This article described the current status of problems in quality and safety in TCM industry. It also emphatically discussed the quality and safety control in TCM production process. In addition, this article used the HACCP (Hazard Analysis and Critical Control Points) system to conduct a hazard analysis on TCM production process and determined the critical control points, and carried out the corresponding control measures, with a purpose to realize effective regulation and control of hazard factors and ensure TCM quality and safety.

BACKGROUND: Laser facial skin resurfacing has become a method of treatment for photoaging and pigmentary conditions. Although excellent results can be obtained by high-energy, pulsed carbon dioxide(CO2) laser, significant morbidity exists due to the considerable thermal damage to the skin. The Erbium: Yttrium Aluminum Garnet(Er: YAG) laser, with a wavelength of 2940 nm, is well absorbed in water. This leads to a very small zone of thermal necrosis, compared ta the CO2 laser. OBJECTIVE: The purpose of this study was to evaluate the results of the combined use of the char-free CO2 laser and the Er: YAG laser in the treatment of facial wrinkles. METHODS: Forty-six patients, aged between 30 and 68 years, with facial wrinkles, were evaulated. Two types of resurfacing laser systems were utilized in this study, a high-energy, short-pulsed CO2 laser and a Er: YAG 1aser. Wrinkle improvement was evaulated by the patients satisfaction, clinical improvement, and photographic analysis before and after the resurfacing procedure. RESULTS: Twenty-six of the 46 patients had greater than an 80% improvement, and 19 patients had a 60-80% improvement. Only one patient showed a 50% or less improvement. CONCLUSIONS: The combination of char-free CO2 laser and Er: YAG laser for facial wrinkles is a safe and effective modality for laser skin resurfacing.

Letterer-Siwe disease in an acutely onset, progressive and fatal disorder of RES, usually appears in male children, chareacterized by constitutional signs and extraos-seous lesions. This case occurred in a 18-day-old female showing hepatomegaly, hemorrhagic crusted papular eruptions on the entire body, and abdominal distension. Direct smear of scraping materials from the skin lesion showed numerous histiocytes. Hematologic and other laboratory examinatons showed no abonormalities.

Objective To study an identified leucine-rich repeats(LRRs)protein,LRR containing 19(LRRC19),and to determine the distribution,localization,and biological function of LRRC19 mRNA expression in spleen cells.Methods Bioinformatics analysis was used to predetermine the structure of LRRC19 gene and protein.The distribution and localization of LRRC19 mRNA expression were detected by hybridization in situ with LRRC19 mRNA specific probes and reverse transcriptase polymerase chain reaction(RT-PCR).Additionally,the activity of secreted alkaline phosphatase(SEAP)was detected for analyzing the nuclear factor-kappa B(NF-?B)activation in HEK293T cells transfected with the expression vector of LRRC19 in vitro.Results LRRC19 was found to be a transmembrane protein,with 4 LRR motifs,a single transmembrane domain and two phosphorylation sites of casein kinase 2(CK2)at cytoplasmic domain,as analyzed through bioinformatics soft wares.Previous study revealed that LRRC19 without cytoplasmic Toll/IL-1 receptor(TIR)domain could activate NF-?B to enhance the expression of proinflammatory cytokines.LRRC 19 could also be demonstrated by ectopic expression in RAW264.7 cells after transfection with murine LRRC19 expression plasmid pcDNA3.1-V5-LRRC19 indicating that it was a transmembrane protein.In persent study,the results of hybridization in situ and RT-PCR showed that LRRC19 mRNA was expressed in the germinal center and splenic cord of mouse spleen.Additionally,LRRC19 was predominantly expressed in CD5+ lymphocyte,known as B1 cell.In vitro study also indicated that several pathogens might significantly enhance the NF-?B activity of the cells transfected with LRRC19.Conclusion LRRC19 might be a transmembrane receptor,and it may be able to recognize the conserved sequence of pathogens,participate in the induction of cell signaling,activate the NF-?B signal pathway,promote transcription of target genes,and modulate the innate immune response.

Objective To investigate the correlation between blood pressure variability and variabilities of some feature variables extracted from photoplethysmography (PPG) signal.Methods Continuous blood pressure (BP) and PPG signal were collected simultaneously from 19 healthy subjects under rest and after exercise.Eight feature variables were extracted from the PPG signal.The relationship between the beat-to-beat variability of BP and feature variables extracted from PPG were quantified by calculating Person's correlation coefficient.Results The variability of the amplitude of PPG was highly correlated with systolic BP variability both under rest (0.75) and after exercise (0.76).Meanwhile,the correlations between systolic BP variability and the variability of the time from the trough to the dicrotic north were 0.74(under rest) and 0.78(after exercise).Conclusion The amplitude variability of PPG is highly correlated with systolic BP variability and can be potentially used for monitoring BP variability.

Background and purpose: VATS lobectomy has gained popularity for lung tumor around the world during the recent twenty years.Complete anatomic resections and node dissections are routinely being performed at many centers under VATS, but some thoracic surgeons are concerned regarding the safety, benefit and radical resection of this operative method. Our study was aimed to evaluate the reliability and feasibility of pulmonary resection and lymphadenectomy by video-assisted mini-thoractomy (VAMT) for patients with lung tumor.Methods:From August to September 2006,radical lobectomy or pneumonectomy and systemic lymphadenectomy were performed on 9 patients with lung tumor through video assisted mini-thoracotomy surgery.incidence of complications, total number of dissected lymph nodes,number of metastatic lymph nodes,survival and life quality were evaluated.Results:Totally 100 lymph nodes were removed at average 15.0 minutes, and there was no accident and death happened in the whole operation which only consumed 2.3 hours. Serious postoperative complications and death also did not happen.Conclusions:Video assisted mini-thoracotomy surgery should fulfill the same quality lymphadenectomy and lung tumor definitive resection.

OBJECTIVE:To discuss the role of Chinese materia medica preparations in hospital traditional Chinese medicine work for references of the development of Chinese materia medica preparations in hospital. METHODS: The importance and role of the research & development, preparation and use of hospital Chinese materia medica preparation in the development chain of Chinese medicine were analyzed. RESULTS & CONCLUSION: The research and preparation of hospital Chinese materia medica preparation make up for the deficiency of the industrial production of Chinese materia medica preparations and play a part in the inheritance and innovation of traditional Chinese medicine.

Objective Compared with povidone iodine solution to clean,glutaraldehyde immersion,highpressure steam sterilization of three disinfection methods for dental handpiece sterilization effect.Methods Select the 20 dental clinical used over phone,were randomly divided into A group,B group,C group,D group 5,A group for the control group,only cleaning method did not use any disinfection,B group was 1% Polyvinylpyrrolidone iodine solution,wipe,C group were soaked in 2% glutaraldehyde soluton,D group were treated with high-pressure steam sterilization,after each phone were inoculated with bacteria sample dish,the more monitoring of four groups of bacterial culture.Results A group of bacterial culture for the intensive growth of bacteria,B group had bacterial growth for the(+ ～+ + +),bacterial growth;C group had bacterial culturegrowth was(+ ～ + +),bacterial growth;D group of bacterial culture Growth of(-),no bacterial growth.Conclusion High-pressure steam sterilization was the disinfection of dental handpieces most effective way.
