Objective To study the application of microelectrode stereotactic functional nucleus lesioning operation in the treatment of Parkinson′s disease(PD) ,and to explore its clinical value .Methods The clinical data in 84 cases of PD treated with‐out using the microelectrode stereotactic functional nucleus lesioning operation(observation group) and 74 cases of PD treated by u‐sing microelectrode guided stereotactic functional nucleus lesioning in our hospital were retrospectively analyzed .At the same time the Unified Parkinson′s Disease Rating Scale (UPDRS) scores before the nucleus lesioning and at postoperative different medication states were obtained in the observation and the control group .Furthermore the difference of the UPDRS motor scores before and af‐ter operation were compared between the two groups .Results The UPDRS motor scores at postoperative 3 ,6 months and 1 year in the observation group were significantly improved compared with before operation(P<0 .05) ,meanwhile the postoperative anti‐PD drug dosage was significantly decreased compared with before operation(P<0 .05) .Among them ,70 cases(83 .3% ) in the control group were obviously effective ,14 cases(16 .7% ) were effective ,and the total effective rate was 100% ;while 62 cases(83 .7% ) in the observation group were obviously effective ,12 cases (16 .3% ) were effective ,and the total effective rate was 100% .The differ‐ence in improving the UPRDS motor scores before and after operation had no statistical difference between the two groups(P>0 .05) .Conclusion Stereotactic nucleus lesioning in treating PD has satisfactory effect and can significantly improve the UPRDS motor scores .Accurate positioning is the key to the operation success ,whether microelectrode recording can significantly improving the operation accuracy needs further discussion .

Objective To explore the effect of robot-assisted gait training on the standing and walking balance of persons with acute flaccid paralysis (AFP) resulting from hand-foot-and-mouth disease (HFMD).Methods Thirty-six persons with AFP resulting from HFMD were randomly divided into a control group and a training group,each of 18.Both groups were given conventional rehabilitation training,while the training group was additionally provided with robot-aided gait training.The control group received additional massage of their affected limbs.Before and after 15 days of treatment the subjects' standing and walking ability were evaluated using parts D and E of the gross motor function (GMFM) scale.Their balance was quantified using the Berg balance scale (BBS) and integrated surface electromyograms were recorded.Results There were no significant differences between the two groups before the treatment.After 6 weeks of treatment the average scores of both groups had improved significantly,with a significantly bigger increase observed in the training group.After the treatment,the average GMFM and BBS scores of the training group were significantly higher than those of the control group.Conclusion Gait training in addition to conventional rehabilitation training can significantly improve the standing,walking and balance of patients with HFMD resulting from AFP and promote their recovery.

Objective To determine the effects of non-thermal biological effect of low frequency pulsed electromagnetic field (LFPEF) with 15 Hz and 30 mT on ulcer wound during the plateau stress ulcer cure.Methods Thirty male Sprague-Dawley rats were assigned to three equal groups:control,normal cure group (NC) and exposure treatment groups (ET).The plateau rats stress ulcer models were constructed with the combination method of a hypoxic and low-pressure acclimation and the stimulation of absolute ethyl alcohol irrigating stomach.The LFPEF equipment generated the LFPEF of 15 Hz,40％ duty cycle and 30 mT to expose and treat the rats' stomach of ET group with the frequency of 3 hours each day.After 6 days of exposure treatment,the stress ulcer cure situation of each group was evaluated by the methods of macroscopic observation,the gastric juice pH values detection and ulcer index (UI) measurement.Results After 6 days of model,the macroscopic observation showed that the ulcer of NC group was worse than the that of ET group (P＜0.05).The pH values and UI of ET group were significantly different with those of NC group,and closed to those of the control group.Conclusion The nonthermal biological effect of LFPEF could promote the plateau stress ulcer cure.

