Abstract
Background Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder, characterized by progressive limb weakness, dysphagia, dysphonia, and respiratory failure due to degeneration of upper and lower motor neurons. The pathogenesis of ALS is still unclear. Neuroinflammation has been found to be involved in its development and progression. Cytokines play a significant role in the inflammatory process. This study aims to identify novel biomarkers that may assist in the diagnosis of ALS. Methods In Fujian Medical University Union Hospital and Huashan Hospital Fudan University, two independent centers, we prospectively recruited 50 ALS patients, and 41 healthy controls (25 ALS and 26 controls in the first stage and 25 ALS and 15 controls in the validation stage). An 18-plex Luminex kit was used to screen the serum cytokines levels in the first stage. Commercial ELISA kits were used to measure the levels of target cytokines in the validation stage. A single-molecule array HD-X platform was applied to assess the levels of serum neurofilament light chain (NFL). Results The levels of serum IL-18 were markedly increased in patients with ALS in the first stage (p = 0.016). The ROC curve showed an area under the curve at 0.695 (95% CI 0.50-0.84) in distinguishing ALS patients from healthy controls. The IL-21 was decreased in elderly patients when grouped by 55 years old (the medium age). Furthermore, the IL-5, IL-13, IL-18, and NFL had a positive relationship with the disease progression of ALS. We also found that serum IL-18 was markedly increased in ALS patients in the validation stage (167.67 [148.25-175.59] vs 116.44 [102.43-122.19]pg/ml, p < 0.0015). Conclusion In this study, we identified systemic cytokine profile changes in the serum of ALS patients, especially the elevated IL-18, as well as the decreased IL-21 in elder patients. These changes in serum cytokine profiles may shed new light on an in-depth understanding of the immunopathogenic characteristics of ALS.

Abstract
Background The safety of COVID-19 vaccines has been clarified in clinical trials; however, some immunocompromised patients, such as myasthenia gravis (MG) patients, are still hesitant to receive vaccines. Whether COVID-19 vaccination increases the risk of disease worsening in these patients remains unknown. This study aims to evaluate the risk of disease exacerbation in COVID-19-vaccinated MG patients. Methods The data in this study were collected from the MG database at Tangdu Hospital, the Fourth Military Medical University, and the Tertiary Referral Diagnostic Center at Huashan Hospital, Fudan University, from 1 April 2022 to 31 October 2022. A self-controlled case series method was applied, and the incidence rate ratios were calculated in the prespecified risk period using conditional Poisson regression. Results Inactivated COVID-19 vaccines did not increase the risk of disease exacerbation in MG patients with stable disease status. A few patients experienced transient disease worsening, but the symptoms were mild. It is noted that more attention should be paid to thymoma-related MG, especially within 1 week after COVID-19 vaccination. Conclusion COVID-19 vaccination has no long-term impact on MG relapse.

Abstract
Arisaema cum Bile (Dan Nanxing in Chinese, DNX) have been employed to treat allergic asthma. However, the active components and its mechanisms remain unknown. Therefore, the systematic pharmacology approach-experimental validation was performed in this study. Each 5, 6, and 10 compounds of DNX were obtained by HPLC analysis, TCMSP, and literature report, respectively. A total of 379 targets on all these compounds were acquired from Swiss Target Prediction, and 1973 targets on allergic asthma were predicated. The KEGG enrichment analysis was performed. Furthermore, a rat model of allergic asthma was established and DNX (450 mg/kg, p.o.) was given for 2 weeks. DNX treatment prevented OVA-induced pathological changes in lung cell of irregular arrange and necrotic bronchial epithelial. It also decreased inflammatory cytokines IL-4, IL-5, and IL-13 of serum and BALF, and increased IL-12 and IFN-γ. The main MAPK signaling pathway predicted by KEGG enrichment was verified, as indicated by the decreased protein expression of JNK (p < 0.05 &p < 0.01), ERK (p < 0.05), and p38 MAPK (p < 0.01) in lung tissue. These findings indicated that DNX attenuated OVA-induced allergic asthma mainly by decreasing the MAPK signaling pathway.

