Objective To investigate the expression of the cyclin D1 in pubertal mammary hypertrophy and micromastia. Methods The expression of cyclin D1 was detected by SP immunohisto-chemistry in 18 cases of pubertal mammary hypertrophy and 12 cases of micromastia. Results The expression rate of cyclin D1 within breast tissue was 83. 33 % and 16. 67 % in pubertal mammary hypertrophy and micromastia, respectively. There was significant difference between the two groups (P<0. 01). Conclusion The expression level of the cyclin D1 within breast tissue in pubertal mammary hypertrophy is higher than that in micromastia.

OBJECTIVE To choose the marks of screening HBV infective source during surgical operation.METHODS On the basis of the HBV infective threshold value,HBV infective source and HBV susceptibility among the surgeons,to choose the marks of screening HBV infective source during surgical operation.RESULTS Before the immunization of surgeons against HBV,the ratio of HBV infective source between HBsAg positive and HBeAg positive carriers was 19.2% and 83.9%,respectively.That of HBsAg negative and HBeAg negative carriers was 0 and 3.2%.The sensitivity of screening HBV infective source with HBsAg acting as mark was much higher than HBeAg.The specificity was lower than HBeAg.After the immunization of surgeons against HBV,the ratio of HBV infective source between HBsAg positive and HBeAg positive carriers was 0.6% and 3.2%,respectively.None of the negative one was HBV infective source during surgical operation.The sensitivity of screening HBV infective source with HBeAg acting as mark was the same as HBsAg.But the specificity was remarkably higher than HBsAg.CONCLUSIONS Before the immunization of surgeons against HBV,HBsAg acting as the screening mark of HBV infective source during surgical operation is more suitable.After that HBeAg is more suitable.

OBJECTIVE To investigate the characteristics of hypopharyngeal carcinoma detected by narrow band imaging(NBI)endoscopy and evaluate the value of NBI in the early diagnosis of hypopharyngeal carcinoma. METHODS Between December 2008 and July 2009,a total of 46 consecutive patients with hypopharyngeal squamous cell carcinoma were enrolled in this study. High performance endoscopic system equipped with the white light mode and NBI mode was introduced in the examination of pharynx and larynx. The quality of visualization of morphologies of epithelial capillary and demarcation line of each lesion under NBI view was evaluated in comparison with conventional white light endoscopy. RESULTS Among the 46 patients,a total of 86 lesions were detected. The notable characteristic of hypopharyngeal squamous cell carcinoma is the well demarcated brownish area and scattered brown dots. The NBI laryngoscope could provide better visualization of morphologies of epithelial capillary and demarcation line in superficial carcinoma of hypopharynx than the white light mode(P

In October 2017, a female patient, 3 years and 5 months of age, with Crouzon syndrome, associated with multiple craniosynostoses was admitted to Plastic Surgery Hospital. Combined intracranial and extracranial approaches of fronto-orbital advancement and cranial suture release were performed to treat plagiocephaly and scaphocephaly. The patient′s families were investigated. Corresponding mutations were detected by DNA sequencing. Therapeutic effect was satisfactory. The mutation was inherited for 5 generations. Genomic sequencing results showed that the exons of fibroblast growth factor receptor 2 gene in the child was mutated, which excessively activated downstream signals and caused craniosynostosis.

Objective To discuss a surgical treatment to correct prominent mandibular angle with long chin.Methods From July 2015 to October 2017,21 patients with malocclusion who suffered from prominent mandibular angle with long chin underwent en-bloc mandibular U-shaped osteotomy through oralincision in order to shorten mandibular angle,the body of mandible and the chin and to improve the facial contour.We assessed the surgical effect through comparison of radiologic images,satisfaction of patients and surgical complications between pre-operation and post-operation.Results In this group,all oral incisions had healing by first intention,without hematoma,infection and osteonecrosis.Low lip numbness occurred in 16 patients.After following up for 6-12 months,the lower lip numbness was recovered in 14 patients and relieved in 2 patients.All patients satisfied with the appearance after the operation.Conclusions En-bloc mandibular U-shaped osteotomy is an improvement for mandible surgery treatment.Its osteotomy line involves the whole mandible,which makes the length and width of mandible smaller apparently.This procedure can effectively correct prominent mandibular angle with long chin.

