The theoretical basis, location, belonging of zang-fu, treatment function and indications, applying principle and manipulation of Umbilical Ring acupoints in Zhuang medicine are explained in this paper. According to Zhuang medicine, umbilicus is an epitome of the body and all the zang-fu and organs in the body have corresponding epitomes like a fetus in front-standing position. The umbilicus is not only a micro-diagnosis system, but also a window for illness treatment that could be divided into superficial, middle and deep layer to respectively communicate different zang-fu and organs. The umbilical inner ring and outer ring are collectively called Umbilical Ring acupoints, they could dredge paths, regulate the balance of qi and blood to regulate qi, expel poison, tonify deficiency and remove stasis to treat many types of diseases in the whole body.

OBJECTIVETo investigate the role of EPHA2 in regulating apoptosis, proliferation and vasculogenic mimicry of osteosarcoma cells, by gene silencing through RNA interference.

METHODSEPHA2-siRNA plasmids were achieved by gene cloning. The plasmids were transfected into human osteosarcoma cells (MG63). The expression level of EPHA2 protein was measured by Western blotting. The proliferation, apoptosis and vasculogenic mimicry features of osteosarcoma MG63cells were assessed by light microscopy, MTIP assay, flow cytometry, annexin V-FITC/PI and HE staining, respectively.

RESULTSThe EPHA2-siRNA plasmid was confirmed by DNA sequencing. After treatment with Sequence-specific siRNA targeted EPHA2, the protein level of the transfected group decreased significantly. As compared to non-siRNA transfected cells, the transfected group showed lower proliferation, higher and earlier apoptosis and less osteosarcoma-generated vasculogenic mimicry.

CONCLUSIONEPHA2 gene may be involoved in apoptosis and proliferation of osteosarcoma cells, and may be necessary for vasculogenic mimicry. Down-regulation of EPHA2 expression by sequence-specific siRNA may be considered as a new option in the treatment of EPHA2 over-expressing cancer including osteosarcoma in future.

OBJECTIVETo study the commodity specification and grade standard of Pseudostellaria Radix, for standardizing market order and achieving industrialization, standardization and modernization of Pseudostellariae Radix.

METHODThe different areas and grade medicinal materials of Pseudostellariae Radix were respectively measured in quantitative characteristics of appearance, and the present grade classification of Pseudostellaria Radix was scientifically verified by the content of polysaccharide. Then the determination data were evaluated by spss correlation analysis, principal component analysis and cluster analysis. So combining with the actual production, the commodity grade standard of Pseudostellariae Radix was formulated.

RESULTCorrelation analysis indicated that the present grade classification of Pseudostellaria Radix was reasonable, and the more the grade of Pseudostellariae Radix was high, the more the content of polysaccharide was high. Meanwhile, length as a classification index was not suitable for the commodity grade standard of Pseudostellariae Radix. Using principal component analysis and cluster analysis, combining actual production, the thickest diameter, weight of single root tuber and the number of 50 g root tuber were filtrated and the grade was divided into 5 ranks: big, mid- dle, small selected goods, big ungraded goods and small ungraded goods.

CONCLUSIONthe commodity specification and grade standard of Pseudostellariae Radix that mainly included the thickest diameter, weight of single root tuber and the number of 50 g root tuber was formulated, the standard was divided into 5 grade. Each grade was not only consistent with the present situation of medicinal materials market, it could also reflected the intrinsic quality of Pseudostellariae Radix. In conclusion, the standard could be used as a classifica- tion basis to the commodity specification and grade.

