Lysosomal associated protein transmembrane 4 B (LAPTM4B) is a recently discovered gene with the characteristics of oncogenes. This article presents a preliminary review of the structure, biological function and genetic polymorphisms of LAPTM4B and its role in cancer prognosis.

Objective To evaluate the clinical value of serum procalcitonin (PCT) in the diagnosis and differentiation of bacterial infections in the critically ill patients. Methods A total of 53 critical patients were divided into bacterial infection group and non-bacterial infection group. Serum PCT was measured by immunoluminometric assay. Results PCT of bacterial infection group was significantly higher than that in non-bacterial infection group (?~2=0.05, P

Objective To investigate the role of extracellular signal-regulated kinase1/2 (ERK1/2) in the central amygdala on fentanyl-induced hyperalgesia in rats.Methods Thirty-two male SpragueDawley rats, weighing 60-100 g, were randomly divided into 4 groups (n =8 each) using a random number table: control group (group C), fentanyl-induced hyperalgesia group (group H), U0124 group (group U1) , and U0126 group (group U2).A catheter was implanted in the central amygdale.In group C, normal saline was injected subcutaneously, and 6.5 h later dimethyl sulfoxide (DMSO) was injected via the catheter.In group H, fentanyl was injected subcutaneously to induce hyperalgesia, and 6.5 h later DMSO was injected via the catheter.In group U1, hyperalgesia was induced, and 6.5 h later ERK1 inhibitor U0124 1.5 nmol was injected via the catheter.In group U2, hyperalgesia was induced, and 6.5 h later ERK1/2 inhibitor U0126 1.5 nmol was injected via the catheter.Mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal threshold (TWT) were measured before fentanyl injection, at 6.5 h after injection, and at 30 min after DMSO or U0124/U0126 administration via the catheter (T0-2).After the last measurement of pain threshold, the rats were sacrificed, and the amygdala tissues were sampled for detection of the expression of phosphorylated ERK1/2 (p-ERK1/2) by Western blot in groups C and H.Results Compared with group C, the MWT and TWT were significantly decreased at T1,2in H and U1 groups, and at T1in group U2 (P＜0.05) , the expression of p-ERK2 was up-regulated (P＜0.05) , and no significant change was found in the expression of p-ERK1 in group H (P＞0.05).Compared with group H,the MWT and TWT were significantly increased at T2 in group U2 (P＜0.05) , and no significant change was found in MWT, TWT in group U1 (P＞0.05).Conclusion ERK2 activation in the central amygdala is involved in the development of fentanyl-induced hyperalgesia in rats.

A new chromene (1) and six known compounds identified as 6-hydroxymellein (2), 6-hydroxy-5-methylmellein (3) nectriapyrone (4), chermesinone A(5), chermesinone B(6), and pomopxanthone A(7), were isolated in our investigation of the cytotoxic constituents from the fermented rice substrate of endophytic fungus Phomopsis sp. HCCB03519. The structures of these com pounds were elucidated through spectroscopic data analysis. All compounds exhibited inhibitory activities against cancer cell lines. Compound 7 showed stronger inhibition against cancer cells than the positive control 5-Fu.

Objective: To observe the efficacy of skin regenerative medical technique in treating proliferative scars. Method: Select 32 patients (age16-52) with proliferative scars after burns or wound for 1-11 years,which include 25(male) and 7(female). 2 scar similar spots are chosen in each patient for self-comparison.After the experimental group uses the scar detachment, scar Pi Huizhi applies the beautiful valuable moist burn medicinal plaster gauze cover the cooperation of Chinese and Western medicine home position skin regenerative method treatment; After the control group uses the scar detachment, scar Pi Huizhi applies the petroleum jelly cover the traditional method treatment.The observation comparison curative effect, applies the Vancouver scar appraisal meter appraisal scar proliferation situation. Results: Two groups return to the scar skin which plants to survive.The experimental group regenerates the skin to be good, the cicatrization speed and the quality surpass the control group (P

