To investigate the characteristics of the cold and heat properties of each resolution component of Açaí and the material basis of cooling by observing the effect of resolution components, such as Açaí oil, alcohol extract and water extract, on the neurotransmitter, endocrine hormone and immune factor level in mice with deficiency-heat and deficiency-cold syndrome. KM male mice were randomly divided into 12 groups, namely blank group, deficiency-heat model group, deficiency-heat+Açaí group, deficiency-heat+Açaí oil group, deficiency-heat+Açaí alcohol extract group, deficiency-heat+Açaí water extract group, deficiency-cold model group, deficiency-cold+Cinnamomi Cortex group, deficiency-cold+Açaí group, deficiency-cold+Açaí oil group, deficiency-cold+Açaí alcohol extract group, and deficiency-cold+Açaí water extract group. The mice in deficiency-heat group were given with thyroid tablet solution(160 mg·kg~(-1)), and the mice in deficiency-cold group were given with hydrocortisone solution(25 mg·kg~(-1)) by intragastric administration every afternoon for 14 days. The mice in each administration group received corresponding drug. The neurotransmitter, endocrine hormone and immune factor levels in the mice were measured after the experiment. The Açaí alcohol extract, consistent with the Açaí powder, showed a regulatory effect on the deficiency-heat model mice; Açaí oil and its water extract were consistent with Cinna-momi Cortex, showing a regulatory effect on the deficiency-cold model mice. In this study, on the basis of proving that Açaí was was cool in property, it also revealed that alcohol extract of Açaí was cool while oil and water extract were warm in property based on the effect of Açaí on neuro-endocrine-immune network. The results suggested that the medicine property of Açaí was the result of the comprehensive action of the resolution components with different properties, and the alcohol extract of Açaí was proved as the material basis of Açaí cold medicine by using the methods of homogeneous comparison and heterogeneous disproval.

The aim of this paper was to study the effect of Lepidium meyenii(Maca) on cyclic nucleotides, neurotransmitter levels and hypothalamic-pituitary-adrenal axis and immunization of deficiency-cold and deficiency-heat syndrome rats, in order to explore the cold and hot medicinal properties of Maca. SD rats were divided into blank group, deficiency-cold syndrome group, Cinnamomi Cortex of deficiency-cold syndrome(30 g·kg~(-1)) group, high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)), deficiency-heat syndrome group, Phellodendri Chinensis Cortex(PCC) of deficiency-heat syndrome(5 g·kg~(-1)), and high and low-dose Maca groups(2.4, 1.2 g·kg~(-1)). The rats were treated with intramuscular injection of hydrocortisone(20 mg·kg~(-1)) or dexamethasone sodium phosphate(0.35 mg·kg~(-1)) for 21 days to set up the deficiency-cold and deficiency-heat model. The levels of cAMP, cGMP, NE, DA, 5-HT, CRH, ACTH, CORT and IgM, IgG, C3, C4 were detected by radio immunoassay. Both the high-dose Maca group and the low-dose Maca group can significantly improve the overall state and body weight of rats with deficiency-cold syndrome(P<0.01, P<0.05), significantly increasing cAMP, cAMP/cGMP, NE, DA, ACTH(P<0.01, P<0.001), and significantly decreasing 5-HT(P<0.01, P<0.001). However, high-dose and low-dose Maca groups could not improve the deficiency-heat syndrome, and the levels of cAMP, cGMP, cAMP/cGMP, NE, DA, 5-HT and ACTH were not statistically significant. Maca had a significant regulatory effect on CORT, IgM, IgG and C3 content of rats with deficiency-cold and deficiency-heat syndrome(P<0.01, P<0.05, P<0.001). Maca showed the same effect with Cinnamomi Cortex in adjusting the levels of deficiency-cold rats, but in opposition to Phellodendri Chinese Cortex. This paper confirmed that Maca was slightly warm based on its effect on cyclic nucleotide levels and neuro-endocrine-immune networks by the pharmacological experimental method.

