OBJECTIVE To provide technical support for improving recognition rate of adverse drug events (ADEs) related to traditional Chinese medicine (TCM) formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool (GTT) whitepaper, literature on adverse reactions to TCM, and expert review opinions, ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023, utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established, including thirty-two laboratory test indexes, thirteen clinical symptoms, and three antidotes. Among the 1 682 patients included, GTT identified 652 potential ADEs, 284 true positive ADEs,with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor, 278 cases of ADEs were finally confirmed, with an incidence rate of 16.53%, significantly higher than the number of spontaneously reported ADEs during the same period (0). The 278 cases of ADEs were mostly grade 1 (223 cases), mainly involving hepatobiliary system, gastrointestinal system, blood- lymphatic system, etc;a total of 219 types of TCMs are involved,and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos, Codonopsis pilosula, Atractylodes macrocephala, fried Glycyrrhiza uralensis, and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

The classic formula Mulisan is the 45th of the 93 formulas in the Catalogue of Ancient Classic Formulas (second batch) of Han medicine published by the National Administration of Traditional Chinese Medicine. It consists of Ostreae Concha, Astragali Radix, Ephedrae Radix et Rhizoma, and wheat, with the effect of replenishing qi and stopping sweating. It is a common formula in the clinical treatment with traditional Chinese medicine. This study analyzes the historical evolution, composition, dosage, original plants and their processing methods, decocting method, efficacy, indications, and modern clinical application of Mulisan by tracing, comparative analysis, and bibliometric methods. The results showed that Mulisan firstly appeared in the Pulse Classic written by WANG Shuhe in the Western Jin Dynasty. The formulation idea can be traced back to the Important Prescriptions Worth a Thousand Gold for Emergency in the Tang Dynasty. The herb composition, dosage, efficacy, and indications of Mulisan were first recorded in the Treatise on Diseases, Patterns, and formulas Related to Unification of the Three Etiologies in the Southern Song dynasty. In terms of original plants and their processing methods, Ostreae Concha is the shell of Ostrea rivularis, which should be calcined before use. Astragali Radix and Ephedrae Radix et Rhizoma are the dried roots of Astragalus membranaceus var. mongholicus and Ephedra sinica, respectively, the raw material of which should be used. Wheat is the dried mature fruit of T. aestivum, which can be used without processing, while the stir-fried fruit, being thin and deflated, demonstrates better effect. The composition of Mulisan is Ostreae Concha 8.26 g, Astragali Radix 8.26 g, Ephedrae Radix et Rhizoma 8.26 g, and wheat 7.92 g. The medicinal materials should be ground into coarse powder and decocted with 450 mL water to reach a volume of 240 mL, and the decoction should be taken warm. In modern clinical practice, Mulisan has a wide range of indications, including spontaneous sweating and night sweating caused by Yang deficiency or Qi deficiency. The clinical disease spectrum treated by Mulisan involves endocrine system diseases, neurological diseases, respiratory system diseases, and cancer. This formula plays a significant role in the treatment of internal medicine diseases in traditional Chinese medicine. This study aims to provide a scientific basis for the subsequent research, development, and clinical application of Mulisan.

Autologous blood patch pleurodesis (ABPP) was first proposed in 1987. Now it is mainly used to treat intractable pneumothorax and persistent air leakage after pneumonectomy, and also used to treat pneumothorax in children and other rare secondary pneumothorax. Persistent air leakage and pneumothorax of various causes are essentially alveolar pleural fistula. It can usually be treated by closed thoracic drainage, continuous negative pressure suction and surgery. Pleurodesis is a safe and effective alternative to surgery for patients who have failed conventional conservative treatment and can not receive operations. Compared with other pleurodesis adhesives, autologous blood (ABPP) is safer and more effective, and it is simple, painless, cheap and easy to be accepted by patients. But in the domestic and foreign researches in recent years, many details of ABPP treatment have not been standardized. For further research and popularization of ABPP, this article reviews the detailed regulations, efficacy and safety of this technology.

