Objective To investigate Yiqi Huatan Decoction(YHD), a compound recipe with the actions of tonifying Qi and resolving phlegm, on aquaporin 5(AQP5), tumor necrosis factor-alpha(TNF-α)and mucin 5AC(MUC5AC)in bronchoalveolar lavage fluid(BALF)of chronic obstructive pulmonary diseases(COPD)rats. Methods SD rats were randomized into blank control group, model group, and low-, middle- and high-dose YHD groups(in the dosage of 7.398, 36.99, 73.98 g·kg-1·d-1 respectively). The rat model of COPD was induced by cigarette smoking combined with intratracheal dripping of lipopolysaccharide(LPS). After COPD rats were treated with YHD for 30 days, the histological features of lung tissues were observed after hematoxylin-eosin (HE) staining, the expression of AQP5, TNF -α and MUC5AC in the lung tissue was detected by immunohistochemistry, the concentrations of AQP5, TNF-α and MUC5AC in BALF of rats were measured by enzyme-linked immunosorbent assay(ELISA). Results Compared with the blank control group, the concentration of AQP5 in BALF of the model group was decreased significantly(P<0.01), while the concentrations of TNF-αand MUC5AC were significantly increased(P<0.01). Compared with the model group, the pathological features of the lung tissue were relieved, and the concentration of AQP5 was increased significantly in low-, middle-, high-dose YHD groups (P<0.01), but the concentrations of TNF-α and MUC5AC were significantly decreased (P<0.01), and the effect of high-dose group was superior to low-and middle-dose groups(P<0.01). Conclusion The therapeutic mechanism of YHD for COPD is probably related with the regulation of fluid transport in aquaporin water channels of rats.

Objective To explore the mechanism of HSP70 on cell cycle regulation in hepatic IR (ischemia-reperfusion) injury.Methods SD rats were randomly divided into HSP70 inhibitor group (H-/P+),heat shock group (H+/P+),PARP-1 inhibitory group (H +/P-),IR group (PC) and negative control group (NC),respectively.After the IR model was induced,the liver specimen underwent IHC staining to observe the changes of the PARP-1 expression;Co-immunoprecipitation was used to detect the binding of HSPT0 with PARP-1.Results H +/P-was significantly different from H +/P +,H-/P +,PC,NC (P ＜ 0.01);Immunoprecipitation suggested that HSP70 entered into the nucleus to bind PARP-1,and immunofluorescence imaging analysis demonstrated both HSP70 and CyclinD1 expressed at the same timeline.Conclusion Under reversible hepatic ischemia-reperfusion injury,HSP70 enters the nucleus and binds to PARP-1,negatively regulates G2/M phase,blocks cells for DNA replication and recombination,blocks its entry into mitosis,repairs damaged DNA chain;Liver ischemia-reperfusion positively regulates the G1/S phase,promoting hepatocyte regeneration and liver function compensation.

