[Efficacy of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy for pseudomyxoma peritonei].

Objective: To evaluate the efficacy and safety of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of pseudomyxoma peritonei (PMP). Methods: In this descriptive case series study, we retrospective analyzed the records of PMP patients treated with CRS and HIPEC between January 2013 and June 2023 at Affiliated Cancer Hospital and Institute of Guangzhou Medical University. The inclusion criteria were as follows: (1) Aged 18 to 75 years and nonpregnant women. (2) Histologically confirmed diagnosis of pseudomyxoma peritonei. (3) Karnofsky Performance Scale (KPS)>70. (4) The functions of major organs such as the heart, liver, lungs, and kidneys can tolerate major surgery for long periods of time. (5) No evidence of extra-abdominal metastasis. Patients with extensive intra-abdominal adhesions or severe infectious diseases were excluded. The main outcomes were overall survival (OS) and postoperative major complications. The postoperative major complications were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 5.0). We used the peritoneal cancer index (PCI) score to quantitatively assess the peritoneal metastases and the completeness of cytoreduction (CCR) score at the end of surgery (CCR-0 and CCR-1 considered to be complete CRS). Results: A total of the 186 PMP patients with a median age of 56 (interquartile range extremes (IQRE), 48-64) years were included, 65 (34.9%) males and 121 (65.1%) females. The median peritoneal cancer index (PCI) score was 28 (20-34). Appendiceal origin accounted for 91.4%. Histological types were low grade in 99 patients (53.2%), high grade in 57 patients (30.6%), and 55 patients (29.6%) received complete cytoreduction (CCR-0/1). The median operative duration was 300 (211-430) minutes for all patients. Treatment-related 30-day mortality was 2.7%; 90-day mortality 4.3%; reoperation 1.6%; and severe morbidity 43.0%. Within the entire series, anemia(27.4%), electrolyte disturbance(11.6%), and hypoalbuminemia(7.5%) were the most frequent major complications (grade 3-4). The incidences of gastrointestinal anastomotic leakage, abdominal bleeding, and abdominal infection were 2.2%, 2.2%, and 4.3%, respectively. After a median follow-up of 38.1 (95%CI:31.2-45.1) months, the 5-year OS was 50.3% (95%CI: 40.7%-59.9%) with a median survival time of 66.1 (95%CI: 43.1-89.1) months. The survival analysis showed that patients with pathological low grade, low PCI, and low CCR score had better survival with statistically significant differences (all P<0.05). Further stratified into complete and incomplete CRS subgroups, the 5-year OS of the CCR-0 and CCR-1 subgroups was 88.9% (95%CI: 68.3%-100.0%) and 77.6% (95%CI: 62.7%-92.5%), respectively; and 42.0% (95%CI: 29.5%-54.5%) in the CCR-2/3 subgroup. Conclusions: CRS and HIPEC may result in a long-term survival benefit for PMP patients with acceptable perioperative morbidity and mortality. This strategy, when complete CRS is possible, could significantly prolong survival for strictly selected patients at experienced centers.

A prospective multicentre controlled study of Gaoweikang (Chinese multiherb extract-based tincture) used in high-risk HPV infections.

OBJECTIVE: The aim of the study was to investigate the safety and antiviral efficacy of a Chinese multiherb extract-based tincture (GWK) on a population of patients with high-risk human papilloma (hrHPV) infections and hrHPV-caused cervical low-grade squamous intraepithelial lesions (LSILs). PATIENTS AND METHODS: Patients with persistent hrHPV infection were enrolled in Group A, including A1 subjects, who received the intervention, and A2 subjects, who received the control. Patients with hrHPV infection causing cervical LSIL were enrolled in Group B, which included B1 subjects, who received the intervention, and B2 subjects, who served as the control. For Groups A1 and B1, hrHPV was tested at 3 months (M3) and 6 months (M6) after the intervention. The side effects were also analyzed. RESULTS: At baseline (D0), a total of 99 patients were enrolled in Group A, with 50 subjects in Group A1 and 49 subjects in Group A2. A total of 91 patients were enrolled in Group B, with 45 subjects in Group B1 and 46 subjects in Group B2. There was no significant difference in the characteristics, including average age, age stratification, and HPV genotype. At M6, both Group A1 and Group B1 had a higher hrHPV clearance rate than the control group (A1/A2: 80.0% vs. 20.4%; B1/B2: 64.4% vs. 15.2%, p<0.001). At M6, the effective rates of Group A1 and Group B1 were 84% (42/50) and 68.9% (31/45), respectively. The side effect rates of Groups A1 and B1 were 11.5% (6/52) and 11.1% (5/45), respectively. Most adverse reactions involved local discomfort, including vulvar erythema, vulvar itch, increased vaginal discharge, cervical bleeding, and mild pain in the lower abdomen. Univariate logistic regression analysis showed that the intervention had an OR of 12 (95% CI 4.431-32.50) for clearing persistent HPV infection (p<0.001). For cervical LSIL, the intervention had an OR of 10.1 for clearing persistent HPV infection (95% CI 3.68-27.7) (p<0.001). CONCLUSIONS: The results of this study suggest that the Chinese multiherb extract-based tincture GWK is safe and well tolerated. Furthermore, this preliminary study showed that this Chinese multiherb extract-based tincture is helpful for promoting HPV clearance in cases of persistent HPV and HPV-induced LSIL.

