Abstract: Objective To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) in Ankang City from 2011 to 2021, so as to provide a scientific basis for the formulation of PTB prevention and control strategy. Methods Descriptive statistics were used to analyze the epidemiological characteristics of PTB in Ankang City from 2011 to 2021, and a time series model was established to quantitatively predict the incidence of pulmonary tuberculosis in 2023. Results The incidence rate in Ankang City showed a significant upward trend from 2011 to 2017, and a more obvious downward trend in 2017-2021 (P<0.05), and the decrease rate in 2021 was 40.36% compared with that in 2017. The proportion of etiological positivity increased from 12.5% in 2014 to over 50.00% after 2019. The incidence season was mainly concentrated in the first quarter, accounting for 28.39% of the annual incidence. High incidence areas were concentrated in the south of Ankang: Langao County, Ziyang County and Zhenping County, with 128.32/100 000, 117.07/100 000 and 110.44/100 000, respectively. Low incidence areas were located in the north of Ankang: Ningshan County, with 60.62/100 000. Farmers and students were the high incidence groups, accounting for 81.80% and 4.97% of the total cases respectively. The incidence of young children was relatively low, but cases were reported every year. The incidence rate of male was 2.39 times that of female. The age of onset increased significantly from 15 years old, and the peak incidence was in the age group of 60-<80 years old, followed by the age group of 45-<60 years old, the average annual incidence was 136.44/100 000 and 104.47/100 000, respectively. The model ARIMA(0,1,1)(0,1,1)12 predicted that the incidence of the disease generally increased from October 2022 to March 2023, then steadily decreased, and increased again in December. Conclusions The incidence of tuberculosis varies in different areas of Ankang City, and males, farmers, students and the elderly are all factors of high incidence of tuberculosis. Therefore, different prevention and control strategies should be adopted according to the characteristics of population in different areas. The number of cases in Ankang City in 2023 showed an overall downward trend, which can provide a reference for the prevention and control of PTB.

BACKGROUND:Simple spinal decompression for lumbar degeneration-induced lumbar scoliosis spinal stenosis is difficult to obtain long-term efficacy. Because simple decompression is considered an iatrogenic lumbar instability, and can aggravate lumbar deformity. Posterior lumbar pedicle screw fixation combined with decompression and fusion obtained good curative effects in patients.
OBJECTIVE:To investigate the clinical efficacy of posterior decompression, internal fixation, and bone graft fusion with posterior pedicle screw system in the treatment of degenerative lumbar scoliosis with stenosis.
METHODA retrospective analysis was performed in 18 patients with degenerative lumbar scoliosis with stenosis who received surgical treatment from February 2009 to November 2012. These patients consisted of 6 males and 12 females, with a mean age of 62.2 years (range, 48-80 years). They had lumbar scoliosis with a mean Cobb angle of 28.6° and underwent posterior decompression, internal fixation, and bone graft fusion.
RESULTS AND CONCLUSION:Al the 18 patients achieved satisfactory fol ow-up. The mean fol ow-up was 22 months. Al patients were satisfied with treatment outcomes and had improved quality of life. The mean correction angle was 13.7° (range, 6.0°-28.4°) after operation. There was no failure of internal fixation, and no infected cases were found. These data inducated that posterior decompression, internal fixation, and bone graft fusion is one of the effective methods for treating degenerative lumbar scoliosis with stenosis.

A FAST (fluorescence of advanced Maillard products and Soluble Tryptophan) method for identification of reconstituted milk made from skim milk powder in the fresh milk was developed. Considering milk and skim milk powders variations from different seasons and countries, milk was collected from different dairy farms in different seasons and skim milk powders were collected from different countries to measure the Tryptophan (Trp), advanced Maillard products (AMP) fluorescence values. The results showed that there were differences (P<0.01) between raw and reconstituted milk. The plot of values in each mixed level of raw and reconstituted milk had a correlation coefficient >0.97. The FAST method is a simple, rapid, low-cost and sensitive method enabling the detection of 5% reconstituted milk in fresh milk. The measurement of the Trp, AMP fluorescence values and calculation of the FAST index is a suitable method for large-scale monitoring of fresh milk samples.

OBJECTIVETo evaluate the role of undermining orbicularis oculi muscle from Orbital rim for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.
METHODS56 cases of lower eye baggy deformity with tear trough deformity and palabromalar groove were treated with the procedure of stripping eye orbicularis oculi muscle from orbital rim by a transcutaneous approach in lower blepharoplasty. The orbital septum was opened along the arcus marginalis for releasing the orbital fat. Some orbital fat was removed if necessary. Then the inferior edge of the orbital septum fat was reset over the orbital rim so as to smooth the infraorbital groove.
RESULTS56 patients were available for 6 to 18 month's follow-up. 54 patients were quite satisfied with the cosmetic result. One developed lower eyelid retraction and another one showed asymmetrical subcutaneous local uneven after 1 month's. They were all corrected by the second operation after 3 months.
CONCLUSIONSStripping orbicularis oculi muscle from orbital rim plays an important role for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

BACKGROUND: Pancreatic damage in critically ill patients is associated with the progressive failure of multiple organs, but little is known about its clinical characteristics. At present, no guidelines are available for the diagnosis and management of pancreatic damage. This study was undertaken to analyze the clinical and pathologic characteristics of pancreatic necrosis in critically ill children, and to find some biological markers of pancreatic damage or pancreatic necrosis. METHODS: We retrospectively reviewed the clinical data, laboratory results, and autopsy findings of 25 children, who were admitted to Hunan Children's Hospital, China from 2003 to 2009, and died of multiple organ failure. The autopsy revealed pancreatic necrosis in 5 children, in whom sectional or gross autopsy was performed. RESULTS: The 5 children had acute onset and a fever. Two children had abdominal pain and 2 had abdominal bulging, flatulence and gastrointestinal bleeding. Four children had abnormal liver function, characterized by decreased albumin and 3 children had elevated level of C-reactive protein (CRP). B-ultrasonography revealed abnormal acoustic image of the pancreas in all children, and autopsy confirmed pancreatic necrosis, which may be associated with the damage of the adrenal gland, liver, lung, heart, spleen, kidney, intestine, thymus, mediastinal and mesenteric lymph nodes and other organs. Children 1 and 2 died of acute hemorrhagic necrotizing pancreatitis (AHNP);children 3-5 died of multiple organ dysfunction syndrome (MODS) due to pancreatic necrosis. CONCLUSION: Pancreatic damage or pancreatic necrosis in critically ill children is characterized by acute onset, severity, short course, multiple organ damage or failure. It may be asymptomatic in early stage, and easy to be ignored.
