Objective:To observe the clinical efficacy of acupuncture plus turtle-shell-partitioned moxibustion in treating diarrhea- predominant irritable bowel syndrome (IBS-D). Methods:Seventy-six patients were randomized into two groups: 39 cases in the observation group were intervened by acupuncture plus turtle-shell-partitioned moxibustion, while 37 cases in the control group by the same acupuncture treatment, once a day, 10 d as a treatment course, for 2 courses in total. The improvements of symptoms were observed at the end of the intervention in both groups. Results:The total effective rate was 89.7% in the observation group versus 67.6% in the control group, and the difference was statistically significant (P<0.05).Conclusion:Acupuncture plus turtle-shell-partitioned moxibustion can significantly improve the symptoms of IBS-D, and can produce a more significant efficacy than acupuncture alone.

Objective: To observe the impact of mind-regulating acupuncture plus donepezil on the cognitive ability, mean cerebral blood flow velocity, event-related potential P300, and activities of daily living (ADL) in the aged patients with Alzheimer disease (AD).Methods: Sixty senile AD patients were divided into a treatment group and a control group following the envelope method for random allocation, with 30 cases in each group. Based on the conventional treatment of the internal medicine, the control group received oral donepezil, and the treatment group received oral donepezil plus mind-regulating acupuncture. After 4-week treatment, the two groups were evaluated by the mini-mental state examination (MMSE), Alzheimer disease assessment scale-cognitive part (ADAS-Cog), and ADL; changes in P300 and the mean cerebral blood flow velocity were also observed.Results: Before treatment, there were no significant differences in the scores of MMSE, ADAS-Cog, or ADL between the two groups (P>0.05). The MMSE score increased after treatment in both groups and was notably higher in the treatment group than in the control group, showing intra-group and inter-group statistical significance (P<0.05). After treatment, the ADAS-Cog and ADL scores dropped in both groups and were markedly lower in the treatment group than in the control group, also showing intra-group and inter-group statistical significance (P<0.05). Compared with the same group before treatment, the latency of P300 was shortened and the amplitude was extended in both groups, all with statistical significance (P<0.05); the latency was shorter and the amplitude was larger in the treatment group than in the control group after treatment, presenting significant between-group differences (P<0.05). The mean blood flow velocity accelerated after the intervention in both groups, and the differences were statistically significant (P<0.05); the improvement in the treatment group was more notable than that in the control group (P<0.05).Conclusion: Mind-regulating acupuncture plus donepezil can regulate the latency and amplitude of P300, increase cerebral blood flow, and improve the learning and memory abilities of AD patients.

Objective To prospectively evaluate the sensitivity and specificity of ankle brachial index (ABI) in the diagnosis of lower extremity arterial disease(LEAD)by using conventional digital subtraction angiography (DSA) as the reference standard, and to research the threshold value of ABI screening test for diagnosis. Methods A total of 383 consecutive patients (245 men and 138 women, mean age (64.1±11.7) years] underwent conventional DSA and ABI measurement. Receiver operator characteristics (ROC) analysis was performed to assess possible threshold values for predicting the LEAD in these patients. Results Conventional DSA was used as the gold standard in defining≥50% luminal stenosis for the diagnosis of LEAD. 0. 95 was the overall cutoff of ABI which was associatcd with 93.0% sensitivity, 85.0% specificity, 8.81 positive likelihood ratio(+LR) and 0. 23 negative likelihood ratio(-LR) for detection of hemodynamically significant stenosis (lesions>≥50%) in all 383 subjects (P<0.01). The area under the ROC curve was 0. 953(95%CI 0.920～0.985). Conclusions ABI measurement is an accurate and reliable non-invasive alternative to conventional DSA in the diagnosis of lower extremity arterial disease. And the cut-off 0.95 is the threshold ABI value for detecting LEAD in Chinese population.

