Objective To investigate the expressions of transforming growth factor beta receptors (TGF beta R), receptor-activated Smads and common-partner Smad in condylomata acuminata. Methods Tissue samples were collected from 20 patients with condylomata acuminata and 15 normal human controls.EliVisionTM plus immunohistochemical technique was used to detect the distribution and expression of TGF beta R Ⅰ , TGF beta R Ⅱ, Smad1/2/3, phosphorylated Smad2/3 and Smad4 in condylomata acuminata and normal control skin. Results Positive immunohistochemical staining for TGFbeta R Ⅰ , TGFbeta R Ⅱ,Smad1/2/3, p-Smad2/3 and Smad4 was detected in the epidermis of normal control skin. The intensity of im-munohistochemical staining was significantly lower for TGFbeta R Ⅰ , TGFbeta R Ⅱ, Smad1/2/3, p-Smad2/3and Smad4 in the epidermis of condylomata acuminata than in that of normal control skin (P < 0.05 or < 0.01). Conclusion The expressions of TGF beta R, receptor-activated Smads and common-partner Smad are decreased or absent in the epidermis of condylomata acuminata, which might interfere with TGF be-ta/Smad signaling and contribute to the development of epidermal hyperplasia in condylomata acuminata.

OBJECTIVETo explore the clinical effect of low dose pituitrin in children with septic shock.

METHODSA total of 48 pediatric cases with septic shock, in whom 6 hours, conventional treatment could not reverse shock from January 2008 to December 2010, were selected for this study. The patients were divided into two groups randomly (completely random design) (control group 24, remedial group 24). The conventional treatment included antibiotics/fluid resuscitation/correcting acid-base imbalance, glucocorticoid, organ (heart/lung) support, dopamine 1 - 15 µg/(kg·min) and norepinephrine 0.5 - 2 µg/(kg·min) pumped in continuously in the control group. In initial 6 hours the same treatment was given to the remedial group, while low dose pituitrin (0.01 - 0.03 U/min) was pumped additionally during the rest of time. The therapeutic effect on correcting shock was evaluated in both groups.

RESULTSThe total effective rate was 76.2% in the remedial group and 40.0% in the control group; the mortality was 33.3% and 60% respectively. The difference between both groups was significant (P = 0.025).

CONCLUSIONLow dose pituitrin could improve the clinical effect significantly in children with septic shock in whom 6 hours conventional treatment failed to correct shock, shorten the total periods of treatment, and decrease mortality.

OBJECTIVETo establish the specific 16S-23S rRNA gene spacer regions pattern in different bacteria using polymerase chain reaction (PCR), restriction fragment length polymorphism (RFLP), DNA cloning and sequences analysis.

METHODSA pair of primers were selected from highly conserved sequences adjacent to the 16S-23S rRNA spacer region. Bacterial DNA of sixty-one strains of standard bacteria and corresponding clinical isolates representative of 20 genera and 27 species was amplified by PCR, and further studied by RFLP, DNA cloning and sequences analysis. Meanwhile, all specimens were examined by bacterial culturing and PCR-RFLP analysis.

RESULTSThe 27 different standard strains showed one, two, three or more than three bands. The sensitivity of PCR reached 2.5 colony-forming unit (CFU), and there was no cross reaction to the human, fungal or viral genomic DNAs. Fifteen species could be distinguished immediately by PCR, while another 10 species were further identified by Hinf I or Alu I digestion. Klebsiella pneumoniae (Kp) and Enterococcus durans (Ed) could not be differentiated from each other by Alu I or Hinf I digestion. The spacer sequences of the Kp and Ed were 908 bp and 909 bp, respectively, and they differed only at the site of the 779th nucleotide. The former was G, and the latter was A. The 760 - 790 bp sequence of Kp was as follows: CGACTGCACCGCCTCCTAC / GGCCGCGTATTC. The 760 - 790 bp sequence of Ed was as follows: CGACTGCAC CGCCTCCTAC / AGCCGCGTATTC. Only one enzyme XmaIII, could discriminate the two. The cleaving site of XmaIII is C downward arrow GGCCG. Kp DNA was cleaved into 778 bp and 130 bp fragments, while E. durans was not. Of 42 specimens with suspected septicemia, 15 were positive (35.7%) on blood culture, and 27 on PCR (64.29%). The positive rate of PCR was significantly higher than that of blood culture (P < 0.01). Of the six CSF specimens, one was positive for Staphylococcus epidermidis (Se) on culture as well as by PCR, while two specimens which were negative on cultures were positive by PCR and were diagnosed as Se according to its DNA pattern. One specimen was culture-positive for Cryptococcus neoformans (Cn) but was negative by PCR. The other two specimens were negative by both PCR and culture. Fifteen blood samples from healthy children were negative by both blood culture and PCR.

