Journal of Clinical Hepatology 2012;28(1):14-16
Objective To investigate the clinical application value, efficiency and safety of precut sphincterotomy in endoscopic retrograde cholangio-pancreatography (ERCP) .Methods From January 2008 to June 2011, 930 patients received ERCP in the department of hepatobiliary surgery of the first hospital of Jilin University.Of them 108 cases (11.6%) were diverted to receive precut sphincterotomy, because selective bile duct cannulation with conventional method was difficult.Inclusion criteria: failure of conventional cannulation or repeating pancreatic duct cannulation for more than 4 times.According to the patient's conditions, the examination and treatment of ERCP was carried out.Observation termination are therapeutic success rate and the incidence rate of complications, and comparative analysis on case data of routine ERCP was made.Statistical analysis was executed by SPSS 13.0 software.Comparison of ratio were determined with χ2 test, a value less than 0.05 was considered as significant.Results Of 108 cases, the success rate of ERCP was 95.4% (103 cases) .The incidence rate of complications was 6.5%, and there are no cases of duodenal perforation and death.Amongst 822 cases of routine ERCP, therapeutic success rate was 97.7%, and the incidence rate of complications was 7.7%.The statistics analysis result indicates that there are no statistical differences between precut sphincterotomy group and routine ERCP groups in the success rate (χ2=2.041, P=0.153) and the incidence rate of complications (χ2=0.141, P=0.707) .Conclusion The precut sphincterotomy in ERCP are safe and obviously effective with less complications compared to routine ERCP.The successful probability of difficult ERCP is improved greatly by using the technique of precut sphincterotomy.But the precut sphincterotomy indication is strictly controlled, and the technique should be performed by experienced endoscopist.

Clinical Medicine of China 2012;28(6):654-655
Objective To retrospec the efficacy of percutaneous nephrolithotomy on treatment of urinary tract stones in solitary kidney.Methods From June 2008 to April 2011,percutaneous nephrolithotomy technique was used to treat 20 cases of urinary tract stones,with kidney stone or cast form staghorn calculi in 4 cases,single pelvis,calyceal stones 10 cases,6 cases of upper ureteral calculi;Fourteen cases used the standard channel F24;6 cases used F16 Micro Channel.Among the 20 patients,16 cases performed stage Ⅰ single channel surgery;2 cases performed dual-channel surgery in Ⅰ stage;2 patients with severe infection performed stage Ⅱ single channel surgery.Results The average duration of the operation was 66mins.The stone clearance rate was 88.36% on average(18/20),without laceration or bleeding of pelvis or renal calyces mucosa or any other complications.Postoperative indwelling nephrostomy tubes were removed 6 -7 days later,without complications found during the follow-up period.For the 6 cases with preoperative renal dysfunction before surgery,the levels of blood Cr decreased at 2 weeks after surgery.Conclusion Compared to open surgery,percutaneous nephrolithotomy is safe and effective with small wound in treatment of solitary kidney with invasive upper urinary tract calculi.

6.DSP-based design of family health monitor
International Journal of Biomedical Engineering 2009;32(5):280-282
Objective To design a new portable vital signs monitor for family use. Methods TMS320F2812, a kind of digital signal processor, was applied as the main processor to control the functional mod-ules including A/D convertor, LCD display. Bluetooth communication module was introduced to achieve real-time fast transfer of data between the system and the PC. Results Not only can the system monitor electrocardiogram (ECG), breath rate, pulse rate, body temperature and other vital signs accurately, but also it runs stably. Conclusion The features of DSP and Bluetooth were well combined in the design of the family-oriented, easy to use, multi-functional monitor with small size, low power consumption and convenience. A broad application and market prospects can be predicted.

International Journal of Traditional Chinese Medicine 2015;(3):258-260
ObjectiveTo explore the content of isorhynchophylline in different medicinal parts of Ramulus Uncariae Cum Uncis.MethodsHPLC was adopted to determine 8 batches of different Ramulus Uncariae Cum Uncis of different origin and different medicinal parts. The Waters Symmetry C18 color(4.6 mm×250 mm, 5μm) was used with mobile phase of methanol -0.01 mol/L ammonium acetate buffer(pH 8.0)(60∶40), column temperature of 25℃ , 20μl sample volume, velocity of 1.0 ml/min, and detection wavelength of 246 nm. ResultsIsorhynchophylline can be detected in all 8 batchs of Ramulus Uncariae Cum Uncis in different regions, and different content were found among different origins. The content of isorhynchophylline in different parts of the same origin showed a decreasing sequence of the rhabd, stem with hook, stem without hook, and twig without hook and leaves.ConclusionMost of medicinal part of Ramulus Uncariae Cum Uncis contains isorhynchophylline, which provide a lab basis for exploring medicinal parts of this herbal medicine.

Journal of International Oncology 2012;(11):848-850
EML4-ALK fusion oncogene represents a new molecular target which appears mainly in lung adenocarcinoma.EML4-ALK is detected more frequently in young non-small-cell lung cancer patients who never or light smoke.ALK inhibitors(crizotinib)for the treatment of the EML4-ALK-positive non-small cell lung cancer has a high response rate.This finding can improve the individual treatment of non-small cell lung cancer.
10.Keli-Paoxi power for the treatment of acute paronychia
International Journal of Traditional Chinese Medicine 2017;39(3):212-214
Objective To evaluate the curative effect of Keli-Paoxi power for the treatment of acute paronychia. Methods A total of 144 patients with acute paronychia were randomly divided into a Keli-Paoxi power group, a mupirocin ointment group and an ethanol soaking group, 48 in each group. All patients were treated for 3 weeks and followed-up for 2 months. The time to regression of redness and swelling in the nail groove was recorded. The Visual Analogue Scale (VAS) was used to assess tenderness. The curative effects were evaluated, and recurrence of paronychia was recorded. Results The time to regression of redness and swelling in the nail groove in the Keli-Paoxi power group (2.2 ± 0.6 d) was significantly shorter than that in the mupirocin ointment group (8.1 ± 1.7 d) or ethanol soaking group (7.9 ± 1.2 d; F=344.597, P<0.01). The VAS Scores in the Keli-Paoxi power group (1.2 ± 0.2) was significantly lower than that in the mupirocin ointment group (3.2 ± 0.3) or ethanol soaking group (3.1 ± 0.3; F=831.273, P<0.01). The total effective rate in the Keli-Paoxi power group (100.0%, 48/48) was significantly higher than that in the mupirocin ointment group (83.3%, 40/48) or ethanol soaking group (81.3%, 39/48; χ2=9.700, P=0.008). The recurrence rate of paronychia in the Keli-Paoxi power group (2.1%, 1/48) was significantly lower than that in the mupirocin ointment group (16.7%, 8/48) or ethanol soaking group (14.6%, 7/48; χ2=6.000, P=0.049) at 2 months follow-up. Conclusions Keli-Paoxi power can alleviate tenderness, shorten the time to regression of redness and swelling in the nail groove, decraese recurrence in patients with acute paronychia. The curative effect of Keli-Paoxi power is superior to mupirocin ointment and ethanol soaking in the treatment of acute paronychia.
