Methods Six hundred and forty?three cases patients who underwent radical gastrectomy for gastric cancer from January 2010 to June 2015 in the NO. 309 Hospital of Chinese People’ s Liberation Army were selected and divided into Postoperative Pancreatic Fistula( POPF) group with 53 cases and Non?Postoperative Pancreatic Fis?tula( NPOPF) group with 590 cases. Preoperative,intraoperative and postoperative data were analyzed by statisti?cal analysis of two groups. Results POPF rate was 8. 24%(53/643). There were no significanct differences in terms of gender,age,preoperation with disease,preoperative serum albumin,TNM stage,abdominal surgery,sur?gical procedure,lymph node dissection,digestive tract reconstruction,surgical approach,blood loss and length of time between the POPF group and NPOP group(P>0. 05). The level of BMI of POPF group was higher than that of NPOPF group,the difference was statistically significant((25. 63±2. 54) kg/m2 vs. (21. 11±2. 44) kg/m2,t=2. 245,P=0. 025). The number of lymph node dissection in POPF group was (32. 25±5. 82),in NPOPF group was (27. 06±6. 79),there was significant difference between the two groups(t=2. 093,P=0. 037). The operation time in POPF group was (242. 50±52. 30) min,in NPOPF group was (229. 51±59. 21) min,the difference was statistically significant between the two groups( t=2. 398,P=0. 017) . The serum CRP of 1 d in POPF group was (85. 72±12. 05) mg/L,in NPOPF group was (76. 41±12. 52) mg/L,and there was significant difference between the two groups( t=1. 979,P=0. 048) . The serum albumin of 2?4 d after operation in POPF group was (26. 0±5. 9) g/L,in NPOPF group was (32. 6±6. 8) g/L,the difference between the two groups was statistically significant(t=-10. 185,P=0. 000). The drainage fluid amylase of 1 and 2 d after operation in POPF group was (2094+1444) U/L,in NPOPF group was (746+486) U/L,and there was significant difference be?tween the two groups( t=10. 400,P=0. 000) . Logistic regression analysis results showed that body mass index ( BMI) ,lymph node dissection number,time of operation,postoperative 1,2 d drainage fluid amylase and serum albumin of 2?4 d after operation were postoperative occurred pancreatic fistula risk factors( OR=1. 972,183. 6, 2. 004,0. 150,9. 809,P>0. 05). Conclusion BMI,number of dissected lymph node,duration of surgery,serum albumin of 2?4 d after operation and postoperative 1,2 d drainage fluid amylase have important clinical values for predicted POPF.

In ancient times, the original plants of Citri Exocarpium Rubrum and Citri Grandis Exocarpium had experienced succession and change, including tangerine(Citrus reticulata), pomelo(C. grandis), and Huazhou pomelo(C. grandis 'Tomentosa'), a specific cultivar of C. grandis produced in Huazhou, Guangdong. Before the Qing Dynasty, tangerine was the main original plant, while Huazhou pomelo came to the fore in the Qing Dynasty. In the 1950 s and 1960 s, the producing area of Huazhou pomelo was destroyed, and thus it had to be supplemented with pomelo. From then on, C. grandis 'Tomentosa' and C. grandis were both listed as the original plants of Citri Grandis Exocarpium in the Chinese Pharmacopoeia. This paper reviewed the historical evolution of the collection, processing, and efficacy of Citri Exocarpium Rubrum and Citri Grandis Exocarpium. The research showed that:(1)The harvest time of the original plants of Citri Grandis Exocarpium and Citri Grandis Exocarpium had changed from maturity to immaturity. The collection and processing of Citri Exocarpium Rubrum was first recorded in the Illustrated Classics of Materia Medica in the Song Dynasty. During the Ming and Qing Dynasties, the mesocarp of Citri Exocarpium Rubrum needed to be removed completely, and Citri Grandis Exocarpium from C. grandis 'Tomentosa' was processed into different specifications such as seven-piece, five-piece, and single piece. Furthermore, processed young fruits of Huazhou pomelo appeared.(2)Citri Exocarpium Rubrum and Citri Grandis Exocarpium were processed with carp skin for the first time in the Master Lei's Discourse on Medicinal Processing. It was suggested that carp skin might be helpful for eliminating bones stuck in throat. During the Song, Jin, and Yuan Dynasties, some other processing methods such as ba-king, stir-frying, and salt-processing appeared. Honey, soil, ginger juice, and alum were firstly used as adjuvants for the processing in the Ming and Qing Dynasties. Citri Exocarpium Rubrum was mainly prepared with salt in order to improve the effect of lowering Qi, while it was unnecessary for Citri Grandis Exocarpium from C. grandis 'Tomentosa' because of its obvious effect of lowering Qi and eliminating phlegm. The stir-frying and honey-frying methods helped reduce the strong effect of Citri Grandis Exocarpium from C. grandis 'Tomentosa'.(3)According to the application of Citri Exocarpium Rubrum and Citri Grandis Exocarpium in history, their medicinal use began in Han and Tang Dynasties, developed in Song, Jin, and Yuan Dynasties, and matured in Ming and Qing Dynasties. Citri Grandis Exocarpium from C. grandis 'Tomentosa' was originally applied in Ming and Qing Dynasties, and it still plays an important in role treating COVID-19 nowadays. Moreover, Citri Grandis Exocarpium from C. grandis had cold medicinal property, while Citri Grandis Exocarpium from C. grandis 'Tomentosa' had warm medicinal property, and thus they should not be treated the same. At present, Huazhou pomelo has a certain production scale. Therefore, it is recommended that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Citri Grandis Exocarpium, and C. grandis should be deleted. The results are conducive to the further development and utilization of Citri Exocarpium Rubrum and Citri Grandis Exocarpium, and support the rational use of Citri Grandis Exocarpium and its processed products.

