Research strategies and applications of functional metabolomics in anti-depressive mechanisms of traditional Chinese medicine / 药学学报

Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

Anatomical classification of and laparoscopic surgery for left-sided colorectal cancer with persistent descending mesocolon / 中华胃肠外科杂志

Objective: To investigate anatomical morphology and classification of persistent descending mesocolon (PDM) in patients with left-sided colorectal cancer, as well as the safety of laparoscopic radical surgery for these patients. Methods: This is a descriptive study of case series. Relevant clinical data of 995 patients with left colon and rectal cancer who had undergone radical surgery in Fujian Medical University Union Hospital from July 2021 to September 2022 were extracted from the colorectal surgery database of our institution and retrospectively analyzed. Twenty-four (2.4%) were identified as PDM and their imaging data and intra-operative videos were reviewed. We determined the distribution and morphology of the descending colon and mesocolon, and evaluated the feasibility and complications of laparoscopic surgery. We classified PDM according to its anatomical characteristics as follows: Type 0: PDM combined with malrotation of the midgut or persistent ascending mesocolon; Type 1: unfixed mesocolon at the junction between transverse and descending colon; Type 2: PDM with descending colon shifted medially (Type 2A) or to the right side (Type 2B) of the abdominal aorta at the level of the origin of the inferior mesentery artery (IMA); and Type 3: the mesocolon of the descending-sigmoid junction unfixed and the descending colon shifted medially and caudally to the origin of IMA. Results: The diagnosis of PDM was determined based on preoperative imaging findings in 9 of the 24 patients (37.5%) with left-sided colorectal cancer, while the remaining diagnoses were made during intraoperative assessment. Among 24 patients, 22 were male and 2 were female. The mean age was (63±9) years. We classified PDM as follows: Type 0 accounted for 4.2% (1/24); Type 1 for 8.3% (2/24); Types 2A and 2B for 37.5% (9/24) and 25.0% (6/24), respectively; and Type 3 accounted for 25.0% (6/24). All patients with PDM had adhesions of the mesocolon that required adhesiolysis. Additionally, 20 (83.3%) of them had adhesions between the mesentery of the ileum and colon. Twelve patients (50.0%) required mobilization of the splenic flexure. The inferior mesenteric artery branches had a common trunk in 14 patients (58.3%). Twenty-four patients underwent D3 surgery without conversion to laparotomy; the origin of the IMA being preserved in 22 (91.7%) of them. Proximal colon ischemia occurred intraoperatively in two patients (8.3%) who had undergone high ligation at the origin of the IMA. One of these patients had a juxta-anal low rectal cancer and underwent intersphincteric abdominoperineal resection because of poor preoperative anal function. Laparoscopic subtotal colectomy was considered necessary for the other patient. The duration of surgery was (260±100) minutes and the median estimated blood loss was 50 (20-200) mL. The median number of No. 253 lymph nodes harvested was 3 (0-20), and one patient (4.2%) had No.253 nodal metastases. The median postoperative hospital stay was 8 (4-23) days, and the incidence of complications 16.7% (4/24). There were no instances of postoperative colon ischemia or necrosis observed. One patient (4.2%) with stage IIA rectal cancer developed Grade B (Clavien-Dindo III) anastomotic leak and underwent elective ileostomy. The other complications were Grade I-II. Conclusions: PDM is frequently associated with mesenteric adhesions. Our proposed classification can assist surgeons in identifying the descending colon and mesocolon during adhesion lysis in laparoscopic surgery. It is crucial to protect the colorectal blood supply at the resection margin to minimize the need for unplanned extended colectomy, the Hartmann procedure, or permanent stomas.

Application value of Hisense computer-assisted surgery system three-dimensional reconstru-tion in precision treatment of pediatric liver tumors / 中华消化外科杂志

