In this paper， by referring to ancient and modern literature， the textual research of Inulae Flos has been conducted to clarify the name， origin， production area， quality evaluation， harvesting， processing and others， so as to provide reference and basis for the development and utilization of famous classical formulas containing this herb. After textual research， it could be verified that the medicinal use of Inulae Flos was first recorded in Shennong Bencaojing of the Han dynasty. In successive dynasties， Xuanfuhua has been taken as the official name， and it also has other alternative names such as Jinfeicao， Daogeng and Jinqianhua. The period before the Song and Yuan dynasties， the main origin of Inulae Flos was the Asteraceae plant Inula japonica， and from the Ming and Qing dynasties to the present， I. japonica and I. britannica are the primary source. In addition to the dominant basal species， there are also regional species such as I. linariifolia， I. helianthus-aquatili， and I. hupehensis. The earliest recorded production areas in ancient times were Henan， Hubei and other places， and the literature records that it has been distributed throughout the country since modern times. The medicinal part is its flower， the harvesting and processing method recorded in the past dynasties is mainly harvested in the fifth and ninth lunar months， and dried in the sun， and the modern harvesting is mostly harvested in summer and autumn when the flowers bloom， in order to remove impurities， dry in the shade or dry in the sun. In addition， the roots， whole herbs and aerial parts are used as medicinal materials. In ancient times， there were no records about the quality of Inulae Flos， and in modern times， it is generally believed that the quality of complete flower structure， small receptacles， large blooms， yellow petals， long filaments， many fluffs， no fragments， and no branches is better. Ancient processing methods primarily involved cleaning， steaming， and sun-drying， supplemented by techniques such as boiling， roasting， burning， simmering， stir-frying， and honey-processing. Modern processing focuses mainly on cleaning the stems and leaves before use. Regarding the medicinal properties， ancient texts describe it as salty and sweet in taste， slightly warm in nature， and mildly toxic. Modern studies characterize it as bitter， pungent， and salty in taste， with a slightly warm nature. Its therapeutic effects remain consistent across eras， including descending Qi， resolving phlegm， promoting diuresis， and stopping vomiting. Based on the research results， it is recommended that when developing famous classical formulas containing Inulae Flos， either I. japonica or I. britannica should be used as the medicinal source. Processing methods should follow formula requirements， where no processing instructions are specified， the raw products may be used after cleaning.

Objective To investigate the effect of GHET1 on the biological behavior of gallbladder cancer cells and the regulatory mechanism of GHET1 on miR-27b. Methods The expression of GHET1 and miR-27b in 50 samples of gallbladder cancer was detected by real-time quantitative PCR. The si-NC vector, si-GHET1 vector, miR-27b inhibitor, and si-GHET1 vector+miR-27b inhibitor were transfected into SGC-996 cells and set as the control group, GHET1 interference group, miR-27b interference group, and GHET1+miR-27b interference group. Cell proliferation, apoptosis, and metastasis in each group were detected by MTT, flow cytometry, and Transwell assays. The regulatory effect of GHET1 on miR-27b was validated by luciferase reporter gene assay. Results GHET1 expression was higher in cancer tissues than that in paracancerous ones. miR-27b expression was lower in cancer tissues than that in paracancerous tissues. GHET1 was negatively correlated with miR-27b expression (P<0.05), and GHET1 expression was associated with TNM staging and lymph node metastasis (P<0.05). High GHET1 expression was associated with poor prognosis of patients with gallbladder cancer (P<0.05). Compared with the control group, the GHET1 interference group showed decreased cell-proliferation ability, increased apoptosis rate, and reduced number of cell metastasis. The miR-27b interference group showed increased cell-proliferation ability, decreased apoptosis rate, and increased number of cell metastasis (P<0.05). Compared with the GHET1 interference group, the GHET1+miR-27b interference group showed increased cell-proliferation ability, decreased apoptosis rate, and increased number of cell metastasis (P<0.05). GHET1 inhibited miR-27b expression by acting as a sponge of miR-27b. Conclusion GHET1 promotes the proliferation and metastasis and inhibits the apoptosis of gallbladder cancer cells by targeting miR-27b, suggesting that GHET1/miR-27b axis plays a role in gallbladder cancer progression.