[Spectrum-effect relationship of total anthraquinone extract of Cassia seeds against fluorouracil-induced liver injury in mice].

OBJECTIVE: To investigate the spectrum-effect relationship between the total anthraquinone extract of Cassia seeds and fluorouracil (5-Fu)-induced liver injury in mice and identify the effective components in the extract. METHODS: A mouse model of liver injury was established by intraperitoneal injection of 5-Fu, with bifendate as the positive control. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and myeloperoxidase (MPO), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) in the liver tissue were detected to investigate the effect of the total anthraquinone extract of Cassia seeds (0.4, 0.8 and 1.6 g/kg) on liver injury induced by 5-Fu. HPLC fingerprints of 10 batches of the total anthraquinone extracts were established to analyze the spectrum- effectiveness of the extract against 5- Fu- induced liver injury in mice and screen the effective components using the grey correlation method. RESULTS: The 5- Fu- treated mice showed significant differences in liver function parameters from the normal control mice (P < 0.05), suggesting successful modelling. Compared with those in the model group, serum ALT and AST activities were decreased, SOD and T- AOC activities significantly increased, and MPO level was significantly lowered in the mice treated with the total anthraquinone extract (all P < 0.05). HPLC fingerprints of the 31 components in the total anthraquinone extract of Cassia seeds showed good correlations with the potency index of 5-Fu-induced liver injury but with varying correlation strengths. The top 15 components with known correlations included aurantio-obtusina (peak 6), rhein (peak 11), emodin (peak 22), chrysophanol (peak 29) and physcion (peak 30). CONCLUSION: The effective components in the total anthraquinone extract of Cassia seeds, including aurantio-obtusina, rhein, emodin, chrysophanol, and physcion, are coordinated to produce protective effects against 5-Fu-induced liver injury in mice.

Passion fruit peel and its zymolyte enhance gut function in Sanhuang broilers by improving antioxidation and short-chain fatty acids and decreasing inflammatory cytokines.