ObjectiveTo investigate the effect of modified Taohe Chengqitang on NOD-like receptor protein 3 （NLRP3） inflammasome activation in rats with diabetic cardiomyopathy. MethodSPF male SD rats aged 3-4 weeks were randomly divided into a normal group and an experimental group. The rats in the experimental group were fed on a high-fat diet for 4 weeks and then received intraperitoneal injection of streptozotocin （STZ） at 35 mg·kg^-1 to induce the diabetes model. The rats in the experimental group were randomly divided into model group， low- and high-dose modified Taohe Chengqitang groups （11.7 g·kg^-1 and 23.4 g·kg^-1）， and metformin hydrochloride group （67.5 mg·kg^-1） according to the fast blood glucose （FBG）. The cardiac function and structure of rats were detected by ultrasonic imaging after 8 weeks of continuous intragastric administration. Blood samples from the femoral artery were collected to detect FBG， triglyceride （TC）， and total cholesterol （TG） of rats. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in rat myocardium. Serum levels of interleukin-1β （IL-1β） and interleukin-18 （IL-18） were determined by enzyme-linked immunosorbent assay （ELISA）. The protein expression of NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， cysteinyl aspartate-specific protease 1 （Caspase-1）， and phosphorylated nuclear factor kappa-B p65 （p-NF-κB p65） in the myocardium was detected by Western blot. ResultCompared with the normal group， the model group showed increased levels of FBG， TC， and TG （P<0.01）， decreased left ventricular ejection fraction （EF） and left ventricular fractional shortening （FS） （P<0.05）， myocardial hypertrophy and myocardial fibrosis as revealed by HE staining， increased serum levels of 1L-1β and 1L-18 and protein expression of NLRP3， ASC， Caspase-1， and p-NF-κB p65 in myocardial tissues （P<0.01）. Compared with the model group， the modified Taohe Chengqitang groups and the metformin group showed reduced levels of FBG， TC， and TG （P<0.05）， restored EF and FS （P<0.05）， improved pathological changes in myocardial tissues， and decreased serum levels of IL-1β and IL-18 and protein expression of NLRP3， ASC， Caspase-1， and p-NF-κB p65 in myocardial tissues （P<0.05）. The improvement was more significant in the high-dose modified Taohe Chengqitang group （P<0.05）. ConclusionModified Taohe Chengqitang can protect the myocardium by inhibiting the activation of NLRP3 inflammasomes.

In ancient times, there were two types of "Juhong" came from the tangerines(Citrus reticulata) and the pomelos(C. grandis and its cultivars), which corresponded to Juhong and Huajuhong recorded in the Chinese Pharmacopoeia respectively. In different periods, Juhong basically came from the same species and the same medicinal parts, but there were also some differences. This article sorted out the ancient and modern literature, under the guidance of "Succession theory of Medicinal materials varieties" and "Change theory of Medicinal materials varieties"(XIE Zong-wan), and combined with field investigation, the evolution and reasons of the original plants and medicinal parts of Juhong were analyzed. In the Han Dynasty and before, the peel of tangerines and pomelos were both used as medicine. In the Southern and Northern Dynasties, the way tangerine peel was used was dried and aged, and then "soaked in hot water and scraped off the mesocarp", which had the essence of only using exocarp as medicine of Juhong already, and its original plant was C. reticalata. In the Song Dynasty, the name of "Juhong" and its medicinal usage were recorded in book on materia medica, and the species and medicinal parts of tangerine were inherited from the previous dynasties. The way tangerine peel was used was only dried and aged without removing the mesocarp. The medicinal material obtained by the way was called Chenpi(dried and aged tangerine peel). The item "Juhong" listing as a separate medicinal material was first recorded in the Collected Discussions from Materia Medica(Bencao Huiyan) in the Ming Dynasty. In the Ming Dynasty, the Dao-di habitat of Juhong was recorded as Guangdong province in most books on materia medica, and the original plants probably were C. reticalata and C. grandis 'Tomentosa'(Huazhou pomelo, a special cultivated species of C. grandis produced in Huazhou, Guangdong, which was recorded in the Chinese Pharmacopoeia as "Huajuhong"), according to the records in the local chronicles. During the Qing Dynasty and the Republic of China, the original plants of Juhong were C. reticalata and C. grandis 'Tomentosa'. Of the two, the latter one was considered as the better. As far the medicinal part, it was still the exocarp, while the whole young fruit of C. grandis 'Tomentosa' began to be used as medicine. After the founding of The People's Republic of China, the exocarps of Citrus reticalata, C. grandis and C. grandis 'Tomentosa' were listed in the Chinese Pharmacopoeia under "Juhong". From the Northern and Southern Dynasties to the Republic of China, C. grandis exocarp was a fake of Juhong. Therefore, it was contradictory to historical records that C. grandis exocarp was listed in the Chinese Pharmacopoeia as Huajuhong. Juhong had been divided into two types as "Juhong" and "Huajuhong" since 1985. The medicinal part of Huajuhong was only the exocarp of immature and nearly mature fruits, but not the whole young fruit, the actual mainstream medicinal part of Huajuhong. The results are helpful to clarify the historical evolution of species and medicinal parts of Juhong and Huajuhong. It is suggested that in the next edition of Chinese Pharmacopoeia, only C. grandis 'Tomentosa' should be included as the original plant of Huajuhong, and C. grandis should be deleted, and the young fruit should be added in the medicinal parts besides the exocarp of immature and nearly mature fruit.