Traditional Chinese medicine Tripterygium wilfordii Hook.f( TWHF) is a natural botanical drug in China. It has complex chemical compositions and has been used for a long history. TWHF was used as an insecticide to protect crops at early stage,and it was later found to have significant effects in the treatment of rheumatoid arthritis,attaining great concerns. With further researches,it was found that TWHF can treat various diseases in the medical field due to a variety of pharmacological activities such as anti-cancer,neuroprotection,anti-inflammatory and immune-suppressing,particularly. Multiple extracts of TWHF have unique immunosuppressive function,playing an immune role through multi-target and multi-channel,with significant effect in the treatment of autoimmune diseases. As an immune-suppressing drug,TWHF is worthy of in-depth research due to its broad application prospects. While achieving good clinical efficacy,reports about its toxic effects to multiple systems of the body are also increasing,greatly hindering its clinical application. In order to fully understand the immune-suppressing function of TWHF and reduce or avoid the occurrence of toxic and side effects,we summarized recent progress of TWHF on the immune organs,cells and factors in recent years,as well as the pharmacology and toxic effects,hoping to provide a scientific and reasonable reference for its wider use in clinical treatment.

In recent years, epidermal growth factor receptor tyrosine kinase inhibitors have been recommended by many guidelines as first-line drugs for advanced non-small cell lung cancer (NSCLC) with EGFR gene mutations and no resistance. However, with the prolongation of medication time, most appear acquired resistance. In recent years, breakthroughs in inhibitors of programmed death-1 (PD-1) and its ligand (PD1 ligand, PD-L1) have rapidly changed the therapeutic model of NSCLC. Recent studies have shown that the efficacy of immune checkpoint inhibitors in EGFR-mutant NSCLC patients is not satisfactory, which might be caused by low PD-L1 expression, inhibitory immune microenvironment and low tumor mutation load. This review will elaborate the immune microenvironment of NSCLC patients with EGFR mutation, the latest study progression of immune checkpoint inhibitors and its combined with TKI, expecting to bring new hopes for the treatment of EGFR-mutant NSCLC patients.

For the basic research on the traditional Chinese medicine(TCM), objective syndrome of traditional Chinese medicine and evaluation criteria of traditional Chinese medicine compounds are hardly to break though. While, the modern immunology points out that the body is a counterbalance state and immune imbalance is the root of sickness. The thinking mode of treating diseases in traditional Chinese medicine is also "balance", considering disease is the result of bias which present the imbalance of "Yin counters Yang", "exterior counters interior", "cold counters heat" and "weak counters strong". The Chinese herbal compound formula preparation was applied on disease therapy based on theory of Chinese medicine, which was confirmed by long period clinical application. It is composed of multi-compounds and has the characteristic of multi-targeting. Integrative medicine has spawned pan-immunomics, and the evaluation of immune function (immune balance) has become an important basis for diagnosis and treatment models of integrative medicine. In addition, balance is the core idea of whole-systemic conception of traditional Chinese medicine. Therefore, we speculate that immune balance under pan-immunomic can bridge the traditional Chinese medicine and modern integrative medicine and is the important basis for objective syndrome of traditional Chinese medicine and evaluation criteria of traditional Chinese medicine compounds. According to the bridging theory, we attempt to utilize informatics and statistical methods to construct an evaluation system for pharmacodynamics of traditional Chinese medicine based on its moderate regulation and the balanced adjustment of immunity under pan-immunomic, which further reveal the scientific essence of the whole-systemic view of traditional Chinese medicine. This research brings out a new valuable strategy and provides a theoretical basis for accelerating the transformation of traditional Chinese medicine, especially the exploitation of Chinese herbal compound formula, and constructing the new drug innovation and review system for traditional Chinese medicine. Besides as a reference for traditional Chinese medicine objective syndrome and pharmacodynamics of traditional Chinese medicine compounds, the evaluation system can screen the immunity of sub-health population also. With the continuous accumulation of clinical sample and data, the evaluation system will be more accurate and intelligent.

