The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Purpose To compare the pathological differences between cervical high-grade intraepithelial lesions (CHGIL) positive resection surgical margin after cold knife conization and total hysterectomy,and to explore how to take further clinical treatment measures.Methods The pathologic results of 74 patients with CHGIL positive surgical margin after cold knife conization and hysterectomy were analyzed retrospectively.Results There was a correlation between positive cervical incision margin and residual uterine lesion (P ＜ 0.01).Age,menopause status,gland involvement did not related to residual uterine lesions(P ＞ 0.05).There was significant correlation between the lesion-related quadrant and the residual rate of uterine lesion (P ＜ 0.01).Conclusion Cold knife conization and hysterectomy are safe and effective treatments for CHGIL.However,for the positive resection surgical margin after cold knife conization cases,hysterectomy should be carefully chosen and may choose conservative treatment or re-cone cutting.

Objective To evaluate the efifcacy and safety of hemostatics of injected gelatin matrix (HIGM) under the guidance of contrast-enhanced ultrasound (CEUS) for treating splenic trauma in canine model. Methods A total of 24 commercial hybrid dogs underwent celiotomy with creation of uniformly blunt splenic trauma lesion of 4.0 cm×4.0 cm×2.5 cm (length, width and depth, respectively) by hemostatic clamp. Subjects were prospectively randomized into two groups. The treatment group was treated with HIGM under the guidance of CEUS and the positive control group received thrombin solution. Conventional ultrasound and CEUS were performed to record the ascites and the splenic lesion areas at 1st, 3rd, 7th, 14th and 21st day. The ifne needle biopsy and splenectomy were performed for histopathologic examination. The weight, free intraperitoneal lfuid and injury site were compared with t test between HIGM and postive group. Results All animals in two groups survived. All dogs stopped hemorrhage after injection of HIGM under CEUS guidance. The area of injury site was (12.91±0.89) cm2, (4.45±0.75) cm2 and (1.38±0.23) cm2 at 1st, 3rd and 7th day and splenic lesions were not found at 14th and 21st day in all dogs (n=12) of HIGM group. The splenic lesion was (16.74±0.91) cm2, (11.26±0.99) cm2, (8.02±0.82) cm2 and (1.58±0.36) cm2 in the postive group at 1st, 3rd, 7th and 14th day and splenic lesions were not found at 21st day in all dogs (n=12). At 7th and 14th day post-injection, lesion areas were statistically significant between two groups (t=27.162, P=0.008;t=15.129, P=0.001). Free intraperitoneal lfuid was (0.91±0.05) cm at 1st day detected by conventional ultrasound and free intraperitoneal fluid was not found at 3rd, 7th, 14th and 21st day in all dogs (n=12) of HIGM group. The free intraperitoneal fluid in thepositive group was (1.96±0.17) cm, (1.30±0.11) cm and (0.81±0.12) cm at 1st, 3rd and 7th day and free intraperitoneal lfuid was not found at 14th and 21st day in all dogs (n=12). At 1st, 3rd and 7th day post-injection, free intraperatitoneal lfuid was statistically significant between two groups (t=20.934, P=0.003; t=41.310, P=0.000; t=22.520, P=0.000). Histopathological examination showed that there was no foreign body and foreign body granuloma and the structure of red pulp was recovered at 7th, 14th and 21st day. Gross anatomy showed that the splenic injury site was recovered completely without complications. Conclusion This study explored the value of HIGM for splenic trauma and provided a preliminary experimental evidence for clinical treatment.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.

The computer-assisted surgery system is a complex system. All of the errors can be attributed to the loss of correspondence between the world coordinate system in the operation room and the virtual world coordinate system obtained from the multi-model medical images. The system's accuracy is composed of the accuracy of the localizer and that of registration. In order to improve the system accuracy, we analyse most of the possible error sources. The accuracy of the localizer affects deeply the registration between the intra-operation and pre-operation data. The localizer is the most basic and important part for a computer-assisted surgery system. We give a comprehensive possible error source at the end of the paper.