Objective To determine the difference in blood microcirculation recovery between normal frostbite and high-altitude frostbite during the wound healing.Methods Twenty four male rats were randomly divided into control group (n=8), normal frostbite group (n=8), and high-altitude group (n=8). The normal frostbite group rats were frozen to produce mid-degree frostbite models by controlling the freezing time with liquid nitrogen penetration equipment. The high-altitude frostbite group rats were acclimated to a hypoxic and low-pressure environment for 1 week, and then the high-altitude frostbite models were constructed by the same way with liquid nitrogen penetration apparatus. On days 3, 7, 11, 15, 19, and 23 after modeling, the recovery situation of blood circulation of each group was observed with contrast ultrasonography by injecting SonoVue micro-bubble into rats' tail. Finally, the micro-bubble concentration (MC) was calculated to confirm the blood circulation recovery with software Image Pro. ResultsAt different time points, the wound area of the high-altitude frostbite group was bigger than that of the normal frostbite group, and the MC of control group was always about (27±0.2)×109/ml. On day 3, 7, 11, 15, 19, and 23, the MC was significantly lower in the high-altitude frostbite group than in the control group and normal frostbite group (P<0.05). The MC of normal frostbite group was significantly lower than that of the control group on day 3, 7, 11, 15 and 19 (P<0.05). In addition, no obvious difference in MC was found between normal group and control group on the 23th day (P<0.05).Conclusion The blood microcirculation recovery after high-altitude frostbite is significantly slower than the normal frostbite.

Objective Docetaxel is commonly used in chemotherapy for patients with mucoepidermoid carcinoma (MEC) in the salivary gland after operation,but it cannot kill all residual tumor cells and prevent recurrence.Cancer stem cells (CSCs) may be responsible for tumor recurrence and drug resistance.Based on the theory of CSCs,the authors investigated the effects of docetaxel on cancer stem cell-like cells in the MEC cell line MC3.Methods MC3 cells in the logarithmic growth phase were divided into a negative control and a docetaxel (40 ng/mL) group.The colony formation rate of the MC3 cells was calculated with the soft agar cloning technique,the growth of the cells detected by MTT assay,the protein and mRNA expressions of CD44 and Oct4 determined by immunocytochemistry and flow cytometry,and tumorigenicity observed by nude mouse tumorigenicity assay.Results Compared with the negative control group,the MC3 cells treated with docetaxel exhibited significant increases in the colony formation rate ([9.14±0.75] vs [33.47±1.30]％,P＜0.05),the protein expressions of CD44 (14.47±0.15 vs 99.50±0.30,P＜0.05) and Oct4 (1.37±0.06 vs 14.60±0.36,P＜0.05),and the mRNA expressions of CD44 (0.207±0.009 vs 0.651±0.015,P＜0.05) and Oct4 (0.223±0.008 vs 2.228±0.005,P＜0.05).At 2 months after injection of 1×103,1× 104,and 1×105 MC3 cells,tumor formation was observed in 0,1,and 3 of the nude mice,respectively,but not in the negative control group.Conclusion MC3 cells surviving docetaxel treatment have the properties of stem cells,and docetaxel can enrich cancer stem cells in the MC3 cells,which plays a key role in tumor recurrence.

Objective: The characteristics and differences of the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia were investigated to provide references and suggestions for the compilation of the Chinese Pharmacopoeia.
Methods: From the perspective of frame structure and main contents, the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia was compared.
Results: Each volume of the Chinese Pharmacopoeia had its general notice, including 34 to 48 items and 10 to 12 chapters based on different varieties collected in each volume. The Japanese Pharmacopoeia had 49 items not arranged by chapters. There are many differences on the general notice between the Chinese Pharmacopoeia and the Japanese Pharmacopoeia, such as the definitions and expressions of names, determination of appearance, revision rules, risk assessment and quality control conception. The framework of the general notice in the Chinese Pharmacopoeia was clear, the content was specific and the operation was friendly. The term description of the general notice in the Japanese Pharmacopoeia was concise, and some terms need to be implemented under the guidance of professional knowledge.
Conclusion: In light of comparative study, every volume’s general notice of the Chinese Pharmacopoeia has its own characteristics. By integrating advanced analytical technique, combining the requirements with laws and regulations, and optimizing content and terms, all volume’s general notice could be explored to be coordinated and unified.
