ABSTRACT

BACKGROUND@#There is limited information about thymosin α1 (Tα1) as adjuvant immunomodulatory therapy, either used alone or combined with other treatments, in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the effect of adjuvant Tα1 treatment on long-term survival in margin-free (R0)-resected stage IA-IIIA NSCLC patients.@*METHODS@#A total of 5746 patients with pathologic stage IA-IIIA NSCLC who underwent R0 resection were included. The patients were divided into the Tα1 group and the control group according to whether they received Tα1 or not. A propensity score matching (PSM) analysis was performed to reduce bias, resulting in 1027 pairs of patients.@*RESULTS@#After PSM, the baseline clinicopathological characteristics were similar between the two groups. The 5-year disease-free survival (DFS) and overall survival (OS) rates were significantly higher in the Tα1 group compared with the control group. The multivariable analysis showed that Tα1 treatment was independently associated with an improved prognosis. A longer duration of Tα1 treatment was associated with improved OS and DFS. The subgroup analyses showed that Tα1 therapy could improve the DFS and/or OS in all subgroups of age, sex, Charlson Comorbidity Index (CCI), smoking status, and pathological tumor-node-metastasis (TNM) stage, especially for patients with non-squamous cell NSCLC and without targeted therapy.@*CONCLUSION@#Tα1 as adjuvant immunomodulatory therapy can significantly improve DFS and OS in patients with NSCLC after R0 resection, except for patients with squamous cell carcinoma and those receiving targeted therapy. The duration of Tα1 treatment is recommended to be >24 months.

ABSTRACT

Objective:To investigate the effect of hyperbaric oxygen preconditioning on attention network functioning after chemotherapy.Methods:A total of 68 patients scheduled to receive chemotherapy were randomly divided into a hyperbaric oxygen preconditioning group (HBOPC, n=22), a hyperbaric oxygen sensitizing chemotherapy group (HBOSC, n=26), and a control group ( n=20). After 6 cycles of chemotherapy, the attention network test was administered to the patients in all three groups. Results:After the treatment, the average alerting efficiencies of the HBOPC and HBOSC groups were significantly higher than that of the control group. Their executive control was also significantly better. There were also significant differences in executive control between that the HBOPC and HBOSC groups, with the HBOPC group performed better. The post-treatment total reaction times of both the HBOPC and HBOSC groups were significantly shorter than that of the control group. That of the HBOPC group was significantly shorter than the HBOSC group′s total.Conclusions:Hyperbaric oxygen therapy can effectively reduce network function damage in terms of alerting and executive control. HBOPC protects executive control better than HBOSC.

