Abstract
BACKGROUND Patients rarely develop complicated infections in thyroid cysts. Here, we describe a patient with chronic infected unilateral giant thyroid cyst related to diabetes mellitus (DM). CASE SUMMARY A 66-year-old male was admitted due to an evident neck lump for 5 d after approximately 40 years of gradually progressive neck mass and 7 years of DM. Doppler ultrasound and computed tomography scan showed a giant lump in the left thyroid gland lobe. He was diagnosed with a large thyroid nodule complicated by tracheal dislocation and had surgical indications. Surgical exploration revealed evident inflammatory edema and exudation between the left anterior neck muscles, the nodule and glandular tissue. Fortunately, inflammatory lesions did not affect major neck vessels. Finally, a left partial thyroidectomy was performed. Macroscopic observation showed that the cystic thyroid mass consisted of extensive cystic wall calcification and was rich in massive rough sand-like calculi content and purulent matter. Postoperative pathology confirmed benign thyroid cyst with chronic infection. CONCLUSION The progression of this chronic infectious unilateral giant thyroid cyst may have been related to DM, and identifying blood vessels involvement can prevent serious complications during operation.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of blonanserin and risperidone for the treatment of schizophrenia and to provide reliable pharmacotherapeutic evidence for in the clinical treatment of schizophrenia. METHODS We systematically searched the PubMed, Cochrane Library, Embase, Chinese Biomedical Literature Database (CBM), and China National Knowledge Infrastructure (CNKI) databases for head-to-head randomized controlled trials that compared blonanserin with risperidone for the treatment of schizophrenia. We extracted the following data: author, year, country, diagnostic criteria, sample size, course of treatment, dosage and outcomes. Our main endpoint was the changes in the Positive and Negative Syndrome Scale (PANSS) total scores. Meta-analysis of the included data was conducted by RevMan 5.3 software. We used the GRADE criteria to evaluate the certainty of the evidence. RESULTS A total of 411 studies were initially; 8 trials were eligible and were included in our analysis (N = 1386 participants). Regarding efficacy, there was no difference in changes in the PANSS total scores between the two groups (P > 0.05). In terms of safety, compared to risperidone, the incidence of serum prolactin increases and weight gain in the blonanserin group was lower (P<0.05), but the incidence of extrapyramidal symptoms (EPS) was higher (P<0.05). CONCLUSION The efficacy of blonanserin is similar to that of risperidone, but it is unclear whether blonanserin is more effective than risperidone at improving cognitive and social function. More high-quality studies are needed to verify the efficacy and safety of blonanserin in the future.

Abstract
Objective This meta-analysis of randomized clinical trials (RCTs) was conducted to explore the therapeutic effects, tolerability and safety of repetitive transcranial magnetic stimulation (rTMS) as an adjunct treatment in adolescents with first-episode major depressive disorder (FE-MDD). Methods RCTs examining the efficacy, tolerability and safety of adjunctive rTMS for adolescents with FE-MDD were included. Data were extracted by three independent authors and synthesized using RevMan 5.3 software with a random effects model. Results A total of six RCTs involving 562 adolescents with FE-MDD were included. Adjunctive rTMS was superior in improving depressive symptoms over the control group [standardized mean difference (SMD) = -1.50, 95% confidence interval (CI): -2.16, -0.84; I2 = 89%, p < 0.00001] in adolescents with FE-MDD. A sensitivity analysis and two subgroup analyses also confirmed the significant findings. Adolescents with FE-MDD treated with rTMS had significantly greater response [risk ratio (RR) = 1.35, 95% CI: 1.04, 1.76; I2 = 56%, p = 0.03] and remission (RR = 1.35, 95% CI: 1.03, 1.77; I2 = 0%, p = 0.03) over the control group. All-cause discontinuations were similar between the two groups (RR = 0.79, 95% CI: 0.32, 1.93; I2 = 0%, p = 0.60). No significant differences were found regarding adverse events, including headache, loss of appetite, dizziness and nausea (p = 0.14-0.82). Four out of six RCTs (66.7%), showed that adjunctive rTMS was more efficacious over the control group in improving neurocognitive function (all p < 0.05). Conclusion Adjunctive rTMS appears to be a beneficial strategy in improving depressive symptoms and neurocognitive function in adolescents with FE-MDD. Higher quality RCTs with larger sample sizes and longer follow-up periods are warranted in the future.

