OBJECTIVETo explore the better therapy in the treatment of ganglion.

METHODSNinety cases of ganglion were randomized into a two-way quintuple puncture group, a common quintuple puncture group and a fire needling group, 30 cases in each one. In the two-way quintuple puncture group, the "9-in-1" multiple penetrating needling technique was used. In the common quintuple puncture group, the traditional "5-in-1" multiple penetrating needling technique was applied. In the fire needling group, the traditional multiple fire needling technique was adopted. The treatment was given once a day, 3 treatments made one session and the efficacy was analyzed statistically after 1 session treatment in the three groups.

RESULTSAll of the three therapeutic methods achieved the efficacy on ganglion. The curative rate was 96. 7% (29/30) in the two-way quintuple puncture group, which was better obviously than 66.7% (20/30) in the common quintuple puncture group and 60. 0% (18/30) in the fire needling group (both P<0. 01).

CONCLUSIONThe two-way quintuple puncture technique achieves the remarkably superior efficacy on ganglion as compared with the common quintuple puncture technique and fire needling technique.

To characterize the genomic sequence and arrangement of WU polyomavirus (WU virus) identified in clinical specimens collected from children with acute respiratory infections in Beijing, China, the sequences of capsid proteins VP1, VP2, and the large tumor antigen (LTAg), as well as the 5'-terminal sequence of WU virus, were amplified from the clinical specimen with ID number of BJF5276 which was determined as WU virus positive by PCR amplification. The PCR amplicons were sequenced, and genomic sequence analysis was performed by using the software DNAStar. In addition, VP2 coding-region sequences were amplified from other 21 clinical specimens identified as WU virus positive to investigate the gene diversity of WU virus. The genomic sequence of WU virus BJF5276 with accession number of HQ218321 in GenBank was 5,229 base pairs in length with 3 major coding domain sequences (CDS) sited on one strand coding for capsid proteins VP2, VP3 and VP1, and two CDS sited on the complementary strand coding for small tumor antigen (STAg) and LTAg; These 22 VP2 CDS sequences including 5 sequences submitted to GenBank were compared with 64 corresponding sequences downloaded from GenBank by MegAlign of DNAStar software, indicated that these sequences coming from children in Beijing shared high homology (over 98.8%) with those from GenBank. Phylogenetic analysis of these VP2 CDS by using Neighbor-joining (NJ) analyses with 2,000 bootstraps (Mega 4.0) showed that 20 sequences out of 22 belonged to clade Ia, and other 2 of them belonged to clade III, including 1 clustered in IIIa and 1 in a novel cluster proposed as IIIc. In conclusion, the genomic sequence of WU polyomavirus detected from clinical specimens from children in Beijing is closely related to other WU polyomaviruses in the feature of genomic coding region arrangement. Overall variation of VP2 CDS was very low, and there were different clades circulating in Beijing with a dominant clade Ia, which is different from dominated Ib circulating in other parts of the world reported previously, and a novel clade IIIc was proposed.

