Yuejuwan is a classic formula widely used by doctors to relieve liver and depression， with precise clinical efficacy in traditional Chinese medicine （TCM）. The authors used bibliometric methods to collect and collate 495 ancient data related to Yuejuwan， and 105 valid data were screened out， involving 68 ancient Chinese medical books. After systematic verification of the origin of the formula of Yuejuwan， the main treatment symptoms， the principle of the formula， the composition of the drug， the dosage， the preparation method， the decoction method， and other information， the results showed that Yuejuwan originated from the Danxi Xinfa （《丹溪心法》） of the Yuan Dynasty by ZHU Zhenheng， and it is composed of five medicines， namely Atractylodis Rhizoma， Cyperi Rhizom， Chuanxiong Rhizoma， Massa Medicata Fermentata， and Gardeniae Fructus. In terms of drug base， Atractylodis Rhizoma， Cyperi Rhizom， Chuanxiong Rhizoma， and Gardeniae Fructus are in line with the records in the 2020 edition of Chinese Pharmacopoeia， and Massa Medicata Fermentata is used. The preparation method is as follows： Massa Medicata Fermentata and Gardeniae Fructus are fried， and Cyperi Rhizoma is roasted in vinegar. Chuanxiong Rhizoma is used in the raw form， and Atractylodis Rhizoma is prepared with rice swill. The formula can regulate Qi and relieve depression and broaden the middle and remove fullness. It is clinically used for the treatment of six types of depression syndromes， chest and diaphragm plumpness， abdominal distension and leg acid， acid swallowing and vomiting， eating and drinking disharmony， toothache， mouth and tongue sores， and other diseases. The most used dosage of the formula in the ancient records through the ages is converted into the modern dosage， namely 3.05 g Atractylodis Rhizoma， 3.05 g Cyperi Rhizoma， 3.05 g Chuanxiong Rhizoma， 3.05 g Massa Medicata Fermentata， and 3.05 g Gardeniae Fructus， and the daily dosage is 15.25 g. The converted dosage is similar to that recorded in the 2020 edition of the Chinese Pharmacopoeia. The formula is in pill form， and medicine should be taken with lukewarm boiled water after the meal.

Background/Aims: Endoscopic wound suturing is an important factor that affects the ability to remove large and full-thickness lesions during endoscopic resection. We aimed to evaluate the effect of a traction metal clip with a fishhook-like device on wound sutures after endoscopic resection. Methods: From July 2020 to April 2021, patients who met the enrollment criteria were treated with a fishhook-like device during the operation to suture the postoperative wound (group A). Patients with similar conditions and similar size wounds who were treated with a “purse-string suture” to suture the wounds were retrospectively analyzed as the control group (group B). Difference in the suture rate, adverse events, time required for suturing, and number of metal clips were compared between the two groups. Results: The time required for suturing was 7.72±0.51 minutes in group A and 11.50±0.91 minutes in group B. This difference was statistically significant (F=13.071, p=0.001). The number of metal clamps used in group A averaged 8.1 pieces/case, and the number of metal clamps used in group B averaged 7.3 pieces/case. This difference was not statistically significant (F=0.971, p>0.05). Conclusions The traction metal clip with the fishhook-like device is ingeniously designed and easy to operate. It has a good suture effect on the wound after endoscopic submucosal dissection and effectively prevents postoperative adverse events.

Objective:To establish a classification model for rapid identification of hypervirulent subtype ST17 clones of Group B Streptococcus (GBS) using matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS).Methods:In a retrospective study, 235 strains of GBS strains were selected from multiple centers in China during 2015-2018. For model generation,45 strains of ST17 and 50 strains of non-ST17 (20 ST19, 15 ST12 and 15 ST10 strains) were enrolled as the modeling group. The remaining 90 main ST strains (40 ST17, 16 ST10, 17 ST12 and 17 ST19) were served as validation group. 50 GBS strains classified as other minor ST subtypes were regarded as taxonomic groups. MS spectra were collected by Bruker mass spectrometry, and then loaded for model generation and verification, and screening of differential peptide peaks by genetic algorithm (GA) and model verification on ClinProTools 3.0 software.Results:The recognition rate for ST17-GA model were 99.4% with cross validation value of 96.9%. Among the ten differential peptide peaks for the classification model, the weights of both two main peptide peaks m/z 2 956 and m/z 5 912 were greater than 1, while the weights of the all other eight peptide peaks were less than 0.5. Model validation showed only one of the ST17 was misjudged as non-ST17 strain, resulting in diagnostic accuracy of 98.9%, sensitivity of 97.5% and specificity of 100%, positive predictive value of 100% and negative predictive value of 98.0%, respectively. For other sporadic STs, 42.0% (21/50) of them were misdiagnosed as ST17 subtype.Conclusion:A MALDI-TOF MS classification model for hypervirulent subtype of ST17 GBS strains has been successfully established with good diagnostic efficacy.

Objective To investigate the clinical characteristics,antibiotic susceptibilities and serotypes of Group B Streptococcus(GBS)isolated from neonatal meningitis to provide references for the prevention and treatment of neonatal GBS meningitis. Methods From June 2013 to June 2016,we surveyed the GBS strains iso-lated from purulent meningitis of < 90 days infants from Guangzhou Women and Children′s Medical Center. The GBS isolates were identified and the minimum inhibitory concentration of the antibiotics was determined by Vitek 2 Compact automatic bacterial identification system.GBS serotyping was performed using Strep-B-Latex?rapid latex agglutination test kit. Results A total of 46 cases of neonatal GBS meningitis,15 cases of early-onset infection and 31 cases of late-onset infection were diagnosed. 78.3% of GBS meningitis with varying degrees of complica-tions.Among 41 survivors with 3~24 months follow-up,50% of the early-onset and 44.8% of the late-onset GBS meningitis with varying degrees of neurological sequelae.Four capsular types were identified among the 46 isolates, serotype-Ⅲwas the most prevalent(73.9%),followed by Ib(19.6%),V(4.3%)and Ia(2.2%).All the isolates were susceptible to penicillins,cephalosporins,linezolid and vancomycin. Conclusion The highly pathogenic serotype-Ⅲ was the predominant serotype among neonatal GBS meningitis in Guangzhou,Therefore,it is neces-sary to strengthen the epidemiological surveillance of GBS invasive infection and the effective implementation of pre-ventive measures.

Group B streptococcus ( GBS) is the most common cause of neonatal invasive infections in western countries , leading to severe pneumonia , sepsis and meningitis with high mortality and morbidity . Neonatal GBS infections are mainly transmitted from mother to baby .Since the end of 1990 s, prevention strategies of antenatal GBS screening and intrapartum antibiotic prophylaxis ( IAP) have been implemented by European and American area , decreasing the incidence of neonatal GBS disease significantly .The harm of GBS to neonates has been recognized and valued in recent years in China , but the authorized prevention measures are still lacking.Efficacy of IAP-based prevention depends on the accuracy of GBS screening results during pregnancy .Here, the GBS prevention guideline or consensus recommended by European and American CDC, including the screening strategies , detection methods, sample collection, storage and transportation were interpreted .