OBJECTIVE To investigate the role of the complement C3/C3aR signaling pathway in the prefrontal cortex and colon neuroglia cell interactions during meth-amphetamine(METH)addiction,to observe the effects of TLR4 inhibitors as well as complement C3 elimination on METH reward and relapse behavior,and to explore the neuroinflammatory mechanisms of complement C3 acti-vation in METH addiction.METHODS ①A 14 d and 28 d rat METH addiction model was established to observe the effects of TLR4 antagonist ibudilast 3 mg·kg-1 and 10 mg·kg-1 on self-administration,reward motivation,relapse,and natural reward behavior in METH-trained 14 d rats and the effects of 0.02 mg·kg-1 complement C3 antago-nist on self-administration behavior in METH-trained 28 d rats.② Differences in the expression of TLR4,NF-κB,GRP94,C3,cathepsin L,CD68,and GFAP in the pre-frontal cortex of each group were examined using West-ern blotting.③ In addition,the expression of ATF6 in the prefrontal cortex of each group and the effects on neuro-nal and microglia/macrophage INOS,CD206 GRP94,and complement C3/C3aR.RESULTS ① Endoplasmic reticulum stress occurred in neurons and microglia after METH exposure depending on GRP94 and unfolded pro-tein responses to the ATF6 pathway.In addition,it acti-vates the TLR4-NF-κB pathway.② Microglia with high complement C3/C3aR expression in the prefrontal cortex were recruited to synaptic pruning and phagocytic responses around neurons with high GRP94,comple-ment C3/C3aR expression and these effects were blocked by complement C3 antagonists.③ In the rec-tum,GRP94 functions as a molecular chaperone for com-plement C3 and cathepsin L.Crosstalk occurs between enteric neurons high in GRP94,complement C3,and macrophages high in C3aR,located in the submucosa,lamina propria,and muscular,respectively,and all of these effects are blocked by complement C3 antago-nists.④ Treatment with the TLR4 antagonist ibudilast inhibits self-administration,reward motivation,and cue-or METH-priming in METH-trained 14 d rats,but fails to affect natural reward behavior.Ibudilast treatment attenu-ates the TLR4-NF-κB inflammatory pathway and comple-ments C3/C3aR pathway in the prefrontal cortex.CON-CLUSION Activation of the complement C3/C3aR signal-ing pathway by TLR4-NF-κB inflammatory signaling in the prefrontal cortex mediates the METH addiction pro-cess,providing an experimental basis for the clinical treatment of METH addiction,and targeting TLR4/NF-κB inflammatory signaling and complement C3/C3aR may be a new way to intervene in METH addiction.

“Stasis generating deficiency” is considered to be an important pathogenesis of recurrence after catheter ablation of atrial fibrillation （AF）. Blood stasis is commonly seen after ablation together with various pathogens such as phlegm-fire， qi stagnation and retained fluid， and will lead to depletion of zang-fu （脏腑） organs and then the failure of the nourishment of the heart. Therefore， it is advised to emphasize on the importance of considering zang-fu organs depletion caused by blood stasis and various excess pathogens in dealing with the recurrence after catheter ablation. The method of dissolving stasis and supplementing deficiency simultaneously has been proposed before catheter ablation， and it is critical to calm heart and dissolve stasis， regulate and supplement internal deficiency so as to prevent the postoperative recurrence of AF. For recurrence of AF after ablation， attention should be paid to dissolving stasis and dispelling pathogens， regulating vessels and supplementing deficiency， as well as the excess pathogens such as stasis binding and phlegm fire， stasis binding and qi stagnation， stasis binding and retained fluid， and the depletion of zang-fu organs should be considered. Accordingly， the method of dissolving stasis and dispelling phlegm， subduing fire and unblocking vessels， regulating and supplementing heart and spleen； dissolving stasis and move stagnation， unblocking qi and blood， supplementing lung and boosting qi； dispelling stasis and dissolving rheum， warming yang and activating blood， consolidating the root and nourishing heart can be used respectively， so as to treat both the root and the branch simultaneously.