OBJECTIVE:
To observe the clinical effect of internal heat acupuncture therapy for knee osteoarthritis of early to middle stages, and explore its influence on cartilage thickness.
METHODS:
A total of 44 patients with knee osteoarthritis of early to middle stages were treated with internal heat acupuncture therapy at ashi points (most of them are located at the subpatellar fat pad, both sides of the patellar ligament, the tendon of the quadriceps and the attachment of the medial and lateral collateral ligaments), once a week, a total of 4 weeks of treatment. Before and after treatment, after 3 months of treatment completion (in the follow-up), the visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, frequency of 30-second chair stand test (30sCST), cartilage thickness of femoral intercondylar and knee joint ultrasound score were compared, and the clinical effect was evaluated.
RESULTS:
After treatment, the VAS、WOMAC and knee joint ultrasound scores were reduced (P<0.05), frequency of 30sCST was increased (P<0.05) compared with those before treatment; in the follow-up, the VAS、WOMAC scores were reduced (P<0.05), frequency of 30sCST and cartilage thickness of femoral intercondylar were increased (P<0.05) compared with those before treatment. After treatment, the total effective rate was 93.2% (41/44), in the follow-up, the total effective rate was 95.5% (42/44).
CONCLUSION
Internal heat acupuncture therapy is effective in the treatment of knee osteoarthritis of early to middle stages, could relieve the pain, improve the joint function, and delay cartilage degeneration and disease progression.

A dose reconstruction algorithm for electrionic portal imaging device(EPID)based on calibration and calculation is developed.The raw data of EPID in continuous acquisition mode are corrected for dark field and gain,and the gray level features of bright field are used to determine the field boundary.Subsequently,MU calibration,off-axis calibration and field size calibration are performed on the EPID data,and dose reconstruction is carried out based on the calibrated superimposed flux and the Monte Carlo model of the linac head.Nine cases of IMRT plans are selected for verification and measurement using EPID and MapCheck separately,and the passing rates between the two tools are compared under different gamma criteria(3%/3 mm and 2%/2 mm).For a planned case,the average passing rates of multiple cases verified by MapCheck under the two criteria were 99.02%±1.28%and 90.84%±4.49%,and the average passing rates of the EPID reconstruction models were 98.86%±1.19%and 91.39%±4.80%.Compared with MapCheck,the EPID reconstruction algorithm based on calibration and calculation has no significant difference in the passing rate of IMRT plan verification(P>0.05),which meets the clinical requirements of dose verification.

Although significant progress has been made in the development of novel targeted drugs for the treatment of acute myeloid leukemia(AML)in recent years,chemotherapy still remains the mainstay of treatment and the overall survival is poor in most patients.Here,we demonstrated the antileukemia activity of a novel small molecular compound NL101,which is formed through the modification on bendamustine with a suberanilohydroxamic acid(SAHA)radical.NL101 suppresses the proliferation of myeloid malignancy cells and primary AML cells.It induces DNA damage and caspase 3-mediated apoptosis.A genome-wide clustered regularly interspaced short palindromic repeats(CRISPR)library screen revealed that phosphatase and tensin homologous(PTEN)gene is critical for the regulation of cell survival upon NL101 treatment.The knockout or inhibition of PTEN significantly reduced NL101-induced apoptosis in AML and myelodysplastic syndrome(MDS)cells,accompanied by the activation of protein kinase B(AKT)signaling pathway.The inhibition of mammalian target of rapamycin(mTOR)by rapamycin enhanced the sensitivity of AML cells to NL101-induced cell death.These findings uncover PTEN protein expression as a major determinant of chemosensitivity to NL101 and provide a novel strategy to treat AML with the combination of NL101 and rapamycin.

