OBJECTIVETo investigate the role of p38 MAPK on ischemic postconditioning (IPO) attenuating pneumocyte apoptosis after lung ischemia/reperfusion injury (LIRI).
METHODSForty adult male SD rats were randomly divided into 5 groups based upon the intervention (n = 8): control group (C), LIR group (I/R), LIR + IPO group (IPO), IPO + solution control group (D), IPO + SB203580 group (SB). Left lung tissue was isolated after the 2 hours of reperfusion, the ratio of wet lung weight to dry lung weight (W/D), and total lung water content (TLW) were measured. The histological structure of the left lung was observed under light and electron transmission microscopes, and scored by alveolar damage index of quantitative assessment (IQA). Apoptosis index (AI) of lung tissue was determined by terminal deoxynuleotidyl transferase mediated dUTP nick end and labeling (TUNEL) method. The mRNA expression and protein levels of and Bax were measured by RT-PCR and quantitative immunohistochemistry (IHC).
RESULTSCompared with C group, W/D, TLW, IQA, AI and the expression of Bax of I/R were significantly increased, the expression of Bcl-2 and Bcl-2/Bax were significantly decreased (P < 0.05, P < 0.01), and was obviously morphological abnormality in lung tissue. Compared with I/R group, all the indexes of IPO except for the expression of Bcl-2 and Bcl-2/ Bax were obviously reduced, the expression of Bcl-2 and Bcl-2/Bax were increased (P < 0.05, P < 0.01). All the indexes between D and IPO were little or not significant( P > 0.05). The expression of Bcl-2 and Bcl-2/Bax of SB were significantly increased and other indexes were reduced than those of IPO (P < 0.05, P < 0.01).
CONCLUSIONIPO may attenuate pneumocyte apoptosis in LIRI by inactivation of p38 MAPK, up-regulating expression of Bcl-2/Bax ratio.

AIM:To investigate the mechanism of lipotoxicity-associated apoptosis mediated by mitochondrial pathway in pancreatic β-cells. METHODS:The pancreatic β-cell line MIN6 cells were incubated respectively in serum-free DMEM medium with or without palmitate (0.1-0.5 mmol/L) for 24 h,followed by Hoechst 33258 staining. The activity of caspase 3 was assayed for determining apoptosis,transmission electron microscope was used for observing mitochondrial structure,and RT-PCR analysis was applied for detection of mRNA expression of bcl-2-associated X protein (bax),B-cell lymphoma 2 (bcl-2),sterol regulatory element binding transcription factor 1c (SREBP1c) and DNA-damage inducible transcript 3 (chop-10). RESULTS:Palmitate induced apoptosis of MIN6 cells and swelling of mitochondria. Palmitate also inhibited mRNA expression of bcl-2,whereas enhanced mRNA expression of bax,SREBP1c and chop-10. CONCLUSION:Palmitate induces apoptosis of pancreatic β-cells by promoting mitochondrial dysfunction,which is associated with abnormal expressions of bax,bcl-2,SREBP1c and chop-10.

Objective To study the expressions of programmed death 1 (PD-1) and programmed death ligand 1 (PD-L1) in liver injury of acute liver failure (ALF) in rats and the role of PD-1/ PD-L1 in liver inflammatory injury. Methods SD rats were divided into two groups: 6 in normal group and 30 in ALF model group. The ALF models in rats were induced by D-galactosamine (D-Gal). The sera and hepatic tissue samples were collected at 12, 24, 48, 72 and 120 hours after D-Gal injection. Expressions of PD-1 mRNA and PD-L1 mRNA in hepatic tissue samples were detected by reverse transcription-polymerase chain reaction (RT-PCR). Comparison of measurement data between groups was done by t test. Correlation test was performed using Pearson linear correlation analysis. Results The levels of alanine animotransferase (ALT) and aspartate animotransferase (AST) at 12 h of D-Gal injection were (217. 3±33. 7) U/L and (397. 2± 101.3) U/L, respectively,which were both significantly higher than those in normal group [(30. 5 ±3. 1) U/L and (78. 6±4.2) U/L, respectively; t=-8. 921 and -6. 121, respectively; both P<0.01] and peaked at 48 h.The expression of PD-1 mRNA in model group at 12 h (0. 385±0. 074) was significantly higher than that in normal group (0. 097±0.009) (t= -7. 725, P<0.01) , and peaked at 48 h (0. 927±0. 132),then decreased obviously at 72 h. The expression of PD-L1 mRNA in the liver tissue of normal rats was very little, while that in model group was increased gradually over time, then peaked at 48 h (0. 593±0. 105; t =- 10. 076, P<0. 01). The expressions of PD-1 and PD-L1 were positively correlated with ALT level (r=0. 807 and 0. 792, respectively; both P<0. 01). Conclusion The expressions of PD-1/PD-L1 may play an important role in liver inflammatory injury in rat model of acute liver failure.

OBJECTIVETo study whether acupressure could relieve urinary retention after radical hysterectomy in cervical cancer patients.
METHODSA randomized controlled prospective double-blinded trial was carried out in 107 urinary retention patients undergoing grade III radical hysterectomy. They were assigned to Group A (positive acupoints, 40 cases), Group B (negative acupoints, 32 cases) , and Group C (with no acupoints, 35 cases). All patients received protective 115 000 potassium permanganate sitz bath, 15 - 20 min each time, 3 times per day. Patients in Group A received acupressure at positive points [liniao point and Qihai (RN6)] combined points by syndrome typing [Guanyuan (RN4) , Zhongji (RN3) , Shenshu (BL23) , Zusanli (ST36), Sanyinjiao (SP6), and Taixi (K13)]. Patients in Group B received negative acupressure at sham-acupoints (for adjusting gastrointestinal functions). Patients in Group C only received conventional sitz bath. All medication was performed 3 times per day, 7 days as one therapeutic course, 21 days in total. The residual urine volume was detected. The recovery time for bladder function was recorded. The average residual urine volume was also recorded at day 7, 14, and 21.
RESULTSCompared with Group B and C, the time for ureter retention was shortened for mild and severe CKD patients in Group A (P <0. 01). The residual urine volume was also lessened for mild and severe CKD patients in Group A at day 7, 14, and 21 (P <0.01).
CONCLUSIONCervical cancer patients could relieve urinary retention by self-acupressure after radical hysterectomy.
