OBJECTIVE:
To investigate the clinical and genetic characteristics of a family with hereditary spherocytosis (HS), to clarify the cause of the disease, and to provide the basis for genetic counseling and prenatal diagnosis.
METHODS:
The clinical data of proband and his parents were collected, and HS-related pathogenic genovariation of the proband was detected by high throughput sequencing. Suspected pathogenic mutation sites were verified by PCR-Sanger sequencing, and the fetus were conceived by a proband mother underwent prenatal diagnosis.
RESULTS:
Clinical manifestations of the proband showed moderate anemia, mild splenomegaly, and jaundice (an indirect increase of bilirubin). The gene detection showed that the proband showed compound heterozygous mutations of SPTB gene c. 6095T > C (p.Leu2032Pro) and c. 6224A > G (p.Glu2075Gly), which was inherited from the asymptomatic mother and father, respectively. Both mutations were detected rarely in the common population. Prenatal diagnosis revealed that the fetus inherited a mutant gene of the mother.
CONCLUSION
The compound heterozygous mutations of SPTB genes c.6095T>C (p.Leu2032Pro) and c.6224A>G (p.Glu2075Gly) were the causes of the family disease, which provides a basis for family genetic counseling and prenatal diagnosis. This report is the first one found in the HGMD,1000G and EXAC database, which provides an addition to the mutation profile of the SPTB gene.

PURPOSE:
Early application of protease inhibitors through the intestinal lumen could increase survival following experimental shock by blocking the pancreatic digestive enzymes. Hence, it was hypothesized that two-route injection (intraintestinal + intravenous) of ulinastatin (UTI), a broad-spectrum protease inhibitor, could better alleviate intestinal injury than single-route injection (either intravenous or intraintestinal).
METHODS:
A sepsis model induced by lipopolysaccharide on rats was established. The rats were randomly divided into five groups: sham, sepsis, UTI intravenous injection (Uiv), UTI intraintestinal injection (Uii), and UTI intraintestinal + intravenous injection (Uii + Uiv) groups. The mucosal barrier function, enzyme-blocking effect, levels of systemic inflammatory cytokines, and 5-day survival rate were compared among groups. The small intestinal villus height (VH), crypt depth (CD), and two components of mucosal barrier (E-cadherin and mucin-2) were measured to evaluate the mucosal barrier function. The levels of trypsin and neutrophil elastase (NE) in the intestine, serum, and vital organs were measured to determine the enzyme-blocking effect.
RESULTS:
Compared with the single-route injection group (Uiv or Uii), the two-route injection (Uii + Uiv) group displayed: (1) significantly higher levels of VH, VH/CD, E-cadherin, and mucin-2; (2) decreased trypsin and NE levels in intestine, plasma, and vital organs; (3) reduced systemic inflammatory cytokine levels; and (4) improved survival of septic rats.
CONCLUSION
Two-route UTI injection was superior to single-route injection in terms of alleviating intestinal injury, which might be explained by extensive blockade of proteases through different ways.

Targets group identification in complex Chinese medicine system is a key step for revealing the potential mechanism of Chinese medicine. The solid beads with magnetic core and benzophenone-modified surface were made in our study, and then benzophenone was activated and cross-linked with the C-H bonds of chemical compositions in Chinese medicines under UV excitation. Thus the chemical compositions of modified Wuzi Yanzong pill(MWP) were linked to the solid bead surface, and enriched the neuroprotective targets group of MWP after being co-incubated with nerve cell lysate. We performed proteomics analysis on these targets and discovereda total of 32 potential binding targets. KEGG analysis revealed that these targets were mainly associated with Hippo and Cell cycle signaling pathways, suggesting that MWP might be involved in regulating the proliferation and differentiation of neural stem cells. Our findings elucidate the potential targets and mechanism of MWP on anti-dementia and neuroprotection, and further providean approach for investigating the targets group in complex Chinese medicine system. This novel method may provide methodological references for exploring the pharmacological mechanism of Chinese medicinal formulae in the future.

