While the medicine pattern of biomedicine turn to biological-psychology-society, the medical trouble communication becomes more and more important in the medical service. Good medical trouble communication ability is the essential condition of doctor. As oral cavity clinicians, only by gasping the principle of communication can we appropriately utilize some skills of communication exchange,establish the good medical trouble relations with the patient and achieve the good treatment result finally.

BACKGROUND: Breast augmentation with polyacrylamide hydrogel injection has been used nearly for a decade in some Chinese medical therapy units. More patients need to be removing injections or a second augmentation due to complications. More attention should be paid for possibility of complications concomitant with breast malignant tumor. OBJECTIVE: Two cases of breast invasive duct carcinoma diagnosed after removing injection were analyzed retrospectively in order to increase the importance of detection rate of breast malignant tumor. METHODS: Two cases in all 41 assembled patients which were removed polyacrylamide hydrogel injections from 82 breasts were diagnosed with invasive carcinoma. The characteristics of medical history, physical diagnosis, image diagnosis and pathological examination were analyzed retrospectively. RESULTS AND CONCLUSION: The detection rate of breast malignant tumor should arise more attention in patients requiring removal of polyacrylamide hydrogel injection. The following aspects should be emphasized such as the comprehensive analysis for the results of physical diagnosis and image diagnosis, tumor-free operation with more samples from suspicious nodules and frozen pathological examination. The principles of cancer surgery should be followed in pathological diagnosed cases in case of iatrogenic metastasis and spread of breast malignant tumor.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.

Objective To explore the roles of serum TLR-4, TNF-αand IL-6 in neonates with preterm birth. Methods A total of 120 neonates from neonatology department in the Xingtai People's Hospital were selected and divided into full-term group (n=40), premature rupture of fetal membranes (n=40) and idiopathic preterm group (n=40) based on the gestational age. The peripheral venous blood was collected within 30 minutes when the infants were born, and the supernatant was reserved after centrifuged. The levels of serum TLR-4, TNF-αand IL-6 were detected by enzyme-linked immunosorbent assay. Results The levels of TLR-4, TNF-αand IL-6 in idiopathic preterm and premature rupture of fetal membranes were signiifcantly higher than that in full-term group and showed positive correlation. Conclusion Cytokines TLR-4, TNF-αand IL-6 maybe closely related to the preterm birth.

OBJECTIVETo investigate the anesthetic management features of laparoscopic adrenalectomy for pheochromocytoma.

METHODSTwelve patients scheduled for laparoscopic adrenalectomy for pheochromocytoma under general anesthesia were allocated into group 1, while another 12 patients who received transabdominal adrenalectomy for pheochromocytoma under general anesthesia were selected as group 2. The hemodynamic changes and the postoperative recovery profiles between the two groups were compared.

RESULTSHemodynamic fluctuation occurred during carbon dioxide insufflation and tumor manipulation in group 1. However, there were no differences between the two groups. Duration of post operative recovery and hospital stay as well as requirement of analgesics in group 1 were significantly lower than those in group 2 (P < 0.05).

CONCLUSIONHemodynamic fluctuation still exists during laparoscopic adrenalectomy for pheochromacytoma. However, patients undergoing such surgical procedure recover faster as compared with open surgery.

OBJECTIVETo study the inhibitory effect of paeoniflorin (PAE) on TNF-α-induced TNF receptor type I (TNFR1)-mediated signaling pathway in mouse renal arterial endothelial cells (AECs) and to explore its underlying molecular mechanisms.