Objective:To observe the effect of electroacupuncture (EA) pretreatment on adenine nucleotides in the myocardial tissues of the myocardial ischemia-reperfusion injury (MIRI) rats, and to explore the mechanism of EA pretreatment on myocardial prevention and protection in MIRI rats. Methods:Forty SPF male Sprague-Dawley (SD) rats were randomly divided into 5 groups: a blank group, a sham operation group, a model group, an EA at Neiguan (PC 6) group and an EA at Hegu (LI 4) group, with 8 rats in each group. Rats in the blank group only received binding to the rat plate, 30 min/time, once a day for 7 d; on the 7th day, rats in the sham operation group were subjected to threading for 40 min at the left anterior descending coronary artery without ligation, and then the rats were allowed to stand for 60 min before collection of the specimens; on the 7th day, rats in the model group were subjected to threading at the left anterior descending coronary artery with ligation, for 40 min before the blood flow was restored, and then the rats were allowed to stand for 60 min before collection of the specimens; on the 7th day of pretreatment with EA at Neiguan (PC 6) or Hegu (LI 4) for 30 min per day (once a day for 7 d), rats in the EA at Neiguan (PC 6) group and EA at Hegu (LI 4) group were subjected to modeling and sample collection same as in the model group. The left ventricular myocardium of the lower left anterior descending coronary artery was collected from rats in all 5 groups. Hematoxylin-eosin (HE) staining and transmission electron microscope (TEM) were used to observe the changes in myocardial pathological morphology. The change in the adenine nucleotide level of myocardial tissue was measured by high performance liquid chromatography (HPLC). Results:The HE staining and ultrastructure showed that the myocardial injury was severer in the model group compared with the sham operation group. Compared with the model group, the myocardial injury in the EA at Neiguan (PC 6) and the EA at Hegu (LI 4) groups was mild or hardly any. The adenine nucleotide levels in the sham operation group and the model group were all decreased compared with the blank group (allP<0.05); compared with the sham operation group, the adenine nucleotide level of the model group was also decreased, but the difference was not statistically significant (P>0.05); compared with the model group, the adenine nucleotide level in the EA at Neiguan (PC 6) group was increased (P<0.05), and the adenine nucleotide level in the EA at Hegu (LI 4) group was significantly increased (P<0.01). The adenine nucleotide level in the EA at Hegu (LI 4) group was higher than that in the EA at Neiguan (PC 6) group, but the difference was not statistically significant (P>0.05). Compared with the EA at Neiguan (PC 6) group, the levels of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) in the EA at Hegu (LI 4) group were significantly increased (allP<0.01). Conclusion:Both EA at Neiguan (PC 6) and Hegu (LI 4) can alleviate the pathological damage to myocardium in MIRI rats, and increase the adenine nucleotide level in myocardial tissues, and thus protect MIRI rats. EA at Hegu (LI 4) has a better protective effect than Neiguan (PC 6).

Background:Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course,and available treatments for delaying the progression to end-stage renal disease are limited.This study aimed to assess the efficacy and safety of the traditional Chinese medicine,Niaoduqing particles,for delaying renal dysfunction in patients with stage 3b-4 CKD.Methods:The present study was a prospective,randomized,double-blind,placebo-controlled,multicenter clinical trial.From May 2013 to December 2013,300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml,min-1· 1.73 m-2,aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces.Patients were randomized in a 1∶1 ratio to either a test group,which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks,or a control group,which was administered a placebo using the same methods.The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment.The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test.The present study reported results based on an intention-to-treat (ITT) analysis.Results:A total of 292 participants underwent the ITT analysis.At 24 weeks,the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the test and control groups,respectively (Z =2.642,P =0.008),and the median change in eGFR was-0.2 (-4.3-2.7) and-2.2 (-5.7-0.8) ml·min-1.1.73 m-2,respectively (Z =-2.408,P =0.016).There were no significant differences in adverse events between the groups.Conclusions:Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD.This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

OBJECTIVETo study the value of immunomarkers CXCL13, CD10, bcl-6 in pathologic diagnosis of angioimmunoblastic T-cell lymphoma (AITL).

METHODSOne hundred and fifteen cases of AITL, 30 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) and 30 cases of reactive lymph nodes with paracortical hyperplasia (RH) encountered during the period from January, 1990 to January, 2008 were retrieved from the archival files of the Department of Pathology, West China Hospital of Sichuan University, China. The morphologic features were reviewed and compared. Immunohistochemical study was performed by SP method for CXCL13, CD10, bcl-6, CD21, CD3epsilon, CD3, CD45RO, CD20 and Ki-67. TCR-gamma gene rearrangement study was also carried out.

RESULTSRegressed follicles were evident in 7.8% (9/115) of AITL cases, 6.7% (2/30) of PTCL, NOS cases and 83.3% (25/30) of RH cases, respectively. A marked increase of number of arborizing venules was shown in 98.3% (113/115) of AITL cases, 63.3% (19/30) of PTCL, NOS cases and 76.7% (23/30) of RH cases, respectively. In lymph nodes with paracortical hyperplasia, the expression of CXCL13, CD10 and bcl-6 were restricted to the germinal centers. In AITL, 96.5% (111/115) of cases showed CXCL13 expression, in contrast to 26.7% (8/30) of PTCL, NOS. Expression of CD10 and bcl-6 were found in the neoplastic cells in 50.4% (58/115) and 78.3% (90/115) of AITL, and 3.3% (1/30) and 3.3% (1/30) of PTCL, NOS, respectively. Irregular meshworks of CD21-positive follicular dendritic cells were found in all the AITL cases. Clonal TCR-gamma rearrangement was detected in 83% (83/100) of the AITL cases.

