ObjectiveTo improve the quality standard of Yuanhu Zhitong oral liquid in order to strengthen the quality control of this oral liquid. MethodThin layer chromatography（TLC） was used for the qualitative identification of Corydalis Rhizoma and Angelicae Dahuricae Radix in Yuanhu Zhitong oral liquid by taking tetrahydropalmatine， corydaline reference substances and Corydalis Rhizoma reference medicinal materials as reference， and cyclohexane-trichloromethane-methanol（5∶3∶0.5） as developing solvent， Corydalis Rhizoma was identified using GF254 glass thin layer plate under ultraviolet light（365 nm）. And taking petroleum ether（60-90 ℃） -ether-formic acid（10∶10∶1） as developing solvent， Angelicae Dahuricae Radix was identified using a silica gel G TLC plate under ultraviolet light（305 nm）. High performance liquid chromatography（HPLC） was performed on a Waters XSelect HSS T3 column（4.6 mm×250 mm， 5 μm） with acetonitrile（A）-0.1% glacial acetic acid solution（adjusted pH to 6.1 by triethylamine）（B） as the mobile phase for gradient elution（0-10 min， 20%-30%A； 10-25 min， 30%-40%A； 25-40 min， 40%-50%A； 40-60 min， 50%-60%A）， the detection wavelength was set at 280 nm， then the fingerprint of Yuanhu Zhitong oral liquid was established， and the contents of tetrahydropalmatine and corydaline were determined. ResultIn the thin layer chromatograms， the corresponding spots of Yuanhu Zhitong oral liquid， the reference substances and reference medicinal materials were clear， with good separation and strong specificity. A total of 12 common peaks were identified in 10 batches of Yuanhu Zhitong oral liquid samples， and the peaks of berberine hydrochloride， dehydrocorydaline， glaucine， tetrahydropalmatine and corydaline. The similarities between the 10 batches of samples and the control fingerprint were all >0.90. The results of determination showed that the concentrations of corydaline and tetrahydropalmatine had good linearity with paek area in the range of 0.038 6-0.193 0， 0.034 0-0.170 0 g·L^-1， respectively. The methodological investigation was qualified， and the contents of corydaline and tetrahydropalmatine in 10 batches of Yuanhu Zhitong oral liquid samples were 0.077 5-0.142 9、0.126 1-0.178 2 g·L^-1， respectively. ConclusionThe established TLC， fingerprint and determination are simple， specific and reproducible， which can be used to improve the quality control standard of Yuanhu Zhitong oral liquid.

ObjectiveTo elucidate the underlying mechanism of the efficacy of Levo-tetrahydropalmatine （l-THP） in alleviating chronic pain and identify the key metabolites and metabolic pathways for l-THP regulation. MethodA classical chronic constrictive injury （CCI） model was built in rats’ bodies， and the pain intensity was evaluated by detecting the mechanical withdrawal threshold. On the sixth day after surgery， oral administration of l-THP （64 mg·kg^-1） and positive control drug pregabalin （Pre， 30 mg·kg^-1） was performed on rats. After the last administration following consecutive five times of administration， ipsilateral spinal cord tissues were collected for widely-targeted metabonomics， with eight rats in each group. Differential metabolites （DEMs） were identified according to the standard of VIP>1.0 and P<0.05， and functional enrichment and interaction analyses of the Kyoto Encyclopedia of Genes and Genomes （KEGG） were performed to obtain the key metabolites and metabolic pathways associated with the analgesic effects of l-THP. ResultIn behavioral science， administration of both l-THP and Pre significantly improved mechanical hyperalgesia in CCI rats （P<0.01）， thus mitigating pain. Metabonomic analysis results revealed that l-THP administration corrected the aberrant metabolic profile in the spinal cord of CCI rats. Meanwhile， 53 DEMs were called back， including several classical pain biomarkers such as sphingosine-1-phosphate （S1P）， cyclic adenosine monophosphate （cAMP）， acetylcholine， and glutamate. Functional enrichment analysis of the DEMs indicated the involvement of metabolic pathways such as ferroptosis， autophagy， neuroactive ligand-receptor interactions， phospholipase D and cAMP-related signaling pathways， glutathione metabolism， and cofactor biosynthesis in mediating the effects of l-THP on the metabolic profile of the spinal cord. Further analyses on the relative metabolite abundance and metabolic pathways indicated that by significantly decreasing the relative levels of glutamate （P<0.01） and glycine （P<0.01） in the spinal cord， l-THP can promote the synthesis of reduced glutathione （GSH） and increase the ratio of reduced/oxidized GSH （P<0.05）. Additionally， it can relieve oxidative stress in the spinal cord of CCI rats and significantly reduce the acetyl-CoA level （P<0.01） to finally inhibit ferroptosis occurrence. Conclusionl-THP may exert analgesic effects by regulating multiple metabolic pathways including GSH metabolism， ferroptosis， cofactor biosynthesis， and amino acid synthesis to correct the aberrant metabolic profile in the spinal cord of CCI rats. Ferroptosis and GSH metabolism may be the key pathways for l-THP regulation， with glutamate， glycine， glutathione， and acetyl-CoA as the key metabolites.

