ABSTRACT
ObjectiveTo analyze the functions， formulae， dosage forms， and methods of administration of the menstruation-regulating Chinese patent medicines included in the 2020 edition of the Chinese Pharmacopoeia， so as to provide reference for rational clinical use. MethodThe relevant Chinese patent medicines were recorded one by one， and the efficacy， dosage forms， methods of administration， and contraindications were counted， classified， and summarized. Further， we analyzed the Chinese medicines used in these Chinese patent medicines， identified the high-frequency Chinese medicines for menstrual regulation， and analyzed their natures， tastes， meridian tropism， and functions， aiming to guide the clinical use. ResultA total of 142 Chinese patient medicines for menstrual disorders were included in this study. They were classified into 12 categories according to their efficacy， mainly for regulating menstruation and blood， tonifying， activating blood， and eliminating mass. The representative Chinese patent medicines were Bazhen Yimu pills， Shaofu Zhuyu pills， Lyujiao Buxue granules， and Guizhi Fuling pills， which are in line with the principles of moving Qi and blood and regulating liver and spleen. Menstruation-regulating Chinese patents medicines are mostly in pills and capsules and are mainly taken with yellow wine or ginger decoction. Pregnancy was the contraindication with the highest frequency， followed by menstruation and dietary precautions. The high-frequency Chinese medicines mainly had the functions of tonifying， activating blood， resolving stasis， and clearing heat， with the top three being Angelicae Sinensis Radix， Paeoniae Radix Alba， and Chuanxiong Rhizoma. These medicines mainly had warm nature， sweet， bitter， and pungent tastes， and tropism to liver and spleen meridians. ConclusionThe treatment of menstrual disorders should focus on nourishing and activating blood， regulating Qi， tonifying kidney， supporting spleen， nourishing liver， and harmonizing stomach. The appropriate dosage form should be selected according to the patient's specific conditions. The medicinal guide and the method of administration should be selected on the basis of syndrome differentiation with attention to the contraindications. In summary， the Chinese patient medicines for menstrual regulation should be chosen based on the patient’s syndrome under guidance of the theory of traditional Chinese medicine.
ABSTRACT
Objective:To investigate the predictive effect of perioperative depression and anxiety symptoms in breast cancer patients on the fear of cancer recurrence.Methods:A total of 194 patients with breast cancer during perioperative period from May 2019 to May 2020 in Qilu Hospital of Shandong University were selected. The depression, anxiety and fear of cancer recurrence were investigated by the general information questionnaire, the Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9) and the Fear of Progression Questionnaire-Short Form (FOR-Q-SF) at admission and two weeks after surgery, respectively.Results:Perioperative depression and anxiety symptoms of breast cancer patients were significant predictors of fear of cancer recurrence ( B value was 2.325, OR value was 10.22, P<0.05; B value was 2.570, OR value was 13.07, P<0.05), and patients with depression and anxiety symptoms after surgery were at higher risk of fear of cancer recurrence ( OR values were 7.653-25.403, P<0.01). Conclusions:For breast cancer patients with negative emotions and fear of disease progression, it is necessary to help them improve their psychological coping ability, encouraging patients to actively cooperate with follow-up treatment, improving the prognosis, and improving their overall quality of life.
ABSTRACT
Malignant tumors still threatens the human's health seriously. Metastasis and recurrence lead to the failure of treatment, and multidrug resistance adds the difficulty of therapy of to malignant tumors. But the mechanism is yet unclear. Nowadays, it is found that there's a small group of cells with selfrenewal and indefinite potency in the tumors, and they are the sources of metastasis and recurrence. This small group of cells is called cancer stem cells. Subsequently, the cancer stem ceils were separated and determined from hematological system tumor and solid tumor respectively. The cognitions for metastasis and recurrence and muhidrug resistance of malignant tumor have changed with proposal and verification of the cancer stem cell theory, which provides a new clue to the treatment of tumor and prevention for the metastasis and recurrence.
ABSTRACT
Objective:To clone and express the gene of ovomucoid,which is the main allevgen in egg white.Methods:Using total RNA of chicken oviduct as template,the gene of ovomucoid was amplified by RT-PCR.The homology was analyzed by comparision with the sequence in GeneBank.Subsequently,the PCR product of the ovomucoid gene was cloned into prokaryotic expressing vector pET-28a and was expressed by the challenge of IPTG.Results:The whole gene of ovomucoid,one of the main allergens in egg white,was successfully cloned.The cloned ORF sequence contains 633 bp,including stop codon,encods for 210 amino acids.Sequence analysis shows that the ovomucoid gene displays 99% nucleotide identities with the published sequences.The molecule weight of ovomucoid protein obtained was 21 kD.By the challenge of IPTG,SDS-PAGE analysis showed that the ovomucoid gene was overexpressed in E.coli BL21(DE3).Conclusion:The gene of ovomucoid is cloned and overexpressed in E.coli BL21(DE3).This study will be the basis for the further research.
