ABSTRACT

Objective:To evaluate the clinical efficacy and safety of Longmu Zhuanggu granule for the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency. Method:This multicenter stratified, block-randomized, double-blind, double-dummy, positive drug (pidotimod granule) parallel controlled, and non-inferiority trail intended to included 240 children patients and divided them into the experimental group (<italic>n</italic>=120) and the control group (<italic>n</italic>=120) at the ratio of 1∶1. Patients in both groups were treated for eight successive weeks and followed up for 12 months. The cure rates, numbers of respiratory infections, average courses of disease, curative effects of traditional Chinese medicine (TCM) syndrome, curative effects of individual symptoms, curative effects of immune indexes, and safety indexes between the two groups were observed and compared. Result:A total of 237 subjects were collected from 10 research centers, including 119 cases in the control group and 118 in the experimental group. There were 236 cases enrolled into the full analysis set (FAS), 210 into the per-protocol set (PPS), and 236 into the safety set (SS). The baseline data of the two groups were not significantly different from each other, indicating that they were comparable. The cure rates of the experimental group and control group were 75.21% (88/117) and 73.95%(88/119), respectively, with the 95% confidence interval (CI) of difference between the two groups being 1.26% (-9.85%,12.37%) for FAS and 3.81% (-6.28%,13.90%) for PPS. The 95% CI fell within the 10% non-inferiority margin, implying that non-infertility test of the cure rate in the treatment of endpoint disease was valid, and the conclusions of FAS and PPS analysis were consistent. There was no significant difference in the number or course of upper respiratory infection, bronchitis, and pneumonia. The difference in curative effects of TCM syndrome between the two groups after four weeks of treatment was not remarkable. After eight weeks of treatment, the total effective rate of the experimental group was 84.62%(99/117), statistically higher than 78.15%(93/119) of the control group(<italic>χ</italic><sup>2</sup>=-3.26,<italic>P</italic><0.05). There were no significant differences in the disappearance rates of individual symptoms between the two groups after four weeks of treatment. After eight weeks of treatment, the experimental group and control group exhibited the disappearance rates of 67.50%(54/80) and 47.37%(36/76) for shortness of breath and laziness to speak, 75.00%(54/72) and 53.33%(40/75) for poor appetite, 54.55%(60/110) and 37.84%(42/111) for hyperhidrosis, respectively, with obviously better outcomes observed in the experimental group (<italic>P</italic><0.05,<italic>P</italic><0.01). The inter-group comparison revealed significant differences in immune indexes after eight weeks of treatment. As demonstrated by comparison with the situations before treatment, IgA, IgG, IgM, and CD4 did not change significantly after treatment. Except for CD8 in the experimental group (<italic>P</italic><0.05), there was no significant difference in other immune indexes before and after treatment There was no significant difference in the incidence of adverse reactions. Conclusion:Longmu Zhuanggu granule is not inferior to pidomod granule in the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency, and it exhibits good safety, implying its promising clinical application value.

ABSTRACT

Two new polypeptides were isolated and purified from the extract of deer bone (constitutive part of Cucumis and Cervus polypeptide injection) by various column chromatography including C₄ 300Å and Sephadex G-50, as well as semipreparative HPLC. Their N-terminal amino acid sequences were identified by De Novo sequencing on the basis of MALDI-TOF-MS data and Explorer™ software. The N-terminal amino acid sequences of polypeptides were identified as NH₂-Gly-Pro-Val-Gly-Pro-Thr-Gly-Pro-Val-Gly-Ala-Ala-Gly-Pro-Ser-Gly-Pro-Asp (Mei18 peptide, 1) and NH₂-Ala-Gly-Pro-Ala-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Leu-Gly-Pro-Pro-Asp-Ser-Try-Asp (Mei23 peptide, 2), respectively. Mei18 and Mei 23 peptides are new polypeptides.