Objective To investigate the cytidine triphosphate synthetase 1 (CTPS1) expression in pancreatic cancer cell lines and its impaction on prognosis.Methods The GEO profiles database was searched to collect clinical data of 39 patients of pancreatic ductal adenocarcinoma.Kaplan-Meier curve was used to analyze the relationship between the patients' prognosis and the expression of CTPS1.qPCR and Western blot were applied to detect the expression of CTPS1 in 4 pancreatic cancer cell lines.Results The mRNA expression of CTPS1 in Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 1.00) ± 0.20,2.92±0.95,4.29±0.14,and 2.26±0.33 (t=-16.19,-11.45,-8.09,-13.12,P＜0.05) when compared to the normal pancreatic ductal epithelial cell line HPDE of 7.70 ± 0.72.The relative protein expression of CTPS1 in pancreatic cancer cell lines Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 0.40 ± 0.06,0.20±0.09,0.68±0.11,and0.48±0.06 (t=-8.97,-10.5,-4.39,-7.88,P＜0.05) when compared to HPDE of 1.09 ±0.12.The overall survival (OS) in patients with higher CTPS1 expression than adjacent tissue was 28 months (95％ CI:9.2-46.8 months),and that with lower CTPS1 expression was 13 months (95％ CI:8.2-17.8 month),(x2 =4.02,P＜0.05).Conclusions CTPS1 in the pancreatic cancer cell lines are of low expression,and the level is positively related to patients' survival time.

An alternative method based on an off-line solid phase extraction ( SPE ) combined with programmable temperature vaporizer-based ( PTV) large volume injection-gas chromatography-flame ionization detection ( LVI-GC-FID ) was developed. The goal of this study was to determine mineral oil saturated hydrocarbons ( MOSH ) in camellia seed oils. The purification condition of SPE columns with silver impregnated the activated silica gel and activated aluminum oxide was optimized. The optimal SPE cartridge was loaded with 10 g of Ag-activated silica gel per 10 g of activated aluminum oxide. The PTV initial temperature was set at 75℃ for 1 min (split 200:1), and heated from 75℃ to 370℃ at 250℃/min. Then the diverter valve was closed for 1 min and opened again with the split flow ratio changing to 50:1 . The injection volume was 40μL. The calibration curve of paraffin oil was liner in the range of 5-500 mg/kg with correlation coefficient of 0. 998. The detection limit (LOD) and the quantification limit (LOQ) of paraffin oils in hexane were 0. 26 mg/kg and 0. 80 mg/kg, respectively. The recoveries from spiked oil samples were between 93 . 3% and 112 . 7%, with relative standard deviation ( RSD ) of 1 . 8%-5 . 2%, the RSD of intra-day and inter-day were less than 2 . 6% . This procedure was applied to analyze the MOSH in 11 commercial camellia seed oils and the contamination was found to range from 6. 8 mg/kg to 76. 7 mg/kg. The method is simple in operation with high sensitivity, good reproducibility and low cost, and suitable for determination of MOSH in vegetable oils.

Objective Using MR defecography to assess the morphological and functional anorectal anomalies related to female outlet obstruction constipation, and evaluate the joint disease of anterior and mid pelvic. Methods One hundred and seven female patients, aged 20 to 84 years ( average, 55 years), were diagnosed as outlet obstruction constipation based on clinical symptoms and signs. They all received MR defecography in our institution. The high compliance homemade balloon was inserted into rectum to simulate stool Then relevant measurements were obtained during rest, squeezing and straining, respectively. Results In all the 107 cases, 70 ( 65.4% ) presented rectocele on dynamic MRI; 28 ( 26. 2% ) presented anismus;60 (56. 1% ) presented cystocele; 59 presented vaginal or cervical prolapse(55. 1% ); and, 54 (50. 5% )presented descending perineum. In 85 females (79.4%) multiple disorders were detected, involving more than one pelvic compartment. Conclusion MR defecography allowed to accurately evaluate the morphological and functional anorectal anomalies related to female outlet obstruction constipation, and the joint disease of anterior and mid pelvic.