Abstract
Schizophrenia is associated with an increased risk of metabolic syndrome (MetS), which is an important risk factor for developing cognitive impairment in the general population. A few case-control studies have explored the relationship between MetS and cognitive deficits in individuals with schizophrenia but with inconsistent findings. This meta-analysis of case-control studies was carried out to explore the association between MetS and cognitive performance in patients with schizophrenia. Only case-control studies assessing the association of cognitive function and MetS in patients with schizophrenia were identified. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) scale. Six case-control studies (n = 992) comparing cognition between patients with schizophrenia with MetS (n = 426) and those without MetS (n = 566) using the RBANS were identified. Compared to patients with schizophrenia without MetS, patients with schizophrenia and MetS had significantly more impairments in RBANS total scores [standardized mean difference (SMD) = -0.26, 95% confidence interval (CI): -0.51 to -0.02; I2 = 72%; p = 0.03], immediate memory (SMD = -0.32, 95% CI: -0.54 to -0.10; I2 = 66%; p = 0.005), attention (SMD = -0.29, 95% CI: -0.56 to -0.02; I2 = 77%; p = 0.03), and delayed memory (SMD = -0.24, 95% CI: -0.46 to -0.03; I2 = 64%; p = 0.03). No group difference was found regarding visuospatial skills and language (p > 0.05). This meta-analysis found that schizophrenia patients with MetS had worse performance on certain cognitive tasks than non-MetS patients.

Abstract
Findings of multi-session transcranial direct current stimulation (tDCS) as an adjunctive treatment of neurocognitive dysfunction in schizophrenia have been inconsistent. This meta-analysis of randomized controlled trials (RCTs) investigated the neurocognitive effects of adjunctive multi-session tDCS for schizophrenia. Twelve RCTs covering 418 schizophrenia patients were included and analyzed in this meta-analysis. The RevMan software (Version 5.3) was used to calculate risk ratios (RRs) and standardized mean differences (SMDs) with their 95% confidence intervals (CIs). Adjunctive tDCS outperformed the comparator in improving working memory deficits (SMD = 0.34, 95% CI: 0.03, 0.65; I2 = 52%; p = 0.03), but no significant effects were found in other cognitive domains. No group differences were found with regard to total psychopathology measured by the Brief Psychiatric Rating Scale and the Positive and Negative Symptom Scale (SMD =-0.29, 95%CI: -0.61, 0.03; I2 = 50%, p = 0.07) and discontinuation due to any reason (RR=0.80, 95%CI: 0.39, 1.66; I2 = 9%, p = 0.56). Adjunctive tDCS appears to have a significant therapeutic effect improving the working memory deficits in schizophrenia.

