The determination of tumor markers is of great value for esophageal squamous cell carcinoma. This article reviews the application status of routine tumor markers and the progression on the role of tumor markers in early diagnosis, predicting chemotherapy or radiotherapy response, monitoring disease recurrence and evaluation of prognosis in esophageal squamous cell carcinoma.

Objective:To assess mechanical hyperalgesia of the bilateral masseter muscles following the induction of experimental unilateral malocclusion in rats. Methods:① An elastic rubber(3M Unitek,1/8#) was inserted between the first and sencond upper molars on the left side of 4 Sprague- Dawley rats to induce malocclusion.② The left maxillary first molar of 4 rats were filled with metal arsenic for 7 days to inactivate tooth pulp, and then a dentin pin(d 0.75 mm, long 1.5-2.0 mm,0.5-1.0 mm above the occlusion surface)was bonded in the pulp chamber to induce acute traumatic occlusion, and 4 control animals were treated as the same procedure but not raised occlusion surface.③ According to Ren's method, von Frey filaments were used to assess the muscle mechanical threshold.Head withdrawal, leg raising and crying were observed as painful actions. Results:① In gradually induced malocclusion group,hyperalgesia was induced in bilateral masseter muscles from 3 to 9 d, and the peak time was the 7th day. ②In the acute traumatic occlusion group, the ipsilateral masseter muscle was demonstrated hyperalgesia for 5-7 days, and the peak time was the 2nd day. Conclusions:Traumatic occlusion may lead to masseter muscles hyperalgesia, and there existe some differences for pain behavior between the acute and the chronic occlusion trauma.

Objective To compare the effect of crystalloid and crystalloid plus albumin in the treatment of pediatric septic shock.Methods Data of 63 pediatric patients with septic shock admitted to Department of Critical Care Medicine of Hebei Provincial Children's Hospital were collected and retrospectively analyzed.The patients were divided into two groups according to whether they received albumin for volume resuscitation within 1 day after admission or not.The patients in observation group (crystalloid + albumin group,n =33) received normal saline (20 mL/kg) followed by 1 g/kg albumin 30 minutes after admission,and those in control group (crystalloid group,n =30) received only normal saline (20 mL/kg) 30 minutes after admission,and normal saline resuscitation was continued according to the effect of fluid therapy.Anti-infection and vasoactive drugs strategies were the same in both groups.The first-hour infusion volume,time showing stable hemodynamics,the incidence of pulmonary edema,and blood lactate levels at 0,6,12 hours after achieving the goals were compared,and blood lactate clearance rates were calculated.Results The first-hour infusion volume time in the observation group was lower than that in control group (mL:41.56 ± 10.50 vs.57.24 ± 7.54,t=4.596,P=0.000),and time showing stable hemodynamics was shorter than that in control group but without statistically significant difference (minutes:219.87 ±70.23 vs.287.10 ± 67.00,t=2.047,P=0.360).The incidence of pulmonary edema in observation group was slightly lower than that in control group [6.1％ (2/33) vs.10.0％ (3/30),x2±2.272,P=0.259].The lactic acid levels were decreased gradually along with rehabilitation time,while lactate clearance rate was increased in both groups.At 0 hour and 6 hours after resuscitation,the lactate level (mmol/L) in the observation group was significantly lower than that in control group [0 hour:3.65 ± 2.84 vs.5.72 ± 2.11,t＝ 1.940,P=0.046; 6 hours:2.12 ± 1.21 vs.4.09 ± 1.45,t=2.892,P=0.005],while the lactate clearance rate was significantly increased compared with control group [0 hour:(0.38 ± 0.15)％ vs.(0.18 ± 0.09)％,t=1.447,P=0.018; 6 hours:(0.62 ± 0.14)％ vs.(0.51 ± 0.11)％,t=1.920,P=0.047].However,at 12 hours after resuscitation,there were no statistically significant differences in the lactic acid level (mmol/L:1.46 ± 0.39 vs.1.54 ± 1.90,t=0.450,P=0.072) and the lactate clearance rate [(0.78 ± 0.19) ％ vs.(0.77 ± 0.18) ％,t =0.091,P=0.928] between observation group and control group.Conclusion Albumin resuscitation in children with septic shock can stabilize hemodynamics earlier,reduce the incidence of pulmonary edema,and improve the successful rescue rate of refractory septic shock.

Objective To assess the predictive and prognostic role of the alteration of serum carcinoembryonic antigen (CEA),squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragment (CYFRA21-1) during chemotherapy in patients with advanced esophageal squamous cell carcinoma (ESCC).Methods The serum levels of CEA,CYFRA21-1 and SCC-Ag were measured in 50 patients with advanced ESCC at baseline and after first line chemotherapy.The data was correlated with objective efficacy and overall survival.To evaluate the role of tumor marker change in predicting response to therapy,receiver operating characteristic (ROC) curves were constructed.Results CEA,SCC-Ag and CYFRA21-1 increased higher than the cutoffs in 22.0 %,34.0 %,and 44.0 % of tested patients,respectively.Statistically significant correlations were observed between CYFRA21-1 and SCC responses and objective efficacy evaluated by RECIST criteria (Z =3.181,2.389; P = 0.001,0.017).Based on the ROG curve analysis,a post treatment 32 % and 38 % increase in serum concentration was used as cut-off level for defining CYFRA21-1 and SCC-Ag change,respectively.When the cut-off levels were used to predict chemotherapy efficacy,the accuracy for CYFRA21-1 and SCC-Ag were 76 % and 70 %.In the univariate survival analysis,a statistically significant prognostic impact on survival from the change of CYFRA21-1 and SCC-Ag was observed.Conclusion CYFRA21-1 and SCC-Ag are useful for diagnosis,predicting chemotherapy objective efficacy and prognosis in advanced ESCC.