METHODSMouse AECs were cultured in vitro and then they were treated by different concentrations PAE or TNF-α for various time periods. Expression levels of intercellular cell adhesion molecule-1 (ICAM-1) were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 6-h TNF-α 30 ng/mL), the low dose PAE group (cultured by 2-h PAE 0.8 μmo/L plus 6-h TNF-α 30 ng/mL), the middle dose PAE group (cultured by 2-h PAE 8 μmol/L plus 6-h TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 6-h TNF-α 30 ng/mL) with Western blot analysis. Nuclear translocation of transcription factor NF-κB (NE-κB) was detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 45-mm TNF-α 30 ng/mL), and the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 45-min TNF-α 30 ng/mL) by immunofluorescent staining. Expression levels of the phosphorylation of extracellular signal-regulated (protein) kinase (ph-ERK) and p38 (ph- p38) were detected in the normal group (cultured by serum-free culture media) and the high dose PAE group (2-h PAE 80 μmol/L culture) by Western blot. NF-κB inhibitor-α (IκBα) protein expressions were detected in the normal group (cultured by serum-free culture media), the TNF-α group (cultured by 2-h serum-free culture media plus 30-min TNF-α 30 ng/mL), the high dose PAE group (cultured by 2-h PAE 80 μmol/L plus 30-min TNF-α 30 ng/mL), the p38 inhibitor group (SB group, pretreatment with SB238025 25 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min), the ERK inhibitor group (PD group, treated by PD98059 50 μmol/L for 30 min, then treated by PAE 80 μmol/L for 2 h, and finally treated by TNF-α 30 ng/mL for 30 min) by Western blot.

RESULTSCompared with the normal group, ICAM-1 protein expression levels obviously increased (P < 0.01). Compared with the TNFα group, ICAM-1 protein expression levels were obviously inhibited in the high dose PAE group (P < 0.05). Protein expression levels of ph-p38 and ph-ERK were obviously higher in the hIgh dose PAE group (P < 0.05). Compared with the normal group, IκBα protein expression levels obviously decreased in the TNF-α group (P < 0.01). Compared with the TNFα group, TNF-α-induced IκBα degradation could be significantly inhibited in the high dose PAE group (P < 0.01); the inhibition of PAE on IκBα degradation could be significantly inhibited in the SB group (P < 0.05). NF-κB/p65 signal was mainly located in cytoplasm in the normal group. NF-κB/p65 was translocated from cytoplasm to nucleus after stimulated by 45 min TNF-α in the TNF-α group, while it could be significantly inhibited in the high dose PAE group.

CONCLUSIONSPAE inhibited TNF-α-induced expression of lCAM-1. Its action might be associated with inhibiting TNFR1/NF-κB signaling pathway. p38 participated and mediated these actions.

OBJECTIVETo observe the impact on lower limbs balance function in treatment of yin-yang meridians acupuncture with respiratory reinforcing and reducing manipulation involved in the patients of stroke by applying B-PHY balance function test training system so as to provide the objective evidence in treatment of stroke; with acupuncture.

METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the basic treatment was applied, without other relevant rehabilitation therapies associated. In the observation group, with the basic treatment as the control group's, the therapy of the yin-yang meridians acupuncutre with respiratory reinforcing and reducing manipulation was adopted. On the yin meridians, Zuwuli (LR 10), Xuehai (SP 10), Yinlingquan (SP 9), Sanyinjiao (SP 6) and the others were selected and stimulated with reducing manipulation achieved by the coordination of patient's respiration. On the yang meridians, Biguan (ST 31), Liangqiu (ST 34), Yanglingquan (GB 34) and the others were selected and stimulated with reinforcing manipulation achieved by the coordination of patient's respiration. The treatment was given once a day and for 28 days totally. Before treatment and in 28 days of treatment, B-PHY balance function test training system was used to determine the weight shift track parameters (track length, peripheral square, track length of per unit square, left-right offset and rectangle square), the weight shift track distance parameters [mean of X axle weight shift distance (Mean-X), mean of Y axle weight shift distance (Mean-Y), maximum of X axle weight shift distance (Max-X), maximum of Y axle weight shift distance (Max-Y), weight shift distance (LSKG), weight shift square (SSKG), square ratio of weight shift (LFS)], stability coefficient (SI) and weight distribution coefficient (WDI).

RESULTSAfter treatment, the differences in the weight shift track parameters, SI and WDI were significant as compared with those before treatment in the patients of the two groups (all P<0.01); while the differences in the weight shift distance parameters in the observation group were improved obviously after treatment as compared with those before treatment (all P<0.01), the differences of Mean-X, Max-Y and LFS in the control group were improved after treatment as compared with those before treatment (all P<0.01). Except SSKG, the improvements after treatment in the rest indices in the observation group were better than those in the control group (all P<0.05).

CONCLUSIONThe yin-yang meridians acupuncture with respiratry reinforcing and re- ducing manipulation effectively improves the lower limbs balance function in the patients of stroke.

OBJECTIVETo investigate influential factors for the tendency to medicate and medication compliance in children with attention deficit hyperactivity disorder (ADHD).

