Abstract
Objective: To investigate the application value of augmented reality navigation combined with indocyanine green(ICG) fluorescence imaging technology in laparoscopic anatomical segment 8 liver resection. Methods: Clinical and pathological data from 8 patients with hepatocellular carcinoma located in segment 8 of the liver admitted to the First Department of Hepatobiliary Surgery,Zhujiang Hospital,Southern Medical University from October 2021 to October 2022 were collected restrospectively. Among them,there were 5 males and 3 females,aged between 40 and 72 years. During the operation,the self-developed laparoscopic augmented reality surgical navigation system was used to integrate the three-dimensional liver model with the laparoscopic scene,and ICG fluorescence imaging technology was used to guide the anatomical liver resection of segment 8. The predicted liver resection volume and actual liver resection volume,related surgical indicators and postoperative complications were analyzed. Results: Among the 8 patients, 4 underwent laparoscopic anatomical segment 8 liver resection,1 underwent laparoscopic anatomical ventral subsegment of segment 8 liver resection,2 underwent laparoscopic anatomical ventral subsegment combined with medial subsegment of segment 8 liver resection, and 1 underwent laparoscopic anatomical dorsal subsegment of segment 8 liver resection. All operations were completed under the guidance of augmented reality navigation combined with ICG fluorescence imaging,without conversion to open surgery. The operation time was (276.3±54.8)minutes(range:200 to 360 minutes). Intraoperative blood loss was (75.0±35.4)ml(range:50 to 150 ml). No blood transfusion was performed during the operation. The length of postoperative hospital stay was (7.6±0.8)days(range:7 to 9 days). There were no deaths or postoperative complications such as bleeding or biliary fistula during the perioperative period. Conclusion: Augmented reality navigation combined with ICG fluorescence imaging technology can guide the implementation of laparoscopic anatomical segment 8 liver resection.

Abstract
Objective: To explore the characteristics and prognostic value of pulmonary hemodynamics in patients with acute coronary syndrome (ACS). Methods: From a prospective multicenter registry study of pulmonary hypertension due to left heart disease, consecutive ACS patients who underwent coronary angiography in combination with left and right heart catheterization during hospitalization between January 2013 and November 2016 were involved. The primary endpoint was all-cause mortality. The prognostic variables identified by the Lasso analysis were included in the Global Registry of Acute Coronary Events (GRACE) score. Model performance was evaluated before and after the addition of hemodynamic parameters. Results: A total of 251 patients were enrolled, with age of (63.7±11.5) years. A total of 198 males (78.9%) and 53 females (21.1%) were recruited, and the median follow-up time was 34.7 months. Right heart catheterization-assessed mean pulmonary arterial pressure (mPAP), systolic pulmonary arterial pressure (sPAP) and diastolic pressure gradient (DPG) were found to be significant predictors for survival in ACS. Adjusted for age and sex, the adjusted HR (95%CI) of mPAP, sPAP and DPG were 1.068 (1.015-1.123), 1.033 (1.002-1.065) and 1.094 (1.008-1.187), respectively (P<0.05). Applied to the present cohort of 251 patients, the median of the GRACE score was 123 points, with a C-index of 0.703 (95%CI: 0.615-0.791) for predicting mortality. After the addition of mPAP or DPG to the GRACE score, the C-index increased to 0.715 (95%CI: 0.629-0.801) or 0.711 (95%CI: 0.625-0.797), respectively. When comparing two models before and after the addition of mPAP or DPG, the integrated discriminatory index (IDI) was 4.3% (95%CI: 0.2%-13.5%, P=0.030) and 3.0% (95%CI: 0.2%-11.1%, P=0.020), respectively. Conclusion: Pulmonary hemodynamics can be predictive for survival in ACS patients, providing incremental prognostic value to risk assessment in ACS.

Abstract
Molecular markers can increase both the efficiency and speed of breeding programs. Functional markers that detect the functional mutations causing phenotypic changes offer a precise method for genetic identification. In this study, we used newly derived cleaved amplified polymorphic sequence markers to detect the functional mutations of tms5, which is a male sterile gene that is widely used in rice production in China. In addition, restriction cutting sites were designed to specifically digest amplicons of tms5 but not wild type (TMS5), in order to avoid the risk of false positive results. By optimizing the condition of the polymerase chain reaction amplifications and restriction enzyme digestions, the newly designed markers could accurately distinguish between tms5 and TMS5. These markers can be applied in marker-assisted selection for breeding novel thermo-sensitive genic male sterile (TGMS) lines, as well as to rapidly identify the TGMS hybrid seed purity.

