Objective To investigate the circadian blood pressure(BP)rhythm in hypertensive patients with chronic renal insufficiency.Methods Circadian blood pressure(BP)rhythm was studied by ambulatory 24-h monitoring among hypertensive(n=25,group B)patients with stable progression of chronic renal insufficiency,and among patients with essential hypertension(n=28,group A)without renal disease.Results ①The 24-h diastolic BP and nocturnal systolic and diastolic BP of group B were significantly higher than those of group A[(80.9±13.4)mmHg vs[70.3±15.6)mm Hg,(160.2±17.8)mm Hg vs(140.3+25.9)mm Hg,(82.6±16.1)mm Hg vs(68.8±20.2)mm Hg,P＜0.05)].②Blooa pressure variability(BPV)of 24 hour systolic and diastolic BP of group B was higher than group A[(13.5±3.9)mm Hg vs(11.3±2.1)mm Hg and(9.2±1.2)mm Hg vs(8.3±1.8)mm Hg,P＜0.05).BPV of nocturnal systolic and diastolic BP in group B was signitleantly higher than group A [(14.9±3.3)mm Hg vs(9.3±2.1)mm Hg and (9.7±2.4)mm Hg vs(8.0±2.2)mm Hg,P＜0.01)].③The 24-h profile of BP of group A showed more non-dipper according for 64.3%(18/28),reverse-dipper according for 10.7%(3/28),but which was 40.O%(10/25)and 48.0%(12/25).Conclusion The renal patients show a disturbance in the 24-h profile of BP,higher indexes of noetttrnal BP and a greater nocturnal variability,which may be important factor for event of cardiovascular disease and renal insufficiency.

Objective: To investigate the mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases and trends in probability of premature mortality due to these four chronic diseases in Jiangmen City, Guangdong Province from 2012 to 2021, so as to provide the evidence for perfecting the chronic disease control strategy. Methods: The mortality of malignant tumors, diabetes, cardio-cerebrovascular diseases and chronic respiratory diseases among household registered residents in Jiangmen City from 2012 to 2021 were collected from the Guangdong Provincial Population Death Information Registration Management System, and the crude mortality, standardized mortality by the population of the Fifth National Population Census in China in 2000 and probability of premature mortality were calculated. The trends in mortality and probability of premature mortality were analyzed using average annual percent change (AAPC), and whether achieving the targets for the probability of premature mortality due to four chronic diseases in 2025 and 2030 were evaluated. Results: A total of 226 012 deaths occurred due to four chronic diseases in Jiangmen City from 2012 to 2021, and the overall crude mortality and standardized mortality rates were 569.22/105 and 283.29/105, with a reduction in the probability of premature mortality from 15.04% to 12.05% (AAPC=-2.403%, Z=-7.603, P<0.001). The probability of premature mortality due to four chronic diseases decreased from 19.21% to 16.38% in males, and from 10.42% to 7.58% in females (AAPC=-1.893% and -3.085%, Z=-5.262 and -9.811, both P<0.001). The probability of premature mortality due to diabetes appeared a tendency towards a rise (AAPC=2.317%, Z=2.548, P=0.034), and the probability of premature mortality due to cardio-cerebrovascular diseases showed a tendency towards a decline (AAPC=-4.826%, Z=-13.590, P<0.001), while no significant changing trend was seen in the probability of premature mortality due to malignant tumors or chronic respiratory diseases (AAPC=-0.751% and -2.461%, Z=-1.532 and -1.730, P=0.125 and 0.122). The predicted probability of premature mortality due to four chronic diseases was 10.92% in 2025 and 9.66% in 2030 in Jiangmen City, which were both lower than the target (11.21% and 9.81%). Conclusions The probability of premature mortality due to four chronic diseases appeared a tendency towards a decline in Jiangmen City from 2012 to 2021, which can reach the target in 2025 and 2030. Males should be given a high priority for interventions of chronic diseases, and diabetes control should be reinforced.

Objective To explore the impact of the systematic social skills training on recovery of chronic schizophrenia patients with negative symptom and social skills defects.Methods A total of 82 cases of long -term hospitalized patients with chronic schizophrenia were randomly divided into intervention group and control group by digital table,41 cases in each group.The two groups received psychiatric routine therapy and nursing,and general entertainment therapy,and systemic social skills training was conducted in the intervention group for 12 weeks.PANSS and SSC were respectively used to evaluate the two groups before and after the intervention.Results After 12 weeks of systematic social skills training,the total score of SSC[(24.5 ±4.5)points]in the intervention group was apparently lower than that in the control group[(29.2 ±5.2)points],and the difference was statistically significant(t =3.212, P <0.01).Compared with the control group[(20.5 ±4.3)points,(27.2 ±4.2)points,(59.1 ±9.5)points],in the intervention group the score of negative symptom mental pathology and total score of PANSS were (14.9 ± 3.7)points,(24.5 ±3.5)points,(52.8 ±7.1)points.The differences of total score between the two groups were sta-tistically significant(t =5.199,3.317,3.239,all P <0.01),while the positive symptoms score was not statistically significant(P >0.05).Compared with before intervention,in the negative symptom table,the differences of total score N2,N3,N4,N6 had statistically significant differences(t =4.533,5.413,4.501,4.668,all P <0.01).Conclusion The systematic social skills training can greatly promote chronic schizophrenia patients with negative symptom and social skills defects,improve their social skills and life qualities.

