2. Advances in mechanisms of traditional Uygur medicine on inflammatory bowel disease
Chinese Traditional and Herbal Drugs 2017;48(11):2327-2334
Inflammatory bowel disease (IBD) is a common gastrointestinal disease in which the etiology and pathogenesis are still unclear. Generally speaking, it is caused by environment, inheritance, and immune. The related factors include immune system, oxidative stress, microflora in gastrointestinal tract, NF-κB, NO, COX-2, LB4, and the correlation factors. There are many plants that are effective to inflammatory bowel disease in traditional Uygur medicine, such as Solanum nigrum, Quercus infectoria, and Punica granatum. For some of these plants, only one or two mechanisms of action have been found. Besides, some constituents of them are effective to anti-inflammatory bowel disease. This article reviewed the role of factors in IBD and the mechanism of anti-inflammatory bowel disease of traditional Uygur medicine.

α-thalassemia is a type of microcytic hypochromic anemia caused by variants of alpha-globin gene, and is one of the most common monogenic disorders in southern China. The population screening model based on hematologic phenotype has achieved great results in areas with high incidence of thalassemia. However, with the continuous decline of the cost of genetic testing and implementation of screening programs for thalassemia gene carriers, more variants in the alpha-globin gene have been discovered, which also brings great challenges to clinical genetic counseling. From the perspective of alpha-globin genetic analysis, this consensus has discussed the contents of pre- and post-test genetic counseling, with an aim to provide standardized guidance for clinicians.

A HPLC method of analysis of Monascus citrinin was established. More than 30 strains of Monascus spp. were cultured in steamed rice at solid state or in MSG liquid medium composed of monosodium glutamate as sole nitrogen source and glucose as sole carbon to investigate their ability of producing citrinin. The results indicated that most of the Monascus strains are able to produce citrinin. MSG medium can be used as a specific culture medium to qualitatively identify if the strain is the potential citrinin producer. But to confirm whether the Monascus strains are potential citrinin producers, these strains should be cultured in several cultivation methods, as the culture states and culture conditions influence the citrinin production greatly.

San'ao Decoction (SD) and its analogous formulas derived in the following generations are common used prescriptions for treating pulmonary diseases with principal symptoms such as cough and asthma. They are usually compatible with Chinese herbs for facilitating Fei, dispelling wind, resolving phlegm and fluid retention. Material bases in these formulas are mainly derived from Chinese drugs, but dissolution contents of active components are changed and new components are produced after compatibility. By multilevel effect evaluation, these analogous formulas all have commonness in ventilating Fei and superiorities of evidence-based derivation. The effect pathway of commonness was involved in cell structure protection, anti-inflammation, antioxidant, and immunoregulation.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.
METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.
RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).
CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

OBJECTIVETo observe analgesic and sedative effect of acupuncture combined with medicine (ACM) on patients undergiong cardiac surgery.
METHODSA total of 50 patients with cardiac surgery from January 2012 to October 2014 were randomly assigned to the conventional analgesia group (group A) and the ACM analgesia group (group B), 25 in each group. Patients in group A were subjected to analgesia and sedation by injecting dexmedetomidine, while patients in group B were subjected to analgesia and sedation by electro-acupuncture [EA, Shenting (GV24); Yintang (EX-HN3)] combined with injection of dexmedetomidine. Morphine hydrochloride injection was performed when analgesia and sedation effect was ineffective in the two groups. The indicators of patients at different time points in the two groups were observed, such as static and dynamic VAS scores, SAS scores, mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2). The injection dosage of dexmedetomidine and morphine hydrochloride, analgesia satisfaction rate, sedation satisfaction rate, the incidences of adverse reactions during treatment such as bradycardia and low blood pressure, mechanical ventilation time, ICU time, and hospitalization expense were observed and recorded in the two groups.
RESULTSThere was no statistical difference in static and dynamic VAS scores, SAS score, MAP, HR and SpO2 between the two groups at different time points (P > 0.05). The injection dosage of dexmedetomidine and morphine hydrochloride was significantly reduced in group B than in group A (P < 0.05). The analgesia satisfaction rate of patients in group B was much higher than that in group A (P < 0.05). The incidence of bradycardia also obviously decreased more in group B than in group A (P < 0.05). There was no statistical difference in patients' sedation satisfaction rate, incidences of low blood pressure, delirium, vomiting; mechanical ventilation time, ICU time, or hospitalization expense between the two groups (P > 0.05).
CONCLUSIONThe analgesia method of ACM could reduce the dosage of traditional analgesic drugs and the occurrence of partial adverse reactions.