ABSTRACT

<p><b>Background</b>The co-existence of myasthenia gravis (MG) and thymoma makes the surgical treatment more complicated and adjuvant radiation more controversial. The aim of this study was to investigate adjuvant radiotherapy for thymoma with MG after extended thymectomy.</p><p><b>Methods</b>A total of 181 patients with both MG and thymoma were recruited between 2003 and 2014 at Tongren Hospital, China. Among all the patients, 157 patients received radiation therapy after surgery (Group A); whereas the other 24 patients did not receive radiation therapy (Group B). According to the time that patients started mediastinal radiation therapy, we subdivided the 157 patients in Group A into subgroups (1-month subgroup, n = 98; 2-month subgroup, n = 7; and 3-month subgroup, n = 52). We then compared the effect of the mediastinal radiation therapy across these different groups using the survival rate, the rate of postoperative myasthenic crisis, and the complete stable remission (CSR) rate as the primary endpoints.</p><p><b>Results</b>There was a significant difference in the occurrence of postoperative myasthenic crisis between 1-month subgroup and Group B (χ = 4.631, P = 0.031). The rates of reaching CSR were 32.6% in 1-month subgroup, 25% in 3-month subgroup, and 22.7% in Group B, respectively. The overall survival rates of 1-month subgroup, 3-month subgroup, and Group B were 88.8%, 83.3%, and 77.3%, respectively. Analysis on the Kaplan-Meier survival curves demonstrated that within 8 years after surgery, there was no significant difference in aspects of overall survival and disease-free survival between 1-month subgroup and Group B, and between 3-month subgroup and Group B; over 8 years after surgery, the disease-free survival rates in 1-month subgroup, 3-month subgroup and Group B were 79.4%, 70.6%, and 55.3%, respectively.</p><p><b>Conclusions</b>Adjuvant radiation within 1 month after extended thymectomy may be helpful in controlling postoperative MG, such as decreasing the possibility of postoperative myasthenic crisis, and raising cumulative probabilities of reaching CSR.</p>

ABSTRACT

<p><b>OBJECTIVE</b>We aim to explore the potential association between serum gamma-glutamyl transferase levels and functional outcome after aneurysmal subarachnoid hemorrhage in a Chinese population.</p><p><b>METHODS</b>A total of 386 aneurysmal subarachnoid hemorrhage patients were included in the study from September 2007 to February 2015. Baseline serum gamma-glutamyl transferase levels and 6-month follow-up functional outcomes were determined. A poor outcome was defined as a modified ranking scale score of ⋝ 3. The multivariable logistic model was used to analyze the relationship between serum gamma-glutamyl transferase and clinical outcomes after aneurysmal subarachnoid hemorrhage.</p><p><b>RESULTS</b>The adjusted poor outcome rates of patients with gamma-glutamyl transferase levels of < 30 U/L, 30-50 U/L and ⋝ 50 U/L were 16.7%, 19.6%, and 34.4%, respectively (P < 0.01). The age-sex and multivariable adjusted odds ratios (95% confidence intervals) of poor prognosis comparing the top group (⋝ 50 U/L) with the lowest group (< 30 U/L) were 5.76 (2.74-12.13), 6.64 (2.05-21.52), and 6.36 (1.92-21.02). A significant linear trend existed between gamma-glutamyl transferase level and aneurysmal subarachnoid hemorrhage prognosis. This association was also observed among nondrinkers.</p><p><b>CONCLUSION</b>Patients with higher gamma-glutamyl transferase levels were more likely to have a poor prognosis. Serum gamma-glutamyl transferase can be considered to be an independent predictor of functional outcomes after aneurysmal subarachnoid hemorrhage.</p>