Objective:To investigate the application value of Hisense computer-assisted surgery system (CAS) three-dimensional reconstruction in the precision treatment of pediatric liver tumors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 82 children with liver tumors who were admitted to Affiliated Hospital of Qingdao University from January 2013 to September 2021 were collected. There were 39 males and 43 females, aged 13(19)months. Children underwent upper abdominal dynamic enhanced computed tomography (CT) examination, and three-dimensional reconstruction was performed on CT images of arterial, equili-brium and venous phases with Hisense CAS. Surgical feasibility and scheme were evaluated and conducted based on the results of upper abdominal dynamic enhanced CT examination, and then revised according to three-dimensional reconstruction results of Hisense CAS. Observation indicators: (1) comparison of surgical scheme between two-dimensional enhanced CT images and three-dimensional reconstruction results of Hisense CAS; (2) intraoperative and postoperative situations; (3) follow-up. Follow-up was conducted by outpatient examination to detect postoperative compli-cations and residual liver compensation up to November 2021. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(IQR) or M(range). Count data were described as absolute numbers or percentages. Results:(1) Comparison of surgical scheme between two-dimensional CT images and three-dimensional reconstruction results of Hisense CAS. ① Based on the two-dimensional CT images, 42 cases of 82 children could undergo one-stage resection and 40 children could not. However, based on the three-dimensional reconstruction results of Hisense CAS, 48 cases of 82 children could undergo one-stage resection and 34 children could not. There were 6 children with one-stage resection feasibility based on the three-dimensional reconstruction results of Hisense CAS rather than the two-dimensional CT images. For the 34 children undergoing chemotherapy firstly, 31 cases had surgical feasibility after chemotherapy based on the two-dimensional CT images and 3 cases could not undergo surgery because of unapparent tumor regression or tumor surrounding impor-tant vessels. However, the 34 children had surgical feasibility after chemotherapy based on the three-dimensional reconstruction results of Hisense CAS. The revision rate of surgical feasibility was 11.0%(9/82) for the 82 children. ② Based on the two-dimensional CT images, 15 cases of 82 children underwent liver left lobectomy, 21 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 13 cases underwent extended left hemihepatectomy, 23 cases underwent extended right hemihepatectomy, 3 cases underwent segmental hepatectomy. However, based on the three-dimensional reconstruction results of Hisense CAS, 20 cases of 82 children underwent liver left lobectomy, 29 cases underwent liver right lobectomy, 7 cases underwent mesohepatectomy, 7 cases underwent extended left hemihepatectomy, 14 cases underwent extended right hemihepatectomy, 5 cases underwent segmental hepatectomy. The revision rate of surgical scheme was 36.6%(30/82) for the 82 children. (2) Intraoperative and postoperative situations. The operation time, volume of intraoperative blood loss, duration of postoperative hospital stay of the 82 children were (182±18)minutes, 20(10)mL, (10.2±1.9)days, respectively. (3) Follow-up. All the 82 children were followed up for 10 (range, 2?18)months. There was no obvious complication occurred to the 82 children after surgery, and the residual liver can satisfy the liver compensation of body. All the children survived well.Conclusion:Three-dimensional reconstruction of Hisense CAS is conducive to judging the surgical feasibility and formulation of accurate surgical plan of children with liver tumors.

Identification of a novel coronavirus causing severe pneumonia in human: a descriptive study / 中华医学杂志(英文版)

Background: Human infections with zoonotic coronaviruses (CoVs), including severe acute respiratory syndrome (SARS)-CoV and Middle East respiratory syndrome (MERS)-CoV, have raised great public health concern globally. Here, we report a novel bat-origin CoV causing severe and fatal pneumonia in humans. Methods: We collected clinical data and bronchoalveolar lavage (BAL) specimens from five patients with severe pneumonia from Jin Yin-tan Hospital, Wuhan, Hubei province, China. Nucleic acids of the BAL were extracted and subjected to next-generation sequencing. Virus isolation was carried out, and maximum-likelihood phylogenetic trees were constructed. Results: Five patients hospitalized from December 18 to December 29, 2019 presented with fever, cough, and dyspnea accompanied by complications of acute respiratory distress syndrome. Chest radiography revealed diffuse opacities and consolidation. One of these patients died. Sequence results revealed the presence of a previously unknown β-CoV strain in all five patients, with 99.8–99.9% nucleotide identities among the isolates. These isolates showed 79.0% nucleotide identity with the sequence of SARS-CoV (GenBank NC_004718) and 51.8% identity with the sequence of MERS-CoV (GenBank NC_019843). The virus is phylogenetically closest to a bat SARS-like CoV (SL-ZC45, GenBank MG772933) with 87.6–87.7% nucleotide identity, but is in a separate clade. Moreover, these viruses have a single intact open reading frame gene 8, as a further indicator of bat-origin CoVs. However, the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV, indicating that these viruses might use the same receptor. Conclusion: A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.