OBJECTIVE To analyze the pharmaceutical service process in a fracture patient complicated by fat embolism syndrome （FES） following postoperative fracture， aiming to provide a reference for clinical treatment and pharmaceutical service for similar patients. METHODS Clinical pharmacist participated in the entire treatment process of a patient with FES following postoperative fracture. Based on the patient’s clinical manifestations and test results， literature was reviewed to assist clinical physicians in formulating the therapeutic regimen of glucocorticoids. For the drug-related adverse reactions of renal function impairment and reduced platelet count that occurred during the treatment， suspicious drugs were analyzed and disposed of accordingly. RESULTS The clinical pharmacist recommended Hydrocortisone sodium succinate for injection （100 mg， q8 h， ivgtt， for about one week followed by a gradual dose reduction） for treating FES. The Vancomycin hydrochloride for injection used in this case was assessed as “very probably” associated with the adverse drug reactions of renal function impairment and thrombocytopenia. The clinical physician adopted the pharmacist’s medication recommendations， and the patient’s condition stabilized after treatment， with improvement in adverse reactions， and was discharged from the hospital. CONCLUSIONS The use of glucocorticoids in treating FES has a definite therapeutic efficacy. Clinical pharmacists should individualize the medication plan based on the patient’s pathological state and distinguish it from postoperative sepsis. Meanwhile， drug-induced adverse reactions in the kidney and blood system should be closely monitored.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome types and influencing factors of protein-energy wasting （PEW） in chronic kidney disease （CKD） undergoing maintenance hemodialysis （MHD）. MethodsAccording to diagnostic criteria， 164 patients with MHD were divided into PEW group and non-PEW group. The clinical data of all patients were collected， including general information such as gender， age， height and weight， disease characteristics such as course， cormobidity， and haemodialysis duration， laboratory indicators such as blood routine， liver function， renal function， electrolyte， blood lipid， grip strength， and the four examinations. Logistic regression analysis was used to find the influencing factors of PEW by taking the clinical indicators with significant differences between the two groups （P＜0.05） as the independent variables， diagnosis of PEW as the dependent variable， and normal values as the reference. ResultsOut of 164 patients with MHD， there were 96 （58.5%） cases in PEW group and 68 cases （41.5%） in non-PEW group. Compared to the non-PEW group，PEW group had increased age， ratios of bedrest， deep vein preservation， edema， and low grip strength， percentages of comorbidities type 2 diabetes， cardiovascular and cerebrovascular diseases，infections and anemia， and levels of alanine aminotransferase and permine amin aminotransferase， as well as decreased body mass index， self-care ratio，internal arteriovenous fistula， red blood cell count， hemoglobin， serum total protein， serum albumin levels （P＜0.05）. The PEW group had significantly higher frequency of poor appetite and digestion， abdominal distension， fear of cold and preference of warmth， weak breathing and fatigue， poor appetite， oliguria， nausea and vomiting than non-PEW group （P＜0.05）. The incidence of both yin and yang deficiency syndrome and damp-turbidity syndrome were significantly higher in the PEW group than the non-PEW group， while that of liver-kidney yin deficiency syndrome and stirring of wind syndrome were lower （P＜0.05）. Logistic regression analysis showed that low BMI （＜22 kg/m²）， inability to take care of oneself， low grip strength，low serum albumin （＜38 g/L）， infection， older age， fear of cold and cold limbs，and poor appetite were the risk factors of PEW in patients undergoing MHD （P＜0.05）. ConclusionThe root syndrome of MHD-PEW patients is both yin and yang deficiency， concurrent with damp-turbidity syndrome. Low BMI， low serum albumin， infection and older age may be the influencing factors of PEW in patients undergoing MHD.

【Objective】 To analyze the distribution of unexpected antibodies in tumor patients retrospectively and explore the clinical significance. 【Methods】 Unexpected antibody screening was performed on inpatients with blood preparation and blood transfusion in our hospital from January 2004 to December 2022, with 1 176 cases tested positive, and the types of unexpected antibodies and distribution characteristics were statistically analyzed. 【Results】 Unexpected antibodies were screened in 1 176 cases, with the positive rate at 1.05% (1 176/111 483).

Among the 1 176 cases, gastrointestinal tumors accounted for 27.99% (329/1 176), gynecological tumors accounted for 24.84% (292/1 176), respiratory tumors accounted for 16.67% (196/1 176) . 【Conclusion】 The influencing factors of unexpected antibodies in tumor patients were disease type, blood transfusion history and blood type. Therefore, it is necessary for clinical departments to carry out unexpected antibody screening and perform Rh blood type matched transfusion for tumor patients to avoid alloantibody production.