ABSTRACT

Nitrogen nutrition divided into concentrations and forms for Epimedium pseudowushanense was studied under hydroponic conditions. There were 7 nitrogen concentrations treatments(N0-N6)which nitrogen concentration was 0, 2.5, 5.0, 7.5, 10.0, 13.0 mmol•L⁻¹, respectively, and 5 nitrogen forms and proportions treatments (T1-T5) which NO3-N/NH4-N was 5∶0, 4∶1, 2.5∶2.5, 1∶4, 0∶5 respectively, the total nitrogen applied was 5 mmol•L⁻¹. The results showed that along with the increase of nitrogen concentration, biomass (dry weight) and leaf dry weight increased, which in N5 treatment was 29%, 23% higher than those in N0 and 36%, 23% higher than those in N4 respectively, but not significantly different from N6 treatment. Roots and stem dry weights did not change significantly. Pn and the contents of photosynthetic pigments were higher in N3-N5 treatments. Epimedin A, B, C, icariin and total flavonoids contents were the lowest in N3 treatment, suddenly increase in N4 treatment and only a little change between N4-N6 treatments. N5 treatment with the highest epimedin C content was 131% higher than N3 treatment with the lowest epimedin C content (P<0.05). While in the nitrogen forms and proportions treatments, biomass, leaf and stem dry weights were the highest in T3 treatment and lower in T1 and T5 treatments, without significance between T1 and T5 treatments. These indicators in T3 treatment were more than 30% higher than those in T1 treatment. The impact of nitrogen concentrations was greater than nitrogen forms on flavonoids. epmedin C content was the highest in T1 treatment, only 5%-8% higher than that in T2-T5 treatments (no significance between 4 treatments). Epimedin A, B, icariin and total flavonoids contents were higher in T1 treatment, the lowest in T2 treatment, those in T1 treatment was 41%, 62% and 27% higher than T2 treatment respectively (P<0.05). In a conclusion, E. pseudowushanense is a high nitrogen tolerant plant, 10.0 mmol•L⁻¹ was the boundary point between growing general to well and the optimal nitrogen concentration for it was 10.0-13.0 mmol•L⁻¹. Besides, it prefers to grow in NO-3 plus NH+4 and the optimal proportion was 2.5∶2.5.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the incidence, predisposing factors and therapeutic modalities of acute colonic pseudo-obstruction (ACPO) in patients after total hip arthroplasties (THA) and total knee arthroplasties (TKA).</p><p><b>METHODS</b>From January 2006 to December 2009, 12 patients with ACPO after THA and TKA operation were investigated retrospectively,who were viewed as the ACPO group. There were 10 males and 2 females with an average age of (78 +/- 12) years in the ACPO group. Other 853 patients without ACPO after THA and TKA operation were viewed as the control group treated at the same period. The incidence of ACPO was calculated. The clinical data were collected and compared between the two groups including patient age, gender, procedure, anesthetic class, clinical presentation, radiographic findings, duration from index surgery to diagnosis of ACPO, treatment, postoperative mobilization time, and length of hospital stay.</p><p><b>RESULTS</b>The incidence of ACPO was 1.4%. The incidence of primary THA (1.3%) was higher than that of primary TKA (0.4%); the incidence of hip and knee revisions (5.0%) was higher than that of primary THA and TKA (1.0%); there was no difference in incidence between hip revisions (5.5%) and knee revisions (4.0%). The mean age was (78 +/- 12) years old in ACPO group and (71 +/- 13) in the control group. The male/female ratio was 5:1 in ACPO group and 2:3 in control group. There were statistical differences in mean age and gender ratio between the two groups. No association was found with respect to anesthetic class. On average, ACPO occurred at 2.5 days after index surgery. The abdominal distention occurred in all 12 cases, nausea or vomiting in 8 cases and abdominal pain in 3 cases. Radiographically cecal dilation occurred in all cases and intestinal dilation in 3 cases. All patients initially were treated conservatively with immediate cessation of oral intake,a nasogastric tube and oral mineral oil. Three patients received a rectal tube. Only 1 patient required endoscopic decompression. There were no deaths after ACPO in the series. Mean mobilization time after surgery averaged (5.0 +/- 2.2) days in ACPO group compared with (2.5 +/- 1.1) days in the control group. Mean hospital stay averaged (16.5 +/- 6.4) days in ACPO group compared with (10.5 +/- 4.5) days in the control group. There were statistical differences in mean mobilization time after surgery and mean hospital stay between two groups.