Objective To study the effect of esomeprazole,clarithromycin,metronidazole triple therapy for helicobactor pylori(Hp) infection in children.Methods Ninty-eight cases of children,identified by ~ 13 C-urea breath test(~ 13 C-UBT) Hp infection,deparded into therapy group(66 cases) and control group(32 cases).Therapy group were given Esomeprazole[0.8 mg/(kg?d),1 time/d],clarithromycin[15 mg/(kg?d),2 times/d],metronidazole[30 mg/(kg?d),3 times/d]triple therapy.Control group were given the same treatment except ameprazole.The course was 1 week.They were followed up 4 weeks later after the course and re-tested by ~ 13 C-UBT.Results The recurrent abdominal pain of the two groups recovered in different degrees,and the efficacy rate was 100%.The eradication rate of Hp in therapy group and control group were separately 90.9%(60/66) and 87.5%(28/32).There was no significance difference of the eradication of Hp.Conclusions The trearment of esomeprazole,clarithromycin,metronidazole triple therapy on Hp infection in children is quite effective and safe.The side effect is moderate.

Objective To study the morphologic and pathological characteristics of cat scratch disease(CSD).Methods Eight cases with clinical data and tissue blocks were collected in Guangxi Zhuang Autonomous Region and Hainan Province.The tissues were successively stained by hematox- ylin and eosin,Warthin-Starry(W-S),acid fast and periodic acid-schiff(PAS)methods to study the histopathological changes and pathogens.Results W-S positive Bartonella henselae was the major pathogen of CSD and there was no acid-fast or PAS positive pathogen could be found in the tissues. There were three forms of histological representation as follows:plasmocytoid monocytes(PMO)and monocytoid B-cells(MBC)hyperplasia plus neutrophils immersion in lymphatic sinus(2 cases); MBC rich granuloma and micro-abscess formation(3 cases); starlit abscess with little or no bacteria in the granuloma(3 cases).Conclusions Bartonella henselae mainly transmits through cats.Contact histo- ry with cats and lymphadenectasis suggest the possibility of CSD.The diagnosis can be confirmed by the presence of W-S staining positive bacteria,MBC rich granuloma or micro-abscess and neutrophil reactions in histopathological exam.

Viral hepatitis was the most common infectious disease in china. But the diagnosis and treatment were varied because the viral hepatitis patients were hospitalized in different kinds of hospital such as infectious disease hospital, general hospital and Chinese medical hospital. It was necessary to know clinical characters and information of viral hepatitis patients in different hospitals. The general information, subtype distribution, prognosis, complication, medication and relations of onset with solar term from 41 180 viral hepatitis patients based on HIS data were analyzed. It was found that the age of patients between 18 to 59 years old was most; most patients were males. The national basic medical insurance was the most type of payment. The outcome of viral hepatitis in the youth and female were better than that in the old and male. Acute hepatitis was easer to restore than chronic hepatitis. Liver cirrhosis and hepatocellular carcinoma were the two most complications. The peak of onset was during summer solstice, slight heat and great heat. The most common Chinese medicine was Diammonium glycyrrhizinate and the most common western medicine was reduced glutathione. The combination of D. glycyrrhizinate with reduced glutathione, polyene phosphatidylcholine and thymosin was the main pattern. But It was not knew if the combination of western and Chinese medicine was the most effective therapy to protect liver function. It was necessary to take deeply research of the relationship between the combination therapy and their effectiveness.

OBJECTIVETo study the genetic susceptibility to chemical carcinogens of nasopharyngeal carcinoma (NPC) patients in a high-risk area in Guangxi.

METHODSPCR technique was used to examine the frequency of glutathione S-transferase M1 and T1 gene deletion in a matched case-control study of 91 patients with NPC and 135 control subjects.

RESULTSThe deletion frequency of control subjects was 47.4% (65/135) for GSTM1 and 40.7% (55/135) for GSTT1, whereas that of NPC patients was 61.5% (56/91) for GSTM1 and 59.3% (54/91) for GSTT1 with statistically significant difference between the patients and the controls (P < 0.05 and P < 0.01). Furthermore, the frequency of codeletion of both genes was also higher in NPC patients than the control with statistically significant difference (chi2 = 12.533, P = 0.002).

CONCLUSIONIn high-risk area, nasopharyngeal carcinoma patients and local residents have high frequency of GSTM1 and/or GSTT1 gene deletion. It suggests that a genetic susceptibility to putative chemical carcinogens may be responsible for NPC clustering in the high-risk area studied.

OBJECTIVETo study the association between susceptibility to aflatoxin B1 (AFB1)-related hepatocellular carcinoma(HCC) and the null genotypes of detoxication gene gstM1 and gstT1.

METHODSPeripheral blood white blood cells DNA samples were obtained from all the subjects including 140 HCC cases and 536 controls from AFB1 high risk area Guangxi. gstM1 and gstT1 polymorphisms were detected by polymerase chain reaction technique.

