A high incidence of esophageal cancer exists in China. Surgical resection remains the dominant therapeutic intervention for patients with operable esophageal carcinoma. However, alternative strategies are actively applied to reduce the frequency of post-op-erative local or distant disease recurrence and to prolong survival. These strategies include neoadjuvant and adjuvant therapies. This review discusses the current knowledge, as well as available data and information, with regard to neoadjuvant and adjuvant therapies for patients with locally advanced esophageal cancer.

As an important mediator of allergic inflammation, mast cell tryptase is involved in the induction of hypersensitivity, infiltration of inflammatory cells and tissue remodeling in respiratory tract. The effects of tryptase inhibitors on the actions of tryptase show further the potential of tryptase in the pathogenesis of asthma and its inhibitors in the treatment of asthma.

Methods According to HAART regimens ,102 HIV/AIDS patients were divided into two groups :D4T group(D4T+3TC+NVP) and AZT group(AZT+3TC+ NVP) .Blood lipids(TG ,TC ,LDL-C and HDL-C)at baseline ,24 weeks and 48 weeks after HAART were detected .Results Compared with paired t test ,TG ,TC and LDL-C at 24 weeks follow-up of the patients in D4T group were significantly higher than at baseline(P<0 .05) ,and TC at 48 weeks follow-up were still higher than at baseline(P<0 .05) .TG and TC at 24 weeks follow-up of patients in AZT group were significantly higher than at baseline(P<0 .05) .There were no significant difference at blood lipid between the two groups(P>0 .05) .Conclusion There are dyslipidemia of the patients with HIV/AIDS u-sing D4T-based and AZT-based regimens ,and the dyslipidemia are increase of TC and TG ,these increase is border higher .TG and TC at 24 weeks follow-up of the HIV/AIDS patients using D4T-based regimen are increased early ,and TC are still at higher level .

Objective To encode the protein cystatin M with CST6 gene and construct a CST6-overexpression vector,and transfect it into the gastric cancer cells SGC-7901 in order to observe the effect of cystatin M on the proliferation and migration abilities of SGC-7901 cells.Methods There were three groups in the experiment:pcDNA3.1(+)-CST6 group,pcDNA3.1 (+)group and non-transfected group.RT-PCR and Western blot were used to identify the RNA expression of CST6 in SGC-7901/CST6 cells.The proliferation and migration abilities of the transfected cells were detected by MTT and cell wound healing assay,respectively.Results SGC-7901/CST6 cells stably expressed CST6 gene RNA and cystatin M protein.The proliferation and migration of pcDNA3 .1 (+)-CST6 group cells were reduced compared with those of cells in the other two groups (P<0.05).Conclusion Cystatin M can inhibit the proliferation and migration of SGC-7901 cells.

Objective:To investigate the status of family function of patients after hysterectomy, explore the effect of self-concealment on family function.Methods:From January to November 2021,the 177 patients after hysterectomy in Guangdong Provincial People ′s Hospital were investigated by General Data Questionnaire, Family APGAR Indexand Self-Concealment Scale (SCS), and the influencing factors of family function were analyzed by univariate analysis and binary logistic regression. Results:The total score of APGAR and SCS was 9.00 (6.50, 10.00) and 24.00 (17.00, 33.00) after hysterectomy. Univariate analysis showed that marital status, working conditions and tendency of self-concealment were the influencing factors of family function. In the regression analysis of binary Logistic, tendency of self-concealment( P<0.01) and marital status ( P<0.01) entered the regression equation. Conclusions:The family function of patients after hysterectomy is generally good, and self-concealment is a risk factor. It is suggested that in clinical work, attention should be paid to the tendency of self-concealment in patients after hysterectomy, and targeted intervention measures should be taken to improve their family function.

Objective:To explore the current level of knowledge, attitude and practice of rehabilitation for postpartum diastasis recti abdominis inpuerperae, and analysis the influencing factors of behavior, in order to provide a reference frame for nursing staff to formulate effective health education programs.Methods:From November 2020 to April 2021, a self-designed questionnaire was used to investigate 522 puerperae from 4 tertiary hospitals in Guangdong province, Jiangsu province and Zhejiang province, to explore their level of knowledge, attitude and behavior of rehabilitation for postpartum diastasis recti abdominis. Mann-Whitney Utest or Kruskal-Wallis Htest was used for univariate analysis, Binary Logistic regression analysis was used to analysis the influencing factors of rehabilitative behavior.Results:The median score of knowledgedimension, attitude dimension and behavior dimension of rehabilitation for postpartum diastaisis recti abdominis in puerperae respectively were 47.0 (36.0, 55.0), 26.0 (24.0, 31.0), 15.0 (10.0, 18.0) points. The results show that the main factors influencing of rehabilitation behaviorfor postpartum diastaisis recti abdominis in puerperae were knowledge ( χ2 = 87.78, P<0.05), attitude ( χ2 = 4.77, P<0.05), number of deliveries ( χ2 = 3.94, P<0.05) and family personal monthly income ( χ2 = 4.88, P<0.05). Conclusions:At present, puerperae have a positive attitude towards rehabilitation for postpartum diastasis recti abdominis, but the level of knowledge and practice of rehabilitation for postpartum diastasis recti abdominisneed to be improved.Nursing staff should focus on puerperae with incomplete knowledge, negative attitude, multiple deliveries and low family personal monthly income.

C1q nephropathy is a special type of glomerulonephritis, which characterized by massive deposition of C1q on glomerular mesangial.The pathological manifestations of C1q nephropathy are minimal change disease, focal segmental glomerulosclerosis and proliferative glomerulonephritis.C1q nephropathy is prone to hormone dependence or resistance, and the prognosis is not good relatively.The pathogenesis of the disease is not clear.The clinical manifestations are quite different.Glucocorticoid is still the first choice for treatment.Immunosuppressive agents are often used in patients with hormone dependence or resistance.It has been found that the rituximab has good curative effect on C1q nephropathy in recent years.Although the understanding and research on C1q nephropathy is deepening, there is still much controversy about whether to classify C1q nephropathy into a class of independent diseases and the clinical significance of their classification.In this paper, the pathogenesis, pathological histology, clinical characteristics, treatment and prognosis of C1q nephropathy are reviewed in order to have a better understanding of C1q nephropathy.
