Objective To determine the plasma concentration of cytarabine(Ara-C) in children with leukemia and obtain dynamics parameters, and investigate the relationship between the parameters and clinical effect in order to provide the basis for optimization of Ara-C application. Methods Using highperformance liquid chromatogram (HPLC) to determine the plasma concentration of Ara-C, its metabolite Ara-U and infusion rate in 37 children with acute leukemia, their therapeutic reaction, remission, treatment-related infection, side-effect and long-term treatment effect were analyzed in statistic. Results Ara-C by 1~2 g/m2 intravenous drop infusion for 2 hours, the peak plasma concentration time was 2 h and peak concentration were (14.37-84.44)μmol/L, and the median was (41.42±22.80)μmol/L. The median infusion rate was 869.57at 30 minutes after Ara-C drip completion, its average level was (253.40±81.49) μmol/L, over six-times than Ara-C peak concentration. The median continuous complete remission time in 37 children was 29.8 months (5.0~53.1 months), 3y-DFS was (90.63±5.15)%. The therapy-related infection rate was 56.8 %(21/37),including three children (8.1 %) suffered from severe infection, but there was no therapy-related death and no children were off the protocol due to poor tolerance. Conclusion As post-remission treatment, high-dose Ara-C would not cause cumulation in vivo in children with acute leukemia and side-effect were slight. Ara-C could improve the long-term continuous complete remission rate and clinical cure rate for children with leukemia. Therefore, it was worth to apply in clinical.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

OBJECTIVETo compare the effect of massage alone or in combination with pricking collateral blood therapy (PCBT) on mild carpal tunnel syndrome (CTS).
METHODSSixty cases with mild CTS were randomly assigned into two groups, the control group treated with massage therapy alone, and the treated group with PCBT at the six Jing points of the affected upper limb combined with massage, 30 cases in each group. The therapy was conducted in all patients for 3 courses. The therapeutic effect was observed and the differential value (D-value) of sensory conduction velocity (SCV) between the median and ulnar nerves of the fourth digit (D4) was detected before and after each course of therapy.
RESULTSAfter 3 treatment courses, excellent, therapeutic effect was shown in 26 patients and good effect in 4 of the treated group, while in the control group, the effect was excellent in 8, good in 20, and improved in 2. The effect was better in the former group than that in the latter (P<0.05). Marked difference in the D-value of SCV was shown at the end of each course in both groups (P<0.05). As compared it between the two groups, significant difference was shown at the end of the 1st and 3rd course respectively (P<0.05).
CONCLUSIONCombined treatment of massage and PCBT showed better effect on mild CTS than massage therapy alone, and the onset time may positively correlated to the frequency of applying PCBT.

Objective To investigate the application technology and effect of Navien catheter in intracranial aneurysms embolization.Methods The clinical data of 15 patients with intracranial aneurysm treated with Navien catheter in Department of Neurosurgery of Yijishan Hospital Affiliated to Wannan Medical College from March to December 2016 were analyzed retrospectively. The extracranial segments of internal carotid arteries were seriously tortuous in all patients. The coaxial system was used during procedure. Whether the Navien catheter could be smoothly placed into the target artery or not was observed,and the coils or stent-assisted coils were used to embolize the intracranial aneurysms in the corresponding positions. The immediate embolization results were assessed by the Raymond grading. The intraoperative and postoperative complications were observed and the patients were followed up by imaging.Results All 15 patients had abnormal tortuosity of extracranial segments of internal carotid arteries. The Navien catheter was able to smoothly pass through the tortuous vessels and reach the desired position. The stent-assisted coil embolization was used in 9 patients,and the coil embolization was used in 6 patients. The success rate of the coil and stent placement technology was 100%. The stents were all accurately put in place without shift. According to the Raymond grading,the immediate embolization rate of aneurysms showed that 15 patients achieved Raymond gradeⅠ. One case developed internal carotid spasm during the procedure. The patient was improved after giving papaverine. Others did not have intraoperative complications,such as cerebral vasospasm,vascular dissection,in-stent thrombosis,and intraoperative aneurysm rupture. Five patients were followed up for 3 to 6 months with digital subtraction angiography (DSA). There was no recurrence of aneurysm and no in-stent stenosis and shift,No rebleeding or cerebral ischemia was observed.Conclusion Forpatients with severely tortuous in extracranial segments of internal carotid artery,using the Navien catheter may overcome artery tortuosity and other unfavorable factors of the patients and successfully reach the target vessel position,enable the embolization of intracranial aneurysms to be completed successfully.