Abstract
Objective: To assess the health status and health service utilization of children born to syphilis infected mothers during pregnancy, in order to prevent mother-to-child transmission of syphilis to the newborns. Methods: Women with maternal syphilis were studied by trained researchers via phone calls, in Shanghai during 2014-2015. Data related to demographics, status of infection and health care, utilization by both mothers and their children were collected through specifically designed questionnaires. Non-parametric tests including chi-square were used to assess the health status and health service utilization of children born to mothers with different demographic and socioeconomic characteristics. Results: A total of 495 children born to mothers with maternal syphilis were recruited from 1 000 syphilis infected parturient women. A total of 61 out of the 495 children were diagnosed as having congenital syphilis (57 children were diagnosed at birth and another 4 were diagnosed during the follow-up period). Children born to women who received syphilis treatment during pregnancy were at lower risk on congenital syphilis (χ(2)=7.214, P=0.027). 37.8% of the children were reported to have had different illnesses in the past three months, mainly involving upper respiratory infections (32.3%) or diarrhea (3.6%). Children diagnosed with congenital syphilis showed a higher prevalence of different kinds of diseases, compared to those without congenital syphilis (47.5% vs. 36.6%). 81.6% of the children had received regular child health care services. Subjects with the following factors as: being immigrant, with lower education, unemployed, unmarried and multipara, were related to the less use of regular child healthcare services. Only 39.7% of the parents would inform the care-takers about the risk of congenital syphilis infection of their own children at the child health care centers. Mothers with residency of Shanghai, having higher education level and employed, were less willing to inform doctors about the risk of congenital syphilis infection of their children. Conclusions: Loss to follow-up among children born to syphilis infected pregnant women remained a serious problem. Few parents would be willing to inform the healthcare takers that their children are at risk of syphilis, when receiving child health care services at the centers. It was necessary to integrate the congenital syphilis follow-up programs into the routine child care services so as to timely diagnose and treat the patients with congenital syphilis.

Abstract
Alteration of visual scanpaths under emotional facial expression in schizophrenia patients has been described in recent years; however, it is not clear whether such results are different when they transfer to faces in natural social scenes. The present study was designed to investigate the effects of emotional faces in natural social scenes on the gaze patterns of patients with schizophrenia, compared to gaze at isolated faces. A novel theme identification task was used where participants selected a positive, neutral or negative word to describe an emotional picture. Participants were 29 patients with schizophrenia and 31 healthy controls. The Positive and Negative Syndrome Scale (PANSS) and the Scale of Social Function in Psychosis Inpatients (SSPI) were used to assess symptoms and social functioning. In total, patients with schizophrenia showed significantly fewer fixations, saccades numbers and decreased fixations in areas of interest. As expected, patients showed shorter scanpath length, but only in the pictures with social settings. Furthermore, the effect size of scanpaths parameters under social scene was all greater than isolated face. In addition, patients compared to controls showed more abnormal scanpath parameters processing negative and neutral faces than positive faces, especially in social scene. The present study suggests that scanpath length for social scene faces may be more sensitive than for isolated face pictures. Our findings further support restricted scanpath whilst recognizing emotional facial expressions in natural social scenes as a favorable topic for further investigation as a trait marker.

Abstract
Antipsychotic-induced dyslipidemia could increase the risk of cardiovascular diseases. This is a meta-analysis of randomized double-blind placebo-controlled trials to examine the efficacy and safety of adjunctive metformin for dyslipidemia induced by antipsychotics in schizophrenia. The standardized mean differences (SMDs) and risk ratios (RRs) with their 95% confidence intervals (CIs) were calculated using the random-effects model with the RevMan 5.3 version software. The primary outcome was the change of serum lipid level. Twelve studies with 1215 schizophrenia patients (592 in metformin group and 623 in placebo group) were included and analyzed. Adjunctive metformin was significantly superior to placebo with regards to low density lipoprotein cholesterol (LDL-C) [SMD: -0.37 (95%CI:-0.69, -0.05), P = 0.02; I2 = 78%], total cholesterol [SMD: -0.47 (95%CI:-0.66, -0.29), P < 0.00001; I2 = 49%], triglyceride [SMD: -0.33 (95%CI:-0.45, -0.20), P < 0.00001; I2 = 0%], and high density lipoprotein cholesterol [SMD: 0.29 (95%CI:0.02, 0.57), P = 0.03; I2 = 69%]. The superiority of metformin in improving LDL-C level disappeared in a sensitivity analysis and 80% (8/10) of subgroup analyses. Metformin was significantly superior to placebo with regards to decrease in body weight, body mass index, glycated hemoglobin A1c, fasting insulin, and homeostasis model assessment-insulin resistance (P = 0.002-0.01), but not regarding changes in waist circumference, waist-to-hip rate, leptin, fasting glucose, and blood pressure (P = 0.07-0.33). The rates of discontinuation due to any reason [RR: 0.97 (95%CI: 0.66, 1.43), P = 0.89; I2 = 0%] was similar between the two groups. Adjunctive metformin could be useful to improve total cholesterol and triglyceride levels, but it was not effective in improving LDL-C level in schizophrenia.