ObjectiveAlmond， which is bitter in taste， contains traces of toxic substances. For the sake of the safety of prescriptions containing this medicinal material， the processing method of "soaking in boiling water" was selected. Moreover， through literature research and network pharmacology， the characteristic index of this medicinal material was determined. On this basis， a method was established for the determination of amygdalin in Qingfei Paidu Granules （QFPD） and the transfer rate of it in the processing of this prescription was monitored， aiming at improving the quality control system of QFPD. MethodThe high performance liquid chromatography conditions are as follows： YMC Triart C₁₈ column （4.6 mm × 150 mm， 5 µm）， mobile phase of methanol-water with flow of 1.0 mL·min^-1， column temperature of 35 ℃， and detection wavelength of 210 nm. ResultThe linear curve fitted well and the average recovery of amygdalin was 97.74% with RSD of 4.3%. The transfer rates of amygdalin from the medicinal material to the extract， from extract to concentrate， and from concentrate to granules were investigated with this method. The result showed that the average transfer rate from the medicinal material to the granules was （60±3.91）%. The comparison of transfer rate between the processes suggesting that the extraction of the medicinal material might be the key part influencing the prescription preparation. ConclusionThe method is simple， sensitive， reproducible， stable， and accurate， and the index is reasonable. Thus， the method can be used for the quality control of QFPD and determination of transfer rate of components in the preparation of QFPD. This study further improves the quality control standard of almond in QFPD， which can serve as a reference for the clinical application of QFPD.

Over the past decade, traditional Chinese medicine (TCM) has widely embraced systems biology and its various data integration approaches to promote its modernization. Thus, integrative pharmacology-based traditional Chinese medicine (TCMIP) was proposed as a paradigm shift in TCM. This review focuses on the presentation of this novel concept and the main research contents, methodologies and applications of TCMIP. First, TCMIP is an interdisciplinary science that can establish qualitative and quantitative pharmacokinetics-pharmacodynamics (PK-PD) correlations through the integration of knowledge from multiple disciplines and techniques and from different PK-PD processes

Objective: To investigate the maternal and neonatal outcomes of fetal meconium peritonitis (FMP) cases with different ultrasonic manifestations. Methods: The clinical data of 31 pregnant women with FMP diagnosed by prenatal ultrasound and confirmed by postnatal imaging examination in Guangzhou Women and Children's Medical Center from January 2011 to December 2018 were analyzed retrospectively. According to the last prenatal ultrasonographic findings, the 31 cases were classified into the following grades: grade 0 (three cases), grade 1 (20 cases, grade 1A: nine cases, grade 1B: three cases, grade 1C: eight cases), grade 2 (seven cases) and grade 3 (one case). All neonates were also divided into two groups: the operation group (19 cases) and conservative treatment group (12 cases) based on whether or not underwent surgery. Statistical methods were independent sample t-test and Chi-square test. Results: (1) The gestational ages at the first diagnosis of FMP and birth of the operation group were both lower than those of the conservative treatment group [(29.9±4.5) vs (38.2±1.0) weeks, t=-6.202; (36.2±2.7) vs (38.2± 1.0) weeks, t=-2.426; both P<0.05]. (2) The operation rates in cases of grade 0, 1, 2 and 3 groups were 0/3, 55%(11/20), 7/7 and 1/1, respectively (χ²=10.136, P=0.017). However, the operation rates in grade 1A, 1B and 1C groups were 7/9, 1/3 and 3/8, respectively (χ²=3.446, P=0.179). Conclusions The rate of operation of FMP newborn was related to the gestational age of the first prenatal ultrasound diagnosis of FMP and the ultrasonic grade. The different grades of prenatal ultrasound in FMP cases can provide important information for guiding perinatal treatment.

Pancreatic cancer has poor prognosis and lymph node metastasis is a poor prognostic factor in patients with resectable pancreatic cancer. The metastatic prevalence of para-aortic lymph node (PALN) ranges from 9.1% to 26.5% and it is listed as the distant metastatic group in pancreatic cancer. Nevertheless, it is controversial whether PALN metastasis is the contraindication of surgery in resectable pancreatic cancer for the shortage of level Ⅰ evidence.This study concluded that PALN metastasis indicated poor prognosis in patients with pancreatic cancer, but some patients with PALN metastases could benefit from surgery and their survival could be much improved after the combination of surgery and adjuvant therapy. Therefore, it is not wise to refuse surgery for all pancreatic cancer patients with PALN metastasis and the clinicians can cautiously choose the patients to do surgery. Besides, there are mainly retrospective studies rather than prospective and multicenter studies to explore the prognosis of pancreatic cancer patients with PALN metastasis. Thus, more prospective and multicenter studies are needed to decide whether PALN metastasis is an independent prognostic factor in patients with resectable pancreatic cancer.