Background Chondroitin sulphate proteoglycans (CSPGs) can cause the termination of ocular dominance plasticity in the visual cortex.Recently,protein tyrosine phosphatase σ (PTPσ) has been identified as a receptor that inhibits CSPGs.However,whether PTPσ and its downstream molecules participate in the reactivation of ocular dominance plasticity in adult visual cortex has not been studied.Objective The present study was to investigate the changes in the expression of the PTPσ,probabilistic neural networks (PNNs),and molecules downstream of PNN,such as N-cadherin/β-catenin,after the reactivation of adult visual cortical plasticity.Methods Fifty-four SPF Long Evans rats were grouped according to different postnatal week (PW) as the PW1 (6 rats),PW3 (6 rats),PW5 (6 rats),PW7 (24 rats),and PW9 (12 rats) groups,and the upper and lower eyelids were sutured in the 12 rats from the PW7 group for 14 days to establish the binocular plasticity reactivation models.Expression of PTPσ and PNNs in the rat visual cortex was detected using immunochemistry,and changes of PTPσ mRNA,N-cadherin mRNA and β-catenin mRNA expression in the rat visual cortex with plasticity reactivation were assessed by real-time fluorescence quantitative PCR (RT Q-PCR).The use of animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The expression level of PTPσ mRNA was significantly higher in the PW9 group than that of the binocular plasticity reactivation models and the PW7 group (t =1.965,3.526,P<0.01).The staining of the rat visual cortex for PTPσwas localized to the cellular membrane,cytoplasm and axon.Cell densities of the PW9 group in the Ⅱ-Ⅲ layer,Ⅳ layer and Ⅴ-Ⅵ layer of the visual cortex were elevated in the PW9 rats compared with the PW7 rats (t =24.593,23.444,13.556,P<0.01) and rats from the binocular plasticity reactivation model (t =44.111,43.000,16.556,P<0.01).Cell densities for PNNs in the Ⅳ and Ⅴ-Ⅵ layers were significantly increased in the PW9 rats in comparison with the PW7 rats (t=1.926,P<0.01 ;t=1.370,P<0.05),but the cell density in the Ⅱ-Ⅱ layer has no statistical significance (t=0.889,P>0.05).However,cell densities for PNNs in the Ⅱ-Ⅲ and Ⅳ layers in the binocular plasticity reactivation models were lower than those of the PW9 rats (t =2.556,4.585,P<0.01).Compared with PW1 rats,the expression levels of the N-cadherin mRNA in the PW3,PW5,PW7,PW9 rats were lower (t =28.932,28.988,27.083,28.908,P<0.01),but those in the PW7 rats were enhanced in comparison with the PW3 rats,PW5 rats and PW9 rats (t =1.848,1.904,1.825,P<0.01).No significant difference was seen in the expression of the N-cadherin mRNA between the PW9 rats and rats from the binocular plasticity reactivation model (t =0.072,P>0.05).A statistically significant increase was found in the β-catenin mRNA expression in the PW1 rats compared with the PW3,PW5,PW7 and PW9 rats (t =3.918,3.534,2.645,4.652,P< 0.0 1),as well as between rats from the binocular plasticity reactivation model and the PW9 rats (t =0.570,P<0.01).Conclusions PTPr,PNNs and β-catenin are involved in the reactivation of ocular dominance plasticity in the adult visual cortex.