Abstract
OBJECTIVES This is a meta-analysis of randomized double-blind controlled-placebo trials (RCTs) examining the effectiveness, tolerability, and safety of intranasal esketamine in treating major depressive disorder (MDD). METHODS Standardized mean difference (SMD), risk ratio (RR) and their 95% confidence intervals (CIs) were calculated using RevMan version 5.3. RESULTS Four RCTs with 7 active arms covering 708 patients with MDD on intranasal esketamine (n = 419) and placebo (n = 289) were included. Compared with placebo, adjunctive intranasal esketamine was associated with significantly greater study-defined response (RR=1.39, 95%CI: 1.18 to 1.64, P<0.0001) and remission (RR=1.42, 95%CI: 1.17 to 1.72, P = 0.0004) at endpoint assessment. Intranasal esketamine had greater study-defined response starting at 2 h (RR= 2.77, 95%CI: 1.62 to 4.76, P = 0.0002), peaking at 24 h (RR=5.42, 95%CI: 1.38 to 21.20, P = 0.02), and at least lasting for 28 days (RR=1.36, 95%CI: 1.16 to 1.58, P = 0.0001). Similarly, intranasal esketamine had significantly greater study-defined remission starting at 2 h (RR=7.71, 95%CI: 2.16 to 27.55, P = 0.002), peaking at 24 h (RR=6.87, 95%CI: 1.55 to 30.35, P = 0.01), and lasting for 28 days (RR=1.38, 95%CI: 1.11 to 1.72, P = 0.004). Intranasal esketamine had a significantly higher rate of discontinuation due to intolerability (RR=3.50, 95%CI: 1.38 to 8.86, P = 0.008). Discontinuation due to any reasons and inefficacy were similar between the two groups. CONCLUSION Intranasal esketamine appears to have an ultra-rapid antidepressant effect for MDD, at least lasting for 28 days. The long-term therapeutic effect and safety of intranasal esketamine need to be further examined in large-scale RCTs.

Abstract
In this work, we report a facile, sensitive, selective, and reproducible DNA impedimetric sensor device. We demonstrate that, combined with exonuclease III, the easily prepared electrochemically reduced graphene oxide (rGO) could be a desirable platform to amplify signals in electrochemical impedance spectroscopy for ultrasensitive DNA detection. Guided by enzyme assisted target recycling, efficient interfacial tuning can be obtained, from the situation with high impedance caused by single-stranded DNA probes directly adsorbed onto rGO to the one with low impedance due to the continuous desorption of target-probe DNA hybrids and the consequent digestion of DNA probes. Just a few DNA targets can specifically trigger the enzymatic digestion of a large number of DNA probes. It is the excellent electrical conductivity of rGO that further enlarges the changes of electron transfer resistance after the removal of DNA probes. As a result of synergistically combining both enzymatic and electrical amplification, the enlarged changes of impedimetric signals can be measured to sensitively report DNA targets. The specificity has been guaranteed by the intrinsic recognition of hybrids through both rGO and exonuclease III. A limit of detection as low as 10 aM target DNA in the matrix of cell culture medium, as well as a wide linear range and good discrimination of mismatched sequences even at the one-base level, suggests its great application prospect in biosensing and biomedical analysis. It also has other advantages including easy operation, low cost, and convenient regeneration, with more competitive performance in developing impedimetric biosensors.