ABSTRACT

Objective:To compare the clinical effects of Zero-profile (Zero-p) intervertebral fusion and titanium plate combined with cage fusion in treating symptomatic adjacent segment disease (ASD) after anterior cervical discectomy and fusion (ACDF).Methods:Retrospective analysis was performed on 26 patients who underwent ACDF and readmission due to concurrent symptomatic ASD from October 2014 to June 2019. There were 17 males and 9 females, aged 54.15±8.60 (range 41-68) years. The index level included C 2, 3 1 case, C 3, 4 3 cases, C 4,5 9 cases, C 5, 6 6 cases, C 6, 7 7 cases. Twelve cases underwent anterior cervical decompression with Zero-p intervertebral fusion and fixation (Zero-p group), while 14 cases underwent anterior cervical decompression with titanium plate combined with cage fusion and fixation (titanium plate group). The following parameters, including operative duration, intraoperative blood loss, Japanese Orthopaedic Association (JOA) score, visual analogue score (VAS), neck disability index (NDI), dysphagia Bazaz grade, bone graft fusion Eck grade, C 2-C 7 Cobb angle, and related complications, were compared between the two groups. Results:The operation was performed successfully in all the patients. The patients were followed up for averagely 33.38±21.26 (range 12-71) months. The operation duration was 95.83±5.47 (range 89-105) min in the Zero-p group, which was shorter than 121.28±8.24 (range 106-131) min in the titanium plate group. The Bazaz classification of dysphagia in the Zero-p group was superior to the titanium plate group at 1 month after operation ( W=126.00, P=0.022). Neither group had dysphagia 3 months after surgery. The JOA score increased from preoperative 9.50±1.31 to 14.33±0.78, and VAS decreased from 5.33±1.67 to 0.83±0.72 in the Zero-p group. The NDI decreased from 43.62%±9.31% to 14.99%±3.26%, and C 2-C 7 Cobb changed from 8.26°±2.92° to 14.80°±4.18° in the Zero-p group. The JOA score increased from preoperative 9.14±1.79 to 14.71±0.73, and VAS decreased from 5.43±1.55 to 1.43±0.76 in the titanium plate group. The NDI decreased from 43.76%±8.47% to 14.22%±4.59%, and C 2-C 7 Cobb changed from 5.53°±9.04° to 14.68°±6.89° in the titanium plate group. No complication, such as screw loosening or breakage or esophageal injury, occurred during the follow-up. Conclusion:Both methods can achieve good clinical effects in treating symptomatic ASD and can restore the physiological curvature of the cervical spine to a certain extent. Furthermore, the advantages of Zero-p intervertebral fusion include shorter operation duration, reducing soft tissue injury and less postoperative dysphagia.

ABSTRACT

Objective@#To explore the distribution of Traditional Chinese Medicine (TCM) syndrome types and their relationship with semen parameters in infertility male patients with varicocele (VC).@*METHODS@#Using Questionnaire on Clinical Symptoms of Varicocele-Caused Male Infertility, we made an investigation among 147 infertility male patients with VC, determined the types of their TCM syndromes, obtained their semen parameters, and analyzed the distribution of the TCM syndrome types and their correlation with semen parameters.@*RESULTS@#Of the TCM syndrome types identified, kidney deficiency and stagnated heat constituted the largest proportion (34.7%), and the mixed type accounted for a significantly higher percentage than the simple type (P < 0.05). The patients with kidney deficiency and stagnated heat, compared with those with other syndrome types, had a dramatically lower sperm concentration ([21.62 ± 9.25] vs [28.88 ± 12.92] ×10⁶/ml, P < 0.01), but a higher percentage of morphologically abnormal sperm ([98.33 ± 0.15]% vs [96.27 ± 0.18]%, P < 0.05) and DNA fragmentation index ([19.72 ± 3.17]% vs [10.96 ± 3.82]%, P < 0.01). No statistically significant differences were observed in the percentage of progressively motile sperm among different TCM syndrome types.@*CONCLUSIONS@#Kidney deficiency and stagnated heat is a main TCM syndrome type in infertility male patients with varicocele and correlated with sperm concentration, the percentage of morphologically abnormal sperm and DNA fragmentation index.

ABSTRACT

Non-alcoholic fatty liver disease (NAFLD) refers to the clinical syndrome characterized by excess deposition of fat in hepatocytes, which is due to the non-alcoholic or other definitive liver damage factors, which is closely related to insulin resistance and hereditary sensibility. Its typical process starts from simple fatty liver, then progresses to non-alcoholic steatohepatitis, and eventually develops into primary hepatocellular carcinoma (HCC). According to domestic and foreign literature reports in recent years, we make this review on the research status and progress of the pathogenesis of NAFLD-associated HCC.

