BACKGROUND: Mechanic pressure could cause neurocyte death. Both direct mechanic injury and complex pathophysiological mechanism can induce the pathological changes of axon and neuronal soma. OBJECTIVE: To observe the relationship between ultrastructural changes and pressure degree of neurocyte and neurocyte damage. DESIGN: A randomized controlled observational study using experimental animals as study subjects.MATERIALS:The study was conducted in the Central Laboratory of Ruikang Hospital affiliated to Guangxi Traditional Chinese Medical University from December 2002 to August 2003.SUBJECTS:Fourty-eight male New Zealand rabbits with a bodymass of (2.45 ± 0. 28) kg were randomly divided into control group, mild pressure group and severe pressure group with 16 rabbits in each group.METHODS:Animal models with mild and severe cervical spinal cord chronic pressure were established in rabbits. Control group was pseudo-operation group. Spinal cord observation under optical microscope and electron microscope, neurocyte apoptosis analysis (TUNEL method), neuron counting, and the section size of the neuron were analyzed respectively.MAIN OUTCOME MEASURES: Main results: observational results under optical microscope of each group. Subordinate results: ① observational results under electron microscope of each group; ② neurocyte apoptosis analysis RESULTS: After chronic pressure in the spinal cord of rabbits, phenomena like neuron atrophy,loss,reduced section size,and neuron and neurocyte apoptosis appeared. The morphology of neurons in control group was normal and the quantity was quite a lot, which was (40 ± 2), and the neuron section size was(41.24 ± 15.61) μm2.The number of neuron of mild pressurc group was(27 ± 2), and the neuron section size was(20. 82 ± 6.57) μm2. The number of neurons of severe pressure group was (22± 2), and the neuron section size was( 17. 96 ± 9.03 ) μm2. The difference between mild, severe pressure group and control group was significant( P ＜ 0.01),while the difference between mild and severe pressure groups was insignificant(P ＞ 0. 05 ). The ultrastructural changes of neurons after chronic pressure were reduced volume of soma, unclear nucleolus and reduced rough endoplasmic reticulum. The lamellar structure of spinal sheath was loose with vacuole, and the cell organs in axial plasma were reduced or lost.CONCLUSION: The ultrastructure of neurocyte changes after chronic pressure in spinal cord. The more serious the pressure is, the more serious the neurocyte damages are. Cell apoptosis exists after chronic pressure in spinal cord.

Objective:To review the experience of closure of the left-main-bronchial stump fistula using endoscopic liner cutter staplers through the right thoracic approach and I stage or staged treatment for the left pyothorax.Methods:6 patients with the left-main-bronchial stump fistula after left pneumonectomy combined with pyothorax were treated by closing the left-main-bronchial stump using endoscopic liner cutter staplers through the right thoracic approach, and pleura was used to cover the distal and proximal incisional margin of the stump respectively. The thoracic T-tube drainage was used in the I stage or staged treatment for the left pyothorax.Results:All patients were survived without recurrence of the bronchopleural fistula. 4 patients were observed to have no recurrence of pyothorax when 1 patient had recurrence of pyothorax and was treated with intermittent T-tube drainage.1 patient operated with left-thoracic fenestration in the past was treated with drainage waiting for secondary operation.Conclusion:The right thoracic approach seemed to be a safer and more effective method than the transsternal transpericardial approach in cases with the left-main-bronchial stump fistula combined with pyothorax. The use of endoscopic liner cutter staplers reduced the risk of bleeding, infection and recurrence of fistula. The T-tube drainage in the I stage or staged treatment for the left pyothorax was considered to be an easier way for treatment.