Relationship between driver gene mutation and clinicopathological features in 300 cases of non-small cell lung cancer based on next generation sequencing / 临床与实验病理学杂志

Purpose To explore the mutation characteristics of common driver genes in non-small cell lung cancer (NSCLC) and its relationship with clinicopathological features.Methods Next generation sequencing (NGS) was used to detect the mutations of common driving genes such as EGFR, KRAS, ALK, ROS1, BRAF, MET, RET and HER-2 in 300 paraffin-embedded NSCLC tissues. Results In 300 patients with NSCLC, the mutation rates of EGFR, KRAS, ALK, ROS1, BRAF, MET, RET, HER-2 were 52.00％, 10.33％, 6.67％, 1.67％, 3.67％, 3.33％, 1.00％, and 2.33％, respectively. A case of EGFR 21 exon L858 R mutation was combined with LINCO1446-EGFR gene fusion. EGFR 20 th exon C797 S and T790 M existed in cis or trans form and merged with EGFR sensitive mutations in 1 case each. 3 cases of EGFR gene point mutation was associated with MET gene copy number amplification. EGFR mutations were more commonly detected in non-smoking women with lung adenocarcinoma (P<0.05).KRAS mutations were more commonly found in smoking men (P<0.05). ALK mutations were associated with age (P<0.05), and more commonly noted in patients younger than 60 years.ROS1 fusion mutations were associated with gender (P<0.05), more commonly detected in women. BRAF, MET, RET, and HER-2 gene mutations were not associated with gender, age, smoking, histological type, and c TNM stage. Conclusion EGFR can coexist with other driver gene mutations. Gene mutations and clinicopathological features like gender, age, smoking, and histological types have corresponding links. The incidence of BRAF, MET, RET, and HER-2 mutations is low, and its clinical significance remains to be explored. Coexisting gene mutations and rare mutations discovered by NGS should be taken seriously.

Safety and effectiveness of autologous blood transfusion after total hip arthroplasty / 中国组织工程研究

BACKGROUND: Autologous blood transfusion device has been widely used in the clinic, reduces al ogeneic blood transfusion, and avoids the occurrence of blood transfusion complications, and effectively improves the patient’s blood safety, but the application of autologous blood transfusion after total hip arthroplasty has been seldom reported. OBJECTIVE: To discuss the safety and effectiveness of autologous blood transfusion after total hip arthroplasty. METHODS: 200 patients were treated by primary unilateral total hip arthroplasty from March 2013 to March 2015. They were randomly divided into two groups. 127 patients in the autologous blood transfusion group received autologous blood transfusion by a drainage tube. 73 patients in the negative pressure drainage bal group received a negative pressure drainage tube. The standard for al ogeneic blood transfusion after replacement was hemoglobin 0.05). Hemoglobin levels were significantly higher in the autologous blood transfusion group than in the negative pressure drainage bal group at 1 day after replacement (P < 0.05). In the autologous blood transfusion group, autologous blood transfusion volume was averagely 324.2 mL. Al ogeneic blood transfusion volume was averagely 146.7 mL in 31 patients. No reaction was found after autologous blood transfusion. In the negative pressure drainage bal group, 49 patients received al ogeneic blood transfusion (averagely 261 mL). The volume and proportion of al ogeneic blood transfusion were significantly lower in the autologous blood transfusion group than in the negative pressure drainage bal group (P < 0.05). Among patients receiving al ogeneic blood transfusion, seven patients affected pyrogenetic reaction during blood transfusion. These findings suggested that autologous blood transfusion is simple and effective, can effectively reduce the volume and reaction of al ogeneic blood transfusion after total hip arthroplasty and avoid blood-borne diseases, with good prospects.

Significance of high sensitivity C-reactive protein level for predicting risk of nonalcoholic fatty liver in type 2 diabetes mellitus patients / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the significance of high sensitivity C-reactive protein (hsCRP) levels in serum for detecting type 2 diabetes mellitus (T2DM) patients at risk of developing nonalcoholic fatty liver (NAFLD).</p><p><b>METHODS</b>Individuals with T2DM (n = 9489) were recruited from the Kailuan Company between 2006 and 2007 for the first phase of this community-based prospective cohort study. For the second phase of the study, the original cohort was recruited for follow-up (at two years from each subject's original enrollment date (baseline)). The total followed-up subjects (n = 2802; 2344 males, 458 females, 22-88 years old) were categorized into quartiles according to baseline measurements of serum hsCRP levels (less than or equal to 0.30, > 0.30-0.60, > 0.60-1.92 and > 1.92 mg/L) and used to determine the relationship between change in incidence rates of NAFLD and predictive value of baseline serum hsCRP levels by logistic regression analysis.</p><p><b>RESULTS</b>Twenty-nine percent (n = 813) of the followed-up subjects developed NAFLD. The incidence (%) of NAFLD at the two-year follow-up had increased in conjunction with the level of serum hsCRP detected at baseline (quartile 1: 22.5%, 2: 27.3%, 3: 32.1%, and 4: 34.3%; all, P less than 0.01). It was found that the subjects in the highest quartile had an increased risk of NAFLD (odds ratio (OR) = 1.80, 95% confidence interval (CI): 1.42-2.28, P less than 0.01), as compared with those in the lowest quartile. Moreover, when the regression model was adjusted for baseline factors of age, sex, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting serum glucose, and body mass index, the risk of NAFLD remained significantly higher for the highest quartile (vs. the lowest quartile; OR = 1.49, 95% CI: 1.16-1.91, P less than 0.01).</p><p><b>CONCLUSION</b>Serum hsCRP levels may be predictive of development of NAFLD in individuals with type 2 diabetes mellitus. The risk of NAFLD increases in parallel with increasing levels of serum hsCRP.</p>