Abstract
Abnormal high mobility group protein B1 (HMGB1) activation is involved in the
pathogenesis of pulmonary fibrosis. Pulmonary rehabilitation mixture (PRM), which
combines extracts from eight traditional Chinese medicines, has very good lung
protection in clinical use. However, it is not known if PRM has anti-fibrotic
activity. In this study, we investigated the effects of PRM on transforming growth
factor-β1 (TGF-β1)-mediated and bleomycin (BLM)-induced pulmonary fibrosis in
vitro and in vivo. The effects of PRM on TGF-β1-mediated
epithelial-mesenchymal transition (EMT) in A549 cells, on the proliferation of human
lung fibroblasts (HLF-1) in vitro, and on BLM-induced pulmonary
fibrosis in vivo were investigated. PRM treatment resulted in a
reduction of EMT in A549 cells that was associated with attenuating an increase of
vimentin and a decrease of E-cadherin. PRM inhibited the proliferation of HLF-1 at an
IC50 of 0.51 µg/mL. PRM ameliorated BLM-induced pulmonary fibrosis in
rats, with reduction of histopathological scores and collagen deposition, and a
decrease in α-smooth muscle actin (α-SMA) and HMGB1 expression. An increase in
receptor for advanced glycation end-product (RAGE) expression was found in
BLM-instilled lungs. PRM significantly decreased EMT and prevented pulmonary fibrosis
through decreasing HMGB1 and regulating RAGE in vitro and in
vivo. PRM inhibited TGF-β1-induced EMT via decreased HMGB1 and vimentin
and increased RAGE and E-cadherin levels. In summary, PRM prevented experimental
pulmonary fibrosis by modulating the HMGB1/RAGE pathway.

Abstract
Rheumatic heart disease (RHD) remains a serious cardiovascular disorder across the world. Tumor necrosis factor alpha (TNF-α) codifies a potent immunomodulator and pro-inflammatory cytokine that mediates diverse pathological processes. A promoter 308G>A polymorphism in TNF-α has been implicated in RHD risk. However, the results remain controversial. Therefore, to evaluate more precise estimations of the relationship, a meta-analysis was performed. A total of 7 studies including 735 RHD cases and 926 controls were involved in this meta-analysis. Overall, our results revealed that there was a significant association with RHD risk in three genetic models (homozygous model: OR = 3.06, 95%CI = 1.22–10.60, P = 0.020; dominant model, OR = 2.03, 95%CI = 1.01–4.07, P = 0.048; and recessive model, OR = 4.26, 95%CI = 2.41–7.55, P < 0.001). Further ethnic population analysis found a significantly increased risk of RHD among Asians and Europeans. Interestingly, similar results were found among hospital-based studies. Begg's funnel plot and Egger's test did not reveal any publication bias. Taken together, this meta-analysis demonstrates that the TNF-α 308G>A polymorphism is associated with RHD susceptibility, and it contributes to the increased risk of RHD. However, additional well-designed studies with larger samples are warranted to confirm these findings.

Abstract
BACKGROUND The case-fatality rate for tuberculosis (TB) remains high in China, whereas risk factors for deaths among TB cases are still unclear. DESIGN This was a retrospective cohort study of all pulmonary TB patients registered in four districts of Shanghai from 2004 to 2008. Data were derived from the China National TB Surveillance System. A total of 4271 patients were followed up in communities. Data were analysed using Cox regression. RESULTS The percentage of all-cause deaths in the study population was 15% 2-6 years after the most recent TB diagnosis. TB was responsible for only 17% of all deaths; male sex was significantly associated with all-cause deaths. After adjustment for sex, age and treatment history, four factors were significantly and independently associated with increased risk of death: psychopathy, chronic bronchitis, cancer and the presence of multiple diseases. TB was responsible for 7.2 potential years of life lost (PYLL); PYLL was higher in females (8.2) than males (5.3). CONCLUSIONS TB remains a significant problem in urban China. Implementation of improved clinical management, prevention strategies and other public health programmes should target TB patients with chronic conditions, particularly those with multiple diseases.

