Abstract: Objective To analyze the changes of coagulation indicators in patients with hepatitis B complicated with Clonorchis sinensis (C. Sinensis), and provide reference value for diagnosis, drug using and prognosis monitoring. Methods The patient samples were collected from the Third Affiliated Hospital of Sun Yat-sen University from June 2018 to February 2022 and divided into six groups. They were 40 healthy patients, 47 patients with simple chronic hepatitis B, 47 patients with post-hepatitis B liver cirrhosis, 40 patients with C. Sinensis mono-infection, 30 patients with chronic hepatitis B patients co-infected with C. Sinensis and 27 patients with post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis. Four coagulation indexes, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB), were detected and compared among the groups. Results Compared with the healthy group, C. Sinensis mono-infection group had higher level of FIB and delayed PT, APTT; chronic hepatitis B group and chronic hepatitis B patients co-infected with C. Sinensis group had delayed PT, APTT, TT and significant lower FIB, these differences were statistically significant (all P<0.05). Compared with simple chronic hepatitis B group, post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Compared with the post-hepatitis B liver cirrhosis and chronic hepatitis B patients co-infected with C. Sinensis, post-hepatitis B liver cirrhosis patients coinfected with C. Sinensis group had significant delayed PT, APTT, TT and lower FIB (all P<0.05). Conclusions The coinfection of C. Sinensis will further aggravate the coagulation dysfunction of HBV patients, leading to poor treatment and prognosis. HBV patients will have worse coagulation function in the process to post-hepatitis B liver cirrhosis; Therefore, it is important to pay attention to C. Sinensis co-infection when treating HBV patients, so that further guidance on clinical use and monitoring of prognosis can be provided.

Two patients with coexistence of thyroid disease and suspected Gitelman's syndrome underwent SLC12A3 gene analysis. The results confirmed that both patients were compound heterozygotes of SLC12A3 gene mutation. Three novel variants of SLC12A3 were found in this study. This report suggests that Gitelman's syndrome may coexist with other disorders associated with hypokalemia, such as Graves' disease.

AIM:To evaluate the clinical characteristics in retinal nerve fiber layer ( RNFL) thickness of the 8~17 years old near sightedness, provide the basis for juvenile glaucoma diagnosis, to avoid missed diagnosis and misdiagnosis.
METHODS:A total of 165 eyes from 99 healthy subjects ( age range 8 ~ 17 years ) were divided into low, moderate, high myopia and normal group. Cirrus HD OCT was used to measure the RNFL thickness. Each subject was performed circular scans around the optic nerve with a circle size of 3. 46mm. Total average, mean quadrant and clock - hour RNFL thicknesses were recorded and compared between the four groups. The characteristics of the RNFL thickness of myopia were observed.
RESULTS: Compared myopia groups with normal group, the mean RNFL thickness decreased, there was statistically significant difference in high myopia group (P<0. 05). The mean RNFL thickness of superior, inferior and nasal quadrant decreased, temporal quadrant was thickened. Compared moderate and high myopia groups with normal group, superior, inferior quadrant RNFL thickness were thinning, temporal quadrant was thickening, the differences had statistical significance ( P< 0. 05 ). The RNFL measurements were statistically significant thinner in the myopia groups compared with normal group at 1:00, 5:00, 6:00 and 12:00 o'clock ( P<0.05) and thicker at 8:00, 9:00, 10:00 o'clock (P<0. 05). The RNFL measurement was statistically significant thicker in the low myopia group compared with normal group at 3:00 o'clock (P<0. 05).
CONCLUSION: Compared adolescent myopia with normal, the Avg ( mean RNFL thickness ) , S ( superior quadrant RNFL thickness ) , I ( inferior quadrant RNFL thickness), 1:00, 5:00, 6:00 and 12:00 o'clock RNFL thickness is thinner, which is decreased with the increasing SE. While the temporal ( T) quadrant, 8:00, 9:00, 10:00 o'clock RNFL thickness is thicker, which increased with the increasing SE. Analysis of RNFL thickness in the evaluation of glaucoma should always be interpreted with reference to the refractive status, so as not to cause misdiagnosis of glaucoma. The highest diagnosis efficiency position of glaucoma is infratemporal (7:00~8:00 o'clock) and superior temporal (10:00 ~11:00 o'clock), which is not thinner in juvenile myopia, if these positions become thinner, it may be the possibility of glaucoma.

Objective: Cell cycle has recently become more appealing as a new target of anti-carcinogen-ic agent. Diallyl disulfide (DADS) inhibits growth and induces call cycle G_2/M arrest in human gastric cancer BGC823 cells. Cell division cycle protein 25C (Cdc25C) and CyclinB1 expression are involved in G_2/M arrest.However, mechanisms of G_2/M arrest are not yet fully understood. The aim of this study was to elucidate the mechanism of cell cycle G_2/M arrest in human gastric cancer BGC823 cells induced by DADS. Methods: The expression of chk1 and Chk2 mRNA associated with cell cycle arrest of BGC823 cells after the induction with DADS for 1 or 2 days was detected by RT-PCR. The protein expression of cycle-related proteins ATM-RAD3-related gene (ATR), checkpoint kinase1 (Chk1), checkpoint kinase 2 (Chk2), P-ATR, P-Chk1 and P-Chk2 was measured by Western blot. Interaction between Chk1/2 and Cdc25C was analyzed by immuno-precipitation. Results: After the cells were treated with 15 mg/L DADS for 1 or 2 days, the expression of Chk1 and Chk2 mRNA was not significantly different from that in untreated cells (P>0.05). Western blot analysis showed that the expression of total Chk1 and Chk2 treated with 15 mg/L DADS was not significantly different from that in untreated cells. But phospho-chk1 showed a significant increase after stimulation with 15 mg/L DADS for 2h to 12h and continued to increase gradually as time went on (P<0.05). Phospho-Chk2 showed a eak expression and a weaker expression after stimulation with DADS, but the changes were not statistically significant (P>0.05). Addition of 15 mg/L DADS to BGC823 cells for 15 rain to 120 min resulted in an increase in phospho-ATR expression, whereas no changes were found in ATR expression (P<0.05). The Chk1 Ab in-creasingly precipitated Cdc25C in BGC823 cells treated with DADS (P<0.05). In contrast, Chk2 Ab failed to change precipitation with Cdc25C by DADS (P>0.05). Conclusion: Activation of chk1 was involved in cell cy-cle G_2/M arrest in BGC823 cells treated with DADS. Cell cycle G_2/M arrest by DADS is associated with phos-phorylation of several cell cycle regulatory proteins including ATR and Chk1 which regulate expression of Cdc25C.

In this study, the COI barcode was used to identify the Scolopendra medicinal materials and its adulterants in order to provide a new method for the identification of Scolopendra. Genomic DNA was extracted from the experimental samples. The COI sequences were amplified and sequenced bi-directionally. Sequence alignment and NJ tree construction was carried out by MEGA6.0 software. The results showed that the COI sequences can be obtained from all experimental samples. The average inter-specific K2P distance of Scolopendra was 0.222 and the minimum inter-specific distance was 0.190. All the Scolopendra subspinipes mutilans medicinal samples clustered into a clade in the NJ tree and can be distinguished from its adulterants. In a conclusion, COI can be used to correctly identify Scolopendra medicinal materials, and it will be a potential DNA barcode for identifying other animal medicinal materials.
