ObjectiveTo establish the fingerprints of 15 batches of Hengzhi Kechuan capsules, to quantitatively analyze 10 index components, and to evaluate the quality uniformity of samples from different batches. MethodsThe fingerprints and quantitative analysis of Hengzhi Kechuan capsules were established by a combination method of high performance liquid chromatography coupled with diode array detector and charged aerosol detector(HPLC-DAD-CAD), adenosine, guanosine, vanillic acid, safflomin A, agarotetrol, naringin, hesperidin, militarine, ginsenoside Rb1, and glycyrrhizic acid were selected as quality attribute indexes. A total of 15 batches of Hengzhi Kechuan capsules from 2022 to 2024(3 boxes per batch) were qualitatively and quantitatively analyzed, and the quality uniformity level of the manufacturers was characterized by parameters of intra-batch consistency(PA) and inter-batch consistency(PB). The homogeneity and difference of quality attribute indexes of samples from different years were analyzed by heatmap clustering analysis. ResultsHPLC fingerprints and quantitative method of Hengzhi Kechuan capsules were established, and the methods could be used for qualitative and quantitative analysis of this preparation, which was found to be stable and reliable by method validation. The similarity of fingerprints of 15 batches of samples was 0.887-0.975, a total of 13 common peaks were calibrated, and 10 common peaks were designated, all of which were quality attribute index components. The results of quantitative analysis showed that the contents of the above 10 ingredients in the samples were 0.038-0.078, 0.115-0.251, 0.007-0.018, 0.291-0.673, 0.122-0.257, 0.887-1.905, 1.841-3.364, 1.412-2.450, 2.207-3.112, 0.650-1.161, respectively. And the contents of ginsenoside Rb1 and glycyrrhizic acid met the limit requirements in the 2020 edition of Chinese Pharmacopoeia. For the samples from 15 batches, the PA values of the 10 index components were all <10%, indicating good intra-batch homogeneity, and the PB values ranged from 33.86% to 92.97%, suggesting that the inter-batch homogeneity was poor. Heatmap clustering analysis showed that the samples from different years were clustered into separate categories, and adenosine, guanosine, safflomin A, naringin, hesperidin and agarotetrol were the main differential components. ConclusionThe intra-annual quality uniformity of Hengzhi Kechuan capsules is good and the inter-annual quality uniformity is insufficient, which may be related to the quality difference of Pinellinae Rhizoma Praeparatum, Carthami Flos, Citri Sarcodactylis Fructus, Citri Reticulatae Pericarpium, Aquilariae Lignum Resinatum, Citri Fructus, etc. In this study, the fingerprint and multi-indicator determination method of Hengzhi Kechuan capsules was established, which can be used for more accurate and efficient quality control and standardization enhancement.

ObjectiveTo explore quality difference factors of Perillae Caulis based on the contents of multiple chemical components and comprehensively evaluate the quality. MethodsA total of 32 batches of Perillae Caulis samples were collected from 12 producing areas such as Hebei, Anhui and Guangdong, and their diameter range, epidermis color and producing areas were recorded. Total flavonoids, total phenols, volatile oils, 5 active components and 84 volatile components in 32 batches of samples were quantitatively or semi-quantitatively determined by colorimetry, ultra performance liquid chromatography-photodiode array detector(UPLC-PDA) and gas chromatography-mass spectrometry(GC-MS). Then the differences between the contents of these components were analyzed by principal component analysis(PCA) and non-parametric test. According to the weights of the index components determined by PCA model, entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) model was constructed to evaluate the quality of Perillae Caulis with different characters and origins. ResultsThere were significant differences in the composition of Perillae Caulis with different diameters, epidermis colors and producing areas, and 9 differential components were screened out, including 6 index constituents(total flavonoids, total phenols, caffeic acid, scutellarin, rosmarinic acid and luteolin) and 3 volatile components(caryophyllene oxide, (-)-humulene epoxide Ⅱ, 14-hydroxycaryophyllene), of which 6 index constituents were higher in samples with small diameter, purple-brown epidermis and southern origin, while the contents of 3 volatile components were higher in samples with large diameter, dark-brown epidermis and northern origin. A significant difference was shown in the model scores of different diameters, epidermis colors and origins(P<0.05), and the scores of Perillae Caulis with small diameter and purple-brown epidermis from southern area, especially Guangdong, had a high score. ConclusionThere are significant differences in the composition and content of chemical constituents between different diameters, epidermal colors and production areas of Perillae Caulis, samples showing small diameter, owing purple-brown epidermis, and originating from Guangdong were of higher-quality due to their higher content of 8 key indices.

