ABSTRACT
Since the beginning of this century, three types of coronavirus have widely transmitted and caused severe diseases and deaths, which strongly indicates that severe infectious diseases caused by coronavirus infection are not accidental events. Coronavirus-infected diseases are mainly manifested by respiratory symptoms, with multiple organ dysfunctions. Precisely investigating the pathological process, characteristics and pathogenesis of coronavirus-infected diseases will be beneficial for us to understand clinical manifestations and provide targeted suggestions on prophylaxis and treatment. This paper briefly reviews the pathological findings of three known coronavirus-infected diseases, and attempts to construct the pathological spectrum of coronavirus-infected diseases, aiming to provide reference and thinking for autopsy, histopathological examination and animal infection model study of coronavirus-infected diseases.

Objective To study the correlation between the abdominal wall subcutaneous fat thickness and heart weight, so as to provide reference for prediction methods of normal range of heart weight that is suitable for autopsy in China. Methods The forensic pathology autopsy cases accepted by Center for Medicolegal Expertise of Sun Yat-sen University from 1998 to 2017 were collected. Then the exclusion criteria were determined, and according to them the total case group was selected, and the 6 disease groups and the normal group were further selected from the total case group. The rank sum test was used to compare the heart weight of the normal group and the disease groups to determine the influence of diseases on heart weight. Then the Spearman rank correlation analysis of abdominal wall subcutaneous fat thickness and heart weight in different genders and different ages in the total case group and the normal group was conducted to get the correlation coefficient （rs）. Results In the total case group, correlation between abdominal wall subcutaneous fat thickness and heart weight was shown in males of all ages （P<0.05）; while in females, the correlation had no statistical significance （P>0.05） in 15-<20 age and 50-<60 age, but was statistically significant （P<0.05） in other age groups. For the males in the normal group, rs was respectively 0.411, 0.541 and 0.683 in the 15-<40 age, the 40-<60 age, and the ≥60 age. For the females, rs was respectively 0.249 and 0.317 in the 15-<40 age and the 40-<60 age. The correlation in the ≥60 age had no statistical significance（P>0.05）. Conclusion In the general population and the normal population, abdominal wall subcutaneous fat thickness is correlated with the heart weight of males. It is of significance to include the abdominal wall subcutaneous fat thickness in the prediction of normal range of heart weight for males in China.

The National Medical Products Administration intends to simplify the registration and approval process of the classic Chinese herbal compound preparations that meet the requirements, but it is a prerequisite for obtaining preferential policies that the preparation method and the route of administration are consistent with the records of ancient medical books. As most of the famous classical formulas are recorded in the medical books of the Qing dynasty and before the Qing dynasty, during the use of medicinal materials in various dynasties, the processing of herbs, dose of medicinal herbs, and the method of decocting may have changed. If researchers simply adopt modern methods to study the formula, it is easy to deviate from policy requirements. The strengthening of preliminary data survey and definition of prescription component and the medication situation of the dynasties can provide strong theoretical support for the study of famous classical formulas. Based on this, the authors take Xiebaisan as an example, which being collected in the First Batch of Catalogue of Ancient Classical Formulas. By following the principles of ancient methods, the research and development ideas of the classic Chinese herbal compound preparations were expounded from the aspects of origin of medicinal materials, processing of medicinal materials, preparation of standard decoction and quality standard of Xiebaisan granules, so as to provide a referential method for the development and research of the famous classical formulas.
ABSTRACT
Objective To discuss the methods and strategies to identify the causes of dependents' deaths, as well as provide the experiences that can be used for reference and scientific basis for the forensic identification of the potentially growing deaths of the same kind in the future. Methods The 13 cases concerning death of dependents accepted by Sun Yat-sen University Forensic Center were collected, and the basic information of the dependents were statistically described. The nutritional status, environmental condition and medical care condition were evaluated according to dietary energy, living space, environment and medical treatment condition. Results Among the 13 dependents, there were 11 males and 2 females, with the oldest 74 and the youngest 9 and dwelling time was from 0.4 to 5.6 years. Forensic pathological examination showed that 13 dependents had infectious diseases and 11 were severely dystrophic. There were no fatal mechanical injuries or poisoning in dependents. Molecular pathological screening of 4 cases revealed no pathogenic variants of sudden death susceptible genes. The poor status of the diet, nutrition, living environment and medical care of these dependents were discovered. The direct cause of death of all 13 dependents was identified to be disease. The lack of nutrition, poor living environment and lack of medical care were thought to play a dominant role in causing the deaths of 12 dependants. Conclusion The death identification should follow the judicial procedure. In identification of the causes of death and analysis of the proportion of the affecting factors resulting in death, all factors, including nutrition,environment, medical care, injury and diseases, need to be considered.