ABSTRACT

Objective To explore the role of integrin αvβ3 in the promotion of the development of choroidal neovascularization (CNV) by SDF-1/CXCR4.Methods This study was divided into two parts in vitro and in vivo.As for the in vivo study,a CNV model was induced by laser on C57BL/6J mice,and then assigned into 4 groups:mice with solely CNV modeling as control group,with intravitreal injection of SDF-1 after immediate CNV modeling as SDF-1 group,with intravitreal injection of SDF-1 + CXCR4 inhibitor (AMD3100) after CNV modeling as SDF-1 + AMD3100 group,and mice with intravitreal injection of SDF-1 + αvβ3 inhibitor (SB273005) after modeling as SDF-1 + SB273005 group.CXCR4 and αvβ3 expression levels in laser-induced eyes were quantified by qRT-PCR at time points of day 1,3,5,7,10 and 14 after modeling,and immunofluorescence staining was applied to detect αvβ3 expression in regional CNV and its endothelial cells in the four groups.Finally,OCT was used to observe the height of retinal pigment epithelial (RPE) layers in CNV after treatment in the four groups.Moreover,in the experiment in vitro,Western blot was used to measure the expression of CXCR4 protein of RF/6A cells in normal control group,Si-CXCR4 knockdown group and Si-NC knockdown model group.Meanwhile,the expression of integrin subunit β3 protein was determined in the normal control group,SDF-1 group,SDF-1 + AMD3100group,SDF-1 + Si-NC group and SDF-1 + Si-CXCR4 group.Transwell assay was conducted to detect the migration ability of RF/6A cells in the normal control group,SDF-1group,SDF-1 +AMD3100 group,SDF-1 + SB273005 group.Results On the one hand,the study in vivo,qRT-PCR showed that the expression of CXCR4 and integrin subunit β3 mRNA was up-regulated at first,and then down-regulated with time passed after CNV induction,with the highest expression level of CXCR4 mRNA (4.263 ± 0.464) on day 3,and the peak expression of β3 mRNA (3.678 ±0.364) on day 7 after CNV modeling.The results of immunofluorescence staining showed that the β3 fluorescence intensity of SDF-1 group was significantly enhanced,and the ratio of β3/CD31 was also significantly increased,which both were significantly higher than those of the control group (P < 0.01).However,the β3 fluorescence intensity and β3/CD31 ratio of SDF-1 +AMD3100 group and SDF-1 + SB273005 group were significantly weakened and decreased,respectively (P <0.05).OCT showed that the elevation level of RPE layer inSDF-1 group was significantly higher than that in the control group [(135.503 ± 10.301) μm vs.(94.443 ± 12.156) μm](P<0.05).The height of RPE uplift in SDF-1 + AMD3100 group [(95.283 ±20.062) μm] and SDF-1 + SB273005 group [(99.807 ± 10.403) μm] was significantly decreased (P < 0.05).On the other hand,in experiment in vitro,Western blot showed that the expression levels of integrin β3 in SDF-1 group and SDF-1 + Si-NC group were significantly higher than those in the control group [(1.301 ± 0.043) and (1.273 ± 0.077) vs.(0.244 ± 0.069)] (P < 0.01).The levels of integrin subunit β3 protein in SDF-1 + si-CXCR4 group (0.322 ± 0.042) and SDF-1 + AMD3100 group (0.336 ± 0.077) were significantly down-regulated (P < 0.01).Transwell assay showed that the amount of migrating cells in SDF-1 group increased,which was significantly higher than that of the control group (P < 0.01),while the number of migrating cells in SDF-1 +AMD3100 group and SDF-1 + SB273005 group was significantly decreased.Conclusion Integrin αvβ3 can promote the development of CNV by mediating SDF-1/CXCR4 signaling in endothelial cells.