Abstract
Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) is a complicated maternally inherited disorder lacking of sensitive and specific biomarkers. The objective of this study was to investigate the serum neurofilament light chain (NfL) as a novel biomarker of neurological dysfunction in MELAS. Patients with different status of MELAS were enrolled in this study. The Mini-Mental State Examination (MMSE) was given to the participants to evaluate cognition status. Multiple functional MRI was performed on the participants. Blood samples were collected and the serum NfL concentrations were determined by the single-molecule array technology (Simoa). This study enrolled 23 patients with MELAS, 15 people in the acute attack phase of MELAS and 10 people in the remission phase, including 2 patients in both acute attack and remission phase. Sixteen healthy controls (HCs) were also enrolled. Serum NfL level increased significantly in patients with MELAS. Serum NfL level in the acute attack group (146.73 [120.91–411.31] pg/ml, median [IQR]) was higher than in the remission group (40.31 [19.54–151.05] pg/ml, median [IQR]) and HCs group (7.70 [6.13–9.78] pg/ml, median [IQR]) (p < 0.05). The level of NfL in the remission phase group was higher than in HCs group (p < 0.05). A negative correlation was found between the serum NfL level and MMSE (p = 0.006, r = -0.650). The NfL concentration correlated positively with stroke-like lesion volume in the brain (r = 0.740, p < 0.001). Serum NfL may serve as a novel biomarker for the neurological dysfunction in MELAS patients.

Abstract
Objective: To compare the efficacy between thymectomy plus prednisone and prednisone alone in patients with non-thymoma myasthenia gravis (MG). Methods: Thirty generalized MG patients without thymoma who underwent thymectomy were collected as the operation group, and thirty-nine patients without thymectomy who were treated with prednisone alone were matched as the control group. The start point was the enrollment time and the endpoint event was the "clinical remission" (including complete stabilization remission, drug remission, and poor performance). The survival curve was used to analyze the difference of endpoint event time between the two groups. Besides, a 12-month follow-up study was conducted to compare relevant clinical indicators between the two groups. Results: There was no significant difference in the occurrence time of endpoint events between the two groups (P=0.614). After 6-month follow-up, no significant differences were found in clinical remission rate, the dosage of pyridostigmine bromide and prednisone, the peak dosage of prednisone, the use of other immunosuppressive medications and the rate of hospitalization for exacerbation of disease between the two groups (all P>0.05). After 12-month follow-up, the dosage of prednisone and pyridostigmine in the operation group was significantly lower than that in the control group (5(0,10)mg/d vs 7.5(5,10)mg/d and 30(0,105)mg/d vs 90(15,180)mg/d; P=0.038, 0.032). Conclusion: In patients with mild to moderate non-thymoma generalized MG, thymectomy does not achieve faster remission, but it does reduce the long-term dosage of prednisone and bromopyrazine.

Abstract
Purpose: To design and screen for potential anti-malaria agents based on a series of 4-aminoquinolinyl analogues.Methods: Molecular fingerprint analysis was used for molecular partitioning of training and test sets. Acquired training sets were used for CoMFA and CoMSIA model construction after good alignment was achieved. Partial least squares analysis combined with external validation were used for model evaluation. Deep analysis of acquired contour maps was performed to summarize the substituent property requirements for further rational molecular design. Using the chosen models, activity prediction and subsequent ADMET investigation were performed to discover novel designed compounds with the desired properties.Results: Three different set partitions for model establishment were obtained using fingerprint-based selection. Partition 02 offered an optimal CoMFA model (r2 = 0.964, q2 = 0.605 and r2pred = 0.6362) and the best CoMSIA model (r2 = 0.955, q2 = 0.585 and r2 pred = 0.6403). Based on contour map analysis, a series of compounds were designed for activity prediction. Two of the compounds (wmx09, wmx25) were chosen for their ideal predicted biological activities. Subsequent ADMET investigation indicated that these compoundss have acceptable drug-like characteristics.Conclusion: The screening reveals that compounds wmx09 and wmx25 have strong potential as antimalaria agents.