Objective To investigate the treatment,outcomes and disease burden of severe hand-foot-and mouth diseases(HFMD),and to evaluate the compliance to the 2011 guideline for treatment in regions with a high in-cidence of HFMD.Methods A collaborative study group was established including Children's Hospital of Fudan Uni-versity,Jiangxi Provincial Children's Hospital,Anhui Provincial Children's Hospital,Linyi People's Hospital and the Second People's Hospital of Fuyang City.Clinical manifestation,treatment,prognosis and other data of severe HFMD pa-tients were prospectively collected by filling out a survey form in real time from April 2014 to October 2016. Results Two hundred and twenty-six severe HFMD cases were collected during the research time,including 114 ca-ses in stage 2,75 cases in stage 3,and 37 cases in stage 4.Two hundred and twenty-one cases(97.8%)were given mannitol,with a mortality of 6.2%;91 cases(40.3%)were given mannitol and glycerol fructose,with a mortality of 3.3%;the combined use of mannitol and glycerol fructose might have a better result than the single use of mannitol. One hundred and ninety-eight cases(87.6%)were given intravenous immunoglobulin(IVIG).One hundred and ninety cases(84.1%)were given antiviral drugs.One hundred and forty-five cases(64.2%)were given hormone therapy,and the use of hormone could reduce temperature,but did not reduce the mortality.One hundred and fifty cases (66.4%)needed vasoactive agent,including milrinone,dobutamine,phentolamine and sodium nitroprusside. The vasoactive agent use in stage 3 and 4 were 88.0%(66/75 cases)and 91.9%(34/37 cases),respectively.Sixty-nine cases(30.5%)received continuous positive airway pressure(CPAP),91 cases(40.3%)with mechanical ventila-tion,peak inspiratory pressure(PIP)≥20 cmH2O(1 cmH2O=0.098 kPa)accounted for 61.6%(53/86 cases),po-sitive end-expiratory pressure(PEEP)≥10 cmH2O accounted for 36.3%(33/91 cases).The mean mechanical ven-tilation time was(125.9 ± 101.8)h.Eleven cases(4.86%)died or died after giving up treatment,in which the mortality in stage 3 was 6.7%(5/75 cases),and the mortality in stage 4 was 16.2%(6/37 cases).The death causes were respiratory failure,pulmonary hemorrhage,and circulatory failure. The average time from onset to death was (5.91 ± 5.26)(1-15)d.Length of stay in hospital was(9.18 ± 5.16)(1-37)d in which length of stay in hospi-tal in stage 3 and 4 were(11.3 ± 6.35)d,(11.4 ± 6.62)d,respectively,which were significantly longer than that in stage 2[(7.50 ± 3.04)d],and the difference was statistically significant(P <0.05). The cost was(19 136 ± 12 556)CNY,of which the cost in stage 3 and 4 was(23 121 ± 13 846)CNY,(29 849 ± 16 015)CNY,respectively, which were significantly higher than that in stage 2[(12 961 ± 4 272)CNY],and the difference was statistically sig-nificant(P<0.05). Multivariate analysis found that respiratory rhythm abnormality,capillary refill time more than 3 seconds were risk factors for the deaths in the severe HFMD.Conclusion The 2011 edition of guidelines for treat-ment of children with severe HFMD was well executed.Hormone,IVIG,antiviral drugs did not significantly reduce the mortality of severe HFMD in children.

Objective To investigate the clinical features of severe hand,foot and mouth disease (HFMD) in recent three years,and to analyse the risk factors of severe HFMD.Methods A multicenter collaborative research group was set up,including five children's hospitals(pediatric department)with high incidence of HFMD.Prospective epidemiologic approaches were adopted.After training,staffs from the col-laborative center executed the study by filling up the record forms.Results We collected 114 HFMD cases in stage 2,75 cases of HFMD in stage 3,37 cases of HFMD in stage 4 from April 2014 to October 2016.The age ranged from 2 months to 13 years old,the median age was 2 years old,younger than 3 years accounted for 86.3%.Fever was observed in all the severe HFMD,mean temperature was (39.2 ± 0.7) ℃,fever lasted for (4.54 ± 2.89)d.The mean heart rates in stage 2,3,4 were (128.2 ± 13.3,176.1 ± 22.2,184.2 ± 27.5) times/min,respectively.The mean arterial pressure was (84.4 ± 14.6) mmHg(1 mmHg=0.133 kPa),the mean respiratory rate was (39.0 ± 8.4)times/min,the mean respiratory rates in stage 2,3,4 were (37.8 ± 7.36,38.7 ± 8.13,43.4 ± 10.7) times/min,respectively. Respiratory rhythm abnormality in stage 2,3,4 were 9.6%,14.9% and 56.8%,respectively.The blood glucose increased gradually in 2,3 and 4 stages,the mean blood glucose in stage 4 was(12.4 ± 4.74)mmol/L.The incidence of coma in stage 4 was higher than those in stage 2 and 3. Multivariate Logistic regression analysis found that tachycardia,drowsiness,coma, respiratory rate increase,respiratory rhythm abnormality,capillary refilling time more than 3 seconds were risk factors for severe HFMD.Conclusion The incidence of severe HFMD is still high in children under 3 years of age in last three years.The severe patients have obvious changes in the nervous,respiratory and circulatory system. Tachycardia,drowsiness,coma,respiratory rate increase,respiratoy rhythm abnormality,capillary refilling time more than 3 seconds are risk factors for severe HFMD.

