OBJECTIVETo evaluate the therapeutic effect of Liujunzi decoction combined with Zuojin pills in treating the radioactive duodenitis and their mechanism, and compare with clinical routine acid suppressants combined with mucous membrane protective preparations to study the mechanism of their efficacy.

METHODAccording to the study of Williams J P and characteristics of duodenitis, and by reference to the radiation enteritis modeling standard, we took the lead in establishing the mouse radioactive duodenal injury model. The model mice were randomly divided into the control group (n = 26), traditional Chinese medicine (TCM) group (n = 16) and the western medicine (oral administration with famotidine 0.5 mL + almagate suspension 0.3 mL per mouse, once a day) group (n = 16). After the standard administrating, such objective indexes as general condition, weight, changes in health score, pathology and expression of inflammatory factors were observed to evaluate the efficacy.

RESULTThe radioactive duodenitis model of mice was successfully established with 12 Gy. Mice in the control group suffered from weight loss, anorexia, low fluid intake, loose stools, and occasionally mucous bloody stool, poor spirit, dim fur, lack of exercise and arch back. Mice in drug intervention groups were generally better than those in the pure irradiation group. The IL-6, IL-1beta, TNF-alpha mRNA expressions in spleen and mesenteric lymph node tissues in TCM and western medicine groups showed a declining trend compared with the control group. Their concentrations in peripheral blood serum also slightly changed. The TCM group revealed notable advantage in reducing inflammatory factors. The microscopic observation showed that a better mucosa repair in intervention groups than the pure irradiation group. The improved Chiu's scoring method showed a statistical significance in the difference between TCM and western medicine groups (P < 0.05).

CONCLUSIONLiujunzi decoction combined with Zuojin pills could treat acute radiation enteritis, regulate organic immunity, and inhibit acute injury, promote local tissue repair, with the potential to resist such adverse effects as radiation intestinal fibrosis. The regulation of inflammatory factor release is one of efficacy generation mechanisms.

Background Researches demonstrated that corneal dystrophy is associated with the mutation of transforming growth factor beta induced gene(TGFBI)located at chromosome 5q31 domine.Recent study showed that the gene mutation location is in R124H of TGFBI gene. Objective This study was to identify the mutation characteristics of TGFBI gene in a Chinese family with Avellino corneal dystrophy. Methods This Chinese family with Avellino corneal dystrophy were determined and surveyed in Peking University Third Hospital.Periphery blood from 8 patients with Avellino corneal dystrophy and 2 unaffected subjects were collected from a Chinese family with corneal dystrophy for the extraction of DNA.Exons 4,11,12 of the TGFBI gene were amplified by polymerase chain reaction(PCR),and the amplified products were sequenced directly and compared the gene sequence with that of TGFBI in GenBank.Written informed consent was obtained from each Subject prior to any medieal process. Results This family included 27 members of consecutive 4 generation.The hereditary pattern W88 in accordance with the autosomal dominant inheritance.Directly sequencing of 8 affected members revealed a G tO A transition at codon 124 (CGC to CAC),producing R124H mutation of TGFBI gene.Two synonymous single nucleotide polymorphism(SNP)of TGFBI gene occurred in the family.including a C to T transition at eodon 472(CTC to CTT)in 8 members,and a T to C transition at codon 540(TTT>TTC)in 9 members,which wag unrelated with disease. Conclusion R124H mutation of the TGFBI gene is found in this Chinese family with Avellino corneal dystrophy.

We present a rare case of colonic metastasis of renal cell carcinoma (RCC) and review the literature.A 54-year-old male was referred to our hospital with a history of bloody stools and fever.A dght kidney tumor measuring about 10 cm in diameter was found by abdominal computed tomography.Right radical nephrectomy and a right hemicolectomy with ileotransversostomy were performed.Pathological diagnosis was chromophobe RCC with sarcomotoid change involving the colon.Chromophobe RCC with sarcomotoid change is very rare.

