Objective To investigate the nursing of replantation methods of sea-water soaked rotated avulsion amputated fingers.Methods There were 8 cases (16 fingers) with sea-water soaked rotated avulsion amputated fingers.5 cases were replanted by synchronic replantation method,the other 3 cases were replanted by traditional replantation method.We adopted complete debridement and high quality vascular anastomosis during the operation,and give hyperbaric oxygen therapy and anticoagulant treatment post-operation.Results There were 15 survival fingers in 16 replanted fingers.The survival rate was 93.75％.After follow-up for three months to two years,the total good rate was 87.5％.No wound infection and nonunion of fracture occurred.The outline of the fingers was satisfying and patients felt well.The twopoint discrimination was 3～6 mm after 3～24 months follow-up.Conclusions The injury of sea-water soaked rotated avulsion amputated fingers is complicated and the replantation operation is difficult.but if we can adopt individual measure according to the actual circumstance,it is possible that the sea-water soaked rotated avulsion amputated fingers can survive.

Objective To research the serum urea nitrogen (BUN),creatinine (Cr),urinary inhibition C (CysC) and retinol binding protein (RBP) four biochemical indicators of joint detection on the early diagnostic value of lupus nephritis (LN).Methods According to the American Rheumatology Association (ACR) 2012 revision of the diagnostic criteria,collected 177 LN patients with kidney disease from January 2011 to April 2016 in Shaanxi Provincial People's Hospital,at the same time,choose 167 cases of healthy physical examination as normal control group.With Hitachi 7170A a fully automated analy zer on two groups of serum BUN,Cr,CysC and concentration of RBP for testing,the data obtained by SPSS17.0 statistical software for statistical analysis.Results LN patient group compared with healthy controls,the serum BUN (6.67 ± 1.43 mmol/L vs 6.57±1.16 mmol/L),Cr (96.9±10.1 μmol/L vs 92.6±13.2 μmol/L),CysC (1.7±0.5 mg/L vs 0.75±0.15 mg/L),RBP (180.5±8.28 mg/L vs 42.6±9.6 mg/L) concentrations were higher,and serum CysC,RBP higher level com pared with healthy control group difference was statistically significant (t=8.145,21.594,all P＜0.05).Single parameter detected abnormal rate in terms of LN patients serum BUN,Cr,CysC and RBP abnormal rates were 28.3％,29.4％,68.4 ％,65.0 ％,four indicators combined detection of abnormal rate was 85.3 ％,significantly higher than the single parameter test (x2 =35.973～168.742,all P＜0.01).Conclusion Conbined detection of BUN,Cr,CysC and RBP four early diagnosis of renal damage in patients with lupus nephritis had important clinical value.

The HPLC fingerprint differences ofRadix Platycodonis from different origins were studied to provide references for their quality control and production. The total platycodins were purified by DB101 macroporous resin. HPLC-ELSD fingerprints of the total platycodins for 39 batches ofRadix Platycodonis samples from 9 provinces were performed on an Agilent HC-C8 column (4.6 mm x 250 mm, 5μm) with gradient elution. The mobile phase was acetonitrile-0.5% acetic acid. The injection volume was 6μL. The flow rate was 0.5 mL·min-1. The temperature of drift tube was set at 90℃. And the gas flow (N2) was set at 1.2 mL·min-1. The results showed that there were large differences in the quality ofRadix Platycodonis from different origins with the common fingerprints of 6 batches of samples fromChifeng in Inner Mongolia as references. The quality ofRadix Platycodonis was closely related to the seeds, the ecological environment, the way of drying and storing and so on. It was concluded that it was important to strengthen the provenance base construction, standardization of the seeds, reasonable formulation of the regionalization, and standardization of the production processing for the cultivation and production ofRadix Platycodonis.

This study was aimed to compare the expectorant and antitussive actions ofPlatycodon grandilforum from different production areas in order to provide references for its cultivation and production. The antitussive activities ofP. grandilforum water extract from different areas were investigated through testing the cough times induced by ammonium hydroxide in mice. And the expectorant activities were studied by testing the amount of tracheal phenolsulfonphthalein excretion in mice. The results showed that the minimum effective dose ofP. grandiflorum fromChifeng of Inner Mongolia was 0.2 g·kg-1. Under this dosage,P. grandiflorum fromChifeng of Inner Mongolia can significantly reduce the cough frequency in mice (P < 0.01), and significantly prolong the cough incubation period in mice (P < 0.01).P. grandiflorum fromSichuan province,Shangzhou ofShaanxi province andChongqing can significantly decrease the cough frequency in mice (P < 0.05). P. grandiflorum from Sichuan province,Shangzhou ofShaanxi province andChifeng of Inner Mongolia can significantly increase the phenolsulfonphthalein excretion quantity in mice (P < 0.05). It was concluded thatP. grandilforum was effective for relieving cough and removing sputum. The effect ofP. grandilforum fromChifeng of Inner Mongolia was obviously stronger than that from other areas.

Objective:To evaluate the application of visual feedback coaching method, which is embedded in an optical surface monitoring system, in deep inspiration breath holding during the radiotherapy in left breast cancer patients after breast-conserving surgery.Methods:Thirty patients with left breast cancer, who were scheduled to receive the whole breast radiotherapy after breast-conserving surgery, met the requirements of deep inspiration breath holding after respiratory coaching with the visual feedback coaching module in the optical surface monitoring system. Active breathing control equipment was used to control breath-holding state and CT simulation was performed. During treatment, optical surface monitoring system was used to guide radiotherapy. All patients were randomly divided into two groups. In group A ( n=15), visual feedback respiratory training method was utilized and not employed in group B ( n=15). In group A, the visual feedback coaching bar of the optical surface monitoring system was implemented, while audio interactive method was employed to guide patients to hold their breath. Real-time data of optical body surface monitoring were used to compare the interfraction reproducibility and intrafraction stability of breath holding fraction between two groups. Besides, the number of breath holding and treatment time per fraction were also compared. GraphPad prism 6.0 software was used for data processing and mapping, and SPSS 21.0 software was used for analyzing mean value and normality testing. Results:Compared with the control group, the reproducibility in the experiment group was reduced from 1.5 mm to 0.7 mm, the stability was reduced from 1.1 mm to 0.8 mm, the mean number of breath holding required per fraction was decreased from 4.6 to 2.4, the mean beam-on time per fraction from 336 s to 235 s, and the treatment time per fraction was shortened from 847 s to 602 s (all P<0.05), respectively. Conclusions:The application of visual feedback coaching method can improve the reproducibility and stability of breath holding during radiotherapy for left breast cancer, and it can also effectively reduce the number of breath holding and shorten the treatment time per fraction.
