Objective To compare the anesthetic effect of atocaine adrenaline injection and lidocaine injec -tion in wisdom tooth extraction .Methods 220 patients with wisdom teeth were selected as the research subjects . According to the random table method ,the patients were randomly divided into research group 110 cases ( a total of wisdom teeth 132,maxillary wisdom teeth 47,mandibular wisdom tooth 85) and the control group 110 cases(a total of wisdom teeth 129,maxillary wisdom teeth 51,mandibular wisdom tooth 78).The research group received atocaine adrenaline injection ,the control group received lidocaine hydrochloride injection .The effects of anesthesia ,VAS score and adverse reactions in the two groups were observed .Results The total effective rate of maxillary wisdom tooth anesthesia in the research group(100.00％) was significantly higher than that in the control group (90.20％),and the difference between the two groups was statistically significant (χ2 =6.358,P<0.05).The total effective rate of mandibular wisdom tooth anesthesia in the research group (100.00％) was significantly higher than that in the control group(92.31％),and the difference between the two groups was statistically significant (χ2 =6.788,P<0.05).The VAS score of maxillary wisdom tooth anesthesia in the research group [(2.57 ±0.65)points]was significantly lower than that in the control group [(2.87 ±0.63) points],and the difference between the two groups was statistically significant(t=2.319,P<0.05).In the control group,there was 1 case of hematoma caused by blood vessels ,and no complications occurred in the research group .Conclusion The anesthetic effects of articaine adrenaline injection in wisdom tooth extraction is better than lidocaine hydrochloride injection , without any complications , it is worthy of clinical promotion .

Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide. However, unlike that in female infertility, the role of CT infection in male infertility remains controversial. The objective of this retrospective study was to explore the impacts of CT infection in the genital tract on sperm quality, sperm acrosin activity, antisperm antibody levels, and inflammation in a large cohort of infertile males in China. A total of 7154 semen samples were collected from infertile male subjects, 416 of whom were CT positive (CT+ group) and 6738 of whom were CT negative (CT- group), in our hospital between January 2016 and December 2018. Routine semen parameters (semen volume, pH, sperm concentration, viability, motility, morphology, etc.), granulocyte elastase levels, antisperm antibody levels, and sperm acrosin activity were compared between the CT+ and CT- groups. Our results showed that CT infection was significantly correlated with an abnormally low semen volume, as well as an increased white blood cell count and granulocyte elastase level (all P < 0.05) in the semen of infertile males; other routine semen parameters were not negatively impacted. The antisperm antibody level and sperm acrosin activity were not affected by CT infection. These findings suggested that CT infection might contribute to inflammation and hypospermia but does not impair sperm viability, motility morphology, and acrosin activity or generate antisperm antibodies in the infertile males of China.