ObjectiveTo explore the effects of epidermal proteins and lamellar bodies on skin barrier in glucocorticoid-dependent dermatitis.MethodsTotally,60 patients with glucocorticoid-dependent dermatitis and 40 normal human controls were eligible for this study.A noninvasive method using TewameterTM was applied to determine transepidermal water loss (TEWL) value in these subjects.Tissue specimens were obtained from the lesions of 13 patients with glucocorticoid-dependent dermatitis and normal skin of 10 human controls.Subsequently,haematoxylin and eosin(HE) staining was performed to observe the histopathological changes,immunohistochemistry to detect the protein expressions of K6,K10,K14,K15,loricrin,filaggrin,involucrin in epidermis,and electron microscopy(EM) to estimate the density of lamellar bodies in tissue specimens.ResultsCompared with the normal controls,the patients displayed an elevated TEWL value (P ＜ 0.05),which suggested an impaired epidermal barrier.Histopathology of lesions revealed nonspecific inflammatorychanges withmarkeddifferencesbetweendifferentclinicaltypesofglucocorticoid-dependentdermatitis.Immunohistochemistry revealed an attenuated expression of K10,K14,loricrin,filaggrin,involucrin and abnormal expression of K15 in lesional epidermis compared with the normal epidermis (all P ＜ 0.05),hinting a suppression of epidermal differentiation and proliferation as well as an impairment of cornified envelope structure.The number and density of lamellar bodies were also reduced in lesional epidermis compared with the control epidermis.ConclusionsCompared with normal skin,the structure of skin barrier is impaired in lesions of glucocorticoid-dependent dermatitis,to restore skin barrier is essential for the treatment of this entity.

In the present study, the intracellular free calcium concentration ([Ca(2+)](i)) in acutely isolated rat dorsal root ganglia (DRG) neurons modulated by loureirin B, an active component of "dragon's blood" which is a kind of Chinese herbal medicine, was determined by the means of Fura-2 based microfluorimetry. It was found that loureirin B could evoke the elevation of [Ca(2+)](i) in a dose-dependent manner. However, the elevation of [Ca(2+)](i) evoked in the calcium free solution was much smaller than that in the standard external cell solution, suggesting that most change of [Ca(2+)](i) was generated by the influx of extracellular Ca(2+), not by the activities of intracellular organelles like Ca(2+) stores and mitochondria. In addition, the mixture of loureirin B and caffeine also induced [Ca(2+)](i) rise, but the peak of [Ca(2+)](i) rise induced by the mixture was significantly lower than that by caffeine alone, which means the triggering pathway and the targets of caffeine are probably involved in loureirin B-induced [Ca(2+)](i) rise. Moreover, compared to the transients induced by caffeine, KCl and capsaicin, the loureirin B-induced [Ca(2+)](i) rise is much slower and more stable. These results indicate that the capability of loureirin B of inducing the [Ca(2+)](i) rise is solid and unique.

BACKGROUNDTo explore the therapeutic effect of bronchial artery infusion chemotherapy combined with immunotherapy for lung cancer with malignant hydrothorax.

METHODSSeventy-five lung cancer patients with malignant hydrothorax were randomly divided into the two groups: 38 patients were given intrathoracic chemotherapy and bronchial artery infusion chemotherapy combined with immunotherapy as observing group; 37cases only received intrathoracic chemotherapy as control group. Chi-square assay was performed to analyze the efficacy (responses for lung cancer and hydrothorax control) after the first course of treatment and the 1-, 2-year survival rates in the two groups.

RESULTSAfter the first course of treatment, the total responses for lung cancer were 31.58% (12/38) and 5.41% (2/37) in the observing group and control group (Chi-square=8.46, P < 0.01) respectively ; and responses for hydrothorax control were 86.84% and 64.86% respectively (Chi-square= 4.96, P <0.05). The 1- and 2-year survival rates in the observing group were 65.79% (25/38) and 26.32% (10/38) respectively, which were significantly higher than those of the control group (40.54% and 5.41%) respectively (Chi-square=4.80, P <0.05; Chi-square=6.10, P <0.05).

CONCLUSIONSThe intrathoracic chemotherapy combined with bronchial artery infusion chemotherapy and immunotherapy is quite effective in the treatment of lung cancer with malignant hydrothorax.

OBJECTIVETo evaluate the value of measuring ankle brachial index (ABI) for diagnosing peripheral arterial disease(PAD) compared with conventional digital subtraction angiography (DSA) as the reference standard.

METHODSA total of 383 consecutive inpatients (245 male, mean age 64.1 +/- 11.7 years) underwent both conventional DSA and ABI measurements.