Abstract
In order to understand the effect of grain moisture of inbred lines at the silking and physiological maturity stages on kernel dehydration rate, 59 maize inbred lines from six subgroups were selected. Grain moisture was measured and QTLs associated with kernel dehydration were mapped. A rapid dehydration evaluation and association analysis revealed eight inbred lines with faster dehydration rate, including Yuanwu 02, K36, Zhonger/O2, Lo1125, Han 49, Qi 319, Hua 160, and PH4CV. A single sequence repeat analysis using 85 pairs detected five QTLs with phenotypic variation contribution ≥10% in the permanent F2 generation populations Zheng 58 x S1776 and Chang 7-2 x K1131, which had LOD threshold values ≥ 3 in both 2013 and 2014. The chromosome region of qFkdr7b had not previously been reported and is preliminarily identified as a new major QTL. A false positive field verification of grain dehydration rate of 53 inbred lines indicated that the screening result of the rapid dehydration inbred lines by specific amplification with marker Phi114 was most similar to the field assessment result, followed by markers Phi127 and Phi029. The rapid dehydration lines selected based on primer Phi114 amplification were also similar to the field dehydration rate and can thus be used for molecular marker-assisted selection. A significant effort is needed to improve stress resistance and shorten the growth period via fast kernel dehydration in intermediate materials of the inbred lines K36, Zhonger/ O2, Lo1125, Han 49, Hua 160, and PH4CV, and further using the selected lines for new combinations.

Abstract
Tobacco germplasm samples with various levels of resistance to bacterial wilt were selected to construct F1 combinations of parental inbred lines and orthogonal diallel crosses using samples collected in 2009 (15 germplasms), 2010 (15 germplasms), and 2011 (16 germplasms). A total of 1/2P (P + 1) experimental materials were used for analysis. Based on the analyses of major and minor locus groups, genetic effects on the incidence rate and index of bacterial wilt in tobacco were investigated on the 15th and 25th day during the early stage. Significant effects were observed in major locus groups, but not in minor locus groups. Specifically, adjacent major locus groups (J1 = 13,056 and J1 = 13,055; J1 = 14,080 and J1 = 14,079) were detected in both the first and second analyses with considerable effects. Based on the additive effects of minor locus groups on the rate and index of bacterial wilt, the effects on the incidence rates of Yunyan 85, DB101, and RG11 as well as the effects on the disease index of the latter two germplasms reached the maximum. This was consistent with the disease resistance indicators of these tobacco varieties in the field (corresponding broad heritability >20%). Genetic homozygous dominant loci (+ +) increased the rate of bacterial wilt (susceptible), whereas homozygous recessive loci (- -) reduced the index of bacterial wilt (resistant) with considerable additive effects and low dominant effects, suggesting that the inheritance of the bacterial wilt rate and index in tobacco mainly relies on additive inheritance.

Abstract
BACKGROUND The objective of this study was to explore the potential for vertical transmission of hepatitis B virus (HBV) from parents to offspring via human germ cells. METHODS For study samples, 250 oocytes from hepatitis B surface antigen (HBsAg) seropositive women and 578 embryos from couples with at least one HBsAg seropositive partner were collected. HBV DNA in the nuclei of oocytes and embryos was detected by fluorescence in situ hybridization; HBsAg expression was analysed using immunofluorescence; and serum HBV DNA levels were measured by real-time PCR. The HBV infection duration of the women and the serum HBsAg status of their mothers were also examined. RESULTS HBV DNA was present in 9.6% (24/250) of oocytes and 14.4% (83/578) of embryos. Rates of HBV DNA positive embryos were similar among couples in which the woman, man or both partners were HBsAg seropositive, 13.1% (57/436), 21.3% (16/75) and 14.9% (10/67), respectively. Rates of positivity in oocytes and embryos were significantly higher in a group with high serum levels HBV DNA than in a group with lower serum levels (P= 0.004 and P= 0.002, respectively). Higher rates of oocyte positivity were found for women whose mothers were HBV infected compared with those with uninfected mothers. Expression of HBsAg was observed in 8.7% (2/28) oocytes and 14.1% (10/71) embryos (P= 0.34). CONCLUSIONS The presence of HBV DNA in human oocytes or embryos was related to the women's serum levels of HBV DNA and the infection status of their mothers. The HBV positive embryos were either maternally or paternally dependent. HBV infection may result in vertical transmission to the offspring via germ cells.

