OBJECTIVETo investigate the carrier rate of thalasaemia among the children of 10 minority ethnic groups in 3 border states (Xishuangbanna, Dehong and Nujiang) of Yunnan Province.

METHODSA total of 6562 samples of children under 10 years old were analyzed by blood cell automatic analysis and hemoglobin electrophoresis.

RESULTSThe overall carrier frequency of thalasaemia was highest (46.2%) in Dehong, and lowest (30.6%) in Nujiang. The carrier frequency of beta-thalasaemia was the highest (40.6%) in Achang, and lowest (2.5%) in Dulong. The carrier frequency of alpha-thalasaemia was the highest (22.1%) in Dai from Xishuangbanna, followed by Dulong (19.1%).

CONCLUSIONThalasaemia carrier rates were high among the children of 10 minority ethnic groups in Yunnan. There were regional differences in their incidences. The results provide a valuable basis for thalasaemia prevention in Yunnan minorities in the three border states.

Objective To investigate the prevalence rate of thalassemia among children of 0-7 years old,from six ethnic groups in Xishuangbanna and Dehong.Yunnan province.Methods 4973 blood samples from children under 7 years old were automatically undergone blood cell count,red cell osmotic fragility and hemoglobin electrophoresis testings.Results The incidence rates of thalassaemia,β-thalassemia was 37.4%,and α-thalassaemia were 22.6%and 14.7% respectively.The thalassaemia incidence rates were significantly different among age groups but not in gender. The incidence of α-thalassaemia was decreasing along with the increase of age.while the incidence of β-thalassaemia was increasing along with the increase of age.Xishuangbanna had the higher incidence than in Dehong and the differences were significant between counties.The incidence of thalassemia of Mengla ranked the first(52.2%)in Xishuangbanna,The difierences between different regions and different nationalities were significant,with β-thalassemia of Achang ranked the first(40.6%),The incidence of α-thalassemia among Han ranked the first as 45.5% while α-thalassaemia and β-thalassemia were different in regions.α-thalassaemia and β-thalassemia were significantly different between different ethnic people in the same regions.Multiple factor analysis showed that region seemed to be a risk factor and the mother's ethnicity was a protective factor and dependent variable on thalassaemia.Conclusion The incidence of thalassaemia in Yunnan Xishuangbanna and Dehong was high among children under the age of 7 and were related to ethnic and regional differences in the areas.Specific genes were proliferated along with the extension of time.Our data provided valuable information on prevention and genetic studies on thalassaemia in the minorities of Xishuangbanna and Dehong in Yunnan province.

OBJECTIVETo investigate the epidemiological status of glucose-6-phosphate dehydrogenase (G6PD) deficiency among children from Yunnan with unique ethnic origins.

METHODSDNA samples from 11759 children were tested with fluorescent spot test, G6PD/6PGD quantitative ratio assay and hemoglobin electrophoresis.

RESULTSThe detection rate of G6PD deficiency was 2.5%, for which boys were significantly greater than girls (3.5% vs. 1.4%, P<0.05). Significant differences were also detected among children from different ethnic groups and different regions. For ethnic Han Chinese, the detection rate was 0.7%, which was lower than the majority of ethnic minorities. By regression analysis, altitude of residence and family history both have significant influence on the calculated rate.

CONCLUSIONOccurrence of G6PD deficiency seems to be influenced by gender. It also varies substantially between different ethnic groups as well as regions, e.g., more common in south. It also showed a declining trend after years of diagnosis and intervention. This survey may provide a valuable basis for counseling of G6PD deficiency in Yunnan.

