BACKGROUNDTo evaluate the efficacy and toxicity of ITP (ifosfamide + perarubicin + cisplatin) and NP (vinorelbine + cisplatin) regimens in the treatment of advanced non small cell lung cancer (NSCLC).

METHODSOne hundred inoperatable or recurrent patients with stage III and IV NSCLC were randomized into ITP group and NP group treated by the two regimens responsively for 2 or 3 cycles.

RESULTSThe overall response rate was 51.5% for ITP group and 50.9% for the NP group, respectively. There was no statistically significant difference of the overall response rate between the two groups ( P > 0.05). The major side effects were leukopenia and gastrointestinal reaction. The leukopenia incidence was higher in ITP group than that in NC group ( P < 0.05).

CONCLUSIONSBoth ITP and NP regimens are effective for the advanced NSCLC. Compared with ITP regimen, NP regimen has less bone marrow toxicity than ITP regimen.

Objective To study the effect of high quality nursing service on independent living ability and psychological status of post-stroke depression patients.Methods A total of 130 postdepression patients were randomly divided into observation group and control group.The observation group received high quality nursing service and control group received routine nursing.The scores of activity of daily living scale(ADL) and Hamilton depression scale (HAMD) were used to assess the curative effect before and after intervention in two groups.Results Compared with intervention before,the scores of ADL and HAMD in two groups were both decreased after intervention (P ＜ 0.05),but the observation group had lower scores than control group (P ＜ 0.05).Conclusion High quality nursing service can effectively improve independent living ability and relieve the feelings of depression in post-stroke depression patients.

OBJECTIVETo explore whether the vitamin D receptor gene (VDR) polymorphisms are associated with the outcomes of hepatitis B virus (HBV) infection in Chinese Han population.

METHODSPolymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the polymorphisms of Fok I locus in exon 2 and Taq I locus in exon 9 of VDR gene. One hundred and eighty-four chronic hepatitis B patients and 205 asymptomatic HBV carriers were recruited to make the comparison of frequencies of genotype and haplotype of the VDR gene between the patients and the carriers.

RESULTSThe univariate analysis showed a significant difference in Fok I polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group. The FF genotype frequency in chronic hepatitis B patients group was 44.6%,higher than 31.7% in asymptomatic HBV carriers group (P<0.05). After adjusting the confounders by multiple logistic regression analysis, the result still showed a significant difference in Fok I site polymorphism between chronic hepatitis B patients group and asymptomatic HBV carriers group (OR=1.95, P<0.05). The FT haplotype frequency in chronic hepatitis B patients group was higher than that in asymptomatic HBV carriers group (OR=1.45, P<0.05). The fT haplotype frequency in chronic hepatitis B patients group was lower than that in asymptomatic HBV carriers group (OR=0.72, P<0.05).

CONCLUSIONVDR gene polymorphism may be an influence factor of genetic susceptibility to HBV infection.

To establish a method for simultaneous determination of the contents of sesamoside, menthyl chloride, chlorogenic acid, caffeic acid, 8-O-acetyl-phloridzin methyl ester, forsythiaside B, luteolin, and ergosterol, the LIPLC analysis was performed on a Kinetex XB-C₁₈ (4.6 mm×50 mm,2.6 μm)column with acetonitrile (A)-0.1% phosphoric acid solution (B) as the mobile phase. The flow rate is 1.0 mL min⁻¹. The detection wavelength was 238, 320 and 350 nm and column temperature was 30 ℃. The results showed that the eight components could be completely separated with good linear relationships (r≥0.999 8) in the linear range. The average recoveries were 96.61%-100.4%. The method was simple with strong specificity and high precision. It can be used for the identification and quality evaluation of the Lamiophlomis rotate.The results also showed that there was a correlation between the various components, and the habitat was the main factor affecting the content of the eight components. However, the degradation gradient had no obvious effect on the contents, while the content of sesamoside was significantly decreased after one year of storage.