METHODSA total of 188 children aged from 5 to 16 years, who were initially diagnosed with ADHD according to DSM-IV criteria, were included in the study. They underwent symptom assessment and cognitive function test. The compliance of methylphenidate treatment was evaluated.

RESULTSPatients with better emotional state, and fewer oppositional and hyperactive behaviors and those who had a family history of psychiatric diseases and who obtained lower scores in the number cancellation test (NCT), were more prone to medication and/or exhibited better medication compliance. Logistic regression analysis showed that fewer oppositional and hyperactive behaviors and lower NCT scores were the predictive factors for a higher tendency to medicate, and a better emotional state was the predictive factor for better medication compliance. Patients of predominantly inattentive type were more prone to medication and showed better medication compliance, as compared with those of combined type. Gender, age and symptom severity were not associated with the tendency to medicate and/or medication compliance.

CONCLUSIONSThere is a need to enhance medication compliance in children with ADHD who have hyperactive, impulsive and oppositional behaviors, and to improve their long-term social functions.

OBJECTIVETo retrospectively study medium-term follow-up outcomes of total hip arthroplasty (THA) for patients with ankylosing spondylitis (AS).

METHODSFrom January 2000 to December 2008, 67 patients (88 hip joints) with AS were treated with all ceramic interface THA. And 55 patients (74 hips) were finally followed up. Among them, there were 30 males and 25 females, with an average age of 32.6 (ranged 19 to 58) years old. Sixty-one hips were treated with biological prosthesis and 13 hips were treated with hybrid prosthesis. Fifty-five patients were followed up at least 5 years, with an average of (75.2 +/- 8.6) months. Clinical symptoms and radiography information were evaluated after follow-up.

RESULTSHarris hip score were significantly improved from 30.8 +/- 7.0 preoperatively to 85.2 +/- 5.5 at the last follow-up (P<0.01). The hip movement range increased from (21.2 +/- 8.5) degrees preoperatively to (142.0 +/- 10.2) degrees postoperatively (P<0.01). The 5-year survival of prosthesis was 95.9%. One patient were renovated because of internal wall broken caused by injury, 1 was renovated for infection, 1 was renovated for fracture arround femoral stem prostheses, and 1 was treated with conservative treatment by dislocation. Three cases with abnormal sound were cured with non-operation. 7 cases with heterotopic ossification were not treated, 2 cases with thigh pain received conservative treatment. Bone dissolve around prosthesis, loose and sink of femur and acetabulum prosthesis were occurred in other cases.

CONCLUSIONTHA for the treatment of AS is a reliable method, which has a satisfied medium-term follow-up outcomes.

OBJECTIVETo screen the differently expressed proteins related to regulating the depolymerization of microtubules in the spinal cord of hens exposed to tri-o-cresyl phosphate (TOCP) and to provide target protein evidence for exploring the mechanisms of the delayed neurotoxicology (OPIDN) induced by organophosphorus compounds (OPs).

METHODSForty two Roman hens were randomly divided into three groups, i.e. TOCP group treated with 1000 mg/kg TOCP; intervention group treated with 40 mg/kg phenylmethanesulfonyl fluoride (PMSF) before 1000 mg/kg TOCP treatment and control group treated with tap water. Four hens in each group were sacrificed on the 5th and 20th days after exposure, respectively. Spinal cords were separated and homogenates at low temperature, and the total proteins were extracted. The OPIDN symptoms observed and recorded in the remaining 6 hens in each group. The differently expressed proteins related to regulating the depolymerization of microtubules were screen by two-dimensional electrophoresis and mass spectroscopy (MS).

RESULTSThe OPIDN symptoms appeared on the 5th day after exposure in TOCP group, which were gradually serious with time. The results by two-dimensional electrophoresis and MS showed that the Stathmin expression was downregulated 3.4 times and 2.8 times in TOCP group, respectively, as compared with the control and PMSF intervention groups. However, there was no significant difference of the Stathmin expression between control group and PMSF intervention group.

CONCLUSIONThe Stathmin expression in the spinal cord tissues of hens exposed to TOCP significantly downregulated. Moreover, the downregulated Stathmin expression may be related to excess polymerization of microtubules and the mechanism of OPIDN.