Objective: To evaluate the clinical characteristics of myelin oligodendrocyte glycoprotein antibody (MOG-IgG) associated myelitis in a cohort of Chinese Han adults. Methods: From January 2016 to December 2017, 70 patients with MOG-IgG associated disorders (MOGAD) and 120 patients with aquaporin 4 antibody (AQP4-IgG) positive neuromyelitis optica spectrum disorders (NMOSD) visited the NMO/MS clinic or the neurology ward of Huashan Hospital, and the neurophthalmology clinic of Eye and ENT hospital, Shanghai Medical College, Fudan University were enrolled. The clinical and paraclinical data of the patients were retrospectively reviewed. The characteristics of MOG-IgG associated myelitis were further clarified. Results: Sixteen of the 70 patients with MOGAD had ever experienced myelitis. The frequency of myelitis was 18.6% at the first attack and 22.9% throughout the disease duration. The onset age of MOG-IgG associated myelitis was 9-57(30±11) years, and the female to male ratio was 0.6∶1. Compared with AQP4-IgG positive myelitis attacks, MOG-IgG associated myelitis attacks were more common to be accompanied by feverish prodromal symptom (30.8%) while less common to exhibit painful tonic (12.5%). Longitudinally extensive myelitis (>3 vertebral segments) was less frequent (56.3%), and short-segment myelitis and multiple short-segment myelitis could also be seen. MRI showed that MOGAD patients had more lower spinal cord lesions (20%), fewer cervical cord lesions (40%) and less transverse lesions (52%). Axial H sign was a distinct feature (36%). MOG-IgG associated myelitis attack also demonstrated a lower EDSS score after treatment. Conclusion: MOG-IgG associated myelitis should be recognized as an important clinical component of MOGAD.

Abstract
Objective: To clarify the effect of cognitive impairment on social function and quality of life of chronic schizophrenia, and provide clinical cognitive strategies for improving the social function and quality of life of patients with schizophrenia. Methods: Atotal of 158 patients with chronic schizophrenia were selected from May 2017 to October 2017 in the Psychiatry Department of the Third Affiliated Hospital of Sun Yat-sen University received psychological assessments, such as, MATRICS Consensus Cognitive Battery(MCCB), the Brief Psychiatric Rating Scale(BPRS), the Personal and Social Performance scale(PSP), and Schizophrenia Quality of Life Scale(SQLS). We further explored the effects of neurocognitive and social cognitive functions on their individual and social performance and quality of life in patients with schizophrenia. Results: (1) The scores of SQLS in the group with impaired social cognitive function were higher than those with good social function(101±46 vs 76±40, P=0.002). (2) The digital sequence and continuous performance test of the socially functional group were higher than the defect group. (3) There was a significant correlation between the years of education(R(2)=0.334, F=25.542), continuous performance (R(2)=0.316, F=35.647), BPRS (R(2)=0.280, F=60.386) and social function (P<0.001). (4) BPRS (R(2)=0.486, F=228.28), and emotional management (MSCEIT) (R(2)=0.510, F=124.789), education (R(2)=0.531, F=90.161), age (R(2)=0.539, F=69.644) significantly affected the SQLS score of patients with schizophrenia(P<0.001). Conclusion: The social function and quality of life of patients with schizophrenia are significantly correlated with their years of education and disease severity. Continuous performance in neurocognition significantly affects the social function of patients with schizophrenia, and emotional management in social cognition significantly affects their quality of life. Socially functional schizophrenia patients have higher digital sequences (working memory) and continuous performance (attention/alertness) scores.

Abstract
To reveal the extraction regularity of volatile oil from galangal by GC-MS analysis. The volatile oil in galangal was extracted by steam distillation. The extract was collected every 30 min, the oil part and the water part were separated. GC-MS was used to analyze the extraction liquid collected at different time periods. A total of 140 volatile components were obtained by GC-MS analysis. Among them, the main components were eucalyptus oil alcohol, alpha-pine oil alcohol and 4-terpene alcohol; 22 special components were dissolved in water, 77 special components were dissolved in oil and 41 components were dissolved in both oil and water. With the increase of specific components in water, the content of Eucalyptus in water increased in a linear manner. The increase of eucalyptus oil further promoted the dissolution or dispersion of alpha PN in water, and the change of specific components in oil was positively correlated with the content of Eucalyptus and alpha-terpilenol in oil. The results of principal component analysis show that the physical and chemical properties of the compounds were important factors affecting the distribution of components. PC1 (molecular weight, melting point, boiling point positive correlation), PC2 (negative correlation of refractive index) and PC3 (positive correlation of water solubility) were the main components that lead to the differences in composition distribution. The process of extracting volatile oil from galangal through steam distillation was affected by the physical and chemical properties of volatile components. Some components were specifically distributed in the fragrance and volatile oil system. The endemic components of aromatic water increased the content of the main components in the water system, which may lead to the "emulsification", reduction of the yield and low quality of the volatile oil.

