Gingival recession or root exposure is associated with the loss of soft and hard tissue around the root. Gingival recession not only leads to aesthetic problem, but also affects tooth function, and even causes the loss of tooth. A case was diagnosed as gingival recession of upper incisor and periodontal-endodontic combined lesion. This report included the history of disease, clinical examination, X-ray film, treatment planning, root canal treatment and sequence of periodontal disease treatment (initial therapy, local drug therapy, bone graft and guided tissue regeneration combined with double laterally positioned flaps, subepithelial connective tissue graft and coronal positioned flap). The reasons of gingival recession, the methods of root coverage and the reconstruction of soft and hard tissue were also discussed on the basis of this case.

OBJECTIVE: To discuss the general regularity and the characteristics of the drug-induced edema caused by traditional Chinese medicine injections (TCMI) so as to provide basis for rational drugs use in the clinic. METHODS: 61 cases of drug-induced edema caused by TCMI publicly reported in domestic journal from 1994 to 2007 were analyzed statistically. RESULTS: The drug-induced edema caused by TCMI was not linked to sex and age. The symptom appeared in a short period and edema was induced in 44 cases within 30 min (72.1%). Laryngeal edema accounted for 54.1% and ocular angioedema 34.4%. 23 kinds of TCMI were involved, among which top 5 drugs in the list of incidence were Qingkailing injection, Shuanghuanglian injection, Yuxingcao injection, etc. CONCLUSION: Great importance should be attached to the monitoring of the clinical use of TCMI to promote the safety of TCMI.

Objective To investigate the sedation and analgesia clinical effects of dexmedetomidine and midazolam sufentanil in severe acute pancreatitis patients with mechanical ventilation.Methods Sixty four patients with mechanical ventilation in severe acute pancreatitis were randomly divided into dexmedetomidine and midazolam groups,and 32 cases in each group.All patients were routinely given sufentanil continuous intravenous analgesia.The patients in dexmedetomidine group received dexmedetomidine 1.0 μg/kg loading dose by intravenous injection and followed with 0.2 ～ 0.7 μg/(kg · h) continuous intravenous infusion.The patients in midazolam group received midazolam:0.05 mg/kg loading dose by intravenous injection and followed with 0.02 ～0.08 mg/(kg · h) continuous intravenous infusion.The sedation and analgesia effects and inflammation index changes in two groups were observed.Results The analgesia and sedation onset time,awake time and time of live in intensive care unit (ICU) in dexmedetomidine group were significantly superior to the midazolam group (P ＜ 0.05).Before weaning from mechanical ventilation the white blood cell count,C-reaction protein (CRP),heart rate,and respiratory frequency index in dexmedetomidine group were significantly better than those in midazolam group (P ＜ 0.05).The adverse event's incidence rate in dexmedetomidine group (9.38％) was ignificantly lower s than that in midazolam group (31.25％) (P ＜0.05).Conclusions The application of dexmedetomidine combined with sufentanil in severe acute pancreatitis patients with mechanical ventilation may play a good role of sedative and analgesic effects,and alleviating the inflammatory reaction of patients,as well as fewer adverse events.

Clinical nutrition, medical treatment and nursing constitute the three pillars in searching for the best curative effect. In view of the fact that the management and overall construction of the nutrition department seriously lags behind medical and nursing work, which impairs the quality and image of the hospital and hinders its overall development, the authors, basing themselves on the realities and having their eyes on the future, explore the overall construction of the nutrition department from the perspectives of disciplinary orientation identification, management system, personnel training, and hardware construction. They argue that the key to the construction of the nutrition department lies in identifying disciplinary orientations and implementing policy favor; carrying out the manning quotas and laying solid organizational foundations; strengthening personnel training and grasping key development opportunities; streamlining the management system and safeguarding a healthy development.

Objective To study the autonomic nervous regulation function,and to study relationship between heart rate variability and severity,organ dysfunction and prognosis in patients with systemic inflammatory response syndrome (SIRS).Methods All the patients were divided into two groups:SIRS and non-SIRS according to the criteria of SIRS. The SIRS group included 100 patients and the non-SIRS group 30 patients,and the control group included 30 heathy adults. SIRS group was further divided into two subgroups:survivor and succumbed.Heart rate variability(HRV)was analyzed with the two methods of time-domain and frequency-domain.Results The SIRS group had significantly higher APACHEll scores and MODS scores(P＜0.01)and lower HRV when compared with the non-SIRS group(P＜0.05).In the SIRS group,the succumbed groupallad statistically higher APACHEII and MODS scores and lower HRV than the survivor group( P＜0.01).There was a negative correlation between the prognosis of the patients and SDNN(r=-4.68,P＜0.01), SDNN＜55 ms was the most sensitive(76.2%),and specific(76.7%),with positive predictive value(90.4%)and negative predictive value(52.6%).Conlusion The SIRS patients had lower HRV,and there was a negative correlations with the severity of disease,organ dysfunction and prognosis.HRV(SDNN)were the useful index to evaluate the prognosis of critically ill patients.