OBJECTIVE: To evaluate influences of regular-dose of adriamycin (ADR) on heart function and sarcoplasmic reticulum (SR) Ca2+ -ATPase in cardiomyocyte of rabbits. METHODS: Nine rabbits received intraveneous injection of ADR (2mg/kg) once a week for 8 weeks, the rabbits injected with saline were used as control group. Cardiac output (CO), blood pressure (BP), mean artery pressure (MAP), left ventricular systolic pressure( LVSP), left ventricular end-diastolic pressure (LVEDP), calcium in cardiomyocyte (MyoCa2+) of rabbits and SR Ca2+ -ATPase activity were examinated 3 weeks after the final injection. RESULTS: CO, LVSP and SR Ca2+ -ATPase activity were significantly decreased in ADR treated group compared with the control group. Conversely, LVEDP and MyoCa2+ were significantly increased in ADR treated rabbits. CONCLUSION: Heart function can be decreased by regular-dose of ADR in injection. Calcium overload in cardiomyocyte and decrease of SR Ca2+ -ATPase activity is important physiopathologic mechanism in ADR-induced impairment of heart.

OBJECTIVEThe study was designed to investigate the changes in CD(69), CD(25) and HLA-DR expressions in peripheral blood T cell in Kawasaki disease (KD).

METHODSThe authors detected CD(69), CD(25) and HLA-DR expressions in peripheral blood T cell by using flow cytometry. The patients who met the diagnostic criteria for KD comprised sixteen boys and fifteen girls (4 - 60 months of age; mean, 26 +/- 18 months). All received intravenous gammaglobulin at a dose of 1 g/(kg.d), for 2 days and oral aspirin at a dose of 30 - 50 mg/(kg.d). In case of persistent fever, a repeated dose of intravenous gammaglobulin or I.V. methylprednisolone at a dose of 20 mg/(kg.d) for three daily doses was attempted. The authors tested blood samples from 17 healthy controls consisting of nine boys and eight girls (3 - 84 months of age; mean, 25 +/- 18 months) and the samples from 31 patients.

RESULTSThe percentage of peripheral blood CD(3)(+) T lymphocyte was (54.4 +/- 9.0)% in acute stage of KD and (65.0 +/- 7.0)% in healthy controls. There was a significant difference between the two groups (P < 0.001). The values of CD(69)(+) [(11.2 +/- 12.6)%, vs. (0.6 +/- 0.4)%], CD(25)(+) [(9.2 +/- 3.5)% vs. (3.9 +/- 1.8)%] and HLA-DR(+) [(8.3 +/- 5.0)% vs. (4.3 +/- 2.3)%] in KD patients were markedly increased compared to those of the healthy controls. After intravenous gammaglobulin treatment, the percentage of CD(3)(+)CD(69)(+) and CD(3)(+)CD(25)(+) significantly decreased [CD(3)(+)CD(69)(+): (14.0 +/- 13.0)% vs. (1.6 +/- 1.2)%, P < 0.05; CD(3)(+)CD(25)(+): (7.8 +/- 4.1)% vs. (2.0 +/- 0.6)%, P < 0.01]. However, the CD(3)(+) T lymphocytes increased [(50.8 +/- 5.0)% vs. (64.9 +/- 5.5)%, P < 0.01]. There was no significant difference in expression of CD(3)(+) T lymphocyte cell activating markers between coronary artery disease group and normal coronary artery group in KD cases (P > 0.05).

CONCLUSIONCD(3)(+) T cell activation in the early and middle stages is involved in the mechanism responsible for cardiovascular injury.

