Seven emotions generation relates to the interaction between individual and external objective matters,which is accompanied with interaction between internal desire and external matters.The activity of seven emotions bases on essence of zang-fu organs,being regulated by five zang viscera.Heart is the upstream controller,liver is the key organ to maintain normal emotionds,spleen and stomach is the hub of emotional activities,lung is the auxiliary organ, kidney is origin of emotional generation.Five zang viscera's cooperation and interaction generate the seven emotions.

Abstract: Objective　To investigate the prevalence and genetic characterization of Blastocystis in primary and middle school students in Baisha Li Autonomous County, Hainan Province, in order to understand the infection status of Blastocystis and its subtype distribution characteristics in this area. Methods　From March to November 2021, fecal samples were collected from two primary and middle schools in Baisha Li Autonomous County. Nested PCR targeting the SSU rDNA was employed in this study, sequence analysis were performed to determine the prevalence and subtype. A neighbor-joining tree was built using Mega 7. Meanwhile, the risk factors of the Blastocystis infection among different grades and genders were evaluated. Results　The infection rate of Blastocystis was 4.1% (13/314), there was no statistical difference in infection rates among genders and grades (P>0.05). Sequence analysis revealed that three Blastocystis subtypes were identified, namely ST3 (n=7), ST7 (n=4) and ST1 (n=2), all of which have zoonotic potential. Conclusions　This is the first report of the identification of Blastocystis in humans in Hainan at the subtype level, and provide the basic data for the prevention and control of Blastocystis in this area. The zoonotic subtypes identified in this area indicated more studies should be taken in humans and various animals, to better evaluate the transmission of Blastocystis and provide scientific support for the prevention and control of Blastocystis.

A total of 180 type 2 diabetic patients with negative anti-thyroid autoantibodies were recruited.According to the levels of serum 25-OH vitamin D [25 (OH) D],these patients were divided into four groups:sufficient group (≥ 30 ng/ml),insufficient group (20-＜30 ng/ml),deficiency group (10-＜20 ng/ml),and severe deficiency group(＜ 10 ng/ml).The results showed that compared with sufficient vitamin D group,the group with severe deficient vitamin D had higher TT3,FT3,FT3/FT4,and TSH (all P＜0.05).The serum 25(OH) D level was negatively correlated with TSH values (r =-0.207,P＜0.05) after adjustment for gender,age,and body mass index.Multivariate regression analysis indicated that serum 25 (OH) D level was an independent influencing factor for TSH value (β =-0.201,P＜0.05),suggesting that serum 25 (OH) D level seems to be correlated with thyroid function in type 2 diabetic patients.

The association between thyroglobulin gene polymorphism and autoimmune thyroid disease was investigated.A total of eight case-control studies were included.E33SNP was associated with increased susceptibility of autoimmune thyroid disease in recessive model (OR =1.54,95 ％ CI 1.21 ～ 1.97,P =0.024),while E12SNP was associated with increased susceptibility of autoimmune thyroid disease in allele model (OR =1.12,95％ CI 1.05 ～1.21,P =0.033).Thyroglobulin gene polymorphism seems to be associated with autoimmune thyroid disease.