RESULTSThe rate of statin intervention was 90.9%, ACEI 69.2%, antiplatelet 96.6% and beta-blockers 67.9%. The intravascular stenosis was classified into six degrees: normal, < 30%, 30% - 49%, 50% - 69%, 70% - 89% and > or = 90%. Compared to the traditional gold standard (DSA) in diagnosis PDA, the ABI value decreased in proportion to the severity of PAD (the ABI value was 1.08 +/- 0.11, 1.05 +/- 0.16, 0.99 +/- 0.17, 0.66 +/- 0.24, 0.55 +/- 0.28 and 0.54 +/- 0.00 respectively in the six ranks). There was a significant correlation between DSA and ABI in diagnosis PAD.

CONCLUSIONABI measurement is an accurate and reliable non-invasive alternative to conventional DSA in the assessment of lower extremity arteries in patients with peripheral arterial disease.

Objective To compare the effects of 3D laparoscopic hepatectomy (3D-LH) and open hepatectomy(OH)in glissonian access for hepatocellular carcinoma(HCC)on postoperative immunosuppression by analyzing cellular immune function. Methods During January 2014 to December 2017,sixty patients randomly scheduled to undergo hepatectomy were divided into 3D-LH group and OH group,with 30 patients in each group. All patients' peripheral blood was sampled to measure cell-mediated-immunologic markers(CD4+,CD8+T cell) before operation and in the mornings of the 1st,7thday after surgery. The effects of different operative methods on cellular immune function in patients organism were investigated. Results The decreased level in 3D-LH group was less than that in OH group in postoperative 1stday. The improvement in the 3D-LH group was more faster than that in the OH group on postoperative 7thday. There was statistical significance between the two groups(P<0.05), respectively. Conclusion When compared to open hepatectomy ,3D laparoscopy liver resection in glissonian approach for HCC,less effects in cellular immune function.

AIM: To investigate the effects of agkis-trodon halys venom anti-tumor component (AHVAC-) on the biological behavior of gastric cancer MKN-28 cells. METHODS: Gastric cancer MKN-28 cells were treated with the experimental concentrations (5, 10, 15 μg/mL) of AHAVC- for 24 h. Cell proliferation and toxicity assay (cell counting kit-8, CCK-8) was used to detect the inhibition rates of the cells in different concentrations of AHVAC-. The migration ability of the cells was evaluated by wound-healing and Transwell assay. The apoptosis were observed by laser confocal microscopy with annexin V-mCherry/DAPI double staining, and the apoptosis rates were analyzed by flow cytometry with annexin V-FITC/PI double fluorescence staining. The protein level of Caspease-3 was determined by Western blot. RESULTS: Compared with normal control group, the results of AHVAC- concentration groups showed that with the increase of AHVAC- concentration, the proliferative activity of MN-28 cells decreased gradually (P<0.01), the cell migration ability decreased gradually (P<0.01), and the cell apoptosis rate increased (P<0.05). The expression of apoptosis-related protein Caspease-3 was up-regulated (P<0.01). CONCLUSION: AHVAC- inhibits proliferation and migration of gastric cancer MSN-28 cells and induces apoptosis.

Aim To explore the possibility of resveratrol ( RES) combined with irinotecan ( IRI) in the treatment of colorectal cancer ( CRC ) and the underlying molecular mechanism of RES ameliorating IRI chemoresistance of CRC cells. Methods CRC cells used in this study were HT-29 and RKO cells. The effects of RES, IRI and their combination on the proliferation of CRC cells were analyzed by MTT assay and colony formation assay. The effects of RES,IRI and their combination on the migration of CRC cells were assessed by Wound-healing assay. On this basis,the role of RES in regulating IRI chemoresistance of CRC cells and the underlying molecular mechanisms were further explored. Results The proliferation and migration ability of CRC cells in the RES and IRI combined treatment group were significantly lower than those in the IRI treated group, which showed that RES could enhance the inhibiting effect of IRI on the proliferation and migration of CRC cells, indicating that RES was able to a-meliorate the chemoresistance of CRC cells to IRI. And remarkably lower marker proteins expression levels of EGFR/AKT/mTOR signaling pathway in the RES and IRI combined treatment group was observed. Moreover, both EGFR activator (NSC 228155) and AKT activator (SC79) could reverse the ameliorating effect of RES on IRI chemoresistance of CRC cells, whereas AKT inhibitor (MK2206 ) could partially reverse the effect of NSC 228155. Conclusions RES can inhibit the proliferation and migration of CRC cells by down-regulating EGFR/AKT/mTOR signaling pathway, so as to ameliorate the chemoresistance of CRC cells to IRI, suggesting that RES combined with IRI can be a promising novel treatment for CRC.