The passion fruit peel (PFP) is the by-product of juice processing and is rich in phenolic compounds and dietary fibers. As the high ADF content in PFP (34.20%), we proceeded to treat PFP with cellulase. The ADF decreased to 16.70% after enzymatic processing, and we supposed that enzymolytic passion fruit peel (EPF) should have a greater growth performance than PFP to broilers. Two trials were conducted to evaluate the effects of dietary PFP or EPF supplementation on growth performance, serum biochemical indices, meat quality, and cecal short-chain fatty acids, microbiota, and metabolites in broilers. In Exp. 1, 180 1-day-old Sanhuang broilers (male, 36.17 ± 2.47 g) were randomly allocated into 3 treatments, with 6 replicates in each treatment. The 3 experimental diets included 1 basal diet (control) and 2 PFP-added diets supplemented with 1 and 2% PFP, respectively. The trial lasted for 42 d. In Exp. 2, 144 Sanhuang broilers (male, 112-day-old, 1.62 ± 0.21 kg) were randomly allocated to 3 treatments. Each treatment was distributed among 6 pens, and each pen contained 8 broilers. The 3 treatment diets included: a control diet, a positive control diet supplementing 75 mg/kg chlortetracycline, and the experimental diet supplementing 3% EPF. The trial lasted for 56 d. Results showed that dietary 1 and 2% PFP addition did not affect growth performance in Exp. 1, and the 3% EPF supplementation had a negative effect on ADFI (P < 0.05) in Exp. 2. A decreased serum triglyceride (P < 0.05) in broilers was observed in Exp. 1. Broilers fed EPF had a higher glutathione peroxidase (GSH-Px) (P < 0.05), and lower levels of tumor necrosis factor-α (TNF-α) (P < 0.05) and glucose (P < 0.05) in Exp. 2. We also found that broilers from PFP or EPF-treated treatments had an increased butyrate content and higher microbial diversity in the cecum. The effects of antioxidation, anti-inflammatory function, and elevated SCFAs were confirmed after the microbe and untargeted metabolomic analysis. Dietary EPF supplementation significantly increased the SCFA-generating bacteria, anti-inflammatory-related bacteria, the antioxidant-related and anti-inflammatory-related metabolites. Moreover, dietary 3% EPF addition positively affects the biosynthesis of phenylpropanoids, which strongly correlate with the antioxidant and anti-inflammatory properties. In conclusion, the proper addition level did not affect the growth performance, and the PFP and EPF could improve the antioxidation state, anti-inflammatory activity, and intestinal functions of Sanhuang broilers to some extent.

Efficacy of Traditional Chinese Herbs combined with bioelectrical stimulation on patients with kidney deficiency and blood stasis type thin endometrium: a retrospective observational study.

OBJECTIVE: This study aimed to investigate the efficacy of Traditional Chinese Herbs (TCH) combined with bioelectrical stimulation (BES) on patients with kidney deficiency and blood stasis type thin endometrium. PATIENTS AND METHODS: A retrospective observational study was conducted on 83 patients diagnosed with thin endometrium, treated in our hospital from August 2019 to August 2021. The clinical data of the patients were reviewed, and 60 eligible patients were categorized into two groups based on the treatment they received: the TCH-BES group (n=30, patients received Femoston, TCH and BES treatment) and the control group (n=30, patients received Femoston only). The endometrial thickness (EMT), uterine artery resistance index (RI) and pulsatility index (PI), serum reproductive hormone levels, traditional Chinese medicine (TCM) syndrome scores, and clinical pregnancy outcomes between the two groups were compared. Continuous data were described as mean ± standard deviation (X- ± S). Student's t-test was used for comparison between the two groups and paired-sample t-test was used for comparison within the same group before and after the treatment. RESULTS: A total of 60 patients with thin endometrium, aged 20-35 years (average, 31.67±3.19 years), were included in this study. After the treatment, the EMT, E2 and progesterone (P) levels of the TCH-BES group were higher than that of the control group (p<0.001, p<0.05 and p<0.001, respectively), the PI, RI level and TCM syndrome scores of the TCH-BES group were lower than those of the control group (p<0.001). The clinical efficacy and pregnancy rate in the TCH-BES group were significantly higher than those in the control group (p<0.05). CONCLUSIONS: TCH combined with EBS has a satisfactory efficacy on patients with kidney deficiency and blood stasis type thin endometrium, and improves EMT, E2 and P levels, reduces PI, RI and TCM syndrome, and eventually leads to a favorable clinical pregnancy outcome.

[A new perspective on Su Wen re-collated in the Song Dynasty].

The government of the Northern Song Dynasty collated and annotated Su Wen four times from 1026-1118. It examined a large number of errors in the collated edition by Wang Bing, and corrected the edition. However, for reasons of time and conditions, there still existed some mistakes, even serious ones, such as the selection of the original texts and the determination of the titles and many other details as well. Among these mistakes, the one which seriously prevented learning medical classics for following generations was that the quoted texts from early medical books were modified based on the Su Wen collated by Wang Bing and Jia Yi Jing on Acupuncture and Moxibustion. This led to the distortion of some early important medical books. This paper examines the re-collation of Su Wen by the officials of the Song Dynasty in a specific historical background and environment, focuses on the errors that have not been perceived today, and pays attention to the investigation and analysis of the causes of those errors, so as to provide a reference for collation of ancient medical classics today.

[The concept of traditional chinese medicine:history, theory and empirical research].