Objective To investigate the effects of separate and direct bee sting punctures at acupoints on ESR and RF in rheumatoid arthritis. Method Seventy-two patients with rheumatoid arthritis were randomized to observation and control groups, 36 cases each. The observation group received separate bee sting puncture at acupoints and the control group, direct bee sting puncture at acupoints. In both groups, treatment was given once every other day, three times a week, one week as a course, for two courses. ESR and RF were measured in the two groups before treatment and at one and two weeks after. Result ESR and RF changed significantly in both groups after treatment compared with before (P<0.05). The effects of the two treatments on rheumatoid arthritis-related ESR and RF were equal and there was no statistically significant difference between the two groups (P>0.05). Conclusion Both separate and direct bee sting punctures at acupoints can reduce ESR and RF in rheumatoid arthritis. Separate bee sting puncture at acupoints is easy for the patients to accept.

OBJECTIVETo investigate the correlation between regulatory T (Treg) cells and postmenopausal osteoporosis and the antiosteoporotic effect of 1,25-dihydroxyvitamin D3 [1,25(OH)₂D₃] in relation to Treg cells.
METHODSFifty female BALB/c mice were randomly divided into five groups: the basal control (BAS), Sham, ovariectomy (OVX), OVX+diethylstilbestrol (OVX+DES), and OVX+1,25(OH)₂D₃. Tibias were harvested and processed with decalcification for quantitative bone histomorphometry. Femurs were stained by immunohistochemistry to detect Foxp3 protein expression. Spleens were used to detect Treg and Foxp3 gene expression by flow cytometry and quantitative RT-PCR, respectively.
RESULTSIn comparison with the Sham group, a significant decrease was found in the OVX group in such indices as trabecular bone volume/total tissue area (BV/TV), trabecular number (Tb.N) and trabecular thickness (Tb.Th). 1,25(OH)₂D₃and DES partly prevented the decrease in BV/TV, Tb.N, Tb.Th in OVX mice. Treg cell number, Foxp3 mRNA expression in spleen and Foxp3 protein expression in femur significantly decreased in the OVX-treated group compared with those in the sham group. 1,25(OH)2D₃and DES significantly increased Treg cell number and Foxp3 expression. Treg cells and Foxp3 gene expression were related to bone histomorphometric parameters.
CONCLUSIONThe decrease in Treg cell numbers is relevant to the postmenopausal osteoporosis. The antiosteoporosis of 1,25(OH)₂D₃is related to regulatory T cells.

To analyze the genetic characterization of epidemic rubella virus strains isolated in Liaoning from 2007-2012, a total of 145 rubella virus strains were isolated using Vero/Slam cell line from the patients' throat swabs during rubella outbreaks and sporadics cases in Liaoning Province from 2007 to 2012. Fragments of 945 nucleotides containing 1E gene from 145 rubella virus isolates were amplified by RT-PCR, the PCR products were sequenced and analyzed. Based on the 739 nucleotides of 1E gene, the phylogenetic trees were constructed with 32 WHO rubella reference strains of 13 genotypes downloaded from GenBank and 145 rubella virus strains. The results showed that the 145 rubella virus strains in 2007 -2012 belonged to genotype 1E, nucleotide acids and amino acids similarities were 97.2%-100.0% and 97.6%-100.0%, respectively. Compared to the 1E reference strains(Rvi/ Dezhou.CHN/02, RVi/MYS/01), the nucleotide acids and amino acids similarities were 96.6%-99.2% and 98.2%-100.0%, respectively except for one amino acid change (Val246-Ala246) of RVi/Shenyang. Liaoning. CHN/13.11/13, and Asp262-Asn262 of RVi/Shenyang. Liaoning. CHN/13.11/4 and RVi/Liaoyang. Liaoning. CHN/26. 11/2. there had no change found in the important antigenic epitope sites, the hemagglutination inhibition and neutralization epitopes of the other rubella viruses. All the 145 strains isolated had the same amino acid change (Leu338--Phe338) in E1 protein. These findings suggested that genotype 1E of rubella virus was the predominant genotype in Liaoning province. the rubella prevailed in recent six years was mainly caused by rubella viruses genotype 1E with multi-transmission routes.