ABSTRACT

<p><b>BACKGROUND</b>According to the renal phospholipase A2 receptor (PLA2R) immunohistochemistry, idiopathic membranous nephropathy (iMN) could be categorized into PLA2R-associated and non-PLA2R-associated iMN. This study aimed to examine whether the non-PLA2R-associated iMN had any difference in clinical features compared with PLA2R-associated iMN.</p><p><b>METHODS</b>A total of 231 adult patients diagnosed as iMN were recruited to this retrospective study. Renal PLA2R expression was examined by immunofluorescence. Among these patients, 186 (80.5%) with complete baseline clinical data were used for further study. Urinary protein excretion, serum albumin, and creatinine were analyzed. For those patients with follow-up longer than 1 year, the relationship between PLA2R and response to immunosuppressants were analyzed. The t-test was used for parametric analysis and the Mann-Whitney U-test was used for nonparametric analysis. Categorical variables were described as frequencies or percentages, and the data were analyzed with Pearson's Chi-square test or Fisher's exact test.</p><p><b>RESULTS</b>Of the 231 iMN patients, 189 showed renal detectable PLA2R expression (81.8%). The baseline serum creatinine, serum albumin, and urine protein excretion were not significantly different between PLA2R-associated (n = 145) and non-PLA2R-associated iMN patients (n = 41). However, about 1/3 of the non-PLA2R-associated iMN had abnormal serological tests, significantly more common than PLA2R-associated iMN (31.7% vs. 8.3%, P = 0.000). The non-PLA2R-associated iMN had lower C4 levels compared with PLA2R-associated iMN (P = 0.004). The non-PLA2R-associated iMN patients also showed a better response to immunosuppressants (complete remission [CR] 42.9%; partial remission [PR] 14.3%) compared with PLA2R-associated iMN (CR 3.2%; PR 48.4%, P = 0.004) at the 3rd month.</p><p><b>CONCLUSIONS</b>There were no significant differences in serum creatinine, albumin, and urine protein excretion between PLA2R-associated and non-PLA2R-associated iMN, while the non-PLA2R-associated iMN patients showed more abnormal serological tests. The non-PLA2R-associated iMN seemed to respond more quickly to the immunosuppressive therapy compared with PLA2R-associated iMN.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical features, laboratory findings, diagnosis and treatment, and prognosis of children with systemic lupus erythematosus (SLE) accompanied by pulmonary hypertension (PH).</p><p><b>METHODS</b>The clinical symptoms, laboratory findings, echocardiographic features, SLE disease activity index, and treatment outcome of 15 hospitalized children with SLE accompanied by PH were retrospectively analyzed.</p><p><b>RESULTS</b>Among the 15 patients, the median interval from diagnosis of SLE to diagnosis of PH was 0.1 year (range: 0-6.5 years). Aside from PH-related symptoms, Raynaud's phenomenon was observed in 6 (40%) of the 15 patients. There was no significant difference in SLE disease activity (evaluated by complements 3 and 4 levels, erythrocyte sedimentation rate, and positive rate of anti-double-stranded DNA) between patients with mild-to-moderate PH and those with severe PH (P<0.05). As for treatment, 13 patients received immunosuppressive therapy with glucocorticoids, and among them 2 patients received PH-targeted therapy. During a median follow-up of 8.0 years (range: 0.5-18.1 years) since the diagnosis of PH, 2 deaths were noted with class III or IV cardiac function (World Health Organization), while the other patients were in a stable condition.</p><p><b>CONCLUSIONS</b>Raynaud's phenomenon is a common clinical manifestation in children with SLE accompanied by pulmonary hypertension (PH). PH severity is not significantly associated with SLE disease activity, and thus greater focus should be placed upon early screening of pulmonary arterial pressure in SLE patients. Early diagnosis and early treatment can improve the prognosis of children with SLE.</p>

