Objective To explore the therapy measurement of iron deficiency anemia(IDA)associated helicobacter pylori(HP)infection among children.Methods Eight hundred and ninty nine cases entrusted children aged from 2 to 7 years old were measured hemoglobin(Hb),mean corpuscular volume(MCV)mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and serum ferri,serum fettin(SF),HP-IgG antibodies.Divided the HP-IgG positive cases into two groups for treatment,The treatment group adopted omeprazole,amoxicillin and metronidazole to cure them for two weeks,then oral ferrous sulfate sugar liquid.The contrast group purely take the ferrous sulfate sugar liquid.After eight weeks re-examined the Hb and SF.Results Totally 279 cases were diagnosed as Hp-positive,620 as HP-negative and 99 children diagnosed as IDA,among the 99 cases IDA,58 cases with HP infection(20.8%) and 41 cases with non-HP infection(6.7%).That means the number of IDA cases with HP infection was higher than those with non-HP infection(?2=39.46 P

Objective:To investigate the efficacy of antiviral therapy and its selection in hospitalized children with infectious mononucleosis (IM).Methods:The IM children admitted to Shenzhen Children’s Hospital from January 2017 to December 2021 were divided into acyclovir (ACV) treatment group and non-antiviral treatment group, and the clinical data were collected for retrospective analysis.Results:A total of 370 children were included, the median age was 3.6 years, each age group proportion: <3 years (25.9%), 3-<6 years (53.0%). 6-<10 years (17.6%) and ≥10 years (3.5%). Male∶Female=1.5∶1. While 42.4% (157/370) of the 370 children received ACV, 57.6% (213/370) did not receive antiviral therapy; 52 cases were treated in infectious disease department, and none of them received antiviral treatment, and 318 cases were treated in non-infectious disease department, of which 157 cases were in ACV group. There was significant difference between the two groups ( P <0.001); Thirty-eight cases of children in non-infectious disease department complicated with abnormal liver function, of which 23 cases (60.5%) were in the ACV group and 15 cases (39.5%) were in the non-antiviral treatment group. There was no significant difference between the two groups ( P=0.060). Compared with the non-antiviral treatment group, the ACV group has longer hospitalization days and higher hospitalization expenses ( P<0.01). There was no significant difference in duration of fever ( P>0.05). The number of atypical lymphocytes recovered faster in ACV group ( P=0.001). Conclusions:The hospitalized children with IM were mostly boys, and most of them were from 3 to 6 years old. ACV treatment could not shorten the duration of fever and hospitalization days of IM children, nor could it reduce the hospitalization expenses. Abnormal liver function did not affect the decision of antiviral treatment, and infectious disease specialists prefer not to use antiviral drugs. The authors advocate reducing the use of antiviral drugs for IM.

OBJECTIVETo study the short- and long-term results for acute deep vein thrombosis (DVT) of the lower extremity treated by surgical thrombectomy and interventional thrombectomy.

METHODSOne hundred and thirty-six acute DVT cases treated by surgical thrombectomy or interventional thrombectomy from March 2000 to August 2008 were reviewed. There were 80 patients treated by surgical thrombectomy. Among them, 30 cases were male, 50 cases were female, aged from 26 to 81 years with a mean of (58 ± 14) years. The other 56 cases were treated by interventional thrombectomy. Among them, 25 cases were male, 31 cases were female, aged from 22 to 92 years with a mean of (57 ± 17) years. All the 136 patients received district anticoagulation with heparin and thrombolysis with urokinase after operation.

RESULTSAfter operation, the circumference difference between bilateral thigh in intervention group were less than that in surgical group [(0.8 ± 1.3) cm vs. (1.5 ± 1.7) cm, P = 0.002]. The circumference difference of bilateral calf had no significant difference [(0.7 ± 1.1) cm vs. (1.0 ± 1.1) cm, P = 0.152]. The average hospital stay in intervention group was shorter than that in surgical group [(7 ± 4) d vs. (15 ± 7) d, P = 0.000]. The morbidity of complications in intervention group was less than that in surgical group (8.9% vs. 32.5%, P = 0.000). One hundred and eight patients were followed up, who was 79.4% of the total patients, and were followed up for an average of (46 ± 29) months. The circumference difference of thigh and calf, the symptom grade, the pigmentation, varicose veins, intermittent claudication and ulceration between the two groups had no significant difference (P > 0.05).

CONCLUSIONCompared with surgical group, intervention group has a better short-term effect, shorter hospital stays, less complications and similar long-term result.
