ABSTRACT
OBJECTIVE@#To explore clinical effect of arthroscopic debridement combined with platelet-rich plasma (PRP) injection for Kellgren-Lawrence(K-L) gradeⅠ-Ⅲ knee osteoarthritis (KOA) .@*METHODS@#Totally 117 patients with KOA who underwent arthroscopic debridement combined with injection from November 2015 to January 2019 were retrospectively analyzed. According to different injection drugs, the patients were divided into sodium hyaluronate group(group A) and PRP group(group B). In group A, there were 60 patients, including 27 males and 33 females, aged from 49 to 67 years old with an average age of (54.1±4.8) years old;12 patients with gradeⅠ, 23 patients with gradeⅡand 25 patients with grade Ⅲ according to K-L clssification, 2 ml(20 g) sodium hyaluronate was injected into knee joint after intraoperative, 1, 2, 3 weeks after operation for 4 times. In group B, there were 57 patients, including 25 males and 32 females, aged from 47 to 70 years old with an average of (55.8±5.0) years old, 10 patients with gradeⅠ, 20 patients with gradeⅡand 27 patients with grade Ⅲ according to K-L classification, injected 5 ml PRP at the same time. Postoperative complications was recorded between two groups. Postoperative visual analogue scale(VAS) and Lysholm score at 3, 6, 12 months were used to evaluate improvement of knee pain and joint function.@*RESULTS@#All patients were followed up for 12 to 19 months with an average of (14.1±1.6) months. There was no significant difference in postopertaive complications between group A and group B (P>0.05). Postoperative VAS score in group A at 3, 6, 12 months were 3.0±0.8, 2.0±0.8, 2.6±0.9 respectively, and 2.9±0.8, 1.9±0.7, 2.2±0.8 in group B respectively; and no differnece at 3 and 6 months after operation between two groups (P<0.05), while VAS score in group B was higher than group A at 12 months after operation(P<0.05). Postoperative Lysholm score in group A at 1, 6, 12 months (86.6±1.8, 93.1±2.0, 86.7±1.7) were lower than group B(88.9±1.9, 95.0±2.0, 89.0±1.9)(P<0.05).@*CONCLUSION@#Arthroscopic debridement combined with sodium hyaluronate or PRP injection for K-L gradeⅠ-Ⅲ KOA could effectively relieve pain and improve joint function with higher safety in short term, but the medium-long-term effect of PRP injection is stable.

OBJECTIVE@#To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP).@*METHODS@#This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed.@*RESULTS@#A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported.@*CONCLUSION@#AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

OBJECTIVE@#To assess the efficacy and safety of Chinese medicine injection (CMI) for treating acute lung injury/acute respiratory distress syndrome (ALI/ARDS).@*METHODS@#Randomized controlled trials (RCTs) were identified by searching 3 English databases and 4 Chinese databases from their inceptions until February 2019. The Cochrane Handbook was used to evaluate risk of bias in the included studies. Data analysis was conducted using RevMan 5.3.3 software.@*RESULTS@#A total of 19 eligible RCTs involving 1,334 participants was included in this systematic review and meta-analysis. The main meta-analysis showed that CMI combined with conventional therapy (CT) was more effective than CT alone in reducing the acute physiology and chronic health evaluation (APACHE) H score [mean difference (MD): -1.74 points, 95% confidence interval (CI): -2.77 to -0.71, I@*CONCLUSIONS@#CMI as an adjuvant therapy showed great potential benefits for the treatment of ALI/ARDS. However, we could not make a definite conclusion due to low quality of included studies and uncertain security. Future studies should focus on improving research design, especially in blindness and placebo. The reporting of adverse events was also needed.
ABSTRACT
Objective To study the changes in coagulation factors stored for different lengths of time after fresh frozen plasma(FFP)thawing.Methods Thirty-two samples of thawed FFP were detected by an automated coagulation analyzer SYSMEX CA-1500 to observe the changes in coagulation function and coagulation factors stored for different lengths of time at 4℃.Results Activated partial thromboplastin time (APTT) was significantly prolonged 12 hours after thawing.However, no significant changes were observed in prothrombin time (PT), thrombin time (TT) or fibrinogen (FIB).Coagulation factors showed varying degrees of attenuation in 24 hours.FⅤ, FⅦ and FⅧ were attenuated significantly in 6 hours by 17.2%, 9.47% and 12.5%, respectively.FⅨ began to attenuate in 12 hours and reached, the lowest rate of 21.1%, while FⅧ had the highest attenuation rate (52.0%) and showed the lowest stability.Conclusion The activity of coagulation factors is decreased with time after FFP thawing ,so it should be transfused as soon as possible to ensure the curative effect and clinical application.