Objective To observe the effect of recombinant human erythropoietin injection (RHEI) assisted with mild hypothermia on the clinical efficacy and safety of children with hypoxic-ischemic encephalopathy (HIE). Methods From January 2015 to December 2017, 110 children with HIE were treated in Shijiazhuang No.1 Hospital. Fifty-five children with routine treatment were taken as Western medicine routine treatment group. In addition, 55 children treated with mild hypothermia combined with RHEI were taken as mild hypothermia+RHEI group. Both groups were treated for 14 days and followed up for 10 months. The neonatal behavioral neurological assessment (NBNA) score, mental development index (MDI), psychomotor development index (PDI), myelin basic protein (MBP), S100B protein and neuron specific enolization enzyme (NSE), nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), insulin growth factor-1 (IGF-1), growth hormone (GH), and differences in clinical efficacy in two groups were compared, and the occurrence of adverse reactions was observed. Results The NBNA, MDI, PDI, NGF (μg/L), BDNF (ng/L), IGF-1 (pg/L), and GH (pg/L) of two groups after treatment were higher than those before treatment (the Western medicine routine treatment group: 33.72±3.19 vs. 26.81±2.38, 78.95±5.51 vs. 71.39±4.24, 79.62±4.93 vs. 71.84±4.15, 123.74±22.98 vs. 104.29±15.36, 1 518.35±174.92 vs. 1 197.28±148.43, 38.25±4.96 vs. 23.16±2.87, 39.27±5.24 vs. 20.97±3.15; the mild hypothermia+RHEI group: 39.82±3.36 vs. 26.78±2.53, 84.13±6.29 vs. 71.34±4.27, 85.26±5.74 vs. 71.88±4.13, 145.28±27.52 vs. 104.72±15.41, 1 925.71±204.37 vs. 1 192.61±150.26, 57.94±6.62 vs. 23.13±2.91, 56.43±7.14 vs. 20.94±3.17), NSE (μg/L), MBP (μg/L) and S100B (μg/L) were lower than those before treatment (the Western medicine routine treatment group: 17.05±2.26 vs. 24.96±2.83, 9.71±1.85 vs. 23.14±3.37, 0.93±0.12 vs. 1.49±0.24; the mild hypothermia+RHEI group:12.48±1.94 vs. 25.03±2.81, 5.48±1.42 vs. 23.17±3.35, 0.61±0.07 vs. 1.51±0.25). After treatment, the changes of each index in the mild hypothermia+RHEI group were more significant than those in the control group [NABA:39.82±3.36 vs. 33.72±3.19, MDI: 84.13±6.29 vs. 78.95±5.51, PDI: 85.26±5.74 vs. 79.62±4.93, NSE (μg/L):12.48±1.94 vs. 17.05±2.26, MBP (μg/L): 5.48±1.42 vs. 9.71±1.85, S100B (μg/L): 0.61±0.07 vs. 0.93±0.12, NGF (μg/L): 145.28±27.52 vs. 123.74±22.98, BDNF (ng/L): 1 925.71±204.37 vs. 1 518.35±174.92, IGF-1 (pg/L):57.94±6.62 vs. 38.25±4.96, GH (pg/L): 56.43±7.14 vs. 39.27±5.24, all P < 0.05]. The total effective rate of mild hypothermia+RHEI group was significantly higher than that of Western medicine routine treatment group [94.55% (52/55) vs. 81.82% (45/55), P < 0.05]. There were no serious adverse reactions in the two groups. Conclusion RHEI assisted with mild hypothermia therapy can significantly improve the clinical efficacy and NBNA, MDI, PDI scores of HIE children, reduce the degree of brain injury, and improve the neurological function, with good safety.

OBJECTIVETo investigate the effect and safety of the implantation of a new type of testicular prosthesis in the treatment of testis loss.

METHODSWe recruited for this study 18 patients with testis loss treated by testicular prosthesis implantation, including 10 cases of prostate cancer, 3 cases of anorchia, 2 case of orchiatrophy, 2 cases of hermaphroditism and 1 case of cryptorchidism. The prosthesis was a hollow silicone elastomer YH-G1 made in China, selected according to the volume of the scrotum and the size of the contralateral testis.

RESULTSThirteen of the patients received testicular prosthesis implantation with orchiectomy, and the other 5 underwent the procedure 6 months later. The operation time of testicular prosthesis implantation was (22.6 +/- 4.6) min, ranging from 15 to 30 minutes. All the patients were discharged after 12 hours of postoperative observation, with a mean hospital stay of (1.3 +/- 0.4) days. A follow-up after 6 months revealed no complications in 17 cases. Rejection occurred in 1 case at 3 months after the implantation, ending in the removal of the prosthesis. Of the 17 successful cases, 15 were very satisfied with the size of the prosthesis, 14 with its weight, 12 with its comfortableness, and all with the appearance of the scrotum and the position of the prosthesis, while 5 found the implant too rigid.