The concept of traditional Chinese medicine has different connotations and extensions in different historical periods. This paper examines the formation and development of the concept of traditional Chinese medicine in the perspective of history, theory and empirical research, and explores the internal connection among different medical systems and between medicine and other disciplines. It attempts to re-define the connotation and extension of the concept of traditional Chinese medicine in the context of the new era, provide references for building the medical community of the Chinese nation and promote the standardization of Chinese medicine terminology, advance the cross-disciplinary construction and establishing a new medical system with the characteristics of openness and tolerance, in order to provide the solution, wisdom and power of traditional Chinese medicine for global health in the process of building a community of human health.

Effects of direct-acting antiviral therapy for patients with advanced hepatocellular carcinoma and concomitant hepatitis C-A population-based cohort study.

OBJECTIVE: We analyzed real-world data to elucidate the effects of anti-Hepatitis C virus (HCV) direct-acting antiviral (DAA) therapy on survival in patients with advanced hepatocellular carcinoma (HCC) and concomitant HCV infection treated with sorafenib. MATERIALS AND METHODS: This population-based retrospective cohort study used the Taiwan National Health Insurance Research Database and the Registration System for Patients Treated with Oral Hepatitis C Antivirals to identify patients with advanced HCC and concomitant HCV infection who received initial targeted therapy (sorafenib) in 2018-2019. The overall survival (OS) of the DAA and non-DAA groups were compared using the Kaplan-Meier survival analysis. Propensity score matching was performed using a ratio of 1:4 to reduce confounding between the DAA and non-DAA groups. RESULTS: The study included 1,684 patients (122 DAA and 1,562 non-DAA users) with HCC and concomitant HCV infection who used sorafenib for the first time in 2018-2019. The Kaplan-Meier survival analysis indicated that advanced HCC patients who used DAAs had longer OS compared to non-DAA patients. The mean survival times were 20.7 months for DAA and 12.5 months for non-DAA. Results obtained after propensity matching indicated a significant difference in OS between the DAA and non-DAA groups. CONCLUSIONS: The analysis of big data from the Taiwan National Health Insurance Research Database revealed that advanced HCC patients on sorafenib benefited from DAAs as a treatment for HCV infection. Patients whose HCV infection was cured had better OS.

[A new perspective and discovery of Su Wen noted by Wang Bing].

Wang Bing's perspective included two aspects. One was the annotation of the classical text, focusing on the medical interpretation and the precise interpretation of concepts and terminology, in particular, the annotation of the scriptures related to acupuncture and moxibustion which had a wide and far-reaching influence on the acupuncture and moxibustion literature in the Song Dynasty. Another was the adaptation of classical text which can be divided into two categories: the adaptation for revealing the original meaning and applying esoteric language; the adaptation of his own understanding. In the second type of adaptation, Wang Bing deliberately concealed the supplementary style of "Words written in red".Wang Bing most likely wrote and annotated the "Seven Chapters of Su wen", which was an important pawn in his adaptation of Suwen. In terms of history and logic, Wang Bing's problems in his large-scale adaptation of Suwen look far more than his achievements. The deception and misdirection caused by the second kind of adaptation concealed deliberately by Wang Bing is still unknown.

Real-world results of immune checkpoint inhibitors from the Taiwan National Health Insurance Registration System.

OBJECTIVE: Immune checkpoint inhibitors (ICIs) are a major advance in cancer treatment, but their payment benefits are unclear, resulting in financial risk. In Taiwan, the National Health Insurance Administration (NHIA) has adapted risk-sharing mechanisms to cover ICIs by collecting and assessing real-world evidence, such as case registration data, to adjust benefit packages for each medication, increase payment benefits of ICIs, and enable national health insurance sustainability. PATIENTS AND METHODS: This nationwide, multicenter, retrospective cohort study assessed the real-world use, effectiveness, and safety of ICIs reimbursed by the NHIA for treating multiple advanced cancers in Taiwan. We obtained data mainly from the NHIA Immune Checkpoint Inhibitor Registry Database. RESULTS: Between April 1, 2019, and March 31, 2020, 1644 patients received at least one dose of ICIs. The overall response rate (RR) was 29.1%. The metastatic urothelial carcinoma of patients ineligible for chemotherapy showed the highest RR. The estimated median progression-free survival (PFS) was 2.8 months (95% confidence interval [CI]=2.7-3 months), and renal cell carcinoma showed the longest PFS. The median PFS was reached in patients with most cancers except classic Hodgkin's lymphoma, which had a small sample size. The estimated survival probability was 50%. CONCLUSIONS: Under the national registration tracking system, Taiwan's high-cost drug policy has enabled access to new medicines and maximized patient benefits.