Objective Based on the epidemic situation of hepatitis B and liver cancer patients in Nantong from 2019 to 2022, to analyze the trend of hepatitis B virus DNA (HBV-DNA) changes and provide theoretical basis for the prevention and treatment of hepatitis B and liver cancer. Methods The data of patients with hepatitis B and liver cancer in Nantong Cancer Hospital were collected, and the general data, the time of infection with hepatitis B and the results of quantitative HBV-DNA test were statistically analyzed. Results A total of 487 patients with hepatitis B and liver cancer were collected, including 395 males and 92 females. Among them, patients aged 51-60 were the most common, accounting for 28.34%, followed by those aged 41-50 and 61-70, accounting for 23.00% and 21.56% respectively. In addition to 84 patients with unknown infection time, most of the patients with hepatitis B infection time distributed in 11 to 20 years, followed by 21 to 30 years and 1 to 10 years. Except for 126 patients with unknown levels of HBV DNA, the positive rate of HBV DNA in 361 patients was 64.82%. Between 2019 and 2022, except for patients with unknown levels of HBV-DNA, the proportion of patients with HBV-DNA<500 copies/mL showed an upward trend, while the proportion of patients with HBV-DNA (103-106) copies/mL showed a downward trend. Conclusion Sex and the time of infection with hepatitis B are high risk factors for hepatitis B liver cancer. Most patients with liver cancer are positive for HBV-DNA, which needs to be tested regularly to guide antiviral treatment.

Objective:To investigate the current state of missed nursing care during labor, explore the reasons why nursing care was missed, and examine the influencing factors of missed nursing care.Methods:Data were collected from 14 medical institutions of different levels in southwest China using a convenience sampling from February to April, 2023. A total of 491 midwives were included. A cross-sectional survey was conducted using a general information questionnaire and the Chinese version of the Perinatal Missed Care. Multiple linear regression analysis was conducted to identify the influencing factors on missed nursing care.Results:Among 491 midwives, there are 6 males and 485 females. 194 midwives aged ≤ 30, 205 midwives aged 31-40 years, and 92 midwives aged ≥41 years. 80.45%(395/491) of midwives reported missing at least one item of nursing care during labor in the past week, and the missing rate of single item ranged from 13.24% (65/491) to 53.36% (262/491). The average score across 23 items of missed nursing care during labor was 1.49 ± 0.58. The average scores of items spanning the three dimensions of basic care, necessary care and postnatal care were 1.67 ± 0.68, 1.36 ± 0.56, and 1.51 ± 0.70, respectively. The average score of 13 items representing reasons for missed nursing care was 1.82 ± 0.71. The average scores of items in three dimensions of communication, labor resources, and material resources were 1.75 ± 0.73, 1.97 ± 0.87, and 1.74 ± 0.83, respectively. The multiple linear regression analyses showed that gender, monthly average income level, and whether overtime hours were included in total working hours were independently associated with missed nursing care (all P<0.05). Conclusions:The current state of missed nursing care during labor needs to be improved. Missed basic care is common, and labor resources are the significant reasons, and is influenced by factors such as demographic and sociological factors. Human resource factors are an important reason for nursing deficiency, and targeted measures should be taken to reduce the occurrence of nursing deficiency.

Objective:To monitor the subtype distributions and drug resistance mutations of human immunodeficiency virus (HIV)-1 in people living with human immunodeficiency virus-1 (PLWH) who had not experienced anti-retroviral therapy (ART) in Henan Province in 2023, so as to provide valuable data for understanding the transmission of HIV-1 resistant strains and selection of ART regimens in Henan Province.Methods:The clinical data and drug resistance of PLWHs who had not experienced ART in the Sixth People′s Hospital of Zhengzhou from January to December 2023 were collected. This study was a cross-sectional study. Plasma samples were collected from patients, and the partial HIV pol gene sequence and the full integrase gene sequence were amplified by reverse transcription-nested polymerase chain reaction. The subtypes of HIV-1 isolates were determined using the online REGA HIV-1 Subtyping Tool. Drug resistance mutations and antiviral drug susceptibility were analyzed by submitting the determined sequences to the Stanford HIV-1 drug resistance database.Results:Among the 1 073 PLWHs who had not experienced ART, sequences in 1 042 were successfully amplified, giving a success rate of 97.11%. A total of 12 subtypes were detected, and the top five subtypes were circulating recombinant form (CRF)07_BC (43.76%, 456/1 042), CRF01_AE (25.91%, 270/1 042), B (20.92%, 218/1 042), CRF55_01B (5.28%, 55/1 042) and CRF08_BC (1.25%, 13/1 042). The incidence of drug resistance mutation was 28.89% (301/1 042). Drug resistance mutation of non-nucleoside reverse transcriptase inhibitors (NNRTI), nucleotide reverse transcriptase inhibitors (NRTI), protease inhibitors (PI) and integrase inhibitors (INSTI) were 20.92%(218/1 042), 4.03%(42/1 042), 3.84%(40/1 042) and 2.98%(31/1 042), respectively. V179 (12.96%, 135/1 042), M184 (2.40%, 25/1 042), Q58 (2.78%, 29/1 042), and E157 (1.44%, 15/1 042) were the most common drug resistance mutation for NNRTIs, NRTIs, PIs and INSTIs, respectively.Conclusions:The distribution of HIV-1 subtypes is diverse, and the incidence of drug resistance mutation is moderate prevalent in PLWHs who have not experienced ART. Drug resistance testing in PLWHs before ART should be closely monitored.
