Abstract: Objective To compare the differences in the expression of interleukin-8 (IL-8) and signal transducer and activator of transcription 3 (STAT3) among three groups of individuals: patients with multi-drug resistant tuberculosis (MDR-TB), patients with drug-susceptible tuberculosis (DSP-TB), and healthy controls. By analyzing the differences between these groups, the study seeks to provide a reference basis for clinical auxiliary diagnosis of new type tuberculosis. Methods The differences in mRNA expression profiles of chip from peripheral blood mononuclear cells (PBMCs) among three groups were analyzed. MDR-TB and DSP-TB patients were selected as study subjects, with healthy individuals serving as a control group, and the serum IL-8 concentration of each group was measured using an ELISA assay to compare differences between groups. Additionally, PBMCs from all groups were isolated and total RNA was extracted for analysis of IL-8 and STAT3 mRNA expression using quantitative real-time PCR(Q-PCR). Differences in STAT3 protein expression among the groups were also compared by Western blot assay. Results The serum IL-8 concentration in the MDR-TB and DSP-TB groups was significantly higher than that in the healthy control group, with a statistically significant difference (P<0.05). The relative expression level of IL-8 mRNA in PBMCs of the MDR-TB group and DSP-TB group was also significantly higher than that of the healthy control group, with a statistical significance (P<0.05). Both Q-PCR and Western Blot results revealed that the expression of STAT3 in the healthy, DSP-TB and MDR-TB groups sequentially increased, presenting statistically significant differences between the groups (P<0.05), consistent with the mRNA chip results. Conclusions The expression of IL-8 in active tuberculosis patients (ATB) is significantly increased, which can be used as a marker to distinguish ATB from healthy populations. The changes of STAT3 concentration not only serve as a reference for the diagnosis of ATB but can also distinguish between DSP-TB and MDR-TB populations. The combined detection of IL-8 and STAT3 holds promise as a clinical auxiliary diagnostic basis for different tuberculosis patients.

Evacuation of intracerebral hematomas in 38 hypertensive patients was reported. Hematomas were found in the internal capsule in 24 patients, subcortex in 5. cerebellum in 7 and brain stem in 2. The volume of hematoma was less than 2ml (in the brain stem) in 2 patients, 20-50ml in 15, and over 100ml in 6. The fluid hematoma was to tally aspirated with stereotactic technique in 7 patients. In 17 patients, over 80% of hematoma was evacuated, and in 14 about 60-80% of hematoma was evacuated by the same technic. The results of the operation were good in 11 patients (29.0%), while in 29% there was a mild disability, and in 12 (31.5%) there was a marked disability, 4(10.5%) died.

Objective To investigate time distribution of pressure of footplate in each stage and vertical anti-force from ground of patients with knee osteoarthritis (KOA).Methods 40 KOA patients, 10 aged people, and 10 common saplings were selected to test time distribution of pressure of footplate in each stage and vertical anti-force from ground in period of monopodia support.Results To unilateral KOA patient, there was not obvious difference to be observed in initial contact phase and forefoot push off phase ( P>0.05), but there was a significant difference in forefoot contact phase and foot flat phase between health side and sick side ( P<0.001), and there was obvious difference decreased buffer time and buffer force coefficient between them ( P<0.01).Conclusion To KOA patients, the time decreases in weight-bearing phase and absorption shocks, and amortization coefficient also decreases. These indexes can be used as the walking index of functional assessment and the objective evidence of curative effect.

OBJECTIVEMultiple subpial transection (MST) is one approach to the surgical treatment of intractable epilepsy with epileptogenic lesion located in functional areas. To verify the effect of MST, an experimental study was performed first, followed by clinical application.

METHODSOn the basis of the experimental study, MST was performed in 200 intractable epileptic patients from 1991 to 2000. Of them, 80 cases underwent MST only while 120 others underwent MST combined with other techniques, such as corpus callosotomy, temporal lobectomy and focus resection. A series of modifications of the surgical techniques were made.

RESULTSThe results of the experimental study indicated that MST could inhibit the formation and spreading of epileptic discharge and limit the damage to neurons in a minimal area on the epileptogenic agent injected cortex. MST does not impair major functions of the cortex. After the clinical application and modifications, 160 patients were followed up for 1 to 8 years. Complete control of seizure was obtained in 100 cases (62.5%), significant reduction (more than 75%) in 32, reduction (more than 50%) in 20 and no change in 8. The total rate of effectiveness was 95.0%, and the significant rate of effectiveness was 82.5%. No functional defects were found in any patients.

CONCLUSIONSThe results indicate that MST is an effective approach to the surgical treatment of intractable epilepsy. MST can be combined with other approaches. The outcome of the subdivision of the MST only group indicates that MST on local epileptogenic lesion without structural changes is as effective as that of the combined operation group. To evade hemispheric disturbance, MST should be done first to avoid severe complications. Hemispherectomy should be performed only on poor effected cases of MST.