Ultrafiltration is one of the most fascinating technologies, which makes it possible to improve the quality of traditional medicines for application in the pharmaceutical industry. However, researchers have paid little attention to the effect of ultrafiltration membrane on traditional medicines chemical constituents. In this work, Ophiopogon japonicus (L.f) Ker-Gawl. was used as an example to illuminate the influence of ultrafiltration with different material and molecular weight cut-off (MWCO) membrane on natural chemical constituents as measured by ultra-fast liquid chromatography coupled with ion trap time-of-flight mass spectrometry (UFLC-IT-TOF/MS). Our results indicated that ultrafiltration membrane significantly impacted homoisoflavonoids, especially homoisoflavonoids that were almost completely retained on the polyethersulfone (PES) membrane. We also found that the larger number of aglycone hydroxy and sugar moiety in steroid saponins, the higher the transmittance. Furthermore, the passage rate (%) of ophiogenin type saponins was higher than that of others. The possible adsorptive mechanisms were hydrogen bonding, hydrophobic interactions, and benzene ring interaction by π-π stacking. In conclusion, it is crucial to choose appropriate ultrafiltration membrane based on the characteristics of produce products for application of ultrafiltration technique.

ABSTRACT
In present study, an ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS)-based plant metabolomics approach was established to investigate the metabolic profiles of the leaves, main root, branch root, and rhizome of Mountain Cultivated Ginseng (MCG). The UHPLC-QTOF/MS data were subjected to principal component analysis (PCA) and orthogonal partial least squared discrimination analysis (OPLS-DA) to find the potential characteristic components of the four parts of MCG in a quick way. The four different parts could be separated into four different groups of phytochemicals according to the PCA scores. The chemical constituents in four parts of MCG were obviously different. The identities of 81 major peaks that were detected in the four parts of MCG and the potential markers were identified by comparison with the reference compounds or were tentatively assigned by matching the retention time,empirical molecular formula and fragment ions with those of the published compounds of the Panax species. This proposed analytical method is fast, accurate, and reliable for differentiating the different parts of MCG. Moreover, this study supplied a new method for the quality evaluation of other Chinese medicinal materials.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Kanli Granule (KG) on myocardial mechanics in pressure overload induced diastolic heart failure (DHF) rats.</p><p><b>METHODS</b>Totally 60 male Wistar rats were divided into the sham-operation group, the model group, the KG group, and the Valsartan group according to random digit table, 15 in each group. The pressure overload induced DHF model was established in all groups except the sham-operation group using abdominal aortic constriction surgery. Totally 7 rats died after modeling (with the mortality of 10. 67%) , and the rest 53 finished the following test. Rats in the KG group were administered with KG extract (calculated as 6. 75 g crude drug/kg) by gastrogavage. Rats in the Valsartan group were administered with Valsartan (7.2 µg/g) by gastrogavage. Equal volume of double distilled water was administered to rats in the model group and the sham-operation group by gastrogavage. All rats were intervened for 32 weeks. The response of isolated heart papillary muscle tonus to isoprenaline (ISO) and adenylate cyclase (Forskolin) was respectively observed. The enhancement phenomenon after resting development force (DF) of isolated heart papillary muscle tonus, and changes of DF in different Ca²⁺ concentrations were observed.</p><p><b>RESULTS</b>(1) In the ISO response test: Compared with the sham-operation group, the amplifications of DF, ±df/dt, -df/dt were obviously elevated in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously lowered in the KG group (P < 0.01), and the amplification of ±df/dt was also reduced in the Valsartan group (P < 0.01). (2) In the Forskolin response test: Compared with the sham-operation group, the amplifications of DF and ±df/dt obviously increased in the model group (P < 0.05). Compared with the model group, the amplifications of DF and ±df/dt were obviously reduced in the KG group (P < 0.01), and the amplification of DF was also reduced in the Valsartan group (P < 0.05). (3) In post-resting DF enhancement test: Compared with the sham-operation group, the amplification of DF showed gradually decreasing tendency along with prolonged resting time in the model group, and they were obviously lowered at all time points (P < 0.05). Compared with the model group, the amplification of DF was gradually increasing along with prolonged resting time in the KG group. The amplification of DF at post-resting 240 s was obviously larger in the KG group than in the model group (P < 0.05). The amplification of post-resting DF still showed gradually decreasing tendency along with prolonged resting time in the Valsartan group, with increased amplifications of DF at post-resting 60 s and 120 s (P < 0. 05) (4) The amplifications of DF in different Ca²⁺ concentrations: Compared with the sham-operation group, the amplifications of DF were significantly elevated in different Ca²⁺ concentrations (1.75, 3.5, 7.0 mmol/L ) (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in amplification of DF in different Ca²⁺ concentrations in the KG group (P > 0.05). The amplifications of DF in different Ca²⁺ concentrations were significantly reduced in the Valsartan group (P < 0.05).</p><p><b>CONCLUSIONS</b>The ISO response and the Forskolin response were enhanced in isolated heart papillary muscle tonus of pressure overload induced DHF rats; enhanced post-resting DF was reduced; DF in different supra-physiologic levels of Ca²⁺ was still enhanced. KG could significantly improve excessive enhancement of pressure overload induced DHF rats in ISO response and Forskolin response, and improve enhancement of post-resting myocardium.</p>

