Human epidermal growth factor receptor 2 (HER2) belongs to the transmembrane glycoprotein receptor family. Overexpression of HER2 could directly lead to tumorigenesis and metastasis. This phenomenon could be observed in the breast cancer, ovarian cancer, gastric cancer, lung cancer and prostate cancer. Compared with the conventional chemotherapy, the targeted treatment of antibody is more specific and has lower side effects. This review describes the current status of monotherapy and combination therapies of anti-HER2 antibodies, trastuzumab and pertuzumab, with chemotherapeutic drugs. The development trends of new formats of anti-HER2 antibody drugs such as bispecific antibody, immunotoxin are also discussed.

Monoclonal antibody-targeted therapy has been a hot spot in current clinical cancer treatment. As current antibody drugs have large molecule sizes leading to poor tissue penetration, and high dosage in clinical application leading to high cost, to overcome the problems, the development of new antibody drugs with miniaturization and high potency has become a new trend. In recent years, the conjugates of monoclonal antibodies and cytotoxins, called antibody-drug conjugates (ADCs), have entered the arsenal of anti-cancer drugs, becoming a new format of antibody drugs and attracting extensive attentions. The ADC molecule usually consists of antibody, linker and effector molecule. According to different effector molecules, ADCs can be divided into three categories as chemo-conjugates, immunotoxins and radio-conjugates. When ADC molecules are internalized into cancer cells, cytotoxins will be released by chemical, enzyme degradation or by action of lysosomal proteases, then kill targeted cells by inhibiting protein synthesis, depolymerizing microtubules or breaking double-strand DNA. Recently, two ADC drugs have been approved by the US FDA and more ADC drug candidates are in clinical phase II or III trials which show significantly clinical effects and attracting much attention and competition of pharmaceutical enterprises. In this review, antibody conjugates in the past and present will be summarized and the future development trends and challenges of this type of antibody drugs will be discussed.

OBJECTIVEThis study aimed to investigate the expression and role of the mitogen activated protein kinases (ERK1/2, P38, JNK) in phosgene induced lung injury in rats in vivo.

METHOD30 male wistar rats were randomized into the group as follows, Gas inhalation control group, Phosgene inhalation group, and the following groups of the inhibitors of MAPK, involving SP600125, PD98059 and SB203580, 6 animals in each group, we copy the model of phosgene-induced lung injury, used the directional flow-inhalation device, the air control group inhaled the air, and the intervention groups were given PD98059 (intraperitoneal injection), SB203580 (hypodermic injection), SP600125 (intravenous) respectively before the inhalation of phosgene. The locations and quantities of three subfamilies of MAPKs (ERK1/2, P38, JNK) and p-MAPKs (p-ERK1/2, p-P38, p-JNK) were analyzed by immunohistochemistry and Western Blot analysis respectively; The histopathological changes of lung tissues, the number of neutrophil cells and the W/D were examined.

RESULTThere were rare p-ERK1/2, p-P38 and p-JNK positive expression in alveolar and airway epithelial cells in control group. while the positive cells increased strikingly in phosgene inhalation groups, these cells involved in this process mainly included alveolar epithelial cells, air way epithelial cells, pleural mesothelial cells, infiltrative inflammatory cells, interstitium fibrocytes. After the intervention of the specific inhibitor, the positive cells decreased. As Western Blot analysis show, Protein quantities of p-P38 and p-JNK were higher in phosgene inhalation groups than those in control group, and the differences were significant (P < 0.05). Protein quantities of p-ERK1/2, p-P38 and p-JNK were lower in intervention groups than phosgene inhalation group, and the differences were significant (P < 0.05, P < 0.01). The lung injury in phosgene inhalation groups was more severer compared with the control group, the typical pathological characters of acute lung injury were discovered, the increase of the number of neutrophil cells and W/D. After the intervention of the specific inhibitor SP600125 and SB203580, the number of neutrophil cells and W/D reduced, and the differences were significant (P < 0.05, P < 0.01).

CONCLUSIONPhosgene inhalation may activate the MAPK signaling pathway, and the expression of the phosphorylation of MAPKs increased, especially the P38 ang JNK. The results may contribute to the lung injury induced by phosgene.

Objective:This study aimed to investigate temporal trends in Event survival after OHCA from 2015 to 2019 in Jiading district Shanghai. And analysis the influencing factors.Methods:This was a population based observational cohort study evaluating the temporal trends in survival after OHCA, we included consecutive patients who experienced an OHCA between January 1,2015 and December 31, 2019, we included all adult patients aged ≥ 18 years who presumed medical cause and were treated by emergency medical services (EMS) in Jiading District. The Data was obtained from Dispatch software system, The emergency case registration system, paper-based treatment records, dispatcher's telephone recording and in-hospital records, This Data organized according to the Utstein template using standard data element definitions. Temporal changes were measured by chi-square trend test. we constructed a multilevel logistic regression model to identify factors independently associated with event survival arrival at hospital and survival to hospital discharge.Results:A total of 1305 patients with OHCA met study inclusion criteria during the study period. Survival to hospital admission was 4.14% increased from 1.87% in 2015 to 7.31% in 2019 for trend ( P=0.009), survival to hospital discharge was 1.23%, increased from 0.37% in 2015 to 3.32% in 2019 ( P=0.003). But there was no evidence of a temporal change in survival to hospital discharge with good neurologic function (0.37 in 2015 to1.33% in 2019, P=0.339 for trend). In the subgroup, the rate of Recognition was increased from 7.49% in 2015 to 19.27% in 2019 ( P< 0.01). The proportion of cases receiving bystander CPR was 17.39%, which increased from 9.36% in 2015 to 25.19% in 2019 ( P= 0.000). The proportion of shockable rhythm was 4.06%, there was no evidence of a temporal change in the proportion of the overall rhythm (3.00%-4.65%, P=0.323 for trend), There were no cases of bystanders using automated external defibrillators (AEDs) in patients with cardiac arrest, The EMS response time (min) were15.45±8.71, which decreased from 15.10±8.12 in 2015 to 13.41±6.47 in 2019 ( P< 0.0001). Multiple regression analysis showed that Male ( OR= 0.315, 95% CI: 0.168-0.519, P =0.000), Not Shockable rhythm ( OR= 0.096, 95% CI: 0.043-0.012, P=0.000), and public location ( OR=2.411, 95% CI: 1.302-4.463, P=0.005) were independent predictor of Factors Associated with survival at hospital admission. Male ( OR= 0.247, 95% CI: 0.070-0.866, P=0.029), Not Shockable rhythm ( OR= 0.072, 95% CI: 0.016-0.318, P=0.001), and No Epinephrine administration ( OR=5.953, 95% CI:1.222-29.012, P=0.005) were independent predictor of Factors Associated with Survival to Hospital Discharge. Conclusions:Survival after OHCA has improved over time. Several targeted initiatives established along the chain of survival of OHCA during the past 5-years may help explain the improvement in survival outcome observed in Jiading District, including improved the rate of Recognition, improved participation rates in bystander CPR and a reduction in EMS response time.In the future, more resources should be improving the quality of CPR training and expanding AEDs coverage and encouraging the public to have the courage to use them.
