ObjectiveTo analyze the differences in color， odor and volatile components of Citri Reticulatae Pericarpium（CRP） before and after being stir-fried with Halloysitum Rubrum， and to explore the material basis of enhancing the effect of strengthening spleen after processing and the scientific connotation of decoction pieces processed with Halloysitum Rubrum as the auxiliary material. MethodsThe volatile components of the samples before and after processing were identified and relatively quantified by headspace gas chromatography-mass spectrometry（HS-GC-MS）， and the volatile components were analyzed by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. According to the principle of variable importance in the projection（VIP） value>1.5， volatile differential components before and after processing were screened. And combined with intelligent sensory technologies such as colorimeter and electronic nose， the chroma and odor information of CRP before and after being stir-fried with Halloysitum Rubrum were identified. Pearson correlation analysis was used to explore the correlation between volatile differential components and chroma values. ResultsA total of 112 volatile components were identified from CRP and CRP stir-fried with Halloysitum Rubrum， of which 84 were from CRP and 97 were from CRP stir-fried with Halloysitum Rubrum. And 7 differential components were selected， including α-pinene， β-myrcene， linalool， sabinene， ocimene isomer mixture， A-ocimene， and δ-elemene. After being processed with Halloysitum Rubrum， the brightness value（L^*）， yellow-blue value（b^*） and total chromatic value（E^*_ab） of CRP were decreased（P<0.01）， and red-green value（a^*） was increased（P<0.01）， the response values of S4， S5， S10 and S13 sensors were significantly increased（P<0.05）， and the response values of S3 and S8 sensors were significantly decreased（P<0.05）. Correlation analysis showed that α-pinene and β-myrcene were negatively correlated with L^* and E^*_ab， but positively correlated with a^*. Sabinene was positively correlated with L^* and E^*_ab. Linalool was positively correlated with L^* and E^*_ab， and negatively correlated with a^*. The ocimene isomer mixture was positively correlated with the L^*. ConclusionAfter being processed with Halloysitum Rubrum， the appearance color， odor and volatile components of CRP change significantly， and α-pinene， β-myrcene， sabinene， linalool and A-ocimene are the characteristic volatile components before and after processing， which can provide references for the quality evaluation and clinical application of CRP and its processed products.

Objective:To observe the clinical efficacy and safety of Jianpi Bushen Jiedu Prescription combined with 5-fluorouracil (5-FU)-based chemotherapy and targeted therapy for the treatment of advanced colorectal cancer patients with liver and kidney yin deficiency combined with spleen deficiency pattern.Methods:A randomized controlled trial was conducted. A total of 72 hospitalized patients with advanced colorectal cancer treated at the Department of Oncology, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from October 2022 to January 2024 were enrolled as study subjects. Using a random number table method, they were allocated into two groups, with 36 patients in each group. The control group received the mFOLFOX6/FOLFIRI combined with bevacizumab regimen, while the treatment group was administered additional oral Jianpi Bushen Jiedu Prescription on the basis of the control group. Two weeks was a cycle in both groups, with a total of 6 cycles of treatment. Serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), and carbohydrate antigen 724 (CA724) were detected using electrochemiluminescence; the Karnofsky Performance Status (KPS) scale was utilized to evaluate patients' functional status; vital signs were continuously monitored, and adverse reactions were recorded. The short-term efficacy and TCM syndrome efficacy of patients were evaluated.Results:The treatment group demonstrated higher objective response rate (ORR) [31.25% (10/32) vs. 21.88% (7/32), χ2=0.72] and disease control rate (DCR) [84.38% (27/32) vs. 71.88% (23/32), χ2=1.46] compared to the control group, without statistical significance ( P>0.05). Post-treatment levels of CEA [4.09 (3.31,8.57) μg/L vs. 10.07 (4.55,22.35) μg/L, Z=-2.10] and CA72-4 [4.54 (2.04,10.99) mU/L vs. 9.48 (4.34,18.95) mU/L, Z=-2.52] in the treatment group were significantly lower than those in the control group ( P<0.05). The total effective rate of TCM syndrome was significantly higher in the treatment group [78.13% (25/32)] compared with the control group [50.00% (16/32)], with statistical significance ( χ2=5.50, P=0.019). Post-treatment KPS scores in the treatment group [80.0 (80.0, 80.0) vs. 70.0 (62.5, 80.0), Z=-2.76] were significantly higher compared with the control group ( P<0.01). During the treatment period, the treatment group showed statistical significance compared with the control group in the incidence of hemoglobin decrease ( χ2=4.66), leukopenia decrease ( χ2=4.27), and peripheral neuropathy ( χ2=3.93), with statistical significance ( P<0.05). Conclusion:The addition of Jianpi Bushen Jiedu Prescription to 5-FU-based chemotherapy combined with targeted therapy demonstrates significant clinical benefits in advanced colorectal cancer patients, including reducing tumor marker levels, alleviating clinical symptoms, improving quality of life, and mitigating treatment-related toxicities, with a good safety.