[The version and literature value of 45 volumes of Yixue Gangmu in the Ming Dynasty].

The existing 45 volumes of Yixue Gangmu(, Compendium of Medicine) in Ming dynasty is the most similar to its original book by Lou Ying. The discovery of these volumes is of just as great significance to the study of Yixue Gangmu, as the discovery of The New Version of Sun Zhenren Qianjin Fang (, The Immortal Sun's Precious Formulary) in Song Dynasty was to the study of Beiji Qianjin Yao Fang (, Essential Recipes for Emergent Use Worth A Thousand Gold). The discovery of the 45 volumes of Yixue Gangmu in Ming Dynasty has a unique literature value for the annotation of medical classics, identification and collation of medical books in Jin and Yuan Dynasties.

[Foreign medicinal materials in Bencao Tujing].

Bencao Tujing(, Illustration of Materia Medica) presents the exchange and application of foreign medicine in the middle period of the Northern Song Dynasty. The description Bencao Tujing records foreign medicinal materials from 29 extraterritorial countries, and also recorded some foreign medicinal materials from wide areas such as the Silk Road, the Maritime Silk Road and minority areas. Bencao Tujing systematically recorded foreign varieties before the Song Dynasty which used domestic resources in the Song Dynasty; it also recorded a large number of varieties of domestic and foreign resources, including genuine medicinal materials from abroad. The paintings of some foreign varieties in Bencao Tujing were basically true. However, some figures of foreign medicinal variety have conjecture elements, and some foreign medicinal materials have detailed traits described but no corresponding figures. The book also truthfully recorded that some samples of foreign medicinal materials have not been investigated. Through the Bencao Tujing, it can be deduced that foreign medicinal materials have been integrated into the daily life of the Song Dynasty, and the court of the Song Dynasty paid great attention to the investigation of foreign medicinal materials. Bencao Tujing systematically summarized foreign medicinal materials which were introduced before the Northern Song Dynasty, and provided precious historical materials for studying foreign medicinal materials in the Song Dynasty.

Management of ventral hernia defect during enterocutaneous fistula takedown: practice patterns and short-term outcomes from the Abdominal Core Health Quality Collaborative.

BACKGROUND: An enterocutaneous fistula (ECF) with an associated large hernia defect poses a significant challenge for the reconstructive surgeon. We aim to describe operative details and 30-day outcomes of elective hernia repair with an ECF when performed by surgeons participating in the Abdominal Core Health Quality Collaborative (ACHQC). STUDY DESIGN: Patients undergoing concomitant hernia and ECF elective repair were identified within the ACHQC. Outcomes of interest were operative details and 30-day rates of surgical site infections (SSI), surgical site occurrences requiring procedural intervention (SSOPI), medical complications, and mortality. RESULTS: 170 patients were identified (mean age 60 years, 52.4% females, mean BMI 32.3 kg/m2). 106 patients (62%) had small-bowel ECFs, mostly managed with resection without diversion. 30 patients (18%) had colonic ECFs, which were managed with resection without diversion (14%) or resection with diversion (6%). 100 (59%) had a prior mesh in place, which was removed in 90% of patients. Hernias measured 14 cm ± 7 in width, and 68 (40%) had a myofascial release performed (41 TARs). Mesh was placed in 115 cases (68%), 72% as a sublay, and more frequently of biologic (44%) or permanent synthetic (34%) material. 30-day SSI was 18% (37% superficial, 40% deep), and 30-day SSOPI was 21%. 19 patients (11%) were re-operated: 8 (8%) due to a wound complication and 4 (2%) due to a missed enterotomy. Two infected meshes were removed, one biologic and one synthetic. CONCLUSIONS: Surgeons participating in the ACHQC predominantly resect ECFs and repair the associated hernias with sublay mesh with or without a myofascial release. Morbidity remains high, most closely related to wound complications, as such, concomitant definitive repairs should be entertained with caution.

Non-coated versus coated mesh for retrorectus ventral hernia repair: a propensity score-matched analysis of the Americas Hernia Society Quality Collaborative (AHSQC).

