Most of the patients who suffer from secondary iron overloading are transfusion-dependent.Excess iron deposits in the important organs will have notable effect on survival.The serum ferritin can not reflect the iron stores in the specific organ rigorously.There are two noninvasive techniques that can assess tissue iron:superconducting quantum interface device and MRI-T2*.The patients who are transfusion-dependent should monitor the body iron stores and chelate the iron in time.Now the drugs for iron chelation therapy include deferoxamine,deferiprone and deferasirox.

OBJECTIVE:To investigate mycoplasma infection and drug susceptibility in patients with non-gonococcus urethritis (NGU),and to provide reference for rational use of antibotics in patients with mycoplasma infection.METHODS:Mycoplasma diagnosis reagent box was used to culture and identify mycoplasma from suspected patients with NGU,and to conduct drug sensitivity test.RESULTS:360 cases of positive mycoplasma among 711 suspected NGU patients (positive rate was 50.66%),Uu positive were 235 cases (positive rate 33.05%);Mh positive were 30 cases (positive rate 4.22%);Uu+Mh positive were 95 cases (positive rate 13.36%).Results of drug sensitivity test showed josamycin,doxycycline,minocycline,clarithromycin and tetracycline were best choice for Uu single infection,and josamycin,doxycycline,minocycline for Uu+Mh infection.CONCLUSION:Uregenital tract infections are mainly caused by Uu.Clinical medication for mycoplasma infection should be in accordance with the type of mycoplasma and results of drug sensitivity test.

OBJECTIVE: To facilitate separate-store management and cold-chain management for hospital drugs. METHODS: The temperature division of separate-store management of hospital drugs was analyzed. The cold-chain management of cold-storage and freeze-storage drugs was discussed. RESULTS & CONCLUSIONS: During the storage period of hospital drugs,the temperature of cold-storeroom should be kept at 2～8 ℃,that of shady and cool storeroom at 0～20 ℃,and that of the normal temperature storeroom at 0～30 ℃. In the cold-chain management,great importance should be attached to several key steps such as to standardize the transport vehicles,set up stores for the turnover of drugs,and to clarify the operational procedure and working standard. It is necessary to strengthen separate-storehouse management and cold-chain management for hospital drugs.

Objective: To investigate the trends in incidence and mortality of stroke in Ningbo City, Zhejiang Province from 2012 to 2021, so as to provide the evidence for improving the stroke control strategy in Ningbo City. Methods: Data pertaining to the stroke incidence and mortality in Ningbo City from 2012 to 2021 were captured from Ningbo Municipal Chronic Disease Collaborative Management System, and the incidence and mortality of stroke was estimated and standardized by the Sixth National Population Census in 2010. The trends in incidence and mortality of stroke were evaluated using annual percent change (APC) in Ningbo City from 2012 to 2021. Results: A total of 185 747 residents with stroke were reported in Ningbo City from 2012 to 2021. The crude incidence of stroke was 312.78/105 in Ningbo City from 2012 to 2021, which appeared a tendency towards a rise (APC=2.429%, t=5.507, P<0.001), and the standardized incidence of stroke was 188.86/105, with no remarkable changes seen (APC=-0.399%, t=-1.544, P=0.161). There were 47 355 deaths due to stroke in Ningbo City from 2012 to 2021, and the crude and standardized mortality rates were 79.74/105 and 42.79/105, which both appeared a tendency towards a decline (APC=-4.778%, t=-6.867, P<0.001; APC=-8.269%, t=-13.729, P<0.001). Higher standardized incidence and mortality were seen among men (226.05/105 and 50.14/105) than among women (153.37/105 and 35.89/105), and the crude incidence and mortality of stroke appeared a tendency towards a rise with age (χ2trend=3 671.325, 1 419.107, both P<0.001). The standardized incidence and mortality of hemorrhagic stroke were 40.38/105 and 18.56/105, both showing a tendency towards a decline (APC=-5.042%, t=-12.958, P<0.001; APC=-11.570%, t=-14.979, P<0.001), and the standardized incidence of ischemic stroke was 143.91/105, appearing a tendency towards a rise (APC=1.254%, t=3.223, P=0.012), while the standardized mortality of ischemic stroke was 19.65/105, with no obvious changes seen (APC=-2.110%, t=-2.150, P=0.064). Conclusions The incidence of stroke appeared a tendency towards a rise and the mortality appeared a tendency towards a decline in Ningbo City from 2012 to 2021. Men and the elderly are at high risk of stroke.