Abstract
Aberrant ROCK activation has been found in patients with several autoimmune diseases, but the role of ROCK in myasthenia gravis (MG) has not yet been clearly investigated. Here, we demonstrated that ROCK activity was significantly higher in peripheral blood mononuclear cells (PBMCs) from MG patients. ROCK inhibitor Fasudil down-regulated the proportions of Th1 and Th17 cells in PBMCs of MG patients in vitro. Intraperitoneal injection of Fasudil ameliorated the severity of experimental autoimmune myasthenia gravis (EAMG) rats and restored the balance of Th1/Th2/Th17/Treg subsets. Furthermore, Fasudil inhibited the proliferation of antigen-specific Th1 and Th17 cells, and inhibited CD4 + T cells differentiated into Th1 and Th17 through decreasing phosphorylated Stat1 and Stat3, but promoted Treg cell differentiation through increasing phosphorylated Stat5. We conclude that dysregulated ROCK activity may be involved in the pathogenic immune response of MG and inhibition of ROCK activity might serve as a novel treatment strategy for MG.

Abstract
Hawthorn (CFS) has commonly been applied as an important traditional Chinese medicine and food for thousands of years. The raw material of CFS is commonly processed by stir-frying to obtain yellow (CFY), dark brown (CFD), and carbon dark (CFC) colored products, which are used for different clinical uses. In this study, an intelligent sensory system (ISS) was used to obtain the color, gas, and flavor samples data, which were further employed to develop a novel and accurate method for the identification of CFS and its processed products using principal component analysis. Moreover, this research developed a model of an artificial neural network, which could be used to predict the total organic acid, total flavonoids, citric acid, hyperin, and 5-hydroxymethyl furfural via determination of the color, odor, and taste of a sample. In conclusion, the ISS and the artificial neural network are useful tools for rapid, accurate, and effective discrimination of CFS and its processed products.

Abstract
Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) are progressive neurodegenerative disorder associated with polygenetic, maternally inherited mutations in mitochondrial DNA. Approximately 80% of MELAS cases are caused by the mutation m.3243A>G of the mitochondrial tRNA(Leu (UUR)) gene (MT-TL1). We reported two probands with MELAS features. Muscle biopsy identified ragged-red fibers (RRF) in Gomori Trichrome staining. A respiratory chain function study showed decreased activity of mitochondrial respiratory chain complex I in both probands. Sequencing of the mitochondrial DNA revealed two novel MT-ND1 gene missense mutations, m.3959G>A and m.3995A>G, which are highly conserved among species. Protein secondary structure predictions demonstrated that these mutations may alter the peptide structure and may lead to decreased ND1 gene stability. Our findings suggest that these two novel mutations may contribute to the MELAS phenotypes of the patients in our study.

Abstract
Anubias spp. are very popular aquatic plants that are native to Africa. Anubias barteri is a broadleaf Anubias and is a popular choice for aquariums because of its robust size. In China, broadleaf Anubias is usually planted in sand, with sponges around the rhizome, in small plastic baskets in aquatic plant nurseries. In December 2010, a survey of phytoparasitic nematodes was conducted in the nurseries in Guangzhou, Guangdong Province. Many second-stage juveniles of a Meloidogyne sp. were detected from the roots of A. barteri, but no root galls were found. To identify these juveniles, molecular identification was performed with PCR. The DNA sequence between CO II and l-rRNA of the mitochondrial gene of single juveniles was amplified with universal primers of Meloidogyne, #C2F3 (5'-GGTCAATGTTCAGAAATTTGTGG-3') and #1108 (5'-TACCTTTGACCAATCACGCT-3') (3). The amplified fragments were approximately 1.1 kb long and could not be digested with restrictive enzyme HinfI. The specific fragments were then sequenced. The blast search result revealed that the DNA sequence (GenBank Accession No. JQ446377) had 99 to 100% identity with submitted sequences of Meloidogyne arenaria (GenBank Accession Nos. EU364879, GQ266686, and AY635610). The other extracted juveniles were inoculated into sterile, potted, water spinach (Ipomoea aquatica) in the greenhouse to obtain more nematodes. After 40 days, root galls and female egg masses were clearly observed, and biochemical, molecular, and morphological identifications were conducted. Isoenzyme phenotype (esterase and malate dehydrogenase (MDH) patterns) and the perineal pattern of several gravid females were the same as M. arenaria (1,2), and PCR amplification of single juveniles produced identical fragments as previously found. Single egg masses were collected and juveniles were hatched out and inoculated onto 10 nematode-free plants of A. barteri in a greenhouse. After 40 days, roots of A. barteri exhibited inconspicuous small galls, and the same identification procedures were conducted as mentioned previously. Isoenzyme phenotypes, perineal patterns of adult females, and amplified fragments of single juveniles were identical to those of M. arenaria. M. arenaria is one of the most important root-knot nematodes and causes great losses in many crops around the world (2). To our knowledge, this is the first record of M. arenaria parasitizing aquatic plants of broadleaf Anubias in China and elsewhere, and A. barteri is a new host of M. arenaria. The economic importance of this nematode to A. barteri production is currently unknown. However, because A. barteri is a commercial aquatic plant, more attention should be given by producers to prevent this nematode from becoming an important pathogen. In addition, this finding is very helpful for relevant plant nematode quarantine work. References: (1) P. R. Esbenshade and A. C. Triantaphyllou. J. Nematol. 17:1, 1985. (2) R. N. Perry et al.

