To investigate the clinical risk factors of cardiac diastolic dysfunction in type 2 DM, Doppler echocardiographic examinations were performed on 63 male patients.With a routine 2 dimensional echocardiograph, mitral and pulmonary venous flow velocity were recorded. The patients were classified into DM, IGT and NGT based on well standardized criteria of WHO. All analyses were performed by the SPSS/PC or Windows Release 9.0 Statistical Package. The risk factors of impairment of diastolic function were analyzed by regression. Results showed that the levels of blood glucose and insulin were independent risk factors for diabetic cardiac diastolic dysfunction.

Objective: To compare the chemical constituents in the essential oils from the leaves, flowers, and seeds of Elsholtzia ciliata and their antimicrobial activities. Methods: The chemical constituents in essential oils were extracted by the hydro-distillation method and analyzed by GC-MS. The chemical constituents in essential oils were identified on the basis of comparison on their retention indices and MS spectrum with published data. Moreover, the antimicrobial activities of the chemical constituents in the oils against the growth of six bacteria strains and one pathogenic yeast strain were evaluated by using minimum inhibitory concentration and minimum bactericidal concentration methods. Results: A total of 58 compounds were identified, while compounds 31, 35, and 36 were identified in the essential oils from the leaves, flowers, and seeds, respectively. Fifteen compounds were identified as shared constituents in the leaves, flowers, and seeds. The chemical constituents in the essential oils showed the inhibitory activities against the six bacteria strains and the yeast strain. Conclusion: The major constituents are different in the essential oils of the leaves, flowers, and seeds. The major chemical constituents in the essential oils are monoterpenoids and sesquiterpenoids. And the chemical constituents in the essential oils obtained from the leaves show higher inhibitory activities especially against Bacillus subtillis CMCC63501 and Escherichia coli ATCC25922. © 2013 Tianjin Press of Chinese Herbal Medicines.

Objective The aim of this study was to determine if isoflavone genistien has protective effects against high glucose-induced cell apoptosis in human aortic endlthelial cells,and investigate the possible mechanism for this protection.Methods Human aortic endothelial cells subjected to normal (5mmol/L) or high glucose (25mmol/L) were treated with genistein at 0,50,100nmol/L.Parallel experiments were performed with 100nM 17b-estradiol,and also in the presence and absence of the pure anti-estrogen ICI-182,780 (100nmol/L).The effects on cell apoptotic DNA fragmentation were determined using cell death ELISA,and the effects on cellular proliferation were determined using tritiated thymidine incorporation assay.Estrogen receptor expression was detected by Taqman quantitative PCR.Results Genistein at 100nmol/L significantly reduced high glucose-induced DNA fragmentation,and reversed cell DNA synthesis inhibition (P＜0.001) after 24 hours' incubation.The effect of genistein was completely blocked by ICI-182,780administration.Estrogen receptor beta,but not alpha was found to be expressed in these cells.Conclusion Isoflavone genistein shows protection against high glucose-induced cell damage through estrogen receptor beta,reducing apoptotic DNA damage and protecting from the inhibition of cell proliferation.

Objective: To observe the effect of acupoint massage plus Vitalstim electrical stimulation on deglutition function and surface electromyography (SEMG) of deglutition muscle groups. Methods: A total of 60 patients with deglutition disorder after stroke were selected and divided into an electrical stimulation group, a massage group and an integrated group according to the random number table method, with 20 cases in each group. Patients in these three groups were given the same routine rehabilitation training for deglutition. In addition, patients in the electrical stimulation group were given extra Vitalstim electrical stimulation, patients in the massage group were given extra acupoint massage on the head, face and neck, and patients in the integrated group were given extra acupoint massage plus Vitalstim electrical stimulation. Fujishima Ichiro food intake level scale (FILS) was scored before and after treatment. The swallowing duration and maximal amplitude of masseter muscle in SEMG were evaluated before and after treatment. Results: After treatment, the FILS score and the maximal amplitude of recruitment potential generated by muscular contraction of masseter muscle group in the three groups were higher than those before treatment (all P<0.05), and the swallowing duration of masseter muscle group was shortened compared with that in the same group before treatment (all P<0.05). After treatment, the FILS score in the integrated group was higher than that in the electrical stimulation group and the massage group (both P<0.05). The swallowing duration of masseter muscle group measured by SEMG was lower than that in the electrical stimulation group and the massage group (both P<0.05), while the maximal amplitude was higher than that of the electrical stimulation group and the massage group (P<0.05). After treatment, there were no significant differences in the FILS score, swallowing duration and maximal amplitude of masseter muscle group between the electrical stimulation group and the massage group (all P>0.05). Conclusion: Both acupoint massage and electrical stimulation can improve the deglutition function in patients with deglutition disorder after stroke, and improve the coordination and flexibility of masseter muscle. The integration of the two is more effective.

