General/family medicine is a newly established major in medical education to meet the demands in general/family doctors. It is a new educational reform subject for medical schools to enhance the teaching for students in general medicine. Pathophysiology is a bridging course for foun-dational medical courses to be connected to clinical courses, and it is also a required course for med-ical students in cultivating students' critical thinking abilities. In military medical schools, there are certain features in the students. It is quite common to find these students have less desired academic foundation, and they come from different areas in the military units and will go back to certain units upon graduation. In the teaching of the course of pathophysiology, it has been proved that the following methods can help promoting the quality of teaching and learning. These methods include adjusting the teaching contents to emphasize the key points, selecting teaching methods to enhance interactions, and utilizing the advantages of internet and multi-media facilities in case discussions. However, there is still a long way to go to find out better ways in adjusting the course contents to the needs of general medicine education and sequencing the foundational courses in the medical courses.

AIM To establish a quantitative analysis of multi-components by single-marker (QAMS) method for the simultaneous content determination of four saikosaponins in Xiaozheng Pellets (Bupleuri Radix,Cyperi Rhi-zoma,Rhei Radix et Rhizoma,etc.).METHODS The analysis of 5％ ammonia-methanol extract of this drug was performed on a Waters Xbridge C18column (250 mm ×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-water flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelengths were set at 210 nm and 254 nm.With saikosaponin a as a internal standard,the relative correction factors of saikosaponins b1,b2 and c were calculated,followed by the determination of their contents.RESULTS Four saikosaponins showed good linear relationships within their own ranges (r ≥ 0.999 5),whose average recoveries were 98.08％-102.94％ with the RSDs of 0.85％-1.82％.The results obtained by QAMS approximated those obtained by external standard method.CONCLUSION This simple,precise and feasible method can be used for the quality control of Xiaozheng Pellets.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

Objective To prepare an active anti-tumor component, compound K (C-K), from saponins in leaves of Panax notoginseng (SLPN) using immobilized β-glucanase. Methods Two entrapments, alginate gel-1 (Alg 1) and alginate gel-2 (Alg 2), were evaluated for their ability to immobilize β-glucanase. The amount and purity of C-K obtained from the transformation process were analyzed by HPLC, and the immobilizing parameters were optimized. Results β-Glucanase can be immobilized and reused with either of the entrapment. However, using AIg 1 resulted in higher enzyme activity than Alg 2. The optimal concentration of the immobilized enzyme was 10%; The optimal crosslinking time was 4-6 h; and the optimal concentration of the crosslinking agent was 6%-7%. Conclusion Immobilized β-glucanase shows sustained enzyme activity, good ethanol tolerance, and was reusable for the preparation of C-K from SLPN.

OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.
