OBJECTIVE:To discuss the influence of Shanghai Guiding Principles of Clinical Use of Antibiotics Implementing Rules(Trial)(named Implementing Rules for short) on prophylactic use of drugs in patients underwent general surgery operation.METHODS:In retrospective study,inpatients of general surgery department in our hospital from Sep.2006 to Feb.2008 were divided into 3 groups(Group 1:6 months before Implementing Rules issued;Group 2:0～6 months after Implementing Rules issued;Group 3:7～12 months after Implementing Rules issued).The utilization of antibiotics was analyzed as well as its rationality.RESULTS:A total of 1 308 cases were enrolled.The utilization frequency of antibiotics was 3 463.Less than half of cases met the indication of antibiotics while the rate of drug sensitivity test was 1.2%.The treatment courses of 3 groups were(3.4?4.3) d,(3.3?2.9) d and(3.1?3.0) d.The proportions of rational drug use were 36.5%,35.1% and 40.7%.But the selection of antibiotics,drug combination and ADR report were not significantly improved.CONCLUSION:The issue of Implementing Rules has promoted the rational use of antibiotics in general surgery department.Further training and monitoring are needed.

?AlM:To compare the effect of iris location guided sub-bowman keratomileusis ( SBK ) and iris location guided thin - flap laser in situ keratomileusis ( LASlK ) for extremely high myopia treatment.
?METHODS:lris location guided SBK was performed in 64 eyes of 32 patients with extremely high myopia and 42 eyes of 84 patients were received iris location guided thin-flap LASlK. All the patients’ spherical refraction was-9. 00D ~ - 11. 00D and the age was 22 ~ 35 years. Uncorrected visual acuity ( UCVA) , refraction, split-lamp examination, topography examination, central corneal stroma thickness, thickness of central corneal flap, thickness of peripheral corneal flap and complication was examined in these patients and follow-up was 6mo.
?RESULTS:At 6mo after surgery, 93. 8% of the patients received iris location guided SBK and 92. 9% received iris location guided thin-flap LASlK achieved a UCVA better than 20/20. There was no significant difference between two groups. Refraction between ±0. 5D was 89. 1% of SBK group and 84. 5% of LASlK group. There was no significant difference. Corneal rear surface height of SBK was 0. 046±0. 012μm and LASlK was 0. 056±0. 015μm. Thickness of corneal stroma after surgery was 328. 6±14. 7μm in SBK group, while it was 301. 2±21. 6μm in LASlK group and there was significant difference ( t =3. 127, P=0. 001). BUT was 11. 38±4. 02s and 17. 81±4. 89s in SBK and LASlK group respectively, with no statistical difference. There was no serious complication in two groups.?CONCLUTlON:Both iris location guided SBK and thin-flap LASlK are effective for extremely high myopia, but SBK is safer and more predictive than thin-flap LASlK.

OBJECTIVETo observe the effect of Tai Ji Quan (TJQ) training on strength and function of lower limbs in the aged.

METHODSSixty senile subjects were recruited and assigned to the TJQ group and the control group (imparting health knowledge)by random digit table. Patients in the TJQ group received 24-style TJQ training for 18 months (60 min each time, 5 times per week), while those in the control group were imparted with sarcopenia related causes, pathogeneses, prevention and control measures. The maximum isometric strength of bilateral iliopsoas, quadriceps femoris, tibialis anterior muscle, hamstrings; the time for 5 sitting-up tests and Time Up and Go Test (TUGT), one-leg standing time with closed eyes test; and the score of Berg balance scale were compared between the two groups.

RESULTSCompared with before treatment, muscle strength increased in the TJQ group with an average increased capacity (rate) as follows, bilateral iliopsoas 5.5 kg (16.9%), quadriceps femoris 5.5 kg (26.2%), and tibialis anterior muscle 8.5 kg (36.2%) (all P < 0.05). The time for TUGT and 5 sitting-up tests was shortened by 1.3 s (16.7%) and 0.9 s (14.5%) respectively in the TJQ group. The time for one-leg standing time with closed eyes test was increased by 8.4 s (left) and 9.1 s (right) respectively. The score of Berg balance scale increased by 4.3% (P < 0.05). Compared with the control group, bilateral quadriceps femoris and tibialis anterior muscle strength increased significantly (P < 0.01); the time for TUGT and 5 sitting-up tests, the time for one-leg standing time with closed eyes test, scores of Berg balance scale were all improved in the TJQ group after intervention (P < 0.05).

CONCLUSIONTJQ training could improve strength of iliopsoas, quadriceps femoris, tibialis anterior muscle in the aged, elevate their balance and locomotor activities, and possibly prevent and treat sarcopenia.

A potentiometric immunoelectrode with non-labeled anticancer antigen CA 15-3 antibody used for determinating CA15-3 was reported. firstly, the anti-CA15-3 antibody was immobilized on the surface of polyvinyl chloride-bovine serum albumin membrane, which was activated previously. Secondly, CA15-3 was added on the surface of the antibody membrane to form the antigen-antibody complex. Lastly, the complex membrane was used to assemble an immunoelectrode with an Ag-AgCl inner electrode. The potential of the complex membrane was measured with a pH meter. The response was linear over the range of 15～240　U／mL with a correlation coefficient of 0.9998. Other common antigens in human serum did not interfere with the determination of CA15-3. The mechanism of potential response was explored.