ABSTRACT

Objective To establish a high performance liquid chromatography (HPLC) method for determining the content and dissolution of soluble guanylate cyclase(sGC) - 003 tablets. Methods Content and dissolution of sGC- 003 tablets were determined by HPLC. Phenomenex Luna C18 column(250 mm×4.6 mm, 5 μm) was used. The mobile phase was acetonitrile-water(40∶60, V/V), with a flow rate of 1.0 ml/min, and the detection wavelength was set at 214 nm. The column temperature was 40 ℃ and the injection volume was 20 μl(injection volume of dissolution was 80 μl). Dissolution of sGC-003 tablets was determined by the second method described in Chinese Pharmacopoeia(ChP) 2015. 900 ml of pH 4.5 acetic acid buffer, pH 6.8 phosphoric acid buffer and water were used as dissolution media at the rotation speeds of 50 and 75 r/min to select the dissolution condition. Results This method had high specificity. The average recovery was about 99.58%(RSD=0.75%, n=9). And the working solution was stable within 12 h. The calibration curves were had good linearity (R2=1) within the concentration range of 0.25-50 μg/ml. The method of dissolution tests for sGC-003 tablets was established that 900 ml pH 6.8 phosphoric acid buffer was used as dissolution medium and paddle rotation speed was 50 r/min. The dissolution would be 80% at 30 min. Conclusion The dissolution condition can be used to determine the dissolution of sGC-003 tablets. The HPLC method is convenient, fast, sensitive and accurate in determining the content and dissolution of sGC-003 tablets.

ABSTRACT

<p><b>OBJECTIVE</b>To verify the role of the newly identified mitotic regulator candidate pre-mRNA processing factor 19 (Prp19) in mitosis and to clarify its underlying mechanism.</p><p><b>METHODS</b>FACS analyses with propidium iodide (PI) staining were performed to evaluate the effect of Prp19 knockdown on cell cycle distribution. To further clarify the role of Prp19 in mitosis, the effect of Prp19 depletion was monitored by time-lapse imaging of HeLa/GFP-H2B cells. Cold treatment experiment was used to examine the effect of Prp19 knockdown on the attachment of microtubules and kinetochores. To evaluate the effect of Prp19 knockdown on cell apoptosis, the control and Prp19-knockdown cells were analyzed by FACS with annexin V-FITC/-PI double staining. Furthermore, Western blot analysis of cleaved caspase-3 and PARP was also performed.</p><p><b>RESULTS</b>Prp19 knockdown causesd mitotic arrest. Time-lapse imaging analysis showed that depletion of Prp19 in HeLa cells results in prometaphase arrest and chromosome misalignment. Cold treatment experiment showed that attachment between kinetochore and microtubule was impaired by Prp19 knockdown. Moreover, the depletion of Prp19 leaded to cell apoptosis in cancer cells.</p><p><b>CONCLUSION</b>Prp19 is a key regulator of mitotic progression, and its inhibition may provide a new strategy for anti-cancer therapy.</p>

ABSTRACT

Objective To explore the effect of LPLD (laparoscopic peritoneal lavage and drainage ) on SAP (severe acute pancreatitis), and to compare its effect with that of non- LPLD (conservative medical management). Methods We collected data from 87 consecutive patients with SAP, from January 2009 to May 2014, including LPLD group (n = 46) and non-LPLD group (n = 41). LPLD was performed in the 1st and 2nd week after the disease onset in LPDP group and other treatment in LPDP group was the same as that in non-LPLD group. Data were comparatively analyzed in two groups about the length of hospital stay, ICU stay, cure rate, incidence of complications and in-hospital mortality. Results In LPLD group, hospital stay, and ICU stay were shorter while cure rate was higher than those in non-LPLD group , and the difference was statistically significant (P 0.05). Conclusion Compared with non-LPLD, LPLD is effective in short outcome, which is a promising treatment for SAP.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluateclinical features, treatment and outcomes of patients diagnosed with primary breast diffuse large B-cell lymphoma(DLBCL).</p><p><b>METHODS</b>Clinical data were analyzed for all patients diagnosed with primary breast DLBCL(n=21). Kaplan-Meier method was used to estimate 5- year overall survival(OS)rate, and the difference was compared by Log- rank test.</p><p><b>RESULTS</b>The 21 cases of patients with primary breast DLBCL were all female with median age at diagnosis as 48 years (range 21-64 years). 13 patients had International Prognostic Index(IPI)of 0, 6 IPI 1, and 2 IPI 2. The 5- year OS rates of CHOP/R- CHOP and R±DICE after R±EPOCH groups were 40.0% and 72.2% , respectively(P=0.035). The central nervous system relapse rate of CHOP/R-CHOP and R±DICE after R± EPOCH groups were 16.7% and 6.7%(P=0.500), respectively. The 5- year OS rates of patients with primary breast DLBCL staging Ⅱ E-Ⅲ E and Ⅰ E were 21.4% and 83.3% , respectively(P=0.025).</p><p><b>CONCLUSION</b>Primary breast DLBCL was rare.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical features and gene mutations of 4 Chinese children with Dent disease.</p><p><b>METHODS</b>The clinical and laboratory data of 4 children with Dent disease were analyzed retrospectively. Genetic testing of the 4 cases was carried out.</p><p><b>RESULTS</b>All of 4 cases were boys. The first impression of Cases 1-3 was Fanconi syndrome. Proteinuria was presented as the first impression in Case 4. All 4 boys presented with low-molecular weight proteinuria (LMWP) and hypercalciuria, including 3 cases with hematuria, 1 case with kidney stones, 2 cases with nephrocalcinosis, 3 cases with hypophosphatemia, and 3 cases with rickets. Mutations of the CLCN5 gene were revealed in three patients (Cases 1, 2 and 4), including exon 6-7del, c.785_787de l(p.263del Leu) and c.1039 C>T (p.Arg347Term). The first two gene mutations had never reported before.</p><p><b>CONCLUSIONS</b>Urine protein electrophoresis should be carried out for patients with proteinuria. Dent disease should be taken into consideration when patients with Fanconi syndrome have hypercalciuria, nephrocalcinosis or kindey stones. Genetic analyses are needed for a definite diagnosis.</p>

