Objective:To develop a qualitative analysis model for the fast identification of Dens Draconis and its adulterants by NIR correlation coefficient method. Methods:On the basis of the traditional morphological identification, the spectra were collected u-sing the fiber accessory of a near-infrared spectroradiometer. The reference spectra were set up using the NIR spectra of certified Dens Draconis. The characteristic spectral section was chosen and the appropriate threshold was set to establish a qualitative analysis model for the rapid identification of Dens Draconis and its adulterant. Results:The spectral section of 5 000-4 200 cm-1 was selected as the characteristic spectral section, the correlation coefficient of Dens Draconis and its adulterant was calculated in training set samples, and 92. 67% was used as the threshold. Totally 10 batches of validation set samples were validated the qualitative analysis model, and the prediction accuracy was 90%. Conclusion:The method has good prediction ability, and can be used in the rapid identification of Dens Draconis and its adulterant.

This study was aimed to establish a qualitative model of near-infrared spectroscopy in order to accurately and rapidly identify several mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs. The near-infrared diffuse reflectance spectroscopy combined with OPUS software was used to analyze the spectral characteristics of these samples. The pattern recognition method was explored through cluster analysis. And the accuracy of the model was verified. The results showed that these mineral Chinese medicinals from fossil had their characteristics absorption so that they can be quickly and accurately differentiated from each other through pattern recognition method. It was concluded that based on near-infrared spectroscopic mod-eling, these mineral Chinese medicinals from fossil including Os Draconis, Dens Draconis, Fossil Shell of Spirifer, and Fossil Crabs can be quickly and accurately identified.

Compared with that for botanical drugs and animal-derived drugs, the identification study for mineral traditional Chi-nese medicines is relatively weak. The traditional identification methods can’ t meet the quality control requirements of mineral tradi-tional Chinese medicines, and the application of modern analysis techniques are needed urgently in the systematic research of mineral traditional Chinese medicines. In the paper, the identification of traditional methods combined with some modern analysis techniques such as X-ray diffraction, near infrared spectroscopy and Raman spectroscopy for mineral traditional Chinese medicines was summarized and analyzed to provide basic idea and methods for the systematic identification construction of mineral traditional Chinese medicines.

Objective To detect the mutation of CARD15 gene in a patient with sarcoidosis and tuberculosis.Methods Clinical data were collected from a 32-year-old male patient with early-onset sarcoidosis and tuberculosis.Peripheral blood was obtained from the patient,both of his parents,and 102 healthy controls.All the 12 exons of the coding regions as well as flanking intronic sequences of the CARD15 gene were amplified by PCR followed by direct sequencing.The resulted sequences were blasted against the reference sequences of CARD15 gene.Results Both clinical features and histopathological findings of the patient were consistent with sarcoidosis.Furthermore,the patient presented with flexion contractures of fingers and toes,as well as iridocyclitis.A heterozygous missense recurrent mutation c.1000C ＞ T (p.R334W) was detected in exon 4 of the CARD15 gene in the patient,but not in either of his parents or any of the 102 healthy controls.Conclusions A p.R334W mutation in the CARD15 is identified in the patient,which may be responsible for the clinical phenotype of earlyonset sarcoidosis.Gene analysis may be a useful method to clarify the etiology of early-onset sarcoidosis.

Objective To observe the ultrastructural features of recessive dystrophic epidermolysis bullosa inversa(RDEB-Ⅰ)and to detect the mutations of COL7A1 gene in a family with RDEB-Ⅰ.Methods A 24-year-old male patient complained of recurrent vesicles in the skin for 24 years.The lesions began as generalized pruritic vesicles and bullae soon after birth,with a predilection for areas subject to friction,and showed a trend to be worse in summer but mild in winter.No photosensitivity was observed.When he was 3 to 4 years old,the lesions were decreased in number,with the only involvement of the trunk and abdomen;thereafter,the lesions were improved year by year.The patient suffered from nephritis at the age of 5 years,which progressed into renal failure at the age of 15 years.He received renal transplantation and was given long-term oral tacrolimus and mycophenolate mofetil,which leaded to an improvement in the lesions.The family history was unremarkable,and the marriage between her parents was not consanguineous.Dermatological examination revealed large areas of irregularly-marginated,hypopigmented,atrophic scar on the waist,back and abdomen with onychodystrophy involving multiple nails.No vesicles were observed.Immunofluorescence antigen mapping and transmission electron microscopy were conducted to observe the expression of type Ⅶ collagen in and ultrastructure of cutaneous lesions from the patient.Venous blood samples were obtained from the patient as well as his parents and 3 sisters,and drill biopsy specimens were obtained from the margin of vesicular lesions and unaffected anterior tibial skin of the patient.DNA specimens were obtained from the blood samples of the family members and 150 unrelated healthy controls,and RNA was extracted from the biopsy samples of the patient.PCR and direct sequencing were carried out to detect mutations in COL7A1 gene,and reverse transcription-PCR was conducted to confirm the mutation at mRNA level.Results Skin cleavage was observed under lamina densa in the dermis,with a decrease in anchoring fibrils and expression of type Ⅶ collagen in the lesions of the patient.A heterozygous synonymous mutation c.C5499T which created a new splicing site and leaded to a premature terminal codon,as well as a heterozygous missense mutation c.C6205T(C-T transition at codon 2069:CGT to TGT)which leaded to the substitution of arginine by cysteine,were identified in the COL7A1 gene of the proband and all of his sisters,but not in any of the unrelated controls.The c.C5499T and c.C6205T mutations were inherited from the patient's father and mother respectively.Conclusion The compound heterozygous mutations c.C6205T and c.C5499T may be responsible for RDEB-Ⅰ in this patient.