Abstract
The epidermal growth factor (EGF) is a member of the growth factor superfamily that can stimulate the proliferation of many types of cells. Overexpression of EGF receptor (EGFR) was observed in many types of cancer cells. Anti-EGFR antibodies or antisense nucleic acid sequences of EGFR can suppress the growth of hepatoma cells. In order to further investigate the proteome alterations associated with malignant growth of the human hepatoma cells and the influence of EGFR signal pathway on the cellular proteome, we have comparatively analyzed the proteomes of human hepatoma cells transfected with antisense EGFR sequence (cell strain JX-1) and its control cells (cell strain JX-0) by two-dimensional (2-D) gel electrophoresis and mass spectrometry. Image analysis of silver-stained 2-D gels revealed that 40 protein spots showed significant expression changes in JX-1 cells compared to JX-0 cells. Three of them, including the tumor suppressor protein maspin, changed with tendency to the normal levels. Two protein spots were identified as HSP27 in the same gel, and one of them had a reduced level in JX-1 cells. The apparent alterations of HSP27 in expression level might be the results from their differential chemical modifications, suggesting the effect of dynamic post-translational modifications of proteins on the growth of hepatoma cells. Other proteins such as glutathione peroxidase (GPX-1) and 14-3-3-sigma also exhibited altered expression in JX-1 cells, and their functional implications are discussed.

Abstract
AIM To investigate inhibitory effects of recombinant transforming growth factor alpha-Pseudomonas exotoxin 40 fusion protein (TGFalpha-PE40; TP40) on neointimal proliferation after arterial balloon injury. METHODS Forty male rabbits fed a cholesterol rich diet were randomly divided into TP40 15 microg, 30 microg, 60 microg, physiologic saline control, and normal artery groups (n=8). Rabbits in the treatment groups were treated by local administration of TP40 (15 microg, 30 microg, and 60 microg per rabbit) 24 h postinjury, and those in the control group were treated by physiologic saline 24 h postinjury. Remained 8 rabbits in normal artery group were treated by TP40 (60 microg). Optical microscope, electron microscope, and computer image analysis were used to study arterial segments 2 weeks after treatment. RESULTS Irregular thickening of the arterial intima, large amounts of smooth muscle cells (SMC) within the neointima, and stenosis of the arterial cavity were observed in the physiologic saline control group. Great inhibition of intimal proliferation and prevention of stenosis of the arterial cavity were observed in the TP40 treated groups that were examined 2 weeks postinjury by optical microscope. The uninjured carotids were histologically normal. Lots of destructural and necrotic SMC were observed in media in TP40 60 microg group by electron microscope. Computer image analysis showed that the neointimal area of the TP40-treated groups was markedly smaller than that of the saline control group (P < 0.01). CONCLUSION Recombinant TP40 greatly inhibited neointimal proliferation after arterial balloon injury.

Abstract
AIM To study inhibitory effect of recombinant transforming growth factor alpha-Pseudomonas exotoxin fusion protein (TP40) on proliferation of the cultured vascular smooth muscle cells (SMC). METHODS Expression of epidermal growth factor receptor (EGFR) mRNA and EGFR in cultured proliferating and quiescent SMC was analyzed with Northern blot and immunohistochemistry. Inhibitory effects of TP40 on SMC proliferation and protein synthesis were analyzed with crystal violet staining and [3H]leucine incorporation. Competition assays were performed by the addition of 100-fold excess of EGF. RESULTS Expression of EGFR mRNA and EGFR in rapidly proliferating SMC increased than that in quiescent SMC. When the concentration of TP40 was 10 or 100 micrograms.L-1, inhibitory effects of TP40 on rapidly proliferating SMC proliferation and protein synthesis were much higher than that on quiescent SMC (P < 0.01), and the IC50 of [3H]leucine incorporation against rapidly proliferating and quiescent SMC were 8.01 (5.05-12.69) and 121.95 (90.98-163.47) micrograms.L-1. Excess EGF completely blocked inhibitory effects of TP40. CONCLUSION The rapidly proliferating SMC express EGFR at a high level. TP40 selectively inhibited the proliferation of rapidly proliferating SMC. The cytotoxic effects of TP40 were specifically mediated by EGFR.

