ABSTRACT

Objective:To investigate the effect of bedside high-flow continuous blood purification (CBP) combined with Xuebijing in the treatment of severe sepsis (SS) and the influence on the patient′s coagulation-fibrinolysis index, immunity index and expression of peripheral blood Toll-like receptor 4 (TLR4).Methods:Ninety-three patients with SS who were admitted and treated in the Lianyungang First People′s Hospitalfrom January 2017 to October 2019 were selected. They were divided into the combined group (51 cases, treatment with bedside high-flow CBP and Xuebijing injection based on bundle therapy) and the control group (42 cases, treatment with Xuebijing injection based on bundle therapy). The changes in coagulation and fibrinolysis index, immunity index, biochemical index such as TLR4 before treatment and after 1 week of treatment were compared between the two groups. The incidences of complications in both groups were statistically analyzed, and the discharge time from ICU, mechanical ventilation time and 28-day mortality were recorded.Results:After 1 week of treatment, the levels of prothrombin time (PT) and activated partial thromboplastin time (APTT) in the two groups were shortened, D-dimer (D-D) and fibrinogen (FIB) were decreased ( P<0.05); and the levels of PT and APTT in the combined group were shorter than those in the control group, the levels of DD and FIB were lower than those in the control group, there were statistical differences ( P<0.05). After 1 week of treatment, the levels of CD 4+ and CD 4+/CD 8+ ratio in both groups were increased ( P<0.05), and the levels of CD 4+ and CD 4+/CD 8+ ratio in the combined group were higher than those in the control group ( P<0.05). After 1 week of treatment, the levels of TLR4, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC), blood lactate (Lac), blood urea nitrogen (BUN) and serum creatinine (Scr) in both groups were decreased ( P<0.05), meanwhile, the above indexes in the combined group were lower than those in the control group ( P<0.05). The incidence of multiple organ failure and the 28-day mortality rate in the combined group were lower than those in the control group: 3.92%(2/51) vs. 19.05%(8/42), 13.73%(7/51) vs. 30.95%(13/42), there were statistical differences ( P<0.05). The discharge time from ICU and mechanical ventilation time in the combined group were shorter than those in the control group: (12.35 ± 2.14) d vs. (14.17 ± 3.36) d, (7.12 ± 2.23) d vs. (8.51 ± 2.39) d, there were statistical differences ( P<0.05). Conclusions:Bedside high-flow CBP combined with Xuebijing injection in the treatment of SS can improve the patient′s condition, regulate the balance of coagulation and fibrinolysis, avoide the activation of coagulation, inhibite inflammatory response, reduce the expression of TLR4 in peripheral blood, improve immune function, protecte kidney function and promotethe patient′s recovery.

ABSTRACT

Objective Bushen-Qingxin decoction combined conjugated estrogen tablets of modulation perimenopausal women osteoporosis patients, explore the impact of bone mineral density and bone metabolic markers. Methods A total of 160 female patients were recruited in our hospital by the random number table method, and were divided into the control group 80 cases and the observation group 80 cases. The control group was treated with standard dose of conjugated estrogen tablets, while the observation group was treated with Bushen Qingxin decoction on the basis of the control group. Both groups were treated 3 period with 28 days per period. The enzyme-linked immunity analyzer was used to detect serum bone-specific alkaline phosphatase (BALP), C-terminal cross linked peptide (CTX-Ⅰ), tartrate resistant acid phosphatase -5b (TRACP-5b) level, and the dual-energy X-ray absorptiometry measurement method was used to detect bone mineral density values. The clinical curative effect was compared between two groups. Results The total effective rate of the observation group was 91.3%, while the control group was 78.8%, which showed the difference was statistically significant (χ 2=3.971, P=3.971). After treatment, the serum BALP levels (88.55 ± 10.33 U/L vs. 80.47 ± 8.67 U/L, t=5.399) of the observation group were significantly higher than this of the control group (P<0.01). After treatment, the serum TRACP-5b (501.31 ± 35.77 pg/L vs. 538.51 ± 37.69 pg/L, t=6.498), CTX- (130.09 ±Ⅰ17.55 ng/ml vs. 164.71 ± 19.45 ng/ml, t=11.928) of the observation group were significantly lower than those of the control group (P<0.01). After treatment, the bone mineral density of the observation group rose up from the baseline (t=3.396, P=0.010). Conclusions The Bushen-Qingxin decoction combined conjugated estrogen tablets can increase on women in the menopausal transition of osteoporosis in patients with bone mineral density values and serum BALP levels, reduce serum TRACP-5b, CTX-Ⅰ level.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the phonological characteristics and rehabilitation training of abnormal velar in patients with functional articulation disorders (FAD).</p><p><b>METHODS</b>Eighty-seven patients with FAD were observed of the phonological characteristics of velar. Seventy-two patients with abnormal velar accepted speech training. The correlation and simple linear regression analysis were carried out on abnormal velar articulation and age.</p><p><b>RESULTS</b>The articulation disorder of /g/ mainly showed replacement by /d/, /b/ or omission. /k/ mainly showed replacement by /d/, /t/, /g/, /p/, /b/. /h/ mainly showed replacement by /g/, /f/, /p/, /b/ or omission. The common erroneous articulation forms of /g/, /k/, /h/ were fronting of tongue and replacement by bilabial consonants. When velar combined with vowels contained /a/ and /e/, the main error was fronting of tongue. When velar combined with vowels contained /u/, the errors trended to be replacement by bilabial consonants. After 3 to 10 times of speech training, the number of erroneous words decreased to (6.24±2.61) from (40.28±6.08) before the speech training was established, the difference was statistically significant (Z=-7.379, P=0.000). The number of erroneous words was negatively correlated with age (r=-0.691, P=0.000). The result of simple linear regression analysis showed that the determination coefficient was 0.472.</p><p><b>CONCLUSIONS</b>The articulation disorder of velar mainly shows replacement, varies with the vowels. The targeted rehabilitation training hereby established is significantly effective. Age plays an important role in the outcome of velar.</p>