</p><p><b>CONCLUSION</b>ACPO mainly happened in old male patients. The majority cases response to conservative treatment and their prognoses are good. But ACPO will delay mobilization time after surgery and increase hospital stay.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the inhibitory effect of 4-chlorobenzoyl berbamine (BBD9) on imatinib-resistant cell line K562 (K562/IR) in vitro and in vivo and explore the mechanisms.</p><p><b>METHODS</b>The IC50 of BBD9 and berbamine (BBM) was determined by MTT assay. The expressions of p210(Bcr-Abl), IKKa, cytoplasmic and nuclear NF-κBp65 were determined using Western blotting in K562/IR cells following a 48-h exposure to 0.5 µg/ml BBD9 or 8 µg/ml BBM. Flow cytometry was used to analyze the cell viability, apoptosis and necrosis; Western blotting was employed to determine the expressions of PARP, caspase-3, caspase-9 and LC3II in K562/IR cells exposed to different concentrations of BBD9 for 48 h. In nude mouse models bearing K562/IR cell xenograft, the tumor weight, tumor regression, and body weight changes of the mice were measured after treatments with 15 mg/kg and 30 mg/kg BBD9 and 100 mg/kg imatinib.</p><p><b>RESULTS</b>The IC50 of BBD9 and BBM was 0.73 µg/ml and 5.43 µg/ml, respectively. In K562/IR cell cultures, the expressions of p210(Bcr-Abl), IKKa and nuclear NF-κB p65 were all decreased following BBD9 and BBM treatments, but BBD9 produced more potent effect; cytoplasmic NF-κB p65 showed no obvious changes after the treatments. The cell apoptosis and necrosis increased with the concentrations of BBD9, which also dose-dependently increased the levels of cleaved caspase-3, csapase-9, PARP, and LC3II expression. In the tumor-bearing mouse model, BBD9 showed stronger effects than imatinib in reducing the tumor weight, promoting tumor regression, and increasing the body weight.</p><p><b>CONCLUSION</b>BBD9 can effectively inhibit the growth of K562/IR cells in vitro and in vivo by activating cell apoptosis, necrosis and autophage pathways, down-regulating expressions of p210(Bcr-Abl) and IKKa and suppressing the cytoplasm-to- nucleus translocation of NF-κBp65.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the levels and roles of cytokines TNF-α, IL-6 and IL-10 in bronchoalveolar lavage fluid (BALF) in children with Mycoplasma pneumoniae pneumonia (MPP).</p><p><b>METHODS</b>The levels of TNF-α, IL-6 and IL-10 in BALF were measured using ELISA in children with MPP at acute stage (n=45) and at remission stage (n=30). Twenty children without lung lesions severed as the control group.</p><p><b>RESULTS</b>The TNF-α, IL-6 and IL-10 levels in BALF were higher in children with MPP at acute stage than those in the control group (P<0.05). The levels of TNF-α and IL-6 in BALF at remission stage were reduced to the levels similar to the control group and were significantly lower than those at the acute stage in children with MPP. However, the levels of IL-10 in BALF remained at higher levels at remission stage in children with MPP.</p><p><b>CONCLUSIONS</b>The levels of TNF-α, IL-6 and IL-10 in BALF increase in children with MPP at acute stage, suggesting that the cytokines may be involved in the pathogenesis of MPP.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate different characteristics of the video-assisted thoracoscopic (VATS) versus transsternal thymectomy for myasthenia gravis (MG).