Objective To investigate the characteristic,diagnosis,clinical staging, treatment and clinical prognosis of occult breast carcinoma (OBC). Method Forty-six cases of OBC were analyzed retrospectively with the clinical and follow-up information that were confirmed by postoperative pathologic diagnosis from November 1981 to November 2005. Results All patients showed axillary node enlargement as the first sign and were operated.The operation included axillary node excision in 2 patients,radical mastec-tomy or modified radical mastectomy in 44 patients. Forty-five cases got follow-up for 1-22 years,33 cases had existed 3 years,18 cases had existed 5 years,8 cases had existed 10 years. Conclusions For axillary mass which causes are uncertain ,the possibility of OBC should be considered .Meanwhile excision and pathological examination is necessary.The metastatic histological structure and immunohistochemical index of the axillary nodes usually provide important clue for the source of this tumor.Radical or modified mastectomy is the best method, and pest-operative chemotherapy and/or radiotherapy should be done. It has been showed that targeted therapy is very important to breast cancer with C-erbB-2 positive recently.To the cases that neck lymphatic metastasis is M4G3 positive by immunohistochemical examination and no primary focus clinically, the diagnosis of OBC should be considered. The cases without primary focus have better prognosis than those with primary focus.

Objecfive To explore pathological mechanism and treatment of central hyponatrem-ia. Methods Synchronous assay was made to detect changes of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),endogenous digitalis-like substance(EDLS),antideuretic hormone (ADH),Na+ concentrations in blood and urine as well as osmotic pressure of plasma and urine in 68 pa-tients with traumatic brain injury(TBI). Results Of all,there were 27 patients with hyponatremia,mostly in patients with severe or critical TBI.There found syndrome of inappropriate secretion of antidi-uretic hormone(SIADH)in 7 patients and cerebral salt wasting syndrome(CSWS)in 20. Conclu-sions The central hyponatremia in patients with TBI may be related to the increased secretion of EDLS and ADH.The decrease of ANP and BNP in blood has no direct effect on Na+ concentration in blood.In-travenous injection of extrinsic thyrotropin releasing hormone(TRH)may inhibit dilutional hyponatremia resulted from increased secretion of ADH in TBI patients.

Diet survey in this country has indicated that the adequacy of the supply of vitamin B is mainly determined by the quantity of this vitamin presence in the staple food consumed. Analysis of milled kaoliang grain obtained in the market shows a much lower than adequate content of the vitamin. In a previous report, it has been shown that the distribution of various nutrients in this grain is similar to those in other cereals. It is apparent that the study of the effect of the milling process on the nutritive value of kaoliang is of considerable importance both to the improvement of human nutrition and to the conservation of this staple cereal.Experiment was made by running a quantity of red kaoliang sample eight times through a standard commercial mill. Samples were withdrawn after each run for determining the amount of various parts of the grain retained and for the analysis of thiamin, riboflavin, nicotinic acid, protein, fat, crude fibre and xylose. The weight of the whole grain removed was also estimated.More than 70％ of the pericarp was found to have been removed in the first run. When 20％ of the total weight was removed, the amount of pericarp left was negligible. This was in accordance with the loss of crude fibre and xylose which showed a greater rate of removal during the first few millings.With the increase of the degree of milling, the ateurone layer, the scutellum and the embryo were removed nearly at a similar rate. At the earlier stage of milling, the loss of thiamin was at a lower rate than that of nicotinic acid and riboflavin. After 15％ of the bran had been removed, its loss became more rapid and ran parallel with that of nicotinic acid, while the removal of riboflavin was at a comparatively lower rate. This can be satisfactorily explained by the uneven distribution of these vitamins in different parts of the grain.The percentage of fat removed at different stages of milling was about the same as that of riboflavin. High degree of milling also caused a lower content of protein in the grain.For better controlling the degree of milling and for reducing the friction in the milling process, a laboratory mill was used in a second experiment. The results obtained were nearly similar to those stated above with the exception of a better retention of scutellum during the early stage of milling.It is suggested that 80％ extraction is likely to be the most rational degree of milling. Owing to the differences between varieties, this may be varied accordingly.It seems that the content of xylose may be used as an index for the degree oi milling.