CONCLUSIONSAITL is a type of lymphoma originated from the follicular helper T cells. Detailed morphologic assessment and use of immunohistochemical markers are essential for accurate diagnosis.

Ovarian cancer is one of the three major cancers in gynecology. Ovarian cancer has insidious symptoms in its early stages and mostly has progressed to advanced stages when detected. Surgical treatment combined with chemotherapy is currently the main treatment, but the 5-year survival rate is still less than 45%. Angiogenesis is a key step in the growth and metastasis of ovarian cancer. The inhibition of ovarian cancer angiogenesis has become a new hotspot in anti-tumor targeted therapy, which has many advantages such as less drug resistance, high specificity, few side effects, and broad anti-tumor spectrum. Modern research has confirmed that traditional Chinese medicine(TCM) can inhibit tumor angiogenesis by inhibiting the expression of pro-angiogenic factors, up-regulating the expression of anti-angiogenic factors, inhibiting the proliferation of vascular endothelial cells, reducing the density of tumor microvessels, and regulating related signaling pathways, with unique advantages in the treatment of ovarian cancer. This paper presented a review of the role of TCM in inhibiting ovarian cancer angiogenesis in order to provide references for the optimization of clinical ovarian cancer treatment strategies.

Objective: To detect the expression levels of M1-type polarization and autophagy-related indicators in the liver of trichloroethylene (TCE) -sensitized mice, and to explore the role of liver tumor necrosis factor-α (TNF-α) and tumor necrosis factor receptor 1 (TNFR1) in regulating M1-type Kupffer cells autophagy in liver injury in TCE-sensitized mice. Methods: In November 2019, according to simple random grouping, 45 SPF grade BALB/c female mice (6-8 weeks old) were divided into 4 groups: blank control group (n=5) , solvent control group (n=5) , TCE treatment group (n=18) , TCE+R7050 (inhibitor) treatment group (n=17) . Transdermally sensitized mice, 24 h after the last challenge, the mice were divided into TCE sensitized group and TCE non-sensitized group according to the skin reaction score. The livers of mice were harvested, and the pathological changes of the livers were observed under light and electron microscopes. Western blotting was used to detect the expressions of TNF-α, TNFR1 and autophagy-related indexes. The expression of inducible nitric oxide synthase (iNOS) , a marker of M1-type Kupffer cells, was detected by immunohistochemistry, and the occurrence of autophagy in M1-type Kupffer cells was detected by immunofluorescence double-labeling method. Results: The sensitization rate of TCE treatment group was 38.9% (7/18) , and TCE+R7050 treatment group was 35.3% (6/17) , with no significant difference between the two groups (P=1.000) . Compared with the blank control group, mice in the TCE sensitized group had abnormal liver ocytes, obvious liver injury, reduced mitochondria and broken endoplasmic reticulum. Western blotting results showed that the expressions of TNF-α and TNFR1 protein in the liver of the mice in the TCE sensitized group increased, the expression of iNOS protein in M1-type Kupffer cells increased, and the expressions of autophagic microtubule-associated protein 1 light-chain 3 (LC3B) and Beclin1 protein were decreased (P<0.05) . The results of immunohistochemistry showed that iNOS was not significantly expressed in the blank control group and solvent control group, and a small amount of expression was found in the TCE non-sensitized group, the positive staining area was obvious in TCE sensitized group, and the expression of iNOS was significantly increased (P<0.05) . Immunofluorescence results showed that the iNOS protein levels in the blank control group, solvent control group and TCE non-sensitized group were lower, and only partially colocalized with P62; the colocalization of iNOS with P62 in the TCE sensitized group was significantly increased. Conclusion: TNF-α/TNFR1 signaling pathway may promote liver injury in TCE-sensitized mice by inhibiting autophagy of M1-type Kupffer cells.

OBJECTIVES: To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention. METHODS: A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups. RESULTS: After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001). CONCLUSIONS The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

BACKGROUNDA multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage.

METHODSAdult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices.

RESULTSChanges of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that.

CONCLUSIONSThe domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.