Objective To evaluate the optimized efficacy of thoracic paravertebral block (TPVB) combined with general anesthesia via the research on the postoperative cellular immune function in the patients undergoing radical resection for esophageal cancer.Methods Forty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients of both sexes,aged 45-64 yr,with body mass index of 20-25 kg/m2,scheduled for elective radical resection for esophageal cancer,were divided into 2 groups (n =20 each) using a random number table:general anesthesia group (G group) and TPVB combined with general anesthesia group (TPVB+G group).In group TPVB+G,TPVB was performed at T4 and T6 on the operated side under ultrasound guidance with 0.5％ ropivacaine 15 ml before anesthesia induction.Anesthesia induction was started after the level of block was confirmed.Anesthesia was maintained with propofol given by target-controlled infusion at the target plasma concentration of 1-4 μg/ml,and bispectral index value was maintained at 40-50.Patient-controlled intravenous analgesia was performed after operation,and visual analog scale score was maintained ≤ 3.Before anesthesia induction,at the end of operation and at 24 and 48 h after operation,blood samples were collected from the central vein for determination of the levels of T lymphocyte subsets CD3+,CD4+ and CD8+ and CD4+/CD8+ ratio.Ricker Sedation-Agitation Scale scores were recorded at 10 min,20 min,30 min and 1 h after extubation and 6,24 and 48 h after operation.The consumption of intraoperative remifentanil,requirement for vasoactive agents during recovery from anesthesia,the number of unsuccessfully delivered doses and the total number of attempts were also recorded.Results Compared with group G,Ricker Sedation-Agitation Scale scores were significantly decreased at 10 min after extubation,the consumption of intraoperative remifentanil,requirement for vasoactive agents during recovery from anesthesia and the number of unsuccessfully delivered doses were decreased,and the postoperative CD4+ level and CD4 +/CD8 + ratio were increased in group TPVB+G (P＜0.05).Conclusion TPVB combined with general anesthesia can improve the postoperative cellular immune function and is an optimal anesthesia regimen in the patients undergoing radical resection for esophageal cancer.

Objective To explore the difference in the effect of isoflurane inhalation on long-term cognitive function between male and female rate.Methods Forty-two SD rats (22 female, 20 male) that exhibited normal spontaneous activity and behaved normally in passive avoidance and Morris water maze tests were used in this study. They were divided into 2 sex groups:group female (group F) and group male (group M). Each group was further divided into 2 subgroups: control subgroup (Fc, Mc groups) and isoflurane group (Fs, Ms groups). The animals were anesthetized with 3 % isoflurane in O2 for 2 h in the 2 study subgroups, while the control subgroups inhaled O2 for 2 h. The spontaneous activity test was performed at 1, 30, 60 and 90 d, while the passive avoidance task was performed at 2, 30, 60 and 90 d after isoflurane anesthesia. Morris water maze test was performed for 5 consecutive days at 3-7 d, 31-35 d, 61-65 d, and 91-95 d after isoflurane anesthesia.Results In spontaneous activity test the total distance and the speed were significantly decreased at 1 d after isoflurane anesthesia in both Fs and Ms subgroups as compared with Fc and Mc subgroups. There was no significant difference in the number of error and latency after isoflurane anesthesia compared with the control subgroups in both male and female rats in the passive avoidance task. In Morris water maze test the escape latency and swimming distance were significantly prolonged at 1 and 31 d after isoflurane anesthesia as compared with control subgroup in female rats and at 3-6d, 31-34 d and 61 d after isoflurane anesthesia as compared with control subgroup in male rats, and were significantly longer after isoflurane anesthesia in male than in female rats. Conclusion Two hour 3.0% isoflurane anesthesia can impair long-term cognitive function and the impairment is greater in male than in female rats.