Efficacy and safety of sunitinib on patients with imatinib-resistant gastrointestinal stromal tumor / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the efficacy and safety of sunitinib on the management of gastrointestinal stromal tumors (GIST) patients with imatinib resistance.</p><p><b>METHODS</b>Clinical data of 48 patients with imatinib-resistant GIST received sunitinib therapy from May 2008 to April 2012 in the Union Hospital of Fujian Medical University were analyzed retrospectively. Eighteen patients received 50 mg/d of sunitinib in a protocol of 4/2 (4 weeks on and 2 weeks off) [50 mg/d (4/2)], and 30 patients received a protocol of 37.5 mg of sunitinib continuous daily dose (37.5 mg/d CDD).</p><p><b>RESULTS</b>The median duration of sunitinib administration of all the 48 patients was 56 weeks, and the short-term efficacy was evaluated at 24 weeks after the initial treatment according to the Choi criteria. The response rate was 27.1% (13/48), including 1 case with complete response (CR), 12 cases with partial response (PR), and 21 cases with stationary disease (SD). The disease control rate was 70.8% (34/48). The mean follow-up time of 48 patients was 89 weeks. The median progression-free survival (PFS) and overall survival (OS) were 48 weeks and 92 weeks respectively. Stratified analyses indicated that the median PFS of patients previously treated by imatinib 400 mg/d and >400 mg/d were 53 weeks and 35 weeks respectively (P=0.018), and the median OS of these two groups were 157 weeks and 71 weeks respectively (P=0.003). Patients with exon 11 mutations had a significantly shorter OS compared with those with exon 9 mutations (71 weeks vs 157 weeks, P=0.008). Hand-foot syndrome was the most common adverse effect (25/48, 52.1%), followed by nausea (24/48, 50.0%), fatigue (23/48, 47.9%), neutropenia(21/48, 41.7%). The sub-group analysis of two protocols of sunitinib administration showed that the incidence of diarrhea and hand-foot syndrome were higher in 50 mg/d (4/2) group than those in 37.5 mg/d CDD group (P=0.027, P=0.048).</p><p><b>CONCLUSIONS</b>Sunitinib is effective for the patients with imatinib-resistant GIST. After 400 mg/d imatinib treatment failure, sunitinib should be prescribed instead of increased dosage of imatinib. Patients with KIT exon 9 mutations present better prognosis than those with KIT exon 11 mutations. The protocol of sunitinib 37.5 mg/d CDD possesses better safety.</p>

The result showed that, compared with Group OR, Group LR had lower overall rate of postoperative complication (OR=0.76, 95%CI:0.62-0.92, P<0.01), lower rate of postoperative intestinal obstruction (OR=0.53, 95%CI:0.35-0.80, P<0.01), lower rate of incision complications (OR=0.43, 95%CI:0.28-0.67, P<0.01), similar incidence of anastomotic bleeding and fistula, and similar incidence of bleeding in abdominal cavity and pelvic cavity (all P>0.05).</p><p><b>CONCLUSIONS</b>The overall rate of postoperative complications of laparoscopic resection for mid-low rectal carcinoma is obviously lower than that of open resection. Laparoscope can be applied safely in the resection of mid-low rectal carcinoma.</p>

Comparison of remifentanil induction of general anesthesia in cesarean section of different anesthesia methods / 中国医师进修杂志