CONCLUSIONSThe method of detecting bacterial 16S-23S rRNA spacer regions using PCR-RFLP techniques was specific, sensitive, rapid and accurate in detecting pathogens in clinical bacterial infections.

AIMTo investigate the effects of cyclosporin A (CsA) on growth and collagen synthesis of cardiac fibroblasts (CFs) induced by arginine vasopressin (AVP).

METHODSCFs of neonatal Sprague-Dawley rats were isolated by trypsinization and cultured; growth-arrested CFs were stimulated with 1 x 10(-7) mol x L(-1) AVP in the presence or absence of CsA (0.05, 0.5 and 5 micromol x L(-1)). MTT and flow cytometry techniques were adopted to measure cell number and analyze cell cycle respectively. Collagen synthesis was determined by measurement of hydroxyproline content in culture supernatant with colorimetry. Calcineurin activity was estimated by chemiluminescence. Trypan blue staining to test the viability of CFs.

RESULTS0.05, 0.5 and 5 micromol x L(-1) CsA inhibited the increase of CFs number induced by 1 x 10(-7) mol x L(-1) AVP in a dose-dependent manner, with the inhibitory rates by 12%, 24% and 29%, respectively (P < 0.05). Furthermore, cell cycle analysis showed 0.5 micromol x L(-1) CsA decreased the S stage percentage and proliferation index of CFs stimulated by AVP (P < 0.05). In culture medium, the hydroxyproline content induced by AVP decreased by 0.5 and 5 micromol x L(-1) CsA (P < 0.05), with the inhibitory rates of 29% and 33%, respectively. CsA completely inhibited the increment of calcineurin activity induced by AVP (P < 0.01), but CsA itself had no effect on the baseline of calcineurin activity and CFs viability.

CONCLUSIONCsA inhibits proliferation and collagen synthesis of CFs by virtue of blocking calcineurin signaling pathway and might provide a novel target for prevention and treatment to cardiac fibrosis.

OBJECTIVETo evaluate the therapeutic effect of Compound Xuanju Capsule (CXC) on autoimmune prostatitis in rat models.

METHODSSixty healthy male Wistar rats were randomly divided into five groups of equal number: blank control, low-concentration purified prostate protein (low-conc PPP), low-conc PPP + CXC treatment, high-concentration PPP (hi-con PPP), and hi-conc PPP + CXC treatment. Autoimmune prostatitis models were established by intragastric administration of PPP solution at 15 mg/ml (low concentration) and 80 mg/ml, respectively. At 30 days after modeling, the rats in the blank control and low-conc and hi-conc PPP model groups were treated with normal saline, and those in the other two groups with CXC at a daily dose of 0.068 g/ml. At 30, 45, and 60 days, all the animals were sacrificed for observation of pathological changes in the prostate tissue and determination of the levels of IL-8, IL-10, and TNF-alpha in the serum.

RESULTSCompared with the PPP models, the hi-conc PPP + CXC group showed significantly reduced levels of IL-8 and TNF-alpha in the serum at 45 days ([148.54 +/- 17.23] and [62.14 +/- 5.59] pg/ml vs [100.77 +/- 11.08] and [32.63 +/- 2.91] pg/ml, P < 0.05) and at 60 days ([143.69 +/- 17.28] and [59.38 +/- 5.50] pg/mlvs [95.77 +/-10.53] and [29.63 +/- 2.66] pg/ml, P < 0.05), and so did the low-cone PPP + CXC group at 45 days ([128.47 +/- 12.21] and [40.43 +/- 3.64] pg/ml vs [111.76 +/- 10.07] and [35.44 +/- 3.17] pg/ml, P < 0.05) and at 60 days ([131.07 +/- 10.93] and [43.34 +/- 3.91] pg/ml vs [97.46 +/- 8.75] and [30.44 +/- 2.75] pg/ml, P < 0.05). The serum level of IL-10 was remarkably elevated in the hi-cone PPP + CXC group as compared with that of the PPP models at 45 and 60 days ([189.14 +/- 16.78] and [184.14 +/- 15.89] pg/ml vs [230.48 +/- 29.96] and [248.48 +/- 31.03] pg/ml, P < 0.05), and so was it in low-cone PPP + CXC group ([223.14 +/- 17.87] and [224.14 +/- 17.93] pg/ml vs [231.42 +/- 23.18] and [249.42 +/- 24.97] pg/ml, P < 0.05). Pathological examination revealed morphological damages to the prostate tissue and infiltration of inflammatory cells in the model rats, but no obvious changes in the normal controls. At 15 days of treatment, the rats in the PPP + CXC group showed enlarged prostate glandular cavity, mild proliferation of epithelial cells, no obvious infiltration of inflammatory cells in the interstitial tissue, and a few visible fibrous tissues under the light microscope.

CONCLUSIONCompound Xuanju Capsule is efficacious on autoimmune prostatis in rats by reducing inflammatory changes in the prostate tissue and improving the expression of inflammatory factors.