Chronic prostatitis is a common male disease, and its pathogenesis is not yet clear. Most scholars believe that oxidative stress and immune imbalance are the keys to the occurrence and progression of chronic prostatitis. Currently immunotherapy of chronic prostatitis remains in the exploratory stage. This article relates the active ingredients of 5 Chinese medicinal herbs (total glucosides of paeony, tripterigium wilfordii polglycosidium, curcumin, geniposide, and quercetin) for the treatment of chronic prostatitis and their possible action mechanisms as follows: 1) inhibiting the immune response and activation and proliferation of T-cells, and adjusting the proportion of Th1/Th2 cells; 2) upregulating the expression of Treg and enhancing the patient's tolerability; 3) suppressing the activation of the NF-kB factor, reducing the release of iNOS, and further decreasing the release of NO, IL-2 and other inflammatory cytokines, which contribute to the suppression of the immune response; 4) inhibiting the production of such chemokines as MCP-1 and MIP-1α in order to reduce their induction of inflammatory response. Studies on the immune mechanisms of Chinese medicinal herbs in the treatment of chronic prostatitis are clinically valuable for the development of new drugs for this disease.

Despite the fact that any drug can be an impending cause of hypersensitivity reactions, Ibuprofen, an over-the-counter drug used extensively as an analgesic and antipyretic in Asia, is considered to be relatively safe. But herein we report a rare extremely 'rapid onset' occurrence of a severe case of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) in a 22-year-old male, induced by 3 doses of 400 mg of Ibuprofen taken at 8-hour interval for eye pain, probably the first case report of rapid onset of TEN by nonsteroidal antiinflammatory drugs in Nepal. SJS and TEN are idiosyncratic, delayed hypersensitivity inflammatory adverse drug reactions that are severe adverse cutaneous drug reactions which predominantly involve the skin and mucous membranes and are linked with high morbidity and mortality. Nevertheless, removal of ibuprofen and its metabolites with plasma exchange and treatment with antibiotics and intravenous corticosteroids along with supportive therapy improved the course of the disorder. This rare case report addresses the fact that severe hypersensitivity reactions can occur with Ibuprofen, which can be potentially dangerous and life threatening. It is thus important for the clinicians to be alert to such severe hypersensitivity reactions even with drugs which are deemed to be probably safe.

Drug-induced hypersensitivity pneumonitis results from interactions between pharmacologic agents and the human immune system. We describe a 54-year-old man with hypersensitivity pneumonitis caused by cephalosporins with identical R1 side chains. The patient, who complained of cough with sputum, was prescribed ceftriaxone and clarithromycin at a local clinic. The following day, he complained of dyspnea, and chest X-ray revealed worsening of inflammation. Upon admission to our hospital, antibiotics were changed to cefepime with levofloxacin, but his pneumonia appeared to progress. Changing antibiotics to meropenem with ciprofloxacin improved his symptoms and radiologic findings. Antibiotics were de-escalated to ceftazidime with levofloxacin, and his condition improved. During later treatment, he was mistakenly prescribed cefotaxime, which led to nausea, vomiting, dyspnea and fever, and indications of pneumonitis on chest X-ray. We performed bronchoalveolar lavage, and the findings included lymphocytosis (23%), eosinophilia (17%), and a low cluster of differentiation (CD) 4 to CD8 ratio (0.1), informing a diagnosis of drug-induced pneumonitis. After a medication change, his symptoms improved and he was discharged. One year later, he was hospitalized for acute respiratory distress syndrome following treatment with ceftriaxone and aminoglycosides for an upper respiratory tract infection. After steroid therapy, he recovered completely. In this patient, hypersensitivity reaction in the lungs was caused by ceftriaxone, cefotaxime, and cefepime, but not by ceftazidime, indicating that the patient's hypersensitivity pneumonitis was to the common R1 side chain of the cephalosporins.
