The interaction between immune response and metabolic regulation can be viewed as a central homeostatic mechanism,dysfunction of which will lead to many diseases.This nonlinear interaction,which has the characteristic of super-complexity,can’t be controlled unless it is studied as a holism and the change of condition is researched.To study this homeostasis,bottom-up method used in system biology is limited.Ying-wei theory of TCM uses another method to describe di erent states of metabolic and immune systems e ectively.The unique approaches and rich experiences applied in TCM are of great value.

There are three kinds of molecular targeted antitumor drugs: inhibitors of membrane?associated therapeutic targets, inhibitors of intracellular signaling pathways, and immunomodulators. Inhibitors of membrane?associated therapeutic targets include epidermal growth factor receptor inhibitors (EGFRIs), KIT and BCR?ABL inhibitors, antiangiogenic agents and multikinase inhibitors. Inhibitors of intracellular signals include inhibitors of the RAS?RAF?MEK?ERK pathway, PI3K?AKT?mTOR pathway and Hedgehog signaling pathway. Inhibitors of cytotoxic T lymphocyte associated?antigen(CTLA) and programmed death 1 (PD?1) belong to immunomodulatory agents. Cutaneous adverse effects of different molecular targeted antitumor drugs share some common features, but also differ from each other. Most of the side effects are dose?dependent and reversible. Management strategies should be adjusted according to the severity of skin eruptions. Dose tapering and even discontinuation of antitumor drugs are necessary for very severe cases, but for mild ones, symptomatic treatment might be enough. This article reviews cutaneous adverse reactions to molecular targeted therapy as well as their prevention and management.

Objective To study the expression of skin aspartic protease (SASPase) in lesions of cutaneous lupus erythematosus (CLE) and its role in the pathogenesis of CLE.Methods Skin samples were resected from the lesions and normal skin of 9 patients with CLE,including 3 cases of subacute cutaneous lupus erythematosus (SCLE),4 cases of discoid lupus erythematosus (DLE) and 2 cases of acute cutaneous lupus erythematosus (ACLE).Keratinocytes were isolated from the tissue samples and cultured in serum-free medium.Total proteins were extracted from the keratinocytes and separated by two-dimensional gel electrophoresis.ImageMaster 2D analysis software was used to assess differentially expressed proteins in keratinocytes between the lesional and normal skin,which were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).The expression levels of SASPase were further determined by Western blot.The data were analyzed statistically by Student's t test.Results Keratinocytes were isolated from the tissue samples and successfully cultured in vitro.Two-dimensional electrophoresis profiles of proteins from the keratinocytes were obtained with high resolution and reproducibility,and the average matching protein spots were about 1200 with the matching rate higher than 80％.As Western blot showed,the relative expression level of SASPase was 0.463 ± 0.018 in keratinocytes from the lesional skin,and 0.145 ± 0.011 in those from the normal skin (P ＜ 0.05).The Western blot results were consistent with those of two-dimensional electrophoresis.Conclusion The initiation and progression of CLE seem to be associated with the abnormal activation and overexpression of SASPase.

Objective To explore the effect of hepatitis B virus(HBV) on the expression of complement 3 (C3) and complement 4 (C4) and its regulatory mechanism.Methods Differentially expressed genes between HepG2 and HepG2.2.15 cells was screened by gene chip,serum complement component 3 (C3) and 4 (C4) levels in patients with HBV infection and in healthy individuals were measured by Immunoturbidimetry,HBV infectious clone pHBV1.3 was transfected into HepG2 cells,and expression of C3 and C4 was measured by RT-PCR and Western blot.Results Expression of C3 and C4 mRNA was lower in HepG2.2.15 cells than in HepG2 cells,serum C3 and C4 levels was much lower in patients with chronic hepatitis B and hepatic carcinoma as compared to healthy individuals (P＜0.05 ).HBV could downregulate the expression of C3 and C4 at mRNA and protein levels.Conclusion HBV may inhibit the expression both in vivo and in vitro.

Objectives To learn the effect of self-recognition-based healthy management on community diabetics. Methods A total of 40 community diabetics were evaluated and trained for 3 months.SPSS11.5 software was used for data analysis. Results At 3 months, some risk factors of diabetes,including body weight, body mass index (BMI), waist circumstance (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP) and 2 h postprandial blood sugar (PBS), were improved (P ＜0. 05). Male patients showed statistically significant reduction in body weight, BMI and WC ( P ＜ 0. 05 ).However, female subjects were found to have significant decline in body weight, BMI, WC, SBP and DBP (P＜0. 05). Those ＞60 year-old had significantly decreased body weight, BMI, WC, SBP, DBP and 2 h PBS ( P ＜ 0. 05). Lower levels of WC, SBP and triglyceride were seen in individuals ＜ 60 year-old ( P ＜0. 05 ). Conclusion Self-recognition-based healthy management could effectively reduce diabetic risk factors and prevent the development of diabetic complications.

