Clinical analysis of liver dysfunction induced by SHR-1210 alone or combined with apatinib and chemotherapy in patients with advanced esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Action Mechanism of Chinese Medicine Polysaccharides in Prevention and Treatment Diabetes and Its Complications：A Review / 中国实验方剂学杂志

Diabetes is a metabolic disease mainly characterized by hyperglycemia due to inadequate insulin secretion. And persistent hyperglycemia can cause chronic damage or dysfunction of eyes， kidneys， heart， blood vessels and nerves. Polysaccharides are high molecular carbohydrates polymerized by glycosidic bonds from more than 10 monosaccharide molecules of the same or different types. They have the advantages of wide sources， high safety and low toxic and so on. As one of the important effective components of traditional Chinese medicine， polysaccharides have biological activities such as immune regulation， anti-oxidation， anti-tumor， lowering blood sugar and so on. The structure is directly related to biological activities， and the advanced structure of polysaccharides is based on the primary structure. Exploring the primary structure of polysaccharides is the key task of lowering blood sugar and improving diabetic complications. This paper summarizes the monosaccharide composition of the primary structure of Chinese medicine polysaccharides， and the mechanism of Chinese medicine polysaccharides improving diabetes is emphasized by increasing the secretion and release of insulin， increasing the islet β cell number， upregulating insulin receptor level， improving glucose and lipid metabolism， inhibiting inflammatory response， improving oxidative stress and regulating phosphatidylinositol-3-kinase（PI3K）/protein kinase B （Akt）， mitogen activated protein kinase， cyclic adenosine monophosphate（cAMP）/protein kinase A（PKA） and adenosine monophosphate activated protein kinase（AMPK） signaling pathways. At the same time， we also summarized the prevention and treatment of Chinese medicine polysaccharides in diabetic nephropathy， diabetic cardiomyopathy， diabetic ophthalmopathy and diabetic peripheral neuropathy， in order to provide a theoretical basis for new drug development and clinical application of Chinese medicine polysaccharides in the intervention of diabetes and its complications.

Prognostic analysis of patients with liver metastases from colorectal cancer treated with different modes of therapy / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the potential prognostic factors for patients with liver metastases from colorectal cancer treated with different modes of therapy.</p><p><b>METHODS</b>The clinicopathological data of 300 patients with liver metastases from colorectal cancers were retrospectively reviewed and analyzed.</p><p><b>RESULTS</b>The median survival of patients with recurrence (MSR) treated with complete and palliative resection of liver metastases and unresectable patients was 48, 19 and 18 months, respectively (P = 0.000). In patients with unresectable liver metastases, systemic chemotherapy plus regional therapy demonstrated a median survival time of 23 months, significantly longer than the 6 months in untreated patients (P = 0.000). Patients who showed response to the first-line therapy demonstrated an improved survival versus the patients who had no response, with a median survival time of 24 vs. 16 months (P = 0.000). Univariate analysis revealed that resection modes of primary diseases and liver metastases, treatment modality for liver metastases, and response to first-line therapy were prognostic factors. Multivariate analysis showed that resection modes of liver metastases, multimodality treatment after liver metastases, and the response to first-line therapy were all independent prognostic factors for patients with liver metastases from colorectal cancer.</p><p><b>CONCLUSION</b>Resection of liver metastases, multimodality treatment after liver metastases, and response to first-line chemotherapy are all independent prognostic factors for patients with liver metastasis from colorectal cancer.</p>

<p><b>OBJECTIVE</b>This phase II clinical trial was designed to evaluate the efficacy and toxicity of recombinant human interleukin-11 (rhIL-11) derivative manufactured in China in the prevention and treatment of chemotherapy-induced thrombocytopenia in cancer patients.</p><p><b>METHODS</b>A total of 100 cancer patients with chemotherapy-induced thrombocytopenia (< or = 75 x 10(9)/L) were studied by self-cross control. Ninty-one of them received 2 cycles of chemotherapy. In the first cycle (control cycle) the patients received chemotherapy only, while in the second cycle (treatment cycle), the patients were given subcutaneous injection of rhIL-11 derivative (40 microg.kg(-1).d(-1)) once daily after chemotherapy for 10 consecutive days or more until platelet count reached > or = 300 x 10(9)/L.</p><p><b>RESULTS</b>1. The patients with platelet count of < or = 75 x 10(9)/L was 89/89 in the control cycle and 44/89 in the treatment cycle (P = 0.00). The recovery time to the normal platelet count was 1-47 days (median 9 days) in the control cycle, and 1-18 days (median 5.5 days) in treatment cycle (P = 0.00). 2. Patients with platelet count of < or = 50 x 10(9)/L was 56/89 in the control cycle and 20/89 in the treatment cycle (P = 0.00). The recovery time to normal platelet count was 1-31 days (median 9 days) in the control cycle and 3-13 days (median 6 days) in the treatment cycle (P = 0.05). 3. The median nadir platelet count was 44 x 10(9)/L (range: 10 x 10(9)/L-75 x 10(9)/L) in the control cycle, and 83 x 10(9)/L (range: 10 x 10(9)/L-310 x 10(9)/L) in the treatment cycle (P = 0.00). The time of recovery to the normal platelet count was 1-31 days (median 6 days) in the control cycle, and 0-13 days (median 2 days) in the treatment cycle (P = 0.00). 4. Nine of 89 evaluable patients required platelet transfusion in the control cycle versus 1 of 89 patients in treatment cycle (P = 0.01), and the total platelet transfusion was 10 times in the control cycle versus once in the treatment cycle (P = 0.01). 5. The major adverse events associated with rhIL-11 derivative were: headache, fatigue, myalgia/arthralgia, edema and palpitation, etc.</p><p><b>CONCLUSION</b>rhIL-11 derivative can be safely and effectively used for the prevention and treatment for chemotherapy-induced thrombocytopenia.</p>