</p><p><b>METHODS</b>The clinical data of 106 patients who underwent VATS thymectomy for MG between February 2002 and May 2007, and 108 patients who underwent transsternal thymectomy between March 1998 and August 2003 were analyzed retrospectively. In VATS group, there were 64 male and 42 female patients, and the mean age was 38-years-old. In the transsternal group, 68 patients were male and 40 were female, and the mean age was 36-years-old. Analysis of conditions related to the surgical procedure between two groups was made, such as length of surgery, operative bleeding, postoperative drainage, hospital stay, hospitalization expenses and complications. The mean time of follow-up was 38.5 months (ranging from 10 to 67 months). All patients were classified according to the MGFA clinical classification.</p><p><b>RESULTS</b>Intraoperative bleeding in VATS group was (34 +/- 5) ml, significantly less than (150 +/- 23) ml in the transsternal group. Postoperative drainage in VATS group was (42 +/- 18) ml, significantly less than (168 +/- 31) ml in the transsternal group. Complications and hospital stay in VATS group were also significantly lower than those in the transsternal group. There was no significantly different in the long-term outcome between two groups.</p><p><b>CONCLUSION</b>Although both thoracoscopic and transsternal approaches to thymectomy in patients with MG are effective after the long-term follow-up, VATS thymectomy has its specific advantages of minimal invasion, less complications, and rapid recovery.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the outcome of video-assisted thoracoscopic extended thymectomy (VATET) for myasthenia gravis.</p><p><b>METHODS</b>From January 2005 to February 2006, VATET had been performed for 41 patients of myasthenia gravis. Among them, 23 patients were female and 18 were male. The age ranged from 18 to 67 years old, and the disease duration ranged from 1 month to 3 years. In order to achieve maximal benefit, a transverse cervical incision was given access to the peri-thyroid space to remove fat in the neck which may contain ectopic thymus after all thymic tissue, including far-reaching ectopic sites. Peri-thymic adipose tissue in the anterior mediastinum was completely removed.</p><p><b>RESULTS</b>In the 41 patients, mean operative time was 162 min. Sever patients sustained myasthenic crises that required reintubation and mechanical ventilation for a few days. Of all patients, 35 had lymphadenectasis, and 4 had ectopic thymus in the peri-thyroid space. After the 2 years' follow-up, the rate of complete stable remission was 41.4%, and the effective rate was 85.4%.</p><p><b>CONCLUSIONS</b>Video-assisted thoracoscopic thymectomy represents a safe and valid approach for patients with myasthenia gravis. VATET may be a complement to completely remove all thymus including ectopic tissues.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of prostaglandin E(1) (PGE(1)) on the expression of monocyte chemotactic protein-1 (MCP-1) in Kupffer cells (KCs) of rats with hepatic ischemia-reperfusion injury (IRI).</p><p><b>METHODS</b>Seventy-two SD rats were randomized into sham operation group, ischemia-reperfusion group (I/R group) and PGE(1) treatment group (PGE(1) group). Rat models of partial warm ischemia-reperfusion injury of the liver was established, and in PGE(1) group, PGE(1) were given 10 min before the operation. At 1, 6, 12 and 24 h after the reperfusion, blood sample was taken from the inferior vena cava for measuring alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. The KCs were isolated and incubated in vitro, and tumor necrosis factor alpha (TNF-alpha) and interleukin-1beta (IL-1beta) in the supernatant were measured by enzyme-linked immunosorbent assay. MCP-1 expression in the KCs was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR).</p><p><b>RESULTS</b>ALT and AST levels of the PGE(1) group were significantly lower than I/R group (P<0.01). The mRNA and protein expression of MCP-1 and the TNF-alpha and IL-1beta levels in the I/R group significantly increased in the course of reperfusion and slightly decreased at 24 h, but were still significantly higher than those in the sham operation group (P<0.05). The expression of these factors were markedly decreased after PGE(1) treatment as compared with the I/R group (P<0.05).</p><p><b>CONCLUSION</b>PGE(1) can protect against ischemia-reperfusion injury of the rat liver partially by suppressing KCs activation, reducing excessive release of TNF-alpha and IL-1beta from KCs and decreasing the high expression of MCP-1 protein and mRNA.</p>
