Aim To investigate whether melatonin ( MT) can alleviate endoplasmic reticulum( ER) stress at an early stage of bleomycin( BLM)-induced lung fi-brosis in mice. Methods Adult healthy male ICR mice were divided randomly into control group, MT group, BLM group and MT + BLM group. In MT group, mice had saline treatment 30 minutes after hav-ing the intraperitoneal injection of MT (10 mg·kg-1 ) and had been intraperitoneally injected with MT once in the following every 24 hours. In BLM group, mice were intratracheally injected with a single dose of BLM (5 mg·kg-1). In MT+BLM group, mice had been intraperitoneally injected with BLM 30 minutes after having MT and had been injected with MT once in the following every 24 hours. In control group, mice re-ceived the same level of saline treatment in the same manner. All mice were dissected for collecting the tis-sue of lungs at different time points (24h, 72h) after BLM treatment. Inflammatory cell infiltration of lungs was determined by HE staining. The level of ER stress related proteins ( GRP78 , p-eIF2α, p-IRE1α) in lungs was determined using Western blot. The distribu-tion of ER stress related proteins ( GRP78 , p-IRE1α, ATF6α, p-PERK) in lungs was detected by immuno-histochemistry. Results The model of BLM-induced acute inflammation of lung fibrosis in mice had been successfully constructed. After BLM treatment, lung weight, lung weight ratio and inflammatory cell infiltra-tion were significantly increased with a significant cor-relation between time and effectiveness. After MT treatment, lung weight, lung weight ratio and inflam-matory cell infiltration were significantly reduced. The results of Western blot showed that MT pretreatment not only prevented the increase of BLM-induced GRP78 protein significantly, but also restrained the phosphorylation of eIF2α and IRE1α in mouse lungs. Immunohistochemistry also showed that MT pretreat-ment reduced the expression of GRP78 , p-IRE1α, ATF6α and p-PERK. Conclusion MT alleviates ER stress effectively at an early stage of BLM-induced lung fibrosis in mice.

OBJECTIVETo observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery.
METHODSA total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups.
RESULTSThere was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05).
CONCLUSIONThe analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.

BACKGROUND:The role of transforming growth factorβsuperfamily has been reported in bone mineralization of various types of stem cells, but the effects of transforming growth factorβ3 (TGF-β3) combined with heparin on proliferation and mineralization of dental pulp stem cells from human deciduous teeth remains to be studied. OBJECTIVE:To evaluate the effects of TGF-β3 on the proliferation and mineralization of dental pulp stem cells from human deciduous teeth. METHODS:The enzyme digestion method was utilized to separately culture dental pulp stem cells from human deciduous teeth. The cellcolony forming efficiency was determined. Flow cytometry was utilized to identify cellsurface marker CD146. Immunochemistry for Vimentin and STRO1 was performed to measure dental pulp stem cells from human deciduous teeth. The third passage dental pulp stem cells from human deciduous teeth cultured in vitro were intervened with heparin and TGF-β3 of 1, 5, 25μg/L mass concentration. The MTS method was applied to measure cellgrowth curves. Alizarin red staining was carried out. The changes in alkaline phosphatase activity were determined with alkaline phosphatase kit. RESULTS AND CONCLUSION:The cellcolony forming efficiency was high. cells were positive for CD146, and strongly positive for Vimentin and STRO1. Dental pulp stem cells from human deciduous teeth were identified. MTS assay indicated that there was no obvious effect on promoting proliferation of dental pulp stem cells from human deciduous teeth after stimulation of TGF-β3. Detection results of alkaline phosphatase activity demonstrated that the combination of TGF-β3 and heparin could strengthen the alkaline phosphatase activity of dental pulp stem cells from human deciduous teeth with increased concentration. Alkaline phosphatase activities were significantly higher in the TGF-β3+heparin group, TGF-β3 group and heparin group than in the control group (P<0.01). Alizarin red staining was positive in the TGF-β3+heparin group, and the staining was strongest in the 5μg/L TGF-β3+heparin group. Results indicated that TGF-β3 combined with heparin promoted mineralization of dental pulp stem cells from human deciduous teeth.

