OBJECTIVETo observe the effect of Wenyang Huoxue Lishui Recipe (WHLR) containing serum on the expression of cathepsin L (CatL) in puromycin aminonucleoside-induced injury of mouse glomerular podocytes.
METHODSMouse podocyte cells (MPCs) in vitro cultured were divided into the normal control group, the model group, the dexamethasone (DEX) group, 10% WHLR containing serum group, 20% WHLR containing serum group, the vehicle serum control group. MPCs in the normal control group were cultured at 37 degrees C culture solution for 24 h. 45 mg/L puromycin was acted on MPCs in the model group for 24 h. On the basis of puromycin intervention, 1 limol/L DEX was co-incubated in MPCs of the DEX group for 24 h; 10% or 20% WHLR containing serum was co-incubated in MPCs of the 10% WHLR containing serum group and 20% WHLR containing serum group for 24 h. The vehicle serum control group was also set up by incubating with WHLR containing serum alone for 24 h. The expression of CatL and its substrate Synaptopodin in podocytes were detected by cell immunofluorescence staining. FITC-conjugated phalloidin was used to stain F-actin. A cortical F-actin score index (CFS index) was designed to quantify the degree of cytoskeletal reorganization in cultured podocytes.
RESULTSCompared with the normal control group, the expression of synaptopodin significantly decreased and the expression of CatL significantly-increased in the model group. F-actin arranged in disorder, gradually forming pericellular F-actin ring. CFS index was obviously elevated (P < 0.01). Compared with the model group, the epression of synaptopodin increased, the expression of CatL decreased, and CFS index also decreased in the DEX group, 10% WHLR containing serum group, and 20% WHLR containing serum group (P < 0.05, P < 0.01). Compared with the DEX group, the expression of synaptopodin decreased in 10% WHLR containing serum group, CFS index also decreased in 20% WHLR containing serum group (P < 0.05).
CONCLUSIONSWHLR could up-regulate the expression of synaptopodin, down-regulate the expression of CatL, and alleviate cytoskeletal reorganization of F-actin. It was helpful to stabilize the cytoskeleton of F-actin and improve the merging of podocytes.

Objective To discuss the effect of early comprehensive development mode on physical, intelligence and mental development of premature infants, and explore the feasibility of comprehensive development mode of preterm infants generally applied in child care clinic. Methods 90 cases of premature infants in intervention group from the beginning of the hospital before the intervention, continuous monitoring and comprehensive intervention including general system health, parenting guidance, family activities, growth monitoring, intelligence assessment, individualized instruction, and so on, for the timely correction of the anomalies. The 90 infants in the control group were only given conventional child health care after 1 month of corrected age. Results The nervous system abnormalities were detected 192 person-times in control group, while 129 person-times in intervention group at 3 months old, the detected rate of nervous system anomaly was higher in the control group than that in the intervention group (χ2=14.574, P=0.000). The body length of the intervention group was (74.31± 2.34) cm, the control group was (72.82 ± 2.13) cm. The body weight of the intervention group was (9.42 ± 0.93) kg, the control group was (8.11 ± 0.90) kg at 12 months old. The growth of weight and length of intervention group were higher than those of control group. The difference was statistically significant ( t=4.467, 9.602, P < 0.05). The development quotient was also assessed, the big activity sport, fine motor, adaptability, social behavior, development quotient of intervention group were (96.40±7.83) points, (95.45± 7.87) points, (98.33±10.87) points, (105.65±7.51) points, (101.45±7.36) points, and the control group were (92.53±6.57) points, (89.27±8.02) points, (94.26±9.88) points, (100.31±8.13) points, (95.65±6.93) points. The difference was statistically significant (t=2.628-5.443, P < 0.05). Conclusions Application of integrated early childhood development in premature infants can find early neurodevelopmental deviations of children and contribute to early intervention on premature infants. Using a combination of family and outpatient intervention may reduce the incidence of neurological abnormalities, improve the level of development of the intelligence assessment and promote premature infant intelligence, motor development and social adaptation ability.

This study explored the molecular mechanisms underlying the time-dependent autophagy and apoptosis induced by nutrient depletion in human multiple myeloma cell line RPMI8226 cells. RT-PCR and qRT-PCR were used to evaluate the transcriptional levels of Deptor, JNK1, JNK2, JNK3, Raf-1, p53, p21 and NFκB1 at 0, 6, 12, 18, 24 and 48 h after nutrient depletion in RPMI8226 cells. We found that transcriptional levels of Deptor were increased time-dependently at 0, 6, 12 and 18 h, and then decreased. Its alternation was consistent with autophagy. Transcriptional levels of Raf-1, JNK1, JNK2, p53 and p21 were increased time-dependently at 0, 6, 12, 18, 24 and 48 h accompanying with the increase of apoptosis. Transcriptional levels of NFκB1 at 6, 12, 18, 24 and 48 h were decreased as compared with 0 h. It was suggested that all the studied signaling molecules were involved in cellular response to nutrient depletion in RPMI8226 cells. Deptor contributed to autophagy in this process. Raf-1/JNK /p53/p21 pathway may be involved in apoptosis, and NFκB1 may play a possible role in inhibiting apoptosis. It remained to be studied whether Deptor was involved in both autophagy and apoptosis.