ABSTRACT

This study aimed to examine the optimal conditions of laser-induced interstitial thermotherapy (LITT) via a single-needle delivery system, and the ablation-related pathological and ultrasonic changes. Ultrasound (US)-guided LITT (EchoLaser system) was performed at the output power of 2-4 Wattage (W) for 1-10 min in ex vivo bovine liver. Based on the results of the ex vivo study, the output power of 3 and 4 W with different durations was applied to in vivo rabbit livers (n=24), and VX2 tumors implanted in the hind limbs of rabbits (n=24). The ablation area was histologically determined by hematoxylin-eosin (HE) staining. Traditional US and contrast enhanced ultrasound (CEUS) were used to evaluate the treatment outcomes. The results showed: (1) In the bovine liver, ablation disruption was grossly seen, including a strip-like ablation crater, a carbonization zone anteriorly along the fiber tip, and a surrounding gray-white coagulation zone. The coagulation area, 1.2 cm in length and 1.0 cm in width, was formed in the bovine liver subjected to the ablation at 3 W for 5 min and 4 W for 4 min, and it extended slightly with the ablation time. (2) In the rabbit liver, after LITT at 3 W for 3 min and more, the coagulation area with length greater than or equal to 1.2 cm, and width greater than or equal to 1.0 cm, was found. Similar coagulation area was seen in the implanted VX2 carcinoma at 3 W for 5 min. (3) Gross examination of the liver and carcinoma showed three distinct regions: ablation crater/carbonization, coagulation and congestion distributed from the center outwards. (4) Microscopy revealed four zones after LITT, including ablation crater/carbonization, coagulation, edema and congestion from the center outwards. A large area with coagulative necrosis was observed around a vessel in the peripheral area with edema and hyperemia. (5) The size of coagulation was consistent well to the CEUS findings. It was concluded that EchoLaser system at low power can produce a coagulation area larger than 1.0 cm×1.0 cm during a short time period. The real-time US imaging can be used to effectively guide and assess the treatment.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of Bushengzhuyang Fang (Yangjing Capsule, YJC) on penile erectile function and its action mechanisms in rats.</p><p><b>METHODS</b>Fifty-six male SD rats were randomly divided into seven groups of equal number: blank control, daidzein, daidzein + testosterone, daidzein + sildenafil, daidzein + low-dose YJC, daidzein + medium-dose YJC, and daidzein + high-dose YJC. The rats in the blank control group were treated intragastrically with normal saline and those in the other groups with daidzein at the dose of 100 mg per kg per day for 30 days. Then the last five groups received additionally testosterone (4 mg per kg per day), sildenafil (2.5 mg per kg per day), low-dose YJC, (0.315 mg per kg per day), medium-dose YJC (0.63 mg per kg per day), and high-dose YJC (1. 26 mg per kg per day), respectively. At 0, 30 and 60 days of treatment, we observed the apomorphine-induced spontaneous erectile response and pathological changes in the corpus cavernosum of the rats, recorded the number of penile erection and erectile incubation period, and determined the serum levels of testosterone (T) and luteinizing hormone (LH).