PURPOSE: The outcomes of utilizing anti-adhesive barrier-coated mesh in the retrorectus position during open ventral hernia repair are unknown. We compared the wound-related outcomes between non-coated (NCM) and coated mesh (CM) placed in the retrorectus space. METHODS: Patients undergoing elective, open, clean ventral hernia repair with retrorectus mesh were retrospectively identified in the Americas Hernia Society Quality Collaborative. Propensity score matching was performed based on clinically relevant demographic and operative covariates. The primary outcome was wound morbidity, defined as surgical site infection (SSI), surgical site occurrence (SSO), and SSO requiring procedural intervention (SSOPI). RESULTS: 3609 patients were included (3281 NCM, 328 CM). Following 2:1 propensity score matching, rates of myofascial release remained the only statistically different matching parameter; external oblique releases were performed more frequently in the CM group (8% vs. 15%; p = 0.03). Rates of SSI (3% vs. 4%; p = 0.16) were similar between groups. Increased rates of SSO (13% vs. 18%; p = 0.045) and SSOPI (4% vs. 8%; p = 0.038) were observed in the CM group. The CM group had a higher rate of postoperative seroma (3% vs. 7%; p = 0.027) compared to the NCM group. CONCLUSION: Barrier-coated mesh in the retrorectus position was associated with increased wound morbidity requiring procedural intervention. Due to a lack of clinical benefit, the use of more costly barrier-coated mesh in the retrorectus position is not justified for routine, open ventral hernia repairs at this time.

Mineral requirements in ducks: an update.

Mineral nutrition plays a critical role in growth and bone mineralization in meat ducks as well as reproductive performance in duck layers and duck breeders. In addition to improving production performance parameters, minerals are also essential to support several enzymatic systems to enhancing antioxidant ability and immune function. This review explores the biological function and metabolism of minerals in the body, as well as mineral feeding strategy of various species of ducks. Topics range from mineral requirement to the physiological role of macroelements such as calcium and phosphorus and microelements such as zinc and selenium, etc. As with the improvement of genetic evolution and upgrade of rearing system in duck production, mineral requirements and electrolyte balance are urgent to be re-evaluated using sensitive biomarkers for the modern duck breed characterized by the rapid growth rate and inadequate bone development and mineralization. For duck breeders, mineral nutrition is not only required for maximal egg production performance but also for maintaining normal embryonic development and offspring's performance. Therefore, the proper amounts of bioavailable minerals need to be supplemented to maintain the mineral nutritional state of duck species during all phases of life. In addition, more positive effects of high doses microelements supplementations have been revealed for modern meat ducks subjected to various stresses in commercial production. The nutritional factors of mineral sources, supplemental enzymes, and antinutritional factors from unconventional ingredients should be emphasized to improve the effectiveness of mineral nutrition in duck feed formulation. Organic mineral sources and phytase enzymes have been adopted to reduce the antagonistic action between mineral and antinutritional factors. Therefore, special and accurate database of mineral requirements should be established for special genotypes of ducks under different rearing conditions, including rearing factors, environmental stresses and diets supplemented with organic sources, phytase and VD3.

[Puzzle Solution of the compilation and circulation of Classics on Acupuncture and Plain Questions].

Through mining and collecting the compiling thought of Miraculous Pivot (《》) and Plain Questions (《》), which were handed down from ancient times, it is discovered that these two ancient works refer to two components of one integrity book. With regard to the character and relationship, Miraculous Pivot is the main section and the essence, focusing on theoretic innovation. "Writing" is predominated in its statement. Plain Questions is the supplementary opinions to the main section, containing clinical application and material collection. "Compiling" is predominated in its statement. Both of two works were completed between the late Western Han Dynasty and the Eastern Han Dynasty. The author was a leading scholar and had worked in a national library for a long time. Before the Song Dynasty, Plain Questions had been widely circulated, while the spreading of Miraculous Pivot was limited. In the process of inheritance, some of the content of these two works were lost or supplemented, and the chapters were disarranged or adjusted artificially. But, in general, the original is not distorted seriously, especially the essential section, Miraculous Pivot.

[Preliminary efficacy analysis of Cheng's Giraffe reconstruction after proximal gastrectomy in adenocarcinoma of esophagogastric junction].