Objective This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength. Methods We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.Results In the multimetal linear regression, Cu (β=-2.119), As (β=-1.318), Sr (β=-2.480), Ba (β=0.781), Fe (β= 1.130) and Mn (β=-0.404) were significantly correlated with grip strength (P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95％ confidence interval:-1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn (Pinteractions of 0.003 and 0.018, respectively).Conclusion In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

OBJECTIVE: To observe the changes of symptoms, Chinese medicine (CM) syndrome, and lung inflammation absorption during convalescence in patients with coronavirus disease 2019 (COVID-19) who had not totally recovered after hospital discharge and whether CM could promote the improvement process. METHODS: This study was designed as a prospective cohort and nested case-control study. A total of 96 eligible patients with COVID-19 in convalescence were enrolled from Beijing Youan Hospital and Beijing Huimin Hospital and followed up from the hospital discharged day. Patients were divided into the CM (64 cases) and the control groups (32 cases) based on the treatment with or without CM and followed up at 14, 28, 56, and 84 days after discharge. In the CM group, patients received the 28-day CM treatment according to two types of CM syndrome. Improvements in clinical symptoms, CM syndrome, and absorption of lung inflammation were observed. RESULTS: All the 96 patients completed the 84-day follow-up from January 21 to March 28, 2020. By the 84th day of follow-up, respiratory symptoms were less than 5%. There was no significant difference in the improvement rates of symptoms, including fatigue, sputum, cough, dry throat, thirst, and upset, between the two groups (P>0.05). Totally 82 patients (85.42%) showed complete lung inflammation absorption at the 84-day follow-up. On day 14, the CM group had a significantly higher absorption rate than the control group (P<0.05) and the relative risk of absorption for CM vs. control group was 3.029 (95% confidence interval: 1.026-8.940). The proportions of CM syndrome types changed with time prolonging: the proportion of the pathogen residue syndrome gradually decreased, and the proportion of both qi and yin deficiency syndrome gradually increased. CONCLUSIONS Patients with COVID-19 in convalescence had symptoms and lung inflammation after hospital discharge and recovered with time prolonging. CM could improve lung inflammation for early recovery. The types of CM syndrome can be transformed with time prolonging. (Registration No. ChiCTR2000029430).

Objective: To summarize the clinical characteristics of inflammasomopathies, enhance the recognition of those diseases, and help to establish the early diagnosis. Methods: The clinical manifestations including fever, rash, systems involvement as well as laboratory results and genotypic characteristics of 35 children with inflammasomopathies diagnosed by the Department of Pediatrics, Peking Union Medical College Hospital, from January 1, 2008 to December 31, 2020 were analyzed retrospectively. Results: A total of 35 cases of inflammasomopathies were diagnosed, and 20 of them were boys while 15 were girls. Inflammasomopathies patients have early onset, the age of onset as well as diagnostic age were 1 (0,7) and 7 (3,12), respectively. Among those patients, 10 had familial mediterranean fever, 3 had mevalonate kinase deficiency, 15 cases had NLRP3 gene associated autoinflammatory disease, 4 cases had NLRP12-associated autoinflammatory disease, 2 cases had familial cold autoinflammatory syndrome 3, and 1 case had familial cold autoinflammatory syndrome 4. A total of 34 cases (97%) showed recurrent fever, 27 cases (77%) had skin rashes, while 11 cases (31%), 10 cases (29%), and 8 cases (23%) were presented with lymphadenopathy, hepatosplenomegaly and growth retardation, respectively. In terms of systemic involvement, there were 18 cases (51%), 12 cases (34%), 8 cases (23%), and 5 cases (14%) with skeletal, neurological, auditory, and renal involvement, respectively. Central nervous system involvement was seen only in NLRP3 gene associtated autoinflammatory diseases (12 cases), sensorineural deafness was seen in NLRP3 gene associtated autoinflammatory diseases (6 cases) and NLRP12 gene associated autoinflammatory diseases (2 cases), and abdominal pain was observed in familial Mediterranean fever (5 cases), mevalonate kinase deficiency (1 case) and NLRP12 gene related autoinflammatory diseases (1 case). In the acute inflammatory phase, the acute phase reactants (erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)) of 35 cases (100%) were significantly increased. There were 21 cases received ferritin examination, and only 4 cases (19%) showed an increase of it. In terms of autoantibodies, among all 35 patients, 4 cases (11%) were positive for antinuclear antibodies (ANA). Conclusions: Fever, skin rash, and skeletal manifestations are the most common clinical features, accompanied with increased CRP and ESR, and negative results of autoantibodies such as ANA. The clinical manifestations of those diseases are complex and diverse, and it is prone to delayed diagnosis and treatment.