Objective To study the levels of plasma catecholamine( norepinephrine,epinephrine and dopamine) in children with severe hand,foot and mouth disease( HFMD) ,and to assess the influence of cate-cholamine on the pathogenesis of severe HFMD. Methods A collaborative study group was established, including Children′s Hospital of Fudan University, Jiangxi Provincial Children′s Hospital, Anhui Provincial Children′s Hospital,Linyi People′s Hospital and No. 2 People′s Hospital of Fuyang City. Blood samples from children with severe HFMD were collected from April 2014 to October 2016. The levels of blood epineph-rine,norepinephrine,dopamine were measured at 2 h,24 h and 48 h after diagnosis for HFMD. Results The level of epinephrine at 24 h after diagnosis was ( 213. 0 ± 139. 8 ) ng/L in children with pulmonary edema, which was significantly higher than that of children without pulmonary edema[(137. 8 ± 45. 5)ng/L)](P=0. 022). The level of epinephrine at 24 h after diagnosis was (373. 2 ± 298. 1)ng/L in the dead children,and was (144. 2 ± 42. 5)ng/L in the survival children. The concentration of norepinephrine at 24 h after diagnosis was (1935. 7 ± 1824. 1)ng/L in the dead children,and was (858. 3 ± 212. 7)ng/L in the survival children. The levels of epinephrine and norepinephrine of those who died from HFMD were significantly higher than those of survival children at 24 h after diagnosis. There were no significant differences in catecholamine con-centrations among stage 2,3,4 HFMDs at 2 h,24 h and 48 h after diagnosis. Sex and enterovirus 71 virus infection had no significant influences on plasma catecholamine concentrations in children with severe HFMD. Conclusion Plasma epinephrine levels increase in children with HFMD complicated with pulmonary edema. Epinephrine and norepinephrine may play an important role in the death of children with severe HFMD.

OBJECTIVEBy clarifying the natural history of chronic hepatitis B, to evaluate its long-term therapeutic outcome, antiviral drugs efficacy and economic significance.

METHODSA cohort of 183 (mean age of 31.75?.03 years, male/female ratio: 152:31) chronic hepatitis B patients with biopsy-proven and 247 cases of general population as control were followed up by retrospective cohort study. The follow-up time was 11.81?.08 years. This study was focused on long-term clinical outcome including the rate of liver cirrhosis, hepatocellular carcinoma and death, the long-term effect of antiviral drugs and prognostic factors.

RESULTSIn chronic hepatitis B patients, 22 (12.02%) developed liver cirrhosis, 12 (6.56%) hepatocellular carcinoma, and 20 (10.93%) died. The cumulative survival probabilities were 97.27%, 91.62%, and 84.47% in 5, 10, and 15 years, respectively. The cumulative probabilities of HCC were 0.00%, 3.19%, and 11.56% in 5, 10, and 15 years, respectively. In 247 control subjects, 6 (2.43%) died, none of them developed cirrhosis or HCC. The rates of death, liver cirrhosis, and HCC in hepatitis B patients were markedly different (P<0.005) compared with controls. The overall mortality of hepatitis B patients was 4.50 folds of the general population. Cox multiple regression analysis showed that old age, severe histological injury, and the positive HBeAg were closely related to liver cirrhosis, while old age, severe histological injury, and male were major factors leading to death. The independent variable of predicted HCC was not found.

CONCLUSIONSThe long-term outcome of hepatitis B is poor.

BACKGROUND:With the variation of disease treatment modes and the in-depth research on senile osteoporosis in recent years,increasing studies have confirmed that traditional Chinese medicine has a significant effect on the prevention and treatment of senile osteoporosis. OBJECTIVE:To investigate the effect of Yishen Gushu Formula on bone metabolic markers in patients with osteoporosis of kidney deficiency and blood stasis type. METHODS:102 patients with senile osteoporosis of kidney deficiency and blood stasis type who were treated at Ruikang Hospital Affiliated to Guangxi University of Traditional Chinese Medicine from July 2020 to March 2022 were enrolled,including 32 males and 70 females,aged 71-93 years.All patients were randomly divided into two groups,with 51 patients in each group.The control group was treated with calcium carbonate D3 granules and sodium alendronate tablets,while the treatment group was treated with Yishen Gushu Formula beyond the control group.Treatments in each group lasted 3 months.Bone mineral density of the L1-4 lumbar vertebrae and left femoral neck,visual analog scale score,and serum levels of osteocalcin,osteopontin,type Ⅰ collagen cross-linked C-terminal peptide and tartrate resistant acid phosphatase were measured before and 3 months after treatment.Traditional Chinese medicine syndrome score and therapeutic efficiency were also assessed. RESULTS AND CONCLUSION:After 3 months of treatment,the bone mineral density of the lumbar vertebrae(L1-4)and left femoral neck was significantly increased in both two groups(P<0.05),and the bone mineral density of the lumbar vertebrae(L1-4)and left femoral neck was significantly higher in the treatment group than the control group(P<0.05).The visual analog scale scores of both groups after 3 months of treatment were lower than those before treatment(P<0.05),and the visual analog scores of the treatment group after 3 months of treatment were lower than those of the control group(P<0.05).After 3 months of treatment,the serum levels of osteocalcin,osteopontin,type Ⅰ collagen cross-linked C-terminal peptide and tartrate resistant acid phosphatase were significantly improved in both two groups,while compared with the control group,the serum levels of osteocalcin and osteopontin were significantly higher(P<0.05)and the serum levels of type Ⅰ collagen cross-linked C-terminal peptide and tartrate resistant acid phosphatase were significantly lower in the treatment group(P<0.05).After 3 months of treatment,the Traditional Chinese medicine syndrome scores were decreased in both two groups,while the Traditional Chinese medicine syndrome scores in the treatment group were lower than those in the control group.After 3 months of treatment,no significant adverse reactions occurred in both groups.The total effective rate was 88.2%and 70.6%in the treatment and control groups respectively,and there was a significant difference between the two groups(P<0.05).To conclude,Yishen Gushu Formula combined with anti-osteoporosis drugs can significantly improve the clinical symptoms of patients with senile osteoporosis of kidney deficiency and blood stasis type and prevent disease progression by regulating bone metabolism,increasing bone mineral density,and relieving pain.