Objective: To investigate the safety and feasibility of proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction for the treatment of early Siewert II adenocarcinoma of esophagogastric junction (AEG). Methods: Indication of Cheng's Giraffe esophagogastric reconstruction: (1) Siewert II AEG or Siewert III AEG with diameter < 4 cm; (2) preoperative staging as cT1-2N0M0. A descriptive case series study was carried out. Clinical data of 34 patients with Siewert II AEG undergoing proximal partial gastrectomy and Cheng's Giraffe esophagogastric reconstruction at Department of Abdominal Surgery of Zhejiang Cancer Hospital and Department of Gastrointestinal Surgery, The First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from February to July 2018 were retrospectively collected and analyzed, including 14 cases in IA stage, 11 cases in IIA stage and 8 cases in IIB stage. Brief procedure of Cheng's Giraffe esophagogastric reconstruction was as follows: Firstly, 12 cm long tubular stomach was formed by longitudinal incision 4 cm away from the great curvature of the stomach. Secondly, the gastric fundus and His angle were formed. Finally, the distance from His angle to esophagal-tubular gastric anastomosis should be more than 5 cm. The reflux disease questionare (RDQ) scores, radionuclide gastric emptying scintigraphy, and 24-hour multichannel intraluminal (MII)-pH monitoring technology were used to evaluate postoperative gastric emptying and gastroesophageal reflux. Result: All 34 patients successfully completed proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction, including 13 cases by open surgery and 21 cases by laparoscopic surgery. The operation time was (144.6±39.8) minutes, the blood loss during operation was (35.4±17.2) ml. No laparoscopic case was converted to open surgery and no postoperative complication was observed. The postoperative hospital stay was (8.4±2.5) days. The postoperative RDQ score was 4.4±3.1 one month after operation, and 3.3±2.5 six months after operation. Gastric-half emptying time was (67.0±21.5) minutes, and the residual ratio was (52.2±7.7)% in 1 hour, (36.4±3.1)% in 2 hours and (28.8±3.6)% in 3 hours at postoperative 1-month. The 24-hour MII-pH monitoring at postoperative 2-month revealed the frequency of acid reflux was (12.6±7.9) times, frequency of non-acid reflux was (19.6±9.7) times, DeMeester score was 5.8±2.9. Conclusion: Cheng's Giraffe esophagogastric reconstruction is safe and feasible in the treatment of Siewert type II AEG, and has good dynamic and anti-reflux effects.

Ingenious floral structure drives explosive pollination in Hydrilla verticillata (Hydrocharitaceae).

In explosive pollination, many structures and mechanisms have evolved to achieve high-speed stamen movement. The male flower of the submerged plant Hydrilla verticillata is reported to be able to release pollen explosively some time after leaving the mother plant time, but the mechanism of stamen movement and the related functional structure in this species are unclear. In this study, we observed the male flower structure and pollen dispersal process of H. verticillata. We analysed the stamen movements during the pollen dispersal process and conducted several controlled experiments to study the process of storage and release of elastic potential energy in explosive pollination. When the male flower of H. verticillata is bound to the united bracts, the sepals accumulate elastic potential energy through the expansion of basal extensor cells. After the male flower is liberated from the mother plant, the stamens unfold rapidly with the sepals under adhesion and transfer the elastic potential energy to the filament in seconds. Once stamens unfold to a critical angle, at which the elasticity of the filament just exceeds the adhesion between sepals and anthers, the stamens automatically rebound and release pollen in milliseconds. These results reveal that Catapult-like stamens, spoon-shaped sepals and enclosed united bracts in the spathe together constitute the functional structure in rapid stamen movement of H. verticillata. They ensure that the pollen can be released on the water surface, and thus adapt successfully to the pollen-epihydrophilous pollination.

[Study on anti- fibrotic mechanism of Fuzheng -Huayu formula to suppress autophagy in mice].

