OBJECTIVETo compare the clinical therapeutic effects between ozone and triamcinolone acetonide for the treatment of mild meniscal injury.

METHODSFrom January 2008 to December 2012, 119 patients with meniscal injury diagnosed as type I or II by MRI were divided into three groups. In the triamcinolone acetonide (A) group, there were 38 males and 2 females, with an average age of (25.34 +/- 6.34) years old, ranging from 18 to 48 years old; 36 patients had single knee injuries, 4 patients had double knee injuries and 44 knees with joint effusion. In the ozone (B) group,there were 37 males and 2 females, with an average age of (26.98 +/- 7.20) years old, ranging from 19 to 50 years old; 33 patients had single knee injuries, 6 patiens had double knees injuries and 40 knees with joint effusion. In the combination of ozone and triamcinolone acetonide (C) group, there were 37 males and 3 females,with an average age of (26.44 +/- 6.38) years old, ranging from 18 to 47 years old; 33 patients had single knee injuries, 7 patients had double knees injuries and 39 knees with joint effusion. The patients were treated with injection of 3 mg triamcinolone acetonide alone, 30 ml (30 microg/ml) ozone alone, or both two drugs respectively in knee joint cavity. All the treatment methods were carried out weekly and 4 times injections were required for a treatment course. Knee joint function was evaluated by Lysholm scale and knee joint effusion was examined by MRI before and after treatment.

RESULTSThe scale of knee joint function was 35.68 +/- 4.15 and 65.55 +/- 7.66 in group A, 36.35 +/- 6.83 and 74.39 +/- 8.47 in group B, 36.62 +/- 6.03 and 95.47 +/- 4.78 in group C before and after treatment. Compared with that before treatment, the total scale of knee joint function improved after treatment in every group. The total scale of group C was better than that of the other groups after the treatment,but there was no significant difference between group A and group B. The effective rate of these drugson joint effusion was 68.18% in group A, 62.5% in group B and 87.18% in group C. The effect of co-injection on joint effusion in group C was significantly better than that of triamcinolone acetonide or ozone alone, but the difference between group A and group B was not significant.

CONCLUSIONOzone and triamcinolone acetonide are effective in the treatment of mild meniscal injury, which can relieve symptoms and promote the recovery of joint function. Campared with the single injection, the combination of ozone and triamcinolone acetonide is better.

OBJECTIVETo explore the effect of acupuncture-anesthetic composite anesthesia (AACA) on the incidence of postoperative cognitive dysfunction (POCD) and changes of TNF-alpha, IL-1beta, and IL-6 in elderly patients.

METHODSTotally 83 patients undergoing surgical resection of gastrointestinal tumor were randomly assigned to the simple anesthesia group (A group, 41 cases) and the AACA group (B group, 42 cases). Patients in Group A received endotracheal general anesthesia. Those in Group B were induced by acupuncture anesthesia for 30 min by needling at Baihui (DU20), Neiguan (PC6), Zusanli (ST36). The electro-acupuncture (EA) apparatus was connected after arrival of qi, with the wave pattern of density 2/100 Hz. The stimulus intensity was set by patients' tolerance, with the peak current of 5 mA. Then the endotracheal general anesthesia was performed and the EA lasted till the end of the surgery. The cognitive function of all patients was assessed before operation and at day 3 after operation using mini-mental state examination (MMSE). POCD was confirmed if with one or more decreased stand- ard. The peripheral venous blood was collected before anesthesia induction (TO), immediately at the end of surgery (T1), 24 h after operation (T2), and 48 h after operation (T3), and serum concentrations of IL-1beta, IL-6, and TNF-alpha were correspondingly measured using ELISA.

RESULTSThe postoperative anesthesia awakening time was shorter in Group B than in Group A [(20.37 +/- 6.09) min vs (29.24 +/- 7.48) min, P < 0.05]. The remifentanil dose used during the operation was less in Group B than in Group A (P < 0.05). The incidence of POCD at day 3 was lower in Group B than in Group A [10/41 (23.8%) vs 15/42 (36.5%), P < 0.05]. The concentrations of IL-1beta, IL-6, and TNF-alpha at T1-T3 were higher than those at TO in the two groups (P < 0.05). The increment of TNF-alpha and IL-1beta was less in Group B than in Group A (P < 0.05). CONCLUSION AACA could reduce the incidence of POCD and inhibit postoperative release of TNF-alpha, IL-1beta, and IL-6 in elderly patients undergoing colorectal cancer resection.

OBJECTIVETo observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs.

METHODSOne hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation.

RESULTSThe incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05).

