Abstract: Objective　To explore the correlation between levels of hypersensitive C-reactive protein (hs-CRP) and procalcitonin (PCT) in serum and alveolar fluid and severity of disease in children with lobar pneumonia. Methods　A total of 112 children diagnosed with lobar pneumonia from September 2020 to September 2021 were selected as the research subjects. The levels of hs-CRP and PCT in serum and alveolar fluid were detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The children were divided into severe group (clinical pulmonary infection score, CPIS≥6 points) and mild group (CPIS<6 points) according to the severity of disease, and further classified into good prognosis group (cured, improved) and poor prognosis group (uncured) according to their treatment outcomes. The correlation of levels of hs-CRP and PCT in serum and alveolar fluid with disease severity in children and their predictive value on prognosis were analyzed. Results　The levels of serum hs-CRP and PCT in severe group were (17.73±3.26) μg/L and (8.59±1.84) μg/L, which were significantly higher than corresponding (12.58±3.09) μg/L, and (5.62±1.59) μg/L in mild group (P<0.05); the levels of hs-CRP and PCT in alveolar fluid in severe group were (21.25±4.18) μg/L and (8.71±1.54) μg/L, which were significantly higher than corresponding (13.79±2.76) μg/L and (5.38±1.69) μg/L in mild group (P<0.05). The levels of hs-CRP and PCT in serum and alveolar fluid were positively correlated with CPIS scores (r=0.398, 0.441; 0.475, 0.586, P<0.05). The levels of hs-CRP and PCT in serum in poor prognosis group were (20.09±4.20) μg/L and (13.35±2.91) μg/L, which were significantly higher corresponding (8.75±2.19) μg/L and (6.28±1.31) μg/L in good prognosis group (P<0.05). The levels of hs-CRP and PCT in alveolar fluid were (23.70±4.29) μg/L and (10.73±2.04) μg/L, which were higher than corresponding (15.08±3.56) μg/L and (5.79±1.10) μg/L in poor prognosis group (P<0.05). There was no significant difference in AUC between combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators in predicting the prognosis of children with lobar pneumonia (P>0.05). Conclusions　The levels of hs-CRP and PCT in serum and alveolar fluid of children with lobar pneumonia are significantly increased and positively correlated with the severity of disease. However, the predictive value of the combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators for the prognosis of children with lobar pneumonia is comparable.

Recent study demonstrated that insulin-like growth factor-1(IGF-1) could have benefits to improve the learning memory.Exercise can increase IGF-1 level in hippocampus.IGF-1 may mediate exercise inducing learning memory;one of the possible mechanism is that the IGF-1 and brain derived neurotrophic factor(BDNF) has a common regulatory capacity over calcium/calmodulin-dependent protein kinase Ⅱ(CAMKⅡ),mitogen-activated protein kinase Ⅱ(MAPKⅡ) and synapsin-1,and the convergence of multiple signaling pathways mediate synaptic plasticity and improve learning memory.

Objective To evaluate the effects of hydrogen on oxidative stress injury induced by high glucose in Schwann cells and its relationship with PARP-1-dependent cell death (parthanatos).Methods Primary rat Schwann cells were cultured in 96-well plate (1×104 cells/ml,200 μl/well) or in 6-well plate (1 × 106 cells/ml,2 ml/well) with RSM culture medium and were randomly divided into 5 groups (n=30 each):control group (group C),hydrogen group (group H2),high glucose group (group HG),high glucose plus hydrogen group (group HG+H2) and high osmotic control group (group M).The cells were cultured in the common culture medium in C,HG and M groups.The cells were cultured in hydrogen-rich culture medium in H2 and HG + H2 groups.In HG and HG + H2 groups,50 mmol/L of glucose was added to the culture medium.In C and H2 groups,the equal volume of normal saline was added to the culture medium.In M group,mannitol 44.4 mmol/L was added to the culture medium.The cells were then incubated for 48 h.After 48 h of incubation,the cell viability was measured using CCK-8 assay,intracellular reactive oxygen species (ROS) level was detected by flow cytometry,the concentration of 8-hydroxy-2-deoxy Guanosine (8-OHdG) was determined by ELISA,and the expression of poly (ADP-ribose)-polymerase-1 (PARP-1),cleaved-PARP-1,poly (ADP-ribose) (PAR),and apoptosis-inducing factor (AIF) in the total protein and nucleus was measured by Western blot.PARP-1 activity (cleaved-PARP-1/PARP-1) and AIF nuclear translocation were recorded.Results Compared with C and H2 groups,the cell viability was significantly decreased,and PARP-1 activity,expression of ROS,8-OhdG and PAR,and AIF nuclear translocation were increased in HG and HG + H2 groups.Compared with HG group,the cell viability was significantly increased,and PARP-1 activity,expression of ROS,8-OhdG and PAR,and AIF nuclear translocation were decreased in HG+H2 group.There was no significant difference in each parameter between M and C groups.Conclusion Hydrogen can reduce oxidative stress injury induced by high glucose in Schwann cells,and the mechanism is related to inhibition of parthanatos.