OBJECTIVETo report the experiences of the diagnosis and treatment of primary lymphoma of the small intestine (PSIL).

METHODSThe clinical data of 15 patients with PSIL treated from January 2003 to July 2007 was investigated retrospectively. Of the 15 cases, 9 patients were male and 6 were female, the average age was 51.6 years (range, 18 - 73 years). Data of gender, age, clinical manifestation, laboratory examination, imageology examination, diagnosis and treatment of the patients was reviewed.

RESULTSThe most common clinical manifestations were as follow: abdominal pain, abdominal lump, bowel obstruction, gastrointestinal hemorrhage and athrepsy. Serum tumor markers were checked normal. All the 15 cases were found with tumor by spiral CT, and 12 cases were diagnosed as PSIL. Eleven cases were given Ba-meal examinations, and positive results was found in 4 cases, and only 1 case was considered to be PSIL. All the 15 patients received operation. All the patients were diagnosed as non-Hodgkin lymphoma (NHL) by postoperative pathology (8 patients as diffuse large B-cell lymphoma, 5 as mucosa associated lymphoid tissue type B cell lymphoma and 2 as enteropathy-type intestinal T cell lymphoma). No perioperative death occurred. Ten patients received adjuvant chemotherapy with the regimen of CHOP (cyclophosphamide + epirubicin + vincristine + prednisone) after the operation. Fourteen cases were followed-up for a mean time of 30 months (range, 6 - 52 months). The 1- and 3-years survival rate was 85.7% and 57.1%, respectively.

CONCLUSIONSPSIL has no specific clinical manifestations, the diagnostic rate with barium study is low, spiral CT scan is a promising diagnostic method for PSIL. Operation combined with chemotherapy is important for PSIL.

Objective To evaluate the differentiation-inducing effect of phenylacetate on pancreatic carcinoma cells and underlying mechanism of RNA editing deaminase in cell proliferation and differentiation. Methods The effect of phenylacetate on cell proliferation and cell cycle were investigated in cultured pancreatic carcinoma BXPC-3 cell lines by methylthiazoletetrazolium( MTT) assay, and flow cytometry. The effect of phenylacetate on the expression of RNA editing deaminase (ADAR2 mRNA) in BXPC-3 cells and fresh pancreatic carcinoma specimen was evaluated by RT-PCR. Results ADAR1 mRNA expression was positive in human pancreatic carcinoma tissues and BXPC-3 cell lines. After application of 1.0 and 2.0 mmol/L phenylacetate for 24 h and 72 h, BXPC-3 cell growth inhibition rate increased, G0/G1 phase cells decreased, S phase cells increased, ADAR2 mRNA expression decreased ( P < 0.01 ). Conclusion ADAR2 mRNA played a vital role of regulation in the process of pancreatic carcinoma cells growth and differentiation. Phenylacetate could regulate the proliferation and differentiation of pancreatic carcinoma cells through the regulation of ADAR2 mRNA expression.

BACKGROUNDSymbrachydactyly is defined as a combination of short fingers with syndactyly. There are few published reports estimating the incidence of symbrachydactyly. The aim of this study was to investigate the clinical features and the outcome of surgical treatment for congenital symbrachydactyly.

METHODSOne hundred and twenty webs of thirty-four patients of symbrachydactyly were involved in the study. The sex ratio was 21 males/13 females. The age ranged from 1 year to 8 years, average 2.6 years. Four cases had both hands involved and 30 patients had one hand involvement. Release of the syndactylous digits webs were completed by one surgical procedure in 14 cases and more than one surgical procedure in 20 cases; 3 to 6 months between the procedures. In the meantime, some of the associated hand deformities were treated.