ABSTRACT
Objective To investigate which cells persistantly express interleukin (IL)-1β during the transition of acute neuroinflammaiton to chronic neuroinflammaiton and therefore to provide the evidences of targeted therapy for blocking neuroinflammation.Methods A single does of lipopolysaccharide (LPS) (2 mg/kg,LPS group) or 0.9％ saline (Control group) was intraperitoneally injected in aged rats.Level and gene expression of IL-1β in hippocampual tissue were measured by enzyme-linked immunosorbent assay (ELISA) and real time polymerase chain reaction (RT-PCR),respectively.Cells secreted IL-1β in hippocampus was detected via double fluorescence.Results Glial fibrillary acidic protein (GFAP) and ionized calcium-binding adaptor molecule-1 (IBA-1) positive cells were significantly increased day 1 (P ＜ 0.05) and latee on,gradually return to base level 30 days after LPS exposure.These changes were consistent with mRNA expressions of IL-1β and astrocytes-derived IL-1β in hippocampus.Neither IL-1β expressed in microglia nor in neurons was observed at any time point following LPS-treated.Conclusions LPS induces prolonged activation of glial cells and sustained expression of astrocytes-derived IL-1β,which may play an important role in the transition of acute neuroinflammation to chronic neuroinflammation.

ABSTRACT
Purpose To investigate the expression and significance of RBBP4 and BCL-2 in gastric carcinoma and to explore the relationship between their expression and clinicopathologic characteristics.Methods Immunohistochemistry was used to detect RBBP4 and BCL-2 proteins' expression in the 72 tumor tissues and para-cancer tissues.The association of RBBP4 expression with the clinicopathologic features and the expression correlation between RBBP4 and BCL-2 were analyzed.Real-time PCR was used to detect the expression of RBBP4 mRNA in the 20 tumor tissues and corresponding para-cancer tissues.Results Immunohistochemical results showed that 40 cases of cancer tissues exhibited RBBP4 positive expression,with a positive rate of 55.6％,and 36 cases showed BCL-2 positive expression (50％ positive rate),which were significantly higher than that in para-cancer mucosa (13.9％,16.7％).The over-expression of RBBP4 and BCL-2 was correlated with tumor differentiation,invasive depth and lymphatic metastasis in gastric carcinoma (P＜ 0.05).The expression of RBBP4 was positively correlated with BCL-2 (r =0.559,P ＜ 0.05).Real-time PCR results showed that the relative expression levels of RBBP4 mRNA in gastric carcinoma tissues and para-cancer tissues were 9.988 ± 1.948 and 1.458 ± 0.489 respectively,and the expression in gastric carcinoma was significantly up-regulated as compared with para-cancer tissues.Conclusions The expression of RBBP4 is up-regulated in gastric carcinoma,which may be involved in the development,invasion and metastasis of gastric carcinoma.RBBP4 might become a new diagnostic and prognostic marker for gastric carcinoma.
ABSTRACT
To investigate the effect of patchouli alcohol on inhibiting Helicobater pylori urease activity, and its effect on expression levels of related genes, and lay the foundation for further research on the effect of patchouli alcohol on H. pylori colonization and infection. H. pyloriwas cultured and identified by gram staining, rapid urease test (RUT) and PCR method. Then agar dilution method was used to detect the bacterial survival after 1 h intervention by different concentrations of patchouli alcoholin the acidic (pH 5.3) and neutral (pH 7.0) conditions; berthelot method was used to detect urease activity and RT-qPCR method was used to detect the expression changes of ureA, ureB, ureE, ureH, ureI, and nixA related urease genes. The results showed that the survival rate of H. pyloriwas not significantly changed but the urease activity was obviously decreased after intervention by different concentrations of patchouli alcohol; meanwhile, the expression levels of ureA, ureB, ureE, ureH, ureI, and nixA were decreased to different degrees. Therefore, patchouli alcohol could inhibit H. pylori urease activity in both acidic and neutral conditions, and the mechanism may be related to down-regulation of urease gene expression.
