Primary liver adenosquamous carcinoma is a rare kind of liver malignant tumor with very poor prognosis. Clinical data of 5 cases were analyzed retrospectively, four male and one female, whose average age was 60.2 years (50-67 years) old. Adenosquamous carcinoma contains both adenocarcinoma and squamous carcinoma histologically, and squamous carcinoma cells are dominant (>80%). Four cases underwent surgical resection and one received liver transplantation. The postoperative follow-up period ranged from 6 to 35 months and the mean survival time of these cases was about 15 months. Three patients died during the follow-up period. The survival rates 1 and 2 years after operation were 60% and 20%, respectively.

Objective:To screen the best extraction process of four medicinal materials in Simiao Junyi ointment by analgesic ex-periments. Methods:The analgesic experiments were performed by the hot-plate test and writhing test in mice to select the best extrac-tion process of four medicinal materials in Simiao Junyi ointment. Results:According to the results of level consistency check, the data of hot-plate test in mice in different groups had no significant difference, and the pesticide effect of Simiao Junyi ointment prepared by different extraction process was similar. However, the data of writhing test had significant difference. The extraction process of the oint-ment with the best analgesic activity was as follows:pepper and rhizoma corydalis were extracted by SFE-CO2 , myrrha and pseudo-gin-seng was extracted by 95% and 50% ethanol, respectively. Conclusion: The optimal extraction process tested by analgesic experi-ments is scientific, reasonable and feasible, and suitable for the research and development of modern traditional Chinese medicine preparations.

Objective To explore clinical efficacy and mechanisms of medicinal-cake-separated moxibustion treatment for mild-to-moderate ulcerative colitis (UC) of spleen deficiency and dampness type.Methods Totally 60 cases were randomly divided into observation group and control group according to a random digits table, with 30 cases in each group. The control group was inserted into the anus with mesalamine suppository 1 g once a day, while the observation group was given medicinal-cake-separated moxibustion treatment once a day based on the treatment for the control group. Medicinal cake (Aconiti Lateralis Radix Praeparata: Codonopsis Radix: Coptidix Rhizoma: Salviae Miltiorrhizae Radix et Rhizoma: Corydalis Rhizoma: Aucklandiae Radix=3:3:2:2:2:1) was put on the acupoints (Pishu, Zhongwan and Zusanli for the first group, Dachangshu, Tianshu and Shangjuxu for the second group, one group for each time, and 2 groups were used interchangeably). One wormwood cylinder was put on medicinal cake, 5 min each time, 3 doses each time, once a day. The treatment course for all was 8 weeks. The main symptom scores (diarrhea, bellyache, pus and blood stool) and total scores, colonoscopy Baron score and serum CC chemokine ligand 20 (CCL20) expression level were compared between before and after treatment in the two groups. The clinical efficacy was evaluated and the adverse reactions were observed.Results The total effective rate in observation group was 93.33% (28/30) and significantly higher than that of the control group of 76.67% (23/30). After the treatment, the main symptom scores and total scores, colonoscopy Baron score and serum CCL20 expression level were significantly lower than those of pre-treatment in the same one group (P<0.05), which of the observation group were remakably lower than those of the control group (P<0.05); there was one case occured adverse reaction in the observation group and two cases in the control group, with no statistical significance between the two groups (P>0.05).Conclusion Medicinal-cake-separated moxibustion treatment is effective and safe in patients with mild-to-moderate UC of spleen deficiency and dampness type, which effects might be involved in regulating the expression of serum CCL20.

Objective:To explore the degradation effect of gamma-rays radiation sterilization on the effective constituents in Simiao Junyi ointment and study the changes of fingerprint chromatography before and after the sterilization to provide basis for the feasibility of gamma-rays radiation sterilization for Simiao Junyi ointment. Methods:The contents of tetrahydropalmatine and PNS ( Panax Notogin-seng saponins) in Simiao Junyi ointment were determined by HPLC, and the fingerprint chromatography was established. The content changes of tetrahydropalmatine and PNS in Simiao Junyi ointment before and after the gamma-rays radiation sterilization were compared among the same batch and various batches, and the relative retention time and relative peak area in the fingerprint chromatography were also compared. Results:The content of tetrahydropalmatine had no change basically before and after the gamma-rays radiation steriliza-tion(P >0. 05), and there was no change in the total content of PNS (P >0. 05). Comparing the HPLC fingerprint chromatography at 280 nm, the relative retention time had statistically significant change after the gamma-rays radiation sterilization ((P <0.05), while the relative peak area had no statistically significant change(P >0. 05). The number of characteristic peaks reduced by one, namely the C8 characteristic peak disappeared in the pasteurized chromatography, and the areas of C6, C9 and C14 peak decreased significantly, while that of C12 increased. Conclusion:Gamma-rays radiation sterilization have no notable effect on the content of tet-rahydropalmatine and PNS in Simiao Junyi ointment, it can be used for the sterilization of Simiao Junyi ointment.

