Cholangiocarcinoma (CCA) is a fatal malignancy with steadily increasing incidence and poor prognosis. Since most CCA cases are diagnosed at an advanced stage, systemic therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, play a crucial role in the management of unresectable CCA. The recent advances in targeted therapies and immunotherapies brought more options in the clinical management of unresectable CCA. This review depicts the advances of targeted therapies and immunotherapies for unresectable CCA, summarizes crucial clinical trials, and describes the efficacy and safety of different drugs, which may help further develop precision and individualization in the clinical treatment of unresectable CCA.

OBJECTIVE To explore the effects of ADRB1 Arg389Gly polymorphisms on the efficacy of bisoprolol， thus providing some information for individualized drug therapy. METHODS A systematic search was conducted in PubMed， Embase， Cochrane Library， CBM， CNKI， and Wanfang Data to retrieve and find out all relevant literature about bisoprolol and ADRB1 Arg389Gly polymorphism from the inception to May 2023. The retrieved literature was screened and selected according to the inclusive and exclusive criteria， thereafter quality assessment was conducted. RevMan 5.4 software was utilized to perform the meta- analysis for the outcome index. RESULTS Overall 7 literature with 1 339 cases were included. Among them， 4 studies provided the changes in systolic blood pressure （SBP）， diastolic blood pressure （DBP） （ΔSBP and ΔDBP）； 4 involving the change （ΔLVEF） of left ventricular ejection fraction （LVEF）. Results of the study showed that there was no statistical significance in the improvement of blood pressure between wild-type group （AA） and mutation group （AG+GG） of ADRB1 Arg389Gly treated with bisoprolol {ΔSBP [SMD＝0.17，95%CI （－0.97，1.31）， P＝0.77]， ΔDBP [SMD＝－0.01，95%CI （－0.65，0.62）， P＝0.97]}； there was no statistical significance in the improvement of ΔLVEF [SMD＝－0.61， 95%CI （－2.74，1.53）， P＝0.58] between 2 groups. CONCLUSIONS ADRB1 Arg389Gly gene polymorphism has no significant influence on the improvement of SBP， DBP， and LVEF in cardiovascular patients who use bisoprolol.

Objective:To investigate the clinical efficacy and safety of rituximab combined with chemotherapy in the treatment of small B-cell lymphoma.Methods:A retrospective series study was conducted. The clinical data of 44 small B-cell lymphoma patients with complete follow-up data who received rituximab combined with chemotherapy in Zaozhuang Municipal Hospital from January 2017 to August 2022 were retrospectively analyzed. The clinicopathological characteristics and prognosis of patients were also analyzed.Results:All the 44 patients with small B-cell lymphoma included 28 males and 16 females; the age was (62±13) years. Among the 44 patients, there were 27 cases of chronic lymphocytic leukemia, 7 cases of follicular lymphoma, 2 cases of lymphoplasmacytic lymphoma/Waldenstr?m macroglobulinemia, 3 cases of splenic marginal zone lymphoma, 1 case of lymph node marginal zone lymphoma and 1 case of hair-cell leukemia, 3 cases of unclassified B-cell chronic lymphocyte proliferative disease. Follow-up time [ M ( Q1, Q3)] was 35.5 months (18.5 months, 52.0 months). The complete remission (CR) rate, partial remission rate and the objective remission rate was 61.36% (27/44), 29.55% (13/44) and 90.91% (40/44), respectively. There were statistically significant differences in CR rates in patients with different expression levels of β 2-microglobulin, lactate dehydrogenase and ZAP-70 (all P < 0.05), while the differences in CR rates among patients with different age, gender and bone marrow infiltration were not statistically significant (all P >0.05). Until the last follow-up, the median overall survival (OS) time was not reached, the median progression-free survival (PFS) time was 65 months. The incidence of hematological adverse reactions was 27.27% (12/44), which was well tolerated. No serious non-hematological adverse reactions were observed. Conclusions:Rituximab combined with chemotherapy could improve the therapeutic effect, prolong PFS and OS time of patients with small B-cell lymphoma. The adverse reactions can be tolerated.

