ABSTRACT
By consulting ancient materia medica， medical books， prescription books and modern literature， this paper systematically combed and reviewed the name， origin， scientific name evolution， producting area， quality evaluation， medicinal parts， harvesting and processing and traditional efficacy of Lasiosphaera Calvatia. The results show that Mabo was first recorded in Mingyi Bielu. Since then， all dynasties have taken Mabo as a legitimate name. Before the Song dynasty， only Calvatia lilacina was used as the original plant of Lasiosphaera Calvatia， which was expanded after the Song dynasty with the appearance of C. gigantea， Lasiosphaera fenzlii， Bovistella radicata and other varieties. Until modern times， there was an addition of Lycoperdon perlatum， L. pyriforme and other original plants of Lasiosphaera Calvatia. Since 1975， the original plant of Lasiosphaera Calvatia in various regulations and academic monographs has been basically uniform for C. lilacina， Lasiosphaera fenzlii and C. gigantea. Resource of the medicinal fungus was widely distributed in China and was mainly wild. From ancient times to the present， the medicinal parts of Lasiosphaera Calvatia are all fruiting body， which is harvested in summer and autumn， and its processing method was to take powder in ancient times， but to cut blocks in modern times. In recent times， its quality has been summarized as large， thin-skinned， intact， full， loose-bubbled and elastic. The medicinal efficacy has been developed from very good for all scores， and after the Ming and Qing dynasties， it is consistent with the 2020 edition of Chinese Pharmacopoeia， with the efficacy of clearing the lung， promoting pharynx， relieving fever and hemostasis， mainly treating cough aphonia， throat obstruction and pharyngeal pain， vomiting blood， epistaxis， hemoptysis， and external treating sores and bleeding from cuts and wounds. Based on the results of herbal textual research， it is suggested that C. lilacina is the first choice for the origin of Lasiosphaera Calvatia involved in famous classical formulas， and it is processed into block or powder for medicine.
ABSTRACT
This article has systematically sorted out and verified the name， origin， producing area， quality evaluation， harvesting and processing of Pruni Semen by consulting ancient materia medica， medical books， prescription books and modern literature， in order to provide a basis for the development of famous classical formulas containing Pruni Semen. The results showed that Pruni Semen， as a medicinal material， has been widely used in medical literature of past dynasties since it was collected in Shennong Bencaojing， and also included under the names such as Yuhe， Yuzi and Yuli， and aliases such as Jueli， Queli and Chexiali. The primordial plants mentioned in the past dynasties involve about 12 species of Rosaceae， but with Prunus humilis， P. japonica and P. glandulosa as mainstream varieties used in the past dynasties， while the 2020 edition of Chinese Pharmacopoeia stipulates that the basal plants are P. humilis， P. japonica and P. pedunculata. Most of the ancient records for the origin of Pruni Semen are found everywhere in high mountains， valleys and hills， modern literature records that its origin varies according to its base， for example， P. humilis and P. japonica are mainly produced in Hebei， eastern Inner Mongolia， Liaoning， Shandong and other regions of China， and P. pedunculata is mainly produced in Inner Mongolia. Modern literature summarizes its quality as faint yellow， full and fulfilling， neat and not broken， and non-oiling， and the small Pruni Semen is better than the big Pruni Semen. The ancient processing methods of Pruni Semen mainly include blanching and peeling， blanching and peeling followed by frying， and blanching and peeling followed by pounding， with the common feature of blanching and peeling. The successive editions of Chinese Pharmacopoeia stipulate that it should be pounded when used. Based on the results of the herbal textual research and the writing time of Bianzhenglu， and combined with the market survey of Pruni Semen， it is suggested that P. humilis or P. japonica should be used as the origin of Pruni Semen in Sanpiantang， and it is harvested when the fruits are ripe， the kernels are collected by removing the stones， and processed by blanching， peeling and pounding consulting the decoction method in the current edition of Chinese Pharmacopoeia.
ABSTRACT
Objective To investigate the relationship between DNA topoisomerase Ⅱ α (TOP2A) gene expression and clinicopathological characteristics and its significance of prognostic evaluation for patients with bladder cancer.Methods Bladder cancer gene expression profile GSE13507 (n =165) and GSE31189 (n =52) were obtained.The expression profile and clinical information of patients with bladder cancer were retrospectively analyzed,and the survival analysis was made.Gene set enrichment analysis (GSEA) was conducted to explore the related pathways which were regulated by TOP2A.Results Compared with normal bladder tissues,TOP2A was upregnlated in bladder cancer tissues (5.823 ± 1.079 vs.4.820 ± 1.129),with a statistically significant difference (t =4.336,P ＜ 0.001).The TOP2A gene expression in patients with bladder cancer was correlated with the age of patients (x2 =5.926,P =0.015),sex (x2 =6.046,P =0.014),T staging (x2 =19.484,P ＜ 0.001),N staging (x2 =9.178,P =0.002),M staging (x2 =21.142,P ＜ 0.001),tumor grade (x2 =47.005,P ＜ 0.001),and progression (x2 =11.735,P =0.001),but it was not correlated with recurrence (x2 =0.808,P =0.369).Survival analysis showed that the specific survival rate in the 100 months of TOP2A gene high expression group and low expression group had a statistically significant difference (66.59％ vs.87.95％,x2 =15.820,P ＜ 0.001).The median overall survival time of TOP2A gene high expression group and low expression group were 51.77 months and 134.97 months respectively,with a statistically significant difference (x2 =11.280,P =0.008).The results of GSEA indicated that TOP2A could regulate gene sets related with several pathways like MYC-V1 signaling (P =0.035,FDR =0.132),MYC-V2 signaling (P =0.012,FDR =0.058),E2F signaling (P ＜ 0.001,FDR =0.006) and G2M checkpoint (P =0.006,FDR =0.044).Conclusion The TOP2A gene expression is closely related with clinicopathological characteristics of patients with bladder cancer.TOP2A may function as a potential marker of prognosis for patients with bladder cancer.
ABSTRACT
The wearable respiratory inductive plethysmograph(RIP) system is a non-intrusive respiratory monitoring system. Sleep monitoring was performed on 9 human subjects suspected of having sleep apnea hypersomnolence syndrome (SAHS) and 7 healthy volunteers using both the wearable RIP system and the conventional polysomnography(PSG), and the sensitivity and specificity of the wearable RIP system were analyzed by comparison with the PSG results. According to the characteristic of the wearable RIP system in detecting sleep apnea/hypopnea event, the diagnostic criteria of sleep apnea/hypopnea event were put forward. All subjects with SAHS diagnosed by the wearable RIP were confirmed by PSG,the sensitivity and specificity of the wearable RIP system for detecting sleep apnea/hypopnea events were 99.0% and 94.6% respectively. The wearable RIP system can be used reliably in detecting sleep apnea/hypopnea events. This system can be used at home for detecting the sleep apnea/hypopnea events non-intrusively.

Objective To extract breathing pattern parameters during sleep and get the varying law of NREM and REM sleep stages. Method A newly designed respiratory inductive plethysmography (RIP) and a polysomnography (PSG) are utilized to record whole-night-sleep data simultaneously. The breathing pattern parameters obtained by RIP are dealt with according to the results of sleep stages and sleep apnea by PSG. Then the rule found out and summarized from the experiment is applied to distinguish REM sleep. Conclusion RC/VT can be used as an effective parameter to differentiate NREM and REM sleep. Using this parameter, the results of RIP totally accord with the results of PSG.