Objective:To summarize the experience of surgical methods without repairing the fistula for 92 cases with gastrointestinal intrathoracic fistula.Methods:The surgical methods without repairing the fistula were performed through VATS, small incision assisted with VATS or thoracotomy. The focus of the surgery was to promote lung expansion, eliminate the residual cavity of chest cavity and keep effective drainage. After entering the chest cavity from the affected side, wash chest cavity with a large amount of warm normal saline and sterilize intermittently with iodophor to ensure the sterile environment in the pus cavity. Then completely remove the pleural cellulose or fiberboard on visceral pleura to promote lung expansion, eliminate the residual cavity of the chest cavity. The fistula was covered tightly and supported firmly by the visceral pleura on the lung. Multiple T-tubes were placed in thoracic cavity and fistula to keep effective postoperative drainage.Results:Among 92 cases, 85 cases were cured and the cure rate was 92.4% (85/92).7 cases died and the mortality rate was 7.61% (7/92). The 7 dead cases include 5 cases with esophagogastric anastomotic fistula (the death of 3 cases was cause by aortic esophagogastric fistula, the death of 1 case was cause by thoracic gastric tracheal fistula and 1 case was dead because of pulmonary infection and respiratory failure), 1 case with esophageal rupture (the cause of death was septic shock ), and 1 case with esophageal perforation(the cause of death was pulmonary infection and respiratory failure).Conclusion:Most of the surgeries without repairing gastrointestinal intrathoracic fistula are conducted simply through VATS or small incision assisted with VATS., which is safe and effective.

OBJECTIVES: To investigate the effect of borneol on cutaneous toxicity of gilteritinib and to explore possible compounds that can intervene with the cutaneous toxicity. METHODS: C57BL/6J male mice were given gilteritinib by continuous gavage for 28 d and the damage to keratinocytes in the skin tissues was observed with hematoxylin and eosin (HE) staining, TUNEL assay and immunohistochemistry. Human keratinocytes HaCaT were treated with gilteritinib, and cell death and morphological changes were examined by SRB staining and microscopy; apoptosis of HaCaT cells was examined by Western blotting, flow cytometry with propidium iodide/AnnexinⅤ double staining and immunofluorescence; the accumulation of cellular reactive oxygen species (ROS) was examined by flow cytometry with DCFH-DA. Compounds that can effectively intervene the cutaneous toxicity of gilteritinib were screened from a natural compound library using SRB method, and the intervention effect of borneol on gilteritinib cutaneous toxicity was further investigated in HaCaT cells and C57BL/6J male mice. RESULTS: In vivo studies showed pathological changes in the skin with apoptosis of keratinocytes in the stratum spinosum and stratum granulosum in the modeling group. Invitro studies showed apoptosis of HaCaT cells, significant up-regulation of cleaved poly (ADP-ribose) polymerase (c-PARP) and gamma-H2A histone family member X (γ-H2AX) levels, and increased accumulation of ROS in gilteritinib-modeled skin keratinocytes compared with controls. Screening of the natural compound library revealed that borneol showed excellent intervention effects on the death of HaCaT cells. In vitro, cell apoptosis was significantly reduced in the borneol+gilteritinib group compared to the gilteritinib control group. The levels of c-PARP, γ-H2AX and ROS in cells were significantly decreased. In vivo, borneol alleviated gilteritinib-induced skin pathological changes and skin cell apoptosis in mice. CONCLUSIONS Gilteritinib induces keratinocytes apoptosis by causing intracellular ROS accumulation, resulting in cutaneous toxicity. Borneol can ameliorate the cutaneous toxicity of gilteritinib by reducing the accumulation of ROS and apoptosis of keratinocytes in the skin tissue.