Objective: This study aimed to determine the predictive performance of non-contrast CT (NCCT) signs for hemorrhagic growth after intracerebral hemorrhage (ICH) when stratified by onset-to-imaging time (OIT). Materials and Methods: 1488 supratentorial ICH within 6 h of onset were consecutively recruited from six centers between January 2018 and August 2022. NCCT signs were classified according to density (hypodensities, swirl sign, black hole sign, blend sign, fluid level, and heterogeneous density) and shape (island sign, satellite sign, and irregular shape) features. Multivariable logistic regression was used to evaluate the association between NCCT signs and three types of hemorrhagic growth: hematoma expansion (HE), intraventricular hemorrhage growth (IVHG), and revised HE (RHE). The performance of the NCCT signs was evaluated using the positive predictive value (PPV) stratified by OIT. Results: Multivariable analysis showed that hypodensities were an independent predictor of HE (adjusted odds ratio [95% confidence interval] of 7.99 [4.87–13.40]), IVHG (3.64 [2.15–6.24]), and RHE (7.90 [4.93–12.90]). Similarly, OIT (for a 1-h increase) was an independent inverse predictor of HE (0.59 [0.52–0.66]), IVHG (0.72 [0.64–0.81]), and RHE (0.61 [0.54– 0.67]). Blend and island signs were independently associated with HE and RHE (10.60 [7.36–15.30] and 10.10 [7.10–14.60], respectively, for the blend sign and 2.75 [1.64–4.67] and 2.62 [1.60–4.30], respectively, for the island sign). Hypodensities demonstrated low PPVs of 0.41 (110/269) or lower for IVHG when stratified by OIT. When OIT was ≤ 2 h, the PPVs of hypodensities, blend sign, and island sign for RHE were 0.80 (215/269), 0.90 (142/157), and 0.83 (103/124), respectively. Conclusion Hypodensities, blend sign, and island sign were the best NCCT predictors of RHE when OIT was ≤ 2 h. NCCT signs may assist in earlier recognition of the risk of hemorrhagic growth and guide early intervention to prevent neurological deterioration resulting from hemorrhagic growth.

OBJECTIVE To develop an individualized medication list for elderly patients by evidence-based pharmacy method， and to support clinical decisions on rational use of METHODS　Firstly， drugs with risk genetic information were screened out by systematically reviewing evidence-based pharmacy information. Secondly， researchers investigated the included drugs in lists from different data E- sources. Drugs included in three or more data sources and drugs proposed by the expert committee were then included in the medication list. Thirdly， for the drugs included in two data sources， researchers designed questionnaires to investigate the necessity of drug-related gene testing. According to the scoring results of the expert questionnaire， drugs with higher scores were included in the list. Data sources included real-world data （list of high frequency medication in hospitals， high frequency medication for elderly outpatients and inpatients in National Health Care Claims Data， drugs related to frequent medication errors and so on） and evidence-based pharmacy evidence （the websites of Clinical Pharmacogenomics Implementation Consortium， Dutch Pharmacogenetics Working Group， Food and Drug Administration and so on）. RESULTS　The study obtain 68 drugs with risk genetic information which were included in three data sources. Combined with 23 drugs proposed by the expert committee， a list containing 74 drugs was preliminarily formed after de-duplication. A total of 37 drugs included in two databases with risk genetic information were scored through the questionnaire survey to form a supplementary list of 26 drugs. This is the final composition of the list of 100 drugs developed in this study. Among them， there are 43 drugs for the central nervous system， 15 drugs for the cardiovascular system， 12 anti-tumor drugs and so on. Twelve drugs were included in six or more data sources， which mainly consisted of drugs for digestive system， all proton pump inhibitors. CONCLUSION　In this study， a list of 100 commonly used drugs which require individualized medication for the elderly was developed by evidence-based pharmacy method. The drug list will be updated in time as available evidence changes， and can provide guidance for rational use of medicines for elderly patients.

Objective:To evaluate the effect of sufentanil on activation of Schwann cells after peripheral nerve injury in mice.Methods:Eighty healthy pathogen-free male Balb/c mice, aged 6-8 weeks, weighing 18-22 g, were divided into 4 groups ( n=20 each) using a random number table method: peripheral nerve injury group (group PNI), high dose sufentanil group (group H), medium dose sufentanil group (group M) and low dose sufentanil group (group L). The model of unilateral sciatic nerve transaction was established in ketamine-anesthetized mice.Immediately after establishment of the model, sufentanil 10, 5 and 2.5 μg/kg was injected intraperitoneally once a day for 3 consecutive days in H, M and L groups, respectively, while the equal volume of normal saline was given instead in group PNI.Sciatic function index (SFI) was calculated at 4, 8 and 12 weeks after establishment of the model.At 2, 4, 8 and 12 weeks, 5 mice in each group were sacrificed, and segments of the injuried ipsilateral sciatic nerve were removed for examination of the ultrastructure of the sciatic nerve (with a transmission electron microscope) and for detection of the expression of glial fibrillary acidic protein (GFAP) of sciatic nerve (by immunohistochemistry). Results:Compared with group PNI, SFI was significantly increased, and the expression of GFAP was up-regluated at each time point after establishment of the model in H and M groups ( P<0.05) and no significant change was found in SFI and GFAP expression after establishment of the model in group L ( P>0.05). Compared with group L, SFI was significantly increased, and GFAP expression was up-regluated in H and M groups ( P<0.05). There was no significant difference in SFI and GFAP expression between group H and group M ( P>0.05). The thickness of myelin lamellae was dense, and the proliferation of Schwann cells was not marked in H and M groups.The thickness of myelin lamellae was thin, and the proliferation of Schwann cells was marked in L and MO groups. Conclusion:The mechanism by which sufentanil improves repair after peripheral nerve injury may be related to promoting activation of Schwann cells in mice.
