Fu's subcutaneous needling (FSN) is a modern approach developed from traditional Chinese acupuncture. It could give some stimulation in the subcutaneous region that has a quick and long-lasting effect on soft tissue injuries and some of the internal medicine diseases. It is a safe approach without adverse reaction. Through analysis of the features and possible mechanism of FSN, it is believed that research on mechanism of FSN is beneficial to the development of modern medicine, especially to pain management.

Objective To undemtand the rhythm of urinary iodine level of children aged 8-10 in Chongqing city.Methods In April 2008,using the stratified random sampling method,we sampled 60 children aged 8-10 in a lodging primary school in Chongqing(20 per age group,half male and half female),the urine samples were collected in the morning and at 10:00,12:30,16:00,iodine in urine was detected by method of Ce and arsenic catalytic speetrophotometry(WS/T 107-2006).The difference of the urinary iodine level was compared by age,sex and time of day.Results The median urinary iodine of 60 children was 265.07μg/L on the overall.Irrespective of the stratification factors,excluding morning urinary iodine(366.75μg/L)and urinary iodine at 10:00(338.30 μg/L),the urinary iodine between 12:30(235.15μg/L)and 16:00(251.50μg/L)was not significant(all P>0.05),statistically significant differences(all P<0.05)were found between any two.The urinary iodine of 8-year-old group at different times of the day was significantly different(all P<0.05),except between morning urinary iodine (298.90 μg/L)and at 10:00,16:00(279.00,286.59 μg/L),between urinary iodine at 10:00 and 16:00(all P>0.05).The 9-year-old group's urinary iodine were not significantly different between morning urine(366.15μg/L)and 10:00(368.10 μg/L),and between 12:30(244.00 μg/L)and 16:00(186.30 μg/L,all P>0.05),significant differences were faund at other times of the day(all P<0.05).The 10-year-old group of urinary iodine changed very little before 12:30 (382.85,449.60,337.00 μg/L, all P > 0.05 ), followed by rapid decline to 16: 00 (269.35 μg/L), and compared with the morning urine and 10:00, there was significant difference(all P < 0.05).Regardless boys or girls, the urinary iodine at different times qf the day was significantly different (all P < 0.05),except between morning urinary iodine(337.32,309.28 μg/L) and at 10:00(316.15,288.27 μg/L), between urinary iodine at 12:30(251.18,211.45 μg/L) and 16:00(235.02,211.45 μg/L, all P > 0.05). Conclusions The change of urinary iodine level in children aged 8 - 10 was not obvious before noon, changes can be seen in the afternoon.Urinary iodine level before 10:00 is indicative.

Linear solvation energy relationships are of a great value in investigating quantitative structure-retention relationship and quantitative structure-activity relationship, and predicting chromatographic retention indices of drugs. Several quantitative relationships in different in vitro biomembrane-mimetic models between retention factors and molecular descriptors have been established successfully and used to clarify drug-membrane interaction mechanisms. Quantitative structure-activity relationships also have been established to predict drug intestinal absorption, permeation of skin and blood-brain barrier. This review focused on the significance and widely application of linear solvation energy relationships in quantitative assessment for mechanisms of partitioning and absorption of drugs. The discrepancy and limits of linear solvation energy relationships were also discussed, which gives us a better insight into investigation of partitioning and absorption of drugs.

Six crystalline components were isolated from the lipophilic fraction of Artemisia annua L. They have been identified as four sesquiterpenes, one flavonol and one coumarin. Qinghaosu I and III are new sesquiterpenes. Five main constituents, camphene, iso-artemisia ketone, 1-camphor, β-carophyllene, and β-pinene were identified from the volatile oil of this herb.

Objective To investigate the renal pelvic pressure(RPP) during minimally invasivepereutaneous nephrolithotomy(MPCNL),and inspect its influence to postoperative fever. MethodsThe RPP was measured by baroeeptor,and these data about pressure and postoperative fever wereevaluated statistically. Results The mean RPP was 14.72 mm Hg,the mean accumulative time of RPP≥30 mm Hg was 116.06 s. Fifteen cases(18. 75%)had a postoperative fever. Logistical analysissuggested that postoperative fever did not correlate to sex(P=0.195),age(P=0.641),urinary tractinfection (P=0.663),white blood cell≥10 × 109/L in blood routine examination postoperatively (P=0.751),once an occurrence of RPP≥40 mm Hg(P=0.662),while infection calculi (P=0.000),percutaneous tract size(P=0.029),mean RPP(P=0.036) ,mean RPP≥20 mm Hg(P=0.013),accumulative time of RPP≥30 mm Hg(P=0.010) and RPP≥30 mm Hg longer than 50 s(P=0.024)contributed to postoperative fever. Conclusions Renal pelvic pressure generally remains lower than alevel to back flow (30 mm Hg) during MPCNL. A transient renal pelvic pressure≥30 mm Hg don'tcountribute to postoperative fever,while a temporary high pressure status(50 s)would had an accumulated effect which means an enough back flow to bring a fever.

One hundred and seventy-two strains of endophytic fungi were isolated from Taxus mairei,Cephalotaxus fortunei and Torreya grandis cv.merrillia.The result of the antifungal assay shows that ninety strains of the fungi have antagonism against one or more botanical pathogenic fungi,such as Neurospora sp.,Trichoderma sp.,Fusarium sp.etc.The percentage of antifungal strains to tested strains are as follows:40% Cephalotaxus fortunei,54.2% Taxus mairei,57.1% Torreya grandis cv.merrillia.Thirty-five strains have high antifungal activities,and their inhibition zone diameter is at least 15mm.The active endophytic fungi were identified as 18 genera,most of which belong to Paecilomyces and Fusarium etc.

Objective To study the bioavailability and bioequivalence of erythromycin ethylsuccinate granules in healthy male volunteers.Methods In a randomized two-period crossover study,20 healthy male volunteers received single 500 mg test and reference formulations of erythromyein ethylsuccinate granules.The plasma concentrations of erythromycin were assayed by microbiological method.Results The parameters of test and reference preparations were as follows:T_(max)(0.86?0.22)and (0.80?0.13)h,C_(max)(2.13?0.64)and(2.16?0.61)mg/L,t_(1/2)(2.04?0.2)and(1.97?0.4)h,AUC_(0-t)(4.96?1.73)and(4.63?1.52)mg?h/L,respectively.There was no significant difference between the two preparations.The rela- tive bioavailahility of the test granules was(109.1?22.8)%.Conclusions The two preparations of erythromycin ethylsucci- nate granules are bioequivalent.