Objective: To investigate the effect of capsaicin on proliferation in human hepatoma SMMC-7721 cells and its possible molecular mechanism. Method: Capsaicin (50,100,150,200,250,300 μmol·L^-1) groups and blank group were set up. The cell viability was detected by cell counting kit-8 (CCK-8) assay after SMMC-7721 cells were treated with capsaicin (50,100,150,200,250,300 μmol·L^-1) for 24, 48, 72 h. The morphological changes were observed under an inverted microscope after SMMC-7721 cells were treated with capsaicin (150,200,250 μmol·L^-1) for 24 h. The mRNA expression levels of high mobility group box 1 (HMGB1) and interleukin-6(IL-6) were measured by Real-time PCR after SMMC-7721 cells were treated with capsaicin (150,200,250 μmol·L^-1) for 24 h. The levels of HMGB1 and IL-6 in cell culture supernatant were detected by enzyme-linked immunosorbent assay(ELISA) after SMMC-7721 cells were treated with capsaicin (150,200,250 μmol·L^-1) for 24 h. Result: Compared with the blank group, there was no significant difference between 50 and 100 μmol·L^-1 capsaicin groups treated for 24, 48, 72 h; after treated with the other concentrations of capsaicin (150, 200, 250, 300 μmo·L^-1) at different time points, the proliferation inhibition rate was statistically significant (P<0.05), with significant concentration and time-dependent effect; compared with the blank group, capsaicin (150, 200, 250 μmol·L^-1) groups showed different degrees of morphological changes in SMMC-7721 cells, which became round and wrinkled, with a poor attachment and more exfoliation; compared with the blank group, the mRNA expressions of HMGB1 and IL-6 in SMMC-7721 cells of capsaicin (150, 200, 250 μmol·L^-1) groups were significantly down-regulated (P<0.05), and the secretions of HMGB1 and IL-6 were significantly decreased in the supernatant (P<0.05). Conclusion: Capsaicin inhibits cell proliferation of SMMC-7721 cells, and the possible mechanism may be related to the down-regulation of HMGB1 and IL-6 at the mRNA and protein levels.

OBJECTIVE: To compare the efficacy and muscle injury imaging between oblique lateral lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of single-segment degenerative lumbar spinal stenosis. METHODS: The clinical data of 60 patients with single-segment degenerative lumbar spinal stenosis who underwent surgical treatment from January 2018 to October 2019 was retrospectively analyzed. The patients were divided into OLIF groups and TLIF group according to different surgical methods. The 30 patients in the OLIF group were treated with OLIF plus posterior intermuscular screw rod internal fixation. There were 13 males and 17 females, aged from 52 to 74 years old with an average of (62.6±8.3) years old. And 30 patients in the TLIF group were treated with TLIF via the left approach. There were 14 males and 16 females, aged from 50 to 81 years old with an average of (61.7±10.4) years old. General data including operative time, intraoperative blood loss, postoperative drainage volume, and complications were recorded for both groups. Radiologic data including disc height (DH), the left psoas major muscle, multifidus muscle, longissimus muscle area, T2-weighted image hyperintensity changes and interbody fusion or nonfusion were observed. Laboratory parameters including creatine kinase (CK) values on postoperative 1st and 5th days were analyzed. Visual analogue scale(VAS) and Oswestry disability index(ODI) were used to assess clinical efficacy. RESULTS: There was no significant difference in the operative time between two groups(P>0.05). The OLIF group had significantly less intraoperative blood loss and postoperative drainage volume compared to the TLIF group(P<0.01). The OLIF group also had DH better recovery compared to the TLIF group (P<0.05). There were no significant differences in left psoas major muscle area and the hyperintensity degree before and after the operation in the OLIF group (P>0.05). Postoperativly, the area of the left multifidus muscle and longissimus muscle, as well as the mean of the left multifidus muscle and longissimus muscle in the OLIF group, were lower than those in the TLIF group (P<0.05) .On the 1st day and the 5th day after operation, CK level in the OLIF group was lower than that in the TLIF group(P<0.05). On the 3rd day after operation, the VAS of low back pain and leg pain in the OLIF group were lower than those in the TLIF group (P<0.05). There were no significant differences in the ODI of postoperative 12 months, low back and leg pain VAS at 3, 6, 12 months between the two groups(P>0.05). In the OLIF group, 1 case of left lower extremity skin temperature increased after the operation, and the sympathetic chain was considered to be injured during the operation, and 2 cases of left thigh anterior numbness occurred, which was considered to be related to psoas major muscle stretch, resulting in a complication rate of 10% (3/30). In the TLIF group, one patient had limited ankle dorsiflexion, which was related to nerve root traction, two patients had cerebrospinal fluid leakage, and the dural sac was torn during the operation, and one patient had incision fat liquefaction, which was related to paraspinal muscle dissection injury, resulting in a complication rate of 13% (4/30). All patients achieved interbody fusion without cage collapse during the 6- month follow-up. CONCLUSION Both OLIF and TLIF are effective in the treatment of single-segment degenerative lumbar spinal stenosis. However, OLIF surgery has obviously advantages, including less intraoperative blood loss, less postoperative pain, and good recovery of intervertebral space height. From the changes in laboratory indexes of CK and the comparison of the left psoas major muscle, multifidus muscle, longissimus muscle area, and high signal intensity of T2 image on imaging, it can be seen that the degree of muscle damage and interference of OLIF surgery is lower than that of TLIF.