OBJECTIVETo observe the Chinese medical syndrome features of patients with primary liver cancer before and after transcatheter arterial chemoembolization (TACE).
METHODSRecruited were 106 primary liver cancer (PLC) patients treated with TACE at the Department of Hepatobiliary Surgery, First Affiliated Hospital of Guangxi Medical University from May to November 2009. Using self-control study, the distributions of 8 syndrome types were compared, such as qi stagnation syndrome, blood stasis syndrome, excess-heat syndrome, fluid and damp syndrome, qi deficiency syndrome, blood deficiency syndrome, yin deficiency syndrome, and yang deficiency syndrome. The scoring for each syndrome quantization was performed to all patients before and after TACE.
RESULTSEight syndromes occurred in the 106 patients before treatment, amounting to 412 cases. The proportions of syndrome types in PLC patients before TACE were ranked from high to low as blood stasis syndrome [(92 cases, 86.8%)], excess-heat syndrome [(73 cases, 68.9%)], qi stagnation syndrome [(62 cases, 58.5%)], qi deficiency syndrome [(62 cases, 58.5%)], yin deficiency syndrome [(60 cases, 56.6%)], blood deficiency syndrome [(30 cases, 28.3%)], yang deficiency syndrome [(18 cases, 17.0%)], fluid and damp syndrome [(15 cases, 14.2%)]. The 8 syndromes occurred in 456 cases after TACE. The proportions of syndrome types in PLC patients after TACE were ranked from high to low as blood stasis syndrome [(89 cases, 84.0%)], qi deficiency syndrome [(87 cases, 82.1%)], excess-heat syndrome [(85 cases, 80.2%)], qi stagnation syndrome [(52 cases, 49.1%)], yin deficiency syndrome [(49 cases, 46.2%)], blood deficiency syndrome [(42 cases, 39.6%)], yang deficiency syndrome [(32 cases, 30.2%)], fluid and damp syndrome [(20 cases, 18.9%)]. After TACE the proportions of qi deficiency syndrome and yang deficiency syndrome increased with statistical difference (P<0.01, P<0.05). There were no statistical difference in terms of other syndromes between before and after TACE (P>0.05). Blood stasis syndrome and qi stagnation syndrome got the highest quantization scores before TACE. After TACE blood stasis syndrome and qi deficiency syndrome got the highest quantization scores. After TACE the score of qi stagnation syndrome decreased, while that of excess-heat syndrome, qi deficiency syndrome, blood deficiency syndrome, yang deficiency syndrome increased (all P<0.05).
CONCLUSIONSIt's necessary to pay attention to regulating qi, clearing heat, replenishing qi, and removing stasis for treating liver cancer patients. Clearing heat, replenishing qi, enriching blood, and warming yang after TACE should also be paid equal attention to while using syndrome typing methods.

Objective:To study the anatomical correlation between dental arch and the volume of upper airway in patients with obstruc-tive sleep apnea hypoventilation syndrome(OSAHS). Methods: Dental arch architecture and upper airway volume were measured by cone beam CT(CBCT) in the subjects with OSAHS(n=22) and without OSAHS(n=19). The correlation between dental arch and the supper airway volume in OSAHS patients was analyzed. Results:The length of the upper dental arch and the height of palate in OSAHS patients were larger than those of the controls(All, P<0. 05). Cross-sectional area of nasopharynx and retropalatal and the total volume of upper airway were negatively correlated with the palatal height and upper dental arch length(P<0. 05), while positively correlated with upper dental arch of molar regions(P<0. 05). Conclusion:The abnormal shape of upper dental arch is related to the airway vol-ume of nasopharynx and retropalatal region in patients with OSAHS.
