Psychotherapy is a sort of arts based on science following the general principles of social science and natural science.Meanwhile,the content of psychotherapy,the process of the practice,and the relationship be-tween the help-seekers and the helpers reflect substantial humanistic connotation and are bound up with cultural and subcultural transmission and reality context.This paper is a commentary on the article written by an Indonesian fel-low T.Citraningtyas discussing the mother's role in the matriarchal society and its modern meanings.We discussed that the phenomenon of being cultural extinctionalso presents in China.Although the main stream in Chinese cul-ture is still patriarchic familism,the remainder of matriarchal society still exists in the basic emotional models of parent-child relationship.The deprivation and frustration related with filial piety and kinship may cause the conse-quence of cultural extinctionin the individual level.Referring the theory of Wen-Shing Tseng on the mechanisms of the cultural influence on psychopathology,from the perspective of understanding psychology,we emphasized the importance of cultural empathy and recommended the systemic clinical thinking way of empathic considering and contextualizing.Last but not least,we discussed the second case of the overseas migrant workers and their left-at-home childrenin this article within Chinese context.Moreover,besides the 61 million left-at-home children in rural areas,there are a large amount of substitute-raised children by their grandparents who might be also in the risk of being impaired physically and psychologically.This problematic phenomenon may relate to the living stress and the cultural encouragement as well.By providing a critique discussion with the related theories of correlation of the in-secure attachment with psychological disorders in childhood and adulthood,this commentary encouraged humble learning from our Indonesian fellows and appealed for greater appreciation of separate mothers and their children a-mong Chinese clinicians.

Objective To investigate the correlation of HIF-1α and hypoxia in keloids fibroblasts, and to investigate the mechanism that hypoxia promotes abnormal scarring by HIF-1α pathway. Methods Keloid fibroblasts cultured in vitro were placed in an incubator with different O2 concentrations. After 24 h, the keloid fibroblasts were collected for further study. Western blotting was performed to detect the expression of HIF-1α in the keloid fibroblasts. Results Relative amounts of HIF-1α in keloid fibroblasts cultured under O2 concentrations at 20 %, 10 %, 5 % and 1 % were 0. 007 ±0. 006, 0. 133 ±0. 006, 0. 537±0. 015 and 0. 903±0. 021, respectively. It indicated that hypoxia could increase the expression of HIF-lα in keloid fibroblasts. Conclusions Hypoxia can induce the expression of HIF-1α in fibroblasts of keloids. Moreover, there still is a positive relation between hypoxia and the expression of HIF-1α. Therefore, a close relationship exists between abnormal scarring and HIF-1α pathway by hypoxia.

Objective:To optimize the formula of 5-aminosalicylic acid enema in situ gel. Methods:5-Aminosalicylic acid ene-mas in situ gel was prepared using a cold dissolution method with carbomer as the gel matrix and xanthan gum as the thickener. A 32 full factorial design was used to investigate the effects of the concentrations of carbomer and xanthan gum on the viscosity before and af-ter the gelling, duration of inversion tube and sedimentation rate. Response surface methodology was used to optimize the formula. Re-sults:The quantitative relationships between the two factors and the four evaluation indices were obtained. The optimum formula was as follows:the concentration of carbopol and xanthan gum in the enema was 0. 7% and 0. 15%, respectively. The viscosity before and af-ter the gelling was 500-1 000 mPa·s and 2 200-2 700 mPa·s, respectively. The duration of inversion tube test was 40-80 min and the sedimentation rate was more than 98. 5%. Conclusion:The multi-objective simultaneous optimization of the formula of 5-aminosal-icylic acid enema in situ gel is accomplished by factorial design and response surface methodology.

Objective To summarize and evaluate the incidence,etiology,diagnostic and therapeutic method of hepatic dysfunction after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods 83 blood disease patients who undergoing allo-HSCT from 2006 to 2010 in the affiliated cancer hospital of Zhengzhou university.Among those who suffered from Ⅱ-Ⅳ grade hepatic dysfunction,the incidence,the ratio of different causes,clinical feature and diagnostic method were evaluated.The difference of causes of hepatic dysfunction in different period,the therapeutic method and curative effect were also analysed.Results Among 83 patients undergoing allo-HSCT,45 patients suffered from Ⅱ-Ⅳ grade hepatic dysfunction,the ratio was 54.2 ％.For etiology,7 were preconditioning,9 were cyclosporine (CsA),2 were hepatic venoocclusive disease (HVOD),24 were hepatic graft versus host disease (GVHD),2 was hepatic B virus (HBV)reactivation,1 was mutiple organ failure.20 cases (44.4 ％) occurred in one month after allo-HSCT with the main etiology of drug hepatotoxicity.13 cases (28.9 ％) occurred from one month to 100 days after allo-HSCT,while 12 cases (26.7 ％) occurred from 101 days to one year with the main etiology of both hepatic GVHD.27 cases were cured and 10 were improved after treatment.2 cases were not cured and 6 cases died from relapse of the primary disease,or else from the complication of allo-HSCT.Conclusion Hepatic dysfunction is an common complication after allo-HSCT,drug hepatotoxicity and hepatic GVHD are the major causes.The relativity between hepatic dysfunction and period after allo-HSCT is a important reference for diagnosis.It will produce desired result to choose proper therapeutic method based on etiology.