Objective To explore the feasibility of reducing induction dose of remifentanil,deepening anesthesia and intubation after umbilical removal and its effect on maternal,neonatal and anesthesiologists during cesarean section.Methods Thirty cases of ASA Ⅰ-Ⅱ scheduled for elective cesarean section were divided into three groups according random digits table method with 10 cases each.The induction dose of remifentanil was 1.0,1.5,1.0 μ g/kg in group Ⅰ,group Ⅱ,group Ⅲ.Group Ⅰ and group 11 received routine procedure after induction of anesthesia,intubation,while group Ⅲ received anesthesia umbilical removal.Systolic pressure (SBP),diastolic pressure (DBP) and heart rate (HR) were recorded before induction of anesthesia,skin incision and immediately intubation.And the fetal childbirth time,intubation time and neonatal Apgar score at 1,5,10 min were recorded.Results Three anesthesia procedures could meet the requirements of cesarean section.The SBP,DBP and HR at skin incision in group Ⅰ and group Ⅲ were significantly higher than those at before induction of anesthesia [group Ⅰ:(136.5 ±9.7) mm Hg (1 mm Hg=0.133 kPa) vs.(113.5 ±7.8) mm Hg,(96.5 ±9.1) mm Hg vs.(74.2 ±6.0)mm Hg,(98.5 ± 8.7) times/min vs.(81.2 ± 8.4) times/min; group Ⅲ:(138.1 ± 11.4) mm Hg vs.(118.7 ±9.9) mm Hg,(90.1 ±9.9) mm Hg vs.(77.3 ±7.9) mm Hg,(100.3 ±9.0) times/min vs.(81.7 ±9.2)times/min],there were statistical differences (P ＜ 0.05).The SBP,DBP and HR at immediately intubation in group Ⅲ were significantly lower than those in group Ⅰ andgroup Ⅱ [(97.6±10.1)mmHgvs.(138.9±11.2) and (130.1 ± 4.5) mm Hg,(80.1 ± 5.5) mm Hg vs.(97.7 ± 8.9) and (82.0 ± 8.6) mm Hg,(80.4 ±7.8) times/min vs.(99.3 ± 12.2) and (95.9 ± 9.6) times/min],there were statstical differences (P ＜ 0.05).There was no statistical difference in fetal childbirth time among the 3 groups (P＞ 0.05).The neonatal Apgar score at 1 min in group Ⅱ was significantly lower than that in group Ⅰ and group Ⅲ [(7.4 ± 0.9) scores vs.(8.8 ± 0.6),(8.9 ± 0.6) scores],there was statistical difference (P ＜ 0.05).The intubation time in group Ⅲ was significantly longer than that in group Ⅰ andgroup Ⅱ [(8.5±l.8) min vs.(3.0±0.5),(2.8±0.6)min],there was statistical difference (P＜ 0.05),but the intubation time in group Ⅲ was completed within 10 min.Conclusions Using the protocol of remifentanil 1.0 p g/kg induction,midazolam 2 mg,fentanyl 0.2 mg deepening after the umbilical removal can effectively avoid the effect of remifentanil on neonatal 1 min Apgar score,decrease the intubation stress with no effect on anesthesiologists.This method is simple,method of anesthesia for elective cesarean section.

Fruit intake and gastric cancer: a Meta-analysis study / 中华健康管理学杂志

Objective To assess the relationship between fruit intake and gastric cancer.Methods Articles published during January 2001 and October 2012 that assessed the relationship between fruit intake and gastric cancer were searched on PubMed,Ovid and Willey database.Adjusted relative risk (RR) and 95％ confidence intervals (CI) were calculated by using fixed-effect or random-effect model.Variants of subgroup analysis included living regions,followup duration,and adjusted factors.Results A total of 3679 gastric cancer patients and 1 173 859 subjects from 7 prospective cohorts were included in this metaanalysis,and the pooled RR was 0.89 (95％ CI:0.78-1.01).In the subgroup analysis,the pooled RR in the 10-year followup group was 0.94 (95％ CI:0.85-0.99) before age,cigarette smoking and alcohol drinking were adjusted (RR =0.81,95％ CI:0.54-0.99).Conclusion Fruit intake may prevent the development of gastric cancer.

Discussions on basic medical insurance management for those seeing doctors out of hometown in China / 中华医院管理杂志

A consensus remains unsettled yet for basic medical insurance and common protocols on managing patients seeing doctors out of their hometown.This results in such setbacks as difficulty in seeing doctors elsewhere for those covered and in unaffordable financial burden,as well as medical insurance fraud,lack of information sharing among social insurance authorities,and difficulty of supervision.This study described the status quo of seeding doctors elsewhere under China's basic medical insurance system,and analyzed problems found in the management framework.On such basis,authors proposed such recommendations as unified management system for seeding doctors elsewhere,network information sharing for medical insurance information,and networked settlement for medical expenses for basic medical insurance.These measures should be carried out as per general requirements for health reform stage by stage.