Objective To investigate the physiological and psychological symptoms of drug abusers under rehabilitation period through labor.Methods A self-designed clinical symptoms questionnaire and Eysenck Personality Questionaire (EPQ) were used to evaluate 1 004 drug abusers under rehabilitation period through labor, and the related symptoms were analyzed.Results The mainly physiological symptoms were fatigue, forgetfulness, aching pain of joints, arrhythmia and discomfort of limbs, and the mainly psychological symptoms are drug craving, insomnia and anxiety. The mean scores of P and E were higher in those who had the drug craving symptoms ( P<0.01), and the mean scores of N were higher in those who had the insomnia or anxiety symptoms ( P<0.01).Conclusion The mainly physiological symptoms of drug abusers under rehabilitation period through labor are fatigue, forgetfulness, aching pain of joints, arrhythmia and discomfort of limbs, which are probably caused by the unbalance of the nervous and internal secretive systems, and the plastisity of the nervous system. The psychological symptoms may due to the effect of morphine and the personality of the drug abusers.

Oral cancer represents a serious public health problem affecting oral and system health with a high global incidence.Treatment strategies for oral cancer vary in different disciplines and are likely to be limited to certain doctor's personal experience.While clinical practice guidelines are considered to enable doctors to determine the most appropri-ate and consistent treatment strategy according to the patient's situation.National Comprehensive Cancer Network(NCCN)clinical practice guidelines have become the most prevalent in global clinical oncology practice.This article mainly focuses on cases to discuss the normalized treatment strategy for oral cancer in different stages based on the NCCN Clinical Practice Guidelines in Oncology(NCCN Guidelines):Head and Neck Cancers,Version 3,2024.

Objective To explore the correlation between TCM constitution and sleep status in escort troops. Methods Standardized TCM Constitution Questionnaire and Pittsburgh Sleep Quality Index (PSQI) were used to investigate escort troops. Factors of PSQI and constitution types were analyzed. Results The results of PSQI showed the number of escort troops who had bad sleeping (PSQI>7) was 64, which accounted for 46%of the escort troops, among which, 45 people (70.3%) were justified as biased constitution, while 19 were normal constitution (29.7%). The top three biased constitution in bad sleeping were:qi deficiency, phlegm-dampness and dampness-heat. PSQI factors such as sleep disorder, daytime dysfunction and total score had positive correlation with qi deficiency, yang deficiency, yin deficiency, dampness-heat and blood stasis, and negative correlation with normal constitution. Conclusion Sleep condition of escort troops has correlation with TCM constitution, which indicates that sleep status could be improved by regulating TCM constitution.

Objective To evaluate the accuracy of CT-guided stereotactic biopsy in making correct pathological diagnosis and choosing corresponding management of brain tumors. Methods From 1991 to 1995, CT-guided stereotactic biopsy was performed in 310 patients with intra-cerebral lesions which were deep-seated or located in certain main functional areas. The patients were 198 men and 112 women. Their ages ranged from 4.5 to 70 years (average: 39.3 years). The lesions were located in the deep cerebrum (74 patients), the sellar area (62), the basal ganglion (51), the posterior part of the third ventricle (38), other intraventricleular area (21), the cerebellum (17) and the brain stem (9), and intracranial multiple lesions were found in 38 patients.Results Brain tumors were diagnosed pathologically in 266 patients (85.8%); inflammatory process in 25 (8.1%), other lesions in 8 (2.6%) and uncertain cases were 11 (3.6%). The overall positive rate of biopsy was 96.4% and the positive rate for brain tumor was 85.8%. Intracranial hematomas after biopsy were found in 5 patients (1.6%). There were no deaths induced by the biopsy or other serious complications.Conclusions The results suggest that CT-guided stereotactic biopsy is a reliable method for histopathological diagnosis of brain tumors and it is also of great help in selecting appropriate management.

Objective: To determine the effect of gut microbiota on a rat model of post-traumatic stress disorder(PTSD)and explore the correlation of gut microbiota with behavior and neurotransmitters.Methods: We established a single prolonged stress(SPS)model to examine the pathogenesis of PTSD on rat behavior,gut microbiota,and neurotransmitter levels.Rats were separated into control and model groups,and neurotransmitter levels were measured using enzyme linked immunosorbent assay.Then,16 S rRNA sequencing was used to compare the gut microbiota between the control and model groups.Results: Compared with those in the control group,freezing time significantly increased,while number of standing upright,crossing frequency,time spent in the central arena,and total distance traveled were significantly reduced in the model group after exposure to SPS(all P<.05).Meanwhile,serotonin,or 5-hydroxytryptamine,levels in the brain in the model group were significantly lower than those the control group(P=.0332).In addition,changes were observed in the gut microbiota diversity and relative abundances of bacterial phyla,orders,families,and genera in the model group.Especially,changes in Firmicutes,Bacteroidetes,Cyanobacteria,and Proteobacteria levels were most pronounced after SPS exposure.Correlation analysis showed that the strongest positive correlation was found between Bac-teroidaceae and 5-HT(P =.0009).Moreover,RF32 abundance was the most negatively related to 5-HT(P=.0009),crossing frequency(P=.0007),and total distance(P=.0003).Conclusion: Our results suggest that SPS model rats showed differences in behavior,neurotransmitter levels,and gut microbiota with control rats.Moreover,Firmicutes,Bacteroidetes,Cyanobacteria,and Proteobacteria were most relevant to the exhibited fear-like and anxiety-like behaviors and significant serotonin content reduction in SPS model rats.
