Liumotang comes from the Yuan dynasty's Effective Prescription Handed Down for Generations of Physicians. It is composed of six medicinal materials： Arecae Semen， Aquilariae Lignum Resinatum， Aucklandiae Radix， Linderae Radix， Rhei Radix et Rhizoma， and Aurantii Fructus. It is a classical formula for treating abdominal pain due to Qi stagnation and constipation accompanied by heat. This study systematically collated the records of Liumotang in ancient medical books and modern clinical literature and conducted in-depth analysis and textual research on its formula source， main diseases， composition， dosage， medical books， container capacity， processing， preparation method， usage， drug basis， formula meaning， and other key information， so as to provide a powerful reference for the development and clinical application of compound preparations of the classical formula Liumotang. The results show that Liumotang was first seen in Effective Prescription Handed Down for Generations of Physicians， and many medical books of the past dynasties have imitated this. In terms of drug basis， the dried and mature seeds of the palm plant Areca catechu， resin-containing wood of the Daphneaceae plant Aquilaria sinensis， the dried roots of the Asteraceae plant woody Aucklandia lappa， the dried tuber root of the Lauraceae plant Lindera aggregata， the dried roots and rhizomes of the knotweed plant， R. palmatum， R.tangutikum， and R. officinale， and the dried and unripe fruits of the citrus genus C. aurantium and its cultivated varieties from the family Rutaceae were selected. In terms of dosage， through the textual research on bowls in the Ming and Qing dynasties， combined with the conversion of medicines and bowl capacity in the Qing dynasty， it was estimated that the dosage of each drug in the Yuan dynasty was 10.86 g. In the Ming and Qing dynasties， the dosage of drugs was mostly equal， but the dosage of drugs was somewhat different. In terms of processing， preparation method， and usage， in the medical books of the past dynasties， the processing of drugs has slightly changed， but raw drugs are used in all preparations. The preparation method and usage did not change much during the Yuan， Ming， and Qing dynasties， except for certain differences in dosage. In terms of syndrome， Liumotang was first used to treat abdominal pain due to Qi stagnation and constipation accompanied by heat. Medical books of the past dynasties often omit the symptoms of heat. In modern clinical practice， Liumotang is mainly used in the digestive system and urinary system diseases and is mostly used to treat constipation-predominant irritable bowel syndrome， biliary reflux gastritis， functional constipation， slow transit constipation， and other diseases， with no adverse reactions found yet. The above results provide a reliable scientific basis for the development and clinical treatment of Liumotang compound preparations.

OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized， translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform （from January 2024 to June 2024） in our hospital were selected as the intervention group， and 387 Tibetan outpatients before the implementation （from January 2023 to June 2023） were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services， while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions （ADR） set by the National Center for ADR Monitoring. Additionally， statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion （31.0%） of patients with good medication compliance and compliance scores [39.0 （37.0，42.0）] of patients in the intervention group were significantly better than control group [7.0%， 21.0（19.0， 23.0）]（ P＜0.05）. There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups （P＞0.05）. CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully； the service can effectively improve the medication compliance of Tibetan-language patients， but its effect on improving the medication safety of patients is limited.

Objective To analyze the effects of glucocorticoid stent implantation combined with nasal endoscopic surgery on nasal ventilation function and serum levels of eosinophil cationic protein(ECP),fibronectin(Fn)and aquaporin-1(AQP-1)in patients with chronic sinusitis with nasal polyp(CSwNP).Methods 60 patients with CSwNP from January 2022 to February 2023 were included in the study,and then they were divided into experimental group and control group,with 30 cases in each,using random number table method.The experimental group was treated with glucocorticoid stent implantation based on the original nasal endoscopic surgery,and the control group was treated with nasal endoscopic surgery,and both groups were treated until 12 weeks after surgery.The two groups of nasal symptoms,quality of life,nasal structure and ventilation function,serum levels of ECP,Fn,AQP-1,and adverse reactions were compared.Results Compared before the treatment,scores of nasal mucosal structure(Lund-Mackay scale),nasal symptom visual analogue scale(VAS)(including:nasal obstruction,runny nose,stuffy head,decreased sense of smell,nasal dryness/scab)and serum levels of ECP were decreased,distance from minimum nasal cross section to anterior nostril(DCAN)was shortened in two groups 12 weeks after treatment,and the experimental group was lower than the control group,the differences were statistically significant(P<0.05).Compared before the treatment,12 weeks after treatment,the nasal minimum cross-sectional area(NMCA),score of world health organization abbreviated quality of life(WHOQOL-100),nasal cavity volume(NCV),serum levels of Fn,AQP-1 were increased in two groups,and the experimental group was higher than the control group,the differences were statistically significant(P<0.05).During treatment,the incidence of adverse reactions was similar between the two groups(P>0.05).Conclusion Glucocorticoid stent implantation combined with nasal endoscopic surgery can control nasal symptoms in patients with CSwNP,improve nasal structure and ventilation function,regulate serum levels of ECP,Fn,AQP-1,and improve patients'quality of life.