Objective To investigate the protective effects and underlying molecular mechanisms of hydrogen (H2) on high glucose-induced poly (ADP-ribose) polymerase-1 (PARP-1) dependent cell death (PARthanatos) in primary rat Schwann cells. Methods Cultured primary rat Schwann cells were randomly divided into five groups: blank control group (C group), H2 control group (H2 group), high osmotic control group (M group), high glucose treatment group (HG group), and H2 treatment group (HG+H2 group). The cells in H2 group and HG+H2 group were cultured with saturated hydrogen-rich medium containing 0.6 mmol/L of H2, and those in three control groups were cultured with low sugar DMEM medium containing 5.6 mmol/L of sugar, and the cells in HG and HG+H2 groups were given 44.4 mmol/L of glucose in addition (the medium containing 50 mmol/L of glucose), the cells in C group and H2 group were given the same volume of normal saline, and the cells in M group were given the same volume of mannitol. Cytotoxicity was evaluated using lactate dehydrogenase (LDH) release rate assays after treatment for 48 hours in each group. The contents of peroxynitrite (ONOO-) and 8-hydroxy-2-deoxyguanosine (8-OHdG) reflecting oxidative stress injury and DNA damage were detected by enzyme linked immunosorbent assay (ELISA). Poly (ADP-ribose) (PAR) protein expression was analyzed by Western Blot, and immunofluorescence staining was used to determine the nuclear translocation of the apoptosis-inducing factor (AIF). Results The cytotoxicity in HG and HG+H2 groups was significantly increased as compared with that of C group [LDH release rate: (61.40±2.89)%, (42.80±2.32)% vs. (9.92±0.38)%, both P < 0.01], the levels of ONOO- and 8-OHdG were markedly elevated [ONOO- (ng/L): 853.58±51.00, 553.11±38.66 vs. 113.56±14.22; 8-OHdG (ng/L): 1 177.37±60.97, 732.06±54.29 vs. 419.67±28.77, all P < 0.01], and the PAR protein expression was up-regulated (A value: 0.603±0.028, 0.441±0.010 vs. 0.324±0.021, both P < 0.01). The cytotoxicity, the levels of ONOO- and 8-OHdG, and PAR expression in HG+H2 group were significantly lower than those of the HG group (all P < 0.01). There were no significant differences in above parameters between H2 group as well as M group and C group. It was shown by immunofluorescence that AIF was expressed in the cytoplasm in C group, H2 group and M group, AIF was expressed in the whole cell in HG group, and the expression in the nucleus was particularly increased. A small amount of AIF expression was found in the nucleus of HG+H2 group, which indicated that high glucose could promote the AIF nuclear translocation, and that hydrogen-rich medium could prevent the process of translocation. Conclusions High glucose levels could enhance DNA damage that enhance PARthanatos in primary rat Schwann cells. However, H2 can not only reduce DNA damage of injured cells, but also inhibit the special death process, reduce the cell toxicity, all of which have protective effects.

BACKGROUND: Recent trials and clinical studies have shown that intracoronary transplantation of bone marrow-derived mesenchymal stem cells (MSCs) improves cardiac function following acute myocardial infarction (AMI). However, whether homing of MSCs into the infarcted myocardium or not is still unknown.OBJECTIVE: To study the homing of MSCs intracoronary administration in porcine myocardial infarction model using in vivo magnetic resonance imaging tracking.METHODS: Porcine MSCs were isolated and cultured by the whole bone marrow method. Following labeling by superparamagnetic iron oxide (SPIO), MSCs were treated with trypsinization to adjust the concentration at 10~(10)/L. Myocardial infarction was induced in all 10 pigs. At one week after modeling, the labeled MSCs were delivered via intracoronary infusion with standard over-the-wire (OTW) balloon angioplasty catheters. Prussian blue staining was used to evaluate labeling efficiency, and double echo steady state was used to scan four-chamber and cor biloculare at long axis view, which was considered as locating phase to obtain image of left ventricle at short axis view. RESULTS AND CONCLUSION: MSCs could be efficiently and safely labeled with SPIO. Intracoronary transplantation of MSCs is able to home the sites of myocardial injury and the border between infarcted and normal tissue. MRI can track SPIO-labeled MSCs delivered through intracoronary and were confirmed on pathology. After 5 weeks the injected labeled cells could still be detected with MRI.