Objective: To determine whether the anti-hepatic fibrosis effect of Fuzheng-Huayu formula is related to suppress autophagy in mice. Methods: C57 mice were randomly divided into normal group (N group) and model group. The model group was induced by intraperitoneal injection of carbon tetrachloride to induce liver fibrosis in mice, and the normal group was injected with equal volume of olive oil. After 1 week, the model group was randomly divided into model (M) group, rapamycin (Rapa) group, rapamycin plus chloroquine (Rapa+CQ) group, rapamycin plus salvianolic acid B (Rapa+Sal B) group, rapamycin plus Fuzheng -Huayu formula (Rapa+FZ) group. Each drug group was administered corresponding drugs by gavage on a daily basis, and N group and M group were given the equal amount of drinking water by gavage. After 5 weeks, the mice were sacrificed, and HE and Sirius red staining were used to observe the inflammation and collagen deposition on liver tissue in each group. The hydroxyproline content was determined by alkaline hydrolysis method. Western blotting was used to detect changes in the expression of autophagy in liver tissue and microtubule-associated protein 1 light chain 3II/I (LC3II/I), p62, α-smooth muscle actin (ɑ-SMA) and type I collagen expression. Immunofluorescence staining was used to observe the immunofluorescence localization of ɑ-SMA and LC3B in liver tissues of each group. ). A t-test was used to compare the two independent samples. LSD or Dunnett's T3 test were used to compare the mean of multiple samples. Results: There was no significant difference in N and M groups in terms of body weight. The body weight of the mice in each drug group decreased significantly (F = 14.041, P < 0.001). The liver/spleen /body weight ratios of each drug group and M group were significantly higher than the N group (F = 26.992, 6.589, P < 0.001). The expression of p62 protein in the liver tissue of mice in each drug group was lower than M group, and the difference between Rapa group and Rapa+Sal B group (F = 3.085, P = 0.039, 0.003) was statistically significant, while that of Rapa + Sal B group was lower. Compared with group M, the expression of LC3B II in Rapa group was significantly higher (F = 7.514, P = 0.01). Immunofluorescence staining showed that LC3B and α-SMA CO-stained cells were absent in the liver of mice in N group, and co-stained cells were found in the liver of mice in M group. The co-stained cells in the liver of mice in each drug group were significantly higher than M group, and the co-stained cells in Rapa+FZ group were fewer. Compared with the N group, the collagen deposition of M group and each drug group was significantly increased; the collagen deposition of each drug group was lower than that of the M group. There was no statistically significant difference between each drug group. Compared with N group (77.75 + 48.79), hydroxyproline in liver tissue of mice in M group was significantly increased (293.48 + 84.43) (F = 3.015, P = 0.005), and the content of hydroxyproline in liver tissue of mice in each drug group was lower than M group, but the difference was not statistically significant (F = 0.750, P = 0.573). Compared with the N group, the expressions of α-SMA and type I collagen in the M group were significantly increased (F = 27.718, 18.893, P < 0.01). The expression of α-SMA in Rapa group and Rapa+Sal B group was similar to M group, while Rapa + CQ group and Rapa + FZ group were significantly lower than Rapa group and M group (P < 0.01). The expression of type I collagen in Rapa + CQ group was significantly higher than Rapa group (P = 0.017), while the expression of type I collagen in Rapa + FZ group was significantly lower than M group (P = 0.013). Conclusion: Autophagy of hepatic stellate cells was observed in carbon tetrachloride-induced liver fibrosis model. Rapamycin can promote autophagy in hepatocytes and hepatic stellate cells. Fuzheng-Huayu formula and Salvianolic Acid B might antagonize the effect of rapamycin on autophagy.

[The significance and latest progress of extrathyroidal extension of thyroid cancer].

Extrathyroidal extension of thyroid cancer has been an important adverse factor affecting the prognosis of patients. According to the latest NCCN (National Comprehensive Cancer Network) guidelines, extrathyroidal extension is the surgical guide fortotal thyroidectomy in newly diagnosed patients, and its incidence in differentiated thyroid cancer is 5%-34%, belonging to T3-T4 stage.In the eighth edition of thyroid cancer AJCC staging, the T3 stage was first divided into T3a (tumor>4 cm and limited to the thyroid) and T3b (gross extrathyroidal extension invading only strap muscles from a tumor of any size), and the "minimal extrathyroidal extension(tumor invasion intoperithyroidal soft tissue or strap muscle invasion)"of the seventh edition was removed from the T stage and changed to the gross extrathyroidal extension invading only strap muscles, but there is still much controversy. It can be seen that different degrees of "extrathyroidal extension" have significant differences in the survival and prognosis of thyroid cancer. This article reviews the latest research progress of extrathyroidal extension, and discusses the significance and clinical research progress of it.