Objective To investigate the better regimen of combined cyclophosphamide pulse therapy with corticosteroids in the treatment of Pemphigus. Methods Intravenous cyclophosphamide was given weekly in a dosage of 600 mg to those Pemphigus patients whose conditions couldn't be improved by corticosteroids (oral prednisone 1.2～1.5 mg/kg/d) alone. Results Ten patients with Pemphigus received weekly cyclophosphomide therapy in addition to corticosteroid. Patients conditions improved quickly, without side effects. Conclusions Cyclophosphamide weekly pulse therapy combined with corticosteroids is a good regimen in the treatment of Pemphigus.

OBJECTIVETo evaluate the effect of the compound of Dan-shen root and azone for scar treatment.

METHODSThe rat skin in vitro and the human skin in vitro and vivo were separately examined their permeability of the mixture of the Dan-shen root and azone. The 301 patients with hypertrophic scar were randomly divided into two groups: one treated with elastic cloth paste (including silicone) contained in Dan-shen root with azone, and the another treated with only elastic cloth paste (including silicone).

RESULTSThe permeability of Dan-shen root with azone, passing through the rat skin in vitro and the human skin in vitro and vivo was significantly higher than both the distilled water and the normal saline (P < 0.05). In the clinical study for treatment of the hypertrophic scars, the efficient rate of the group with the Dan-shen root with azone was significantly higher than the control (91.4% vs. 71.3%) (P < 0.01).

CONCLUSIONThe Dan-shen root with azone could be easier to permeate the skin and more effective to treat the hypertrophic scar.

OBJECTIVETo study the possible immunological mechanism of wheezing attack in children with cytomegalovirus (CMV) infection.

METHODSA total of 25 under-5-year-old children with wheezing following CMV infection were enrolled. The expression of serum regulatory T cells (Treg)/T helper 17 (Th17) cytokines interleukin (IL)-10, IL-6, and IL-17, and peripheral blood lymphocyte subsets were determined. Twenty age-matched healthy children were selected as the control group.

RESULTSThe wheezing group had a significantly reduced serum IL-10 level, significantly increased IL-6 and IL-17 levels, significantly reduced levels of natural killer cells, and significantly increased levels of CD8+ T cells and CD19+ B cells, as compared with the control group.

CONCLUSIONSWheezing children with CMV infection have Treg/Th17 imbalance and cellular immune dysfunction, which may be an important immunological mechanism of the development of wheezing in children after CMV infection.

OBJECTIVETo investigate the incidence rate of anterior knee pain after total knee arthroplasty (TKA) and identify the related factors.

METHODSThis prospective, double-blind clinical trial involved a total of 128 patients scheduled for primary ipsilateral cemented three-component TKA for osteoarthrosis. The patients were randomized into two groups to receive operations for TKA with patellar resurfacing (experimental group) or not (control). The incidence of anterior knee pain was observed in these patients and the factor affecting the occurrence of anterior knee pain and knee was analyzed.

RESULTSThe patients were followed up for a mean of 16.5 months (range 6~24 months). The incidence rate of anterior knee pain was 10.9% (7/64) in the experimental group, showing no significant difference from the rate of 14.1% (9/64) in the control group. But the 52 patients with varus or valgus knee showed a significantly higher incidence rate of anterior knee pain (21.2%, 11/52).

CONCLUSIONTKA with patellar resurfacing can not decrease the incidence of anterior knee pain, and varus or valgus before the operation is associated with a higher risk of anterior knee pain.

Chinese medicinal authentication is fundamental for the standardization and globalization of Chinese medicine. The discipline of authentication addresses difficult issues that have remained unresolved for thousands of years, and is essential for preserving safety. Chinese medicinal authentication has both scientific and traditional cultural connotations; the use of scientific methods to elucidate traditional experience-based differentiation carries the legacy of Chinese medicine forward, and offers immediate practical significance and long-term scientific value. In this paper, a path of inheritance and innovation is explored through the scientific exposition of Chinese medicinal authentication, featuring a review of specialized publications, the establishment of a Chinese medicine specimen center and Chinese medicinal image databases, the expansion of authentication technologies, and the formation of a cultural project dedicated to the Compedium of Materia Medica.
