Case discussion is an effective approach,which combines basic theory with clinical medicine.It can evoke students' interest and cultivate their creative thinking capacity.Moreover,it can improve teachers' general ability in teaching pathophysiolo- gy.In this article,we discuss the application of case discussion in pathophysiology teaching.

Objective To establish a method predicting CTL epitopes of antigens in Yersinia pestis,which provides an effective research plan for epitnmics in Yersinia pestis.Methods CTL epitopes were predicted by nHLAPred.BIMAS and SYFPEITHI.Results CTL epitopes of LcrV antigen were detected as V8-16 NPQHFIEDL,V311-319 KYDSVMQRL and V258-264 SYNKDNNEL.Conclusions Prediction of CTL epitope can be used to make epitope mapping because of its hiigh accuracy.It may provide a reference for the epitope mapping plan.

Objective To observe the effect of nitroglycerin(NTG) on pulse wave velocity(PWV) in patients with hypertension(HTN).Methods36 volunteers,mean age 48.1±10.2 years,were divided into HTN group and non-hypertension(NHTN) group according to whether he or she had hypertension or not.The baseline PWV and PWV at 5th minute and 10th minute after sublingual NTG were detected.PWVs of the two groups were compared.ResultsThe basal PWV in HTN group was higher than that in NHTN group.PWV was reduced significantly after NTG were given sublingually 5 minutes or 10 minutes compared with baseline condition(both P<0.01).PWV 10 minutes after sublingual NTG raised a little compared with that after 5 minutes(P<0.01).PWVs 5 minutes or 10 minutes after sublingual NTG in HTN group were higher than those in NHTN group(both P<0.05).ConclusionNTG can reduce PWV in patients with HTN.

The self-designed experimental teaching method is introduced in detail in this paper,including the preparative work before class,discussion of experimental designing proposal,and accomplishment of specific experiment and so on.The teaching method innovations on pathophysiology experiment are very helpful to cultivate the students' ability to solve practical problem and lay the foundation to cultivate talented medical science personal.

Ovarian endometrioma is a common form of endometriosis, which may cause infertility, dysmenorrhea and pelvic pain in women of reproductive age. Although surgery is the treatment of choice for endometriomas, recurrence poses a formidable frustration. This study investigated potential risk factors of endometriomas recurrence, aiming to better understand its pathogenesis. A total of 307 patients with endometriomas were followed up for an average of 28.6 months and the 1-, 2- and 3-year cumulative recurrence rate was 9.5%, 21.9%, and 29.2%, respectively. Twenty-one potential risk factors for endometriomas recurrence were evaluated using Cox's proportional hazards models. Total revised American Fertility Society (rAFS) score was significantly associated with higher recurrence (OR=1.858, 95% CI=1.122-3.075, P=0.016), as well as younger age at surgery (OR=0.953, 95% CI=0.915-0.992, P=0.020). Semiradical surgical treatment was defined as surgical removal of cyst plus hysterectomy with preservation of bilateral or unilateral ovary, and was a significant factor that was associated with lower recurrence than the conservative surgery (OR=0.318, 95% CI=0.107-0.951, P=0.040). Postoperative pregnancy was favorable factors for disease recurrence (OR=0.217, 95% CI=0.102-0.460, P=0.000). The results suggest that endometrioma recurrence is inversely associated with age at surgery and postoperative pregnancy, and may correlate with total rAFS score and conservative surgery method.

Objective To explore the role and clinical significance of interleukin-6(IL-6) in children with bronchial asthma.Methods Sera were collected from 29 cases with asthmatic attacks,32 asthmatic children who in stable conditions,and 20 health children.Serum IL-6 concentrations were measured by radioimmunoassay(RIA).Results 1.Asthmatic children appeared significantly higher levels of serum IL-6 during asthmatic attacks as compared to those in stable conditions and healthy ones respectively(P3 years old had significantly higher serum IL6 concentrations than ≤3 years old children in remission.Conclusion IL-6 may participate pathogenesis of asthma,and it may play different biological roles during asthmatic attacksas or stable conditions.

In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.

METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.

RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).

CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

Photosynthetic and growth characteristics of Angelica dahurica were studied in order to clarity the relations of photosynthesis, growth and root dry weight, and provide a theoretical basis for its cultivation. Photosynthesis and growth indexes were meas- ured every 25 days. The contents of chlorophyll a, b, a + b, soluble protein and the activities of Hill reaction, Ca(2+)-ATPase, Mg(2+)-ATPase had an increasing trend; They had the highest value in leaf high-speed growth period. Then, they were decreased in root high- speed growth period. The root dry weight showed negative corelation with photosynthetic characteristics indexes except stomatal con- ductance, however, the negative corelation only from net photosynthetic rate and Ca(2+)-ATPase were significant. The vegetative growth period of spring sowing A. dahuricia was divided into three phases: seedling period, leaf high-speed growth period and root high-speed growth period. The root dry weight showed a significantly positive corelation with the root diameter, leaf dry weight, shoot dry weight, aboveground dry weight. There was the competitive relation between aboveground and underground, so underground growth could be es- timated from leaf area and shoot dimeter.