Abstract
Experiments to document the long-term effects of clipping management on N requirements, soil organic carbon (SOC), and soil organic nitrogen (SON) are difficult and costly and therefore few. The CENTURY ecosystem model offers an opportunity to study long-term effects of turfgrass clipping management on biomass production, N requirements, SOC and SON, and N leaching through computer simulation. In this study, the model was verified by comparing CENTURY-predicted Kentucky bluegrass (Poa pratensis L.) clipping yields with field-measured clipping yields. Long-term simulations were run for Kentucky bluegrass grown under home lawn conditions on a clay loam soil in Colorado. The model predicted that compared with clipping-removed management, returning clippings for 10 to 50 yr would increase soil C sequestration by 11 to 25% and nitrogen sequestration by 12 to 28% under a high (150 kg N ha(-1) yr(-1) nitrogen (N) fertilization regime, and increase soil carbon sequestration by 11 to 59% and N sequestration by 14 to 78% under a low (75 kg N ha(-1) yr(-1)) N fertilization regime. The CENTURY model was further used as a management supporting system to generate optimal N fertilization rates as a function of turfgrass age. Returning grass clippings to the turf-soil ecosystem can reduce N requirements by 25% from 1 to 10 yr after turf establishment, by 33% 11 to 25 yr after establishment, by 50% 25 to 50 yr after establishment, and by 60% thereafter. The CENTURY model shows potential for use as a decision-supporting tool for maintaining turf quality and minimizing negative environmental impacts.

Abstract
A cDNA fragment (fragment 9) has been isolated by mRNA differential display and antisense technology in this lab, and its relevant gene (fragment 9 related gene, FNR gene) might be involved in the inhibition of non-targeted mutagenesis induced by N -methyl- N ' -nitro-N-nitrosoguanidine(MNNG) in mammalian cells. In order to elucidate the functional mechanism of the FNR gene, the protein expression was compared between MNNG-exposed Vero cells transfected with antisense RNA expression plasmid (Vero-pM-amp(-)-9(-)) and those with vector DNA (Vero-pM-amp(-)), by using two-dimensional gel electrophoresis followed by 2D image software analysis. Our analysis indicated that 12 proteins were specifically expressed only in Vero-pM-amp(-)-9(-), and 2 proteins in Vero-pM-amp(-). In addition,there were 24 proteins expressed in higher level in Vero-pM-amp(-)-9(-) as compared with Vero-pM-amp(-)( P <0.05), among them the expression of 7 proteins were enhanced by greater than 5 folds. These results suggest that antisense blocking the FNR gene expression triggered a series of alteration of other gene expression and the FNR gene might be a regulatory factor. This study will also facilitate the identification and characterization of these proteins and corresponding genes involved in the non-targeted mutagenesis.

Abstract
AIM: To clone the cDNA of UGT1A9 from a Chinese human liver and establish the Chinese hamster lung (CHL) cell line expressing human UGT1A9.
METHODS: cDNA of UGT1A9 was transcripted from mRNA by reverse transcriptase-ploymerase chain reaction, and was cloned into the pGEM-T vector which was amplified in the host bacteric E. coli DH5α. The inserted fragment, verified by DNA sequencing, was subcloned into the Hind III/Not I site of a mammalian expression vector pREP9 to construct the plasmid termed pREP9-UGT1A9. CHL cells were transfected with the resultant recombinants, pREP9-UGT1A9, and selected by G418 (400 mg•L¯¹) for one month. The surviving clone (CHL-UGT1A9) was harvested as a pool and sub-cultured in medium containing G418 to obtain samples for UGT1A9 assays. The enzyme activity of CHL-UGT1A9 towards propranolol in S9 protein of the cell was determined by HPL C.
RESULTS: The sequence of the cDNA segment cloned, which was 1666 bp in length, was id entical to that released by GeneBank (GenBank accession number: AF056188) in co ding region. The recombinant constructed, pREP9-UGT1A9, contains the entire coding region, along with 18 bp of the 5’ and 55 bp of the 3’ untranslated region of the UGT1A9 cDNA, respectively. The cell lines established expressed the protein of UGT1A9, and the enzyme activity towards propranolol in S9 protein was found to be 101 ± 24 pmol•min-1•mg-1 protein (n = 3), but was not detectable in parental CHL cells.
CONCLUSION: The cDNA of UGT1A9 was successfully cloned from a Chinese human liver and transfected into CHL cells. The CHL-UGT1A9 cell lines established efficiently expressed the protein of UGT1A9 for the further enzyme study of drug glucuronidation.