Objective To study the method of treatment of esophageal stricture and ulcer in children caused by corrosive injury using esophageal stent.Methods The stent made of stainlees steel Z type covered with thin membrane or Ni-Ti shape memory wire mesh-like stent was used and placed through mouth by the transport of tracheal stent in 12 cases.Results Symptoms of the dysphagia in all 12 cases treated with 18 sets of Z stents were alleviated remarkably.Following up study from 6 month to 6 years,the stents were regulated or replaced one or more times in 9 cases,the stents were removed in 5 cases,and food-taking was normal following up from 6 to 36 months.Surgical operation was done in one case.The stents were retained in 6 cases,but ordinary and soft food could be taken without problem.One case was treated with 2 stes of Ni-Ti shape memory wire mesh-like stent,the esophageal stricture reappeared one month later and operation was done 6 years later.Conclusion Stent of the Z type is safe and effective in treating esophageal stricture and ulcer in children caused by corrosive injury.

Objective To study the correlations between bone fracture types and healing time in patients with osteofluorosis. Methods Thirty-seven patients with osteefluorosis and long tubular bone fracture were diagnosed in accordance with radiogram retrospectively. The fractures were divided into two groups: sclerotic and osteoporotic. Twenty four fractured patients with non osteofluorosis were included in the study as controls. All of the patients had operation(open reduction and nickelclad internal fixation). Fracture healing in patients with sclerotic and osteoporotic groups was compared with the control group after operation. Results There were notable differenees(F=4.30,P< 0.05) in term of fracture healing time among the three groups [sclerotic group:(18.4±5.3)weeks; osteoporotic group: (24.5±5.1)weeks; control group: (17.6±3.8)weeks]. Notably, there were significant differences between the osteoporotic and control groups(q=2.34,P<0.05), and between sclerotic and osteoporotic gronps(q=2.51, P<0.05). The healing time of the osteoporotic group was longer than that of sclerotic group. The constituent ratios of fracture healing in sclerotic, osteoporotic and control groups were 73.1% (19/26) ,54.5% (6/11),75.0% (18/24) respectively, and the differences among the three groups were statistically significant(X2=3.67,P<0.05). The healing rate of the osteoporotic group was lower than that of sclerotic and control groups(X2=3.12, 3.36, all P< 0.05). The constituent ratios of healing in the sclerotic, osteoporotic and control groups were 26.9% (7/26),45.5% (5/11),25.0%(6/24), respectively, and there differences among the three groups were statistically significant (X2=4.07 ,P<0.05). The delayed healing rate of the osteoperotic group was higher than those of the sclerotic and control groups(X2= 3.87,3.95, all P<0.05). Conclusions Fracture healing time of osteoporotic osteofluorosis after fracture is longer than normal, and the cause might be the loss of bone mass.

Objective To compare the whole-body equivalent doses from volumetric modulated arc therapy (VMAT) and static intensity-modulated radiotherapy (IMRT) for patients with cervical cancer.Methods Nine patients with cervical cancer admitted to our hospital in 2014 were included in this study.Both VMAT and IMRT were planned for each patient.Each patient's personal dose equivalent (Hp (10)) was measured using thermoluminescent dosimeters placed at the xiphoid process and glabella during IMRT and VMAT.The whole-body equivalent doses were estimated based on the results measured at the xiphoid process and compared between the VMAT and IMRT techniques.The paired t test was used for difference analysis.Results The Hp (10) values measured at the xiphoid process and glabella of every patient were lower for VMAT than for IMRT.At a prescribed dose of 50 Gy,if the mean Hp (10) values measured at the xiphoid process were considered to represent the whole-body equivalent doses,the whole-body equivalent doses for VMAT and IMRT were 364 mSv and 538 mSv,respectively.Conclusions VMAT results in a lower whole-body equivalent dose to patients compared with IMRT.The decreased whole-body equivalent dose delivered by VMAT may reduce the likelihood of a radiation-induced secondary malignancy.