RESULTS(1) gstM1- and gstT1-present were associated with decreasing risk of HCC. gstM1- and gstT1-null were associated with the increasing risk of HCC [adjusted OR (95 % CI) = 2.07 (1.20-3.57) and 1.44 (0.85-2.45), respectively]; (2) The appearance of both gstM1- and gstT1-null genotypes were more susceptible to HCC than either one of them(adjusted OR and 95% CI are 2.43 and (1.19-4.97); (3) From low/median to high level of AFB1 exposure, both gstM1- and gstTl-null genotypes were associated with significantly conspicuous increasing risk of HCC [adjusted OR(95% CI) = 12.76(5.38-30.24) and 7.82(3.61-16.90) respectively].

CONCLUSIONIt was suggested that: genetic polymorphisms of gstM1 and gstT1 were susceptible to HCC; individuals who were gstM1- or gstT1-null would have an increasing risk of developing HCC while individuals with both nulls were more susceptible. There was evidence of interaction between gstM1- and gstT1-null and the level of AFB1 exposure which was associated with the increasing risk of HCC.

OBJECTIVESTo investigate the association between susceptibility to aflatoxin B1(AFB1)-related hepatocellular carcinoma (HCC) and the polymorphism of detoxication gene GSTM1.

METHODSThe peripheral white blood cell DNA samples were obtained from all the subjects including 140 HCC cases and 536 controls from an AFB1 high risk area in Guangxi province. The GSTM1 polymorphism was detected using PCR technique.

RESULTS(1) The GSTM1-present was associated with a decreased HCC risk. The GSTM1-null was associated with an increased HCC risk [adjusted OR (95% CI)= 2.07 (1.20-3.57)]. (2) In the cohorts of both low/median and high exposure levels of AFB1, GSTM1-null genotype was associated with a conspicuous significantly increased risk for HCC [adjusted OR (95% CI) = 1.92 (0.92-4.00) and 1.80 (0.77-4.17)].

CONCLUSIONThe results suggest that genetic polymorphism of GSTM1 was susceptible to HCC and individuals who are GSTM1-null have an increased risk of developing HCC. There is evidence of interaction between GSTM1 polymorphism and AFB1 exposure, especially with low/median degrees of AFB1 exposure.

Abstract: Objective　To analyze the detection of SARS‑CoV‑2 in household environment and public place environment of Huangpu District, and describe the feature of SARS‑CoV‑2 contamination in the environment exposure to the infected cases, so as to support the control strategies such as disinfection and health communication. Methods　The results of RT-PCR test for the environmental samples exposure to the cases infected by SARS‑CoV‑2 during February 1 to March 31 2022 in Huangpu District of Shanghai were collected as the research data. Pearson χ2 was used to test the significance of the differences between positive rates of SARS‑CoV‑2 contamination. Results　From February 1 to March 31, household environment samples had a higher positive rate (6.47%, 234/3 618) of SARS‑CoV‑2 contamination while the public place samples had a lower one (1.22%, 47/3 582) in Huangpu District of Shanghai (χ2=141.908, P<0.01). Among the household buildings, the lane houses of old style representing poorer living condition had the highest positive rates (8.31%, 96/1 155) of SARS‑CoV‑2 contamination while the apartments representing better living condition had the lowest (3.59%, 22/612) (F=5.25，P<0.05). Among the samples from household environment, samples regarding sewerage had the highest positive rates (13.30%,58/436) of SARS‑CoV‑2 contamination, while samples regarding the tool of cooking and sweeping had the lowest (3.10%,17/548) (F=9.84，P<0.01). Among the samples from public place environment, samples regarding entertainment tools had the highest positive rates (13.33%, 2/15) of SARS‑CoV‑2 contamination, while samples regarding the tool of cooking and sweeping had the lowest (0.62%, 4/646) (F=4.22，P<0.01). Conclusion　In the environment exposure to the SARS‑CoV‑2 infected cases, the disinfection, ventilation and cleaning should be intensified strictly. SARS‑CoV‑2's surviving in sewage environment should be evaluation dynamically. More health communication should be pushed to people of poorer living condition.

OBJECTIVETo investigate the relationship between genetic polymorphism in exon 12 C1236T, exon 21 G2677T/A and exon 26 C3435T of the multidrug resistance 1 (MDR1) gene and the risk of childhood acute lymphocytic leukemia (ALL).

METHODA total of 176 patients with ALL and a cohort of 170 matched healthy subjects were included. SNaPshot SNP typing was used to determine the genotypes of MDR1 C1236T, G2677T/A, C3435T. Based on the clinical data, the relationship between genetic polymorphism of MDR1 and the risk of childhood ALL was analyzed.

RESULTThere was significant difference in the distribution of genotype of MDR1 C3435T between the group of controls and cases. The mutant homozygous TT genotype was found to be associated with occurrence of ALL (P = 0.000; OR = 4.504). The data show evidence of pairwise linkage disequilibrium between the three common SNPs (C1236T-G2677T/A-C3435T). The haplotypes of TTT, TGC, CGC and CAC were predominant. The haplotype CGT distributed significantly differently between the groups of controls and cases (P = 0.034). The frequency of the haplotype TTT/TTT in the high risk group was higher than the other groups (P = 0.037).

CONCLUSIONThe present findings suggest that 3435C→T polymorphism in MDR1 gene may be a genetic susceptibility factor for ALL. The haplotype of MDR1 (C1236T-G2677T/A-C3435T) could be the clinical parameter at diagnosis.