RESULTSPostoperative follow-up time was 10 to 18 months, average 12 months. All the fingers involved in this study were separated successfully. However, 6 fingers had scar tissue contracture and 8 had web scar adhesion. All complications needed further surgical treatment. Parents of 94.1% of the patients were satisfied with the overall function of the hand, and 76.5% were satisfied with the cosmetic appearance of hand.

CONCLUSIONSThe combination of syndactyly and brachydactyly is the main clinical feature in symbrachydactyly. Separation of the digital webs can greatly improve the function of the hand. However, more work needs to be done to improve the cosmetic appearance of the hand.

OBJECTIVETo observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

METHODSTotally 50 SD rats were randomly divided into five groups, i.e., the blank control group, the sham-operation group, the model group, the Chinese medicine (CM) group, and the Western medicine (WM) group, 10 in each group. Rats in the blank control group and the sham-operation group were fed routinely. Rats in the rest 3 groups received 30-day "extended refrigerator freezing and ice water immersion" and combined with " autotransplantation" to establish EM rat model with SYDBSS. One Milliliter BWHR at 3.33 g/mL was administered to rats in the CM group by gastrogavage. Gestrinone at the daily dose of 0. 5 mg/kg was administered to rats in the WM group by gastrogavage. Equal volume of normal saline was administered to rats in the model group, the blank control group, and the sham-operation group. The size and morphology of ectopic foci in rats were observed after 4 weeks of medication. Expressions of serum CA125, plasma cyclic adenosine monophosphate (cAMP), and plasma cyclic guanosine monophosphate (cGMP) were detected by radioimmunoassay. Morphological changes of eutopic endometrium and ectopic tissue were observed under the optical microscope by HE staining. Protein expressions and contents of HIF-lα, PHD2, and VHL were detected by immunohistochemical SABC method and Western blot. mRNA expressions of HIF-1α, PHD2, and VHL were detected by RT-PCR.

RESULTSThe ectopic foci grew significantly in the model group. Their volumes were obviously contracted after treated by CM and WM. Compared with the blank control group and the sham-operation group, serum CA125 and plasma cGMP obviously increased, cAMP obviously decreased (P < 0.05); expressions and contents of HIF-1α mRNA and protein all decreased (P < 0.05); mRNA and protein expressions and contents of PHD2 and VHL all decreased in the model group (P < 0.05). Compared with model group, levels of CA125 and cGMP obviously decreased; cAMP levels obviously increased, expressions and contents of HIF-1α mRNA and protein all increased, mRNA and protein expressions and contents of PHD2 and VHL all increased in the WM group and the CM group (P < 0.05). Compared with the CM group, PHD2 protein contents were higher in the WM group (P < 0.05). HIF-1α was negatively correlated with PHD2 (r = -0.799, P = 0.00). HIF-1α was negatively correlated with VHL (r = -0. 625, P = 0.003).

CONCLUSIONSBWHR could effectively treat EM. Its mechanism might be associated with reducing contents of HIF-1α, serum CA125, and plasma cGMP, and up-regulating expressions of PHD2, VHL, and cAMP.

OBJECTIVETo summarize the clinical characteristic and outcome of digital gigantism of the foot.

METHODSRetrospectively analyze the clinical documents of cases of digital gigantism of the foot. Twelve 12 cases with 13 feet in this study included 8 male and 4 female with an average 4.6-years-old. All the deformities were found at birth. Multiple toes involved were more than single toe, and tibial toe involved more than fibular. Forefoot was enlarged. All the phalanges involved and partial metatarsal bones were enlarged. Marked increase in subcutaneous fat was found in all cases in the operation which infiltrated interossei and articular capsules. The appearance of the nerves and its branches in the foot were normal and fat infiltrating was not discovered. The operation types included debulking, epiphyseal arrest, amputation, nerve stripping and anastomosis.

RESULTSSeven cases were followed up with mean periods 25.6 months. Functional evaluation according to a criterion formulated by author revealed a result of 2 excellent, 2 good and 3 fair.

CONCLUSIONSDigital gigantism of the foot is an uncommon congenital deformity of the foot characterized by overgrowth of both the soft-tissue and the osseous elements of the enlarged toe and forefoot. Surgical treatment is the unique method, and the goal is to reduce the size of the foot to allow fitting regular shoes and walking readily. There are several types of operations which to be chosen. The indication, the timing of operative intervention and the selection of operation type should be paid more attention.