s:Objective Discuss the application of CTA for renal vascular control in laparoscopic renal transplantation of relative renal donors. Methods 83 cases of relative renal transplantation donors which are completed in our department during March 2007 to Junuary 2012 were divided into 3 Groups. There were 35 cases in group A ( laparoscopic nephrectomy with preoperative CTA examination) , 15 cases in group B ( laparoscopic nephrectomy without preoperative CTA examination) , and 33 cases group C ( conventional nephrectomy) . In group A, the location and quantity of renal arteries and veins were observed with preoperative CTA to make plan for vascular control. And the oper-ation time, amount of bleeding, vascular injury cases, the renal warm ischemia time in the graft, mean time of postoperative hospitalization were compared with those of group B and group C. Results 5 cases of renal vascular anomalies were observed in Group A, including 2 cases of single accessory renal artery, 2 cases of early branch of renal artery and 1 case of double renal veins. And all of them were intraoperatively comfirmed. 3 cases of renal vascular anomalies were observed in group B, including 1 case of renal arteriovenous ectopic, 1 case of injury in the accessory renal artery with diameter of 0. 6 cm, and it were given artery elongation with inferior epigastric artery postoperatively, and 1 case of renal vein injure during blocking lumbar vein with Hemolock which were repaired postoperatively. 5 cases of renal vascular anomalies were observed in group C, including 1 case of single accessory renal artery, 3 cases of early branch of renal artery, and 1 case of accessory renal artery with the diameter of 0. 1cm in the right renal was injured during surgery. The operation time, amount of bleeding, cases with vascular injury , renal warm ischemia time of donor , and the mean time of postoperative hospitalization in group A were superior to those in group B and group C. Conclusion CTA is a simple noninvasive imaging method, which can provide the details of the renal vascular preop-eratively to ensure the safety of patients during surgery and improve survival quality of donor renal, and it is of great advance in laparoscopic renal transplantation of living-related renal donors.

Objective To evaluate the impact of postoperative adjuvant chemotherapy on prognosis of patients with advanced rectal carcinoma using a meta-analysis.Methods We searched PubMed to identify literature comparing observation with adjuvant chemotherapy after neoadjuvant chemoradiotherapy and surgery for patients with advanced rectal carcinoma.Data were analysed using Revman 5.0 statistical software.Results Nine trials were included consisting of 6 212 patients:3 421 patients received adjuvant chemotherapy and 2 791 patients did not.The age ranged from 55.6 to 68 years.Adjuvant chemotherapysignificantly affects overall and disease-free survival (P =0.002 and P =0.000 5 respectively) of patientswho had received neoadjuvant chemoradiotherapy.The subgroup analysis which originate from insufficient data reveales ypT0-2 patients and ypT3-4 patients can't benefit from adjuvant chemotherapy.Conclusion Postoperative adjuvant chemotherapy can improve the survival of advanced rectal carcinoma patients after neoadjuvant chemoradiotherapy,but can't increase the survival of pathology complete respone and yPN + patients.

Objective To explore the effect of “double reinforcing and one unblocking” electroacupuncture on hepatic mitochondrial structure and ATPase activity in a rat model of senile yang deficiency. Methods Forty 5-month-old male SD rats were selected and randomly allocated to groups A, B, C and D, 10 rats each. Group A was a normal control group. A model of senile yang deficiency was made by 40 days’ subdermal injection of D-galactose and then 7 days’ intramuscular injection of hydrocortisone in the other three groups of rats. Group C received treatment with “double reinforcing and one unblocking”electroacupuncture at points Guangyuan(CV4), Zusanli(ST36) and Baihui(GV20); group D, treatment with electroacupuncture at points Zhongji(CV3), Yinlingquan(SP9) and Yintang(GV29). Treatment was given 6 times a week for a total of 4 weeks. After treatment, the anti-fatigue ability was determined by swimming exhaustion time, hepatic mitochondrial structure was observed under a transmission electron microscope and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities were measured by colorimetry in every group of rats. Results The mean swimming exhaustion time shortened significantly (all P＜0.01); hepatic mitochondrial inner and outer membranes were blurred, mitochondrial ridges deformed, ruptured or disappeared and mitochondria swelled; both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P＜0.01, P＜0.05) in groups B, C and D of rats compared with group A. Swimming exhaustion time lengthened significantly (P＜0.01), hepatic mitochondrial structure improved significantly and both Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities increased significantly (P＜0.01, P＜0.05) in group C compared with group B. Rat mean swimming exhaustion time shortened (P＜0.05), hepatic rough endoplasmic reticula degranulated and hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities decreased (P＜0.05) in group D compared with group B. Conclusion “Double reinforcing and one unblocking”electroacupuncture can improve anti-fatigue ability, ameliorate hepatic mitochondrial ultrastructure, increase hepatic Na+-K+-ATPase and Ca2+-Mg2+-ATPase activities and promote hepatic energy metabolism in a rat model of senile yang deficiency.
