Acupoint,as the special body surface part where the qi of zang-fu and meridians infuses, arouses the effect of acupuncture and moxibustion. Through the exploration for the origin and the evolution of acupoint, and the integration of the related data about acupuncture-moxibustion theory and modern research, it is believed that acupoint is not fixed and it may be in a state of dynamic change. Also, it is bound up with body function. Acupoint is relatively static and the location is immobile while the body is in normal physiological status. When the body is under pathological condition,however, it is activated and the position is correspondingly changed.

Fine-needle aspiration biopsy is the mainstay of preoperative diagnosis of thyroid cancer which is the most common type of endocrine malignancy.However,some aspirates yield indeterminate cytology and there is no clear recommendation for the management on these situations.The use of emerging molecular markers such as BRAF、RET、PAX8/PPARγ will likely improve the diagnosis of malignancy in thyroid nodules and facilitate more individualized therapeutic options and postoperative management.Some markers have been extensively characterized and introduced into clinical practice.

Brain injury is the leading cause of death after cardiopulmonary resuscitation.Clinical care for brain injury remains necessary.Therapeutic hypothermia has been shown to be effective in improving neurological outcome of children with cardiac arrest.We routinely induced hypothermia in children with coma after cardiac arrest,targeting 32 ～ 34 ℃,using cooling blankets and intravenous ice cap as primary methods for induction,for 24 ～ 72 h or much more duration,and vigilant re-warming.The objective of this article was to share our hypothermia protocol for cooling children with acute brain injury after cardiac arrest.

Objective To explore the glucose and liplid metabolism changes of pregnant rats and the birth weight of their offsprings due to pregnancy malnutrition,including overnutrition and undernutrition.Methods Thirty pregnant Wistar rats were randomly divided into three groups on the day of conception,the high-fat-diet group,normal control group and 50％ food-restricted diet group.Increase of body weight and serum level of triglycerides,high-density lipoprotein,low-density lipoprotein,oral glucose tolerance test (OGTT) and insulin release test(IRT) levels during pregnancy were measured.The birth weight of offsprings was recorded within 12 h after birth.One-way ANOVA,LSD or Dunnett T3,and Chi-square test were applied for statistical analysis.Results The body weight at late pregnancy and the level of triglycerides and low-density lipoprotein were significantly increased in the high-fat-diet rats compared to normal control ones [(1.68±0.13) mmol/L vs (0.78±0.08) mmol/L,(0.57±0.04) mmol/L vs (0.35±0.07) mmol/L; both P＜0.01].While the level of high-density lipoprotein of high-fat-diet rats was lower than that of the normal control rats [(0.56±0.06) mmol/L vs (1.09±0.08) mmol/L,P＜0.05].The level of triglycerides,low density lipoprotein and high density lipoprotein in 50％ food restricted group [(0.47±0.06) mmol/L,(0.21±0.06) mmol/L and (0.42±0.05) mmol/L] were lower than the control group (all P＜0.05).Impaired glucose tolerance,abnormal OGTT and IRT results were found in both high-fat-diet and 50％ foodrestricted diet rats.The fasting plasma glucose level in high-fat-diet group was significantly increased in late pregnancy compared to the control [(6.63±0.53) mmol/L vs (4.90±0.26) mmol/L,P＜0.05],while there was no significant difference between rats in 50％ food-restricted diet [(4.18±0.26) mmol/L]and control group (P＞0.05).There was no statistical difference in fasting serum insulin level among the three groups.The average birth weight was significantly increased in high-fat-diet rats than in the control group [(6.14±0.31) g vs (5.73±0.26) g,P＜0.05],and the incidence of macrosomic newborn rats in the high-fat-diet group was also higher than that of the control group [19.2 ％ (19/99)vs 7.84％(8/102),P＜0.05].The birth weight of offspring in 50％ food-restricted diet group was decreased with their average birth weight of (4.54±0.23) g,which was lower than that of the control group (P＜0.05).The incidence of macrosomic [13.40％ (11/76)] and low birth weight newborn rats [15.90％ (13/76) vs 3.92％(4/102)] in food-restricted diet group were both higher than in the control group (P＜0.05); and smaller number of offsprings was obtained than the control group (76 vs 102,P＜0.05),the number of offsprings in high-fat-diet group was 99,which was less than the control group without statistical difference (P＞0.05).Conclusions Pregnancy malnutrition,including overnutrition and undernutrition,may affect the lipid metabolism and glucose tolerance of pregnant rats,leading to insulin resistance,and may also contribute to the abnormal birth weight of the offspring,including macrosomia and low birth weight.

BACKGROUND:Silver ion dressing can reduce tissue necrosis, accelerate the epithelial formation, relieve the patient’s pain during the treatment, and strengthen various growth factors for wound repair, which is based on the theory of wet healing theory. It has obvious advantages for chronic wound healing, such as anti-infection and promoting wound granulation and epithelial hyperplasia.
OBJECTIVE:To observe the efficacy of silver ion dressing used in healing of chronic wound.
METHODS:A total of 40 patients who had chronic wounds were selected from Tangshan Branch Hospital of Nanjing General Hospital of Nanjing Military Command. Al cases were divided into two groups. The treatment group was treated with silver ion dressing, and the control group was treated with routine dressing. Secretions extracted from wound were used for bacterial culture prior to and 7, 14, and 21 days after treatment. Healing condition and velocity were observed and wound pain was assessed using visual analog scale.
RESULTS AND CONCLUSION: The detection rate of wound bacteria in the treatment group was significantly lower than that of the control group (P<0.05). And the time of healing was shorter in the treatment group than the control group (P<0.05). Wound pain during dressing change was relieved (P<0.05). Medical costs showed no difference between the two groups (P>0.05). No adverse reaction occurred in the two groups. These findings indicate that silver ion dressing used in chronic wound healing can prevent infection and promote wound granulation or epithelial hyperplasia. It can effectively promote wound healing and has no bad reaction.

Objective To analyze the surgical management and prognosis of hilar cholangiocarcinoma(HCC).MethodClinical data of 72 patients with HCC were retrospectively analyzed.Results There was a significant difference in the 3- and 5- year survival rates and median survivals among the groups treated with different surgical methods(x2 =28.1,P＜ 0.01 ).Univariate analyses conducted for the 16 factors which might affect prognosis showed the surgical method,lymphatic metastasis,positive margin,as well as the type of pathology and staging were of statistically significant prognostic value (P＜0.05).On a multivariate analysis using the Cox proportional hazards model,surgical management,lymphatic metastasis and the type of pathology and staging were independent prognostic factors (regression coefficient 1.4157,1.1072,1.6435).ConclusionRadical excision is an important prognostic factor for HCCa and extended resection improved the long-term survival rates of radical surgery.

Objective To explore the effects of patient mutual help-oriented nursing model on social support and hope level in lung cancer patients.Methods Totally 72 lung cancer patients were recruited into the study and divided into the experimental group and the control group with 36 patients in each group.The control group was given routine care,while the experimental group received additional patient mutual help-oriented nursing interventions:physically and psychologically well recovered patients were asked to give emotional communication and interaction to patients newly diagnosed with lung cancer,The Social Support Scale and Herth Hope Index were used for evaluation after the intervention.Results The patients' social support and hope level of the intervention group were significantly better than those of the control group after intervention.Conclusions Patient mutual help-oriented nursing model can improve social support and hope level of lung cancer.