Abstract
During immune mediated demyelinating lesions, the endocannabinoid system is involved in the pathogenesis of both neuroinflammation and neurodegeneration through different mechanisms. Here, we explored the cellular distribution of cannabinoid 2 receptor (CB(2)R) in the central nervous system (CNS) and detected the level of CB(2)R expression during experimental autoimmune encephalomyelitis (EAE) by RT-PCR, Western blot and immunostaining. Our results show that CB(2)R was expressed in neurons, microglia and astrocytes. During EAE, the expression of CB(2)R in spinal cord rose slowly at days 9 and 17 post immunization (p.i.), and elevated rapidly at day 28 p.i., while the expression of CB(2)R in spleen elevated rapidly and got a plateau at days 17 and 28 p.i. Only the increase of CB(2)R expression in spinal cord demonstrated a significant difference when compared to control mice immunized with complete Freund's adjuvant (CFA). The selective CB(2)R antagonist (SR144528) exacerbated EAE clinical severity accompanied by weight loss. SR144528 inhibited the expression of CB(2)R, but increased the expression of CB(1)R in brain, spinal cord and spleen. The administration of SR144528 declined interferon-γ, IL-17, IL-4, IL-10, IL-1β, IL-6 and tumor necrosis factor-α, but increased CX3CL1 in brain and/or spinal cord. In contrast, IL-17 and MCP-1 were increased, while CX3CL1 was decreased in splenic mononuclear cells as compared to vehicle controls. These results indicate that manipulation of CB(2)R may have therapeutic value in MS, but its complexity remains to be considered and studied for further clinical application.

Abstract
BACKGROUND Calpainopathy is comprised of a group of myopathies caused by deficiency in calcium-activated, neutral protease (calpain-3). In this study we identify calpainopathy in a cohort of Chinese patients with unclassified myopathy and analyze its clinical and pathological features. METHODS Sixty-six muscle biopsies were selected for combined Western blotting of dysferlin and calpain-3 after immunohistochemical staining. Clinical and pathological parameters of 15 confirmed calpainopathy cases were determined. RESULTS The diagnosis of calpainopathy in 15 Chinese patients was confirmed by Western blot analysis. Fourteen subjects had progressive proximal muscle weakness; 1 presented with bilateral distal muscle atrophy of the lower extremities. Scapular winging was observed in 12 patients (80%), and joint contractures were found in 10 others (66.7%). Histopathological studies showed a high prevalence of lobulated fibers (66.7%). CONCLUSIONS Chinese patients with calpainopathy share some common clinical and pathological features with the reported characteristics of non-Chinese patients.

Abstract
BACKGROUND The role of apolipoprotein E (APOE) polymorphism has been well recognized in other cognitive neurodegenerative disorders, such as Alzheimer disease. Its role in multiple sclerosis (MS) is less clear, though studies indicate that 40% to 60% of patients with MS have evidence of cognitive impairment. OBJECTIVE To determine whether there is an association between APOE epsilon 4 and cognitive deficits in MS. METHODS We performed a standardized battery of neuropsychological tests investigating the four cognitive domains commonly impaired in MS and assessed the association of the presence of APOE epsilon 4 with cognition in MS. RESULTS A strong association was found between the presence of APOE epsilon 4 and cognitive deficits in patients with MS, particularly in the domains of learning and memory. This association was strongest in our youngest cohort (age 31 to 40) of patients with MS. CONCLUSIONS APOE epsilon 4 is significantly associated with cognitive impairment in patients with multiple sclerosis (MS). However, the modest effects do not justify APOE genotyping of patients with MS in clinical practice.