CONCLUSIONThe implantation of the new home-made silicone elastomer testicular prosthesis YH-G1 was safe and effective for the treatment of testis loss, and could meet the esthetic and psychological requirements of the patient. But further observation is needed for its long-term complications and influence on the patient's quality of life.

Objective To investigate antimicrobial resistance among gram-negative bacilli in China in 2010.Methods A total of 1 259 consecutive and non-repetitive gram-negative bacilli were isolated from 13 teaching hospitals from September to December in 2010 in China.All of these isolates were sent to the central laboratory for re-identification and susceptibility testing.The MIC of meropenem and other antibacterial agents were determined by agar dilution method.Interpretive results was determined by CLSI M100-S21.Results The activity of 14 antibacterial agents against 845 Enterobacteriaceae isolates was as follows in order:meropenem ( 98.1％,829 ),amikacin ( 94.0％,794 ),imipeuem ( 90.0％,761 ),piperacillin/tazobactam ( 87.5％,739 ),cefepime ( 83.0％,701 ),ertapenem ( 82.4％,696 ),cefoperazone/sulbactam ( 80.3％,678 ),colistin (75.4％,637),ceftazidime (70.0％,591 ),ciprofloxacin (59.1％,499 ),cefoxitin ( 54.8％,463 ),ceftriaxone ( 53.5％,452 ),cefotaxime ( 52.3％,442 ) and minocycline(51.5％,435).The prevalence of ESBL was 61.3％ (106/173) in Escherichia coli,which was much higher than 41.2％ (70/170) in Klebsiella pneumoniae.The susceptibility rate of Klebsiella pneumoniae against meropenem,imipenem,amikacin and colistin were more than 90％,but were highly resistant to ceftriaxone and cefotaxime.Over 80％ of Enterobacter cloacae,Enterobacter aerogenes,Citrobacter freundii,were susceptible to meropenem,amikacin,cefepine,cefoperazone/sulbactam,imipenem,piperacillin/ tazobactam,and ertapenem.The most active antibiotics against Pseudomonas aeruginosa were Colistin (98.4％,182),Amikacin ( 85.9％,159 ),Piperacillin/Tazobactam ( 80％,148 ),Ceftazidime ( 79.5％,147),Meropenem (74.1％,137),Ciprofloxacin (74.1％,137),Cefepime (73.5％,136),Imipenem (71.9％,132) and Cefoperazone/Sulbactam (70.8％,131 ).Less than 37％ of Acinetobacter baumannii isolates were resistant to carbapenems.The susceptible rate to Minocycline was 47.8％.Colistin kept good activity against Acinetobacter baumannii (susceptible rate,97.8％,n =176),The prevalence of Pan-drug resistant P.aeruginosa and A.baumannii was 18.9％ (n =35),and 61.8％ (n =108),respectively.Conclusions Carbapenems remained very high activity against Enterobacteriaceae.Increasing resistance to the antimicrobials agents test among A.baumanni and P.aeruginosa,especially carbapenems among A.baumanni brought great concern.

