ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi， so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry（HS-SPME-GC-MS） combined with Smart aroma database and National Institute of Standards and Technology（NIST） database were used to characterize the aroma components in different parts of N. jatamansi， and the aroma components were quantified according to relative response factor（RRF） and three internal standards， and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis（OPLS-DA） and cluster thermal analysis based on variable importance in the projection（VIP） value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose， and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data， and the rapid identification model of different parts of N. jatamansi was established by principal component analysis（PCA）， discriminant factor alysis（DFA）， soft independent modeling of class analogies（SIMCA） and statistical quality control analysis（SQCA）. ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi， of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components， the contents of five components（ethyl isovalerate， 2-pentylfuran， benzyl alcohol， nonanal and glacial acetic acid，） in the aboveground part of N. jatamansi were significantly higher than those in the underground part（P<0.01）， the contents of β-ionone， patchouli alcohol， α-caryophyllene， linalyl butyrate， valencene， 1，8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part（P<0.01）. Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82， and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted， respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%， the validation score of the SIMCA model for discrimination of the two parts was 99， and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose（PCA， DFA， SIMCA and SQCA） can realize the rapid identification of different parts of N. jatamansi. Combining the two results， it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

Hemophilic arthritis(HA),caused by recurrent bleeding,can seriously affect patient quality of life and consumes extensive social and medical resources.There is thus a need to establish an animal model of HA for research;however,this is limited by ethical requirements.Here we review the recent literature and summarize research progress into animal models of HA at home and abroad,from the aspects of species selection,modeling method,histopathology,and imaging evaluation method.Species selection includes rodents such as mice,New Zealand rabbits,beagles,miniature pigs,and crab-eating macaques.Modeling method comprise gene knockout trauma models,gene knockout spontaneous models,and injection models.Among these,the gene knockout spontaneous model closely mimics the pathological process of spontaneous bleeding and concurrent arthritis in human HA,making it more relevant to human HA.However,due to high modeling costs,phenotypic instability,and low survival rates,this model is not the preferred choice for animal experimental studies.In contrast,gene knockout trauma models exhibit characteristics such as short modeling time,strong stability,and high success rates,thus being widely utilized in animal experimental research.Evaluation of HA models involves various imaging method including MRI,micro-CT,MSKUS/PD,in addition to various gross scoring method.By reviewing the progress of HA model research,more experimental evidence is provided for investigating the pathogenesis and validating the efficacy of HA treatments,thereby compensating for the lack of clinical data,particularly in the field of traditional Chinese medicine therapy.

Objective To explore the effect of the nursing intervention for Internet+whole course breastfeeding support based on lactation physiology on exclusive breastfeeding of cesarean section women.Methods Using the convenience sampling method,198 women who were from prenatal examination to delivery in the Obstetrical Department of a tertiary hospital in Nanning city from July 2022 to February 2023 were selected,with 99 women in each group.The experimental group adopted the nursing intervention for Internet+whole course breastfeeding support based on lactation physiology,while the control group adopted routine nursing care.The rates of exclusive breastfeeding within 6 months,breastfeeding or milking frequency within 3 days postpartum,incidence of nipple pain,breastfeeding knowledge scores,and breastfeeding self-efficacy scores were compared between the 2 groups.Results No shedding occurred in both groups.The exclusive breastfeeding rates in the experimental group at postpartum 3 days,14 days,42 days,4 months,and 6 months were higher than that in the control group.The comparison of the rates of exclusive breastfeeding between 2 groups at different time points showed that the intergroup effect,time effect and interaction effect were statistically significant(P＜0.05).The 2 groups were stratified by maternal and child separation,and the rates of exclusive breastfeeding of the experimental group at postpartum 42 days,4 months and 6 months were higher than that of the control group(P＜0.05).The frequency of breastfeeding or milking within 3 days postpartum,incidence of nipple pain,breastfeeding knowledge scores,and breastfeeding self-efficacy scores were higher in the experimental group than those in the control group(P＜0.05).Conclusion The nursing intervention for Internet+whole course breastfeeding support based on lactation physiology can improve the compliance of lactation behavior in cesarean section women and promote the establishment of lactation,which can significantly improve the rate of exclusive breastfeeding within 6 months.

