Ojective To evaluate the therapeutic effect of conformal radiotherapy on metastatic hepatic cancer. Methods 10 cases of metastatic hepatic cancer (1 to 5 metastatic focus respectively) were treated with stereotactic radiotherapy from Septermber 1997 to April 2000. The clinical target volume(CTV) of tumor ranged from 0.6cm 3 to 232cm 3 (the mean 41.9cm 3), peripheral irradiation doses of planning target volume (PTV) ranged from 3.96Gy to 7.00Gy(the mean 5.26Gy)each time, cential irradiation doses of PTV were 6.3Gy~10.88Gy (the mean 7.89Gy) each time, once a day for 5~8 times totally. Results No patient died during therapy. KPS of patients normal condition were 20~90(54?25.90) before treatment and 30~100 (74?23.90) after treatment. Effect of entity tumor were as follows completely relaxed (CR) in two cases, partly relaxed (PR) in four cases, no change (NC) in three cases, progressed (PD) in one case. During follow-up period tasting 2 to 28 months 90% of the tumors were controlled (no progressive disease). 60% fo the tumors decreased in size or disappeared. Conclusions Stereotactic radiotherapy has better therapeutic effects on cases of metastatic hepatic cancer.

Objective To investigate the effectiveness of percutaneous intracystic steroid injection using two needles in the treatment of solitary bone cysts in children. Methods A total of 28 children with solitary bone cyst underwent steroid injection from January 1996 to January 2004. Under fluoroscopy, two fine needles (either bone marrow biopsy needle or lumbar puncture needle) pierced the bone cyst by way of the top and the bottom of the cyst, respectively. The intracystic fluid was drawn off, the cyst cavity irrigated and the steroid injected into. Results Follow-up checkups for 10~62 months (mean, 28 months) in 27 children found no complications. According to the Chigira classification on the new bone formation, 20 cases were classified as grade Ⅳ, 5 case grade Ⅲ, 1 case grade Ⅱ and 1 case grade Ⅰ, the cure rate being 92 6% (25/27). The time for bone cysts to grow together again in the 25 children was 3~10 months (mean, 4 5 months). Conclusions Percutaneous intracystic steroid injection using two needles for solitary bone cysts in children is simple, safe and effective.

This study was aimed to establish the method for fraction-splitting of seeds of Descurainia sophia, in order to study the stability and unoverlapping property of fractions of seeds of D. sophia. The fraction-splitting of seeds of D. sophia were obtained through the combination of various methods including decoction, distillation, extraction, ethanol precipitation and gradient elution of macroporous adsorption resin. HPLC and chemometrics software were used to analyze the stability and unoverlapping property of the fractions of D. sophia. The results showed that the chemical components from seeds of D. sophia was divided into six fractions. HPLC data and chemometrics analysis showed good stability of technology. The fraction-splitting of seeds of D. sophia was unoverlapping. It complied with the research model of chemical constituents of seeds of D. sophia which can be split and combinatorial. It was concluded that the established method for splitting fractions of seeds of D. sophia had good stability and repeatability. Each splitting fraction uncrossed others.

Objective To assess the relationship between type 2 diabetes and the risk of kidney cancer. Methods PubMed, Medline, CNKI and VIP were used to identify studies which regarded the relationship between type 2 diabetes and risk of kidney cancer up to July 2014. The relative risks (RRs) and the corresponding 95% confidence interals (CIs) were used to estimate the association between type 2 diabetes and the risk of kidney cancer through software STATA. Results 8 studies were included in this analysis. Compared to the popula-tion without type 2 diabetes, there was an increased risk of kidney cancer in the type 2 diabetes patients, the pooled RR (95%CI) was 1. 55 (1. 24,1. 92),P<0. 05. Conclusion Our meta-analysis suggestes that type 2 diabetes can increase the risk of kidney cancer.

Objective:To comprehensively evaluated the quality of Sargentodoxae Caulis from different habitats with a combination of indexes and characteristic chromatogram method from Chinese Pharmcopoeia (Edition 2020). Methods:The contents of water content, total ash, ethanolic extract, sulfur dioxide residue, heavy metals and harmful elements, total phenols, chlorogenic acid, salidroside and characteristic chromatogram of 17 batches of Sargentodoxae Caulis were determined. The quality of Sargentodoxae Caulis was comprehensively evaluated by combining chemical pattern recognition method. Results:The water content, total ash content, extracts, and content determination of 17 batches of Sargentodoxae Caulis from different habitats complyed with the provisions of the Chinese Pharmcopoeia (Edition 2020). There were differences in the contents of extracts, chlorogenic acid, and salidroside, among which the content of Anhui origin was higher. A total of 8 common peaks were identified from the 17 batches samples. Conclusion:Comprehensive evaluation of multiple indicators can demonstrate the quality of Sargentodoxae Caulis more correctly, and shows that the quality of Sargentodoxae Caulis from different habitats is different. The quality of Sargentodoxae Caulis from Anhui is better than that from other habitats.

Objective:To establish the quality evaluation method of Perillae caulis formula granules based on the three kind of quality indexes of standard decoction. Methods:Eighteen batches of Perillae caulis were collected from different habitats according to different technical requirements, eighteen batches of standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The content of Caffeic acid and Rosmarinic acid were determined and calculated by Ultra High Performance Liquid Chromatography (UPLC). Then the fingerprints of standard decoction of and formula granules of Perillae caulis were established by UPLC . The similarity values of fingerprints between formula granules and standard decoction were calculated. Results:The average paste-forming rate of standard decoction was (7.16±1.97)%. The paste-forming rates of three batches of formula granules were 5.52%, 5.25% and 5.34%, respectively. The average content of Caffeic acid and Rosmarinic acid in standard decoction was (12.06±3.37)mg/g. The contents of three batches of formula granules were 5.52, 5.82, 5.77 mg/g, respectively. Seven common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, three of which were identified as Caffeic acid, N-Feruloyl Octopus amine and Rosmarinic acid by comparison of reference substance. The fingerprints similarity of Perillae caulis dispensing granules and standard decoction were 1.000, 0.995 and 0.997, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method can provide basis for the establishment of quality standard of Perillae caulis dispensing granules.
