By systematically combing the records of Bladder Meridian of Foot-Taiyang from medical literatures of Zu Bi Shi Yi Mai Jiu Jing (Maxibustion Canon of Foot and Arm), Yin Yang Shi Yi Mai Jiu Jing (Maxibustion Canon of Ying and Yang), Ling Shu Jing Mai (Meridians, a chapter of Miraculous Pivot), Zhen Jiu Jia Yi Jing (A-B Classic of Acupuncture and Moxibustion), Jiu Jing Tu (Illustration of Moxibustion) from Dunhuang, it can be found that the formation and development of theory of main and collateral channels is a long-term dynamic process containing constantly summing up the experiences. The record about only the 2.3 inch one-line loop route carved out beside the posterior midline of dorsal lumbosacral portion by Bladder Meridian Foot-Taiyang may be a positioning mode of acupoint exclusively used by moxibustion and summed up by people good at moxibustion therapy using their clinical experience. In addition, thoughts that the heavy-moxibustion is a good method for difficult miscellaneous diseases (especially for the serious illnesses after attacked by wind and cold pathogens) may be included.

Objective To determine whether dopamine D5 receptor (D5R) regulates the development of dilated cardiomyopathy (DCM) by inhibiting oxidative stress.Methods We developed heart-specific hD5 mutant (α-MHC-hD5F173L) and wild type (α-MHC-hD5WT) transgenic mice.The NOX2 expression and ROS production were tested in the transgenic mice at three month of age.The α-MHC-hD5F173L mice were treated with either NADPH oxidase inhibitor Apocynin (1mmol/kg/day) or phosphate-buffered saline (PBS) as control by intraperitoneal injection for 4 weeks.After then, the indexes of heart function were measured.The hD5WT and hD5F173L were transfected respectively in rat H9C2 cells, in which ROS production and NOX2 expression were detected at basal level.Results The ROS production and NOX2 expression were higher in the heart of α-MHC-hD5F173L than α-MHC-hD5WT mice.Apocynin treatment improved the heart function of α-MHC-hD5F173L mice.NOX2 expression and ROS production were higher in hD5F173L than hD5WT transfected H9C2 cells.Conclusions Dopomine D5 receptor may prevent DCM development by inhibiting oxidative stress.

Objective To investigate the protective effect of fibrauretin injection against acute lung injury induced by lipopolysaccharide (LPS) in mice.Methods Seventy-two healthy male adult Kunming mice were randomly divided into 6 goups:normal control group,LPS group (intratracheal instilation of 5 mg/kg of LPS),hydrocortisone group (intraperitoneal injection of 3.3 mg/kg of hydrocortisone,once daily for 3 days,and intratracheal instilation of 5 mg/kg of LPS on the 4th day) and low dose,medium dose and high dose of fibrauretin groups (intraperitoneal injection of 2,10 and 50 mg/kg of fibrauretin,respectively,once daily for 3 days,and intratracheal instilation of 5 mg/kg of LPS on the 4th day).The mice in each group were sacrificed by dislocation 24 h after intratracheal instilation of LPS.The lung tissues of partial mice in each group were extracted and weighed to calculate the lung coefficients,and bronchoalveolar lavage (BAL) was performed in partial mice in each group to collect the BALF for counting the inflammatory cells.Results The lung cofficients of mice in LPS group were significantly higher than those in the normal control group (P＜0.05).The lung cofficients of mice in hydrocortisone group,low dose,medium dose and high dose of fibrauretin groups were significantly lower than those in LPS group (P ＜ 0.05).For the percentage of inflammatory cells in BALF and the percentage of neutrophils in inflammatory cells,LPS group was significantly higher than the normal control group (P＜0.01),and compared with LPS group,hydrocortisone group,low dose,medium dose and high dose of fibrauretin groups were significantly decreased (P＜0.01).Conclusion Fibrauretin injection can significantly ameliorate the inflammatory reaction degree in mice with acute lung injury induced by LPS.

The offspring generated by assisted reproductive technology(ART)are considered genetically identical with those generated by natural fertilization. However,studies have found that there are differences between them in some phenotypes to varying extents. In this review, we have summarized the effects of ART on the sex ratio, growth and development,behavior,life expectancy, metabolism of organs and tissues, and molecular phenotypes of mice, providing some guidance to the problems that may arise during the application of ART in the production of genetically modified mice, rapid propagation,purification,embryo cryopreservation,and so on.