AIM:To investigate the activation of Cl-channels by sodium taurocholate(NaTC)in mouse pan-creatic acinar cells.METHODS:The single isolated pancreatic acinar cells from FVB/N mice were prepared using colla-genase digestion method.Whole-cell patch clamp technique was performed to record the currents.Intracellular adenosine triphosphate(ATP)dependence of the channels was examined via eliminating ATP from the pipette solution.Anion per-meability of the channels was investigated with ion-exchange method.The pharmacological characteristics of the channels was confirmed by two Cl-channel blockers.The volume sensitivity of the channels was detected using 47%hypertonic bathing solution.Extracellular Ca2+dependence of activating the channels was examined through eliminating Ca2+from the bathing solution.Intracellular reactive oxygen species(ROS)level was detected by an oxidation-sensitive fluorescent probe,2',7'-dichlorofluorescin diacetate.The experiment was repeated 6 times in each group.RESULTS:Extracellular application of 5 mmol/L sodium taurocholate induced a Cl-current,exhibiting the properties of outward-rectification,a se-lectivity sequence of I->Br-≥Cl->gluconate-and intracellularATP dependence(P<0.01).The currents were inhibited by chloride channel blocker 4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid disodium salt hydrate(DIDS)and tamoxifen and by 47%hypertonicity stimulation(P<0.01).When ROS production was scavenged by N-acetyl-L-cysteine,the sodi-um taurocholate-induced Cl-currents were unaffected.The effect of sodium taurocholate on ROS production did not alter with the treatment with DIDS.Sodium taurocholate failed to induce Cl-currents when Ca2+was absent in extracellular bath-ing solution(P>0.05).CONCLUSION:Sodium taurocholate activates Cl-channels in mouse pancreatic acinar cells,which is dependent on extracellular Ca2+but not ROS pathway.

Objective:To investigate the clinical features, diagnosis and treatment of oblique vaginal septum syndrome (OVSS).Methods:The clinical data of 80 patients with OVSS admitted to The Second Hospital of Hebei Medical University from July 2005 to July 2023 were retrospectively analyzed. According to the classification system of OVSS proposed by Female Genital Anomalies Study Group, Chinese Obstetricians and Gynecologists Association in 2021, the patients were divided into four groups. The clinical manifestations, accompanied urinary system abnormalities, diagnosis and treatment methods and treatment outcomes were observed.Results:According to the above classification system, among the 80 patients with OVSS, 35 patients (44%, 35/80) were categorized as type Ⅰ, 33 patients (41%, 33/80) were categorized as type Ⅱ, 2 patients (3%, 2/80) were categorized as type Ⅲ and 10 patients (13%, 10/80) were categorized as type Ⅳ. The main onset symptom of patients was periodic abdominal pain (70%, 56/80), vaginal bleeding (20%, 16/80), dysuria or fecal impaction (15%, 12/80), vaginal mucopurulent discharge (10%, 8/80). The morbidity of combined urinary system abnormalities was 88% (70/80), and the most common urinary system abnormality was ipsilateral renal agenesis (81%, 65/80). Bilateral kidneys were normal in 13% (10/80) patients, and 6% (5/80) were combined with other urinary system abnormalities. A total of 74 patients underwent vaginal oblique septectomy or septum excision. Five of the 10 patients with type Ⅳ underwent hysterectomy on the cervical atresia side, 4 patients received hysteroscopy combined with cervicoplasty+oblique septotomy or septum excision, and one patient selected delayed menstruation. Two patients underwent laparoscopic resection of the dysplasia kidney and ectopic ureter which opening to the vagina. Eleven patients with endometriosis cyst, hydrosalpinx or empyema underwent laparoscopic surgery.Conclusions:The main symptom of type Ⅰ and Ⅳ patients is abdominal pain, while the main symptom of type Ⅱ and Ⅲ patients is bleeding. Magnetic resonance imaging (MRI) has advantages in the evaluation of complex OVSS, and MRI is recommended before operation to exclude other axial reproductive tract dysplasia and complex urinary system dysplasia. If there is leakage of urine, vaginal discharge or complex deformity, it is necessary to multidisciplinary discussion and formulate a reasonable surgical plan. The first treatment is related to the prognosis of patients especially children, and should be highly valued.