Abstract
The authors found a female patient aged 33-years with dementia and cerebellar ataxia rapidly progressing for a year. EEG tracings were abnormal but without features of typical CJD. The patient died 13 months after the onset of illness. Biopsy of her cerebral cortex showed moderate spongiform changes, neuronal loss and gliosis. Numerous deposits of eosinophilic substance amorphous or in the shape of Kuru plaques were disclosed in the cerebral cortex. All deposits stained strongly with monoclonal 3F4 antibody to human prion protein. Genetic studies disclosed the Pro to Leu point mutation at codon 102 with a 102 Leu-129 Met in the PrP gene. Codon 129 was heterozygous for Met/Val, and codon 219 was homozygous for Glu/Glu. It was established; moreover, that the patient's grandfather had a similar disease and died at age 48 and the patient's brother died after a 10-year long neurological disease diagnosed as hereditary cerebellar ataxia. On the basis of clinical, neuropathological and genetic findings, the authors diagnosed the Gerstmann-Sträussler-Scheinker disease, a familial prion disease with an autosomal dominant character. This is the first report on this disease in China.

Abstract
BACKGROUND CD4(+)CD25(+) regulatory T cells are key controllers of peripheral immunological self-tolerance and suppress various autoimmune diseases in animal models, but few studies have been done to define their roles in myasthenia gravis (MG) so far. OBJECTIVE To investigate frequencies and dynamic changes of blood CD4(+)CD25(+) T cells from MG patients. METHODS The peripheral blood CD4(+)CD25(+) T cells of 29 MG patients and 23 healthy controls were detected by three-color flow cytometry. RESULTS Myasthenic patients with symptomatically uncontrollable disease showed slightly lower percentages of CD4(+)CD25(+) T cells (mean = 3.79 +/- 1.40%; P = 0.12), whereas MG patients with clinically stable disease had significantly increased CD4(+)CD25(+) T cells (mean = 8.45 +/- 1.96%, P = 0.0001), as compared with healthy controls (mean = 4.53 +/- 0.96%). In addition, thymectomized MG patients had significantly higher percentages of CD4(+)CD25(+) T cells (mean = 8.44 +/- 2.39%), as compared with both non-thymectomized MG patients (mean = 5.88 +/- 2.89%, P = 0.038) and healthy controls (P = 0.003). CONCLUSIONS Our observations indicate that increased percentages of CD4(+)CD25(+) T cells in MG patients may be related to disease stability and that thymectomy in patients with MG resulted in augmented CD4(+)CD25(+) T cells.

Abstract
The effect of serum starvation and olomoucine treatment on the cell cycle and apoptosis of goat skin fibroblasts cultured in vitro is reported in this paper. The cells were obtained from the ear of a female goat 1.5 years of age. Analysis of cell cycle distribution by fluorescence-activated cell sorting (FACS) showed that 3.4, 60.8 and 15.1% of normally cycling cells were at G1, G0 and S phase, respectively. Serum starvation for 1, 3 and 5 days arrested 70.1, 70.2 and 83.4% cells, respectively, at G0/G1 phase. Seventy-eight percent of confluent cells were at G0/G1 stage, but in contrast to the serum starved group, this high percentage of G0/G1 cells was mainly associated with G1 cells. Of cells not deprived of serum, 73.6% were arrested at G1/G0 when treated with 100 microM olomoucine for 9 h compared to 85.5% of cells that had been starved of serum for 2 days (co-inhibition) (P<0.01). After co-inhibition, 45% of cells entered S phase when re-cultured in normal medium for 5 h, indicating that the inhibition was reversible. Under normal culture conditions, 1.2% of cells underwent apoptosis. Serum starvation for 1, 2, 3, 5 and 10 days caused apoptosis in 1.7, 3.9, 4.5, 11.7 and 90.3% of cells, respectively. Treatment with 100 microM olomoucine for 9h did not increase the number of apoptotic cells significantly (1.9%, P>0.05). When cells were co-inhibited, 4.1% of cells underwent apoptosis. In conclusion, although serum withdrawal for 5 days or more effectively arrested cells at G0/G1 stages, it increased apoptosis of cells significantly. However, co-inhibition by serum withdrawal and olomoucine treatment was found to be an appropriate treatment to obtain more healthy G0/G1 cells based on the low percentage of apoptotic cells after treatment.

Abstract
A total of 38 pairs in each group (observed group and controlled groups) were selected. A comparison was also make between the observed group and the 29 no-smokers. Based on the statistical data of 18 pulmonary function tests obtained in the present study, the author suggested that FVM, FVV and BR% were rather highly sensitive in defecting abnormal change in pulmonary function.
