The diabetes is mainly treated by the oral administration of western medicines at present. Despite their rapid curative effect, there have been still many reports for the western medicines about their clinical adverse reactions, failure of effective prevention and treatment of complications and drug resistance. Hence, they are not suitable for long-term administration. Traditional Chinese medicines have a long history in treating diabetes mellitus (DM) , which is commonly known as Xiaokezheng in the theory of traditional Chinese medicines. In recent years, many scholars have taken extracts from traditional Chinese medicines or separated active constituents as the study objects in the expectation of developing new-type drugs for treating and preventing diabetes. Therefore, a large number of study reports have been emerged in this field. Due to their significant glucose-reducing effect and specific effect in treating complications of diabetes, traditional Chinese medicine Gardeniae Fructus and its iridoid component geniposide shall be given full attention. This paper summarized the advance in studies on the curative effect and action mechanism of Gardeniae Fructus and geniposide in preventing and treating diabetes.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

Objective To investigate the effect of leflunomide on the superficial costimulatory molecules expression of T lymphocytes in patients with lupus nephritis ( LN ). Methods The peripheral blood mononuclear cells (PBMCs) of female active LN patients and healthy female were separated by density gradient centrifugation, and cultured by phytohemagglutinin (PHA) or leflunomide active metabolites(A771726).The CD28, CD40L, CTLA-4 and LFA-1a expressions on the peripheral blood T lymphocytes were detected by double-colored flow cytometry. The differences of the means were tested by analysis of variance( ANOVA ) and SNK q test. Results Comparing with healthy controls, there were significantly higher expressions of CD28,CD40L, LFA-1a and CTLA-4 on the peripheral blood T cells in active LN patients (CD28:33.4±6.5 vs14.4±3.2; CD40L: 13.2±3.2 vs 5.4±2.3; LFA-1a: 8.5±2.3 vs2.2±1.1; CTLA-4:4.6±1.5 all P<0.01) as well as CD28 and CD40L expression on the peripheral blood T cells from healthy controls induced by PHA (CD28:26.8±6.7 vs14.4±3.2; CD40L: 13.9±4.9 vs 5.4±2.3 all P<0.01 ), but not CTLA-4 and LFA-1a expression.However, CD28, CD40L, LFA-1a and CTLA-4 expressions on T cells stimulated by PHA increased in active LN patients(all P<0.05 ). A771726 could significantly inhibit over-expression of LFA-1a and CD40L on the T cells from active LN patients (CD40L:8.2±2.0 vs13.3±3.2;LFA-1a:5.1±1.3 vs8.5±2.3 all P<0.01 ), but not CD28 and CTLA-4 expression. A771726 did not inhibit CD28, CD40L, LFA-1a and CTLA-4 expression on the T cells in healthy controls. Furthermore, A771726 could markedly inhibit the over-expression of all of the above molecules induced by PHA on the T cells of active LN patients (all P<0.05). Conclusion One of the major mechanisms for LEF treatment of LN is that LEF can down-regulate CD40L and LFA-1a expression but not CD28 and CTLA-4 expression on the peripheral blood T cells in active LN patients.

Objective To analyze the outcomes and prognostic factors associated with the death of systemic lupus erythematosus (SLE) patients admitted to the intensive care unit (ICU). Methods During June 1996 to June 2007, all SLE patients admitted to the ICU were included. Patients were excluded if the diagnosis of SLE was established at or after ICU admission. A multivariate logistic regression model was applied using variables that were associated with death in the univariate analysis. Results A total of 101 patients meeting the criteria were included. The mortality rate was 48.6%. The most common causes of admission was lung disorder with acute respiratory distress syndrome (ARDS). Multivariate logistic regression analysis suggested that SLICC/ACR DI>7.7 (OR=6.87), APACHE Ⅲ≥21 (OR=29.8), lung disorders with ARDS (OR =55.81 ), septic shock (OR =32.22 ), intracranial haemorrhage (OR =57.35 ), hypocytopenia (OR = 5.89), mean equivalent prednisone dose>25 mg/d (OR=7.65) and prolonged tracheal intubation (OR=5.98) were signi-ficantly associated with death. Whereas sex, age, SLEDAI >27, gastrointestinal bleeding, the cumulative dosage of CTX higher than 1.0 g, pulse intravenous methylprednisolone therapy were not associated with death. Conclusion The mortality rate of critically ill SLE patients in ICU is very high. SLICC/ACR DI> 7.7, APACHE Ⅲ≥21, lung disorders with ARDS, septic shock, intracraniai haemorrhage, average prednisone equivalent dosage higher than 25mg/d and prolonged tracheal intubation (longer than 4 days) are negative prognostic factors in SLE patients admitted to the ICU.