Abstract
Recombinant plasmid pYX382 and pYX3825 were constructed by fusing the cDNA encoding transforming growth factor type alpha (TGF alpha) to Pseudomonas exotoxin gene (PE) in which the cell recognition domain was deleted. The chimeric proteins produced by host E. Coli cells BL21 transformed by plasmid pYX382 and pYX3825 are termed TGF alpha-PE 40 which reacts with antibody against TGF alpha or antibody against PE in immunoblotting to show a 46 kd protein band reflecting the fusion of 56 kD TGF alpha peptide and 40 kD truncated Pseudomonas exotoxin molecule. An additional signal sequence OmpA was inserted into upstream region of TGF alpha cDNA in plasmid pYX3825 resulting in the partly secreting of expression product into medium and periplasm of the cells. TGF alpha-PE 40 was purified from medium by MONO Q ion exchange column and TSK 250 gel filtration column attached to Pharmacia EPLC system. The TGF alpha-PE 40 molecules showed a very strong activities inhibiting the protein synthesis and killing the cancer cells overexpressing EGF receptor on the cell surface.

Abstract
Epidermal growth factor receptor (EGFR) gene expression and growth stimulation of EGF on human hepatoma cells of cell lines BEL-7404 and SMMC-7721 were studied. 125I-EGF binding assay was used to measure the binding characteristics and the amounts of EGFR on these cells. The binding time course and the binding competition assay showed that the binding of 125I-EGF to 7404 cells was saturable and specific. Scatchard analysis of EGF binding curve indicated that 7404 and 7721 cells expressed approximately 1.1 x 10(5) and 0.7 x 10(5) EGFRs per cell with binding affinity (Kd) 2.1 nM and 1.8 nM respectively. Northern hybridization and immunoblotting analysis showed the EGFR gene expression products in 7404 and 7721 cells were 5.6 Kb mRNA and 170 Kilo-dalton glycoprotein. Anchorage-dependent growth of 7404 and 7721 cells was stimulated in the presence of nanogram quantities of EGF in medium containing 10% calf serum or 0.5% calf serum. The factors in serum appeared to act synergitically in stimulating of cell proliferation. EGF also stimulated the anchorage-independent growth of 7404 and 7721 cells in soft agar. The results suggest that EGFR is actively expressed in human hepatoma 7404 and 7721 cells and EGF may be one of the mitogens needed for the growth of hepatoma cells.

Abstract
Hepatitis B virus (HBV) DNA in leucocytes from 50 hepatitis patients with various patterns of HBV serological markers and serum HBV DNA and 13 normal controls were examined by Southern blot hybridization with 32P-labeled 3.2 Kb HBV DNA. A free form of HBV DNA was observed in leucocytes of 8 patients, 7 of whom were positive for serum HBeAg, and in 6 patients an integrated form of HBV DNA was identified. HBV DNA was not identified in leucocytes from 13 normal controls. The free form of HBV DNA in leucocytes existed as a heterogeneous smear from 2.0 to 3.2 Kb, similar to the pattern in liver and hepatocellular carcinoma cells but different from serum HBV DNA in which the 3.2 Kb band was absent. The banding pattern of the integrated form of HBV DNA in leucocytes varied among different patients. During preparation of white blood cells and purification of HBV DNA probes, it was important to remove plasma contamination and traces of pBR322, respectively. The presence of extrachromosomal DNA sequences partially homologous to pBR322 could cause false results. The presence of a free and integrated form of HBV DNA in leucocytes is important for explaining the biology of HBV, the harbouring and replication sites of extrahepatic origin, the mechanism of recurrent infection, and the rationale of the treatment of hepatitis B.