Objective:This study aims to explore the application value of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors.Methods:We retrospectively analyzed the clinical data of 15 patients with complex adrenal tumors treated at the General Hospital of Southern Theater Command from May 2022 to June 2023. The cohort comprised 5 males and 10 females with an average age of (47.6±7.8) years and a body mass index (BMI) of 26.5 (23.8-27.9) kg/m 2. Among the patients, 3 had a BMI ≥28 kg/m 2, 2 had diabetes, 6 had hypertension, and 1 had coronary heart disease. Preoperative endocrine hormone examination revealed abnormal blood catecholamines in 5 cases and abnormal blood cortisol in 2 cases. Ultrasound and CT scans indicated that 9 tumors were located on the left side and 6 on the right, with 4 cases showing tumor compression on adjacent large blood vessels or organs. The average tumor diameter was (7.61±2.79) cm, with 10 cases having a diameter ≥ 6 cm. All patients underwent laparoscopic adrenalectomy assisted by robots through the transperitoneal approach. The surgeries were performed in a lateral position under general anesthesia. The "liftoff" modular method was utilized to separate the treatment of adrenal tumors into lateral, medial, dorsal, cephalic, and adrenal renal plane sides. Tumors were appropriately manipulated during the operations to achieve a "liftoff" shape. Different modular dissociation steps were adopted based on the size and location of the left and right adrenal tumors. The left adrenal gland was dissected in the order of medial and dorsal, adrenal renal plane side, and lateral and cephalic sides, while the right adrenal gland was dissected in the order of lateral and dorsal, adrenal renal plane side, and medial and cephalic sides. Postoperative related indicators and follow-up status of patients were recorded and analyzed. Results:All 15 surgeries were successfully completed without any conversions to open adrenalectomy, with an average operation time of 118 (102-130) minutes and an average intraoperative blood loss of 102 (69-163) ml. The postoperative drainage time was 4 (3-5) days, and the postoperative hospital stay was 6 (4-7) days. The postoperative pathological diagnoses included 5 cases of pheochromocytoma, 3 cases of macronodular adrenal hyperplasia, 6 cases of adrenocortical adenoma, and 1 case of myelolipoma. Follow-up for 6-12 months after surgery showed good recovery and no recurrence.Conclusions:The application of the "liftoff" modular method in robot-assisted laparoscopic surgery for complex adrenal tumors is safe and feasible. It efficiently aids in tumor removal and holds significant clinical application value.

Objective:To explore the efficacy of precise and empirical bismuth-containing quadruple therapy guided by clarithromycin sensitivity testing in the first eradication of Helicobacter pylori ( H. pylori) in Ningxia. Methods:From August 12, 2022 to March 22, 2023, 600 patients diagnosed as H. pylori-positive by 14C-urea breath test ( 14C-UBT) for the first time in People′s Hospital of Ningxia Hui Autonomous Region, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region, Zhongwei People′s Hospital, Yanchi County People′s Hospital, and Pingluo People′s Hospital were selected, and divided into empirical treatment group (hereinafter referred to as the empirical group), genetic testing group (hereinafter referred to as the genetic group), and drug sensitivity testing group (hereinafter referred to as the drug sensitivity group) by using random number table with 200 patients in each group. The empirical group did not undergo drug sensitivity testing and genetic testing, while the genetic and drug sensitivity groups were confirmed to be sensitive to clarithromycin through genetic testing and drug sensitivity testing, and the patients with drug-resistant were excluded, respectively. All the patients of the 3 groups received the same clarithromycin bismuth-containing quadruple therapy. Intention-to-treat (ITT) and per-protocol (PP) analyses were performed to compare the eradication rates of H. pylori among 3 groups. Cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER) were used for cost-effectiveness and sensitivity analysis based on the ITT. Chi-square test was used for statistical analysis. Results:There were 200, 126, and 168 patients included in the empirical group, genetic group, and drug sensitivity group in ITT analysis, and 190, 123, and 164 patients were enrolled in the 3 groups in PP analysis, respectively. The results of ITT analysis showed that the eradication rates of H. pylori in the empirical group, genetic group, and drug sensitivity group were 80.5% (161/200), 94.4% (119/126), and 95.2% (160/168), respectively. The results of PP analysis indicated that the eradication rates of H. pylori in the 3 groups were 84.7% (161/190), 96.7% (119/123), and 97.6% (160/164), respectively, and the differences were statistically significant ( χ2=25.39 and 24.93, both P<0.001). The H. pylori eradication rates of genetic group and drug sensitivity group were both higher than that of empirical group in ITT and PP analysis( χ2=12.40, 17.80, 11.42, and 17.13; all P<0.001). The cost-effectiveness analysis showed that the direct treatment cost of the empirical group, genetic group, and drug sensitivity group was 400.8, 729.2, and 779.2 yuan, respectively, and the CER was 4.98, 7.72, and 8.18 yuan/%, respectively. Compared to the empirical group, the ICER of the genetic group and drug sensitivity group was 23.6 and 25.7 yuan/%, respectively. The sensitivity analysis demonstrated that, when the cost of genetic testing reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 21.8 or 25.5 yuan/%, respectively. When the cost of drug sensitivity testing reduced or increased by 20%, the ICER of the drug sensitivity group compared to the empirical group was 23.3 or 28.2 yuan/%. When the cost of gastroscopy reduced or increased by 20%, the ICER of the genetic group compared to the empirical group was 20.8 or 26.5 yuan/%, and the ICER of the drug sensitivity group compared to the empirical group was 23.0 or 28.4 yuan/%, respectively. Conclusion:In Ningxia, if the clarithromycin bismuth-containing quadruple regimen is applied as the first H. pylori eradication regimen, in order to achieve the clinical eradication efficacy of H. pylori, and the patients can accept an additional payment of 23.6 or 25.7 yuan for each 1% increasing in the H. pylori eradication rate, then the precision treatment after clarithromycin resistance test is recommended.

