A 67-year-old male patient with esophageal cancer received sintilimab and chemotherapy [sintilimab injection 200 mg by IV infusion, 1 day before chemotherapy, paclitaxel (albumin bound) 200 mg by IV infusion on day 1 and 300 mg on day 5, and nedaplatin 80 mg by IV infusion on day 1 and 70 mg on day 2, 21 days as 1 cycle] for 4 cycles. Later, due to mediastinal lymph node metastasis, the patient received sintilimab and palliative radiotherapy one time. Eight days later, the patient developed urinary frequency, urgency and pain, urine routine showed 638 red blood cells/μl, and 2 141 white blood cells/μl. The T-cell test for mycobacterium tuberculosis infection was positive, and cystoscopy showed diffuse redness and swelling of bladder mucosa. The patient was diagnosed with immune-related cystitis and bladder tuberculosis, which was considered to be related to sintilimab. Methylprednisolone sodium succinate and anti-tuberculosis treatment were given. After 5 days of treatments, the patient′s aforementioned symptoms were improved and the urine routine returned to normal. Afterwards, sintilimab was not used again and relevant symptoms did not recur.

OBJECTIVE To screen and quantitatively analyze differential quality markers (Q-Marker) in Zingiber officinale mixed and triturated with Schisandra chinensis (ZMTS) before and after processing. METHODS HPLC fingerprints of before processing[Z. officinale complicated with S. chinensis (ZWS)]and after processing (ZMTS) (10 batches each) were established. The differences of Q-Markers before and after processing were screened by the chemical pattern recognition method and Q-Marker "five principles",and the contents were determined. RESULTS A total of 14 common peaks were identified in the fingerprints of ZWS,22 common peaks were identified in the fingerprints of ZMTS,and 8 components were identified. Differential Q-Marker were screened by chemical pattern recognition and Q-Marker "five principles",i. e. 6-gingerol,schisandrol A,schisandrol B,8-gingerol,10-gingerol,schisandrin A,schisandrin B,schizandrin C. The average contents of the 8 differential Q-Markers in ZMTS were 229.46,244.48,39.96,44.12,61.17,47.82,100.11 and 9.70 μg/g,respectively. The average contents of the 4 differential Q-Markers (6-gingerol,schisandrol A,schisandrol B,8-gingerol) in ZWS were 112.58,19.01,26.74 and 5.98 μg/g,respectively. CONCLUSIONS In this study,the differential Q-Markers before and after ZMTS processing are screened. The contents of the Q-Markers in ZMTS after processing are higher than those before processing.

Objective:To explore the definition and implications of occupational attractiveness among long-term caregivers.Methods:The Walker and Avant concept analysis method was used to define the concept of occupational attractiveness among long-term caregivers.Results:Attributes of occupational attractiveness of long-term caregivers were: (ⅰ) a strength or ability; (ⅱ) mutual attraction between long-term care occupations and incumbents and potential job seekers; (ⅲ) to attract potential job seekers and satisfying their willingness to work; (ⅳ) to retain and motivate in-service long-term care personnel, and enabling them to develop the professional identity and career development.Conclusions:This concept is defined from the perspective of nursing practice in the elderly care service industry in China and combined with the characteristics of long-term caregivers at this stage. It provides clear conceptual support for further relevant research, and provides certain theoretical and practical guidance for the long-term care work of elderly care institutions, communities and families in China.

