Objective To compare the effect of electroacupuncture at head points and body points on glucose metabolism of the cerebral motor function regions in normal subjects.Methods To observe the change of glucose metabolism of cerebral motor area in normal subjects between before and after acupuncture during the movement by PET.Talairach coordinates(Atlas of brain) and statistical parametric mapping(SPM) software were used to deal with the acquired imaging data.Results ① Acupuncture at Baihui(GV20) and left Qubin(GB7) could increase metabolism of glucose in bilateral Lps and precuneus,the activation of left area in the brain being more significant.②Acupuncture at right Quchi(LI11) and Zusanli(ST36) change metabolism of glucose in left gyrus precentralis,right loblus paracentralis,right gyrus frontalis medialis,both cerebellums and both putarnens.Conclusion All acupoints can change glucose metabolism in cerebral structures related to motor function in the bilateral cerebral hemispheres,different acupoints active different motor areas.The function of acupuncture is a kind of comprehensive regulative process.

A mutant strain L05 was screened from its parent strain Penicillium sp. PT95 by laser irradiation of protoplast. When LOS strain was incubated in Czapek' s agar plates for 20 d, both the sclerotia biomass and carotenoid content accumulated in sclerotia increased significantly compared with that of PT95 strain, and the increase rate reached respectively 98.6% and 28.3% . The carotenoid yield of L05 strain reached 381ug/plate, which was 2.54 times higher than that of PT95. The character of both sclerotia and carotenoid high productivity remained stable after three times of subculture. No sectored colony appeared during subculture.

AlM: To investigate the relationship among carotid atherosclerosis, homocysteine ( Hcys ) and anterior ischmic optic neuropathy( AlON) .METHODS: Sixty-five AlON patients enrolled in AlON group and 70 non - AlON controls enrolled in control group. All the participants in 2 groups were examined by carotid artery color doppler flow imaging to evaluate the incidence of carotid atherosclerosis. Plasma levels of Hcys, vitamin B12 and folate were measured by automatic biochemical analyzer. The incidence of carotid atherosclerosis, plasma levels of Hcys, vitamin B12 and folate were compared statistically between AlON and control group.RESULTS: Fifty - six AlON patients ( 86%) exhibited carotid atherosclerosis, which was found in 43 control subjects ( 61%) . Fifty - nine AlON patients ( 91%) exhibited increased plasma levels of Hcys compared with that in 38 control subjects ( 54%) . Lowered vitamin B12 was found in 37 patients with AlON ( 57%) and in 43 control subjects ( 61%) . Lowered folate was found in 54 AlON patients ( 83%) and in 32 control subjects ( 46%) . The incidence of atherosclerosis in carotid artery ( P =0. 001), mean Hcys level (P=0. 0005) and lowered folate ( P = 0. 0006 ) were different statistically between AlON group and control group. Mean vitamin B12 level was indifferent between AlON group and control group ( P=0. 0722). Logistic regression analysis showed that carotid atherosclerosis was an a risk factor for AlON (OR=1. 312, 95%CI:0. 927~1. 772), whereas elevated Hcys level (OR=2. 378, 95% CI: 1. 479 ~ 3. 821 ) was also shown to be significant risk factor for AlON. CONCLUSlON: Carotid atherosclerosis and elevated Hcys were related with AlON. Reducing above-mentioned risk factors related to thrombus may be crucial to the prevention and cure of AlON.

OBJECTIVE　To develop a method for the determination of theophylline in serum with concomitant use of ofloxacin.METHODS　Theophylline was serum was extracted with chloroform-hexane(7∶3,v/v) after some ammonium sulfate was added.It was re-extracted with NaOH solution (0.1 mol*L-1)and detected with a UV spectrophotometer at 275 nm and 299.5 nm respeitively.RESULTS　The method was linear over the range of 5.0～40.0 mg*L-1(r=0.9997,n=7).The average recovery of methodology was 100.3%(RSD=1.2%),and the extraction recovery from serum was 87.7%(RSD=4.6%).CONCLUSION　This practical method for the determination of serum theophylline can eliminate the interference of ofloxacin and other antibiotics.

By analyzing data from a questionnaire survey on bilingual teaching, we evalueted the results of bilingual teaching for seven-year medical students and the main problems of bilingual teaching and solutions accordingly. An uneven English level on the part of teachers and students and imperfect materials etc. affect the overall results of bilingual teaching. Therefore persistent efforts need to be made in enhancing the teachers' English level, improving teaching methods and compiling proper textbooks so as to genuinely improve the bilingual teaching program.

OBJECTIVETo study whether the dose of controlling antihypertensive drug is reduced by transcutaneous electrical acupoint stimulation (TEAS) and the anesthetics, as well as the control of blood pressure (BP) and heart rate (HR) in endoscopic endonasal surgery with general anesthesia.

METHODSSixty patients for selective endoscopic endonasal surgery with general anesthetics and controlling antihypertension involved were selected and randomized into a TEAS group, a sham-TEAS group, 30 cases in each one. The electric pads were attached to bilateral Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Quchi (LI 11), stimulated with Hans-200 apparatus, 3 to 5 mA, 2 Hz/100 Hz in the TEAS group based on the patients' response to comfort. No electric stimulation was applied to the sham-TEAS group. The general anesthesia started after 30 min intervention and lasted till the end of surgery. The BP and HR were observed and recorded at the end of monitoring in operation room, 10 min after tranquilization (T0), 30 min after intervention (Tj, after induction~of general anestiesa (T2), 30 min after surgery start (T3), 60 min after surgery start (T4) and 30 min after extubation (T5). The doses of vecuronium bromide, propofol and nitroglycerin were recorded statistically in surgery, as well as the operative bleeding volume, the operative time, the resuscitation time and the visual analogue scale (VAS) score after resuscitation.

RESULTSCompared with that at T0, the mean arterial pressure (MAP) at T2, T3, T4 and T5 in the TEAS group and at T3 and T4 in the sham-TEAS group was all reduced, indicating the significant difference (all P < 0.01). MAP at T2 and T5 in the TEAS group was lower than that in the sham-TEAS group (both P < 0.01). Compared, with that at T5, except at T2 in the TEAS group (P<0. 05), HR was not different significantly at the rest time points (all P > 0.05). HR was different at T2 to Ts in the sham-TEAS group statistically (all P < 0.01). The doses of vecuronium bromide, propofol and nitroglycerin, the operative bleeding volume, the operative time, the resuscitation time and VAS after resuscitation were not different significantly between the two groups (all P > 0.05).

CONCLUSIONThe general anesthesia with TEAS and anesthetics involved for controlling antihypertension contributes to the control of BP and HR in the patients in endoscopic endonasal surgery. The impacts are not obvious on the doses of antihypertensive drug, the general anesthetics, the operative bleeding volume, the time of resuscitation and the postoperative analgesia.

The ancient discussion and modern clinical application regarding Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) in acupuncture verses are explored. Acupuncture verses are the summary of clinical experiences of acupuncture scholars in the past dynasties, of which the records on application of Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) mainly focused on nasal, facial and head-eye diseases, which is characterized with overall summarization, brilliant exposition, simple language, and distinctive characteristics. Nowadays, based on the ancient usage, the clinical application about these two acupoints is continuously developing. If the ancient acupuncture verses could be understood thoroughly, the clinical practice could be better guided and its effects could be improved.