OBJECTIVETo compare the difference in the efficacy on low back pain of cold-damp pattern between electric-thermal Bian-stone therapy and moxibustion box therapy.

METHODSForty-one cases of low back pain of cold-damp pattern were randomized into an electric-thermal Bian-stone therapy group (group A, 26 cases) and a box moxibustion therapy group (group B, 15 cases). In the group A, the electric-thermal Bian-stone was placed over Shenshu (BL 23) and Weizhong (BL 40). The temperature of stone was adjusted in accordance with patient's comfort. In the group B, moxibustion box was used over Shenshu (BL 23) and Weizhong (BL 40). The treatment was given once every day or every two days. Ten treatments made one session. The symptom and physical signs score of low back pain and the score of cold-damp syndrome were observed before and after treatment in the patients.

RESULTSThe symptom and physical signs score of low back pain and the score of cold-damp syndrome were all improved in the two groups (all P < 0.01). The changing rate of symptom and physical signs and syndrome were (37.04 +/- 32.68)% and (22.85 +/- 29.95)% in the group A, and were (47.29 +/- 22.08)% and (23.89 +/- 22.53)% in the group B, respectively, without significant difference in comparison between the two groups (all P > 0.05).

CONCLUSIONThe efficacy on low back pain of cold-damp pattern treated with the electric-thermal Bian-stone therapy is similar to that of moxibustion box therapy. This therapy is characterized as more convenient, safer operation and less pollution.

Objective To explore the expression of sex determining region Y-box 18 (SOX18) in prostate cancer(PCa) and its role on prostate cancer cells.Methods The expression of SOX18 in 98 PCa tissues and 81 adjacent non-tumor tissues was detected by immunohistochemistry.The expression of SOX18 mRNA and protein in PCa cell lines were detected by q-PCR and Western blotting analysis,respectively.After knocking down SOX18 with si-RNA,the proliferation,migration and invasion of PCa cells were analyzed by CCK8,Transwell and Matrigel assays in vitro.Results The rate of high SOX18 expression in prostate cancer tissues was 73.5％ (72/98),which was higher than that in adjacent normal tissues (43.2％,35/81) (P ＜ 0.01).In addition,the rates of high SOX18 expression in clinical stage Ⅲ-Ⅳ [83.7 ％ (36/43) vs.65.5 ％ (36/55),x2 =4.131,P =0.042],pathological grading G3-4 [88.6％ (39/ 44) vs.61.7％ (33/54),x2 =9.424,P =0.002] and Gleason scores ≥ 8 [85.0％ (34/40) vs.65.0％ (38/58),x2 =4.610,P =0.032] groups were higher than those in clinical stage Ⅲ-Ⅳ,pathological grading G1-2 and Gleason scores ≤7 groups.However,there were no differences in the rate of high SOX18 expression in different age groups [77.3％ (38/54) vs.70.4％ (34/44),x2 =0.539,P =0.441].Knockdown of SOX18 notably suppressed the proliferation,migration and invasion of prostate cancer cells.Conclusions SOX18 is over-expressed in prostate cancer,and could promote the proliferation,migration and invasion ability of prostate cancer cells.