Acupuncture Research 2019;44(8):599-604
OBJECTIVE: To observe the clinical effect of acupuncture plus medication in the treatment of poor ovarian response (POR) patients and to explore its mechanisms in assisting pregnancy. METHODS: A total of 100 volunteer POR women undergoing in vitro fertilization-embryo transplantation (IVF-ET) were recruited in the present study. On the 1st cycle of IVF-ET, these POR women received microstimulation of ovulation program (oral administration of Clomiphene, muscular injection of Menotrophin, Chorionic Gonadotrophin triggering, etc.). Before receiving the 2nd period of IVF-ET, these patients were equally and randomly divided into control, medication (Climen, composed of estradiol valerate and cyproterone acetate), acupuncture and acupuncture+medication (combined treatment) groups according to the random number table. Patients of the medication group were asked to orally take Climen (1 tablet/d for 21 days) beginning from the 3rd day of the menstruation, which was repeated for 3 menstrual cycles. Patients of the acupuncture group received manual acupuncture stimulation of Guanyuan (CV4), and bilateral Taixi (KI3), Sanyinjiao (SP6) of and Tai-chong (LR3) from day 8 to 15 of menstruation (follicular phase), once daily for 3 menstrual cycles. On the 2nd day of menstruation of the 1st and 2nd IVF-ET cycle, the ovarian reserve function was detected, including measurement of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) contents by using radioimmunoassay, and serum anti-mullerian hormone (AMH) level by using ELISA, and the antral follicles count (AFC) of the ovaries by using a color Doppler ultrasonic diagnosis apparatus. At the end of ovulation induction, the assisted pregnancy indexes and outcomes were detected, including administration of dosage and days of gonadotropin (Gn), the diameter of dominant oocyte, level of E2 on the trigger day, the numbers of ultrasound-guided-retrieved oocyte and the cultivated high-quality embryo (grade 1 and 2). RESULTS: After the treatment, the contents of serum FSH, LH and E2 in the medication, acupuncture and combined treatment groups were significantly reduced (P<0.05), and the content of serum AMH and ovary AFC in the medication, acupuncture and combined treatment groups were obviously increased (P<0.05) in comparison with their own pre-treatment (P<0.05). Compared with the control group, the levels of FSH, LH and E2 contents were notably decreased, and the AMH content and AFC significantly increased in the medication, acupuncture and combined treatment groups (P<0.05). Comparison among the three treatment groups showed that the levels of FSH, LH and E2 were notably lower in the combined treatment group than in the acupuncture group (P<0.05), and the AFC was markedly more in the combined treatment group than in the acupuncture group (P<0.05), and LH content was also significantly lower in the combined treatment group than in the medication group (P<0.05). Regarding the pregnancy-assistant indexes and outcomes, the dosage of Gn in the combined treatment group and the number of Gn administration days in the acupuncture and combined treatment groups were significantly fewer (P<0.05), serum E2 levels on the trigger day in the medication, acupuncture and combined treatment groups, and the high-quality embryo number in the combined treatment group were considerably higher in comparison with their own levels of the 1st IVF-ET cycle in each group (P<0.05). Comparison among the three groups showed that the dosage and number of administration days of Gn in the combined treatment group were fewer than those in the medication group(P<0.05), and the dosage of Gn in the combined treatment group were significantly lower than that in the acupuncture group (P<0.05), E2 content of the combined treatment group was markedly higher than that of the medication and acupuncture groups (P<0.05). The high-quality embryo number in the combined treatment group was obviously larger than that of the medication group (P<0.05). No significant differences were found between the 2nd and 1st IVF-ET cycles in the number of the obtained oocyte, between the acupuncture and medication groups in the E2 content at the trigger day, and the numbers of Gn administration days and the high-quality embryo (P>0.05). CONCLUSION: Acupuncture combined with medication improves the level of endocrinal hormones and ovarian reservation function in POR women undergoing IVF-ET, benefiting the ovary environment of pregnancy.
