded as pre-experiment of building models of gas-tric bypass surgery with GK rats is economical and feasible. Anesthesia and perioperative management, surgical techniques and infection pre-vention and control are the main factors affecting modeling. The survival rate of rat model could be increased if related factors well controlled.

Seventy eight children with Henoch-Schonlein syndrome (HSP) admitted in our hospital from October 2013 to April 2015 were enrolled in this study,and 30 healthy children were also enrolled as controls.The serum S-100 protein levels were measured with enzyme-linked immunosorbent assay (ELISA)in two groups;and electroencephalogram (EEG) examination was performed in HSP patients.The serum S-100 protein level of HSP group (0.206 ± 0.101) μg/L was significantly higher than that in the normal control group [(0.060 ±0.042) μg/L,P < 0.001];and the serum S-100 protein levels in patients with kidney type (0.284 ±0.099) μg/L and mixed type [(0.284 ±0.043) μg/L,P <0.01] were higher than those in patients with skin type (0.151 ±0.098) μg/L,gastrointestinal type (0.138 ±0.036) μg/L and joint type [(0.117 ± 0.065) μg/L,P < 0.001].Abnormal EEG findings were detected in 52 cases (66.7%),however,no clinical manifestations of nervous system were found in those patients.Serum S-100 protein levels were higher in patients with abnormal EEG than those with normal EEG [(0.223 ± 0.099) μg/L vs.(0.173 ± 0.096) μg/L,P < 0.05].The results suggest that the serum S-100 protein is associated with HSP disease severity,and children with HSP may have subclinical neurological damage.
