Helicobacter pylori (H. pylori) is one of the most common pathogens in human and it is closely related to gastrointestinal diseases. It is essential for us to understand the transmission process of H. pylori to prevent its spreading. The oral cavity has been proposed as a reservoir for gastric H. pylori, which has been detected by culture and polymerase chain reaction (PCR) in both dental plaque and saliva. Some researchers have proposed H. pylori in oral cavity may play an important role in its transmission and reinfection. Oral-oral or fecal-oral transmission are thought to be the most possible transmit way. This review will discuss the evidence for the role of the oral cavity in the transmission of H. pylori, the difficulties encountered in addressing this topic and possible directions for future research. Oral H. pylori may also play a role in the diagnosis and prevention of deceases related to H. pylori such as gastritis, gastric ulcer and gastric carcinoma. The recent progresses in this area are also reviewed. Moreover, we also discussed the relationship between oral H. pylori and oral deceases like periodontal disease and oral ulcer.

The average comprehen-sive score of the gel in verification test was 14.8 (RSD=1.35%,n=3). CONCLUSIONS:The optimized formulation of Com-pound tripterygium hypoglaucum gel shows good forming property,the quality meets the requirements.

Eighty six patients with influenza-like diseases were randomly assigned to trial group (n=42,oseltamivir 75 mg,twice daily for 2 days)and control group(n=44,osehamivir 75 mg,twice daily for 5 days).The results showed that there Was no statistical difierence in the duration of fever between trial groups[(56±14)h]and control group[(54±13)h,P=0.623],the cost of the trial group[(193±38)yuan]Was 189 yuan less than that in the control group[(382±61)yuan,P=0.016].It is suggested that the efficacy of two-day course of oseltamivir is the same as that of five-day course in tlle treatment for influenza-like diseases,but with lower cost.

Objective To analyse the multi-slice spiral CT(MSCT) findings of small cholangiocarcinoma of common bile duct.Methods 15 cases with pathologically verified small cholangiocarcinoma of common bile duct were undergone unenhanced and three-phase contrast-enhanced MSCT scan.The entire morphologic changes of common bile duct were analysed with curved planar reformation(CPR).Results The attenuation of tumor relative to pancreas was iso-density in all cases at plain CT scan,hypo-density in 10 cases,iso-density in 3 cases and hyper-density in 2 cases at arterial phase,hypo-density in 1 case,iso-density in 3 cases and hyper-density in 11 cases at portal phase,iso-density in 5 caaes and hyper-density in 10 cases at delayed phase.The focal wall thickening of common bile duct appeared as circular or eccentric in 13 cases,intraluminal nodule in 2 cases,common bile duct was narrowing sharply in 11 cases and ending abruptly in 4 cases at obstructive level.Conclusion The small cholangiocarcinoma of common bile duct is of certain characteristics at unenhanced and three-phase contrast-enhanced CT scan.

Background and purpose:Nowadays, the golden standard of diagnosis for malignant hydrothorax or ascites is exfoliocytology examination, but the missed diagnosis rate is too high. Other methods including immunologic test, telomerase activation test, conjugation of chromosome analysis with cytological examination test, and RT-PCR test. But none of them was widely used due to high cost or high false positive rate. Immunomagnetic beads (IMB) technique is a popular method all over the world in recent years. It was mainly used in isolating and purifying cells, but it was rarely used to detect cancer cells in patients with hydrothorax or ascites so far. Our aim was to fi nd an effi cient way to detect the cancer cells in patients with cancer related hydrothorax or ascites and to improve the corresponding diagnosis rate. Methods:In the experiments, both the traditional exfoliocytology examination method and IMB technique were used to detect the cancer cells in the hydrothorax or the ascites for comparison. Results:Using IMB technique and exfoliocytology method, the positive rates in 30 patients with cancers were 63.3% (19/30) and 23.3% (7/30), respectively, and the false positive rates in 30 patients without cancers were 3.3% (1/30) and 0.0% (0/30), respectively. It could be observed that the positive rate using IMB technique was much higher than that using exfoliocytology method (P0.05). Conclusions:The present study demonstrated that IMB technique is an accurate, sensitive, fast and economic method in detecting the cancer cells in patients with cancer related hydrothorax or ascites, especially for diagnosis and therapy in the early clinical stage. Due to the high effi ciency, IMB technique could be used after exfoliocytology examination to improve the diagnosis rate..

Objective To observe the effects of Jieyu-Chufan capsule(JCC) on the behavior and the monoamine neurotransmitter content of cerebral in depression mouse model and explore its mechanism. Methods The ICR male mouse were randomly divided into seven groups according to their weights(the model group, the low, middle and high doses group, Baiyoujie group, the amitriptyline group, the normal control group). The low, middle and high doses group were given JCC with 1.250, 2.500, 5.000 g/kg separately by intragastric administration. Baiyoujie group was given 0.014 g/kg Baiyoujie by gavage. The amitriptyline group was given 0.050 g/kg amitriptyline by gavage. The model group and the normal control group received the same volume of distilled water intragastrically. The drugs were administrated once a day. The brepharoptosis and movement conditions of mouse were observed after 22 days. The monoamine neurotransmitter content of each group was measured after 25 days. Results Compared to the model group, the number of mouse with brepharoptosis decreased in the high dose group after 1, 2, 6 hour with reserpine injection (P<0.05 or P<0.01);the number of mouse came out from the circle increased after 4 hours with reserpine injection (P<0.05 or P<0.01);the content of NA (880.45 ± 428.81 ng/g, 875.98 ± 449.33 ng/g vs. 299.92 ± 267.08 ng/g) and DA (2 305.99 ± 530.37 ng/g, 2 169.99 ± 278.19 ng/g vs. 1 439.34 ± 357.33 ng/g) in the middle and high dose group increased (P<0.01);the content of 5-HT (781.43 ± 135.10 ng/g vs. 492.01 ± 192.80 ng/g) in the middle group increased (P<0.01). Conclusions JCC showed an antidepression influence in depression mouse model induced by reserpine. The mechanism may be related to regulating the level of monoamine neurotransmitter in the nervous centralis .