Total mesorectal excision is the standard surgical procedure for rectal cancer. Based on this, the intersphincteric resection and conformal sphincter-preserving operation have pushed the sphincter-preserving surgery for ultra-low rectal cancer to the limit. However, no matter what kind of surgery, patients still need to face stoma or anal dysfunction, which seriously affect the quality of life. The "watch and wait " strategy for patients who achieve clinical complete response after neoadjuvant chemoradiotherapy has provided novel therapeutic method for rectal cancer, making non-surgical treatment possible. Total neoadjuvant therapy has expanded the application of the watch and wait strategy and has been written to the guidelines. Meanwhile, the rise of immuno-therapy has changed the treatment pattern of tumors. It has been the first-line treatment for advanced colorectal cancer with mismatch repair deficiency or microsatellite instability-high. As for patients with proficient mismatch repair or microsatellite stability, researches focus on how to improve the effect of neoadjuvant radiotherapy combined with immunotherapy, so that more patients with low rectal cancer have the opportunity to achieve clinical complete response and enter the watch and wait procedure, which will achieve the purpose of preserving the anus or rectum. The authors elaborate on current status of sphincter-preserving strategies for low rectal cancer and the strategies in the era of immunotherapy, in order to provide references for treatment of low rectal cancer.

Objective:To analyze the clinical, genetic mutation characteristics, and treatment prognosis of type 2A hereditary hemochromatosis (HH) in China.Methods:Peripheral blood samples and clinical data of patients with primary iron overload were collected through the China Registry of Genetic/Metabolic Liver Disease from June 2015 to November 2023. HH-related genes were detected by Sanger sequencing. Clinical characteristics and gene mutation characteristics of HH patients carrying HJV gene mutations were analyzed.Results:Among the 37 cases with primary iron overload, ten cases (27.0%, 10/37) had detectable HJV gene mutations, which included four homozygous mutations, five compound heterozygous mutations, and one monoheterozygous mutation. p.Q6H and p.C321X (80.0%, 8/10) were the most common mutated sites. The average age of onset was 30.7±14.7 years. The age of diagnosis was 35.7±16.2 years, with male-to-female ratio of 7:3. Ferritin and transferrin saturation were (5 267±905) ng/ml, and 94.3%±1.2%, respectively. Magnetic resonance imaging showed iron overload in the liver, pancreas, and myocardium. Liver biopsy showed diffuse iron deposition within hepatocytes. All ten cases had elevated transaminases; one case (1/10, 10.0%) had liver cirrhosis; four cases (4/10, 40.0%) had heart failure and arrhythmia; five cases (5/10, 50.0%) had diabetes; six cases (6/10, 60.0%) had hypogonadism; six cases (6/10, 60.0%) had skin pigmentation; and six cases (6/10, 60.0%) had fatigue symptoms. All six cases underwent bloodletting therapy, and ferritin levels dropped to about 100 ng/ml. Two cases of oral administration of the iron chelator deferasirox did not meet the ferritin level standard, and one case died from acute heart failure following a confirmed diagnosis during hospitalization.Conclusion:The HJV gene may be one of the main pathogenic genes of HH in China. The p.Q6H and p.C321X mutations were one of the hotspot mutations. The onset age of HJV gene-related HH was between 20 and 30 years old, and their condition was severe. Therefore, early bloodletting treatment can have a favorable outcome.