Xin-Sheng-Hua granule (XSHG) is a popular remedy commonly used in clinic for the treatment of lochiostasis after delivery. To comparatively investigate the roles of herb pairs containing Angelicae Sinensis Radix (Danggui) upon the formula by evaluating the blood coagulation and hemorheology function in acute blood stasis rats, acute blood stasis rat model was established by ice water bath and subcutaneous injection of adrenaline. And the blood stasis mice were administrated intragastrically with different samples of the formula minus herb pairs containing Danggui and the whole formula (XSHG, SHD, DY, DC, DT, DH, DJ and DZ). The whole blood viscosity (WBV), plasma viscosity (PV), erythrocyte sedimentation rate (ESR) and haematocrit (HCT) were applied to evaluate the effects of the formula minus herb pairs containing Danggui on hemorheology of blood stasis rats. The thrombin time (TT), activated partial thromboplastin time (APTT), prothrombin time (PT), and plasma fibrinogen (FIB) were used to observe the effects of the formula minus herb pairs containing Danggui on blood coagulation function of blood stasis rats. Additionally, the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of different samples on platelet aggregation index of blood stasis rats.Afterwards, multi-attribute comprehensive index methods and principal component analysis were both applied to comprehensively assess the total effects of the formula minus herb pairs containing Danggui on promoting blood circulation and dissipating blood stasis. Compared with normal group, the hemorheological parameters and coagulation indexes of model group had statistical differences (P<0.01). Compared with model group, different samples (XSHG, SHD, DY, DC, DT, DH, DJ and DZ) could improve the blood hemorheology indexes, coagulation parameters and platelet aggregation in acute blood stasis rats. According to multi-attribute comprehensive index methods and the principal component analysis, the effects of promoting blood circulation by removing blood stasis became poor when excluding herb pairs containing Danggui from the formula, the sample DY and DC had the weakest effect of activating blood circulation and dissipating blood stasis, and the effect of sample DY was slightly poorer than DC. The orders of contribution of herb pairs containing Danggui on the formula were Danggui-Yimucao>Danggui-Chuanxiong>Danggui-Honghua>Danggui-Zhigancao>Danggui-Taoren>Danggui-Jiangtan. In conclusion, various herb pairs containing Danggui played different roles on the effects of improving the abnormality of hemorheology and coagulation function. And the herb pairs Danggui-Yimucao were particularly important for the formula, which was consistent with the characteristics of XSHG and the traditional effect of Yimucao. Moreover, it could lay foundation to further reveal the compatibility mechanism of XSHG.
ABSTRACT
Growth year is one of the important factors for the quality of mountain cultivated ginseng (MCG). For age differentiation of MCG, rhizome extracts of ginseng aged from 11 to 15 years were analyzed using a non-targeted approach with ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS)-based on plant metabolomics technique. Multivariate statistical methods such as principal component analysis (PCA) and orthogonal partial least squared discrimination analysis (OPLS-DA) were used to compare the derived patterns among the samples. The results showed that the chemical constituents of MCG rhizome extracts of ginseng aged from 11 to 15 years were different. The data set was subsequently applied to metabolite selection by variable importance in the projection (VIP) for sophisticated classification with the optimal number of metabolites. The OPLS-DA model of MCG has a high interpretability and predictive capability, which established by selecting metabolites of MCG aged from 11 to 15 years. By this approach, MCG samples aged from 11 to 15 years, which are the most in demand in the Chinese ginseng market, can be precisely differentiated on the basis of selected metabolites. This proposed analytical method is fast, accurate, and reliable for discriminating the growth year of MCG. Moreover, this study supplies a new method for the age discrimination of other Chinese medicinal materials.