CONCLUSIONThe general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

Objective To study the effects on berberine hydrochloride on the mitochondria membrane potential and free intracellular calcium of HaCaT cells, and elucidate the mechanism of action of berberine on keratinocytes. Methods Rhodamine-123 fluorescence (very sensitive to mitochondria membrane potential) and Fluo-3/AM fluorescence (suitabe to detect free intracellular calcium in single HaCaT cell) were measured by laser scanning confocal technique. Results Fluo-3/AM fluorescence intensity of HaCaT cells was persistently increased after treating with berberine at concentrations of 5 ? 10-5M, 2.5 ? 10-5M and 1.25 ? 10-5M, and significant differences were observed as compared with the PBS control. The intensity of rhodamine-123 fluorescence in HaCaT cells was decreased immediately when exposed to berberine, with significant difference from that of the PBS control. Conclusions It is suggested that berberine could increase free intracellular calcium and decrease mitochondria membrane potential of HaCaT cells, induce overload of intracellular calcium, influence energy metabolism, and then inhibit the proliferation of keratinocytes.

OBJECTIVETo study the status of infection and type-specific distribution on human papillomavirus (HPV) in the urban areas of Shenyang city, China and to provide data for vaccine introduction.

METHODSA list of 1000 women aged 15-59 years were obtained randomly from the local population, and a questionnairey was filled in. Samples of cervical cell were obtained from 702 women who had had sexual experience and were not pregnant during the study was carried on. HPV type was detected using a GP5+/6+ -based PCR, liquid-based cytology, VIA, VILI and electronic coloscopy were used for screening on cervical cancer.

RESULTSThe prevalence of any HPV type was 17.0% among the 702 women who had been enrolled in this study, 64.1% in women with abnormal cytology, 11.1% in women with normal cytology and the difference was significant. The prevalence of high-risk HPV type was 11.9% and the low-risk type was 6.5%. The prevalence of either high-risk or low-risk HPV type was significantly higher in women with abnormal cytology than those with normal cytology. There were a total number of 32 HPV types identified and the most common HPV types were 16 (3.4%), 52 (2.4%) and 58 (1.9%). The prevalence rates of either high-risk or low-risk HPV type were not statistically different among different age-groups with P>0.05. HPV types with high risk were predominantly distributed in the groups below 45 years old and the difference was significant with P < 0.05. There was no significant difference between high-risk and low-risk types above 45 years old.

CONCLUSIONThe prevalence of HPV in women with abnormal cytology was statistically higher than those with normal cytology. The most common HPV types in this population were 16, 52 and 58, and the validity of present vaccines was not good enough for cervical cancer prevention in this local area.

The discovery of high performance leading antidiabetic compounds containing sulfonamide and 4-aminophenylacetic acid moieties is reported. This was achieved by the synthesis of 6 intermediates and subsequently 20 target molecules using 4-aminophenylacetic acid as the starting materials, and through a few synthetic routes aided by multi-step reactions including sulfonylation of amino group, deacylation of amides and esterification of carboxyl group, as well as acylation of amino group. The chemical structures of the twenty-four new compounds were determined using 1H NMR, 13C NMR and HR-MS techniques. Screening in vitro of their peroxisome proliferator-activated receptor (PPAR) activation activities showed weak relative PPAR activation activities to most of the target molecules. However, 4 target molecules exhibit PPAR over 58%, and as high as 81.79% for TM2-i, presenting itself as potent leading compound for antidiabetic drugs. This research also confirms that it is probable to achieve esterification of carboxyl group and deacylation of fatty acid N-phenyl amides concurrently in SOCl2/alcohol solvent system. This provides new synthetic method for the selective reaction within molecules containing both carboxyl and N-aryl amido groups of fatty acids.

OBJECTIVETo observe the role of interleukin (IL) 21 alone, IL12 alone, and IL21 plus IL12 for inducing the antitumor activity of peripheral blood mononuclear cells (PBMCs) in patients with endometrial cancer.

METHODSPBMCs were isolated from peripheral blood in patients with endometrial cancer in vitro, and kept the culture with low-level IL2. IL2-stimulated PBMCs were cocultured under different conditions (with anti-IL21 antibody, IL21 alone, IL12 alone, or IL21 plus IL12) for 72 h. The cytotoxicity of PBMCs was then examined by lactate dehydrogenase(LDH) released assay. CD4(+) CD25(+) FOXP3(+) regulatory (Treg) cell and CD4(+) IL17A(+) T-helper (Th17) cell proportion were determined with flow cytometry. Cell proliferation and apoptosis were measured by cell counting kit-8(CCK-8)assay and flow cytometry, respectively.

RESULTSIn comparison to control group, both IL21 and IL12 significantly enhanced the cytotoxicity of PBMCs. The IL21 plus IL12 group had superior effect to IL21 alone and IL12 alone. IL21 and IL12 significantly decreased the percentages of Treg cells and the rate of PBMCs apoptosis. IL21 or IL12 had no significant effect on the differentiation of Th17 cells and the proliferation of PBMCs.

CONCLUSIONSIL21 and IL12 can enhance the cytotoxicity of PBMCs in patients with endometrial cancer, which can be further strengthened with treatment of IL21 plus IL12. Such effects may be achieved by inhibiting the differentiation of Treg cells and the apoptosis of PBMCs, but not by the differentiation of Th17 cell.