Objective To explore the effect and mechanism of esculin on hepatocyte steatosis by inhibiting protein kinase RNA-like endoplasmic reticulum kinase(PERK)/eukaryotic translation initiation factor 2A(eIF2A)/activating transcription factor 4(ATF4)signaling pathway.Methods Human normal liver cell line HL-7702 was used to induce a fatty degeneration model of hepatocytes in vitro with 0.5mmol/L free fatty acid(FFA)(oleic acid∶palmitic acid=2∶1)and treated with 50μmol/L,200μmol/L esculin for 24h.After the cell samples were broken by ultrasound,the supernatant was collected and the contents of alanine transaminase(ALT),aspartate transaminase(AST),malondialdehyde(MDA),glutathione(GSH)and triacylglycerol(TG)were detected.Using Nile red fat fluorescence staining to detect intracellular lipid droplets;Quantitative reverse transcriptase-mediated polymerase chain reaction(qRT-PCR)was used to detect the transcription levels of genes related to intracellular lipid metabolism processes.Western blot(WB)was used to detect the protein expression levels of pro apoptotic factors Caspase-3 and Bax,as well as PERK/eIF2A/ATF4 signaling pathway related proteins and phosphorylation levels in cells.Results The results confirmed that treatments of 50μmol/L and 200μmol/L of esculin significantly decreased the levels of FFA induced MDA,ALT and AST in hepatocytes(P＜0.05),and significantly increased the levels of intracellular GSH(P＜0.05).WB results showed that esculin treatment could significantly reduce the protein expression levels of Caspase-3 and Bax(P＜0.01).The results of Nile red staining and TG content detection confirmed that esculin treatment could significantly reduce the accumulation of intracellular lipid droplets and TG content(P＜0.05).The results of qRT-PCR showed that the expression levels of PPARγ,FASN,Srebf1,Dgat2,Mvk and Acaca in hepatocytes were significantly decreased after esculin treatment(P＜0.05).In terms of mechanism,the phosphorylation levels of PERK,eIF2A and ATF4 in hepatocytes were significantly reduced by esculin treatment(P＜0.05).Conclusion Esculin could improve lipid accumulation in hepatocytes by regulating the PERK/eIF2A/ATF4 signalling pathway,which plays a positive role in maintaining the healthy state of hepatocytes.