AIM: To observe the effect of combined goniosynechialysis in treating absolute glaucoma after trabeculectomy.
METHODS:Phacoemulsification combined goniosynechialysis was performed on 16 patients ( 16 eyes ) with absolute glaucoma after trabeculectomy, and they were followed up for 6 ~12mo, The postoperative intraocular pressure ( IOP ) and anterior chamber depth, preoperative and postoperative medication types (quantity), preoperative and postoperative 1 month's status of anxiety and depression, symptoms of ocular surface were observed. RESULTS: The IOP decreased significantly after phacoemulsification combined goniosynechialysis. The mean IOP was 35. 00±15. 43mmHg preoperatively, and it was 12. 00±6. 69mmHg, 15. 00±4. 26mmHg and 15. 3±5.2mmHg on 1d, 6 and 12mo after the surgery. The statistic difference was found between preoperative and postoperative (t=6. 22, P<0. 05). The anterior chamber depth was 1. 45 ± 0. 19mm before the surgery, and increased to 3. 37±0. 13mm after the surgery (t=6. 65, P<0. 05). After the surgery, 2 patients needed two kinds of drugs, 2 patients needed one kind of drug. After 12mo of follow-up, anxiety and depression status were improved in all 16 patients. Subjective discomfort symptoms of 16 patients such as eye bilges, eye pain were relieved. All of the patients' eyeballs were preserved, and no serious complications.
CONCLUSION: Phacoemulsification combined goniosynechialysis in treating absolute glaucoma after trabeculectomy is a safe and effective surgical option.

Objective To evaluate the academic status of the researchers in pediatric department of Peking university first hospital, we conducted bibliometric analysis of research on the scientific publications. Methods The total number, first authors, and the citing and cited conditions of these papers published from 1999 to 2000 were analyzed by bibliometric methods. Results There were total 513 papers including 275 original articles published in 59 journals from 1999 to 2003.There were 238 papers written in Chinese, of which 188 papers (79 %) were from the core journals. In the 37 original articles written in English, 31 papers(83.8 %) were select-ed by science citation index(SCI).The average of impact factors (IF) of sourcing journals was 1.447(0.107 -7.717). The averages of IF per year ranged from 0. 768 to 2.206.The original articles selected by SCI were totally cited 38 times. Every article was cited 1.41 times in average.Of all 275 papers,each had an average of 9.8 citing reference, increasing from 8.1 in 1999 to 12.0 in 2003.About 80.7 % of those references were written in foreign languages.The Price's index of those papers was 43.2%.Conclusions The number of papers kept improving in the past 5 years, and had a significant improvement in 2003.The authors showes great talents to use English articles as their main information sources. But the utilization of the last published papers in this subject should be im-proved.

Objective : To systematically evaluate the detection of Legionella pneumophila in central air-conditioning systems of public places in China, so as to provide insights into the management of L. pneumophila contamination. Methods: The publications pertaining to L. pneumophila contamination in central air-conditioning systems of public places in China were searched in international and national databases, including CNKI, Wanfang Data, CBM, PubMed and Web of Science from January 1, 2010 to December 31, 2022. The publication quality was evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology. A meta-analysis was performed using the software Stata version 16.0. The pooled detection of L. pneumophila and its 95%CI were estimated. The publication bias was evaluated using Begg's test, and sensitivity analysis was performed with the leave-one-out evaluation for assessment of the robustness of the outcomes. Results: A total of 742 publications were initially searched, and 29 publications were finally included, all of which were cross-sectional studies. The publications included 10 high-quality and 19 moderate-quality studies covering 6 160 samples, and the pooled detection of L. pneumophila was 17.20% (95%CI: 12.80%-21.90%). Subgroup analysis showed a higher detection rate of L. pneumophila in cooling water (21.80%) than in condensed water (5.50%) (P<0.01). According to the criteria defined in Hygienic Specification of Central Air-conditioning Ventilation System in Public Buildings (2006 version), the detection of L. pneumophila was 23.30%, which was higher than the detection (13.20%) according to the Hygienic Specification of Central Air-conditioning Ventilation System in Public Buildings (WS 394-2012) (P<0.05). The detection of L. pneumophila did not vary in place, region or sample (P>0.05). Begg's test showed no significant publication bias, and sensitivity analysis showed robustness of the results. Conclusions The detection of L. pneumophila ranges from 12.80% to 21.90% in central air-conditioning systems of public places in China. Health and environmental protection sectors need to improve the monitoring of L. pneumophila contamination in central air-conditioning systems of public places.
