ObjectiveTo analyze and sum up the medication rule and the core prescription of Professor LIU Minru in the treatment of polycystic ovary syndrome （intracellular lipid membrane congestion syndrome）and explore the effect mechanism underlying the medication. MethodTwo platforms were used to carry out data mining to analyze the characteristics and rules of Professor LIU's prescriptions for the treatment of this disease. Network pharmacology was used to further clarify active ingredients in the core prescription，and a traditional Chinese medicine-active ingredient-target network was constructed，with the potential mechanism of action analyzed. ResultA total of 321 prescriptions were included in the medical records，involving 178 Chinese medicinals and 28 kinds of formula granules.The Chinese medicinals mainly act on the liver and kidney meridians， whose main tastes were sweetness，pungency，and bitterness and properties were mainly warm，mild，and slightly cold.Commonly used medicine pairs include Dioscoreae Rhizoma-Rehmanniae Radix Praeparata，Chuanxiong Rhizoma-Angelicae Sinensis Radix，Bupleuri Radix-Aurantii Fructus，and Gleditsiae Spina-Curcumae Rhizoma.The commonly used formulas are Xuefu Zhuyutang，Siwugang，Yangjing Zhongyutang，etc. The core prescription is composed of 12 Chinese medicinals such as angelica，white peony，saponaria thorn，and epimedium，containing 74 active ingredients，including quercetin，luteolin，kaempferol，fisetin，and β-sitosterol.A total of 37 key targets were found，involving phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt），mitogen-activated protein kinase （MAPK），Janus protein tyrosine kinase （JAK）/signal transduction and activator of transcription （STAT），and other signaling pathways. ConclusionThe pathogenesis of this disease is complex.Professor LIU adheres to the pathogenesis of "kidney deficiency as the root cause，and phlegm retention as the symptom". Under the guidance of the academic ideology of "kidney Qi as the root，and protecting Yin as the foundation" and "nurturing Yin to support Yang"，she takes into account Yin and Yang in kidney tonic，replenishes and consolidates the essence and blood，and relieves manifestations by dissipating mass， activating blood， and regulating Qi. She has a rigorous thinking in formulating prescriptions. The core prescription has the characteristics of comprehensive regulation by multiple components at multiple targets in multiple pathways.

Objective To observe the effects of different anesthetic techniques on T-lymphocyte subsets in patients with cardia cancer. Methods Thirty-two patients undergoing elective radical operation for cardia cancer who had been average assigned into two groups by random digits table, group Ⅰ :general anesthesia;group Ⅱ :epidural anesthesia combined with general anesthesia (16 cases in each group).Peripheral blood T-lymphocyte subsets were measured before induction, after anesthesia, end of operation, 1d,3 d after operation. Results CD3,CD4,CD8 and CD4/CD8 all decreased in two groups after anesthesia,end of operation and 1 d after operation than before induction (P < 0.05). The index almost returned to the baseline values at 3 d after operation in group Ⅱ [ (60.75 ± 4.22 )%, (39.65 ± 3.64)%, (25.90 ± 1.17 )%,1.57 ±0.15](P >0.05),while in group Ⅰ still lower [(55.83 ±5.20)%, (35.15 ±5.65)%, (23.00 ±1.03 )%, 1.47 ± 0.35 ](P< 0.05 ). The two groups ontrast had significant deviation at 3 d after operation (P<0.05). Conclusion Epidural anesthesia combined with general anesthesia can reduce depression of Tlymphocyte subsets induced by surgical trauma and anesthesia.

It obtains some extent fadeaway of icterus which has a low rebound,reduce TBiL(17.83±3.65)% and there be no statistics difference of rebound.It lowers the blood ammonia level and improves the hepatic encephalopathy and brain oedema.It absorbs cytokine IL-8.Atthough it has some extent effect to albunfin,blood paltelet,haemoglobin.Conclusion HA330-Ⅱ microporous resin plasma adsorption has good application value in the treatment of chronic severe hepatitis B.It is a new treatment choice of severe hepatitis.

Objective To compare the different types of physical artificial liver support system(ALSS) applied in the treatment of patients with early stage of chronic severe hepatitis in order to evaluate the therapeutic effect and look for the most effective one.Methods One hundred and twenty patients of chronic severe hepatitis B in early stage were randomly divided into 4 groups(each n=30).The patients in group 1 were treated by 3 000 ml plasma exchange;in group 2,by 2 000 ml plasma exchange combined with plasma adsorption for 2 hours;in group 3,only by plasma adsorption for 3 hours and in group 4,by molecular adsorbent re-circulating system(MARS).The observation time lasted for 2 weeks and the therapy twice a week,the interval between two times of treatment being 2-3 days.The improvement of symptoms,the fade away and rebound of icterus,the changes of albumin and prothrombin activity(PTA),side effects(anaphylaxis,hepatic encephalopathy,edema of conjunctiva,burp,fluid and electrolyte balance failure,changes of blood routine test and ammonia level,etc) were compared before and after the treatment.Results The symptoms of 27 cases in group 1 were improved,the rate of decrease of total bilirubin(TBil) of group 1 was 51.8% and the range of icterus rebound was 14.4% to 46.7% with comparatively more side effects.The symptoms of 24 cases of group 2 were improved,the rate of decrease of TBil in group 2 was 62.2% and the range of icterus rebound was 2.8% to 28.5% with comparatively less side effects.The symptoms of 16 cases of group 3 were improved,the rate of decrease of TBil in group 3 was 38.8% and the range of icterus rebound was 2.8% to 6.8% with less side effects.The symptoms of 26 cases of group 4 were improved,the rate of decrease of TBil in group 4 was 60.1% and the range of icterus rebound was 7.8% to 27.4% with comparatively more side effects,moreover the cost was higher than that in the other groups.Conclusion The method of reduced plasma exchange combined with plasma adsorption with macroporous resin used to cure chronic severe hepatitis at early stage has the characteristic of good effects for the fade away of icterus,little rebound of icterus and side effects.It is the reasonable method of artificial liver to cure the early stage of chronic severe hepatitis.

Objective To study the shape differences of upper epidermal cells in leaves of medicinal plants of Swertia L. and establish the new method for identifying them. Methods The epidermis were mounted in ordinary technique, and then scanned and binarized through HPIAS-1000 image analytic system. The waveness of the anticlinal walls (SFC) and the ratio of the Ferets diameter (SLF) of upper epidermal cells were detected. The leaf epidermal cells of 21 kinds of raw materials in 12 plants of Swertia L. from various regions were examined. Results The precision and reproducibility of software system were good, and the shape characters of the upper epidermal cells of the middle lamina in the third node arising from ground are the stablest inside the same species by the magnification 20?10 under microscope. The SFC and SLF of the upper epidermal cells of the same species of plants are relatively constant, conversely that of different species of plants are obviously different and distinguishable from each other. Conclusion The proposed method is a useful technique for identifying traditional Chinese medicinal materials originated from herbs and leaves of plants. HPIAS-1000 is simple, rapid, accurate, and practical for shape analysis of upper epidermal cells of plant leaf.