Objective To explore the clinical application of ultrasound-guided transabdominal villus and amniocentesis in the prenatal diagnosis of thalassemia,and to find a suitable method for the prenatal diagnosis of thalassemia in Qinzhou.Methods A total of 531 high-risk pregnant women with severe or intermediate thalassemia during single pregnancy who were treated in the Department of Medical Genetics and Prenatal Diagnosis,Qinzhou Maternal and Child Health Hospital from March 2021 to April 2022 were selected for the study.According to different sampling methods,they were divided into control group(amniocentesis,n=415)and study group(transabdominal villus puncture,n=116).The success rate,complication rate of the two groups were compared.Results The success rate of puncture in the control group was 100％,2 cases were aborted within 2 weeks after surgery,17 cases were diagnosed with severe alpha-thalassemia,10 cases with severe β-thalassemia and 64 cases with intermediate thalassemia,48 cases with moderate and severe thalassemia induced labor.The success rate of puncture in the research group was 100％,10 cases were diagnosed with severe alpha-thalassemia,4 cases with severe β-thalassemia and 17 cases with intermediate thalassemia,and 26 cases with moderate severe thalassemia were induced labor.There was no significant difference in puncture success rate and abortion rate between the two methods(P>0.05).Conclusion Both methods are safe and effective.Transabdominal villus sampling can detect fetal thalassemia in early pregnancy,and it is worth promoting and applying in clinical practice.

Existing traditional Chinese medicine (TCM)-related databases are still insufficient in data standardization, integrity and precision, and need to be updated urgently. Herein, an Encyclopedia of Traditional Chinese Medicine version 2.0 (ETCM v2.0, http://www.tcmip.cn/ETCM2/front/#/) was constructed as the latest curated database hosting 48,442 TCM formulas recorded by ancient Chinese medical books, 9872 Chinese patent drugs, 2079 Chinese medicinal materials and 38,298 ingredients. To facilitate the mechanistic research and new drug discovery, we improved the target identification method based on a two-dimensional ligand similarity search module, which provides the confirmed and/or potential targets of each ingredient, as well as their binding activities. Importantly, five TCM formulas/Chinese patent drugs/herbs/ingredients with the highest Jaccard similarity scores to the submitted drugs are offered in ETCM v2.0, which may be of significance to identify prescriptions/herbs/ingredients with similar clinical efficacy, to summarize the rules of prescription use, and to find alternative drugs for endangered Chinese medicinal materials. Moreover, ETCM v2.0 provides an enhanced JavaScript-based network visualization tool for creating, modifying and exploring multi-scale biological networks. ETCM v2.0 may be a major data warehouse for the quality marker identification of TCMs, the TCM-derived drug discovery and repurposing, and the pharmacological mechanism investigation of TCMs against various human diseases.

ObjectiveTo investigate the tumor-suppressing effect of Shenqi Yiliu prescription combined with cisplatin in hepatoma H22-bearing mice based on the phosphatase and tensin homolog deleted on chromosome ten （PTEN）/phosphatidylinositol-3-kinase （PI3K）/protein kinase B （Akt） pathway. MethodH22-bearing mice were prepared and randomized into model group， cisplatin group， and cisplatin combined with high-， medium-， and low-dose Shenqi Yiliu prescription groups， with 10 mice in each group. Another 10 healthy mice were randomly selected as normal group. Shenqi Yiliu prescription was given by gavage with the high， medium， low dose of 54.06， 27.03， 13.515 g·kg^-1·d^-1， respectively， and cisplatin （2.5 mg·kg^-1） was administered by intraperitoneal injection， twice a week. Normal group and model group received normal saline. After 13 days of treatment， mice were killed and the tumor inhibition rate was calculated. The pathomorphological changes of tumor were observed based on hematoxylin-eosin （HE） staining， and enzyme-linked immunosorbent assay （ELISA） and immunofluorescence method were used to detect the content of cyclin-dependent kinase inhibitor 1A （p21） and cyclin-dependent kinase inhibitor 1B （p27） in tumor tissue of mice. The levels of PTEN， PI3K and phosphorylated protein kinase B （p-Akt） in tumor tissue were measured by Western blot. ResultCompared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription decreased tumor mass （P<0.05）， particularly the cisplatin in combination with the high-dose Shenqi Yiliu prescription. Necrosis of the tumor tissue was observed in each group， especially the cisplatin combined with high-dose Shenqi Yiliu prescription group. As compared with the model group， cisplatin alone and cisplatin in combination with the high-， medium-， and low-dose Shenqi Yiliu prescription raised the expression of p21， p27， and PTEN （P<0.05） and lowered the expression of PI3K and p-Akt （P<0.05）， particularly the cisplatin in combination with high-dose Shenqi Yiliu prescription. ConclusionShenqi Yiliu prescription may regulate the expression of key molecules in PTEN/PI3K/Akt signaling pathway， thereby upregulating the expression of downstream proliferation inhibitors p21 and p27， further suppressing the tumor in H22-bearing mice， and enhancing the effect of chemotherapy.

A 66-year-old male patient with malignant melanoma received combined treatments with apatinib (oral 250 mg once daily), temozolomide (oral 500 mg on day 1 and 400 mg/d on days 2-4), toripalimab(240 mg intravenous infusion on days 1 and 15). After 5 cycles (28 days as a cycle), the patient developed multiple rashes, which were not alleviated after reducing the dose of apatinib to 250 mg orally once every 3 days in the 6th treatment cycle. Laboratory tests showed that serum albumin was 28.5 g/L, total serum protein was 55.5 g/L, eosinophil percentage was 0.096, and venous potassium was 3.17 mmol/L. Erythroderma caused by combination of apatinib and toripalimab was considered, and the 2 drugs were stopped. The patient received the treatments of methylprednisolone, loratadine, diphenhydramine, triamcinolone acetonide and econazole nitrate cream and mupirocin ointment (external coating), and skin care. At the same time, symptomatic treatments such as protein supplement, diuresis, potassium supplement, and stomach protection were given. After 10 days of treatments, the rash subsided, and desquamation and itching were improved.