ABSTRACT

Objective To explore the role of dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) in the tubulointerstitial lesions of immune-mediated nephrotoxic nephritis (NTN) and the intervention regulation by anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb). Methods WKY rats were randomly divided into control,NTN and PsL-EGFmAb-treated groups. The mrs in NTN group were injected with 1 ml nephrotoxic rabbit serum per kilogram of rat body weight; the ones in PsL-EGFmAb-treated group were injected with 2 mg PsL-EGFmAb per kilogram of rat body weight simultaneously and 2 h later after nephrotoxic rabbit serum injection; and those in control group were injected with equal volume of 0.9% saline. Renal function and pathology were observed at day 4, 7 and 14 after the induction of NTN. Distribution of DC-SIGN + dendritic cells (DCs) in renal tissues was measured by immunofluorescence. Real-time PCR was performed to examine the expression of P-selectin,RANTES, TNF-α, IL-10, IFN-γ and IL-4. Expression of MHC Ⅱ , CD80 and DC-SIGN on dendritic cells was analyzed by flow cytometry. Transendothelial migration was used to detect the ability of DCs migration. DCs ability to activate T cells was determined by mixed lymphocyte reaction (MLR). ELISA was used to detect the concentration of IFN-γ and IL-4 in the supernatant of MLR. Results At day 4, immature DC-SIGN+ DCs infiltrated the rat renal tubulointerstium of NTN group, matured at day 14, and enhanced the ability to migrate and activate T cells. The distribution of DC-SIGN + DCs was significantly related to the form of crescent, tubulointerstial lesions and renal function. In addition, expression of chemokine RANTES and proinflammatory cytokine TNF-α continuously augmented since day 4, while anti-inflammatory eytokine IL-10 decreased after markedly increased at day 4. At day 14, IFN-γ/IL-4 mRNA increased, which was obviously related to DCs maturation. The intervention of PsL-EGFmAb supressed the expression of DC-SIGN and CD80 on DCs, depressed DCs maturation, migration and ability to activate T cells,down-regulated proinflammatory cytokines and up-regulated anti-inflammatory cytokines in kidney,and thus regulated Th1/Th2 bias. At the same time, kidneys showed the decrease of crescents,improvement of tnbulointerstium damage and renal function. Conclusions DC-SIGN may mediate DCs tubulointerstitial infiltration. It may be also a potent regulator of local immune reaction imbalance and pathology of tubulointerstium. PsL-EGFmAb may depress DCs migration and downregulate DCs maturation and function through DC-SIGN, and thus having a role in prevention and treatment.

ABSTRACT

Objective To explore the inhibition effects of epidermal growth factor receptor (EGFR) antagonist monoclonal antibody cetuximab (C225) on breast cancer stem cells in human breast cancer cell line MCF-7.Methods The effects of C225 on the proliferation of breast cancer cell line MCF-7 were detected by MTT assay. MCF-7 cells were cultured to generate primary mammospheres, and were divided into control group, C225 group, epidermal growth factor (EGF) group and EGF + C225 group according to whether or not the culture media contained exogenous EGF and C225.Thirteen days after culture, the volume and number of mammospheres of these four groups were observed, and mammosphere-forming efficiency ( MFE) was calculated. The percentages of CD44~+ CD24~- cells in mammospheres of these four groups and in routinely cultured MCF-7 cells were determined by flow cytometry. Results The inhibition rate on MCF-7 cells increased with the concentration of C225.Compared with control group, the volume of mammospheres in C225 group significantly decreased, and MFE and percentages of CD44~+ CD24~- cells in mammospheres significantly decreased [(0.61 ±0.04)% vs (1.44±0.09)%, P<0.01; (3.50±0.29)% vs (9.07 ±0.52) % , P<0.01]. Compared with EGF group, the volume of mammospheres in EGF + C225 group significantly decreased, and MFE and percentages of CD44~+ CD24~- cells in mammospheres significantly decreased [ (0.68 ± 0.04) % vs (1.61 ± 0.05) % , P < 0.01; (4.00 ± 0.58) % vs (10.47 ± 0.79) % , P < 0.01]. The percentage of CD44~+ CD24~- cells in routinely cultured MCF-7 cells was (2.03 ±0.15) % , and was significantly different from those in EGF group and control group (P < 0.01). There was no significant difference in volume of mammospheres, MFE and percentage of CD44~+ CD24~- cells in mammospheres between EGF group and control group (P >0.05). Conclusion C225 has significant inhibition effects on CD44~+ CD24~- cells in MCF cells.