Objective To study the cell vitality and ultra-structure of in vitro cultured fetus chondrocytes exposed to different doses of fluoride.Methods Primary chondrocytes were obtained from articular cartilage of the 24-27 weeks,aborted and dead fetuses.The third generation of primary cultured chondmcytes were exposed to concentrations of 0,10-2,5 × 10-3,10-3,10-4,10-5,10-6,10-7 and 10-8 mol/L fluoride for 24,48 and 72 h.Cell vitality was detected with Cell Counting Kit-8 (CCK-8) and ultra-structure of chondrocytes was observed by transmission electron microscope.Results The cell vitalities of chondrocytes exposed to doses of fluoride (10-2,5 ×10-3,10-3,10-4,10-5,10-6,10-7 and 10-8 moL/L) for 24,48 and 72 h were(15.04 ± 0.55)％,(62.53 ± 1.03)％,(100.34 ± 5.19)％,(111.40 ± 3.69)％,(121.47 + 6.09)％,(129.95 ± 4.96)％,(121.81 ± 4.97)％,(111.00 ± 1.63)％;(10.35 ± 0.64)％,(35.23 ± 2.41)％,(110.30 ± 2.07)％,(113.66 ± 6.98)％,(120.36 ± 6.23)％,(133.40 ± 5.80)％,(126.06 ± 5.40)％,(115.62 ± 7.33)％; (6.19 ± 0.16)％,(18.44 ± 0.21)％,(120.83 ± 4.93)％,(123.77 ± 4.82)％,(129.09 ± 5.21)％,(140.44 + 4.18)％,(131.99 ± 7.00)％,(124.10 ± 3.68)％,respectively.The cell vitalities of 10-2,5 × 10-3 mol/L fluoride groups were significantly lower than that of the control group (all P ＜ 0.05).The cell vitality of 10-2 mol/L group was significantly lower than that of the 5 × 10-3 mol/L group (P ＜ 0.05).Doses of fluoride (10-2,5 × 10-3 mol/L) could inhibit the cell vitality and promote the apoptosis of chondrocytes in vitro with increasing doses and prolonged time.The cell vitalities of 10-3,10-4,10-5,10-6,10-7,10-8 mol/L of fluoride groups were significantly higher than that of the control group (except the 24 h 10-3 mol/L,P ＜ 0.05).Between 10-4 and 10-3 mol/L groups(the vitalities of 48 h and 72 h were higher,but not significantly); 10-5 and 10-4 mol/L groups (the vitality of 72 h was higher,but not significantly); 10-6 and 10-5 mol/L groups,the cell vitalities were significantly higher than that of the control group(all P ＜ 0.05).Between 10-7 and 10-6 mol/L groups,10-8 and 10-7 mol/L groups (the vitality of 72 h was lower,but not significantly),the cell vitalities were significantly lower than that of the control group(all P ＜ 0.05).Doses of fluoride(10-3-10-8 mol/L) could promote the cell vitality of chondrocytes in vitro with prolonged time.The optimal concentration for the promotion was 10-6 mol/L.The cells of the control group were characterized as regular morphology,the abnormal surface microvillis,abundant cytoplasm and mitochondrial,abundant and slightly expanded rough endoplasmic reticulums and low electron-dense materials.The cells of 10-6 mol/L fluoride group had the following changes,increased and swell mitochondrial,hypertrophy and expanded rough endoplasmic reticulums.The cells of 5 × 10-3 mol/L fluoride group had the following changes,decreased microvillis,invaginated cell membrane,pyknosis and apoptotic body.Conclusion Doses of fluoride (10-3-10-8 mol/L) can promote the proliferation of human chondrocytes cultured in vitro.Doses of fluoride (10-2,5 × 10-3 mol/L) can promote the apoptosis of human chondrocytes cultured in vitro.

Objective To evaluate the femur biomechanical changes of finite analysis with different femoral stem ex-tension implants in total knee arthroplasty (TKA). Methods The full-length femoral CT scan was performed in selected healthy volunteers. The femoral digital model was established with Mimics 10.0 and Geomagic Studio 10.0 software. The models of femoral prosthesis and stem extension implant were created by laser scanner. According to the common three hip loading modes (1 586 N, 1 690 N and 2 132 N), the maximum principal stress (MPS), the maximum principal elastic deforma-tion (MPES) and MPES distribution changes were recorded and analyzed by three-dimensional finite element analysis with ANSYS Workbench13.0 software. Results The MPS values before TKA were 98.54, 147.36 and 143.51 MPa respectively when values of femoral head loading were 1 586 N, 1 690 N and 2 132 N. With the increase in the length of the femoral pros-thesis extension rod, the MPS and MPES showed a decreasing trend. There was a positive correlation between free femur ra-tio (FFR) and MPES (P<0.05). The MPES distribution was gradually concentrated at the top point of femur stem extension implant with the increase in the length of the femoral prosthesis extension rod. Conclusion The values of MPS and MPES were gradually decreased with the increase in the length of the femoral stem extension implant. There was a positive linear correlation between FFR and MPES. The stress concentration was focused obviously at the top end of femoral stem extension implant with its length more than 120 mm.
