Objective To observe the changes of abdominal oxygen saturation in very low birth weight infants (VLBWI)with feeding intolerance (FI)within 1 4 days after birth monitored by near infrared spectroscopy (NIRS).Methods VLBWI fitting entry criteria were enrolled into this study.NIRS monitoring was carried out to detect cerebral oxygen saturation (ScO2 )and abdominal oxygen saturation (SsO2 ).Data were analyzed between FI infants and feeding tolerance (FT)infants.FI was defined as follows:gastric residual of more than 50% of the previous feeding volume;emesis or abdominal distention or both;decrease,delay or discontinuation of enteral feedings. Results 93 VLBWI were enrolled.52 cases(55.91 %)presented with FI,including 29 cases(31 .1 9%)of gastric residual increasing and 23 cases(24.73%)of emesis with or without abdominal distention within 1 4 days after birth. The levels of SsO2 and SsO2 /ScO2 showed no differences in infants with FT and with FI within 24h after birth (P >0.05).The change rates of the median of SsO2 and SsO2 /ScO2 in FT infants were similar during 1 4 days (P >0.05).While both the change rates of SsO2 and SsO2 /ScO2 were markedly decreased 1 day before and the day of FI (P <0.01 ).The decreasing degree of SsO2 was similar between infants with gastric residual increasing and infants with emesis with or without abdominal distention[(1 6.2 ±5.1 )vs (1 7.4 ±3.6)%,t =0.733,P =0.476]. Conclusion Abdominal oxygen saturation measured by NIRS may be a useful method for infants adjusting the feeding plan.

Objective:To analyze clinicopathological characteristics of trauma-related melanoma and their relationship with the prognosis of patients.Methods:Clinical data were collected from 87 cases of trauma-related melanomas in Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from 2009 to 2020, and their clinicopathological characteristics were retrospectively analyzed. Mann-Whitney test was used to analyze the difference in Breslow thickness of tumors between patients of different ages or genders; Spearman rank correlation analysis was used to analyze the correlation between the time from trauma to the notice of melanoma and Breslow thickness, Kaplan-Meier survival analysis and Log-Rank test were employed to analyze the relationship between clinicopathological characteristics of melanoma and the prognosis of patients; Cox regression model was used to analyze risk factors for survival duration of patients with trauma-related melanoma.Results:Among the 87 patients with trauma-related melanoma, 47 (54.02%) were males and 40 (45.98%) were females. Among them, melanoma occurred in 50 (57.47%) cases after sharp injuries, and in 37 (42.53%) after blunt injuries. In addition, 31 (35.63%) cases presented with primary lesions on the hands, and 48 (55.17%) on the feet. The Breslow thickness of the primary tumors was significantly higher in the group aged > 55 years than in the group aged ≤ 55 years ( U= 623.500, P= 0.010) , but there was no significant difference between patients of different genders ( P= 0.138) . The time from trauma to the notice of melanoma was negatively correlated with the Breslow thickness of tumors ( r=-0.203, P= 0.037) . The age of patients, Breslow thickness of tumors, Ki67 proliferation index and genetic background of tumor significantly affect the survival duration of patients with trauma-related melanoma ( P= 0.011, 0.031, 0.002 and 0.031, respectively) ; the gender, type of trauma and ulceration of tumor mass did not significantly affect the survival duration of patients ( P= 0.618, 0.114 and 0.379, respectively) . Cox regression model analysis showed that the Ki67 proliferation index and Breslow thickness were independent risk factors affecting the prognosis of trauma-related melanoma (risk ratio [ RR] and 95% confidence interval [ CI] were 1.946 (1.234, 4.217) and 1.839 (1.014, 3.332) , P= 0.039 and 0.045, respectively) . Conclusion:The Breslow thickness of trauma-related melanoma is related to the age of patients and time from trauma to the notice of melanoma; the age, Breslow thickness of tumors, Ki67 proliferation index and genetic background of tumor all affect the survival duration of patients with melanoma, and Ki67 proliferation index and Breslow thickness are independent risk factors affecting prognosis.

OBJECTIVETo assess the association of BDNF gene Val66Met polymorphism with efficacy of antidepressant treatment and plasma BDNF level.
METHODSTwo hundred and forty-nine ethnic Han Chinese patients with depression(study group), who have met the diagnostic criteria of DSM-IV, were prescribed with venlafaxine or paroxetine. Two hundred and two healthy individuals were recruited as the control group. General demographic information such as gender, age, educational status, occupation, and marriage status were collected. HAMD-17 was adopted as the primary rating tool to evaluate the severity of depression on the baseline and at the end of 1st, 2nd, 4th, 6th week of treatment. PCR-restriction fragment length polymorphism was applied to determine the Val66Met polymorphism of the BDNF gene in the two groups. Plasma BDNF concentration was measured with ELISA before and after 6 weeks of treatment.
RESULTSNo significant differences have been found in HAMD scores and reduction of HAMD scores on the baseline and at the end of 1 st, 2nd, 4th, 6th weeks of treatment for each genotype. Nor were significant differences found in the Val66Met genotypes and allelic frequency between patients who achieved remission or not after 6 weeks' treatment as well as the healthy volunteers. The plasma BDNF level in depression patients was lower than that in healthy controls. The BDNF level has increased significantly after 6 weeks' treatment with both venlafaxine and paroxetine, but was still lower than the healthy controls. The BDNF level in the patients achieved remission who were treated with venlafaxine was similar to the normal controls, while those treated with paroxetine was still lower than normal controls. The BDNF level in patients who have not achieved remission was lower than normal controls. The BDNF level was not associated with the Val66Met polymorphism on the baseline and the end of 6th week.
CONCLUSIONNo association has been found between the efficacy of venlafaxine or paroxetine and the BDNF Val66Met polymorphism. The BDNF level of patients with depression is significantly lower than healthy controls on the baseline, and can be enhanced with the treatment. Particularly, the BDNF level in patients who achieved remission after the treatment of venlafaxine can rise to normal. The level of BDNF has certain value in the forecasting of efficacy in the anti-depression therapy. BDNF level is not associated with the Val66Met polymorphism of the BDNF gene.

OBJECTIVETo explore hematological and molecular characteristics of Hemoglobin Q-Thailand in Huizhou area of Guangdong Province.
METHODSA total of 34 977 samples were screened by capillary and agarose gel electrophoresis. Samples suspected with HbQ strips were subjected to blood cell count and DNA sequencing. Twenty three common mutations associated with α- and β-thalassemia were identified by liquid phase chip and diversion hybridization technique.
RESULTSThe carrier rate of Hb Q-Thailand in Huizhou area was 0.13%. Pedigree analysis indicated that the Hb Q-Thailand allele is linked with a leftward single a-globin gene deletion (-α). Hematological index (HGB, MCV, MCH, HbA, HbA, HbQ) of 45 heterozygous carriers of Hb Q-Thailand were (130.25±17.37) g/L, (79.81±4.97) fl, (26.38±1.48) pg, (71.37±5.07)%, (1.65±0.45)%, (26.87±4.95)%, respectively. A statistical difference was also found in their hematological index of HbA and HbA compared with 408 heterozygous carriers of -α mutation (P<0.05).
CONCLUSIONHb Q-Thailand has a high detection rate in Huizhou area. The allele is mainly in a heterozygous status and linked with -α. The Hb Q strip can be detected by hemoglobin electrophoresis. When combined with other types of thalassemia, the heterozygotes will show unique hematological parameters.