Objective To observe the influences on prognoses and airway acid and base levels while using anti-inflammatory and anti-reflux therapies combined with "Hezhong Fuzheng massage" for treatment of infants with gastric volvulus (GV) and gastroesophageal reflux (GER)-induced pneumonia in order to provide evidence for clinical diagnosis and treatment of such infant disease. Methods Sixty infants 1-6 months old admitted to the Department of Integrated Traditional Chinese and Western Medicine of Wuhan Children's Hospital from January 2013 to December 2015 were diagnosed as pneumonia combined with GV and GER by the chest radiograph and radiography of upper gastrointestinal tract (UGT) with iodine, and according to difference in diagnostic methods, they were divided into an observation 1 group (30 cases) and an observation 2 group (30 cases). In observation 1 group, 24-hour pH value in upper digestive tract especially the distal esophagus was dynamically monitored, while in observation 2 group, 24-hour multichannel intraluminal impedance (MII) combined with pH monitoring of esophagus was carried out. Furthermore, two control groups were set up, each 30 cases; after radiography of the UGT with iodine, the control 1 group was diagnosed as GV and GER without pneumonia and control 2 group was diagnosed as only simple GV. Treatment of infant pneumonia was carried out in accordance with the guidelines for the management of community-acquired pneumonia in children; the treatment of GV and GER included postural, dietary, prokinetic and Hezhong Fuzheng massage [acupoint selection and massage was undertaken in 5 steps: push from the palmar crease to Banmen (rectilinear pushing manipulation) 300 times, push abdominal Yin and Yang (finger-pushing massage) 200 times, palpate the abdomen (clockwise) 100 times, poking of Tianshu 100 times, poke alternately bilateral Zusanli 100 times. Once-daily massage, (15±2) minutes each time, for consecutive 7 days]. The results of pH monitoring of the distal esophagus in observation 1 group was recorded; All GER data concerning pH monitoring of observation 2 group and the results of esophagus multi-channel intra-luminal impedance combined with pH monitoring in control group were compared. After 7 days of continuous treatment, the clinical efficacy of pneumonia and GV, hospitalization time, prognosis and the changes of sputum pH before and after treatment in the two observation groups were compared. Results In two observation groups, the main type of 60 cases with GV was organoaxial volvulus, accounting for 91.67% (55 cases), and more than 60% patients exhibited sputum pH <7.0. The distal esophagus 24-hour pH dynamic monitoring in observation 1 group showed that there were 26 cases with acid reflux (86.67%), 4 cases with GER negative (13.33%), the proportion of pH < 4 in GER negative patients was significantly lower than that in moderate acid reflux patients [3.35% (0.77% - 8.08%) vs. 26.23% (15.19% - 42.87%), P < 0.05], the number of long reflux (> 5 minutes) in GER negative patients was significantly reduced than that in mild acid reflux patients [times: 2 (0-5) vs. 7 (2-15), P < 0.05], the longest time of reflux in GER negative patients was significantly shorter than that in either mild or moderate acid reflux patients [minutes: 5.9 (2.5-10.0) vs. 19.2 (5.9-51.0), 41.6 (16.9-121.0), both P < 0.05]. The 24-hour MII-pH monitoring of esophagus in observation 2 group showed that there were 30 cases with pathological reflux, mainly mild acid reflux accounting for 90%, in which the percentage of proximal reflux events was 46.07% in the total reflux events. The numbers of acid reflux and proximal reflux in the observation 2 group were significantly higher than those in the control 1 and 2 groups [1 305 (37.72%) vs. 795 (25.69%) and 136 (18.89%), 1 594 (46.07%) vs. 687 (22.20%) and 154 (21.39%), both P < 0.05]; there were no significant differences in total effective rate (100% vs. 100%, P > 0.05) and hospitalization time (days: 7.58±1.09 vs. 7.67±1.12, P > 0.05) between the two observation groups. Conclusions For the diagnosis of infant pneumonia combined with GV and GER, the first selection of chest radiograph and radiography of the UGT with iodine can identify the severity of pneumonia, whether it is complicated with GV and its classification, and whether GER exists at the same time. The estimation of 24-hour pH dynamic monitoring of the acid reflux in the upper digestive tract especially the distal esophagus is consistent with that of the 24-hour MII-PH monitoring of esophagus. Moreover, 24-hour MII-PH monitoring of esophagus can also identify non-acid reflux, resulting in the GER diagnosis more accurate. Since the proximal reflux ratio of infants with GV combined with GER and pneumonia is relatively high and easy to cause cough and aspiration. attention should be paid on early diagnosis and timely intervention to such patients. The sputum acidity test can reflect the airway acid-base level and its manipulation is simple, so by that the real time disease situation can be estimated, and aspiration of sputum also can help the treatment. The therapeutic schedule formulated by our group can elevate the therapeutic effect, improve the airway acid-base environment and benefit prognosis.