Objective To discuss the technical skill of super-selective catheterization for “one-way valve occlusion” of the common hepatic artery during transcatheter arterial chemoembolization (TACE). Methods A total of 128 patients with “one-way valve occlusion”of the common hepatic artery were enrolled in this study, who were admitted to authors’ department to receive TACE during the period from 2000 to 2011. The lesions included hepatocellular carcinoma (n = 110), cholangiocellular carcinoma (n = 3) and hepatic metastasis (n=15). “One-way valve occlusion”of the common hepatic artery occurred in 90 patients (70.3%, 90/128) after 2-5 times of TACE had been carried out, and in the other 38 patients (29.7%, 39/128) the “one- way valve occlusion” of the common hepatic artery was recognized at the initial TACE procedure. Super-selective hepatic catheterization was performed via the superior mesenteric artery (SMA) approach or celiac artery (CA) approach using coaxial micro-catheter catheterization technique. The success rate and fluoroscopy time of super-selective catheterization were recorded, and the results were compared between the two approaches. Results A total of 337 times of hepatic super-selection catheterization were performed in 128 patients, with a mean of 2.6 times for each case. The success rate was 100%. Of the 337 procedures, the catheterization was via CA approach in 148 (43.9%, 148/337) and via SMA approach in 189 (56.1%, 189/337). The mean fluoroscopy time in CA approach group was 3.2 minutes(ranged 1-6 minutes), and in SMA group was 15.3 minutes(ranged 5-40 minutes). The difference between the two groups was statistically significant (P < 0.05). Conclusion Super- selective hepatic catheterization for “one-way valve occlusion” of the common hepatic artery can be achieved through SMA approach or CA approach by using coaxial micro-catheter catheterization. Compared with SMA approach, the technique of hepatic catheterization through CA approach is much simpler and the fluoroscopy time is significantly shorter.

Objective To evaluate the influence of thermal damage on the cell proliferation,invasive metastasis and epithelial-mesenchymal transition of hepatocellular carcinoma (HCC) through experiments in vitro,and to explore the relationship between thermal ablation and the recurrence,metastasis of HCC.Methods The McA-RH7777 HCC cell thermal damage model was established by using external heating method.The effect of thermal damage on the proliferation of HCC cells was detected by Kit-8 assay (CCK-8),and the cell cycle changes were studied by flow cytometry.The effect of thermal damage on the invasion potential of HCC cells was assessed by using Transwell assay.Fluorescence quantitative polymerase chain reaction (RT-PCR) and Western blot were used to evaluate the influence of thermal damage on HCC cell invasion potential,and on the mRNA and protein expression levels of EMT-related molecular markers,including VEGF,MMP-9,Nm23,E-cadherinand vimentin.Results Heating treatment of McA-RH7777HCC cells was performed by putting the cells in 43.5℃ water basin for 30 min.Two to five days after heating treatment the cell proliferative ability was significantly higher than that of control group (P＜0.05).At 48-72hours after heating treatment the proportion of HCC cells in G1 phase was obviously reduced and the proportion of HCC cells in S+G2 phase was significantly increased,the differences were statistically significant (P＜0.05).Compared with the control group,the difference in HCC cell invasion potential determined at 24 h after heating treatment was not significant,while the HCC cell invasion potential determined at 72 h after heating treatment was strikingly increased (22.3±2.46 vs.14.2±l.82,P＜0.001).Real-time PCR and Western blotting results indicated that at 72 h after heating treatment the expression levels of VEGF,MMP-9 and vimentin were significantly increased,while the expression level of E-cadherin was remarkably decreased,the differences were statistically significant (P＜0.05).Conclusion Thermal damage with sub-lethal heating dose can induce McA-RH7777 HCC cell to develop epithelial-mesenchymal transition and to enhance its proliferation and invasive metastasis potential,and HCC cells show higher malignant potential.