Objective:To understand the current antiviral treatment status and various clinical types of treatment plans in Xiamen City so as to explore ways to improve and optimize the diagnosis and treatment standards for chronic hepatitis B.Methods:A cross-sectional survey method was used to study the antiviral treatment status and treatment plans for chronic hepatitis B patients who visited and were diagnosed in the Department of Infectious Diseases and Hepatology of all tertiary hospitals in Xiamen City at 0:00~23:59 on May 25, 2022.Results:A total of 665 cases were surveyed in this study, with an antiviral treatment rate of 81.2%(540/665). The antiviral treatment rate of patients who accorded with the current guidelines for antiviral treatment indications was 85.8%(507/591). The antiviral treatment rate for 362 outpatients was 72.9%(264/362). Among them, the antiviral treatment rates were 80.1%, 89.3%, and 25.0%(226/282, 25/28, 13/52), respectively, for patients diagnosed with chronic hepatitis B, hepatitis B cirrhosis, and hepatitis B surface antigen-carrying status. The treatment plan for all outpatient patients was mainly oral nucleos(t)ide analogues, accounting for 59.1%(214/362). The antiviral treatment rate for 303 inpatients was 91.1%(276/303). The various clinical types of antiviral therapy rates among all patients were 70%~95%. The antiviral treatment plan for inpatients was mainly based on pegylated interferon alpha treatment, accounting for 72.6%(220/303).Conclusion:Antiviral treatment for chronic hepatitis B in Xiamen City can still be strengthened to meet the current demand for expanding antiviral treatment indications. Antiviral treatment rates and various types of treatment plans differ between outpatients and inpatients; thus, further awareness and acceptance of the goal of improving antiviral therapy, especially in outpatients, and the possibility for a clinical cure based on pegylated interferon alpha treatment are needed to maximize the benefit to more patients.

Objective:To evaluate the therapeutic effects of Yufu ointment for acute radiation-induced skin injury. Methods:We enrolled a total of 104 patients with malignant tumors who developed acute skin injury of grade 2-3 during or after the first course of radiotherapy from June 2019 to February 2023. The observation group ( n=53) and control group ( n=51) received external application of Yufu ointment and Shirun Shaoshang ointment, respectively. We recorded the changes in the grade of skin injury and associated symptoms (such as pain, itching, and burning sensation) and healing speed and time for the two groups. Results:A total of 102 patients completed the study, with 53 cases in the observation group and 49 cases in the control group. The incidence rate of moisture skin lesions in the observation group was significantly lower than that in the control group (62.26% vs. 83.67%, P<0.05). The healing speed of moisture skin ulcerations was significantly faster in the observation group than in the control group (1.67 cm 2/d vs. 0.55 cm 2/d, P<0.05). The observation group had a significantly shorter time to skin injury healing than the control group (10.40 d vs. 14.41 d, P<0.05), significantly different for skin injury of grade 2 (10.21 d vs. 17.57 d, P<0.05) but not for skin injury of grades 2.5 and 3 ( P>0.05). Regarding clinical symptoms, both groups experienced significant reductions in pain and burning sensation scores after treatment ( P<0.05); the grade of itching was significantly decreased for the observation group ( P<0.05), but had no significant change for the control group after treatment ( P>0.05). Conclusions:Yufu ointment can significantly alleviate secondary damage for patients with acute radiation-induced skin injury, by accelerating the healing process and relieving symptoms such as pain, itching, and burning sensation with good tolerability, which deserves further promotion.

AIM: To investigate the effect of residual astigmatism on visual quality after phacoemulsification combined with regional refractive intraocular lens(IOL)implantation in patients with age-related cataract, and to evaluate the astigmatism inclusivity of regional refractive IOL.METHODS: Retrospective cohort study. The clinical data of 62 cases(73 eyes)of age-related cataract patients who underwent phacoemulsification combined with regional refractive IOL(Lentis Comfort LS-313 MF15)implantation from July 2020 to March 2022 at the ophthalmology department of our hospital were collected. They were grouped according to residual astigmatism at 6 mo postoperatively, taking 35 cases(40 eyes)with residual astigmatism of 0.75 D to 1.50 D as the experimental group, and 27 cases(33 eyes)with residual astigmatism ≤0.75 D as the control group. Visual acuity, defocus curves, objective visual acuity [wavefront aberrations, Strehl ratio(SR), modulation transfer functions(MTF)], subjective visual acuity(national eye institute visual function questionnaire-25), patients' satisfaction, and spectacle independence were compared between the two groups at 6 mo postoperatively.RESULTS:There was a difference in the preoperative astigmatism and the number of postoperative 6 mo residual astigmatism between the two groups(P<0.01). At 6 mo postoperatively, there was no difference in uncorrected distance, intermediate, and near visual acuity, objective visual quality, subjective visual quality, satisfaction, and spectacle independence between the two groups(P>0.05). The defocus curves showed that there was no difference in visual acuity between the two groups at all points in the +2.00 to -4.00 D defocus range of the additional spherical equivalent(P>0.05).CONCLUSION:Lentis Comfort LS-313 MF15 IOL was able to accommodate regular astigmatism of 1.50 D.