Background: Mechanical ventilation, particularly one-lung ventilation (OLV), can cause pulmonary dysfunction. This meta-analysis assessed the effects of dexmedetomidine on the pulmonary function of patients receiving OLV. Methods: The Embase, PubMed, MEDLINE, Cochrane Library, ClinicalTrials.gov, and Chinese Clinical Trial Registry databases were systematically searched. The primary outcome was oxygenation index (OI). Other outcomes including the incidence of postoperative complications were assessed. Results: Fourteen randomized controlled trials involving 845 patients were included in this meta-analysis. Dexmedetomidine improved the OI at 30 (mean difference [MD]: 40.49, 95% CI [10.21, 70.78]), 60 (MD: 60.86, 95% CI [35.81, 85.92]), and 90 min (MD: 55, 95% CI [34.89, 75.11]) after OLV and after surgery (MD: 28.98, 95% CI [17.94, 40.0]) and improved lung compliance 90 min after OLV (MD: 3.62, 95% CI [1.7, 5.53]). Additionally, dexmedetomidine reduced the incidence of postoperative pulmonary complications (odds ratio: 0.44, 95% CI [0.24, 0.82]) and length of hospital stay (MD: −0.99, 95% CI [−1.25, −0.73]); decreased tumor necrosis factor-α, interleukin (IL)-6, IL-8, and malondialdehyde levels; and increased superoxide dismutase levels. However, only the results for the OI and IL-6 levels were confirmed by the sensitivity and trial sequential analyses. Conclusions Dexmedetomidine improves oxygenation in patients receiving OLV and may additionally decrease the incidence of postoperative pulmonary complications and shorten the length of hospital stay, which may be related to associated improvements in lung compliance, anti-inflammatory effects, and regulation of oxidative stress reactions. However, robust evidence is required to confirm these conclusions.

OBJECTIVETo evaluate the difference in the clinical therapeutic effects on anal fissure at Ⅰ and Ⅱ stages between the acupoint catgut embedding therapy and western medication.

METHODSSixty patients of anal fissure at Ⅰ and Ⅱ stages were randomized into an embedding therapy group and a western medication group, 30 cases in each one. In the embedding therapy group, the acupoint catgut embedding therapy was applied at bilateral Tianshu (ST 25), Changqiang (GV 1), bilateral Chengshan (BL 57) and Tigangxue (Extra), once a week. In the western medication group, the external inunctum on the wound was given with 0.2% nitroglycerin ointment, once every morning and evening a day. The treatment lasted for 4 weeks continuously in the two groups. The follow-up visit was done for 3 months after treatment. The visual analogue scale (VAS) and anal pain duration were observed and recorded before treatment and on the 3rd day and the 7th day of treatment separately. The clinical therapeutic effects were compared between the two groups.

RESULTSAfter treatment, on the 3rd day and the 7th day of treatment, VAS score and anal pain duration were all reduced significantly as compared with those before treatment in the patients of the two groups (all<0.01). The differences in the embedding therapy gruop were better than those in the western medication group before and after treatment (<0.01,<0.05). In the 2nd and 4th weeks after treatment, the clinical therapeutic effects in the embedding therapy group were better than those in the western medication group (both<0.05). In 3-month follow-up, the recurrent case in the embedding therapy group was one, and the recurrent case in the western medication group was six.

CONCLUSIONSThe acupoint catgut embedding therapy is safe and effective in the treatment of anal fissure at Ⅰ and Ⅱ stages and its recurrent case is lower as compared with the treatment of western medication.