Objective:To investigate the effects of modified Sijunzi Decoction on myelosuppression in moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency and analyze the underlying mechanism. Methods:A total of 100 moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency who received treatment in Lishui Hospital of Traditional Chinese Medicine, China were included in this study. They were randomly assigned to receive chemotherapy with paclitaxel combined with cisplatin (control group, n = 50) or treatment with modified Sijunzi Decoction based on chemotherapy with paclitaxel combined with cisplatin (observation group, n = 50). Myelosuppression, traditional Chinese medicine symptom score, cellular immune function, serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor, and the dosage of recombinant human granulocyte-colony stimulating factor. Results:After treatment, the incidence of leucopenia, thrombocytopenia, hemoglobinopenia and neutropenia in the observation group were 60% (30/50), 18% (9/50), 18% (9/50) and 62% (31/50), respectively, which were significantly lower than those in the control group [90% (45/50), 30% (15/50), 32% (16/50) and 92% (46/50), χ2 = 6.979, 7.025, 6.534, 6.134, all P < 0.001]. The complete remission rate in the observation group was significantly higher than that in the control group [30% (15/50) vs. 8% (4/50), χ2 = 9.018, P < 0.001]. The traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( t = 6.982, P < 0.05). CD 8+, CD 4+ and CD 3+ levels in the observation group were (25.16 ± 2.87)%, (38.76 ± 4.16)%, (48.83 ± 5.61)%, respectively, and they were (28. 89 ± 4.02)%, (34.10 ± 4.59)%, (41.12 ± 77)%, respectively in the control group. There were significant differences in CD 8+, CD 4+ and CD 3+ levels between the observation and control groups ( t = 6.392, 6.235, 5.983, all P < 0.05). The dosage of recombinant human granulocyte-colony stimulating factor in the observation group was significantly lower than that in the control group [(2 567.34 ± 308.25) μg vs. (3 917.82 ± 411.67) μg, t = 11.258, P < 0.05]. Serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor were (25.53 ± 7.86) ng/L and (278.34 ± 28.74) ng/L, which were significantly higher than those in the control group [(21.30 ± 3.12) ng/L, (204.17 ± 11.98) ng/L, t = 9.136, 8.856, both P < 0.05]. Conclusion:Modified Sijunzi Decoction for the treatment of moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency can decrease the incidence of myelosuppression possibly through increasing serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor and improving the immune function.

Netrin-1, an axon guidance factor, and its receptor UNC5B play important roles in axonal development and angiogenesis. This study examined netrin-1 and UNC5B expression in kidneys with diabetic kidney disease (DKD) and investigated their roles in angiogenesis. Netrin-1 and UNC5B were upregulated in streptozotocininduced DKD Wistar rats, and their expression was compared with that in healthy controls. However, exogenous netrin-1 in UNC5B-depleted human renal glomerular endothelial cells (HRGECs) inhibited cell migration and tubulogenesis. This effect was likely associated with SRC pathway deactivation. Netrin-1 treatment also eliminated the pro-angiogenic effects of exogenous VEGF-165 on UNC5B-silenced HRGECs. These results indicate that UNC5B antagonizes netrin-1 and that UNC5B upregulation contributes partly to enhancing angiogenesis in DKD. Therefore, introducing exogenous netrin-1 and depleting endogenous UNC5B are potential strategies for reducing the incidence of early angiogenesis and mitigating kidney injury in DKD.

Calnexin is a lectin-like molecular chaperone protein on the endoplasmic reticulum, mediating unfolded protein responses, the endoplasmic reticulum Ca homeostasis, and Ca signals conduction. In recent years, studies have found that calnexin plays a key role in the heart diseases. This study aims to explore the role of calnexin in the activation of cardiac fibroblasts. A transverse aortic constriction (TAC) mouse model was established to observe the activation of cardiac fibroblasts , and the cardiac fibroblasts activation model was established by transforming growth factor β1 (TGFβ1) stimulation. The adenovirus was respectively used to gene overexpression and silencing calnexin in cardiac fibroblasts to elucidate the relationship between calnexin and cardiac fibroblasts activation, as well as the possible underlying mechanism. We confirmed the establishment of TAC model by echocardiography, hematoxylin-eosin, Masson, and Sirius red staining, and detecting the expression of cardiac fibrosis markers in cardiac tissues. After TGFβ1 stimulation, markers of the activation of cardiac fibroblast, and proliferation and migration of cardiac fibroblast were detected by quantitative PCR, Western blot, EdU assay, and wound healing assay respectively. The results showed that the calnexin expression was reduced in both the TAC mice model and the activated cardiac fibroblasts. The overexpression of calnexin relieved cardiac fibroblasts activation, in contrast, the silencing of calnexin promoted cardiac fibroblasts activation. Furthermore, we found that the endoplasmic reticulum stress was activated during cardiac fibroblasts activation, and endoplasmic reticulum stress was relieved after overexpression of calnexin. Conversely, after the silencing of calnexin, endoplasmic reticulum stress was further aggravated, accompanying with the activation of cardiac fibroblasts. Our data suggest that the overexpression of calnexin may prevent cardiac fibroblasts against activation by alleviating endoplasmic reticulum stress.