Objective To investigate the effect of residual corneal astigmatism on visual acuity after regional refrac-tive intraocular lens(IOL)implantation.Methods A retrospective cohort study was conducted.The medical records and follow-up data of 73 eyes of 57 cataract patients who underwent ultrasound emulsification cataract extraction combined with LENTIS Comfort LS-313 MF15 IOL implantation in the Ophthalmology Department of the Hebei General Hospital from June 2020 to March 2022 were collected.These patients were grouped according to postoperative residual corneal astigmatism:32 patients(40 eyes)with a residual corneal astigmatism of 0.75(exclusive)-1.50 D were taken as the experimental group,and 25 patients(33 eyes)with a residual corneal astigmatism ≤0.75 D were taken as the control group.The uncor-rected distance visual acuity(5 m),uncorrected intermediate visual acuity(80 cm),uncorrected near visual acuity(40 cm),out-of-focus curve,objective visual quality,subjective visual quality,satisfaction degree and lens removal rate of pa-tients in the two groups were recorded 6 months postoperatively.Results The postoperative uncorrected distance visual acuity(logMAR)was 0.10(0.00,0.22),the uncorrected intermediate visual acuity(logMAR)was 0.00(0.00,0.10),and the uncorrected near visual acuity(logMAR)was 0.20(0.10,0.30)and 0.20(0.10,0.20)in the experimental and control groups,with no statistically significant differences(all P＞0.05).The postoperative out-of-focus curves showed that the distance visual acuity of patients with additional spherical equivalent refraction ranged from+2.00 D to-4.00 D in the two groups had no statistically significant difference(all P＞0.05).There were statistically significant differences in to-tal aberration,coma aberration,modulation transfer function and Strehl ratio in the objective visual quality of patients after surgery(all P＜0.05),and there was no statistically significant difference in the total higher-order aberration,spherical ab-erration and cloverleaf aberration(all P＞0.05).There was no statistically significant difference in the subjective visual quality,satisfaction degree and lens removal rate in the two groups(all P＞0.05).Conclusion Residual corneal astig-matism of 0.75 D to 1.50 D after LENTIS Comfort LS-313 MF15 IOL implantation has no effect on higher-order aberration,spherical aberration,and cloverleaf aberration in subjective and objective visual quality,and has an impact on total aberra-tion,coma aberration,modulation transfer function and Strehl ratio in objective visual quality.

Objective To assess the effect of ultrasonic thyroid artificial intelligence(AI)-assisted diagnostic system(AI-assisted diagnostic system)for diagnosing medullary thyroid carcinoma(MTC)compared with different physicians and taken papillary thyroid carcinoma(PTC)as the controls.Methods Totally 63 MTC,70 PTC and 62 benign thyroid nodules confirmed by pathology were enrolled.AI-assisted diagnostic system was utilized to analyze thyroid nodules and identify the likelihood of malignancy,and the probability value threshold was set at ≥0.40.All thyroid nodules were retrospectively reviewed and categorized by 3 physicians(1 senior physician,1 attending physician and 1 junior physician)according to Chinese thyroid imaging reporting and data system(C-TIRADS).The efficacy of AI-assisted diagnostic system and physicians for diagnosing MTC and PTC were evaluated.Results AI-assisted diagnostic system showed lower sensitivity,specificity,positive predictive value,negative predictive value,accuracy,and area under the curve(AUC)for diagnosing MTC and PTC compared with physicians.Significant differences of AUC were found between senior physician and AI-assisted diagnostic system,as well as between attending physician and AI-assisted diagnostic system for diagnosing MTC and PTC(all P＜0.01),while no significant difference of AUC was between junior physicians and AI-assisted diagnostic system(both P＞0.05).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy and AUC for AI-assisted diagnostic system for diagnosing MTC were all lower than those for diagnosing PTC,but the AUC was not significantly different(P＞0.05).Conclusion Ultrasonic thyroid AI-assisted diagnostic system had relatively high value for diagnosing MTC.