</p><p><b>RESULTS</b>At 30 days of treatment, the number of apomorphine-induced erections was decreased, the erectile incubation period prolonged, and the serum levels of T and LH reduced remarkably in all groups of rats (P < 0.05). Compared with the findings at 30 days, the number of penile erections was significantly decreased at 60 days in the daidzein group (1.39 ± 0.42 vs 2.67 ± 0.33, P < 0.05) and daidzein + low-dose YJC group (1.33 ± 0.49 vs 2.83 ± 0.61, P < 0.05); the erectile incubation period was markedly ex- tended ([16.33 ± 3.11] vs [8.50 ± 0.93] min and [15.50 ± 3.21] vs [8.63 ± 1.54] min, P < 0.05); and the serum levels of T ([5.34 ± 0.89] vs [1.24 ± 0.30] ng/ml and [5.28 ± 1.12] vs [2.07 ± 0.76] ng/ml, P < 0.05) and LH ([3.62 ± 0.37] vs [2.09 ± 0.12] ng/ml and [3.79 ± 0.28] vs [2.17 ± 0.33] ng/ml, P < 0.05) were significantly reduced in the daidzein and daidzein + low-dose YJC groups, respectively. Pathological examination revealed slightly decreased cavernous sinuses and blood vessels in the corpus cavernosum of the rats in the daidzein + testosterone, daidzein + sildenafil, daidzein + medium-dose YJC, and daidzein + high-dose YJC groups as compared with those in the blank control group.</p><p><b>CONCLUSION</b>High-dose Yangjing Capsule is efficacious for the recovery of erectile function in rats, especially for phytoestrogen-induced erectile dysfunction.</p>

ABSTRACT

This study was purposed to observe the influence of umbilical cord mesenchymal stem cells (UC-MSC) on the peripheral blood CD4(+)CD25(+)regulatory T cells (Treg), Th17 cells and neutrophils in rats with collagen type II-induced arthritis(CIA), and to explore the regulating effect of UC-MSC transplantation on immunocyte subgroup. The rats wee divided into 3 groups: CIA group (model group), UC-MSC treated group and blank control group. The CIA rats were injected with UC-MSC via tail vein. The percentage of CD4(+)CD25(+) cells in peripheral blood and the expression of NCD11b on neutrophil surface in CIA rates was detected by flow cytometry (FCM), and the serum interleukin-17 (IL-17) was observed by enzyme-linked immunosorbent assay (ELISA). The results showed that the mean fluorescence intensity(MFI) of NCD11b and the level of IL-17 in the model group were significantly higher than those in the blank control group, and the ratio of CD4(+)CD25(+) cells were significantly lower (P < 0.05). The MIF of NCD11b and the level of IL-17 in the UC-MSC treated group were significantly lower than that in the model group (P < 0.05), while the proportion of CD4(+)CD25(+) Treg increased (P < 0.05). Since the fifth week, the above indicators in the UC-MSC group have almostly approached the control group. It is concluded that the UC-MSC can increase peripheral blood Treg proportion in CIA rat, inhibit the secretion of Th17 and the activity of neutrophils, reduce the immune inflammation reaction, decrease the release of proinflammatory factor, and induce immune reconstruction.