Objective To explore the value of hydrogen sulfide(H2S) in the evaluation of severity of acute pancreatitis(AP).Methods Fifty-one patients with AP from February 2013 to December 2015 in this hospital were divided into severe acute pancreatitis (SAP,n=21) group and mild acute pancreatitis (MAP,n 30) group.Thirty six non-pancreatitis abdominal patients and 9 healthy persons(NC) were chosen as compare groups.The peripheral venous blood samples from the four groups and the Ranson Score of AP group were obtained after admission,the venous blood samples of 12 h,24 h,48 h of AP group were also obtained.Blood samples were used to detect the concentrations of hydrogen sulfide with ELISA method.We compared the concentrations of H2S between the four groups with one way ANOVA,and post hoc;compared the differences of concentrations of H2S in AP group between after admission,12 h,24 h and 48 h with repeated measures data ANOVA;and explored the relationship between the concentrations of H2S after admission and the Ranson scores in AP group with Spearman correlation analysis.Results The concentra tions of H2S was significant higher in SAP group than MAP,abdominal,and NC group(P=0.000);the concentrations of H2S was also significant higher in MAP group than abdominal,and NC group(P=0.000);there is no significant difference between the abdominal and NC group(P =0.131).There is significant difference of H2S concentrations between the four times in AP group(P =0.000),decreasing gradually over time.The H2S concentrations in AP group after admission was significantly related with their Ranson scores(r=0.578,P=0.000).Conclusion There is certain value of the concentrations of H2S in the diagnosis of AP,the higher H2S level suggests the higher severity of the patients with acute pancreatitis.

Objective To investigate the effects of anti-adhesion treatment and high-strength suture technique on the treatment of extensor tendon rupture by animal experiments and clinical application.Methods Twenty-eight leg-born chickens were randomly divided into four groups(7 each).Double cross suture was applied in group A,while double cross suture combined with sodium hyaluronate spraying in group B,cross-finger-like micro-braided suture in group C,and cross-finger-like micro-braided suture combined with sodium hyaluronate spraying in group D.The animals were sacrificed 6 weeks after operation,morphological,histological and biomechanics were observed and compared among the groups.One hundred and sixteen patients were treated with the surgical method in group D(89 males,27 females,aged 20-55 with an average of 36 years;73 with extensor tendon rupture,38 with strain/chalasis,5 with firearm injuries;56 on back of hand,48 on central slip,12 on lateral fixing chorda;82 with one-stage operation,and 34 with second-stage operation),and then followed-up for 2-5 years to observe the therapeutic effects.Results The repaired tendons in group D was in good contour,most tendon cells arranged regularly in bunches.The maximum load was significantly higher in group D(70.9?5.7N) than in group A(48.4?5.7N),Group B(51.3?3.2N) and Group C(68.3?2.8N,P

cDNA for Insulin-like growth factor binding protein 3 was cloned and constructed a prokaryotic expression vector--pET-DsBA-IGFBP3. The construct was transformed into E. coli BL21 (DE3)plysS. The induced fusion protein (D-IGFBP3) was expressed successfully in soluble form. We obtained D-IGFBP3 the purify of which is over 95% after purification by His affinity chromatography. The product was identified by Western-blot. The cell assay showed that the obtained fusion protein can inhibit the growth of MCF-7 and bind with IGF-I in vitro.

Objective To explore the effect of L-carnosine on neuronal cell apoptosis in young rats with experimental febrile seizures(FS).Methods Forty 15-day SD rats were randomly divided into intervention group(n=30)and FS group(n=10).Warm water was used to induce 10 times FS.The intervention group was divided into E,G and H group,10 rats in each group.Intraperitoneal injection of L-carnosine(250 mg/kg)was separately given to the rats in E group,G group and H group respectively after 30,60 and 120 min of seizure.FS group were induced FS,but they were not given intervention.The rats were sacrificed at 12 hours after the last seizure.Neuronal cell apoptosis was determined by terminal eoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL)in situ cell death kit.TUNEL positive cells were stained and counted as apoptosis in hippocampus and cortex.Ultrastructural changes of apoptosis neurons were observed under the electron microscope.Results The neuronal cells apoptosis count was 25.37?1.95 in FS group,12.36?1.13 in E group,17.85?2.04 in G group,and 22.69?2.69 in H group.Neuronal apoptosis of FS group was apparently higher than that of interventional groups(F=10.75 P0.05).Under the electron microscope,neuronal damage on hippocampal CA1 area and dentate gyrus of FS group and H group was obviously higher than that of E group.Conclusions Early injection of L-carnosine would not only relieve neuronal apoptosis of repeated FS,but also play a role in the protection of neuronal cells.