Objective To explore the effect of using pedicle skin flaps for treatment of skin and soft tissue defects.Methods From January 2004 to September 2010,87 patients with skin and soft tissue injury which had been treated by using pedicle skin flaps without vessel anastomosis were retrospectively analyzed,including 61 males and 26 females with an average age of 40 years (range,14-61).The pedicle skin flaps selected were known vessel skin flaps or unknown vessel random skin flaps.The reconstruction treatment increased multiple selections of skin flaps for patients.Skin and soft tissue defects were located at the hand in 21 cases,at the lower extremities in 66.The kinds of skin flaps included adjacent transposition flaps in 50 cases,distal skin flaps in 37.The areas of the skin flaps were 2.0 cm×1.5 cm-18 cm×12 cm.Donor sites were as follows:lower leg in 61 cases,abdomen in 18,and hand in 8.Results Three patients appeared skin flaps hematoma after operation,which were removed immediately with no effect on flaps survival.Pedicle skin flap was compressed due to unstable fixation in 1 case,which made distal flap tissue necrosis approximately 2 cm in width.After dressing change for 6 weeks,the flaps got survival.Thirty seven patients underwent the second stage operation for breaking the perdicle 3 weeks after the first operation.All 87 patients were obtained follow-up for an average of 13 months (range,3-60).The total of 90.80％ patients treated with pedicle skin flaps were satisfied with the results.Conclusion Pedicle skin flap surgery can be performed more easily with less limitations of surgical designs.The survival rate of the flap is high,and the treatment of pedicle skin flaps could be well applied for soft tissue defects.

Objective To evaluate the effect of raltitrexed plus oxaliplatin combined with concurrent radiotherapy on life quality of advanced esophageal carcinoma.Methods Oesophageal cancer specific health related quality of life questionnaire(QLQ-OES18) was used to evaluate the life quality of 54 patients with esophageal carcinoma respectively at 1 day pre-treatment(baseline level),1 day post-treatment and 1month post-treatment.Total 54 patients were treated with raltitrexed plus oxaliplatin combined with con-current radiotherapy.Comparing the differences of quality of life scores at different time points,and analyzing the correlation of the differences between the 1month post-treatment and baseline score and short term effect.Results The scores of difficulty swallo-wing,eating difficulties,saliva decreased significantly at 1 day post-treatment than that of pre-treatment(P<0.05),the scores of eating pain increased significantly at 1 day post-treatment than that of pre-treatment(P<0.05)and there was no significantly differ-ences in other items(P>0.05).The scores of 1 day post-treatment were significantly reduced compared to baseline levels except re-flux and speech(P<0.05).It was positive correlation between the difference of 1 month post-treatment and baseline score and short term effect,and the correlation coefficients was 0.85,0.55,0.73,0.32(P<0.05),respectively.Conclusion There is a transient im-pact of raltitrexed plus oxaliplatin combined with concurrent radiotherapy on quality of life for advanced esophageal carcinoma after treatment,but most of the life quality of the patients could be improved after 1 month obviously.

Objective To evaluate the effects of electroacupuncture (EA) at the Baihui (DU 20) and Dazhui (Bill) points on brain derived neurotrophic factor (BDNF) around the area of cerebral infarction and evaluate the relation between learning and memory ability and BDNF. Methods Forty-eight male adult Wistar rats were divided randomly and equally into EA and control groups. The EA group was sub-divided into 1 week, 2 weeks and 3weeks sub-groups. EA was started 24 h after establishing a model of ischemic brain injury and continued for one, two or three weeks. The control group was reared conventionally and was not given any treatment. Morris' water maze test was used to evaluate the rats' learning and memory ability. The expression of BDNF in the CA3 region of the hippo campus was detected using immunohistochemical techniques. Results Learning and memory in the EA groups were better than in the control group, and spatial probe ability was also significantly better. Positive expression of BDNF was detected in the hippocampal CA3 region of the EA group rats, and it was significantly greater than that in the control group. Conclusion Learning and memory after cerebral infarction can be affected by EA at the Baihui and Dazhui points. The effect might be related with increased BDNF expression in the hippocampal CA3 region.

Objective To investigate the expressions of advanced glycation end products (AGEs) and their receptors in keloid. Methods Serum and skin tissue specimens were collected from 20 patients with keloid, 20 patients with hyperplastic scar and 20 normal human controls. Fluorospectrophotometer was used to measure the serum level of AGEs, and immunohistochemistry and Western blotting to detect the expressions of AGEs and AGER in skin tissue specimens. Results The serum level of AGEs was (0.713 ± 0.098) AU/ml and (0.699 ± 0.077) AU/ml respectively in patients with keloid and those with hypertrophic scar, significantly higher than that in normal controls (0.179 ± 0.056 AU/ml, F = 283.82, P < 0.01 ). A positive expression of AGEs and AGER was observed in tissue specimens of keloid and hyperplastic scar, but not in the control specimens. As Western blotting showed, the expressions of AGEs and AGER were higher in tissue specimens of keloid and hyperplastic scar than in the control specimens (F = 18.04, 42.80, both P < 0.05), while no significant difference between keloid and hyperplastic scar tissue specimens was observed (P> 0.05). Conclusion There is a high expression of AGEs and AGER in keloid, which may contribute to the development of keloid.