Objective:To investigate the serum thyroglobulin (Tg) levels of women in early pregnancy in Dali City, Yunnan Province, and provide a scientific basis for evaluation of individual iodine nutrition of early pregnant women in this area.Methods:Dali City, Yunnan Province was divided into 5 sampling areas according to east, west, south, north and middle. One township (town) was selected from each area, and at least 20 women in early pregnancy were selected from each township (town) as survey subjects. General condition and medical history of all subjects were collected, and random urine samples and fasting venous blood samples were collected for determination of urinary iodine and thyroid function indexes, and a portable ultrasound machine was used for thyroid ultrasonography. After excluding the patients with a history of thyroid disease and abnormal thyroid function, the level of Tg in the included early pregnant women was analyzed.Results:A total of 120 women in early pregnancy were investigated, aged from 19 to 40 years. Among them, 61 cases came from urban areas and 59 were from rural areas. The median urinary iodine was 156.54 μg/L, which was at the appropriate level of iodine nutrition. A total of 102 women with normal thyroid function in early pregnancy were included, and the Tg level was 11.56 (6.67, 15.27) ng/ml. Among them, 58 cases were in urban areas and 44 cases were in rural areas. There was no significant difference in serum Tg levels between rural and urban women in early pregnancy ( U = 1 362.50, P = 0.559). Conclusion:The serum Tg level of women in early pregnancy in Dali City can provide a reference for evaluation of individual iodine nutrition of relevant populations in this area.

Objective:To investigate and analyze the prevalence of thyroid disease during pregnancy in Dali, Yunnan Province, and to provide scientific basis for prevention and treatment of benign thyroid disease during pregnancy in the region.Methods:From July to December 2014, Dali in Yunnan Province was divided into 5 sampling areas according to east, west, south, north and middle. One township (town) was selected from each area, and at least 20 women in early, middle and late pregnancy, respectively, were selected from each township (town). To conduct this investigation, medical history data was collected, thyroid ultrasound examination and serological indexes of thyroid function test were performed based on the normal reference value of specific thyroid function serological indexes during pregnancy in this region.Results:A total of 370 cases of pregnant women were investigated, including 120 cases in early pregnancy (61 cases in urban areas and 59 cases in rural areas), aged 19 - 40 years; 126 cases in middle pregnancy (60 cases in urban areas and 66 cases in rural areas), aged 19 - 45 years; and 124 cases in late pregnancy (57 cases in urban areas and 67 cases in rural areas), aged 19 - 44 years. The detection rate of thyroid disease in pregnant women was 27.57% (102/370). The detection rate of thyroid dysfunction was 7.57% (28/370), the positive detection rate of thyroid antibody was 11.62% (43/370), and the detection rate of thyroid nodule was 13.51% (50/370). The detection rates of thyroid diseases in early, middle and late pregnancy were 33.33% (40/120), 23.02% (29/126), 26.61% (33/124), respectively, and the difference was not statistically significant(χ 2 = 3.362, P > 0.05). Conclusions:In Daliy, Yunnan Province, there is a high detection rate of thyroid diseases during pregnancy, especially in early pregnancy. Therefore, it is necessary to carry out further large-scale investigation and study to provide a more reliable scientific basis for prevention and treatment of thyroid disease during pregnancy in this region.

The setting and adjustment of ventilator parameters need to rely on a large amount of clinical data and rich experience. This paper explored the problem of difficult decision-making of ventilator parameters due to the time-varying and sudden changes of clinical patient's state, and proposed an expert knowledge-based strategies for ventilator parameter setting and stepless adaptive adjustment based on fuzzy control rule and neural network. Based on the method and the real-time physiological state of clinical patients, we generated a mechanical ventilation decision-making solution set with continuity and smoothness, and automatically provided explicit parameter adjustment suggestions to medical personnel. This method can solve the problems of low control precision and poor dynamic quality of the ventilator's stepwise adjustment, handle multi-input control decision problems more rationally, and improve ventilation comfort for patients.
