OBJECTIVE:To observe therapeutic efficacy and safety of Compound digestive enzyme capsule in the treatment of dyspepsia. METHODS:154 patients with dyspepsia were selected and randomly divided into observation group and control group, with 77 patients in each group. Control group received routine treatment,Polyzyme tablet 600 mg,tid,30 min after meal;observa-tion group was additionally given Compound digestive enzyme capsule 600 mg,tid,30 min after meal. Treatment course of 2 groups lasted for 2 weeks. The improvement of dyspepsia,clinical efficacy,clinical manifestation score,improvement duration and ADR were observed in 2 groups after treatment. RESULTS:The total effective rate of observation group(89.61%)was significant-ly higher than that of control group(74.03%),with statistical significance(P<0.05). After treatment,the improvement of abdomi-nal distension,early satiety,belching,epigastric discomfort,epigastrium pain,epigastric burning sensation,nausea,vomiting and other clinical digestive symptoms in observation group were significantly better than control group,while clinical symptom score and improvement duration were significantly lower or shorter then control group,with statistical significance(P<0.05). There was no statistically significant difference in the incidence of ADR between observation group (3.90%) and control group (5.19%), with statistical significance (P>0.05). CONCLUSIONS:Compound digestive enzymes capsule has good effect on dyspepsia with less ADR.

Objective To investigate the correlation between atypical respiratory pathogens infection and serum total IgE levels . Methods Serum IgM level was detected in 1 913 blood samples of children with atypical respiratory infection by using indirect im‐munofluorescence assay ,including mycoplasma pneumonia(MP) ,legionella pneumophila (LP) ,rickettsia Q(QFR) ,chlamydia pneu‐monia(CPn) ,adenovirus (Adv) ,respiratory syncytial virus (RSV) ,influenza A virus (IAv) ,influenza B virus (IBv) and parainflu‐enza virus (PIV)1/2/3 .The serum total IgE level was detected by immune scatter turbidimetry .Software SPSS 17 .0 was used in data statistical analysis .Results A total of 991 out of 1 913 samples of respiratory inflected children exhibited positive(positive group) ,while 922 exhibited negative(negative group) in indirect immunofluorescence assay .650 out of the 991 positive samples (65 .59% ) contained MP infection and the combination of MP infection and other virus infections .The serum total IgE level in posi‐tive group was significantly higher than that of the negative group ,and the serum total IgE level in samples with MP infection was higher than that in samples with IBv infection ,Adv infection ,and RSV infection .In the samples in which serum total IgE level was higher than the clinical reference range (100 kU/mL) ,the infection rate of MP infection alone was 31 .29% ,which was evidently higher than that in samples of low IgE level(< 100 kU/mL ,21 .30% ) .On the other hand ,the infection rate of RSV alone was 1 .88% and the infection rate of Adv alone was 3 .13% ,which were both evidently lower than those in samples with normal serum total IgE level(both 6 .53% ) .Conclusion MP is the most common pathogen in children with atypical respiratory pathogen infec‐tion ,and can lead to higher serum total IgE levels .

Objective:To explore the effects of KISS1 gene transfected by lentivirus on the proliferation,invasion and migration abilities of the colorectal cancer HCT116 cells,and to clarify their mechanisms.Methods:The human colorectal cancer cells with the lowest expression level of KISS1 gene were selected.The lentiviral vectors were builted and transfected the KISS1 gene,and the cells were divided into control group (treated with PBS),empty vector group (treated with empty vector) and over-expression group(treated with KISS1 gene vector).The multiplicity of infection (MOI) of the cells was detected by fluorescence microscope.Real-time PCR and Western blotting methods were used to detect the expression levels of KISS1 mRNA and protein(metastin);CCK-8 method was used to detect the proliferation ability of the cells;Transwell chambers method was used to detect the invasion and migration abilities of the cells.Results:Among LoVo,SW620,SW480,HCT-116,and HT29 cells,the expression levels of KISS1 mRNA and protein were lowest in HCT116 cells,so they were chosen as the research carrier.After transfected with lentiviral vectors,the HCT116 cells could stably express the enhanced green fluorescent protein(EGFP) gene,and the MOI was over 80%.Compared with control group and empty vector group,the expression levels of KISS1 mRNA and protein in the cells in over-expression group were significantly increased (P<0.05);the proliferation abilities of the cells in over-expression group were decreased (P<0.05);the invasion ability and migration ability of the cells in over-expression group were decreased (P<0.05).But the differences of proliferation ability,invasion ability and migration ability of the cells between control group and empty vector group were not statistically significant (P>0.05).Conclusion:The KISS1 gene transfected by lentivirus vector can over-express KISS1 protein and inhibit the proliferation,invasion and migration abilities of the colorectal cancer cells,and the mechanism may be related to the expression of KISS1 protein.

Esophagectomy and lymph node dissection are the cornerstones for the treatment of esophageal cancer. Upper mediastinal lymph node dissection is of great value for accurate staging and improving the prognosis of patients. Lymph node dissection along the left recurrent laryngeal nerve is the most challenging procedures in esophageal surgery, and there has been no relevant consensus on the scope and boundary of lymph node dissection. In recent years, with the application of endoscopic technology, especially robotic surgery system in esophagectomy, and the introduction of the concept of superior mediastinal microdissection, the authors have proposed the border of lymph node dissection along the left recurrent laryngeal nerve, so as to achieve precise, radical and standardized dissection. Combined with their own experiences, the authors elaborate on the anatomic boundary, extent and technique of lymph node dissection along the left recurrent laryngeal nerve.