Hepcidin are small cationic peptides with antibacterial activity expressed mainly in the liver of living organisms, and they play important roles in the host's immune response against microbial invasion and regulation of iron metabolism. Thus, they are considered to be good substitutes for traditional antibiotics. It is a good choice that the antimicrobial peptides are prepared by recombinant DNA expression. In the present study, two hepcidin mature peptide cDNAs from channel catfish (Ictalurus punctatus) (mCH) and tilapia (Oreochromis niloticus) (mTH) were connected by SOE-PCR in order to obtain more recombinant hepcidin with broad antimicrobial spectrum, and EcoR I and Not I sites were added to 5'- and 3'- ends of the fragment, respectively. The recombinant eukaryotic expression vector "pPIC9K-mCH-mTH" was successfully constructed, and transformed into Pichia pastoris GS115. The transformants containing multicopy gene insertion were selected by using different concentrations of G418 and other specific mediums, and identified by PCR for yeast genomic DNA. Expression was induced by adding 1% methanol at 30 degrees C for different times. Tricine-SDS-PAGE analysis demonstrated that the most appropriate expression time was 72 h, at which a high expression yield (77 mg/L) for the target protein was exhibited. The highly purified target protein was obtained from the fermentation supernatant by SP-Sepharose cation exchange chromatography. Bacteriostatic activity assay demonstrated that the fermentation supernatant containing the target protein and purified recombinant target protein had bacteriostatic activities against gram-positive and gram-negative bacterium. The present result provides the important initial value for industrial production of hepcidin antimicrobial peptide.

Objective To investigate the acute toxicity and anti-stress effects of Naoxinshu capsule (NC) in mice.Methods In acute toxicity experiment,mice were oral administered to determine the maximum tolerance dose of NC.In anti-stress experiments,mice were divided into 5 groups at random,namely NC high,medium and low dose groups (2.4,1.2 and 0.6 g/kg,respectively),Gypenosides group(0.75 g/kg) and control group (n=10).After seven days of oral administration,rope climbing time,loaded swimming time,anti-hypoxia time,and survival rate under high or low temperature tests were carried out,respectively.Results The maximum tolerance dose of NC was 72 g/kg.NC high,medium and low dose groups significantly prolonged the rope climbing time [is (9.5 ± 3.1) min,(6.0± 1.6) min,(4.1 ± 1.2) min],loaded swimming time [is (28.2± 6.8) min,(25.7± 10.3)min,(22.9± 8.0)min] and anti-hypoxia time (around 17 min),compared to the control group (P＜0.05 or P＜0.01).NC high dose group significantly improved the survival rate of mice (i.e.30％) under high or low temperature (P＜0.05).Conclusion NC shows good anti-stress effects,and no detectable acute toxicity in mice.

AIM: To observe the growthinhibiting cell cycle-modifying and apoptosis-inducing effects of satraplatin on human ovarian carcinoma cell line A2780, and to explore its possible mechanism. METHODS: The effect of satraplatin on A2780 cells proliferation was determined using MTT, and the change in cell cycle was analyzed using PI staining. Morphologic change was visualized by fluorescence and electron microscopy. AnnexinV-FITC/PI staining multiparameter flow cytometry and immuno- histochemical TUNEL assay were used to detect apoptotic cells. The activity of caspase-3 and the effect of pan-caspase inhibitor on cell viability were measured as well. RESULTS: The growthinhibiting and apoptosis-inducing effects of satraplatin were dose-dependent and similar to those of cisplatin. Satraplatin mainly caused A2780 cell accumulation in S phase accompanied by minor accumulation in G2/M phase. Cells treated with satraplatin exhibited typical morphology of apoptosis. Satraplatin-induced increase in caspase-3 activity of A2780 cells was concentration-dependent. The viability of A2780 cells was affected by pan-caspase inhibitor z-VAD-fmk in a dose-dependent manner under certain concentration of z-VAD-fmk. CONCLUSION: Satraplatin-induced apoptosis in A2780 in vitro was observed. Caspase-dependent and independent pathways were involved in apoptosis induced by satraplatin, and the latter included caspase-3 dependent and non-caspase-3 dependent pathways.