ABSTRACT
ObjectiveTo establish the methodology for identification of clinical isolates of Mycobacterium and to identify the distribution of Mycobacterium species in hospitalized patients with tuberculosis in Heilongjiang province.It would provide the basis for accurate diagnosis of infections with Mycobacterium tuberculosis (MTB) and non-tuberculous Mycobacterium (NTM) as well as for effective therapy.Methods Three hundred and thirty Mycobacterium isolates from 330 tuberculosis patients hospitalized and clinically diagnosed in Harbin Chest Hospital from May 2007 to December 2008 were collected.Genomic DNA from the isolates was extracted after inactivation of Mycobacterium.Molecular identification was carried out using PCR,PCR-restriction fragment length polymorphism (RFLP) and sequencing.ResultsAmong 330 clinical isolates,328 were identified as MTB complex (MTBC),accounting for 99.4％ (328/330); 2 were NTM,accounting for 0.6％ (2/330).Among 328 MTBC isolates,326were MTB,one was Mycobacterium Africanum(M.African) and one was Mycobacterium microti(M,microti),accounting for 99.4％ (326/328),0.3％ (1/328) and 0.3％ (1/328),respectively.It was found that the homology between the two NTM isolates and Mycobacterium avium intracellulare (MAC)was 99％ and 93％,respectively,suggesting that the two NTM isolates were MAC.The homology between the two NTM isolates was 93％.ConclusionsPCR plus PCR-RFLP and sequencing provides an ideal method for precise identification of Mycobacterium species.In the clinically diagnosed tuberculosis patients,the predominant Mycobacterium species is MTB,however M.African,M.microti as well as NTM are also found.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of schistosomiasis control by forbidding livestock denaturing on marshland with Oncomelania snails and to analyse its influencing factors.</p><p><b>METHODS</b>The village of Aiguo, Xinhe, Huangjia, Fanrong, Fengfu and Caomen and its respective nearby marshland, i.e., Aiguoniu, Liulingwei, Huangjianiu, Da, Goulian, and Litouzui, in Jinxian county, Jiangxi province were selected as the pilot areas for implementing the measures of forbidding livestock denaturing on the marshlands with Oncomelania snails during the period of the year 2005 to 2007. A total of 300 residents in each village were randomly chosen for stool examination with the Kato-Katz technique every year. The snail survey was carried out in spring and autumn every year on the marshlands close to the villages with systemic sampling method. The marshlands with a height 16.5 m above the sea level in Futian was selected for snail survey and planting with sesame. The residents aged 20 - 50 years old in Fengfu and Aiguo villages were studied by using questionnaire on the compliance of forbidding livestock pasturing on marshlands with Oncomelania snails.</p><p><b>RESULTS</b>Before implementation of the measures, human infection rate with Schistosoma japonicum was 11.35% (90/793) in Aiguo, 4.00% (12/300) in Xinhe, 4.00% (6/150) in Huangjia, 8.00% (12/150) in Fanrong, 3.17% (4/126) in Fengfu and 6.64% (14/211) in Caomen. After implementation in 2008, human schistsome infection rate in the aforementioned 6 villages was declined to 0.18% (1/551), 0.00% (0/348), 0.00% (0/316), 2.27% (7/308), 1.17% (5/428) and 1.16% (5/430), respectively. Only in Fengfu village the decline of the human prevalence was not significant (χ(2) = 2.4, P = 0.12), while in the other 5 villages, human prevalence rate had been declined significantly (χ(2) = 126.77, P < 0.01; χ(2) = 16.31, P < 0.01; χ(2) = 18.79, P < 0.01; χ(2) = 10.39, P < 0.01; χ(2) = 14.17, P < 0.01, respectively). Infected snails were not found in 5 out of the 6 marshlands close to the villages. Three infected snails were founded in Da marshland because of poor environmental isolation. Before planting, the living snail density was 0.063/0.11 m(2) (34/540), and after planting, the living snail density was 0.0074/0.11 m(2) (4/538), a 88.25% reduction (Z = 12.47, P < 0.01) was recorded through economy crop planting at Futiandaan marshland in 2008. A total of 986 pieces of questionnaire were provided, and 968 valid ones were collected. The results of questionnaire indicate that compliance of forbidding livestock denaturing on marshland with Oncomelania snails in Aiguo and Fengfu villages was 84.38% (216/256) and 75.42% (537/712), respectively. Using logistic regression model, knowledge level on harmfulness of livestock denaturing on marshland with Oncomelania snails, willingness of culture with machine to substitute traditional cattle culture, and willingness of investment to marshland culture development are 3 varieties that affect residents' implementation of forbidding livestock denaturing on marshland with Oncomelania snails.</p><p><b>CONCLUSION</b>The infected snail density and human schistosome infection rate were reduced on the marshlands of well environmental isolation after 2 - 3 years implementation of forbidding livestock denaturing on marshlands with Oncomelania snails. The key influencing factors of forbidding livestock denaturing on marshland with Oncomelania snails are knowledge level on harmfulness of livestock denaturing on the snail infested marshlands, the willingness of machine culture to substitute cattle culture, and the willingness of investment to marshland culture development.</p>