[Objective]To investigate the pathological damage caused by aquaporin-4 antibody extracted from patients with neuromyelitis optica spectrum disorders(NMOSD)and the influence of systemic immune status on the local disease focus.[Methods]The C57BL/6 mice were chose for establishing experimental autoimmune encephalomyelitis (EAE).During the peak at onset,serum-derived immunoglobulin G(IgG)from aquaporin-4(AQP4)IgG positive patients and healthy human complement(hC)were injected in the brain parenchyma(EAE+AQP4-IgG+hC group,n=5).The EAE induced mice injected with normal saline(EAE+NS group,n=5)and mice without EAE injected with AQP4-IgG and hC from healthy volunteers(AQP4-IgG + hC group,n=5)were served as control groups. The dramatic loss of AQP4,astrocyte glial fibrillary acidic protein(GFAP),oligodendrocyte myelin basic protein(MBP)and the infiltration of inflammatory cells(T lymphocytes,neutrophils and macrophages)were compared with each group by using immunoflu-orescence,in order to find abnormal changes.[Results]Intracerebral injection of AQP4-IgG together with hC can cause NMO-like lesions,including astrocyte injury,demyelination and inflammatory cell infiltration.However,EAE mice model with intracerebral injection of AQP4-IgG and hC represented more significant loss of AQP4 and GFAP(P=0.008 and P=0.016,respectively)compared with mice without EAE induced.The area of MBP loss was also increased,while there′s no statistical difference.No statistical difference was also found in the number of vessels infiltrated with CD3+T cell,neu-trophils and the area infiltrated with macrophage. Astrocyte proliferation existed in all groups,but no loss of AQP4, GFAP and MBP was found in EAE mice injected with NS.[Conclusion]Intracerebral injection of AQP4-IgG and hC can cause distinct pathological damage and the pathology can be promoted by immune system activated by EAE.Intracerebral injection of AQP4-IgG and hC can mimic the pathogenesis of NMOSD better in EAE mice model.

Objective To investigate antimicrobial resistance among nosocomial gram-negative bacilli in 2006.Methods About 987 consecutive and non-repetitive gram-negative bacilli were isolated from 10 teaching hospitals from Sep.to Dec.in 2006 in China.All of these isolates were sent to the central laboratory for reidentification and susceptibility testing.The minimal inhibitory concentration(MICs)of meropenem and other antibacterial agents were determined by agar dilution method.Results The activity of antibacterial agents against Enterobacteriaceae was as fol lows in descending order of susceptible rate: meropenem(susceptible rate 99.8%),imipenem(99.5%),piperacillin/tazobactam(91.3%),amikacin (89.3%),cefepime(83.8%),cefoperazone/sulbactam(79.7%),ceftazidime(74.7%),cefotaxime (57.7%),ceftriaxone(56.6%),ciprofloxacin(53.6%).The prevalence of extended-spectrum β-Iactamases(ESBL)was 59.0% in Escherichia coli,33.0%in Klebsiella pneumoniae and 8.0%in Proteus mirabilis.The most active agents against E.coli and K.pneumoniae were meropenem,imipenem(99.2%. 100%),piperacillin/tazobactam(90.8%-97.0%),and amikacin(83.8%-92.4%).Cefepime Was more active against K.pneumoniae than E.coli(85.4% vs.65.2%).Against E.cloacae,E.aerogenes and Citrobacter freundii,the most active agents were as follows in desecnding order:meropenem,imipenem (99.2%-100%),amikacin(85.2%-92.6%),cefepime(81.5%-85.9%),piperacillin/tazobactam (73.4%-87.2%),cefoperazone/sutbactam(65.6%-77.7%),and ciprofloxacin(53.1%-72.3%).The most active agents against Pseudomonas aeruginosa were amikacin(83.5%),followed by meropenem (79.1%),piperacillin/tazobactam(74.1%),and imipenem(70.9%).The most susceptible agents against Acinetobacter baumannii were imipenem(79.1%),meropenem(73.4%) and cefoperazone/ sulbaetam(54.7%).Mutiresistant A.baumannii increased up to 53.0%.The most active agents against Burkholderia cepacia were meropenem(73.3%),eeflazidime(73.3%),and piperacillin/tazobactam (62.2%).Conclusions Carbapenems remained very high activity against Enterobacteriaceae.Increasing resistance to 10 antimicrobials agents tested from A.baumanni and P.aeruginosa brought great concern.