Abstract
OBJECTIVE To investigate the different expression of actin, myosin II in hypertrophic scars, keloids and normal skins, and to understand the relationship of actin, myosin II and the scar contracture. METHODS Fifteen cases with hypertrophic scars, 10 cases with keloids and 15 cases with normal skins were chosen randomly. The expression of actin and myosin II were detected by immunohistochemical method in the hypertrophic scars, keloids and normal skins. The fibroblasts isolated from three types of tissue were cultured in vitro, then actin and myosin II in three different fibroblasts were measured using flow cytometry. RESULTS The immunohistochemical staining of myosin II in hypertrophic scars was positive, while the staining in keloids and normal skins were negative. The positive rate of myosin II expression in hypertrophic scars, keloids and normal skins were (95.11 +/- 2.78)%, (16.86 +/- 7.11)%, and (5.31 +/- 1.79)% respectively. There were significant difference between keloids and the two others(P < 0.01). The actin expression in three difference tissues were positive, there were no significant difference in hypertrophic scars, keloids and normal skins(P > 0.05). The positive rate of actin expression in hypertrophic scars, keoids and normal skins were(77.77 +/- 15.43)%, (88.89 +/- 10.29)%, and (82.92 +/- 13.48)% respectively, and there were no significant difference(P > 0.05). CONCLUSION Myosin II may play an important role in the scar contracture. Actin is the contractile protein of cell, it plays important role in cellular movement. Actin is necessary protein in the cell.

Abstract
OBJECTIVE To study the relationship between intracellular actin and scar contracture. METHODS Fibroblasts from 10 cases of hypertrophic scar and 5 cases of keloid were cultured in vitro. Total actin, filamentous actin(F actin), globular actin (G actin) and the ratio of F to G actin(F/G) were measured by densitometry after differential extraction and separation by polyacrylamide gel electrophoresis in the presence of sodium sulfate. RESULTS Total actin, F actin, G actin and F/G in hypertrophic scar fibroblasts were 2.38 ng/10(4) cells, 0.98 ng/10(4) cells, 1.42 ng/10(4) cells and 0.68 respectively, while in keloid fibroblasts were 1.68 ng/10(4) cells. 0.46 ng/10(4) cells, 1.26 ng/10(4) cells, and 0.36 respectively. There was significant differences between two tissues fibroblasts in the items of total actin, F actin, G actin, and F/G (P < 0.01), while no significant difference in G actin (P > 0.05). CONCLUSION Total intracellular actin, F actin, and F/G may play an important role in the scar contracture. The hypertrophic scar and keloid can be distinguished by the contents of total intracellular actin, F actin and F/G.

Abstract
The island flap based distally on the posterior interosseous artery has been proven to be available for the correction of severe cicatricial contracture deformity of the ipsilateral hand. However, the main disadvantages of this flap are the second donor area deformity and muscle or tendon adhesions after skin grafting. Both these complications may be ameliorated by means of tissue expansion to obtain a secure blood supply to the flap. The surgical procedure has been performed in 7 patients with satisfactory result since August 1989.

Abstract
Chloroquine (CQ) solution was separately mixed with the serum of mice infected with chloroquine-resistant 'NS' line (SMNS), the serum of mice infected with chloroquine-sensitive Plasmodium berghei ANKA strain (SMCS), and the serum of normal mice (SM). These mixtures were then used in treating mice inoculated with P. berghei ANKA strain. The results obtained on d 5 after drug-serum administration showed that the erythrocyte infection rates in the SMNS + CQ, SMCS + CQ, and SM + CQ groups were 32, 16, and 14% respectively. There were significant differences with respect to parasitemia between the SMNS + CQ group and the SMCS + CQ or SM + CQ group (P less than 0.05), suggesting that SMNS may be antagonistic to the antimalarial action of chloroquine. Further study showed that when the 'NS' line lost resistance to chloroquine, the antagonism of SMNS to chloroquine disappeared. The antagonism rates of SMNS to chloroquine, piperaquine, hydroxypiperaquine and pyronaridine were 75, 56, -5, and -17% respectively, a trend similar to that of the results from cross-resistance tests on chloroquine-resistant P. berghei ANKA strain. The results indicate that drug-resistant malaria parasites may produce and release a certain 'specific anti-drug substance'.