Objective To explore the clinical efficacy and safety of progesterone combined with Tiaojinghuoxue tablets in treating amenorrhea induced by antipsychotic drugs. Methods Total 100 patients were randomly divided into treatment group treated by progesterone combined with Tiaojinghuoxue tablets and progesterone group. The index including prolactin (PRL), luteinizing hormone (LH), estradiol (E2), endometrial thickness were measured before and after treatment in both groups . Also the clinical efficacy of the twogroups were compared. Results PRL, LH, E2, endometrial thickness and the recovery of menstrual flow rates in combination group were all better than the progesterone group, (P<0.05 or P<0.01). Cure rate in the combined group was 54.00%and the control group was 74.00%(P<0.05). Total effective rate of combined group was 90.00%and the control group was 80.00%(P>0.05). The rate of adverse reactions in combined group was 40.00%, less than 22.00%in progesterone group, (P<0.05). Conclusion The efficacy of progesterone combined withTiaojinghuoxue tablets is better than single progesterone treatment and have fewer adverse reactions in therpy antipsychotics drug induced amenorrhea.

Objective To investigate the clinical significance of peripheral blood parameters including immature reticulocyte fraction (IRF) in monitoring the hematopoietic recovery of patients with acute myeloid leukemia aftcr receiving consolidation chemotherapy with high dose cytarabine (HDAC).Methods The peripheral blood parameters,including absolute neutrophil (ANC) and platelet (Plt) counts as well as IRF,were measured by Sysmex XE-2100 automated hematology analyzer before and after consolidation chemotherapy with HDAC in 30 patients with acute myeloid leukemia.These peripheral blood parameters were further statistically analyzed and compared.Results Following consolidation chemotherapy,the median time to recovery for ANC,Plt and IRF was (9.2±2.5) days,(11.3±3.7) days and (5.0±2.6) days,respectively.In comparison with ANC and Plt recovery,IRF showed significantly early recovery (P ＜ 0.05).Additionally,ANC raised preceding Plt recovery (P ＜ 0.05).However,the median recovery time of ANC,Plt and IRF showed little difference among these patients further subgrouped according to FAB and risk based classification (P ＞ 0.05).Conclusion IRF is an early indicator for the hematopoietic recovery of patients with acute myeloid leukemia following consolidation chemotherapy with HDAC,which could provide important clinical information to evaluate therapeutic efficacy.

Objective To study the survival, migration and distribution of allogeneic marrow stromal cells (MSCs) which were marked with fluorescence agent Hoechst 33342 in vitro and then transplanted into the mice with acute radiation injury, and to explore the hematopoietic reconstitution in allogeneic MSCs transplantation. Methods The bone marrow of murine femoral bone was washed out with DMEM, the cell suspension was gathered and centrifuged twice, and then the MSCs were cultured in vitro, marked with Hoechst 33342 at final concentration of 10?g/ml. 30 minutes later, the MSCs were gathered and transplanted into radiation injured mice via intravenous injection. Each mouse was injected with 2?105 MSCs. The distribution of marked MSCs was observed in heart, liver, spleen, lung and kidney of radiation injured mice at time points of 1w, 2w and 3w after MSCs transplantation. Results After being marked with Hoechst 33342, the nuclei of MSCs were in bright blue color. All mice of MSCs-transplant-group survived until execution, but three mice of Non-MSCs-transplant-group died during three weeks. Only a few marked MSCs were found in heart, liver, lung and kidney in the frozen section at each time point, but a large number of marked MSCs were found on the surface of spleen, and colonies were formed two weeks after introduction of MSCs. Conclusions Transplanted MSCs can not only survive in the irradiation injured mice, but also specifically migrate to the injured site, to participate in the reconstitution of hematopoiesis after acute radiation injury.

AIM: To investigate the effectiveness of dosing technology and excipient application on solid drug's moisture-proof property and to provide a method improving the solid drug's moisture-proof property. METHODS: Based on the analysis of the moisture absorbing process and the absorbing mechanics,a new concept "active moisture absorbance site"(AMAS) was defined and mathematic model was constituted.Two constants as: initial AMAS concentration C_0,moisture resistance coemcient K,were proposed to indicate the drugs moisture-proof ability. The CI WU JIA extracts and SHUANG HUANG LIAN extracts were used to conduct experiments, which were designed to investigate the improvement of the drug's moisture resistance ability when varying the AMAS's concentration and/or its space distribution. RESULTS: Reducing the amount of moisture absorbance excipients in each dosage of solid drug can lower the drug's moisture absorbance ability,and applying a thin film coating material outside the drug can also slow the drug's moisture absorbance rate. CONCLUSION: The proposed mathematic model is useful for finding a way to improve the drug's moisture resistance;experimental data shows that the drug's moisture-proof property would be improved by reducing the amount of moisture absorbance excipient in each dosage and improving the moisture distribution resistance through a certain dosing technology,such as film coating technology.
